Hey there,
I was using the CM7 nightlies for a while, and the battery life was great. However, it seems like ever since I flashed CM7 Stable my battery life has went down. The part I'm finding odd is that it didn't even last 12 hours today and I barely used the phone (especially in the first 8 hours since I was at work). As well, the battery usage shows Cell Standby and Phone Idle combined using over 85% power, which I've never seen before. I want to say it might be some of my apps, but they're the same ones I've been using. In case it makes a difference, here's my setup:
LauncherPro
Trillian
Clock/Weather widget from Fancy Widget
SetCPU on "conservative" setting
Gmail, Facebook, Messages widgets from LauncherPro
Power Widget
Score Mobile widget
None of my sync settings are really frequent, most are hourly refresh, another is 30 minutes. And since I haven't had this problem before CM7 stable I'm still thinking maybe it's something with the ROM.
What I'd like to know is if I should try to calibrate the battery first. And if that's the case, what is the best method to calibrate the battery so the ROM is reporting it accurately.
Thanks in advance
Anyone have any ideas?
I have been getting the BEST BATTERY LIFE EVER since moving to the latest radio.

Which radio is that?
Always flash at 100%. Then use your phone at least 4 days, as in 2 complete cycles of using until you have to charge it again. Do not change your radio unless you are absolutely confident about the things you are going to do. Chances are you have a custom rom which does not match the radio you are trying to flash, resulting in a expensive ¨presse papier`.

I appreciate the caution, but the current radio I have is the version that Virtuous recommended to update to. Is there a more "Cyanogen-specific" radio?

I got the stock radio and it's working perfectly. 28hours of uptime with ease (and everything on, incl pushmail). No GPS issues, good reception and no static in the background.
when you say use your phone for 4 days (2 completely cycles) until you have to charge it agian... what do you mean exactly? i need to charge mine after like 8 hours...

What I mean is that you should, after you flashed a new rom, drain the battery at least two times and charge it again fully. Or charge at 100%, flash and wipe battery stats after flashing to speed this up a little. Point is, there is no definite daily use. You could (usually not) notice a very small difference in batterydrain after flashing, but be sure it's not because of Bluetooth, Wifi, GPS or some other thing which is accidently turn on. That's why I said to use the phone for 4 days, and 2 complete cycles. I do not use my phone as heavy as you seem to do. Furthermore, I take care not to turn Wifi, Bluetooth or GPS on when I do not need those functions.
Been flashing ROMs for a couple of years and have been among the early adopters when new ROMs come out. Have now tried the Blazer ICS ROM three times and it looks beautiful. First two tries i had odd things here and there, but coupled with horrible battery life, switched back to Blazer's GB 4.1 (which is the best ROM Ive ever used). Decided to try it one more time. Wiped eveything twice, re-downloaded Phantom's latest, and flashed it. Ran well all day yesterday and was excited to try it a full day today. Charged it full, then promptly forgot it when i left for work this morning. Thought it would still be interesting to see what the battery would be like with it on, but never used. No calls, no texts, just on, with the wi-fi on. Gone for 10 hours and it had just 16 percent left. Obviously, had i used it normally today, i would have gotten about 4-5 hours, only. Checked battery stats and the OS was 82 percent. I'm using the ROm's kernel and modem is FC24 (which works wonderfully with GB 4.1).
I've installed just a new browser and Root Explorer, but none of my other apps.
Any huge battery saving tips for this ROM I can try before just going back to 4.1 indefinitely?
Battery sounds about right with wifi fulltime on. As for tips
-Try placebo scripts
-Disable all the animations / backlight
-Use black theme / images as much as possible
-Create a deep sleep profile (disable everything when screen off)
But hey if battery is that important to you, just go back and enjoy GB, I know I would but I love me some current OS. well current by E4GT standards

Thanks - will search for "placebo scripts" (not sure I know about those). I have screen at minimum (and it was off the entire day), so that probably didnt come into play today. Will fire up setCPU and try your suggestion. I 'll try this one more day.
Battery life isn't everything to me, but it can't drain like it did today when i didnt even use it. I love trying the latest, but I've yet to experience ICS without deal-breaker issues. Any ICS Roms out there that dont have big issues? I really want to like ICS ...

I would install the TR & TN Black Rom in the android development ( http://forum.xda-developers.com/showthread.php?t=1828068 ) and see how that does, if you still don't get good battery life then yeah ICS may not be for you. That Rom consistantly gets absolutely great battery life for me. I have tried them all and the black rom has considerably better battery life.
Try M'ICS 1.3 , calk & venum tweaked stock or wicked sensations 1.6. Then flash Sleshepic's the_governors_v1.2.3. All of those ROMs I've gotten at least 14-18hrs of battery.

Sounds like something is running in the background. In settings go to development and allow only one background process also flash agat 4.4 kernel. I keep my cpu at 100 min 1000 max with no lag. I get 13 to 16 hours with 3 hours onscreen time.

