    Dear all,

    I noticed that many if not everyone is facing battery drain issues in the new COS12/CM12s rom. Instead of answering each and every thread posted on the same issue(s), I thought it’d be good to set up a thread compiling all working suggestions.

    What I have in mind is that everyone post whatever they find to work to let others test, and if it works then we can put it up on the main page for everyone’s benefit.

    I have found the following tips to work for me (and some other users here) on my stock-rooted CM12s and hope it works for you. My thanks and credit to those who suggested it.

    1. Go to settings> privacy guard> Google play services (long press it) > disable "keep awake". Disable "auto start". Disable "wake up".

    2. Switch off "ambient display" and "adaptive backlight" under display settings.

    3. Switch off "search for WiFi automatically" under advance WiFi settings.

    4. Switch off "Double tap to wake".

    5. Use opera mini and disable chrome (I haven't tested this myself as I don't like opera).

    6. calibrate the battery [root required]. Learn how to root here [backup! backup! backup!]

    7. Use the version of google play services suggested by @Tekina in this thread

    8. Switch off "OK Google" from any screen. Go to Settings> Language & Input > voice input> Settings icon> "OK Google" Detection> turn off "From Any Screen"

    Note: these tips don’t solve the problem but reduces the battery drain.

    I just flashed the incremental update 2I3 and will keep everyone posted. See here for more details

    Unfortunately, it is what it is...hence why we should find ways to reduce the battery drain for the time being..

    I used the version of Google play services suggested by Mr Al-Amiri from Wednesday to yesterday.

    Unfortunately, it didn't make a difference to my battery life/SOT.

    Presently trying the latest version of Google play services, as of yesterday. I updated it because I wanted to try Inbox! Will keep everyone posted...

    Uhhh, boring. I'm getting over 2 days of battery and 7 hours SOT with KitKat.
    And now it seems that latest Lollipop build have random reboots, this is going from bad to worse. Wake me up when there is a Lollipop ROM that works dencently, or maybe we should wait for Android M...

    I'm fine with all the bugs, I like using the latest stock version of cm available.

    If I was 1100% focused on battery life and content with using old stuff, I would have stuck to Cupcake or gone back to my Ericsson gf788 ;)

    Maybe.. I used to be someone not affected.. But the drain showed up last week. Now it wont even last a full day. I get some 3-4 hours of SOT without heavy usage these days.. I used to get like 5-6 with games. Turns out the problem lies within Lollipop and cant be fixed by Oneplus :(

    You're right about the battery. I did get amazing battery life in Kitkat (look for links in my signature)..But now everything except the battery is spot on

    Exactly. Many people dont realise that its an inherent lollipop problem...to make matters worse, they dont try and do anything to fix it but they open threads to just b*tch about it...

    Mobile standby showing 14% battery drain.

    Any suggestions? Have done the earlier things but I really would wish to get the battery life back

    I tried most of the suggestions mentioned for other ROMs but I would always get Google play services stopped message to many times. This isn't the best help but for me switching to ownROM fixed my battery drain issues. No privacy guard no nothing just flash the recommended gapps plus ROM and 0% battery drain overnight. Don't know if it is the gapps or the ROM but it helps.
