Phone turn off when someone calling me

Try writing a lengthy text and try to send it to a friend to see if the battery slows things down or stop it altogether. A call would use more power and it's possible why it may be necessary to buy a replacement.

It may e soldered on to the circuit board but you would need to open the case to find out if it's that or it's removeable.

If it can support ten minutes of writing text or even playing music, there's nothing wrong with it and your problem lies elsewhere.

It works good untill someone calling me, or i call someone.
 
Six weeks later? Sounds like that battery needs replacing with a genuine new one.