I bet its the wifi. Ever since ics, wifi would not let my phone go to deep sleep. Try for a day with just 3g. I'm sure you'll get decent battery life. I'm getting about 3 hours on screentime daily. Set wifi to sleep when screen is off. Though there's a problem of wifi connecting back from deep sleep. I just turn wifi on when in need it

Thanks for all the great suggestions. I made a couple of changes and had significantly better results today. Went to a conference all day and left it in the car. Was on for 10 hours, but never used. Two notable changes in my settings today: turned off 4g, and setCPU of screen to 200 max. Yesterday, i was down to 16 percent after about 10 hours of zero use, and today was at 89 percent after 10 hours of no use. Tomorrow I'll use it for about a half-day of normal use and Thursday will be a full day of normal use.
So, for now, I'll continue with Phantom's ICS.
Just noticed that I'm down to 77 percent, having now used it for about an hour. Looks like i need to continue to tweak this. Any more suggestions are greatly appreciated.
In the meantime, how do you set wi-fi to sleep when not in use (besides manually turning it off and on)?
Hmm I have had nothing but good battery life...

I would try doing another very good wipe and some other ICS roms....My current rom went 1 day 4hrs 46min Sunday, That's with texting, Gtalk Tapatalk, couple phone calls, music player and 1 hr 46 mins of on screen time. Running a themed stock ff18 rom. Oh and cpu sleep from the market.
Might also want to try the full FH13 (clearing data) and see how you do with that.

I'm running "black" too. 81% after 8 hours of no use. But I'm in a bad signal area so it's expected. I think it a pretty good ROM and only getting better.
have you tried to uncheck the pulse notification light. for some reason that was making my phone not go into deep sleep.

Great info, guys. On Day 3, using it about a half day, and it got through the day - about 14 hours. Tomorrow, I'll use it like i normally would. Am hopeful it will get 10 hours. Am reading about how to install Agat's 4.4 kernal. Am hoping that will help, too.
Thanks for everything.
My battery life on 4.3 stock was 8 hours screen time (half brightness I believe)
Rooted and flashed a custom rom and kernel 7hr30min screen time
Flashed different kernels dropped to 6hr max screen time (without factory reset)
After installing Xposed and many many modules the screen time kept dropping to like 5hr to 6hr
Updated to KitKat and rooted 4:30min to 5 HOUR MAX screen time PLUS phone got hot ALOT OF TIMES
***RIGHT NOW*** Flashed a custom ROM HyperDrive with Colonel X latest and Compulsion latest BOTH 3hr30min to 4hr30min MAX screen on (EVEN with Jovy23's kernel settings that got him AMAZING battery life with ConservativeX governor - It still did not fix the issue not even a little - I still like Compulsion which was awesome when I was on jellybean) :'(
Same settings for all the above set ups. Whenever I flash a ROM I ALWAYS clean flash and I DO NOT have Titanium Backup NOR do I use any other restoration app. I tried to clear and format every partition. I formatted SD card. SAME issue. I am frustrated by the battery life; it DOES NOT last me a day when on stock unrooted it was easily 8 hours. Also I do not use auto-brightness cuz the sensor uses more battery, so it was on half-brightness)
Someone please help me. The worst thing about a phone is the battery life. I usually browse Chrome and Facebook and for these simple tasks my battery dies quickly (WTH?!). I can't even think about gaming (and I REALLY want to GAME), but I know the battery life would die so much.
Is my phone defective? I tripped Knox. I already had a warranty replacement in like the first 2 weeks cuz of Knox issues stock. WTH is wrong with my phone. I want to format and clean EVERY SINGLE THING on my phone to get it the 8 hours screen on time I used to get. No matter what I do my battery life right now WILL NOT go above 4hr30min to 5hrs screen on. I used to watch Netflix for quite a while back on my stock Jellybean / rooted Jellybean days, now it dies extremely fast.
What should I do? I was thinking of flashing AOSP so it cleans up whatever Touchwiz and Samsung related is on my phone and then re-flash touchwiz so everything is set up correctly. I tried to use the mega-wipe script for a certain Note 3 model but it stopped at like 10% to 20%, so that route did not go well (I manually wiped everything data, internal, etc, before flashing many ROMs and this problem persisted).
I cannot do anything good on my phone until this issue is fixed. I hate clean-flashing and setting up things (I think titanium backup and stuff screws up your system) all the time. I cannot game, I cannot download good apps, I cannot do anything that is not online based or can be backed up online. Apparently my battery state is stated as "good" on the system.
"... All of this in under one day..." Give it a few cycles over the next few days. It'll change. I've been using HyperDrive with ColonelX with the conservative governor tweaked for performance. Can't really say much about the battery life since I have the 10000mAh battery.

Dude, if it's all under one day. You need to let a ROM and kernel set In. You can't drive a car without wheels. Just give it 2 or 3 days it will begin to get better. That's what I think too but I give it some days to stabilised if you will . Then my battery goes from normal to good to great. It won't right away start getting great battery life. Unless you have a kernel your phone don't like and flash another it does like battery life improvements where almost instant at least in my case. Like now I'm getting Ok battery life. It's not the best. But it holds. I might switch kernels tonight to spice things up.

