I am having piss poor battery life. I went to sleep with 93% battery life, and when I woke up about 8 hours later it was all the way down to 43%. Something isn't right. Any tweaks I can make. My friend rooted my phone, and I am quite the newbie with this stuff, so please try and be as specific as you can. Appreciate it.
It isn't the ROM. You either have a rogue app running or a bad battery. Most of the time its a rogue app. To verify you can check your battery use and see what's taking the most, or wipe the ROM clean. Not install anything, and see how it fares.

Well, I am pretty sure it isn't a bad battery because on stock GB my battery life was fantastic. Something is definitely wrong.
Under battery use I see:
Wi-Fi 29%
Display 22%
Cell standby 22%
Phone idle 20%
Android OS 5%
Android System 2%
Anyone?
I was having battery issues on virtuous as well even with the recommended radio and a completely bone stock install, with the cpu set to max at 1ghz. I did this: http://forum.xda-developers.com/showpost.php?p=16251182&postcount=154 last night and battery seems much much better today.

Last straw was last night. Had 13% battery life left before softball last night and knowing I wouldn't use my phone during the games, but having been burned by my battery before, I shut my phone down before the games. Played softball for two hours then turned my phone on. Booted up long enough to see that I had 0% battery before it shut down again.
What am I doing that's causing this? I get maybe 10 hours out of a Seido 1750mAh battery. I have no apps that do background updates. I keep my display on "dim" most of the day. I go most days without even making or receiving a single phone call!
Ideas? Thanks for any help. This is really frustrating.
Cyanogen Mod 7.0.3
Kernel: 2.6.37.4-cyanogenmod+ [email protected] #27
Baseband: 2.05.00.06.11
Seido 1750 mAh battery
I'm not sure, but there have been claims that Seidio inflates their numbers and their 1750 mah battery isn't actually that much. Has this been something that has been happening gradually? Like your battery life is degrading over time and now it's at an unbearable point?
Try a different Kernel or Baseband. I'm using MIUI w/ incredikernel and get great battery life w/ stock battery. I'm also using 2.15.00.07.28 Baseband. I use SetCPU to set a screen off profile of 245min 245max, havn't noticed any lag while having that set. If you wish to update your radio easily you could download "Inc Bits" from the market. Great app has all of our phone radios, all you need to do is rename it and move to SDcard.
Agree with tcberg2010 here. Try incredikernal with Smartass governor. Check out vipermod. I was having intense battery issues which i posted about a week back. My suggestion would be to get spare parts app and check partial wakelock to see if anything is keeping your phone up. I use maps occasionally and it turns out that it was causing partial wakelock constantly. After disabling a locations and gps i am back to standard battery life. Looking forward to next cyanogenmod update, hope there is a fix...
If your phone died while it was turned off, then I would either have battery tested or get another one it could have an internal problem.
Yeah unless the phone some how got turned on in your pocket (I'm not sure how, but it has happened to me), There should be minute if not no drain on the bat at all. I'm not sure where you can get it tested, but I would certainly be wary about that bat. Do you still have the stock 1300? I'd check to see if it looses charge while the phone is off. Maybe there's a short in the phone.
Thanks for all the suggestions. I'm at about 10.5 hours right now and 7% left with the only thing I've changed being the battery. I went back to my stock battery. Going to try a new radio first, then vipermod.
try the "battery moniter widget" from the market. it keeps perfect tabs on your battery, can tell you the REAL mA of your battery, temp, usage stats, all kinds of stuff. it's really a good app to use to watch your battery...you could also use MIUI, and watch your battery life almost double. it's superior to CM7 in so many ways. and the people that have used both, i think pretty much agree...
I'm not sure if I'm doing somthing wrong but I installed srf 1.2 with genocide kernel 2.0 and the battery life is just crap. I inplugged my phone and it was asleep for 5 hrs and it had 12 percent battery drain. When im actually using it, it dies fast. I've undervolted to -75uv on 1ghz have it set to conservative. At 100mhz its at -200, 400 -100. 600 -75, 800 -75. Am I doing something wrong?
You should ask this on the actual srf thread in development.
Two things you can do:
1. Battery Wipe. Search the forums on how to do this.
2. Give it a few days to recalibrate your battery to the new rom. My first 3-4 days on the SRF 1.2 and Genocide 2.0 were pretty pathetic. I got 6-8 hours of lite use. After the first few days of complete battery cycling (full charge to dead battery), I can get a full 16 or so hours of constant use. It's nothing great, but a lot better than stock.
If your phone doesn't sort itself out within a week of use, reflash the rom according to the instructions, doing a complete wipe of everything 3 times. The rom works great, you just have to give it time.
You can get an app called CPU Spy to verify that it is going into Deep Sleep and also Spare Parts and check the Partial Wake Lock to verify no rogue apps are running.
12% drain after 5 hours in deep sleep? Man...that doesn't sound bad to me at all. That's slightly over 2% an hour.
Agree with the guys about calibrating the battery though. Just remember, it will take a while for the battery to 're-learn' how to properly operate, so it will probably suck for the first few days or so.
I've read you should wipe battery stats each time flashing a kernel, but I don't believe I ever have.

