How much is 3000 mah. Smartphone with a powerful battery. Offers on Aliexpress
When choosing a device, the decisive factor is the duration of its operation from a single battery charge. However, besides this, a very important factor is the speed of the charging itself. Agree, not everyone wants to charge the device for about four hours. The days of leaving your phone on charge all night are a thing of the past, and with them the technology of charging. For example, Qualcomm's QuickCharge 2.0 technology is very common today. Many of the following support her, and this is probably what allowed them to break into the lead.
Thanks to new technology"Fast Adaptive Charge", created by Samsung, the company managed to significantly increase the speed of charging, thus beating its main rivals in the form of QuickCharge 2.0 and VOOC.
As smartphones today are getting shorter, manufacturers are forced to look for solutions other than increasing battery capacity. A good solution was to increase the charging speed in order to somehow compensate for the lack.
Oppo Find 7a charges in just 1 hour and 22 minutes. Considering the battery capacity and the fact that the device is charged up to 75 percent in just 30 minutes, the Find 7a can be safely put on a par with the S6.
3. Samsung Galaxy Note 4
"Fast Adaptive Charge" came in handy here too. The smartphone charges very quickly, given the large size and battery capacity. With live communication with Note 4, no one would have thought that he was capable of this, however, like me.
4. Google Nexus 6
The Nexus 6 was only 3 minutes behind the nearest competitor. However, the device is still charging decently, the Motorola Turbo Charger, which works in conjunction with QuickCharge 2.0 technology, played a significant role in all this.
5. HTC One M9
HTC One M9 received full support for QuickCharge 2.0, including supported Charger. This allowed the device to break into the fifth line of our rating.
6LG G3
2 hours is, of course, not so little, but relatively little. That is why the device gets a well-deserved 6th place.
The OnePlus One is similar to its Find 7a in many ways, but the only thing that makes it different is the lack of VOOC technology. Flagship killer? I do not think. But even this is worthy, given the capacity of the battery.
8. Samsung Galaxy S5
Last year's flagships can kick ass, and the Galaxy S5 good example this. Yes, it's plastic, yes, it looks rather indistinct compared to the S6, but, as they say, "a flagship is a flagship."
9LG G4
Modern top devices do not last long. And the LG G4 is a good example of this. But it also charges rather slowly. It's all because of the lack of QiuckCharge 2.0 supported charging in the kit. The problem is solved by visiting the online accessories store.
10. Samsung Galaxy Note 3
Galaxy Note 3 deservedly took the 10th line of our list. Compared to Note 4, it is not as attractive, but as a cheaper alternative, it is quite a good choice. The only question is the upgrade to Lollipop, after which its owners faced charging problems: charging takes place through firmware, which, according to the owners, behaves very strangely. Perhaps with further updates the problem will be solved.
11. Apple iPhone 6
Many of our readers have asked to add Apple competitors to the comparison as well. Did you ask? Made. Many Android users will be pleased with the results. But to the owners of Apple equipment, we will only say: “You can get a good discount when iPhone replacement on an Android device in select stores."
If anyone is interested in the indicators of the iPhone 6 Plus: 2 hours 51 minutes. True, the device lives a little longer: 6 hours and 32 minutes.
12 Motorola Moto X (2014)
Motorola's flagship shows us very questionable results. It is not clear, however, what this is connected with. The battery is not so capacious, perhaps they saved on the components, because the device is relatively inexpensive.
13. Sony Xperia Z3 Compact
10 hours of life is very worthy. That is why he can be forgiven for such unattractive results in the charging speed test. However, there is nothing more to add.
14. Sony Xperia Z3
Almost 4 hours of charging? Perhaps even the time of work here will not help soften the verdict. The Z3 will spend half of its life behind an outlet. Do you buy a smartphone as a mobile device or a stationary device for home use?
What are the models of smartphones with a battery of 3000 mAh or more
Continuing the series of articles about smartphones with powerful batteries, today we will look at models with a battery of 3000 mAh or more. There are many such devices on the market today. In general, most smartphones from the middle price category have batteries with a capacity of 1800 to 2500 mAh. So, models with a battery of 3000 mAh and more cost a little higher in this rating. But these are not necessarily top-end smartphones from well-known companies, but rather the opposite. Eminent manufacturers are just starting to turn towards increasing time battery life your gadgets. This is a new requirement of users and it cannot be ignored.
