Restart the phone and suddenly battery has half of the juice!

http://forum.xda-developers.com – Hi all, as the description says it's quite weird. While I have let's say 56% battery and for some reason I restart the phone, then suddenly after booting it show I have 18%!!! (screenshot attached) Attachment 1288706 I have latest 4.0.4 official UK unbranded firmware and it happened on 4.0.3 too. I have tried factory reset and doing a battery cycle. Could it be a pure battery problem or may it be a bug? Anyone else has this problem? Sent from my GT-I9100 using xda app-developers app Attached Thumbnails   (HowTos)
