CM10.1 Battery life expanding

I have been having issues with cm10.1 "android OS" using too much battery. And i have seemed to squash out the bugs. nearly doubling screen time. (in the sense that by bed time i had about 4 hours screen time and 10% battery left and now can hit 8 hours in a day)
I am going to slowly try different things to see where hte main issues were. but here are the majority of the changes i made.
1. Wifi, this should be off during the day, simple but true. Also i noticed build.prop had wifi scan interval set to 15 instead of the recommended 120
2. Auto rotate screen, i have read this has bugs in some builds (not sure on ours) it should be disabled unless you absolutely need it, you can add a quick tile for quick toggling. (I honestly think this is the biggest cuplrit)
3. Dev options, try to have all unneeded dev options off. I had strict mode enabled, not sure if it made a difference, but its useless cpu cycles.
4. Battery apps, as helpful as they are, uninstall asap, unless you are isolating a problem they eat cpu cycles trying to figure out what is eating your cpu cycles...
5. Notification Light, its not the LED so much as it is the CPU cycles required for the timing of the led light.
6. sign out of or uninstall/freeze (disable) google talk.
7. disable gps (use quick toggle for when really needed)
8. go to system settings -> google (under accounts) -> maps & lattitude -> make sure "report from this device" is unchecked and if you dont move around a lot (aka you work really close to home) turn location reporting to either do not update, or set location...
9. and of course any other common place one, screen brightness etc...
I will slowly implement these back in to see if they cause the drain to come back.
I think its auto rotation honestly, but it could have been a combination of all of them.

I get 8-9 hours on stock 4.1.2

I get 6 hours screen time in 4.2.2 without doing any of that, and I still think that's pretty bad compared to touchwiz. I use all those functions mentioned (except gtalk) all the time, so cm10.1 is nowhere near usable as a daily driver for me.

So battery is not draining on its own anymore.
Now time to find the culprit.
If its autorotation then the cm team can fix it and that's a good thing

I'm not saying cm10.1 is the culprit. I'm trying to figure out what is and so I can help squash it.

I use Deviant's Xone rom. Get 2 days+ of use depending on how I use my phone. Even with heavy use I get a good day out of it, at least for what I need.

Android Wear Battery Drain

Anyone have an Android Wear watch? I just got a Moto 360 and my G3's battery is getting killed by Android Wear:

I've been using the LG G Watch for just over two weeks now and haven't really noticed any battery life changes.
I do have Holy Angel's kernel running with intellidemand and Bluetooth is always enabled on my phone, even when I'm not wearing the G Watch.
But, I don't have NFC always running, if ever, unless I'm using my washer and dryer and feel frisky with NFC use.
Nor do I use Wi-Fi, it's always on mobile, screen brightness at full always and sync always enabled with all my widgets and apps set to update as often as possible.
It could be the Moto 360, but my wife has the G Watch as well with her G3 and her battery life is fine, comparable to before she had the G Watch about three weeks ago.

Someone was having a similar issue on the Reddit forum for Android Wear and a solution was brought up pretty quickly.
Go into settings --> Apps --> Android wear --> press "Clear Data" then try cycling your bluetooth antenna (off and back on) and try again.
I personally have noticed greater battery life from using my 360, bluetooth 4.0 is pretty light on power usage and not using the massive 5.5 inch display for texts and music controls saves me a ton of battery life.

The 360 is being pushed an update that improves bluetooth connection. May help with battery.

I uninstalled Android Wear and Motorola Connect (which is the same as clearing app data) and I no longer see Android Wear using all that battery, but now Android System is keeping my phone awake a lot. After a day, it had a total keep awake time of 2 hours. It didn't use to be that much.

I just read that. No update for me yet, we'll see if it makes a difference.

I also have the same problem on my nexus 5.
I tried deleting the app data abd resetti g the bluetooth but that doesnt seem to do anything either. Im getting very frustrated with this drain

I also had noticed increased battery drain with my g watch and g3. After trying various things it seemed to be related to run keeper or edemodo. For some reason after using the watch with the apps for a run the battery drain his huge. It is android system using all the battery there is wake lock associated with it. Once I uninstall everything is back to normal battery. Installing the apps don't drain battery. It is only after using run keeper. I am wondering if for some reason the watch is keeping the app running somehow.

Deep sleep

I don't think I have yet seen this phone in deep sleep... I even got a deep sleep battery app that turns off the radios and is supposed to put it in deep sleep but I don't think it's actually going to sleep. From what my cpu manager tells me that it's spending a lot of time at 300 mhz, but shouldn't I see deep sleep as one of the cpu frequencies?
I'm used to my android devices sitting around for hours and not losing much battery because of deep sleep, and I am wondering why this phone doesn't seem to actually sleep.