That user cannot post in the development forum with having just 1 post. So they are in the proper location for their question.
Oh thanks, I didn't know that. Also is not charging to 100% normal? It maxes out at 98%.

I believe QBKing77 has a video on how to wipe the battery stats and calibrate; very helpful for those who haven't yet done it for themselves. (big shout out and thanks to QBK77 for the vids!)

Yes that is completely normal. It does this so the phone doesn't overcharge the battery, which would only harm it in the long run. (Or so I've read on here.)

This is about what I see as well. I always check screen off battery drain by charging to full before I crash for the night. Of course I calibrate first and give the battery 2 days to get conditioned to the new setup. CPU Spy is a great app to monitor how your phone is using the battery like stated above.

Make sure all your apps have syncing turned off unless you start the app. You will find that a lot of things end up on at first for no reason.

This. Especially facebook which seems to turn sync back on. Also pulse reader was a big one for me before I caught it. Besides that gmail should also be set to manual refresh only. Just use spare parts and look under network usage. These are the big ones. Also there are several apps for battery calibration. One more tip, remove those useless widgets! You don't really need them and they drain drain drain. with this set up I get a day and a few hours out of genocide and srf.
cd's or tapes?
Hi,
like the titel said, i experience huge batterydrain on CM7.2 RC2/133.
I am using the stock CM7 kernel that comes with the rom. I reflashed it several times but not much changed!
At first my device didn't go into deep sleep, but since the last reflash it does.
Over night i loose ~10% ... flightmode is activated.
After 1,5 day's the battery is empty... even if i dont use the phone. Wifi/3G/bluetooth etc. are allways OFF.
I also untervolted the device but nothing changed.
I am charging my battery at the moment, so i can't post any betterbatterystats log's. But i will in some hours!!
Basically my question is, which kernel do you use? What kernel can i use on CM7.2? Are there any better ROM's when it comes to batterylife/performace?
PS: i never flashed baseband or wifi modules etc. when i installed CM7.2... just did as it said in the "how to install CM7.2".
Try this.
1. Empty your battery.
2. Charge your battery for 6 - 8 hours.
3. After that remove battery stats.
I tried this as I'm having battery drain on NXT ROM. Before that my battery can only stand for one day then need to recharge. After doing this, my battery still have 50% after a day of usage.
Just saying, it has been confirmed that removing the battery stats does absolutely nothing.
so should i try another kernel? Which fits for CM7.2 best?

