Guys, another possibility is that the charger is not fully charging the battery! (even though it says its fully charged).I`ve charged the phone up, the device was fully charged.Then I`ve surfed for 4-5 minutes through wifi, and the battery was discharged just a little bit....then I plugged the phone again and it started charging for at least 30-45 minutes more, even though the battery was fully charged?This is strange!
