What to do to keep charging for a long time. How to avoid a dead battery on Android? How to save battery power on Android and iOS

How to increase the battery life on your phone if there is very little charge left and you need to make a very important call in a few hours? Modern people are already accustomed to touch phones, ultra-thin laptops, and other gadgets, practically without parting with technical devices all day long. As active users of mobile and computer technology, we are increasingly asking ourselves the question of how to make the battery last longer? Why does the battery drain so quickly, and how to save battery power to increase the operating time of, for example, a mobile gadget? Consider in this article the site in more detail useful tips to increase the life time of your battery.

Why is the battery on your device draining quickly?

Most people prefer compact gadgets, which is why manufacturers cannot increase the battery capacity - this will affect the size of the device. The more the number of cores in the processor and the more powerful they are, the faster the battery is discharged. However, it often happens that the gadget owners themselves are to blame for the rapid discharge of the battery. V modern smartphones, laptops, computers and other devices have many functions and programs that not every user needs. There are many reasons why your gadget runs out of battery quickly:

Excessive display brightness;
Frequent device reboots;
Wireless interfaces are always on;
Mobile games and social networks;
Included GPS module.

Quite often it happens that you recently charged your phone, but after a few hours half of the charge is gone, and you don't have the ability to charge. And so it is necessary that it is not completely discharged by the time you can charge it. What then is to be done? How to extend battery life without charging? For you, we have prepared TOP-20 tips that will help you increase battery life, no matter what operating system you have on your smartphone or tablet: Android, iOS, etc.

Turn off your phone. If you are not going to answer calls and you do not need your phone anytime soon, then it is best to turn it off. This way you can keep your charge for a long time. If you are going to use it only as a PDA, then activate the "Flight" mode.
Decrease the screen brightness and enable sleep mode. On big screen a bright image consumes a lot of battery power, therefore, disable automatic brightness control, adjust this parameter manually. Sleep mode is the time that the screen will spend in standby mode until it dims and turns off. Many bet about 30-60 seconds, but 15 seconds is best.
Disable background refresh. This function allows minimized applications to continue working in background.
Turn off 3G, mobile Internet. If you do not need to urgently respond to messages in social networks or look for information, it is better to turn off the mobile Internet. This will keep you charged for a long time.
Switch on "Airplane mode". When this function is enabled, communication in the device will be disabled, the battery will drain more slowly, you can save battery power for making an important call.
Disable automatic software updates. You may need to call somewhere urgently, and not update the game, which will also eat up traffic. It is best to disable automatic updates and there will be more charging.
Disable geolocation. This service consumes the battery very quickly, leave this function enabled only for those applications that are needed, for example, in maps, most of the system geolocation services, if unnecessary, can be disabled;
Turn off dynamic wallpaper. They are also called live wallpapers and, compared to regular wallpapers, they waste a lot of power on your smartphone and tablet. Many people recommend putting a black wallpaper on the screen.
Disable Wi-Fi and Bluetooth. It is better to turn off Wi-Fi, especially if you are on a train where there is no Wi-Fi zones... It also takes a lot of charging to find this signal. It's generally better to turn on Bluetooth when you really need it.
Leave Push Notifications exclusively for very the applications you need ... And if you know that you are not going to receive messages in the near future, then it is better to remove Push notifications.
Disable automatic check of mail (e-mail). For the duration of the trip, especially if you are on a train where there is not even WI-FI, it is recommended to turn off automatic mail checking. It's pointless, and your phone or tablet will waste energy on it.
Turn on automatic blocking screen... Turn off the screen immediately after you stop using the gadget.
Enable Do Not Disturb mode. In this mode, you will receive only those calls that you expect, unnecessary calls will be automatically dropped.
Update the operating system, which can fix the moments associated with the duration of the battery without charging;
Do not turn on the phone unnecessarily. Save power even if you are addicted.
Buy a spare external battery. Purchase external battery for the ability to charge the gadget on the road. Or you can purchase PowerBank, which are very popular now and help you charge your device at any convenient time.
Switch your smartphone to offline mode until the moment mobile connection will not be of high quality again. This is necessary if you are in a poor connection area, as the smartphone will constantly search for a network.
Turn on GPS, since this is the most power-consuming function, it is strongly discouraged to leave it on without the need;
Turn off the accelerometer. This device is best turned off as it can save you enough battery power on your tablet or smartphone.
Use the Battery Calibration app which will reset the battery memory and allow it to be overclocked again.

