Hi guys
I am on Cognition 1.5.1 with Speedmod T40 and experiencing high Android OS usage which is chewing up my battery. The phone was pretty much on idle/light use and I do not have many applications installed - just basic ones like Facebook, Watchdog, betterbatterystats, battery monitor widget, imgur, Skype, Talkbox, Viber, Whatsapp.
I have also just calibrated the battery by charging full, calibrated with app and now discharging
Anyone able to help? Something is definitely going on and im unsure what it is. Please let me know if you require more screenshots

Same here.. getting a 3% drop during a 2 hour sleep...and a 5% percent drop during a 30 min web browsing.... cant identify the source of the drain...using bbs... android os is the culprit.. i guess..... everything was fine with cognition till recently... help
AOS Bug has been a problem since Day 1 of SGS2 release.
Thought the android os bug had been sorted in 2.3.4
Definitely AOS - I dropped from 100% to 88% within 2 hours with minimal light usage to no idle.
Also I have turned off my WiFi policy to off when the screen is off, but it's still turned on in Battery Usage stats ?
Whats the solution here ? Try VR 2.5 with Ninphe 2.1.3 or speedmod ?
No problems with the battery consumption on KH3, the GPS kicks ass too.
Specs after 29hrs of usage:
How many minutes have Android OS been running per hour on your phone? Having 3-4 minutes of AOS CPU activity per hour is very normal and not a bug per se.
This will of course cause high percentage of total consumption in battery stats if you don't do anything else, but it will take many days before AOS itself drains the battery with 3-4 minutes of CPU per hour.

I can't speak for the OP, but I'm having the same issue and my Android OS CPU activity is over 15 minutes an hour.
Mine drops atleast 10% an hour no matter what i do. Tried two batteries, roms and kernels. Settings, alsorts and still tge same results. Im not to clued up on the battery stats thing but i have apps using battery that aont running or even been ran and my os usage is also very high. It been in the mid 50s a few times.

Same issue for me
Using Cognition 1.51 out of the box and battery is subject to continual drain. My Os usage history is 4 hours, over 1 day 10 hours ..much to high. I'm thinking about trying a wipe and reset and flash again to see what's up.
a full wipe and reflash rom i suppose.. and removed bloatwares
I'm still running on stock firmware and was affected dramatically by this bug. After upgrading to latest KI4 via KIES, this got even worse.
So I tried something. I disabled WLAN permanently (and only activate it if it is really needed) and removed my microSD card.
THAT did the trick! Don't know which one or if both help such a lot.
I had some mp3s for ring/sms tones on that card (in /media/notification) and Android silently moved apps to that SD (not the internal flash).
That means that Android somehow always needed to access the card (->Android OS), for playing tones (sms) or ringtones. Or even for loading icons in the menu from the SD.
When I removed the microSD card my battery lifetime instantly went up from 12-18h (Event / Suspend / Android OS Bug) to 3 days!
it's a kernel-bug
with the SiyahKernel v1.8 this bug should be fixed ... works for me ... 4% Android OS at the moment

I was thinking of rooting my phone and installing bionix fusion after getting sick of dealing with the battery problems. However, I am concerned about two main things and I haven't seen the exact same thing asked, maybe because they are obvious though =
I read about passwords being stored in cleartext if it's rooted from androidcentral a while ago. I only really use gmail for e-mail, is this a nonissue for me then?
Does the fusion rom overclock the processor by default? I'd rather leave the processor at default speed.
you can dl fusion without overclock. or with overclock and just install set cpu and scale down to 1ghz
Great battery life is not just a matter of the rom you are using. You can be running the most battery friendly rom on the planet but if you are a heavy user, have twitter, facebook, email updates running all the time, and/or heaven forbid playing Angry Birds for hours at a time, you can kill the battery in a few hours.
This screenshot was taken tonight when I got down to 15% battery life. I use gmail, touchdown, handscent, and make phone calls.

Just out of curiosity hour foist you get your dislpay count so low
Times never wasted when your getting waisted
for me, I'm loosing my battery from...doing nothing! It's annoying the crap out of me. I've been obsessively closing apps with the task manager and services as well with mixed results. Most of the time I'm still loosing 4-5% per hour when the phone is idling. So, yes, switching should help me.
Anyone know about the security issue from the first post?
A factory reset might help just as much as another rom. You might also have a bad battery. If your phone is actually doing nothing, then its doing something that you dont know about. I was certainly doing much better than 5% per hour while it was idle.

