How to fix an Android phone that automatically goes off or shuts down frequently

One pretty annoying experience is a mobile phone suddenly
going off on you, especially when you’re working on a
document, article or doing something really important;
something you were careless enough not to have saved.

we’ll be taking a look at this same issue on
Android phones, a commonly ignored ‘suicide note’ to you
from your smartphone.

What could cause an Android phone to automatically go off
or shutdown frequently?


The most common causes of this issue are:

Damaged battery: The battery of the phone might be
swollen or damaged

Overheating: The phone might be overheating due to a
hardware or software issue, causing it to shutdown in
order to cool

.Rogue or incompatible applications: An incompatible
application (usually apps that require root permission ;

could be causing the OS to crash


Incompatible ROM or buggy update: Flashing an
incompatible Stock ROM, Custom ROM or a
buggy / unstable OS update could be another factor


Faulty hardware: The phone might actually have been
sold with a factory defect or have developed a board
issue


Loose battery connectors: The battery might be getting
unseated during movement due to loose battery
connectors

Damaged SD card: The memory card might be
damaged or corrupted

How do I fix an Android phone that automatically goes off
or shuts down frequently?

Terminate unneeded apps / processes: Ensure to close
applications or processes not in use like WI-FI,
Bluetooth, GPS etc so as to reduce the workload on
the processor and battery
Format the memory card or try using another one

Avoid overcharging the battery: A battery should have
charge-discharge cycles, not charge-overcharge cycles.
Overcharging could make the battery wear out quickly

Uninstall buggy apps: If the phone begins to shutdown
suddenly, freeze or becomes slow shortly after installing
certain apps then uninstall them

Revert to the previous ROM: If you recently flashed
another ROM or did an Android OS upgrade then
consider reverting to the previous version. In some
cases, re-flashing the Stock ROM or doing an OS
upgrade resolves this issue

Avoid overheating: Poor maintenance practices like
setting the screen brightness too high, placing the phone
near hot objects, using the phone heavily while charging,
charging the phone using a PC and a USB cord
etc should be put in check


Adjust the battery connectors: The battery connectors
transfer charges from the battery to the board and also
help seat the battery firmly in place (you should see them
protruding from the phone once you take off the back
cover and remove the battery). Use a non-corroded
metal to gently push them in place if they appear loose


Replace the battery: Check to see if the battery is
swollen or not charging properly to be sure the battery
is actually the problem. If it is, then consider a battery
replacement


Consider returning the smartphone: If the phone is
brand new and still under warranty then you should
consider taking it in for replacement or repairs before
voiding your warranty by dismantling or rooting the
phone see( http://www.gistpluz.com/2015/06/tutorial-on-how-to-root-all-tecno.html