How to properly charge a new device?

So you bought yourself a new smartphone or tablet, and now you need to "overclock" the battery so that it works at full capacity. There are general guidelines for battery preservation. Regardless of which device you bought, follow these guidelines:

The device must be used until the battery is completely discharged;
It is recommended to discharge the gadget within 12 hours from the date of purchase;
The battery should be fully discharged and recharged 3 times.

It is best to use the native charger that comes with the gadget. Other chargers, even those that fit your socket, may not have the correct wattage.

Thus, now you know how to make the device hold a charge longer, and you can at any time without fear that you will not have time to call a person, or wait in time incoming call... Save battery charging, charge the device on time and correctly, and your battery will not be discharged "at the wrong time".

With bright screens require a lot of battery power.

But apart from the screen, different applications can consume battery power.

What should be done to prevent the phone from draining quickly and keeping its battery as long as possible?

First you need to answer the question: "How do smartphone batteries work?".

Most smartphones have either lithium-ion (Li-ion) battery, or lithium polymer battery (Li-pol), and such batteries do not need to be fully charged and discharged at the very beginning of using the smartphone.

But such batteries can suffer from problems with low voltage so it's better than them partially charge (between 20% and 90%) rather than fully charging and discharging.

There is still debate about caring for these batteries, the main thing is to find what is best for you.

How to increase battery performance

Here are some tips on how to make your smartphone battery last longer and not drain quickly:

1. Screensaver and themes in dark colors.

If your device has an AMOLED screen (like most Samsung devices), use dark tones for the screen - this will help conserve battery power. AMOLED screens only illuminate colored pixels. Black pixels are not highlighted, which means the more of them you have, the more energy you save.

2. Don't use automatic brightness.

This feature may sound useful, but automatic brightness usually makes the screen much brighter than it actually needs. Your best bet is to manually set the screen brightness and change it whenever you need it. This is a very important point because the screen is a major waste of battery power.

3. Set the sleep mode (screen timeout) for the shortest possible time.

Just think, if your screen automatically turns off after 1 minute, it will consume 4 times more energy than if this indicator is on for 15 seconds.

Studies have shown that, on average, a user turns on their smartphone 150 times a day, which means that everything possible should be done to reduce screen work.

4. Do not use unnecessary functions such as animation or smart scrolling. they also use up your battery.

Long battery

5. Turn off vibration.

It is also worth turning off the vibration of the phone when pressing the keys - this may seem like an interesting function, but it is useless and only consumes the power of your battery. Of course, if you absolutely need this function, then this item can be skipped. Your phone needs more power to vibrate than a simple call.

6. Use lock screen notifications.

The lock screen can help conserve your battery. This is because you see all the notifications at once, without having to turn on the entire screen. This screen is on by default on all smartphones with the Android Lollipop operating system.

If you have an operating room Android system KitKat ( previous version), try using lock screen widgets if your RAM it supports it, or you can install an application that does it for you, such as Dynamic Notifications.

You will still have to turn on the screen, but it will be on for a much shorter time than usual. In addition, the screen will be dark, which will also conserve battery power.

7. Set the "Do Not Disturb" "function.

This function allows you to activate the silent mode, and the user will know about all alerts when the phone vibrates.

Also given utilities turns off Wi-Fi and mobile internet. When you are at work and do not want to be disturbed, set the mode in which the phone will not ring and vibrate.