I meant the right now part is under a few days. Idk why i said all under one day (it was late night). This has beena problem since February at least
Trust me I know you have to let a ROM and Kernel set in but my phone keeps working harder than its supposed to. Screen off battery is good, so wake locks are not the problem. The problem is cpu wise something is messed up that it puts my cpu to drain huge amounta of battery
Even you tried another or different ROM still happens?

The rom and kernels might be the one messing your battery life, since your battery is in good state, but why not try replacing a battery if you have an extra and see the results...

How do you find that out?
There is an app that can report this value. The premise is that certain cpu's have different values which indicate how the cpu will perform. The problem is, the same cpu can over time end up reporting different values which pretty much means it is not really a set hardware value and most likely means nothing.
You can find the large thread about it if you look, but it was pretty much debunked as a really value at the time.
first download the new rom http://forum.xda-developers.com/showthread.php?t=2709867

make sure you have a custom recovery
1 go to setting back up and recovery do a reset from there
2 let the reset be done then restart the phone and go to recovery
from recovery do a full wipe factory restet
3 install the zip from the sd card
4 pick the apps you want with aroma installer and install compulsion kernel

Nice battery life enhancer.
You have to let the rom settle before you can get accurate battery life akin to the rom and kernel. Trust me I know this as a fact. I have been flashing roms like crazy since the days of the Samsung admire and the rom takes days to settle.

You made sure to toggle allows allow scanning off?
Toggle either power-saving or GPS only under location?
Power saving mode if applicable?
Turning of haptic feedback?
The always allow scanning seems to be the number one battery killer for me. I turned that off and noticed immediately better battery life. Almost akin to an extra minute per one percent, which adds up.

Yep, did all that stuff from day 1 back on 4.3. Updating to 4.4 was the most frustrating thing ever. Many people here report great battery life with 4.4, but many like myself had it slashed in half upon upgrading. It ruined an otherwise perfect phone.
I love everything about the tablet, but I am strongly considering returning it because the battery is so bad.
I was watching a movie last night, and I noticed that I had 70% left... and after the 2 hour movie I was down to less than 15%. That can not be the norm. That's horrible.
I'm thinking about rooting it to a custom ROM and/or returning it.
Any ideas or suggestions on this?

That is definitely not normal. I've had mine for almost a year and even on stock ROM I was getting 5 1/2 hours (I play a lot of games) screen time with a day or two of battery life. It would help if you posted a screen shot of you're battery usage after your next full charge so we can better help you.

It's mostly stock rom so it very stable, the main engine is the Xluco custom kernel. This rom is using the latest NJ1 the latest stock rom (which is the best to date stock rom) slim (debloated), so your device would give you the best of both world, battery life, performance and stability. I have done the following in order to add an extra 1 to 1 -1/2 hrs to my device.
1) Installed Glowing battery (set to extreme), no need to play around, it does it job well
2)Go into application running and freeze all un-needed service/apps. If you have question about what you can freeze from your list just ask here. Currently I only have these running:
Glowing battery lifesaver, Device test, Google Services(3), com.sec.android.app.FlashBarService, Google Play Music, Snote and Samsung keyboard.
3) screen brightness set to 30%, only crank up when needed.
Good luck

This fixed my battery issue. Thank you. I guess software does matter
Hey guys,
I didnt use any rom before , that why i need your advice. I live in Turkey, and we still didnt get the update of kitkat.
I wanna update rom, but if there is custom roms good for this, i'd like to install it. But some people say battery performance decreases. My tablet's battery is like %10 = 1 hour. I use it for taking note in collage via squid ( papyrus ) app. Thats why battery is important for me.
I use pen almost all the time, its important too.
If you know good rom, suggest me
I get good battery life with hyperdrive but I have not tried any other rom yet. I use it to watch movies at work and I work 12 hours and on full charge is can watch 12 hours movie with minimal brightness and power saver. I work night shifts so it dark where I am and therefore don't need the brightness up.

what if i dont like the rom, can i get back my old rom ?
If you make sure to make a backup with TWRP (as most tutorials would advise you to), you should be able to go back to your original firmware. Flashing a custom recovery like TWRP will trip the warranty bit ("knox") if that's a concern for you, i.e. Samsung might refuse warranty services. If your warranty has expired anyway that shouldn't be an issue (and otherwise up to you whether you take the risk).
I have made great experiences with the temasek CyanogenMod 12.1 (Lollipop-based) that's maintained by joshndroid. Can't but a number on it, partly because I usually charge before dropping lower than 25%, but I'm pretty sure I get well over 10h usage out of it (my battery app says 27h at currently 87%, but of course that estimate is based on me currently not using the tablet).
For non-TW based I would do temasek or BrokenOS. I average 7 hours SOT.
