Help Battery suddenly drops charge by significant amount randomly?

[Cutless009]

So the other day whilst using my phone, it locked up for the very first time. Fine, whatever. Reset the phone no biggie. I was at 89% battery when it died. Upon reboot I found that I only had 54% charge. Really? In the time it took to reboot the phone? Wierd... Until now I just wrote it off as a fluke as it never happened again.

But it just did. Lockup/crash, phone reset, charge goes from 51% to 32% in the time it takes to reboot the phone.

What the hell?




First crash:
Midnight Rom 2.2
Zedomax Kernel

Second Crash:
Midnight Rom 2.2
w/e kernel comes with the midnight rom (I can't seem to find the name at the moment, but it isn't zedomax).

Stock clock speeds.

This is a known issue with Samsung phones not accurately determining the phone's actual battery charge. Happens to me from time to time on a variety of roms, and as far as I know there is no real solution. Regardless, I would try using the app Battery Calibration from the market.

+1 its a Samsung thing! I hate this glitch, your not alone. Its truly a good thing this phone doesn't freeze up frequently. I've noticed its an avg. Of a 20% batt. Loss, only rebooting the phone when needed, I usually hold down the power for about 10 secs. This brings up an auto reboot that doesn't seem as severe as battery pulls & power offs.

Mine did that too until I calibrated my battery. Only little problem now is when fully charged I will take it off the charger and it drops to 97% in seconds is this normal?
