If your cellphone is being restarted at startup logo or shutting down automatically in your pocket you should first check battery connectors both cellphone’s and battery side.
Because of dust or due to touching battery on tongue by mistake. Some people thinks that they can test battery current by touching it on their tongue. But they don’t know they are actually destroying battery and terminals. So it should be a first reason of boot loop problem.

3- Faulty Battery:

In my experience as a cellphone technician, I have seen and fixed lots of smartphones with restarting  problem at boot logo by replacing or modify cellphone battery.

Why Mostly Smartphones Restarting on Faulty Battery?
Almost all smartphone batteries comes with self protection circuit. Some manufacturers using a resistor in series at GND line to protect battery from short circuit, over load etc. some times this resistor loose it’s resistance due to over heating. Then this resistor will not pass enough current to the phone, and phone starts rebooting on startup logo.

How to Restart Fault is due to battery?
In my experience we noticed that mostly phone stop rebooting while connected to charger. So if your cellphone is working fine during connected charger, and start rebooting immediately or in few seconds when charger being disconnected. It must be due to faulty battery or loose battery connections.


Solution!
Change your cellphone battery and you’ve done! If can’t change battery with new one then you can fix this problem by shorting big resistor used in series at GND line. Watch this video to understand.

4- Poor Hardware:

This is true that mostly LG phone users facing boot loop problem due poor hardware parts and logic board assembly by manufacturer. Boot loop problem is become famous from LG G3 series phones and later models.
