Prior to rooting my phone, I was using cupcake with 5 widgets open, auto sync, power manager, missed call open and my phone would last for at least 11 hours. Now I'm using cyanogenmod 3.6.8.1 and my batter drops to 20% in 5 hours. I'm wondering if there are tips and tricks for root users to improve battery life?

Less stuff you have open the more it will last. I'm not on cyanogen rom so not sure if he overclocks the rom, if so you can underclock it.
There's a thread already about Battery performance - http://forum.xda-developers.com/showthread.php?t=540344
The Cyanogen ROM does automatically overclock but I believe it should scale. If not try the Open Overclocker Widget, click advanced and change the CPU speed for when the screen is off.
If you read Cyanogen's development threads, you'll see that he has been looking into the battery problems. Testing done by some members in those threads makes it look like the battery isn't necessarily dropping that fast, but the calibration / voltage sensor is getting out of whack. I know I've let it run down a few times where it drops rapidly (hours, but quicker than it used to), but then it spends hours in the single digits.
Also, if you believe the tests (seem very thorough) over in the accessory section (in the 2400mah battery review), the Dream power management is very conservative, so you can run your battery flat without getting the voltage dangerously low. Charging every chance you get is a great idea, but you can still use the phone all the way to the shutdown point.
Simple Poll.
Have you seen a decrease or increase?
Someone can explain this battery drain?
in a lot of roms based on 2.2.1 there is a big battery drain, in some other there isn't.

Reboot after unplugging from USB and battery drain is gone. For further improvement install SetCPU and reduce min/max frequency. I am getting more or less the same lifetime as with donut ROMs.

OK I have done.. but the problem is that when I use it 3 o 4 minutes (for example I install an application using a file explorer, then I read a message and then I come back to home) m battery get 5% lower...
In standby I lose 10% in 6 - 7 hours (I think this is normal).

I am currently without a computer therefore immune to this USB bug. I flashed CM6.1 to this and the other g1 and both suffered substaintial amounts of battery drain so I nandroid restored back to CSDIv4 and still the lowest frequencies and settings did little to combat the descending digits. So I tried this...
Recalibrated my battery
Flashed SuperWipe.zip
Reboot
Flashed SparksMod's latest
Reboot
Wiped battery stats
Unplugged...reboot
Battery lasted 23 hours the first day never seen anything like it.
Lifes great.

I'm using TMUS-G1-Froyo CM6 remix..
and I'm using the new radio with +14mb.
The rom flies but the battery go down too fast.
I'm using setCPU with 256 - 528 mhz while screen is on, 122 - 256 mhz while screen off.
If I go to battery use in settings I see
Cell standby 45%
display 28%
phone idle 22%
android system 3%
I don't think is normal... cell standby is the battery use by cell radio..
I wonder if the new radio give a big battery drain..

I got real excited when I heard about the new radio and hboot even thought that its exclusion was the source of the the battery issues. Haven't been able to try it as I'm without a up-to-date PC at the moment.
It would be real nice if I could find a seasoned dev who understands battery consumption. I thought the kernal was the main culprit but I've tried two different roms with the same kernal and one has notably better battery life than the other. So confusing.

I can't use my phone with this battery drain...
I will come back to official android OTA-AOSP 1.6.. with +14mb.
So I'll test if this kernel with 14mb is a cause of battery drain.
PS: I'm not a lover of rom customizations.. I think the official roms are the best.
The other are all too heavy. I'm not a fan of cm kernel, that is too heavy for g1.
I would see an official OTA 2.2 without customizations, so every one could customize as he want, and if he want.
PS: OK I flashed AOSP 1.6 using ezBiff_kernel to have 15mb (cause I have new radio and spl, so I can flash roms only using this kernel).
Result: my battery life is similar to froyo 2.2 roms... so the problem is:
1) Kernel? (ezBiff_kernel is based on cyanomod kernel... ... ... heavy as death)
2) New radio/spl?
3) My battery (I don't think so.. it's new battery. I buy it 2 weeks ago and in the beginning it works so well.. but then I flashed new radio/spl and new kernel for 15mb..)

