Why is my battery life so bad?

I'm running my tmo G2 on cm7 clocked at 1.2, wtih a off screen profile. I don't have many apps syncing, but the ones that are are syncing at least every 2 hours. My cell standby is taking a huge chunk. How can I prevent that? My battery life seems to be terrible, and my percentages can drop enourmously in only a matter of twenty mintues. What causes cell standby? Any ideas?

Hey,
Cell standby is the time that your phone spends on screen off while being connected to the cell network. Try flashing a newer/updated radio and see if that helps improve your power management by the wireless cell signal.

How do I know what radio to flash and how do I do it? Thanks for your reponse.

Theres a pretty useful (although not necessarily perfectly complete) list of radios.
To install, follow the guide there. Basically just download the file, rename it to 'PC10IMG.zip', put on the root of your SD card and boot into the bootloader (NOT CWM Recovery). and it will recognize the .zip and accept the update and let it install. Be sure to note before you do this what radio you're currently on and make sure there is a download available so you can go back to it if need be.
Before you do this, its best to look at all other options to see what could be draining battery such as wonky apps, or unused radio connections, or wakelock issues.
Fwiw, I'm on CM7 too and my 'Cell Standby' is generally in the 30%-40% range in my battery stats, but I get very respectable battery life. You should look into other causes of your battery life as well before just jumping into new radios.

You need to set more profiles with setcpu. Low battery is a good one but, yeah u need the newest radio. Also need taskiller. Auto kill while phone is off. My battery life is supreme

Don't recommend task killers. They're worse for battery and performance, especially in 2.3 (GB has good RAM management), than not running them. They spam kill necessary tasks and don't let background processes properly run out.
If you want to weed out the rogue processes, download Watchdog Lite and see which processes are using the most CPU and RAM and try getting rid of the bad ones.

You must be kidding. I use Taskiller, and its golden. My phone is fast, no lag, and everything works speedy when i need it. It autokills what i want when phone sleeps, has kill button widget to kill things constantly tryin to run. You freaking crazy.

I had my phone running all day at 1.2ghz and used it heavily from 7am-3pm at work and because of setcpu profiles and my taskiller, i never dipped below 40% range. You need to check yo facts about this ish.

You need to settle down. Your claims of battery life with "heavy usage" are susceptible to an unquantifiable number of variables other than task killer usage.
There is no reason to use a task killer with 2.3, I don't think you'll find anyone familiar with how 2.3 operates that thinks a task killer is better. I haven't seen a person promoting task killers heavily since 2.1.
I think that everyone has their own way of setting up their phone, and whatever works for you works for you, but I don't think that a task killer is the way to fix OP's issue. Identifying problem apps etc is.

How can you argue that the processes that run in the background shouldn't be killed. They are a constant drain on power levels.

I think El Goog can argue better: http://android-developers.blogspot.com/2010/04/multitasking-android-way.html
Sure Task killers give you the sense that you are controlling the variables, but what's to say that those apps don't start again without you knowing? Android was built with this in mind and rather than allowing the processes to keep running, they are placed in a low level state of hibernation until required. They are ultimately killed off automatically when Android calls for it. It's really down to personal preference and there really isn't a need to get so defensive about it. It's just the way it was designed.
@OP: Give us a list of the apps that you have installed since observing your battery limitations. Perhaps there is an app in there that you use that is set up slightly incorrect or is a known resource hog.

i agree taskillers should be used.. but i do also agree some apps run inthe background or stay running when you exit them or don't fully exit. this is why i use fast reboot. basically kills all the apps.. with cm7 i actually have fast beboot for long press on my search button.. since i never really use my search button.. works like a charm. when im done playin a game, interet or facebook mostly i'll use it to kill everything.. works great. and also if you don't use 3g\4g then you'll notice battery life is amazing.. i have an extended battery chichi one, and dont use 3g.. i get off work, texting all day and have beluga up and open all day.. about an half hour of browsin internet. 30\60 minute of calling.. and i usaually am around 60 at the end of the day on the worst... just my 2cents.

