Short story: I bought a S4 Mini GT-I9195 second hand and the battery meter goes up and down like crazy. Thought that flashing Android 4.2.2 will solve this but couldn't do it (auth error in Odin). Rooting seems soo complicated.
Question: Is it possible that the battery meter issue will be fixed if I root/flash a different ROM?
Long story:
I had in the past a device with Android 4.4.2 (Allview brand) and the battery would drop many percentage points in seconds after several hours/days of what seemed to be normal usage. Now, the same happens with S4 Mini, and this made me believe there's a possibility I can make this phone usable by downgrading to KitKat, since I already have a device with 4.2.2 that works great regarding battery readings.
In more details, the issue is that the battery lasts up to one week if I am not touching the phone. The chart (GSam Battery Meter) shows a steady level decrease. When I use the phone however, there comes a moment (ususally around 40%, but not necessarily) when the battery level drops with 1% every 10 seconds.
It can go from 20-30% to 0% in minutes. After I plug the phone, the battery starts charging from 30-40%.
After unplugging at 100%, usually it goes straight away to about 90%.
I have tried already to clear cache, format the battery, so on. I have also tried to flash 4.2.2 with Odin, but it won't take any other ROM then the latest.
If rooting, and risking to brick the thing, wouldn't do anything to solve this issue, I may be better selling as it is, while it is still working at least. Otherwise, I can't use this phone!
Thank you for your help!