Come now.. the cm pershoot kernels are super optimized so they don't collapse under the heavy as death rom that is usually on top of it..
I get mixed results with that kernel between testing and feedback.
A test phone can idle on wifi+2g for days on the stock g1 battery even after a usb unplug.. but on more common use with syncing services its not performing as well as I'd like..
Some of it is fixed with less swap/compcache or changing clock speeds 122/480 for most the speed but lower voltage levels. Also the interactive governor may work better.. I'm testing these ideas if results are good my next kernels defaults will use them.
Cm/pershoot have some interesting new power management code from other htc devices.. So hopefully soon all will be better. (I merged most of it to my kernel but there are some loose ends.. works well untill the phone locks up.. so no public release yet)

Ok sorry I talk without knowledge. I really don't know the effect of the cm kernel. I only know that all roms based on cm release, with cm kernel, are so heavy and slow.
I like your rom (2.2.1 AOSP) and I love your new way to get 14mb.
But I have this orrible problem. My phone has a lot of battery drain when I use it. With screen off, no problems.
I have never used swap or compcache in this days, and I also try different clock speeds (not over 528mhz).
The result is that when I unlock my phone, I go to settings, I see for example 95% battery. Ok, I return to home, I open a message, I return to home, I open contacts and I scroll some contacts without make calls.
Then I come back to battery settings and I see that is 92-93%..
in 2 minutes of soft use.. I think this is impossible. If I open stupids 2D games... ahah in 5-10 minutes my battery lose 10 - 20%.
I remember 1 year ago, with 1.6 (no cyanomod) my battery was good.
Now it isn't (I have a new battery).
Today I flashed aosp 1.6 with your kernel for 14mb (I have new radio&spl) but nothing... I lose a lot of battery percent as in froyo.
So I think problem is or battery calibration, or something to wipe, or cm kernel, or new radio&spl + your new kernel...
Now I'm recalibrating battery (is at 1% from 2 hours, I'm not using it.. ) then I will recharge for 8 - 9 hours and then wipe battery state, but I have done this process a lot of time without a benefit.
I'll try to remove the new radio+spl (so also using standard kernel) if my battery continue to lose percents so fast.
I'll keep you update on my "story".
PS: Sorry for my bad english!! XD
OK.. after a day of low discharging and a night of 8 hour of recharging, I wiped battery states, I wiped data-cache-ext ecc... I flashed aosp 1.6 and ezbiff kernel..
"battery drain" continue...
I will try tomorrow to reflash death-spl and old radio..
BTW, is normal for hours battery 4v at 90%?
On the back of the battery sais 3.7v... I thought 3.7 was the voltage for 100%
Update
I know this thread is a little old, but I ran into this problem as well. What I found was that the official US radio (2.22.23.02) used considerably more battery than the international one (2.22.19.26i). The other thing I noticed is that switching to "use 2G networks only" in mobile networks settings and disabling data over mobile drastically improved battery life.
I also noticed that wifi used a fair bit of juice so my recommendation is to disable wifi if you're going to be on the go for a bit, and disable data/3g if you're just going to be hanging out in the local webcafe, your/a friend's house, or some other location with wifi access for a while.
If you wanted to be ambitious and cared enough you could write a script to use as a shortcut on the home screen to do the swap automatically (detect which setting(s) are enabled and swap them to the opposite).
With those changes, you should get much better battery life. My thoughts on different Froyo flavors is that possibly different builds have different settings by default. Cyanogen comes with data and 3g enabled by default so this will quickly suck out your battery if you're running your 3g, 2g and wifi antennas all at once.
The stock build (1.6) got about the same battery life as I'm getting now with those settings applied. With either build, having all antennas on all the time will drain your battery very rapidly. Being a little more cognizant of the settings (perhaps you also had it set to 2g only on the stock build) you're using will significantly improve your battery life. And when I say significantly, I mean night and day (but the antenna version definitely does also make a difference... at least in my case).
Hello all
i´ve got my 4x Hd since one month now, everything is okay but the battery live is terrible. In some reviews i read that the phone should get 6 hours of screen on time and a lot of users here say that they reach 2 days with this phone but the maximum i reached with my phone was 20 hours with 2 hours screen on time. And no, i dont play ANY games on my 4x and the screen is nearly on minimum brightness. I have tried EVERY Rom in this forum (rom folder contains 80gig, lol) but it is very hard to manage for me that the battery lasts a day. Better Battery stats says that Baseband wakelock and wifi wakelock drains the battery at most (even on v10h and v20a,I thought that these wakelocks are custom Rom related...?). Also ive tried a lot of battery saving tweaks like greenify for facebook, trickster mod to reduce voltages and underclock to 1ghz, but nothing helps much. I ordered a second battery too (polarcell) and it gives a light improvement, but coming over an day ist quite impossible...
I would be gratefull if someone can suggest me a good setup (Rom + Kernel + Apps) or some tipps to save battery...
Sorry for my "bad" english....:0

