How to start using a new battery?
Before using for the first time, the lithium battery must be charged! Only new Ni-Cd (nickel-metal cadmium) batteries are discharged before use, and lithium batteries need to be charged!
Do not leave the battery discharged, immediately put the device on charge. These cycles are necessary for your device to use the full capacity of the new battery.
How to extend battery life and run time?
It must be remembered that the service life and operating time of the battery is reduced when:
One of better ways checks.
There are several various ways status checks iPhone battery and iPad. The most accurate of these, using the coconutBattery application, requires the user to have Mac computer which, of course, many do not have. Fortunately, you can check the battery status most accurately on computers under Windows control, and completely free. This guide explains how.
Most users check the battery status through the Battery Life app from App Store. It is really convenient and simple, because to perform the check it is enough to download free app from the store, spending only a couple of minutes to check.
Work example life applications battery.
However, apps like Battery Life often get a lot of negative feedback that the verification is not done correctly. The application, for example, shows that the remaining battery charge is at a critical level, when in fact this is not the case. The most embarrassing thing is that such applications show different results with each check, and the indicators vary very much, which, of course, cannot be.
Because of this iPhone users and iPad, it is highly recommended to check the battery status of your mobile devices using special utilities for computer. On a Mac, this program is coconutBattery, and on Windows computers, iTools or iMazing. In both cases, the verification is absolutely free.
Step 1: Download the iMazing utility from official website of the developer. Install and run the program.
Note that iMazing asks for activation after launch - it is not required, since the battery status check function we require is available completely free of charge. On the given request should press " Later».
Step 2: Connect your iPhone or iPad to your computer using USB cable. The device will be detected in iMazing. If this does not happen, then this means that your iPhone or iPad was not previously detected in iTunes. You need to launch iTunes and allow mobile device trust your computer.
Step 3. On the device page, click on the battery icon.
Ready! The window that opens shows Technical information about the battery of your iPhone or iPad. Pay attention to the line " Maximum effective charge“, which indicates the remaining capacity of the battery in numerical and percentage terms. Important! If your iPhone or iPad battery is old enough, for example, its residual capacity level is 85 percent or less, then the indicator in the “Maximum effective charge” line in iMazing and iTools will jump, this is due to chemical characteristics lithium-ion batteries. However, the differences will be about 1-2%, which will make it possible to get an understanding of the real state of the battery.
iPad 2017, or, as it is also called, iPad 9.7, is the direct successor to the Air line. The introduction of a new, more advanced device into the market inevitably leads to a drop in demand for previous models. Apple decided not to wait for the drop in sales iPad Air 2 and "killed" the line. Now officially on the company's website you can only purchase iPad Pro(with 9.7" and 12.9" screens), iPad mini 4 (7.9") and unnamed iPad.
Equipment and design
Apple branded solutions meet the user already at the unpacking stage: a pleasant matte surface of the box, a familiar design, a traditional set and arrangement of components. In addition to the tablet, the kit includes a charging hub, a Lightning cable, an insert with tips and two stickers. No paper clips: participates in Lifehacker's review iPad WiFi, which does not support the use of a SIM card.
The case of the new iPad repeats the first iPad Air to the nearest millimeter. Device dimensions - 240 × 169.5 × 7.5 mm. The weight is the same as the 2013 tablet at 469g and 478g for Wi-Fi and Wi-Fi + Cellular respectively. The only external difference from the iPad Air is that the mute button, which was lost during the production of the iPad Air 2, was not returned to the new iPad. Well, the speaker holes are now arranged in one row, as in the iPad Air 2.
iPad Air 2 on the left, iPad on the right. Such decisions are not new for Apple: something similar happened last year when the company presented the iPhone SE - iPhone 5s with an improved and more modern "stuffing". Such an upgrade of time-tested devices can significantly save on the cost of the final product, which ultimately affects the price for the buyer. Borrowing previous technological solutions gives users another non-obvious plus: cases for iPad Air, iPad Air 2 or iPad Pro 9.7 will fit the new iPad.
For those who have not dealt with Apple tablets before (what if!): on the top edge of the aluminum case there is a headphone jack (3.5 mm) and a lock / off button, in the upper part of the right side there are volume keys, in the center of the bottom facets - Lightning input for charger, surrounded on both sides by speaker holes. Bottom - home button, the only mechanical key on the front of the iPad. All buttons look beautiful and respond nicely to pressing.
The new iPad is available in three colors: silver, gold and space gray. The rose gold version is only available on the iPad Pro line.
