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.

Easiest on the battery? I love sky raider and that's what I'm using. I've restarted my phone fully charged 4 hours ago and now I'm down to 15% battery life. I'm very disturbed by this. I made a few phone calls, surfed the market, searched the web for phone listings, used my tapatalk, and took a few photos, but goleee!! 15% after 4 hours?! Sheesh! I tried recalibrating my battery updating the kernel, (runing kingx2). I'm seeing on youtube and here on the forums about people boasting about their improved battery life but I just can't seem to keep up. As I'm typing I've bumped down to 12%. This is ridiculous. Any suggestions?

Uhmm. Well, the ROM has almost no affect on battery life. Battery is mostly used by Radio and kernels.
You need to give us more information.
Are you Over Clocking/Under Clocking?
What Radio do you have installed?
Are you using an Auto-killer?
Have you ever tried to bump charge your phone?
Did you clear your battery stats after a full charge, then reboot?
I think its kind a funny you even have to bump charge in the first place. I still am amazed that my Droid 1 gets 20 hours+ of battery life and my Droid Incredible is lucky to get 6 hours.
I am on UD 8.0 right now trying it out as Skyraider destroyed my battery.
Do you have to bump charge every time or just once?
Does reseting your battery stats fix anything?
What ROM + Kernal would you recommend for good battery life?
I am on radio 2.15 no auto killer.

Is that the BFS #2? If so, I'm at a bit of a loss, but it's worth mentioning that overclocking is pretty harsh on the battery. I underclock.
From my experience the rom does have an effect on battery.... there are many things in the rom and how it's setup that do in fact effect the battery usage.
With that said, stay away from cut, copy and paste roms like UD.... pure trash.
I'm getting about 10-16 hours from my inc with minimal usage. Running froyo 2.2 latest leak with the latest radio.

That is your problem right there. Aggressive auto killer? Jesus every time you do anything with your phone, whether it be starting a new app, sycning your gmail, or even turning your phone off, your CPU is going full blast overclocked killing every possible app and service. This will drain your battery. I bet it is the main cause. I bet that your task killer is killing an app or service, the app is restarting itself, and it kills it again... therefore draining all your battery.
But then again... if this didnt happen before, then i dont know. I still think task killers should be used very minimally only when your phone is running really sluggish and you know you have several apps running that you do not need.
The Rom has minimal effect on battery same goes for autokiller. Apps kill you battery, change governor in setcpu to conservative. Create a profile for screen off CPU min/max 245. Check your sync settings I bet something is syncing often or stuck in a continuous sync.

Since I've been letting it sit, cell standby has taken over along with phone idle. Prior to that, my phone was running pretty hot. I deleted batterystats from root explorer a few hours ago so I'm letting it drain again. Plus now I'm using my eris battery which has ran alot of cycles of drain & recharge. I'll bump down my task killer tho.
Sent from my ADR6300 using Tapatalk
As has been said, the absolute best way to make it through the day is set a profile for 245 when your screen is off. I underclock using hydrakernel 1 at 652 full time. I never need to use the maximum 1152 for anything practical.
The other suggestion is going with the seidio 3500mah battery. Sure you'll have a heavier bulkier phone, but people have gone upwards of 5-7 days on a charge. And also people state that it feels better in their hands. There is also a 1750mah battery that won't require an extension, and an official HTC battery at 2150 (but also requires an extension).
I honestly think HTC and Verizon screwed the pooch on the battery issue. I'm sure they were thinking extra sales on extra batteries, but at the cost of customer satisfaction.

Several of the more knowledgeable devs has said deleting your battery stats is useless, maybe even counterproductive. There was a thread in general about battery stats that several devs chimed in on.