According to what he has written, he seems to have searched and practiced a lot.
Please just ignore the question if you do not want to answer.
It is nearly impossible to filter good knowledge from a thread which has been started months ago so sometimes it is good to make a new start and share the most useful.
6 hours is overkill of onscreen time. 2 hours is what you should get with heavy use, 3 hours with moderate, 4h and up with video watching.
install custom rom and kernel, keep wifi and data off while phone is idle and you'll get miniscule discharge while the phone is not in use. if you need to sync messages or mails, use dsbattery saver, and let it turn on wifi/data once per hour for 2 minutes and force sync.
keeping data and wifi off will conserve a lot of battery.
baseband_xmm is weird wakelock. try werewolf kernel, as it seems he completely fixed it from overeating the battery. as for wifi lock, it seems that it's rom-related, and that stock has best stats with wifi on, but a bypass of that issue, is ofc, to use wifi only when you need it.
as for underclocking & changing governors, i didnt find that they increased battery life much (for me). only advice is to experiment, and from personal experience see what's the best you can pull off. (f.e., carbon 4.2.2 i could pump 4+ hours of onscreen time with medium use, but i've tested other (better) roms, with more functions, that i simply dont want to go back to it )

If that is true then the OP should have been able to formulate his own opinion as to which ROM and Kernel works best for him. The simple fact is that if he's only had the phone a month and has tried every ROM then he has only run each one for about one day - that is not enough time to form any kind of opinion on how a ROM actually performs. By far the best thing is to choose 3 or 4 ROMs that have the features you want and try each one for a week, take copies of the Bettery Battery stats and review after doing those tests.

If everybody could understand this fact, there would be less questions on the forum.
No custom ROM or kernel can create miracles when the power consumption of the screen is the unchanging variable in the equation and you have to turn the screen on to use the phone.

yeah, that's not normal. even with gaming it should last more than 30 minutes. my best advice is to dig deeper into the issue, see what's really wasting the battery. not many tips i can give, since my worst drainers were wakelocks, not apps using abnormal amount of battery while phone is active
My galaxy gear has Null 22.1 installed, stock launcher running, no full ui. Cpu and governor options are set to the default. Min is at 200 max at 600. My gear has not been worn, but it does receive bluetooth notifications for calls, sms and gmail. In 4 hours it will have been 3 full days and my battery is currently at 35%. I assume the battery life would be worse if I was wearing it all day.
What tips does everyone have to squeeze the most life out of this?
- Is the default cpu and governor options the best to use?
- Is 200 min/600 max the best combination for cpu?
- In battery manager 66% says phone idle, 12% screen, 11% android system, 2% bluetooth, is that the optimum thing to see?
- I have brightness set at level 3, is 3 the optimum?
- Are there apps that should be removed that could add extra battery life?
One of the biggest battery killers of all is the wake on motion function.
I was thinking of flashing null v19!so that would use the stcck kernel 800mhz instead of the duel core I think this affects battery life a lot but I can't find null 19 anyone knows where I can get it.

