I just got a galaxy s3 for a few months now, it worked fine. So i decided to root my phone, but shortly after rooting i regretted my decision and unrooted my phone back to stock because everything was too confusing. After a few days i noticed massive battery drain, so i kept it charging, but it drained even when charging. So i decided to drain the phone to 0 and charge it to 100. When my phone was completely drained and i plugged in my charger, and the battery indicator changed to 50% or so. So i let it charge to 100. I used my phone when it was 100% but when it hit 30% my screen started flickering and my phone froze so i had to pull out the battery and it went back to 0%. I thought it was a battery related issue so i replaced my battery with the same original one and the problems still occur. I hope this is enough information and i hope you guys can help me.

Thanks in advance :)
Hello there and welcome florisvengelen;)

I understand your eagerness to resolve your issue, and that drain can be quite frustrating, but no need to bump the thread after a relatively short period of time. It's the weekend and generally the forums are less active then;)

Anyway, just curious what method you used to root, then unroot.
After unrooting, did you do a factory reset?

Sorry for that, i can be a bit impatient.
I used odin to root, because the easy method didn't work because i had a different kernel or something. I did a factory reset twice now
ok, no problem.

Roughly how long does it take your device to discharge from 100% to 30% with the new battery? And also, how are you using the device? (browsing, streaming, texting, phone calls etc)
What does your battery usage screen say is using the battery?
Here's my battery screen on 20% it's dutch so i hope you understand

So, in about 5 hours, your device went down to 20% correct?

How many charge/discharge cycles has the phone been thru?

I have to step out for a few hours, but I'll try to circle back here.
What do you mean by that?

I let this battery drain and charge to hundred percent, but it starts at 50% so basically not 100%
No, that's not the problem. My phones shuts down when it's empty but when i connect the cable when it's off, it fills to 50%
Well, no solution i guess.:(

Try a factory reset, if that doesn't work reflash the firmware from sammobile, and if that still doesn't work, try different cords/batteries, and if that still fails, tell Samsung about your problem, though I doubt they'll do much since rooting kills your warrenty...
