Hi,
I am on 4.4 and have horrible battery time. It last less than 12 hours with about 2.x screen-on time. I've turned off wake-lock on almost all battery time. Yet CPU spy says deep sleep is only 13% of time.
Most of the tool requires root on 4.4. Yet I can't root my device.
I am wondering if I should go back to 4.2.
1. What's the battery life comparison b/w 4.2 and 4.4?
2. Under 4.2, without root, are there tools allow me to find out what is eating my battery?
Thanks

Hello guys, since I've tested some version of higher than 4.1 android, I have problems with the battery, I'm currently using the stock version (ICS), but the only ones that work with a good battery life is ICS and JB - 4.1
I'm sure it could not be any app I have installed, because even when I finish installing the ROM, the battery dies in a ludicrous speed!
I did a little test, with the phone idle for 2 minutes will be 1 percent of the battery, or the battery dies in less than 2 hours, making it unusable.
I took some pictures of the screen in the settings of the battery.
Please, HELP ME ! :silly:
Hi guys, I am using stock Rogers Moto X and just upgraded to Kitkat. While enjoying the improved response time on Kitkat, I noticed that the standby time(everything off except radio signal) on this phone consumed more juice than on Jellybean. When running on JB, it used to consume about 5% every 10 hours with wakeup time less than 3% showing on Wakeuplock. However, it now consumes about 5% for every 6-7 hours!!
Therefore, I downloaded Wakeuplock, GSam battery monitor, and Betterbattery stats to collect some info. Although their functionality are very much limited under Kitkat, they still can collect kernel wakelocks info except Wakeuplock. The results were collected after I charged my phone to 86% and turning off everything except radio. Time period was 7 hours and 15 mins. See my results on attachments.
You can see that on Betterbattery stats it shows everything was alright. Deep sleep time was 99.3% and awake time was 0.7%. Deep sleep time was very satisfactory. While on the Wakeuplock, it showed awake time was 26%! Although I think it did not reset the time to 0 after I unplug my charger so it probably not that accurate but should be at least 15% of awake time. It also cannot display anymore details under Kitkat. Last but not least, on GSam battery monitor, the result shows pm8921_eoc was keeping the phone awake for 1 hour and 4 min for the duration of 7 hours and 31 min which makes 14% of awake time alone. I have never seen pm8921_eoc this high on my kernel wakelocks. I did not download any new apps(except these wakelock apps) or change any setting to my apps after the Kitkat update so it shouldn't be my apps that causing it.
So what is pm8921_eoc exactly? And how should I reduce its waking up times?

Thank you so much! Guess it's just Kitkat draining more battery.

Its not that bad compared to 4.4 Anne it always takes a few cycles to see how your battery actual is

You're getting less than 1 percent per hour drain....that's better than most. There's no issue. Be thankful.

Noob question. Does the kernel have anything to do with battery life? Me and my wife both have a note 3. Mine is rooted hers isn't (4.4.2). Her battery life is great but Im not having any luck at all. If I charge my phone over night i wake up the next morning with 92% AND ITS STILL PLUGGED IN lol. Its like it stopped charging in the middle of charging. I would then have to unplug it and plug it back in for it to charge completely. through out the day I will get a full day but around 10 pm I would be at 30% or less with moderate use. Now thats ok but for this phone I should at least be at 50% with moderate use right? My kernel is 3.4.0-257432 Sat Jan 4 and hers is 3.4.0-722276 Sat Mar 15. I've used 4 different roms including DK 2.0 and DKX (Which I Love) and its the same thing. I've just stuck with the battery life. is this normal? Thanks for listening guys.lol

Since your GN3 is rooted, I assume that you are running Jelly Bean 4.3 since no one has rooted 4.4.2.
If so, you might try SafeStrap 3.71 and X-Note version 7. I had battery drain problems running the later AT&T 4.3 versions after the OTAs this year. After phone calls, my battery drain was at least five percent per hour. It used to be less than one percent per hour.
With X-Note v7, overnight I see 0.25 percent drains reported by Android Tuner. During a normal day with 25 minutes of phone calls, email downloading every four houses, some texting, and checking sport scores, I usually have 90 percent available at the end of the work day.
One of the biggest causes of battery drain is the dreaded wakelocks. They keep your phone from going to deep sleep and saving battery life. WakeLock Detector from the PlayStore works fine. I found that diagnostics.client.wakelock and NlpWakeLock. The latter can be stopped by turning off Location services. CPU Spy can show you the Deep Sleep percentage you are getting. At night, my phone reports as high as 98 percent Deep Sleep.

I'm actually running kit kat 4.4.2 and SS 3.72. Can I go back to 4.3? Meaning I'm still on the 4.3 (the phone itself) but I took the Odin update for 4.4.2 with Udroid. I hope I'm being clear. So the question is can I go back to a 4.3 rom from a 4.4 rom since I've already Odin flashed 4.4.2?
Go to this thread in XDA to get from Safestrap KK to JB.

Went back and had the same problem. Found out it was a bad battery. Att is replacing it. Did all this for a bad battery. Thanks again
Hey guys,
I have the latest nightly build of CM11on my Xperia Z. I updated as 4.3 stock was draining my battery within 3-5 hours with limited used normally by Google Play Services. I put up with it for so long I have forgot what the battery was like on it before!
At 15:23 I was at 95% Battery. At 18:02 with light use I was at 74%. It Is now 22:47 and I'm at 26% with using some games, internet browsing and downloading a few apps over 3G as well as texting a bit. Is this normal battery life for CM11? If it is are there any other ROMS which have a good battery life but also offer as much if not more features?
On Battery stats the screen is using 35% of my battery, Android system 11, Android OS 6, Google Play services 6. I installed at 18:00 Battery Reborn and it says I'm losing 1% every 4 minutes.
I tried using the conservative Governor but it seemed too choppy and don't know where to set the minimum clock to cirucmvent that, so I'm using interactive at the moment.
all help appreciated!
Hi,
I recently updated to Android 5.0, but now I have an extreme battery drain. While it should be in deep sleep (cannot see, because its not rooted yet), the battery will hold for a bit more than 1 day. On Kitkat it was nearly a week with same apps installed and usage.
Is it possible to downgrade from 5.0 back to 4.4.?
Or has anyone an idea concerning the battery drain?
Battery statistics show "Android OS" as battery drainer.
Thanks,
Butch
It has been said countless time allready, you CAN'T downgrade.
You can try this http://forum.xda-developers.com/memo-pad-7/help/memopad-7-me572-recovery-lollipop-t3288702 but you would to get the files needed for ME176CX yourself.
