I'm on CM11 M6 and I recently was forced to switch back to the stock OEM 2100 mAh battery from Samsung due to a heat problem with my external battery. I'm just trying to see if what I'm getting is normal battery life or if there is any tweaking I can do to improve battery life?
ROM: CM11 M6
Kernel: KT747 AT&T 4.4 with Asswax CPU governor and BFQ scheduler
Battery: Stock OEM 2100 mAh
You seem to be around normal results from what I've gathered. On stock battery you should be getting around 4hrs of screen on-time. This of course varies on the age of the battery as they run out of juice as they get older.

4.3 touchwiz only gets me 2:45 on screen time, 4 hours is generous.

I've only ever been able to get 4+ hours of screen-on time with a larger 4200 mAh battery from Hyperion. At the most on either AOSP rom's or stock rom I get about 2.5, MAYBE 3 hours depending on kernel setup.

Yeah thats way below norm imo. I can't prove it atm as I haven't used my phone as much today but I've attached a SS of my stats as they stand atm.
I've got approx 2hrs of listening to music on there. Thus the large difference between screen on/awake time. Otherwise after 10+ hrs of discharging it's looking great to me.
I'm thinking of leaving my screen on for a couple hours tomorrow, I'll come back with the results if I do perform the test.

Here you go gents, after 2hrs of screen on time I still have 50% of my battery remaining. Leaving me with approx another 2+hrs in the remaining battery life as the initial 2hrs was gathered in almost 5hrs. This is using the stock Samsung 2100 mAh battery.

How are you achieving these stats? One of the things about Android that really pisses me off is I always feel the need to do my own power management and I can't seem to find a way that sticks.

I don't do much to be completely honest. The only thing I do specific to power management is use Greenify to Hibernate apps that are causing excessive wakelocks.
Other than that, I have Quantum 3.63 ROM with QuantumKernel 3/16 installed running with intelliactive and row.

Just recieved my 2400 MAH extended battery, I have had the device running now for 12 hours straight with all connectivity turned on (including syncing, wifi, data) and in that time I have also done some web browsing. The battery is still at 100%.
I know it is an extended battery but still, by now my standard battery would be at 50% roughly.
My concept is that the standard battery the phone comes with maybe faulty or have some problems?
Any thoughts or ideas?

It heavily depends on the ROM you're using... I've tested several Sense and non Sense ROMs and the variation of the battery could go from 1 to 3 days aprox. I'm actually using OpenDesire latest ROM and its easy to get 2 days of battery life with a normal use and 3G/Sync enabled all the time.
Obviously having a more powerfull battery also helps...

Well i've got an unrooted desire and using stock 2.2 rom. The battery life has been so bad, even when i turn syncing off.
I know its an extended battery but still why was the standard battery so bad
Hmm. Not sure. I don't have a bad battery life, but that sounds pretty awesome as far as battery life goes. You wouldn't happen to have a link to where you bought that from would ya? Would be interested in taking a look at it my self. Is it larger then the normal battery, or just higher capacity? I know many of the aftermarket batteries are a good deal larger then the stock ones.

I can't see how your battery could possibly show 100% after 12hrs usage
It's either bad battery stats, or the battery status indicator isn't scaled correctly for your battery.

it is probably because its voltage figure is still higher than that of a standard one.
I've gotten the 2,100 mAh extended battery. I've turned off lte. and with NO web surfing or video, I run out of juice in 6 -7 hours. Not even a lot of calls. Maybe 20 minutes max. In Settings, the battery tab shows Android OS using 60% of the battery. My wife's Droid X show Android OS at 2%
What's going on? What could be using so much of the battery?
Any references to where tishas been discussed?

how many days have you been using the extended battery? i also had 6-8 hours when i first got it, but just wait a couple of days, you will be fine. it takes a couple days for the battery to actually settle. i have had the extended battery for over a month and now i get 12-14 hours on one charge, with LTE & WiFi & GPS on, 40% brightness, and quite a lot of use
Just got mine yesterday... also having similar results the first full day of use...took off the charger at 10 and was at 25% by 6. I was at work only slightly browsing forums, web, calls, etc ...