Task killers may seem like they do their job, but these newer versions of android have a built in task killer. Just Google it and get your answer. This is a good discussion though. I mean what else is sugghested? I don't believe I have stuff runnikg in the background. What are some your guys profiles? Or tips?

I've got the usual. I mean I use plume and that syncs every 2 hours. I have lookout running in the background without GPS on. So I don't think that it could be. Beautiful Widgets syncs every 3 hours for weather. The battery is just consumed by the cell standby. I want to decrease that.

Thanks for supporting my theory with the link. Exactly what I needed. I do agree he needs to not be so defensive about it lol.
Task killers use up RAM and CPU to sit there and spam kill apps that keep restarting. They will keep restarting because they are trying to finish tasks they're assigned to do. If you just let them finish running, they will complete the process, and sit in RAM, no longer using CPU. At idle, my background processes are using 1% of my CPU and I have 75% of my RAM available. There is no need to run a task killer to stop processes. I used to be an avid task killer user, until I realized that it is causing more harm than good.

So what kinda numbers are you talking about here? How much battery is cell standby taking up? and how are your battery life numbers with a normal day's use?
The only thing I could generally recommend without knowing more is dropping your clock down to 1ghz. I use these profiles:
Battery <100% 1017 max / 245 min ondemand
Battery <10% 768 max /245 min conservative
Battery <5% 368 max / 245 min powersave
Screen Off 368 max / 245 min ondemand (I sometimes have wakeup issues if I set to 245max or use the powersave scaling)
Temp > 42*C 768 max /245 min (necessary for any OC I think, good to stop your phone if its getting towards overheating)
Also, using a standard screen brightness lower than 100%, or just autobrightness can help. The best way to cut down on cell usage is an app like Juice Defender, which turns off your 3G data when the screen is off (and enables every 15min (or less/more) for updating). This is really useful if you don't turn your phone on/off every 1min like I do for text messages (turning data on/off often causes more drain than just leaving it on). Unfortunately, Juice Defender isn't updated to work on 2.3 yet .

Honestly, it's trial and error. Try underclocking back to 800MHz if you have OCed and see if that helps at all. If it is in fact just cell standby that is sucking your power dry, then backup your phone with NANDroid and get the latest radio. Flashing radios are less complicated than ROMs since it is easy to flash an older one over a newer one if you change your mind.
I believe a list of radios was posted earlier but I will try to track down a larger list for you.
Good luck!

Partially true.
Nandroid backups don't backup your radio, only your ROM. Flashing your radio is completely independent.
But yes, it is easy to flash back and forth between radios. Just be careful that you flash proper radios and have an escape plan to go back to your previous one (aka have your old one in a flashable form also) in case the new one doesn't work.
Here's a list of radios for the G2 I recently used: RADIOS. But as I said before, I think there can be other issues other than radios at play here.

RAM will use the same amount of power regardless if it is 100% full or 5% full. Task killers are useless, linux can manage its own memory just fine.

Exactly. The link previously posted explains it pretty well, but here is another good one:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
Keeping processes in memory is not going to kill your battery life. But I would think that using up CPU cycles to kill the process unnecessarily, only to have it respawn (more CPU cycles) would actually consume more battery then if you left it alone.
I haven't seen any convincing argument that 3rd party task killers should be used (and solid arguments against them). They are mostly just a vehicle for the developers to take your money.

Battery life is horrible, yet not much is running?

I have my cpu settings on 245 245 powersave when the screen is off, yet I'm still getting horrible battery. I use my phone extremely lightly, maybe once in a while to listen to music. Check my emails, chat every so often. I use to get 48 hours with light usage. Seems I cant figure what is causing my battery to drain. I have a craigslist app, I had one search enabled so I deleted that to see how much it will effect. Does google talk drain that much? In the past it was fine. My usage shows the 2 main ones are cell standby and phone idle. Any tips on finding out what exactly is draining my battery? Im running CM 7.0.2??, latest stable, forgot. Koni's was the same. I thought maybe sense drained the battery, but it doesnt seem to be the problem.

Click the link in my sig and run that battery conditioning routine for one. What kernel are you using?
And dump SetCPU. Useless app, seriously...

