    Ever since I updated to 10.2, my battery drains significantly quicker than it used to. This is on an iPhone 6 Plus.

    Any ideas what could be causing this? Is there a setting I need to change?

    I have the same problem for iphone 6. After the update my battery drains very fast and my phone shuts down even when my battery is 30!! I have read in some forums that it is not about the battery but it is a software problem and restoring device as new solves this problem. I did not try it yet but would appreciate feedbacks if anybody did..

    Firstly, You need to log out unnecessary app platform, clear kinds of software cache.
    It's better not update the high level, Google how to downgrade back.
    Secondly, in order to prolong the battery lifespan, it's better not charge it to 100 percent nor drain it to 0 percent, 40-80 percent is a good guideline.
    Good luck:)

    Agreed. Clearing the cache is critical. Which most seem to forget to do. Good point.
