I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?
I'm running the CM7 w/the 2.5 radio - I'm in a 100% full time 4G area, but seem to have worse battery life when the 4G radio is on, so I just keep the phone on 3G - if I need the faster data I can always turn it on and off.
I'm running the stock kernal, no overclocking or setcpu type stuff going on.
Would like to hear from folks running this ROM w/killer battery life, what are your settings, tweaks, etc. Please specify if you're running an MR1 or Mr2/2.5 version and/or running the latest OTA 2 radio that just came out like yesterday.
I just turned off my FB sync (I forgot about that). I don't have gmail set up to sync automatically either.
I'm going to do this procedure a little later today and see if it helps, this is for the EVO, but, ya know....
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally.
Anybody else try this?
today will be my first full day of work use w/this ROM so we'll see what happens.
Best to keep 4g off if not using it. Also, turn Bluetooth off when not in use.

i had horrible battery life the first day - then it got better. then i flashed mr2 official and battery life is really solid. getting like 15-20 hrs with 4g always on, bluetooth on sometimes. one important thing is having a custom lighting table which i will post later.

I have never, nor do I intend to ever do this. I got an extended battery for a reason. I can go all day and then some on the official roms, and all of the Sense roms.
I am not new to CM7, I have run it on both an Eris, and an Incredible. Both devices got FAR better battery life on CM7.
I am not complaining about this rom, or Slayhers hard work. I simply want to gather information so that we may help him trouble shoot.

This is exactly what I did lol, I had lost 10% in the first 90 minutes, now I am at 58% at 5 hours. I have been streaming google music for 2 hours of that 5 though. I would guess I should have seen an increase in battery usage, but have not.
The battery readings are wrong, I get a full day on 4G with my stock battery and see those numbers for cell standby etc. I use lean kernel though
Sent from my ThunderBolt using XDA Premium App
do you see those numbers for BLUE TOOTH though? We know good and well some numbers are fake, but that does not mean all.
FYI I am now at 37% and 7 hours and 7 minutes... I have not used google music since the last post and I am seeing the exact same battery drain as when I was using it.
I have absolutely horrible battery life when I'm at work (which is basically a bunker). On a normal day, my battery will be dead within 6 hours just sitting there on my desk.
However, when I am at home (great 4G signal), I see my device getting upwards of 16 hours with moderate use.
I will also say that since I upgraded to the most recent radio, I have been having much better battery life at home. Additionally, my phone has stayed much cooler with the most recent RC + new radio combination.
I heard if you change the render fx to n1 calibrated, then you will get like 1 hour extra of battery life. You can change the render fx by going to cyanogenmod settings.
11h32m11s on extended battery 69% left
The other numbers have to be wrong. Theres no way cell standby is the number one battery user.
my cell standby is also showing 30% with the new OTA 2 radio.
I switched to dream kernel (have not wiped battery stats) and am now at 88% after two hours, that puts me at 6% per hour verses yesterdays 10.

only works for AMOLED screens.
edit: to be clear, it only saves battery on AMOLED.
so what i have found is that after installing dream kernel and messing with the governor settings... along with being connected to wifi. my battery life has improved tremendously. i wiped battery stats this morning after a full charge and didnt notice any change.. then i flashed the kernel and messed with gov. settings... after rebooting ive noticed a huge huge difference.. just my 2 cents for anyone who had battery issues like me
Yesterday I was able to choke out 20 hours while in a 4G area the entire time.
Running RC 1.2, Imoseyon's leanKernel extreme mode (extremely undervolted and OCd to 1.4GHz) and using the InteractiveX governor.
Also, I just happened to reboot and surprisingly it only took away 1% of my battery. Amazing considering whenever I did that on a Sense ROM, I'd experience a battery loss ranging from 7%-10%.

What settings did you land on as best?
cpu is set max to 368 mhz(very low) but i can crank it up if im doing somethign like playing games or downloading and want speed. brightness is at about 15-20 percent. the dream kernel and mr2.0 radio have made a big diff too. the dream kernel made the biggest. usually when id power off or reboot id lose 6-10 percent same as someone else i saw post. now i lose maybe 1 percent which is a huuuuge difference considering you lose 10 percent just because you reboot. also i try to stay on wifi wherever i go. on 3g i def notice it drain quicker, but i am no expert and there are a lot of people on here who by far outexperience and outknowledge me(my new 2 words) so im sure other people have some suggestions

