    Try clearing Cache and also wipe Out cache through recovery mode by opting for recovery mode in developer option. This may be helpful for you.

    that looks like a wake lock if I have ever seen one. do what the other person said, clear the cache or factory reset. if that doesn't help then it's gonna be an app causing it.

    Factory reset only wipe data and cache, if is an app that drain your battery you can uninstall yours app one per time and look at the battery behavior, the best way is the follow
    Go to settings-app
    Select one app, delete all data app, kill and then uninstall. Do this one app per time and probably you will found the culprit

    Enable adaptive display.

    This can be enable inside display tab of setting option and if close the unnecessary application which you are not using These as well consume battery in the background.

    Will remove cache memory occupied by various apps which usually occupy space in RAM

    I'm facing a similar problem on my OP3. notice the rise? that's when I put it on charge and let it update. after the update, see the drastic drop in battery. "Android system" was never even in the top three most battery draining reasons, now it's right there on top.

    Just posted this in 2 other similar threads, re-posting it here in hopes that it might help someone else:

    So I tried something recommended on another forum and it worked for me (I was at 100% wakelock going from 100% battery to 75% after only about 10 minutes of screen on time over the course of a few hours, all since upgrading from 4.0.2 to 4.0.3).

    I went to Settings -> Apps, 3 dots at the top right, "Reset App Preferences". This will reset default apps but the important piece is that it revokes permissions from 3rd party apps. Reboot afterwards.

    It takes a little while to "kick in", ie I noticed that when I went into apps immediately afterwards they still seemed to have their permissions, but after about 5 minutes when I went into Whatsapp (for example) I had to re-grant it access to Contacts, etc. You'll have to re-grant permissions to a number of your apps when you use them but it was a lot less of a hassle than doing a factory reset.

    I'm not 100% sure why it worked but it definitely worked for me. I had tried clearing cache + rebooting several times prior with no success. Figured some of you might want to try this approach since it's relatively low risk/low loss. Seems like certain apps could have had erroneous/unnecessary permissions and doing things that were draining battery in the background.

    btw I did NOT turn on aggressive doze and/or auto-close high power use apps as I figured those are "extraordinary" settings that shouldn't be necessary to have my phone last more than a few hours.

    Received another update but wondering what it would be this time...My 3T was ok out of the box except for one or two bugs/glitches before the update...N after the 4.0.2 update things are getting a bit annoyed...Frequently observing some sort of issues with my widgets...I have made some videos of the same but where do I post them...