Yup if you dont use that function with null 22.1 it will sip battery.
I turned that function off yesterday before work as a test and im still at 100% 18 hours later. I dont have bluetooth tether on either right now.Testing what the battery is like with that on today.
The current version is null 22.1 not 19. I assume the dual core is off by default or else it would crush the battery. Can anyone confirm that?
No duel core is always on its in the new triangulam kernel I find stock 800mhz has much better batterylife but null 19 was the last firmware with stock kernel that's why I am trying to source it.
Wow then you are right we all need that. We should be able to flash a kernel in TWRP instead of having to downgrade to Null 22.1. At least you can on any other device in clockwork or TWRP
I don't see the reasoning behind going to 19 for this kernel.... everyone agrees that 22.1 is much better on battery life than 19 was...
you could use the kernel from 19 on 22.1 I guess... but I would think that the ROM is set up to use the new kernel better now so that might not be a good idea either.
If I have the wrist motion off i never go below 90% battery in a day at work now (with it on i stay above 80%), does it really need to be any better than that?
The only thing we were looking for was a way to turn that second core off to test battery life.
I tested time and time again I am back on stock now and battery life is much better the watch was never designed for duel core use even though it can use it.What lets it down is the battery too small if we could get some undervolting going things could be different starve the CPU bare min to save battery life.

care to share what your settings/apps loaded are?
i've reflashed without gapps,turned off motion, but with BT connected (non tethered) i can't last more than 5 hours. Is your BT always connected
i do have FBQuickview app enabled so i get FB updates but even without that i was not lasting too long
QUOTE=carajean;50530689]Im going on 24 hours on battery half that is bluetooth tether. Right now im sitting at 69%[/QUOTE]
My best is 15 hours but that is with bluetooth on all the time, with GPS bluetooth going, and tablet talk and google voice being used regularly. I would like a little better life but that is good enough to make it on an average dsy at work.
Although my battery life is nothing to brag about, when others are getting multiple days of use, in the spirit of the original post for tips:
Disable Watch Styler and use a standard clock theme. Apparently, custom watch faces eat up the battery quicker than a stock theme.
Hi,
first, thanks to Maclaw & co for their s3 ports!
I've flashed CM11 on a new phone, and am very happy with it. The only straight up bug I found: reading contacts & SMS from the SIM card was impossible. Reverted to stock backup, pulled them down and backed up, then went back and imported them in CM11.
On battery drain - this is my first smartphone, and I ditched stock immediately. So I am missing some frame of reference here. Also I just got this two days ago, so I will need another week for some real-world statistics. But from what I've seen so far, I kind of doubt it will make it through a single day. Now I don't expect it to hold charge for a week like the old Nokia I am migrating from, but still...
What kind of battery life can I reasonably suspect? I understand "it depends", but let's say location turned off, mobile data only when needed (maybe an hour/day or so), dark themes, dim screen, etc.. Basically I am trying to figure out if this is an issue with the mod/build, or just how things are in android land.
Now I do have some suspicions that cpu load is a bit excessive. During "idle" (no apps running but htop, location&mobile data off, wifi on), both cores are at ~30% consistently. Attached is a screenshot after 1) bootup, 2) turn off screen 3) turn back on after 30min and start htop in terminal. The base system also seems to draw more power than the screen (set near minimum brightness). But again, maybe normal?
I went with CM11 because it looked like it was the most widely used / best supported one, but if it actually has some battery issues I would need to try out some alternatives. Would be happy to help in debugging if there is something I can do as well.
Have a look at Slimkat. Been using this for quite some time and I have no complaints about battery life. Obviously the battery life will depend on how and what you use your phone for.
Pacperformance is a system app in Slim so you can set your governed, CPU Max/main etc. Use wake lock detector too just so you can see if pacperform is showing your not getting deep sleep.
I have used many, many custom roms and CM11 has never really appealed.
Good luck in your quest!

Thanks for the tips, I'll check them out. I was a bit wary with trying out other mods since I'd like to not spend too much time on it and just have it stable, but I think I will just give them a go - easy enough to revert from a backup. Regarding governors, I checked and mine is set to interavtice, there are a bunch of others available though:
Code:
$cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
abyssplug pegasusq hotplug conservative ondemand userspace powersave interactive performance
Hmm, most of them I've never heard off - any preferences?
BTW, for whatever reason battery drains a lot slower now (maybe it just needed a few cycles to settle in?). I also verified via adb shell that it idles at around zero load when the screen is off.