You can also turn on airplane mode when you decide to take a break.

When you install applications such as Greenify, the applications that you normally run on your phone regularly will turn off and go to "sleep" mode when you are not using them.

Extending smartphone battery life

8. You don't need to be connected to networks 24 hours a day.

Turn off GPS, Bluetooth, Wi-Fi and mobile internet when you don't need them. You can use either Wi-Fi or 3G or GPS to find out your location and navigation, but not all of them.

9. Try to limit the use of widgets, especially those that require an Internet connection.

Widgets that show the weather, as well as widgets for Twitter, Gmail and some social. networks need constant updating, which means they need energy.

It's better to just turn on this or that widget when you need it, without leaving it working and updating on its own.

Over time, Android devices start to drain much faster than they used to. In some cases, you can fix this problem yourself, and sometimes the only way out of the situation is to buy a new battery.

There may be several reasons why a tablet or phone stops holding a charge:

Battery buildup

This item should only be considered if you are using an old phone or tablet.

This method of solving the problem of rapid battery discharge is suitable for a nickel metal hydride (NiMH) battery, which, as a rule, can be installed on older models of phones and tablets. On modern devices, lithium-ion (Li-Ion) batteries are installed, which do not require buildup.

To find out what technology your battery is made by, you need to determine the model of the device or study the information written on the battery itself.

Buck is a repetition of a full discharge cycle and then a full charge of the phone several times in a row. Please note that this technology is only worth using on nickelin batteries, on others it will not only be beneficial, but also harm.

To swing the battery:

When the battery is completely discharged, turn off the device and charge it fully.
Remove the battery from the device, hold it in this state for two minutes, and then reinsert it. If the battery does not work properly, a notification will appear on the screen that the phone is not fully charged, for example, to 95%. Without turning on the device, repeat the charging process to 100%.
Discharge the device completely. Repeat these steps until the battery, after you pulled it out and put it back in, starts to show a full charge. The charge level should not drop or change after handling the battery.

Battery Calibration

Unlike wobbling, it is recommended that all batteries be calibrated if they have been found to have problems with retention. If the device quickly sits down, turns off, when the displayed charge level is not zero, does not fully charge, then it must be calibrated. Thanks to this procedure, the device will understand what is actually the maximum volume of the battery, and in the future will give it the opportunity to fill up completely.

Through a third party application

Since Android does not have a battery calibration application by default, you will have to download it from the Play Market:

Video: Calibrating a Battery Using Battery Calibration

No third-party programs

To calibrate the device without using third-party programs, follow these steps in sequence:

What to do if calibration and buildup didn't help

If the above methods did not help you return the previous charge retention time, then one thing remains - to replace the battery. Batteries are sold separately and can be purchased at most stores that sell phones and tablets. When buying, be guided by the model and the size of the battery. Before you pay, check if the battery fits your device model and if it works with it.

Battery care

Try to adhere to the rules below so that the battery of any device will serve you as long as possible.

Recommendation	Description
Charging lithium-ion batteries	Do not charge lithium-ion batteries to 100%. It is better to do several short recharges than one full charge.
Full discharge	Do not allow full discharge when the device shuts down by itself. Try to charge your phone or tablet on time.
Temperature	Keep your device at a balanced temperature. Do not place it in a very cold or excessively hot place.
Processes and Applications	Disable unnecessary processes and programs immediately after you stop using them.
Charging cable	Watch out for the safety of the cable. Try to use only official cables.
Port	Make sure the port where the charging cable is connected is clean. When wiping it, proceed very carefully so as not to damage the microcircuits in it.
Do not load the device for a long time and with a large number of heavy applications or games. This causes the phone to become very hot, which negatively affects the battery.

It is very important to keep an eye on the battery. Perhaps this will not extend its service life, but it certainly will not let it break down before the end of the warranty period. Observe the above guidelines and remember to care for lithium and nickel batteries differently.

