Recently my G2 has started dying whenever I use it for more than 5 consecutive minutes. When I reboot it I need to plug into a power source or it will not reboot and it reports that I have 0% battery even though I actually may have 95% or more. Removing the battery does not help - only a 5-minute wait period - could it be some overheating issue? It does not feel warm to the touch. If I leave it off for about 5 minutes and reboot it, it then correctly reports battery life. I have had this phone since September 2010. I am running Gingerbread 2.3.4. Has anyone else experienced this?

I'd try getting a replacement battery. For less than $20, you either locate your problem or have a spare battery. –  BMitch Mar 13 '12 at 21:00

It is possible that the problem is in your battery more precisely in battery controller.

There are a few possible solutions:

  • Try recalibrating your battery.
  • Try removing /data/system/batterystats.bin.
  • Put somebody's battery inside (if you know somebody with the same model) and look how phone works. If it works fine with somebody's battery then just buy new one.

Thanks for your response - how do I recalibrate the battery? –  Davn8r Mar 14 '12 at 1:26
    
Also my /data folder is empty –  Davn8r Mar 14 '12 at 1:33
    
myhtcdesire.com/tutorials/… . There are some more tutorials in internet. All those tutorials propose to make a couple charge-wait-boot cycles. I had some issues with my pocketbook`s battery but I solved it by charging and resetting my device in random order :|. –  Alex Bolotov Mar 14 '12 at 21:41
    
Install JuicePlotter from latedroid.com to see what happens to your battery –  Alex Bolotov Mar 14 '12 at 22:15