That is strange I am also using CM7 with an extended battery and still have 41% left after 14:56 on battery.
battery use does show
cell standby 31%
phone idle 19%
android system 19%
wifi 11%
dialer 10%
display 6%
voice calls 3%
I have an unlocked T-Mobile Sensation 4G and I've tried a lot of different rom (with Sense and AOSP, GB and ICS).
I had made battery calibration every rom change (Full charge -> wipe battery stats -> do some full discharge/charge circles in normal use).
Every time I have 50-100 mA battery drain in "sleep" according to Current Widget and another battery widget (tried another to commit that Current Widget tells truth).
The phone settings are maximum power-saving:
Fixed small brightness
2g only
Data and auto-sync are turned off
Wifi only if needed
CPU is downclocked to 1.2 gHz
Battery is stock. Phone is two months old.
In my regular usage (1 hours of calls, 10 min wifi) phone dies in 12 hours after full charge.
It is not my first android and I'm not a total noob. My Desire HD with one year old battery live 2 days with my usage.
Also I notice, that sometimes battery left is not accurate and changed after reboot to a bigger value. For example, 80% left -> reboot -> 82% left.
Any suggestion?
Thanks in advance!
Sorry for my poor English...
My suggestions:
1. Use system tuner or a similar app to check up on which apps are draining the most power (keeping the CPU on, etc).
2. If no culprit can be found, full wipe and reflash your ROM, and refrain from downloading any apps, see if that improves battery drain. If it does, slowly install more apps until the battery drain goes up again, and you'll know whats causing it.
3. If reflashing does not help batter life, you might want to try another ROM or kernel.
4. If none of those help, or even if they do, I highly recommend an ANKER battery, it'll at the very least boost your battery life a few more hours.
5. If the battery life still sucks, then it might be a hardware issue and you might want to get it exchanged or whatnot.
I used to have the same high battery drain problem, but after flashing new ROMS/Kernels and switching to an ANKER Battery, I now get 2 days of light/medium use out of my Sensation.
Currently using Insert Coin 4.5.0 with 1.5GHz overclock+undervolt if you're interested in trying.

Thank you, I will try.
How much does your battery actually drain overnight? Should be around 1% per hour or less if all is well. Disregard currentwidget in deep sleep mode as the Sensation has a very broken meter.

I'll check it this night.
With jumping battery meter I don't know if these values will be correct. But when the battery value reaches 0% the phone shuts down immediately and don't turn on. So 0% it counts well.
i think im also having the same issue . i checked current usage when in sleep mode.its between 50-80

12hrs with the standard battery is actually very good for a sense build, without sense it should go around 15 - if the battery is in good condition. The battery driver for the sensation is very buggy and you won't get accurate results with any measurement app. Don't worry about the standby or inuse readings as they will both be wrong.
If you're battery drains faster than 1% per hour in standby, assuming you are in a good signal area, then use a system info app to see which program isn't sleeping, then uninstall that program.
But it doesn't sound to me like you have a problem.
According to the log file it drains 1-2% in hour (now I'm using aosp build, MIUI). I think, new Anker battery is the only way. Thanks to all!
Maybe in the future we'll get a more accurate battery driver...
Alright so my skyrocket is rooted with the faux kernel and sky ics 7.4 speed rom. My battery lasts me roughly until 6pm everyday when taken off the charger at 6am for school (obviously aren't using it during school) so that to me, is crap battery life for such a large battery capacity especially only using HSPA+ no LTE. cpu set at 1.5ghz uv -75mv, ondemand governer, screen off to 384mhz. Noticed Android System uses nearly as much battery as display, at minimum brightness.
Can anyone help me reduce this or give me any tips for better battery life?
in the pics below, i left my phone idle overnight after a 100% charge before going to bed at around 12am. woke up with the phone at 98%.
under moderate useage it will die 10%/45 minutes.

I bought a external charging kit + spare battery package that samsung sells for around $40. An external charger (equivalent to charging your phone on AC while the power is turned off) is the best charging you can give your battery. The worst type of charging is charging your battery while the phone is on connected to a computer through USB.
Of course, who wants to charge with the phone turned off? That's why you should get this package. I never worry about charging my phone. When I'm running low, I just do a quick battery swap. A seriously annoying issue with this phone becomes a non-issue.
I also make sure I try to do a deep cycle charge. I always let it drain to around 5-15% before I swap batteries.
kind if irrelevant but this might be the first phone I might not root or mess with for a while 2nd day of use.stock everything and i'm running on 1 day and like 6+ hours on battery idk if that's the born or not but i'm not on lte either just thought I would share this lol

I think I read somewhere that faux's kernels don't support Wifi tethering. Is this still true? Do other custom kernels have this problem?
I flashed the Paradox rom on the T989 forums with Faux's Skyrocket kernel and I didn't download System Tuner with this ROM (Just kept it the way it was) and it has zero lag and from 6 am to 2am the next night, I only went down to 32% so battery life is the most amazing I've had ever
I had a similar problem on my old captivate. I found a rogue app that was using a ton of battery. Like 74% of my battery. Bat stats said it was Android OS using it. Delete some of the recent apps you may have installed b4 you noticed the bad battery life. I am on SkyICS 7.4 my battery life is pretty good. The rogue app that I found was a game Pirates from Disney.

