When the company was run by Steve Jobs, Apple strictly followed his views and principles, one of which was a certain diagonal of displays on gadgets. 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 full of small tablets, Apple nevertheless decided to give up the principles of Jobs, and experts brought out their version of the 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 a Retina display, which was actively promoted on other devices. Resolution was only 1024 by 768 pixels (163 dots per inch). Weak color rendering and a dense air gap between the screen and the protective glass only exacerbated the situation. But users will appreciate the oleophobic coating, which will not allow fingerprints to collect.
CPU and memory
iPad A1455 inherited a productive stuffing from the previous model (iPad 2). The heart of the tablet is the proven Apple A5. The chip has two cores and a clock frequency of 1000 MHz.
The amount of memory 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). Opening hours remain the same, standard 10 hours.
As for the software component, then everything is not too good. iPad A1455 received a lot of updates and was supported by Apple for quite some time, but the first update brought its performance to a critically low position. The frame rate dropped, the operating time from one charge, too, cut down almost all the functions of the new firmware. In general, using the tablet is 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, used 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 both inevitable wear (a large number of recharge cycles), and damage by a bad charger, up to the incapacitation of 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 be replaced. Otherwise, you can try your luck and try to open the iPad and replace the battery yourself.
iPad mini A1455: disassembly and battery replacement
Apple technology is rather complicated, the manufacturer does not recommend self-repairing its devices, therefore it makes it almost inseparable, and all modules are glued tightly. If you nevertheless decided to take such a daring step, then here is an instruction on how to do all this.
First, you will need:
- Pentagon screwdriver (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 cannot be removed, and there are no bolts on it. To do this, you need to warm up the display to a sufficient temperature so that it starts to slowly move away from the main panel. As soon as this happened, use the pick and pry off the glass, run 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 by a cable. Carefully pry up and raise the steel plate, unscrew the part of the motherboard. After that, you need to pry the display cable with a pick, but first peel off the pieces of electrical tape (here we recall the tweezers), carefully attached by the team of assemblers at the manufacturer's factory.
If you coped with this task without breaking anything, then you can put the display module aside and take up 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 by glue and duct tape) and simply remove it, before disconnecting another loop.
Before you install a new battery, make sure that it is suitable for your tablet. The ideal option would be the original (possibly a donor battery), but also the products of the company Craftmann have 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 correctly connect the cable, and then return the display module to its place.
Instead of a conclusion
It’s worth it to be very brave, or to understand Apple technology well enough to start the process of self-repair. Any intervention on your part will result in a loss of warranty, and damage to important parts will require the replacement of almost all components. So, if you still thought of an independent repair, disassembling the iPad A1455 is done at your own peril and risk. Be extremely careful and careful. And think carefully whether the game is worth the candle.