Me too got my gnex and full charged at 8am and usually i will be down to 25% by noon.
I have tried flashing kernel (fransco) and rom (bigxie) and same.
They are talking about the device is not getting deep sleep. Any recommendations on what apps could have wait up or prevent the phone from getting deep sleep? I assume email push, IMs? But then iphone has them too and they can last long...
Any help is appreciated. Thx.
when you get a new battery, the first few days are gonna suck.
I'm sitting at 14.5 hours @ 29% left. I leave 4g on all the time. I'm a moderate user, heavy user sometimes.
Yes Android OS is the culprit. The problem went away after I put a the Open Kang Project rom on it.
I didn't hear about an official 2100 mAh battery. Maybe it's not original. Not original batteries are most of the time over stated. you can remove 50% of the mAh in that case.
I bought the official 2000 mAh battery with a new back cover (because the old one won't fit) and it gave me 10-20% more autonomy. Now it's up to 12h
2100 is the battery for the Verizon Nexus, 2000 is for the GSM one

Use CPU Spy to track how often your phone is going into deep sleep and Better Batty Stats to find out what is wakelock'ing you phone.

This is nonsense. AOKP probably does provide better battery life but that has nothing to do with "Android OS" being "the culprit". Battery life for Android OS is reported differently in ICS than in any previous version of Android, that's why it shows a higher % than previously. It's neither a bad nor a good thing.
Hello,
I have received new galaxy nexus with stock JB but the battery life is really poor.
currently its showing:
57% Discharging
8hr 16m 18s on battery
Screen - 61%
Sygic - 9%
Phone idle - 7%
Map- 5%
Cell Standby - 4%
My screen brightness is made Auto.
I am using 2G network.
Plan to use the stock flavor for some more weeks.
Please help on the battery life and also how to underclock this stock JB (if possible)
If you want to under clock all you need is to unlock and root. You can stay on the stock ROM. Also... the battery life really doesn't seem to look that bad to me

uh... 61% of screen on time is the percentage that the screen used of the portion of the battery that was used. it will always be the highest if you use the screen.
what is the time of screen on time? not the percentage.

If you could clock 4h+ after using it down to 5% battery, then there is nothing wrong. But you could under volt for a little more juice.
Beamed from my Grouper.
normally, i get around 3h30 screen on, 1d and a few hours on one charge.
with JRO03R, hit almost 4h yesterday. rom+kernel built with gcc 4.7 could have something to do with it as well. no uc/uv, io sched sio, governor interactive.
my guess is that your network coverage isnt so good.

This might not be relevant, but I was using the stock JRO03R image + Linaro kernel and I magically had little drain overnight, while with other custom ROMs my battery was losing capacity like crazy. Granted, there isn't much running to drain it, but seems impressive.
Also, with that ROM I managed to get pretty decent (6400 in Antutu, but just 2200 in Quadrant) benchmark results, which is weird since it's stock-ish.

yeah, it might not be relevant, i think bad/jumpy network coverage is more to blame than anything else; but, even for me, that have great network coverage everywhere i go (inside the subway i get normal coverage!), my build of JRO03R so far has been performing great. tweaked a few here and there, built with gcc 4.7, lost like 2% over 9h (sleep, wifi/sync on) on the first cycle! very happy.
I'm at 22 hours on battery with that JRO03R + Linaro ROM and I've got 2h 30 screen time, benchmarked using Antutu, Quadrant and Vellamo, kept everything besides Bluetooth on and had brightness set to Auto/25 percent. Seems decent, but not impressive since mobile data is not used, but rather Wi-Fi.
i have the extended battery of 3800 mah. but im still having bad battery life. ive tried all the basic things to fix this problem. (sync off, location off, 4g off, etc) i even put on airplane mode but i can only reach up to about 2 hours on screen time. my bro has a note 3 with a 3100mah battery. why can he last the whole day and i cant even last 5 hours on battery? i even tried using titanium backup to remove google now launcher and google search as this also eats up battery. what else options can i use. (i used wakelock detector and app permissions to stop wakes) thanks.