Are you using task killer or autokiller? If you are using task killer get rid of it. Also Android system using your battery means its not sleeping right something is keeping your phone awake. It shouldn't be hot when screen is off.
I have a similar set up. King3 @1113 and skyraider3 I get about 10 hours of heavy use. I turned every sync down to once a day except weather @ 3 hours. The conservative governor and screen off profile with max/min 245 governor powersave. Will make a huge difference.
sent from my Incredible via skyraider & tapatalk
Yes that's awesome. Before reading your post I figured I should do a sleep profile. I turned off my syncing except weather. And battery life is slightly improved. I still have auto killer though. I set it to moderate. In at
29% and I been running it since 130. But not bad after watching a video and listening to a few songs and going back and fourth with a few folks on sms &a few phone calls. So should I still get rid of auto killer?
Sent from my ADR6300 using Tapatalk
I like autokiller. It's a min free utility. It should have no negative effect on battery. All it does is tweak the OS to be a little more aggressive on killing tasks as needed.
Also note that streaming especially over 3g is going to drain your batt. Videos will also drain it pretty fast.
sent from my Incredible via skyraider & tapatalk
Tasks fall into two categories: running and idle. Most tasks on the system are idle and are not using any battery. The tasks killing your battery are the running ones.
Examples of running tasks are;
Android system
HTC Sense
Any active widgets (clock, weather)
Any auto-sync (news, weather, facebook, twitter, etc.)
AND autokiller
Autokiller is constantly running looking for tasks to kill, using up the presious battery you're trying to save. Plus if it kills an idle task that you're going to need later the system just has to go thru the overhead of restating the app.
To confirm whether or not autokiller is using system resources, get app Android System Info from the market. Run it. Switch to the task tab, then hit menu and change the sort to CPU. You can see which tasks are active and using CPU/battery.

Yes when you look at cpu usage the Android System Info app does use the most cpu. But this is only because it's running in the foreground at that moment. Once you exit the app it doesn't run continuously in the background like autokiller does.
Did you determine how much cpu was being used by autokiller?

Many are using the dopio kernel found in the dev section and setting the main to conservative, then creating one profile that sets the cpu at 245/245 when the screen is off. I have also seen/used a free app "juicedefender" that in theory looks helpful. Unfortunately, I suffer from obsessive ROM updating disorder and cant speak to how effective these methods are as my constant reflashing and rebooting destroy battery life.

What rom are using? My wifes phone is running cm6.0.0 and when I checked this morning was over 2 1/2 days uptime and 42% battery left.
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?
My battery is draining like CRAZY and i cant seem to find out what the issue is. Ive tried calibration several times and using a task manager that turns off running apps every few seconds(which seemed to make it worse) and that didn't help. Auto updates are turned off and fbook is only set to update every hour and brightness is set to minimum yet my battery only seem to last 8hrs. please help. i would really like to pinpoint what the issue is.
Oh...im running ERA Legendary 2.1, CPU speed and voltages are stock
That screenshot is worthless. It doesn't show anything useful. Percentages are meaningless. Get Betterbatterystats to see what is running as far as processes and partial wakes. Get CPUspy. To make sure your phone is going into deep sleep. Get Memory Booster Lite to see what is using your battery and get rid of the auto task killer. That will kill your battery fast.

i only posted the screen shot to show the time vs percentage. i already got rid of the task killer and here is a screenshot from better battery stats. idk how to stop the processes though...
Again the percentages mean nothing. In Gingerbread everything goes through Android system so it will always be highest. If you use your phone only an hour or two a day then it will drop to around 60% with cell standby getting higher. They will always add up to 100% whether on a minute or 10 hours.
You didn't post the partial wake locks screen. Also did you check CPUspy for deep sleep? Did you uninstall the autokiller? You can go into settings>applications>running services and stop applications that shouldn't be running like Facebook or music and video players, etc. Sometimes it's best to get an app like Bloat freezer and freeze apps that keep reloading if you don't use them often.

Another question and maybe the most important...what is your screen on time? I didn't see it in the screen shots. I think Max screen on Time I have gotten is right around 4hours. All the battery tweaks in the world wont help, if your screen is on a lot. Also...make sure to freeze drm, sns and system updates. Use randomlking's zip file.
If none of that works...wash, rinse, repeat. Wipe clean and reflash, rom and kernel.

As I'm sure you know, everyone's battery drainage is widely independent. However; I'm on "stock" Legendary 2.1 and recently with the updated Samurai kernel as well and run Juice Defender Ultimate. I've got some advance settings set but over the past 3-4 days, I average about 20 to 22 hours on a single charge.
My usage in an average day is: about 20-30 texts, about 10 minutes of phone calls, 10-12 emails in and out, 10 minutes of web, whatever app updates there may be and maybe about 15-30 minutes of light to medium use games.
If JDU is something you might want to look into, I would be more than willing to post my setup to get you started. <--For some reason, people are real stingy with their JDU settings.
This kinda thing just happens sometimes, and usually clears up on it's own. Especially common after flashing new software.