In the meantime, most smartphones with capacious batteries are produced by little-known companies. There are quite a few proposals. Quite a lot of models powerful battery found among. Basically, all phones that are equipped with a battery of 3000 mAh or more have decent hardware specifications. But they cannot be called top and record. In principle, this is not necessary.
Most users are satisfied with the performance of an average smartphone. The main thing is that he works longer in offline and fully justified its name - a mobile phone.
So, consider smartphones with batteries from 3000 mAh.
This is a rather expensive (40-45 thousand rubles) smartphone with powerful hardware and a high-quality display. The battery capacity is 3000 mAh. The device has the ability to work with two SIM and a display with a diagonal of 5 inches. The resolution is 2560 by 1440 pixels.
The LG G4 H818 has an 8MP front camera and a 16MP main camera. The latter is equipped with an LED flash. We will write down a CPU with 6 cores, running at a clock frequency of 1800 MHz, as an asset of a smartphone. It works with 3 gigabytes of RAM. The internal memory is 32 GB. It can be expanded with memory cards.
A 3000 mAh battery will last at least a day of active use. If you use the LG G4 H818 moderately, the battery will last two days. Given the large display and powerful hardware, this is a good result. Some users in the reviews complain about the inconvenient phone interface.
With a 6000 mAh battery installed, the Highscreen Boost 2 SE becomes quite unwieldy. This is the payoff for long battery life. With this battery, the smartphone can show video for 21 hours or withstand 14 hours of surfing the Internet via 3G.
Under the cover is a processor with four cores and 2 GB of RAM. There is a slot for memory cards. The face of the device is a 5-inch IPS display. The main camera has a matrix of 13 megapixels. Weight with a 3000 mAh battery is 151 grams, and with a more powerful battery - 203 grams.
A device with a capacious 3000 mAh battery. The cost of a smartphone is about 15 thousand rubles. Among the features we can note the presence of 2 slots for SIM cards. Otherwise, the characteristics of the hardware are average.
Display Vibe Z2 with a diagonal of 5 inches and a resolution of 1280 by 720 pixels. Two cameras: front 8 MP, main 13 MP with LED flash. The processor has 4 cores and operates at a clock frequency of 1200 MHz. 2 GB RAM and 32 GB available internal memory.
Many users note that the Vibe Z2 phone works without braking. Good assembly, the details fit perfectly, nothing creaks anywhere. The 3000 mAh battery is enough for a long period of "autonomous navigation". At the same time, the smartphone normally copes with resource-intensive applications and even modern toys.
Chinese manufacturer Huawei has launched the Ascend Mate 7 in the category of smartphones with a battery over 3000 mAh. To be more precise, the battery capacity of this model is 4100 mAh. The price is approximately 21-23 thousand rubles.
The device has a display with a diagonal of 6 inches and a resolution of 1920 by 1080 pixels. Front-camera has a 5 megapixel sensor, the main one is 13 megapixels. At the center of the hardware is an eight-core processor running 2 GB random access memory. The internal memory of the smartphone is 16 GB. It can be expanded with memory cards up to 64 GB.
Installing such a powerful CPU is fully justified, since there is a large screen and a powerful processor. The battery capacity is enough for 2-3 days of use with medium intensity. The 4100mAh battery is twice the capacity of most smartphones in this category.
The smartphone is the leader in terms of battery capacity in this review. It is equal to 5300 mAh. This is equivalent to 33 hours of talk time or 22 hours of video playback without recharging. On the Internet without recharging it will be possible to climb 16 hours.
In addition, the Xenium W6610 has a "magic button" that turns on power saving mode. In this mode, the brightness is reduced, Wi-Fi, Bluetooth, GPS wireless modules are turned off. The battery of the smartphone charges very quickly, which is important with such a large capacity. The battery can charge for a day in just 10-15 minutes of charging if you are in a hurry to work. In standby mode, a smartphone with a fully charged battery will last 1200 hours.
For the rest of the components, it can be concluded that Philips Xenium W6610 is a mid-range phone. He has a display with a diagonal of 5 inches and impact-resistant glass. The camera has a resolution of 8 megapixels. The heart of the device is a four-core processor. Supports work with memory cards and 2 SIM. By the way, you can read the article about. The cost of Philips Xenium W6610 is about $220─240.
Another smartphone with a 3000 mAh battery that came to us from the Korean Peninsula. The price of this gadget is about 20 thousand rubles. I must say that the device has a lot of positive feedback from users.