1. Update to the latest stable version...7.0.3.1 released this morning.
2. Google talk could be draining, but I've never used it
3. Perhaps install it under a clean install and see if that helps.

Get tge system panel app. It'll show you what apps and everything that's eating your battery. Does the kernal your on perflock unlocked for over /under clocking cause if it isn't setcpu doesn't work.

+1 SetCPU is great for Sense ROMs, but not necessary for CM based ROMs.

looks to me like you were in pretty crappy coverage. that makes the phone work hard. it's justifiable that you'll have a lot of battery drain then, even while sleeping.
you can greatly reduce this by:
1: upgrade to newest cm7
2: flash a custom kernel. may i reccomend tiamat 4.0.1?
3: put your governer on smartass, and uninstall setcpu. smartass does it better.
4: use a bsm from viperboy. they decrease voltages. work almost too well.
5: USE JUICEDEFENDER! this will save a ton of battery in low coverage, because it turns off 3g when screen is off. this still lets you get calls and texts, but with mobile data off, your battery will last much longer while sleeping.

what prl are you on?

Battery usage monitor?

Hi Guys!
I am facing a very extreme battery draining situation...
Something is keep waking up my phone while my screen is turned off.
Is there any good app out there I could monitor / Find out what is constantly waking up my phone? I can not find any good app for that.
Thanks for your help in advance.

Settings->About Phone->Battery->Battery Use
Get yourself rooted and grab SetCPU. I have a profile set on that which underclocks my CPU when the screen is off. Doing this GREATLY increased my battery life.
I also use Tom Hubalek's Battery Gauge Widget to help me monitor my battery. But, after using the RCMix S v2.0 ROM and calibrating my battery (and the mentioned CetCPU settings) I get a good day out of my phone with a lot of wifi and 3g usage.

Never had any issue so far with my battery... I am checking battery usage in the settings menu but it is not enough. Need to see what exactly using my battery 'cause its unacceptable to drain 60% in 5 hours... The only thing I can see that something is using (waking up) the phone even when the screen is turned off...
I am using SetCPU as well with Smartass governor... can not be the problem...

Also set a profile for screen off - i have it set to 245min-245max smartass. It seems to save battery more than just set on the main screen.

Have you tried changing the Wi-Fi sleep policy? Also, pocket mode and fastboot, if you have those options.
My SetCPU is set to OnDemand. I thought Smartass was unstable and gobbled more power than it should? I dunno, though, I use whatever the ROM developer uses for the ROM; I don't change anything.
But you're right, my phone has lost 61% in 14 hours. 60 in 5 is wrong.
I think JuiceDefender has some of the features you're looking for, though:

Ach, I have mine to 245-600MHz when the screen is off. Any less and my rom is lacky when the screen wakes. Had the same settings as you for other none Sense 3.0 ROM's though. MAJOR power saving. If you leave your phone downloading, though, the screen off profile kills the download rate.
Check it out, upload a file to your phone via wifi, turn the screen off and watch the speed plummet to about 100kbs!

Anyway, I had a massive power saving when I used this ROM:

Dialer
If you're using a gingerbread based ROM, it could also be the dialer. At least it is for me. Sometimes he just goes crazy and I have to reboot the phone. Apparently the dialer checks the phones proximity using the sensors again and again.
For further reference and solutions see: http://forum.xda-developers.com/showthread.php?t=1069251

Juice defender and Setcpu are in the same basket as task killers.
If you are using Smartass you don't need any profiles. Check your widgets, probably you have one which updates every second and kills your battery.

What app to use to find running apps?

Hey guys. What is the best app to find apps that are running and eating up battery? Yesterday my phone starting having abnormal battery drain when the screen is off. I lost 30% overnight! Yikes!