Thanks! exactly what I wanted to know.
It depends on what is draining your battery. Lately my battery life is hit and miss. Sometimes I am getting 40hrs a charge and sometimes I am getting 25hrs a charge.
For me most of my battery is getting drained on Cell Standby. The past 2 days i have been getting 3-4% battery drain on standby.
I have Fusion 1.1. GREAT rom, but there is something happening to my cell radio. Fusion has JI2 modem installed. I tried flashing the JI6 and battery life varied from 2-3 of 3-4% battery drain. I just flashed back the JI2 modem end of last week. And i have been getting 2-3, 3-4 or 4-5% drain. Right now pinning it down is pretty frustrating. But I will find out the best combo for my phone eventually.
Mine only can last for about 1 day and 12 hour with MINIMAL USAGE
Is it normal? Or there is something wrong with my battery?

I have a problem too, my battery life is about one or two hours, no 3G, no Wi-Fi.
I don't know what to do, I calibrated the battery in CWM. I use MiniCM7Prov21 too.
i have the same problem...today at noon it was 100%... now at 5pm it's 50% and i did nothing...not even a message...
...when I don't use the phone....it lasts me about 2 days....when I do use it, to check e-mails, facebook and whatsapp. it lasts me for about a day....
but does battery life depend on how much Free RAM there is available?
Well now I guess its okay now after doing some battery calibration
My battery now can last almost 3 days

Well this is my method of calibrating.... I don't know if this work on other phone but - Don't blame me if your battery faulty.
1. Charge the phone to 100%(while on)
2. Reboot into recovery
3. Delete battery stat -advanced>wipe battery stats
4. Off the phone
5. Charge it for 35 min. (I heard charging when its already 100% can harm the battery, so u can skip this if you like too)
6. Reboot then see(Rebooting use few %, so it may not be 100%)
7. Use the phone till it completely 0%
8. You can repeat this 2-3 times If you want
I also use the app Memory Booster to kill all the apps that might be draining battery secretly in the background .(Only kill user app)
The max usage vs. time was 13 hours with:
1. About 1,5 h to 2 h of music on headphones.
2: About 40 min to 1 hour of wifi
3: Few minutes of call and a few messages.
4. About 1 hour with screen on (without counting the above usages) using calculator.
5:One Reboot.
Rest of time the phone was in my pocket or in my desk, laying. In 13 hour, reached 15%

About the upgrade, try using CWM Installer, it is somewhere, just use the search and you will find it. Upgrade the CWM, and then try to upgrade the ROM.

Download GSam battery monitor from the Play Store to determine what is causing the battery drain.

The battery drain during usage is within the normal, but in standby it is too high, which I do not understand!

Using the battery app see what app or service is keeping your phone awake. That would be my guess as to what the problem is. I would also suggest flashing cpalmers kernel as well, which has been really good for me in limiting awake time.

Install BatteryGuru, give it a couple days to learn how you use your phone, and watch how it saves your battery once the learning period is done. I swear by this app, it brought me from almost a day to about a day and a half as far as battery life is concerned.
I installed the Gsam battery, it shows that "phone radio" was sucking down a vast majority of the battery.

Then you must be in an area where service isn't good and your phone is searching for service which kills the battery quickly. To conserve battery turn on air plan mode and then turn service on when you get into a zone with better coverage. This will help your battery a lot.

My opinion..don't install any more apps than what you only use. You install more apps it will obviously suck more battery. What you do. Root/unlocked the bootloader and install a sense 5 4.1.2 base Rom. I came from stock and since I've installed a sense 5 stock Rom I've notice a big battery saver comparing from the original sense 4+ stock.hopefully that helps.
Thanks all
Strangely none of this helped the battery drain is too high in standby, after resting (no apps installed only stoke apps) and even flashing sense 5 rom still 15% per hour and even in Air plan mode . The strange thing during the use of the phone the drain is normal.
I haven't yet seen any type of discussion regarding the battery life after the 5.0 update so I thought I'd bring it up and see what others are getting.
As for myself, I manually flashed the image from Google and did a factory reset on all data. So far I am not impressed with the battery life. I could not be any happier with the fluidity, performance, etc, of the tablet after this update, but SOT has gotten immediately worse.
When new, this tab could easily rip off 6-7 hours SOT with my typical usage, almost all with Cyanogenmod. More recently it has been 5-6 hours, but then again it's two yeas old.
My most recent experiences as far as SOT: last night my tablet was at around 50% battery with only 1:47:00 SOT. That was with mixed usage: browsing, light gaming, and so on.
Just this morning I only did some web browsing and after 15 minutes of SOT the battery was at 90%. Typically on 4.4.4 (CM 11), I could expect 96% battery after 15 mins of web browsing.
Again, I'm still getting used to the battery performance with the update, and currently plan to drain the battery down to nothing and let it fully recharge. I was just curious as to how your battery experience has been with the 5.0 update.
I think my battery life has improved. Mainly browsing and watching Netflix. 30% left and well over 6h SOT.