Attracts a beautiful display with a diagonal of 5.46 inches and a resolution of 2560 by 1440 pixels. Good quality Pictures are taken by a 13MP camera with LED flash. The front camera has a resolution of 2.1 MP and is suitable for video calls. If this is not enough, then we advise you to read the material about. Perhaps there you will find something for yourself.
The heart of the LG G3 D855 is a quad-core CPU, clocked at 2500 MHz. Available 2 GB of RAM. The internal memory has a capacity of 16 GB and can be expanded with memory cards. As mentioned above, the operation of the smartphone in offline mode is provided by a 3000 mAh battery. In general, very decent smartphone With high-quality sound, good equipment, modest size and weight. High-quality assembly, flash, flashlight, powerful battery.
Asus has also entered the club of manufacturers of smartphones with a powerful battery. ZenFone 2 ZE551ML has a 3000 mAh battery and will cost the buyer about 18 thousand rubles. It should be noted that Asus release very reliable and quality phones, although they are not the leading company in this market.
ZenFone 2 ZE551ML has a 5-inch display with a resolution of 1920 x 1080 pixels. The front camera has a resolution of 5 megapixels, and the main one is 13 megapixels plus an LED flash.

That is, the hardware of the ZenFone 2 ZE551ML smartphone is quite productive and a powerful 3000 mAh battery is appropriate here. High-quality display and camera, ergonomics - all this is said by users in their reviews of Asus Zenfone 2 ZE551ML.
A power bank (or portable charger) is an energy store that can power gadgets in the absence of an outlet.
Portable external batteries have become a real find and salvation for modern users, because with their help you do not need to worry about the gadget's low battery when you are actively using it.
The use of external batteries is quite wide:
- a camping trip where there will be no outlets nearby
- long flight or train ride
- active use of the smartphone when the battery is not enough for a day.
- small battery size
Choosing a power bank can be tricky because they differ in size and features. For example, some power banks can only charge your smartphone, so if you want to charge something bigger (like a tablet or digital camera), you will need a more powerful external battery.
But how do you know which power bank is best when price isn't the main factor? In this article, we will give some tips on how to right choice portable charger.
Capacity
The capacity of a power bank is measured in milliamp hours (mAh). This is the most important parameter this device. It determines how many times the external battery will be able to charge your device. Usually the capacity varies in the range from 3000 to 25000 mAh. The larger the capacity, the more times you can charge your gadget. If you need a simple power bank to recharge your smartphone in case of emergency - 3000 mAh should be enough for you.
If you take a 10000 mAh power bank, you can charge your smartphone several times. Larger devices like tablets are more power hungry and will need a larger power bank - at least 10000 mAh. But do not rush to divide the power bank capacity by the battery capacity of your smartphone and thus calculate the number of charges. This is not entirely true. Each power bank with a capacity of 10000 mAh says in small letters that in fact its capacity is less. As a rule, 30% must be subtracted from 10000 mAh and you will get real capacity external battery. The remaining mAh are "lost" in the voltage conversion.
For reference, we give the battery capacity of popular smartphones and tablets:

Xiaomi Redmi Note 4 |

Samsung Galaxy S7 |

Apple iPad 2017 (tablet) |
Current strength
The output current, which is measured in amps, determines how fast the power bank can charge your smartphone. The more amps output, the faster the device will charge using a compatible USB cable. You can find a power bank with 1A or 2.4A output power. Most smartphones can easily handle 1A current, but tablets usually need more power or they will take a long time to charge. It is best to take a power bank that produces a current of at least 2A.
Also be sure to ask if there is support for Quick Charge 1.0, 2.0 or 3.0 technology in the power bank. It will allow you to charge devices compatible with this technology (for example, Samsung Galaxy S7) very quickly. The minimum output current is also important when charging Bluetooth headsets and fitness bracelets.
Number of USB ports
The number of USB ports affects how many smartphones you can charge with the power bank at the same time. The more ports a power bank has, the more devices you can charge at the same time. As a rule, they are equipped with one or two USB ports. The newest and most expensive models are supported USB Type-C. If a power bank has two ports, then they usually charge with different current strengths: 1A and 2.1A.
So, for example, you can simultaneously charge a smartphone through a 1A output and a tablet through 2.1A. In this case, it must be taken into account that two smartphones will charge faster than a smartphone and a tablet. V everyday use one port is enough.