Almost all users of mobile gadgets face the problem of discharging the battery too quickly. The problem occurs gradually and for some time remains unnoticed, but one day the owner notices that the time autonomous work smartphone or tablet has almost halved. If you do nothing, it will decrease further - until it becomes impossible to use the device. And one day the device will not turn on at all.

Let's talk about why the battery on Android devices runs out quickly and how to prolong its life.

Reasons for fast battery discharge

The actual battery capacity of your smartphone or tablet is lower than the specifications.
Battery capacity has decreased due to normal wear and tear.
The ambient temperature is below +5 ⁰C or above +30 ⁰C.
Included too high level screen brightness.
Resource-intensive features included: GPS, NFC, Bluetooth, etc.
Long distance to the base station of the mobile operator.
Applications and widgets that run in the background consume energy.
Frequent switching on and off of the device.
Infection with mobile viruses.
Malfunction operating system or hardware, as a result of which certain resource-intensive functions or the device itself are not turned off.

Battery capacity is lower than in the passport

Inconsistency real capacity The battery indicator, which is indicated in the passport of a smartphone or tablet, is more common than you think. There are just very few users who dare to double-check it. Most believe the documents, as well as the indicators of the programs, which also do not always display reliable data.

The reason for the discrepancy between the actual information and the nominal does not always lie in deception on the part of the manufacturer or seller (although this is also the case), it is just that lithium power supplies lose their capacity during long-term storage. If you bought a device that was released a year ago, even with proper storage, its battery became less capacious by 2-6%, and with the wrong one (i.e. when charged up to 100%) - by as much as 15-30%.

To calculate the real capacity of the battery, they use charging and discharging devices like iMAX, or self-made dischargers complete with a multimeter or USB tester. The exact readings are determined during the discharge of a fully charged battery.

If your phone's battery capacity is less than advertised, then it will discharge in a shorter time than expected. And, alas, it is impossible to influence this.

Capacity has decreased over time

The deterioration of the battery becomes noticeable after 1.5-2 years of using a smartphone or tablet. But it may come earlier if:

often and for a long time to use the device at low and very high air temperatures (room temperature is the most favorable for the operation of lithium batteries);
allow a discharge close to 0%.
charge the device near heat sources;
store an unused battery in a state of 100% charge at a high ambient temperature (for storage, the optimal charge level is 40-50% and the temperature of the refrigerator);
charge the battery with a higher voltage and currents than the manufacturer provided (the required level of current and voltage is indicated on the charger that was sold with the gadget).

Frequent short-term recharging, contrary to popular belief, does not harm the battery. A much greater influence is exerted by the current with which it is charged. It is preferable to charge lithium batteries with low currents, although this takes more time.

If your device's battery capacity has decreased due to wear and tear, the only solution is to replace the battery with a new one.

Using the gadget in cold or hot weather

When using a mobile device in unfavorable temperature conditions (up to +5 ⁰C and above +30 ⁰C), the battery is discharged much faster, but at temperatures close to room temperature, its capacity is immediately restored to its original level.

If you do not do this too often, the battery will not wear out quickly, but for calls in the cold it is still better to use a headset and keep the phone in a warm pocket.

High screen brightness

The screen of a mobile device on Android is the main consumer of energy. The brighter it is backlit, the faster the battery will drain.

The use of adaptive backlighting, which changes depending on ambient light, helps to reduce battery consumption (available only on devices equipped with a light sensor). To enable it, select the Auto checkbox in the screen brightness settings. And so that the screen does not remain on when you are not using the gadget, configure it to go into sleep mode after 30-60 seconds of inactivity.

Resource-intensive functions

The next active consumers of energy after the screen are:

geolocation;
live (animated) wallpapers;
NFC and Bluetooth;
mobile Internet (3G, 4G).
Wi-Fi.

If they are all involved at the same time, even the most capacious battery will discharge very quickly, so whenever possible, turn off what you are not using.