Thanks for the speedy reply! Currently I'm at resurrection remix 5.1.1 (latest) using fancy kernel r50. CPU over clocked at 1.3 (not a big difference) and govoner is ondomandplus. Scheduler is sioplus. And read ahead buffer size 1024. That photo is the amount of time my battery dropped a percent.... Sometimes I catch it slippin. And it drop 2 percent. Then when I lock my screen for about 30minutes it goes up 2%. And yes. I wiped battery stats. But still to no avail. GPU clocked at 512 BTW. I have the multi core power saving on too. Set to 2. I use greenify to sleep apps also. Any ideas?

The thing with extended batteries is very often their actual capacities are far less than what they quoted. I suggest you try getting hold of the official extended battery (I can't remember the actual mAh maybe 2100) as with it my phone could last from 2.5 - 3 hours of on screen time, depending on the ROM and kernel.

Was using CM11 M releases until the theme engine bug introduced in the recent M6 build. So I have been trying out different ROMs and SlimKat has been the most stable. The SlimKat stock kernel is good enough otherwise Fancy Kernel is a stable and better choice.
Here are screenshots of a day of quite heavy usage while connected to the WiFi with the latest stable SlimKat Build 5 with its own kernel, using the Galaxy Nexus official extended battery that is 2000mAh. 2 hours 45 mins with 30% left to go.
By the way I rebooted the phone twice to change the LCD density as shown in the graph.
I manage to get 3 hr sot and 1 day uptime with vanir and its stock kernel. Maybe the gpu @512 mhz and the "power hungry" io scheduler are killing it. Try some tweaking. A diffrent governor and tunables. Try Nephilims settings.

Vanir has always been so bad with battery life for me. Stock battery and extended. Dies in 1 hour for stock battery. And dies in about 2-3 hours with extended. Very little sot. About 20 min

Wow I don't think it's very legit. It could be just above 2000mAh in real life and then couldn't hold as much charge after a while that's why the battery drained so fast. Not to mention the risks of using dodgy batteries [emoji46]
I think I bought mine from a Korean eBay seller for at least $30 or more. The battery is also NFC-enabled and comes with a back that added a bit of thickness so most gel cases could fit.

One other thing to note is that even with genuine batteries they will start to lose charge or can't hold charge like it used to after 2-3 years. That's why I think phones with removable batteries are better especially if you plan to use them for up to 5 years. You can just get a new battery after 2-3 years

As mentioned, battery life is completely up to your usage. Some steps to try though which can be used across any rom is to give Rom Cleaner a shot and to use Greenify. This will rid any rom of bloat that could be sucking up battery and better allow the device to enter deep sleep where the real battery savings are had.
A well optimized kernel would give you some savings as well. I can personally say that on ARHD 5.5 with Elemental kernel .15 I'm seeing about 70% battery left at the end of a normal day. For me though that may only be one 20 minute call and an hour of screen on time. Even when flashing and messing with tons of settings for hours, the phone has never reached a critical battery level for me. I
It's more about the way you optimize (or debloat) your phone , than the ROM you are running. Use battery monitors like GSam or Battery Drain Analyzer and freeze apps that are causing you huge drain. Greenify is also good. Ideally on the M8 you can expect around 6 hours of screen time if you're optimized correctly.

This. I am able to get about 6 hours on stock, ARHD and Insertcoin. With power saver on, that ends up around 7-8 hours of screen time. Coming from a Nexus 5 that got 4 hours typically, I'm pretty satisfied. I'm inclined to believe ARHD will get "slightly" better battery life than CM since it is based off the stock ROM on the M8.
Generally the OEM skinned roms have better battery life and benchmark scores opposed to aosp. Happens all the time on Sammy phones and HTC apparently too. Posts above mine cover most you'll need to know. Its all about optimization and frankly that part is extremely fun and especially rewarding IMO. Gives me an idea for something like a community made thread on different battery tweaks/voltages :good:
