Help Sudden battery death

[MiklBjorn]

Hi,

I have had my S3 Mini for about a year. Now it has started dying suddenly.

It happens at irregular intervals, sometimes it happens just after finishing a 100 % charge, sometimes I can use the phone all day without issues.
Here is a battery-charge-level history of an event:

I cannot post it as a picure, as I am still a new user.

I think it may happen mostly just after accessing the web, but I am not sure.

Any thoughts?

Best,
Mikkel

i have the same problem. it's because the battery is half-damaged. try buy a replacememt battery.

while i use the phone and the battery was 80%. it just power off itself. i turn back on and the phone said that i have 1% battery left. i recharge my phone and reboot my phone, it said 54%.

Thank you for your suggestion. I bought a new battery (150 DKK, 30 USD) and it did indeed solve the problem