12 hours isn't too bad for a Skyrocket.
On my phone, I'm rooted, running SkyIce ROM with Faux Kernel. My usage is as follows:
Display-64%
Android System-6%
Android OS-5%
Cell Standby-2%
I average around 10 hours of heavy (constant) use, and about 16 hours with normal use. I'm quite satisfied with the Skyrockets battery life. I've only had the phone for 10 days, so the battery is still settling in. It's much better than the battery life on the SGS II, which got around 8-11 hours.

Hey Guys,
I remember the first two days I had my HOX, i thought the battery life was amazing but now on the 4th day it seems to be getting worse. I don't know if it has to do with the 1.82 RUU or other stuff i have running so I thought I ask.
With the screen off in sleep mode, i lose about 1% every 45-60 mins. The only things I have running are the default HTC sense weather, battery indicator and gmail widget. I just turned the wifi setting where it would shut down after the phone goes to sleep but that doesn't seem to be helping.
Overall today i used it for a few mins for txt and basically installed two apps and i'm down to 80% already since 7:00am. It did push maybe 5-6 emails to the phone while it was off.
Anyone else seeing this kind of battery life?
George
Is this your first smartphone? That is pretty decent battery life for the type of phone it is. You're getting much better battery life than a lot of people in these forums. This belongs in the battery life thread that is already started though.
My phone lasts from 8am to 4am daily, with ~2 hours of screen usage, 1-2hrs of calling, and wifi always on. By the end of the night, I have a minimum of 25% remaining, and sometimes even 40-45% or so.
The only time it dies quickly is when I'm in an area with no service, then the "cell standby" time shoots through the roof and kills the battery like no tomorrow.
Maybe you should download CPU spy and check to see if it's deep sleeping or not. If not, or if it spends too much time at higher frequencies, check out Better Battery Stats and look for wakelocks/other apps that are taking up too much usage time.
Option two you should probably try anyway, CPUSpy or not.
The battery stats are bogus... my phone was off the charger for 2 hours with the screen off and lost 18% and yet my stats say it was asleep... downloaded better battery stats and I'm finding the culprit today

It mean ur phone even if the screen goes off there's process that make ur phone doesn't put to deep sleep (like app with auto update on e.g twitter or facebook and so on, depend on your app in the phone)
In BBS, you can check what things that make you phone didn't put to asleep. You can find it in Kernel wakeup/partial wakeup/other in BBS.

+1 for this. I got about 9 hours with this on. I'm now at 2 days and counting with it off.
WiFi performance will keep your phone awake. It's good for long downloads and such, usually when screen goes off it'll go into low performance mode and will crawl for downloads. It has a purpose, just remember to turn it off after

I actually figured out that that was the problem causing no sleep. I was having WiFi problems which were fixed by this...but figured it may have an effect on the battery too. I switched it off and turned my phone screen off for 10 minutes...right away 10 minutes of deep sleep showed up.
Getting much better stand-by battery life...unfortunately I'm on my phone a lot (for texts, facebook, twitter, instagram, web browsing) and the screen on battery life still won't go past 3 hours! :/

You can use CPU Spy...
There is a battery thread... But to the OP, that's pretty decent.
for me... 29% on for 14 hours and thirty minutes. Screen on 1:32. 1:47 for voice calls. And I did a lot of music streaming.
WiFi high performance is good when you need it, otherwise turn off because it prevents your phone from deep sleep. Fastboot should also be killed unless you need it. Fastboot is only useful if you turn your phone off and on often. No difference for rebooting. Some apps don't like it.

What are your thoughts and what are you using to save battery.
Personally, I think they're a placebo effect, but I never gone in depth to do any real comparisons so I could be wrong. And the M8 has a good enough battery to where I don't consider needing a battery saver.

I ran Qualcomm's Battery Guru app customized for our CPU on my Rezound and now my M8, but ultimately decided that I would just run in standard powersave mode. My kernel lets me undervolt and overclock, so I get decent battery life coupled with fairly good performance without ruining any other battery software.
I use the built in batterysave in CleanROM combined with ART. Great combination.
I use the built-in Power Saver, along with Greenify.

What ever for? [Imgur link, SFW; shows my battery stats this morning]
If I can get 20 hours to 30%, I can probably get 30 hours on a full charge. But I put my phone on the charger when I go to sleep. If I didn't, I'd be shooting for a 40 hour drain. That's kind of high expectations for a stock battery. Why not just charge it every time you go to bed?
I'm running the latest CleanROM in Dalvik mode, whatever kernel comes with it and zero battery saving apps. I do have the option ticked as you can see at the link where it cuts off your data when the screen is off (like Deep Sleep Battery Saver, and others). But the battery saver itself is off.