Unstable cellular connection

You may have noticed that during a long stay in places where the phone does not pick up the signal of the operator's base station, for example, outside the city, the battery is discharged faster than usual. This is because more energy is expended to maintain an unstable, lost connection.

The battery will drain faster even if the problem is with only one of the two SIM cards. To save charge, it is better to turn off such a SIM card for a while.

Apps and widgets running in the background

Many Android applications and widgets, after installation, register themselves in autostart and work in the background all the time while the device is turned on. When there are many such applications, the device not only discharges very quickly, but also noticeably slows down, so autorun should be controlled and allowed only to those programs that need it (antivirus, optimization tool, utility utilities, instant messengers, etc.).

Unfortunately, the autorun control functions are custom and system applications in Android no. But it becomes available after receiving root rights(superuser) and installing special utilities on the device, such as:

Startup Manager and some others

There are utilities that allow you to manage startup without root rights, but they do not work on every gadget and not always correctly.

Applications that were launched by the user himself can also consume battery resources, but after they became unnecessary, he forgot to close. The accumulation of such programs not only loads, but also heats up the processor, and from it, in turn, the battery heats up. And when heated, as we know, the phone's battery runs out very quickly.

Control over the processes actively consuming energy is also best entrusted special utilities... For example, the following:

- DU Battery Saver etc.

By the way, the capabilities of most of them include cleaning the system from unnecessary files, CPU cooling, charging optimization and a number of other tasks. To keep the device in order, it is advisable to use one of these utilities constantly.

Frequent reboots and switching on / off the device

In order to save power, some users regularly turn off their mobile gadget. Sometimes even several times during the day. This is another reason for the battery draining too quickly, as the power consumption is close to maximum when the device is started and the operating system is loaded.

Until you use an Android smartphone or tablet, you should not turn it off completely - just turn off the screen, complete resource-intensive tasks, turn off communication functions (Wi-Fi, GPRS, 3G-4G Internet, GPS, NFC and Bluetooth), background transmission data, sensors and vibration motor. To do this, most mobile gadgets have a power saving mode, the power button of which can be located in different sections of the settings (parameters) menu.

Infection with mobile viruses

Malicious programs that attack Android devices do not always operate openly. Often they conduct activities that are invisible to the user, and the signs of their presence are only empty accounts and very fast battery discharge, including in standby mode.

Latent viral infection should be excluded for any non-standard gadget behavior, for example:

The phone or tablet wakes up without any active action on your part.
The device heats up while in sleep mode.
On the device, without your participation, Wi-Fi, geolocation, mobile internet other. Or they cannot be turned off.
Unknown numbers appeared in the list of outgoing calls and SMS, and in the browser history - views of sites that you have not visited.
An application has designated itself as the device administrator without your knowledge.
For unknown reasons, they stopped starting Google play antivirus and other security applications.
Any system functions stopped working.
The volume of the device's network traffic has increased for no reason.

System or hardware failure

Some PC and laptop users have encountered such a problem as an incomplete shutdown of the computer, when the screen goes blank when the operating system is shut down, but some of the devices remain in an active state - the cooler continues to rotate, lights are on, etc. Exactly the same problem occurs on mobile devices, it's just not so easy to notice, because smartphones and tablets do not have a cooler, and the indicator shows only the charging stage. In case of such malfunctions, the device, in fact, remains on all the time and, accordingly, even in the “as if off” state, it actively consumes battery power.

The causes of such problems can be faulty applications, viruses, operating system errors and a malfunction in the hardware of the device (including connected devices - memory cards, SIM cards, etc.).

The only symptom that allows one to suspect an incomplete shutdown of the device is too much battery consumption at a time when it should be minimal. And to make sure whether this is really your case, you just need to remove the cover of your phone (tablet) and check the processor temperature with your fingers. If the device continues to operate after being turned off, the processor will remain warm. Sometimes, in this state, the body of the device heats up slightly, but sometimes it does not - it depends on its design.

