Is anyone having problems with their Samsung Galazy S II? My phone shuts down and the battery is fully charged & after phone shuts down I try to turn phone back on & receive message battery critically low.After this happens I charge phone & battery status shows battery half charge.
So sorry that you’re having issues with the phone! I would suggest you to visit our Sprint Service and Repair Center to have your device, battery and charger cable checked.
I have the same issue as well. It doesn't matter if the phone is at 75, 50 or 30% after the shut down, it comes back at 1% each time. I have tried reseating the battery and cleaning the contacts, no luck. I charge from 3 different sources, doubt its any of the chargers. I actually ordered an extended battery from Amazon trying to kill two birds with one stone. I will keep you posted if it resolves my issue.
Also this issue was occuring before and after I updated to ICS, so its definitely hardware related. The occurance is really random. I had it happen 3x last week, this week I have used it 5 consecutive days without it happening.