Which app? "Deep Sleep Battery Saver"? Just for fun, what's your percentage in "Settings" ➜ "Battery & Storage" ➜ "View battery usage" ➜ "Phone idle"?
Can't say much about it, because we know nothing about your overall config... but you're right, it should be below 300 MHz for deep sleep.
ofc. it's not allowed to sleep because it has to send data to the AWS servers. ^^

After about 9 hours it's listed 7 hours on phone idle, or 4% of the battery. In that 9 hours about half of my battery has been consumed.
And yes it was deep sleep battery saver, not all that impressed with it really. I have been testing other settings and configuration apps and disabling system apps, re-enable some as well at the first hint of an undesired effect.
Last year I had an android with a bad battery that I could get almost 2 days of sparse use out of but it only a few hours of normal use. So I have expectations that when I'm not using my phone it won't go dead so quickly

That's a massive leak. My device loses 2% charge in ~ 12 hours. Has it always been that much or since you went on a "removing spree"?
If you haven't experimented with an app like this in the past, try using GSam Battery Monitor (or similar) to get an in depth view.
You can install it next time the device is fully charged, so it can monitor things objectively.
Tap on "App Usage" and then from the drop down menu on the top right "View Kernel Wakelocks", maybe you'll find some clues there.
You should be able to narrow it down to see which app(s) / service(s) is / are sucking tha sweet juice. You know I've dealt with similar battery behavior but I "enforced" it on purpose by deleting crucial apps. ^^
edit: Installed "Kernel Adiutor" again and restartet the phone, let's see which CPU frequencies I get during deep sleep.

Battery drain extremely quick

Hello everyone,
I have noticed an absurd drop of the battery level when I'm using my device for usual applications such as Facebook, YouTube, etc...
When it's on 20% approx the battery reaches zero level in less than 10 minutes. This problem started when I have updated my device to the last firmware available (14.6.a.1.236)
I have re flashed the firmware 2 times via flashtool and the results are the same.
It could be an software or a hardware issue?
Thank you for your help :fingers-crossed:

Thank you very much!
My device has 13 months of use.
I use greenify in root mode, but don't have xposed.
I have used a calibration battery app and still have this problem.
May I use xposed in stock ROM without the risk of bricking my device?

Chances are it's a hardware issue and replacing your battery could fix it:
http://forum.xda-developers.com/son...ttery-reporting-phone-dying-suddenly-t3095120
I had the issue where my battery would drop from >70% to 0% suddenly, and replacing my battery has fixed it completely.

Test disabling "Google Services", "Google Play" and "Get More" in accessibility settings. Also test disabling temporarly the Google Account "Search for threaths on the mobile" feature. I was having quite fast battery drain until I did this. It nearly takes twice as long time for each percent to go down. As for your sudden drop check if you got apps that could interfere. Apps that can modify the battery stats.
Btw I had same sudden drop of 5, 10 and even once 30% when screen was off. I thought it was the battery and it was like that for some months until I uninstalled official Facebook app. Now I dont know if the Facebook app was the reason or only reason but after that it has worked flawless for months and continues to.

I tried everything and the results are the same ?.
I think my battery is damaged. Right now my device is plugged to the charger. After 20 minutes of being connected, my device shows only 7%

P6 firmware upgrades?

My P6 is on the "P6-UO6V100R001C00B635" firmware (EMUI2.3, Android 4.4.2) and drains the battery very quick. To add to that, I notice some performance issues, specially using Google Keyboard where the key "pop-up" when you click in a letter is really slow and when typing it gets in the way...
I'm in Portugal and my carrier is Vodafone.
The updater doesn't show any further updates, but in here (XDA) there is some threads regarding b708 and b709.
a) Does your phone act this way too?
b) In case I should update, how would I do that?
c) Could it possibly break something? Or have any problems with my carrier?
Thanks in advance

a) Yes, to some extent with the battery.
If you'd like to compare with my battery (or anyone else's) , we need to have as similar usage as possible. I usually keep the phone on 'Ultra battery' setting (see pic below) overnight & completely unused - if you can do the same, we can compare what percentage of battery has drained in say, 6-8 hours. Also, close all opened apps before setting Ultra battery.
b) In the same boat: also on B635 & would like to update, but see c)...
c) Yes, it could mess things up. Hence why I asked if it can be updated from B635 in the B709 forum thread (post #372 at present).
My phone is rooted, so I may need to do other steps as well before trying to manually update.

How exactly do you use your phone during the day? I usually listen to music, if not check WhatsApp or Messenger. When using the camera the battery goes down quickly too.

It's not my main phone any more.
That's why I suggested overnight when not in use.
