Most modern smartphones are equipped with a non-removable battery. This design has a number of advantages over collapsible devices.
The built-in battery significantly improves the performance of the device:
- Dimensions. The thickness and weight of smartphones are constantly decreasing. Devices are becoming more ergonomic.
- Durability. The less access to devices is given to users, the more the likelihood of breakdown due to external interference is reduced.
- Hull strength. The non-separable design allows the use of high quality materials such as glass, ceramics, specially processed metal without the risk of deforming the back cover.
- Tightness. Most monolithic devices are IP protected. The non-separable design allows you to make dust and water resistant devices.
Of all the advantages, there are also disadvantages:
- Inability to replace the battery or a broken connector by yourself without using special tools.
- The high cost of repair.
If the owner nevertheless decided to make repairs on his own, then it is necessary to clarify how the device is disassembled and which part is needed.
Replacing the battery yourself
First of all, you need to stock up on such tools:
- Sucker. The fixture is fixed to a smooth surface allowing the panel to be removed.
- Screwdriver set for loosening bolts.
- Tweezers – essential for delicate work.
- Special plastic crowbars. The material does not allow scratching the case during operation.
- Remove all possible elements – SIM cards, memory cards, trays, plugs, etc.
- Detach the back panel. To do this, carefully pry off the cover and remove it with a suction cup.
- After that, you need to use a screwdriver. Remove the additional cover plate.
- The next step is to disconnect the battery. It is necessary to carefully examine the insides to determine the location of the power cable.
- The battery can be attached with an adhesive. For neat removal, you need to use a plastic tool.
- Install a new battery.
- After installing the loop in place, you can briefly turn on the device to test the power.
- The assembly takes place in reverse order.
When attaching the rear panel, do not apply much force – this can break the geometry.

How to restart a frozen smartphone (without removing the battery)?
If the device refuses to work, shows the user the boot logo or the same picture without responding to any actions, then it must be rebooted. In most cases, holding down the power button for 20-30 seconds helps. If this option does not help, then you should try one of the combinations:
- Power + volume down.
- Power + volume up.
- Power + volume up + volume down.
The combinations should force the device to reboot. If the procedures do not help, then all that remains is to wait for the complete discharge and then connect the device to the power supply.
The most common cause of freezing is software glitches, installed applications, or overflowing memory. A possible solution would be to start the device in safe mode and delete files, or reset to factory settings.
