5. Mainboard damage
Another possibility is the mainboard.
Q: What is the mainboard?
A: The mainboard (motherboard) is the core part of the hardware and controls all functions of the phone. Every part of the phone with a function is connected to this mainboard.
Q: How can the mainboard gets damaged?
A: The mainboard can get damaged from shocks (drops), dropping into water or even from pressure. It can also be caused by charging with a poor quality charger/cable. Damage to the mainboard can arise even if there is no physical damage.
Q: What happens when the mainboard is damaged?
A: As the mainboard is the core part of the device, once it’s damaged, it can make functions play up. The functions affected depend on the location of the damage.
Q: How do I know if the battery life is draining quickly because of the battery itself or mainboard damage?
A: There is no way to physically find out if the mainboard got damaged or not unless you test the device with a new battery and see if it is working or not. With this matter, we can help you through a quick inspection and can tell you if it will be solved by replacing the battery or not.
Q: What should I do if it is a mainboard damage?
