Battery is insanely draining. Earlier it was working fine for 3 or 4 days, then suddenly it was not charging up to 100% and discharging rapidly in few minutes. I have tried to charge more than 3 hrs but no use. its going to 1% and switching off and showing more than 30 -70% when ever I keep charging in off mode.
I have checked with re-sellers support, they have suggested that firmware update will resolve battery issue. I have updated firmware from cxq_v3_v1.0.6T02
. after updating firmware now mobile is charging to 100% but immediately with in 1 or 2 hours, some times in few minutes its going to below 4% and switching off. some times it will charge to 100% with in 30 min.
I have checked battery with multiple battery calibrate apps and find no issue, all are showing healthy and good status. There is no Physical change in appearance/size in battery (like expanding in size). its good as new one.
This is Android software problem or Battery problem ?? can some one please help me or suggest me anything??