What the user can do in such cases without contacting the masters:

Remove applications that were installed before the problem appeared (if it was possible to fix the time of its start).
Conduct antivirus scan.
Disconnect all connected devices.
Reset the system to factory settings.
Remove the battery (if it is removable), hold down the power button for 20-30 seconds and replace the battery.
Reflash the device with a known working firmware.

After each manipulation, check the gadget by turning it off. If the problem is not solved, you will have to take it to the service for repair, since the malfunction itself will not disappear, and the battery will use up its resource much faster than during normal operation.

The eternal dispute between the warring parties was resolved by experts: if you want your battery to last longer, you should not constantly keep the device on charge. Tech enthusiast Eric Leamer argues that a full charge is fatal to phones.

He believes that they need to be disconnected from the network before the battery level reaches 100%: “But on the other hand, if you constantly discharge the phone“ all the way ”, then this will not save the situation, on the contrary - too frequent experiments with cycles can damage the battery. Although if you do a full discharge about once a month, it can be useful. "

Leamer urges users to try to keep the charge level above 50 percent, if possible. But he warns that if you leave the device in the outlet after it is fully charged, the battery will wear out much faster.

In short, according to him, the optimal charge level is between 40 and 80 percent. He also debunked the existing myth that new phone needs to be charged within 72 hours before use. Ostensibly, he then "remembers" what it is like to be fully charged.

enthusiast technician It is a fact that batteries have memory. But this only applies to nickel batteries, not the lithium-ion batteries used in newer phones. Your faithful companion is undoubtedly equipped with a lithium-ion battery, so it needs to be treated a little differently

How exactly?

First, put your smartphone on charge at every opportunity. Second, keep it cool. The recommended storage temperature for most batteries is 15 degrees Celsius. The maximum temperature is between 40 and 50 degrees.

Leamer noticed that if you store a lithium-ion battery at 25 degrees, then in a year it will lose about 20% of its maximum capacity. At 40 degrees, this figure rises to 35%.

Plus, it's best to avoid wireless chargers... When they work, they generate heat, which literally "roasts" your battery.

Also, do not make the screen too bright and constantly use GPS-enabled applications (for example, maps). And if you are in an area where the signal is weak, turn on the flight mode, this will prevent your phone from running out of battery, constantly trying to find a connection. If you are not using your phone, lock it or turn on silent mode.

A table showing how temperature conditions affect the battery capacity:

The optimum operating temperature is from 0 ° to 35 ° C. So store your smartphone at room temperature - for example, at 22 ° C, this is ideal.

Look at the statistics of phone usage: if you know how you usually use the device and how much the battery usually "holds", it will help you to prolong its work.

Pay attention to two things - active and hibernating. Active mode is all the time when you are talking on the phone, checking mail, listening to music, surfing the Internet, sending or receiving text messages... The activated automatic check of incoming messages is also an active mode. Sleep mode is the time when the phone is disconnected from charging, but not in use.

Always update your software!

Turn down the brightness! A very bright screen eats up a huge amount of energy. And if such a function is available to you, then turn on the automatic brightness adjustment - then the screen itself will choose the optimal mode based on the illumination parameters.

Turn off notifications: maybe it's better to sync accounts and check email manually, thereby saving precious battery?

Use geographic services to a minimum: apps that constantly ask for your location and GPS maps drain your battery very quickly.

Use flight mode in areas with weak or no signal! Your device in such places constantly tries to find a network and spends a colossal amount of charge on it.

Lock your phone when you are not using it. You can still receive calls and messages, but nothing will happen if you don't constantly touch the screen.

Use your phone regularly: For the lithium-ion battery to function properly, electrons must be constantly in motion.

Perform a full charge / discharge cycle at least once a month. That is, first charge the phone to 100%, and then completely discharge it.
