My battery on my Alcatel Onetouch Idol S (running Android 4.2.2) is behaving oddly. It will discharge normally, then all of a sudden go from 55% to flat (0%) in seconds. I would put it down to finally rooting it, but I have no cold evidence to prove it. Does anybody know how it can be fixed, or how to figure out why it is happening?

Additional info:

  • I believe the CPU governor should be set to ondemand
  • It was rooted via KingRoot v4.6.0 132, and the KingRoot kernel version is 4.6.0 47
  • The SU version is 3.54
  • How old is your battery? You can try the steps in accepted answer here and then my solution, android.stackexchange.com/questions/128091/…

  • @beeshyams The battery is about a month old. Literally a month. Oh, i will try the second method on that link, but it is the only one i can do at home. There is a irremovable back (though the manufacturers can take it off)

  • @beeshyams It worked, kinda. My phone did not turn on. Charged it to find it was drained, and it had a normal discharge when booted. I done that about a day ago.