Just use the stock App Manager in settings. And if battery is an issue, go to About Phone, then battery and you can see whats been using it. Hope this helped

i like ZDbox app.

don't use task manager they screw **** up more then they fix, suggestion,
Find the list of safe to remove apps and remove ones u don't need, apps lik keis, mms, gmail/email, etc are constantly running, remove and replace wirh 3rd party counterparts.
Use a rom with CIQ removed, use undervolting scripts helps with battery aswell.
I can't stress this enough, DONT USE TASK KILLERS unless u know what their actually designed for.
Think of it like a PC in this sense, if you use taskmanager and kill a load of programs, depending on what u kill, can have horrible side effects, in the sense of android, when an apps not closed properly, peices can still exist in the ram.
Those peices can have effects on that, and other programs on your phone.
Your best bet for clearing ram is a reboot.
Simple, as for seeing programs running, hold home and hit taskmanager (plz keep in mind the above)
Or simply go to SETTINGS>applications>memory use and click running tab on top right.
Hope this helps. Peace

Ye there's no way it should b doin that..
10pm to 5:30am my battery drops 7-10%
@OP
2 possible solutions:
1.) Above post gut it pretty good
2.) Kernels not allowing deep sleep mode, flash a new kernel
#2 seems more plausible at this point considering your OP in full.
If its abnormal battery drain screen off ur phones not enabling deep sleep.
At this point most apps are effectively "paused" or slowed down
Making the battery drain almost irrelevant, my battery dies about 1% hourly screen off
Thanks to this mode.
Apps like SetCPU etc. Can also cause this if configured incorrectly
If using a CPU. Control app, uninstall it, trust the phone enough to do
Its own thing.
I will never recommend taskmanagers or CPU utilitys, if I did, what's the point in kernel deving besides OC?

Stock OS

Been poking around here and reading all the posts that people had mentioning battery life on stock/cm11. Is battery life really that good? I find myself trying everything possible (including hardly using the device, turning brightness all the way down, turning off bluetooth & Dynamic perspective) and I find that my phone is dropping like a brick. I can have the phone lose %s in front of me just having the screen open for a few minutes doing nothing else.
I even have two apps to optimize/kill all other apps and I'm finding that this phone is dying faster than a t-mobile pre paid LG L90 I was using prior. I just don't see how people with stock and all the features on are getting more than 5 hours battery life tops. This phone dies while you use it on the charger, which is a first from any phone I've ever used.
How do your experiences stack up? Do I just have a bad unit? Really considering going to cm11 now (really wanted to like Fire OS).

You must have something wrong with the phone. I have had Samsung S3's and S4's and the Fire is far and away the best I have experienced for battery life. I am getting close on two days on a full charge although I do not use it a great deal for voice calls.

Are you keeping Dynamic perspective off with a low brightness instead of auto? Don't see how two days is possible unless you absolutely never used the device. I can lose like 10% an hour just on the browser reading text sites.

Fire has the best battery life of any android phone I've owned. I'm on fire os with a different launcher and I have dynamic perspective on (not for home screen obviously). I'm also using auto brightness. I'm rooted with gapps installed. I get great standby time and even in use its good. You should get gsam battery monitor and see what's going on, although I think you might have a broke unit.

Here is a picture from Gsam (I don't have my phone rooted). I think this is pretty bad for only 3:28hrs of screen on time and that was with the screen at the lowest brightness, not on auto. For app usage I have 7% coming from a game I was playing, but the rest of the drain is coming from system and kernel. Would really like to see another users stats with similar screen on time, as I'm pretty sure I could completely kill this phone's battery in 4-5 hours just using silk browser on Reddit.

Your phone isn't going into deep sleep. It's hard to determine exactly what's going on there but if you download kernel adiutor (yes, that's the spelling) you'll see its locked at 300mhz most of the time. I know it sounds crazy but have you rebooted? That can often sort out a misbehaving app. Are you rooted? If so deploy greenify.

5 hours of "screen on time" is solid, the combined time incl. standby, etc. is of course much longer. He didn't know how to interpret the statistics from the device, it was a misunderstanding.

That kernel app won't help battery life but it will show you how long you spend in deep sleep.
As for greenify, you should greenify all the Google apps. I actually greenify everything except sms app, browser, phone and alarm apps.
Also, this could possibly be some kind of location based frippery. Turn location services off or onto battery saving mode if only temporarily. And turn off auto sync if it's on.