i ran these through my seat-of-the-pants benchmarks, are there any other for these sorts of apps? , and can't tell any difference. the biggest difference maker that i have noticed is Titanium backup and freezing as many progs as i could and a better launcher.
i tested the phone as it initially came out of the box, removing the apps i could via app manager.
next, i ran it with JDU for ~4 days.
Then i ran Tit backup and froze many more apps and ran the phone with JD for 3-4 days.
then installed Ram Manager Pro and ran for a few days, then uninstalled JD and Ram Manager by itself for a few days
and finally uninstalled both, factory reset my phone, ran Tit Backup freezing everything i wanted and am now running that config for several days.
i can't see any change in battery life or perf between any of these.
what's your experience? did i miss the benefits? is there a more scientific way to test these apps on our phone?
I could be missing something, but my understanding of Ram Manager is that it controls how the cache works (RAM cache that is), aka, how previously opened apps are being handled, how long they stay in ram, or/and how often ram getting cleanup, etc. So theoretically there shouldn't be much of battery improvement with that app, only the performance on common used tasks.
As of Juice Defender, I've tried once, and realized it's not for me, I use push mail and listen pandora radio most of the time, it requires internet all the time. But in theory it should significantly save on battery if you don't use phone every second minute, cause it turns off everything and only turns data one every so often to check email, news, etc.
I guess it depends how you use your phone...
Have you tried SetCPU or such?
I use SetCPU to change CPU frequency, set min to 190mhz and max to 1500mhz, and max to 190 when screen off, yesterday with minimum phone usage in 7 hours used up 15%
And I wonder, by default, does Nitro set CPU to max and keep it that way or it also uses scheduling and changes speed as needed?
But I can tell you for sure, the network (HSPA+ here) usage uses as much battery as the screen, if not more...and network through WiFi saves on battery compare to HSPA.

that's my understanding of Ram Manager as well. but i didn't notice any perf changes in how fast apps open, close or switch v a Titannium freezing showing good results imo for that sort of thing.
i listen to slacker/pandora but it's mostly via wi-fi, so i was able to configure JD to keep the wifi on and turn off all the other radios but that didn't seem to provide me any benefits.
i have not tried setcpu but will def check it out, thx for the heads-up on that one.
re: network, it doesn't even show as a battery drain on this phone and i am in an LTE area, the 4glte status signal is always on. i was under the impression it was a massive drain, maybe the phone searching for a lte signal is the drain but once it finds one and locks on maybe it settles down. i have no idea but it's not on the list of what's using the battery.
Ram Manager Pro has several settings (Balanced, Balanced-More Mem, Hardcore Gaming, etc...). Did you try any of the others? For me I noticed improvement, but perhaps it's also because of the way I use my phone and that Ram Manager is more suited to my ways and habits... Or maybe it's just placebo and I'm drinking the kool-aid.
For Juice Defender Ultimate, I will say probably one of its' biggest capabilities is locking down the apps that turn on the radio for background updates. A definite battery drain for folks that use a lot of social apps as they compound the use of background updates. I personally turn-off ALL background updates except for mail. So JDU wouldn't tremendously help me.
Lastly, I completely agree with [email protected] about SetCPU. I don't know how the OS handles the frequencies but one of the biggest battery savers is definitely using SetCPU for dropping the min/max CPU speeds to minimum levels when the phone is sleeping.
I installed setCPU and it instantly created a laggy interface. very very noticeable. HAs anybody else tried this app with this phone?
Had this same problem. I actually switched of all apps. The phone on idle does not loose that much juice. Overnight I maybe loose 8-10%. I turn data off at night using Tasker.

update
I've still been farting around with these apps, going back & forth between using them and not.
best I can tell ROM manager provides ~5% increase in ROM management, which is pretty good for a couple bucks eh.
JD is so much harder to gauge/compare. I think it does defend the juice but I can't tell how much. The one thing I do not get about the app is how it continues to show increased battery savings over the previous 48 hours. I can see how this works when the app is 1st installed but at some point over time that number should = 1 right? JD can't keep stretching battery life 1.5x over its own management system.
scott0,
You're right, unless there's some heuristics built in (probably not).

Anyone using a good stats widget that would show mhz of cpu/baterry/ram?
Something light that would not eat battery. I used the one that came with antutu cpu master but that caused more problems.

Just out of curiosity, do you have to be rooted to use Juice Defender? When I select the app in the market it tells me "This item isn't available by your carrier."
Are they telling me that AT&T has blocked a power saving app?
