When the company was managed by Steve Jobs, Apple strictly followed his views and principles, one of which was a certain diagonal of gadget displays. So was the iPad, which, according to Jobs, was perfect and did not require changes. After Tim Cook got behind the wheel, and the market was already saturated with small tablets, Apple nevertheless decided to give up the principles of Jobs, and experts brought out their version of a mini-tablet. iPad mini was a real breakthrough, the device made a splash and forced many users to abandon the large iPad in favor of a more compact model.

Display
Unfortunately, the iPad A1455, being an experimental model, did not receive the latest technological advances and was left without the Retina display that was actively promoted on other devices. The resolution was only 1024 by 768 dots (163 dpi). Weak color reproduction and a dense air gap between the screen and the protective glass only exacerbated the situation. But users will be pleased with the oleophobic coating, which will not allow fingerprints to collect.
CPU and memory
iPad A1455 inherited the productive filling from the previous model (iPad 2). The heart of the tablet is the proven Apple A5. The chip has two cores and a clock speed of 1000 MHz.
Memory capacity is also similar to what we have already seen in the second generation iPad.
Battery and camera
iPad A1455 received a smaller battery (due to its size), but a more advanced camera (such as was installed in the iPad 3). The operating time remains the same, standard 10 hours.
As for the software component, then everything is not too good. The iPad A1455 received a lot of updates and was supported by Apple for quite a long time, but the very first update brought its performance to a critically low position. The frame rate dropped, the battery life too, almost all the functions from the new ones were cut.firmware. In general, you should use the tablet only on the original firmware (iOS 6).
About the prices. Now the device is no longer for sale, but a new one would cost around 15-20 thousand, a used one can be purchased from 7,000 thousand rubles, which is quite democratic, but hardly worth it.
Battery problems
Due to the fact that the device is already quite old and probably in the hands of the owners, there may be a problem with the battery. This can be either inevitable wear and tear (a large number of recharge cycles), or damage by a bad charger, right up to disabling the gadget.
If you are sure that the problem is in the battery, your iPad A1455 is not charging, then you should contact the workshop or technical center where you will have it replaced. Otherwise, you can try your luck and try to open the iPad and replace the battery yourself.
iPad mini A1455: battery disassembly and replacement
Apple technology is quite complicated, the manufacturer does not recommend self-repair of its devices, therefore it makes it almost inseparable, and all modules are glued tightly. If you still decide to take such a daring step, then here is an instruction on how to do it all.
First, you will need:
- Watch screwdriver, pentagon (Apple uses Philips 1).
- Hair dryer
- Plastic card or pick.
- Tweezers or tweezers.
The first thing you need to get rid of is the display, since the back panel is not removable, and there are no bolts on it. To make itto do, it is necessary to warm up the display to a sufficient temperature so that it begins to slowly move away from the main panel. Once this has happened, use a pick to pry off the glass, slide it around the perimeter, carefully separating the screen.
After removing the glass, you will have to unscrew the display panel. A screwdriver will help us here, carefully unscrew all the bolts under the plugs and continue. Even after this step, a number of difficulties await you. The fact is that the screen is attached to the motherboard with a cable. Carefully pry and lift the steel plate, unscrew part of the motherboard. After that, you need to pry off the display cable with a pick, but first peel off the pieces of electrical tape (here we remember the tweezers), carefully attached by the team of assemblers at the manufacturer's factory.
If you completed this task without breaking anything, you can put the display module aside and work on the battery, which is now freely available.
With the battery, everything is much simpler, you can pry it with a pick or a plastic card (everything is held on with glue and adhesive tape) and just remove it, after disconnecting another cable.
Before installing a new battery, make sure it is suitable for your tablet. The ideal option would be the original (possibly a donor battery), but Craftmann products have also proven themselves well.
Since the battery on the iPad mini is much less protected than on other models, it will be enough to correctly put it on the glue and correctlyconnect the cable, then replace the display module.
Instead of a conclusion
It's worth being very brave, well, or well enough versed in Apple technology in order to proceed with the self-repair procedure. Any tampering on your part will void your warranty, and damage to important parts will require the replacement of almost all components. So, if you still decide to do it yourself, disassembling the iPad A1455 is done at your own peril and risk. Be extremely careful and careful. And think carefully if the game is worth the candle.
