Lately, well it's been quite a while actually... my battery stats seems to jump whether i'm charging or discharging.
While charging sometimes it jumps from 30% > 80% > 100% within 15 minutes (this is what happened today) while discharging, it jumps from 90 > 50 (this quite often) then to 20% > 5% then off. My max usage time without charging is usually less than 1 hour.
I've tried to do battery reset (charging while the phone is off until full, reset battery data, then use it till it 100% drained)
I've tried to charge from 30% to about 80/90% then use it as usual.
I used original charger from motorola, used blackberry charger, samsung charger, no difference.
Unfortunately no good. Currently the ad hoc solution is to use battery powerbank constantly while I'm not near electrical plug. But its bulky and well not the best solution.
My question is, does the problem lies in the battery or at the battery controller. Is there anyway to test where the culprit is?
Thanks in advance