Input current
This parameter is also important, because it affects how quickly the power bank can be charged from the mains. It is measured in amperes. As a rule, it varies from 1A to 2.4A. The higher the number, the faster your portable assistant will charge. We recommend buying a device with a current of at least 2A.
Battery type
Do not forget about the type of batteries in the power bank. As a rule, it is lithium-ion or lithium-polymer. The second is a little more complicated in circuitry, but safer and more compact. Plus, lithium polymer batteries have low self-discharge. In terms of efficiency, they are almost equal.
Manufacturer
It is better to pay attention to well-known brands such as Samsung, Asus, Xiaomi, Huawei, TP-link. It is better to avoid the Chinese “noname for inexpensive”; manufacturers from the Middle Kingdom often put cheap electronic components, which affects security. The second reason is the inconsistency with the declared characteristics. The packaging says 10000 mAh, but in practice it turns out to be less than 5000 mAh.
Design and other details
Design is one of the last points on which you need to choose a power bank. No need to wait for crazy performance from an external battery in the form of a bear or a hare.
Having a flashlight would be a plus. Possibility to charge power bank with solar panels- a very dubious function that does not work in practice, and given the weather in Belarus, does not work doubly.
Consider LiPo labeling batteries on the example of a battery, on which there are the following inscriptions:
- 3000 - capacity in mAh (mAh);
- 11.1 V- nominal voltage;
- 3S- the number and order of connection of cans (individual batteries from which the battery is assembled) - this means that the battery is connected in series from 3 batteries, that is, the battery capacity will be 3000mAh, and the voltage will be 3.7x3 = 11.1V;
- 20C- discharge current (on a 3000 mAh battery means that the maximum continuous discharge current is 20*3000=60000 mA=60A).
Voltage
On batteries, instead of voltage, they write the number of cans.
The voltage of one bank is 3.7 V. Accordingly, 3 banks are equal to 11.1 V.
The number of cans is indicated by the letter S.
Discharge current
Denoted by letter C and a capacitance number.
For example, if the battery says 20C, and its capacity is 3000 mAh (3 Ah),then the recoil current is 3 Ah * 20 C \u003d 60 A
Peak discharge current
The current that the battery can give for a short period of time (which is also indicated in the specifications). Usually it is 10-30 s.
It is denoted in the same way as the discharge current, by the second number.
20C-30C means that the discharge current is 20C, and the peak current is 30C.Capacity
It is indicated in mAh (milliamp-hour). 1000 mAh = 1 Ah.
Charging batteries.
LiPo batteries are charged at 1C (unless otherwise indicated on the battery itself, recently they have appeared with the ability to charge with a current of 2 and 5C). The nominal charging current of the battery is 1000 mAh - Ampere. For a 2200 battery, it will be 2.2 amps, and so on.
The computerized charger balances the battery (equalizing the voltage on each cell of the battery) during charging. Although it is possible to charge 2S batteries without connecting a balance cable, we strongly recommend always connect the balancing plug! 3S and large assemblies only charge with the balance wire connected! If you don't connect and one of the cans draws more than 4.4 volts, then an unforgettable fireworks display awaits you!
The battery charges to 4.2 volts per cell (usually a few millivolts less).
Storage mode.
On a computerized charger, you can put LiPo into storage mode, while the battery is recharged / recharged to 3.85V per cell. Fully charged batteries will die if stored for more than 2 months (maybe less). They say that they are completely discharged too, but for a longer period.
Exploitation.
Discharging a LiPo battery below 3 volts per cell is not recommended - it can die. The engine controllers have the function of shutting down the engine when this condition occurs. We use s or . We also recommend using . It connects to the balancer connector and, as soon as it squeaks, it's time to land.
When the motor draws more current than the battery can supply, LiPo tends to swell and die. So this must be strictly monitored!
Now there are nano-tech batteries with a current output of 25-50C.
Preparation for work.
Preparing LiPo for use is very simple - just charge it and that's it! :)
This type of battery has no memory effect (no need to recharge before recharging), no need to cycle - do charge-discharge cycles before use.
If you charge in the field, then you should look for batteries with accelerated charging, they are written Fast charge 2C or 5C. In theory, they can be charged with a current of 33 Amperes!
The charger has a maximum of 5A, but this will reduce charging from 50 minutes to 20! (battery 1000 mAh)