You really should upgrade to CM9 unless there is a reason you're holding back.
My battery discharges pretty quickly and I just don't know what to do anymore...
It usually goes down pretty fast when I'm connected to wifi. I think the main culprit might be Kernel (Android OS). Please take a look at some screenshots I took while using the Gsam battery monitor app and Better Battery Stats app and correct me if I'm wrong.
I have stock ROM, stock Kernel and my Radio version is: 5.1204.167.31
What do you think I should do? Change the Kernel, Radio or maybe both?
And if so, what would version would you suggest for my stock ROM?
Or should I just replace the battery and hope that fixes the issue...
Wifi will definately drain it quicker, usually keep mine turned off until I use it. Depending on how old the phone is definately affects battery life, mine is now just over 2 years old and I find that although it charges to 100%, it will drop to 91% in the first 5 minutes of using it. HTC has a self test in the dialer enter *#*#3424#*#* then follow through to the battery test. I think phone needs to be in airplane mode and has to be fully charged, then leave it on for an extra hour or two. Test takes an hour and from memory if battery is above 70% it passes.

Mine does the same. It drops to 91% fairly quickly after charging. I did the HTC battery test about a month ago and it showed 81% battery left after the test (it said that if it's below 70% the battery might be faulty).
Since I made this thread, I managed to change the stock kernel and now I'm using Alex's kernel. The battery usage is much better but still the Android OS or kernel drains much of the battery.
Do you think changing the battery completely I might have better results?

Before Alex's kernel, I tried XM's latest kernel because I read on OP's thread that it works with stock ROM too, but I never managed to boot my phone after flashing it. (and I did everything right I think: cleared fastboot cache, fastboot flashed the boot.img then flashed the zip in recovery)
I am all for trying lyapota's kernel but the download links have been removed in the official thread I think. Can you provide me with a link for downloading please?
Try app called greenify

Thank you but I am already using Greenify.
Only one option left, to try and remove some bloatware stock apps and see if that changes anything.
I've looked all around for any thread similar to this - couldn't find it.
Long story short. I rooted my phone and installed CM11 (Sept 14). My battery used to last around 30 hours. Now I'm lucky to get 8 or 9. Without any use, I lose around 40% during the night (7 or 8 hours). I used to lose 7 or 8%.
Is anyone having the same issue?
Go to the battery tab in settings and find out what is using the most energy. You can also use greenify to monitor usage.
Or try diff kernel..
what are your governor settings, and clock settings?
You can use Better Battery Stats to track down what is causing the drain.

Clock is stock, governor settings are at "interactive". I got Better Batery Stats. "Android OS" is draining my system. There were a couple of modules mentioned. I was expecting a rogue app was eating up all processor cycles.
I downloaded the Deep Sleep widget. My phone had a 35% deep sleep time.
I'm pretty sure it's doing something all the time that is draining the battery...
So I installed DS Battery Saver Pro. All I can say is WOW. Battery drain went from 7% (on stock Galaxy Note 3) to 40% on CM11 to...
0% overnight / 97% Deep Sleep
That's right. 0%!!! I can't believe it! Battery life is so much better and performance is basically the same.
I guess something was keeping the phone awake with CM11, and DS Battery Saver Pro fixed it!

Okay, it seems like the app Greenify helps a bit but doesn't completely solve the problem. Try that and let me know what you think.

Not that this will help you, but I had the same issue. Normal usage would drain before the day was over...went to Tweaked 3.55 and problem went away, which sucks because I LOVE CM11 minus the camera...for some reason I think the camera is always better with stock based roms.
DS Battery Saver Pro only did so much. With normal usage my phone simply won't last a whole day. CM11 is killing it. I have nothing else installed...
Found it!
So, I found what was eating up the battery. The battery stats didn't help. DS only saved some of the battery at night. The phone was simply consuming obscene amounts of energy while on and every indicator seemed normal.
It was ART!
I went back to stock Touchwiz and hated my phone so much I was this close to selling it and getting a OnePlus. But I reinstalled CM11 and decided to add apps one by one to find out what was going on. Everything was fine and yesterday I finally enabled ART in the end. The phone wasn't any faster, but it went from spending 3-4% battery at night to 45%. And during the day, it dropped 1% every 2 of 3 minutes with light use.
So, there it is. Blame ART and never enable it on CM11 if you have battery issues.
