Battery life drops from 40%-0% in seconds

[Jake McCann]

Hi all,
Thanks in advance for any advice or help.
So for a little while now my battery life has been a bit weird. Its got to the point my phone will drop from 40% or around that to dead in seconds. I gave had the local phone shop replace the battery twice (with genuine batteries), and nothing changes. It is worst when I go to bed with anything around 50% battery and put my phone on airplane mode like I do every night. When I turn airplane mode off and start using the phone it dies within a minute. I've taken screenshot of the battery monitor too.

Can you post the screenshot please? It really does sound like a battery issue, but if you are having the same issue after 2 replacement batteries, I would start to question a motherboard fault. Install accubattery app and see if that can give you any info about the battery, even though it is a replaced one. But I do think there might be other hardware failure going on.

OP mentioned that the battery has already been replaced twice at a repair shop.:-\

And that's what happens when you in so many threads

Probably some hardware issue that needs a repair shop then