Damn, well I either need to work on improving it or my battery is just losing it.
Mine has nearly doubled, I kid you not.
Out the box I never got more than 5.5 hrs out the nexus 10, tried a few custom ROMs with the same result. I'm now at 6 hrs SOT of video, browsing and using an art program and still have 40%. That's near enough ten hours. Well happy.
I haven't used mine yet in a comparable way to before the update, but so far it also "seems" like battery life has improved.

Well, like I'd planned, I ran it down to 0% last night. It actually got to 14% when it jumped to zero and died on me. I let it charge over night and the battery life has immediately improved. I'm guessing during the update the battery stats got a little messed up.
You should try installing "Deep sleep battery saver" from the appstore.. i use my n10 about 3-4 hours a night and charge it once a week.. DSBS is just amazing.. overnight i use like 1% or less while its off..
my battery life has improved by a huge amount, this was one of my major complaints of kitkat!
Battery life is worse than before for me, dont have actual numbers but it is definitly noticable...
Overall experience is so much better, great job
I did ota sideload...
Hoping for new OTA to fix that and other bugs like random audio loss (fixed by reboot) and that priority star notification that keeps turning on
No random reboots for now, on KK i had few a month but i blame Chrome for that.
I ended up having 8h 45min of SOT (4% left of battery). I did clean install from factory images.
After running it down to zero last night (remember it jumped from 14% to zero and died), I unplugged it this morning and browsed news and played a few turn-based game for 30 mins of SOT. When I put it down it was at 95%. If you do the math that is a projected 10 hours SOT. Now, realistically speaking, I don't expect it to keep that pace and hit ten hours, but it's much better than the 92% w/ 20 mins SOT that I was getting before the drain and recharge. We'll see how it goes from here.
Running stock unrooted. Android 7....what's everyone getting for battery life. Mine sucks. Getting around 3 hours screen on time. Android OS is using as much as the screen is.

Same thing here after updating. Android OS is currently at the top with 10% followed by Android System with 9% in my phone at the moment. System is draining more than the screen. Weird.
Same here. On DP5 battery life was better for me.
same for me, system and Android on top, weird.
What's the reported "Keep Awake" time for those processes? Right now, for me, is Screen on top with 10%, Android System and Android OS next with 8% each. However, the keep awake time is only 3m41s and 11s respectively. That doesn't look too bad, actually.
The OS requires almost a week to settle. Calm your tits.

I installed it last night and so far today I'm at 3% per hour after 9hr25min elapsed. This only has an hour of screen time but that includes about 20 HDR photos (which in MM would have KILLED my battery), BT and WiFi are both on continuously but not connected, GPS is on high accuracy, screen timeout at 1 min, several reboots cycles (trying to figure out how to wipe the cache), etc. In other words, I'm on track for a 30+ hour day, and I'm not doing one thing to try to conserve the battery. Granted there's not much SoT so far but still, I'm impressed. Even more so because tribal knowledge seems to think that the OS needs a few days to "settle down" before true battery life can be assessed. I'm not sure I really buy into that but if it is true, the battery endurance should be stunning...
Have been getting the same results in the Beta and now with final release having the same problem./ Battery life is no good. And doze doesn't seem to kick in even at night. Android os and Android System taking as much mah as the screen. Not good.

Here's what mine's doing so far. Note that it seems to Doze more or less the instant the screen shuts off.
Same issue here, battery life isn't super impressive.
These don't have much meaning without context: How are you using them? How much SoT? Are all the radios on? Etc...
Did factory reset. See if it helps. I'll post after it, "settles in"
Doze seems to kick in, but I don't know whether made it more or less aggressive than before (I'm guessing less), where battery gains are now, and how they're spread out. On MM, I was getting the typical 2-3% drop every night. For the past three nights with N, the drop is 5-6%.
Received the device a few hours ago and updated to N.
All default settings, no additional app.
No 3G/lte as I don't have yet a nano sim.
Bt is on but not connected.
Positioning is on battery saving.
Screen brightness is at 33%.
After 40mn of web surfing with wifi, or playing with the menus I lost 6%.
I'm happy with that :good:

Quick question how did you update so quickly if you just got it?
My second cycle but this time with Ninja Kernel and some kernel tweaks. With sync and location enabled the whole time. Lots of web browsing, video streaming, plus a few minutes of gaming and phone calls. It's not spectacular but not too terrible for me either.
Mine isn't bad. Updated from DP5 using OTA in TWRP.
Unencrypted, rooted, with EX kernel and some CPU profile.