Screen
Nothing new. In principle, many of the points of the review can be started with the words "nothing new". And that's not bad when it comes to the price of 24,990 rubles.
The new iPad received a 9.7-inch touchscreen Retina display with a resolution of 2,048 × 1,536 pixels and a density of 264 ppi - a similar screen is also available on models of the iPad Air line and the 9.7-inch iPad Pro.
On the way to an attractive price, Apple has stripped the new iPad of some of the features present in more expensive tablets. The iPad 2017 lacks True Tone, which adjusts display colors to match ambient light. Also, the new iPad is not equipped with an OGS display, that is, there is an air gap between the screen glass and the matrix, as in the first iPad Air.
Battery
The battery capacity has increased to 8,827 mAh. For comparison, the battery of the iPad Air 2 boasted only 7,340 mAh. Despite this, Apple traditionally claims ten hours for the new iPad. offline use. We suspect that this nuance is due to the power consumption of the A9 processor.
Features and performance
The main advantage of the iPad over the iPad Air and Air 2 is the 64-bit A9 processor. It's not the best powerful processor Apple: Pro-series tablets have A9X, and iPhone 7 has A10. Volume random access memory- 2 GB.
Greetings! There can be many reasons for the need to check information about how much capacity is left in an iPhone or iPad battery. Such a need may arise from simple curiosity: for example, it became interesting to me - do I need to go and change the battery of my old iPhone 5S? Or is she not that bad?
Also, great importance a similar procedure is acquired during the purchase of a used device. After all, the seller can simply deceive - to say that his battery holds exactly as much. And even show usage statistics (it can be easily cheated), but in fact - half of the capacity has already been lost there. How to find out the truth about the condition of the battery - is it bad or not? No one will wait several hours to check! There are ways easier and faster - we'll talk about them, let's go!
Important note. We get all data about the battery for free, without hacking the device and other jailbreaks. Cool? Not that word!
Now we're really starting. Forward!:)
How to check the battery life of an iPhone or iPad using a computer?
There are many programs that can give us all the necessary information about the battery. These are the famous iTools, iFunBox and many others. However, they are crammed with various functions (sometimes very redundant), and we only need battery statistics! Therefore, in this case, I advise you to use iBackupBot - the desired function in it is also not the main one, however, the minimum size of the program and a simple interface speak in its favor.
You can download it from the developer's website, there are versions for Windows and Mac OS. Please note that iTunes must be installed to use the program.
Since all the inscriptions on English language, I will give a small transcript of the data received:
- CycleCount - the number of complete recharges of the battery.
- DesignCapacity is the capacity that the new gadget originally had.
- FullChargeCapacity - capacity for this moment.
- Status: Success - the general characteristic of the battery at the moment.
As you can see, my iPhone 5S lost only 150 mAh capacity in 2.5 years, and this is a very good result! In fact, it's almost brand new. How did he manage to achieve such indicators? I just know how, try it and you - there is nothing complicated there.
Applications that will tell you everything about the battery status in iPhone or iPad
Unfortunately, no one is immune from the situation when the computer is not at hand, and you need to check the battery life of your iOS device here and now. Various applications from the App Store can help us with this. The best part is that you do not need to hack the device and install a jailbreak - everything happens without it.
While writing this article, my iPhone has been visited by a huge number of programs (about 15-20) in one way or another related to the battery. And only in one of them all the data (charge cycles, actual capacity, etc.) were shown for free, immediately after installation and without any additional purchases.
Meet Battery Life. Download link in the App Store. Install and run. Click in the upper left corner - the settings open, we are interested in the menu item - Raw Data. And we clearly see all the information (also displayed in real time!).
A few points:
- Battery Charge - the indicator means how much the battery is now charged and how much it can be charged as much as possible.
- Capacity - current\standard battery capacity.
- Cycles - number of recharge cycles.
The attentive reader will notice that the data for my device is slightly different in various checks (using a computer and an application). How so?!
Firstly, this difference is really small - the error is 3-5%. And secondly, this is completely normal - since different programs use different algorithms. And besides, the battery of my iPhone 5S has been working for quite a long time - almost 2.5 years, and it is quite difficult to analyze its use over a similar period.
In any case, the check can be carried out by any option presented in the article, and the overall picture of the battery life of your iPhone or iPad will be clear. To get the most plausible values - use both methods, and choose the average of what happened.
Fans are waiting for the release of each new model of Apple tablets with special hope, because these are new “chips” and more opportunities for users. So the release of the iPad 3 model was marked by the appearance of the latest Retina display, which at that time was distinguished by incredible image quality. I wonder what pleased the developers in the new iPad 4 model?
The appearance of the gadget has not changed much, which noticeably pleased fans of the Apple brand. After all, according to experts, the case of the iPad 3 was recognized as the most optimal.
The only external difference from the previous model was a smaller Lightning system connector, which replaced the traditional 30-pin dock connector.
The dimensions of the tablet, as before, are 241.2 × 185.7 × 9.4 mm with a mass of 652-662 g (depending on the presence of a cellular communication module). Maybe some users were expecting a smaller size from the new model, but let's remember the increased capacity battery, which mainly affects the thickness of the device.
The front panel of the tablet is closed protective glass with an oleophobic coating that reliably protects the display from accidental bumps and scratches. The lens of the new 1.2-megapixel front camera is mounted above the screen, below it, as before, there is a hardware Home button. Apple developers deliberately left the matrix bezel wide enough, which makes it possible to comfortably hold the case without touching the touch screen with your fingers.
The rear panel is made of anodized aluminum, which, together with smoothly beveled side faces, is a single piece. On its upper end there is a power button, a headphone jack (3.5 mm) and a black antenna plug mobile communications. The lens of the main camera is built in next to it. A speaker and a Lightning connector are built into the bottom of the rear panel.
On the left side of the case there is a Micro-SIM slot (relevant for a model with 4G), on the right - a rocker key for volume control and a "Mute" slider, which also blocks automatic image orientation.
Screen
In tablet Apple iPad 4, as in the previous model, a Retina display with a resolution of 2048 × 1536 is used. With a screen diagonal of 9.7 inches, the pixel density is 264 PPI, which makes the image on the screen more like a glossy magazine page. The pixels are completely indistinguishable, so the reality of the image is simply amazing. This time the developers have made right choice. Why look for other solutions if this display is considered the best among all 10-inch tablets. The only drawback is the lack of anti-reflective coating, which has been discussed a lot by users of Apple gadgets.
The IPS-matrix is made using the same technology, therefore it combines natural colors and maximum viewing angles. Its quality is especially noticeable when compared with previous generations of displays. The positioning of the capacitive sensor has become more precise and, in addition, it has a warm color gamut with improved image detail.
Speed and functionality
If we talk about the main differences between the iPad 4 and iPad 3 models, then they are more related to their filling. The new tablet uses a processor with a clock frequency of 1.4 GHz - Apple A6X. The quad-core PowerVR SGX 554MP4 with a performance of up to 76.8 GFLOPS is used as a graphics coprocessor. An interesting fact is that the leading Android models contain up to 17 cores in the graphics system. Despite this, their performance is several times inferior to Apple tablets. 
The new solution was the placement of RAM. It is moved outside the processor chip and implemented on two chips of 512 MB each, that is, the total capacity is 1 GB.
Permanent or flash memory is installed with a capacity of 16, 32 or 64 GB. For the model released in January 2013, it is 128 GB.
There are three options for communication blocks for the new tablet. Two of them can be used to transfer data via cellular communication type 2G/3G/4G, but they cannot work in our CDMA/EVDO networks and do not support domestic LTE frequencies.
Camera
The iPad 3 uses an outdated 0.3 MP VGA model as a front camera. In iPad 4 model front-camera has a resolution of 1.2 megapixels and supports shooting videos in 720p HD quality. Of course, it, like the previous one, is designed only for FaceTime communication, but the picture quality has become much better.
The main iSight camera has not undergone any changes. It also has a resolution of 5 megapixels and supports shooting 1080p/30 fps HD video with image stabilization. At the same time, high definition, color reproduction close to real, autofocus, tap focusing and face detection are supported. 
Nutrition
The new Retina display and hardware capable of supporting high-resolution graphics have resulted in increased power consumption. This also forced the developers to significantly increase the battery capacity even in the iPad 3.
Like its predecessor, the iPad 4 uses a 3.7V 11560mAh (43Wh) lithium polymer battery that is only 0.6mm thicker than the 25Wh batteries. This innovation still keeps Apple tablets in the lead in terms of battery life.
See for yourself, on a single charge, the iPad 4 tablet allows you to watch videos for up to 10 hours, listen to music or audio books for 140 hours, or stay in a state of waiting for a whole month. It's hard to find similar figures among other models, given the graphics quality and system performance.
As mentioned at the beginning of the article, the tablet uses a miniature 8-pin Lightning interface, which is almost 80% smaller than the outdated 30-pin one. Now the connector has become fully reversible, so you can not be afraid to insert it the wrong way.
