[Atrix 4G Q&A, Help & Troubleshooting] pukemon:
Over clocking can and will shorten the life of your hw. Undervolting for overclockers is to help offset that and get more battery. Straight undervolting is for users who need most from battery and will not shorten hw lifespan, helps with with battery and possibly life of battery since current will be sucked slower from it and it heating up less.

[Atrix 4G Q&A, Help & Troubleshooting] xateeq:
so what if i overclock and undervolt at same time ???
[Atrix 4G Q&A, Help & Troubleshooting] pukemon:
You can uv and oc at the same time. It helps the temps and offsets some of the heat w/o an oc. I highly recommend uv'ing if you oc. Me, personally though, i really don't need oc, but i am trying to be patient for stable build of cyan7. I'm more than satisfied with my battery life right now so i don't want to run into possible problems you might run into flashing a custom kernel. The uv and oc might work, but wifi, bluetooth or something else could be broken and then you have to troubleshoot that, blah blah blah. If you flash a custom kernel, you should stress test your uv's and test all the features of your phone.

I voided my warranty.

I am now on 25 hours without a charge and still have 65% battery left. Previously I couldn't make it through the day without hooking up the umbilical cord of life. I used to clear apps regularly with the stock task manager but would start out with 150MB free after boot and by the end of the day could not get better than 80MB free. Everyone was crying memory leaks. These are NOT memory leaks but errant programs that cache behind trhe scenes draining your battery and stealing resources. They are also immune to the stock task killer.

I found these bad bad apps by installing Memory Booster Lite from the market. After getting a 0 applications closed I went into the Task Killer in Memory Booster and found a bunch of apps loaded into memory still! Things like Google + hogging 28 MB of memory! There was Amazon Appstore, Maps, Facebook, Beatiful Widgets, Email, Telenav, Netflix, logsprovider....all immune to the stock task killer and slowly eating memory during the day as they load. I killed all the ones I recognized (no com.XXXX stuff) and then checked back in a few minutes to see what would reload. Google +, Beautiful Widgets, Facebook, Maps, and others would reload. Using the paid version of Titanium backup I froze apps like Google +, Maps, Netflix, and others that I don't use daily. You can use other apps for this like Autostarts. I deleted apps that are not worth my memory and battery power. I also set all syncs to manual and keep the display down as low as I need to. The results were tripling my battery life. I also stay on Wifi as much as possible and as soon as I get off XDA App, Tapatalk or any browser clear it with the stock task killer. I always have about 140 MB free now.

Your mileage may vary. The display is the biggest battery killer so if your a gamer, or spend hours reading, don't expect a lot of improvement from this but you will see some. I hope this helps battery life and memory leak myths for some of you.

The important thing in this forum is to have fun and help others.
[Epic 4G General] Blankrubber:
I'm not trolling, and you do have great suggestions here. I just wish there were some easy way to get an entire day of full use without having to get an extended battery while using the epic to its full potential. I like autosync, adecently lit screen, and my range of Widgets which I use daily. Too bad I can't go more than 16 hours with everything on. I have tried at one point most of your suggestions, and it did greatly improve battery life. I suggest anyone at least give it a shot and then slowly turn back on the things they must have, like gmail sync or haptic feedback.
[Epic 4G General] KennyG123:
Blankrubber, this is a good place to add on to what I just found. The key is to see what else is running that is immune to the stock task killer. I never knew how much Google + and Maps were killing my battery. I got rid of my extended battery long ago but now I am sill amazed. 29 hours and 52% left. But the key when you say using it fully is limiting display time and intensity. No matter what that is the biggest drain so if you are glued to your phone for over 4 hours it will always be tough to make it last. Phones that used to be just phones could go days without charge. Now they are little computers. Think...laptops only go about 2 hours runtime without a charge and those batteries are a lot bigger.
[Epic 4G General] JohnCorleone:
I use Bloat Freezer myself. It shows whatever is running in the background highlighted in gray. Google+,Maps, the others Kenny mentioned are the usual suspects. Doing what Kenny said will help out for sure. Yes, its annoying we have to do this to extend battery life but some apps are always at work. Memory Booster is pretty good. Viper baked it in a ROM a while back. Its definately worth checking out
[Epic 4G General] KennyG123:
Thanks John, hard to keep up on all these apps to help manage apps and memory. Will have to check out Bloat Freezer. Hope there are less steps than Titanium to unfreeze.
[Epic 4G General] megabiteg:
I highly recommend Autokiller Memory.

After reading the dev's page and all he found I installed the app and after setting it up, its maintained my memory free of immune apps and battery life us off the hook!

[Epic 4G General] jbadboy2007:
If something is just sitting in memory why would that have any effect on battery life? It should actually improve your battery life cuz then it just loads the app from memory and not a full re open of the app. Now if your saying that these questionable apps are just running processes then yes that would have an effect on battery as it is just sitting there doing something. But back to the memory side of this. Memory is used in all devices to take some of the load off the processor to make it load faster. It is there for a reason every device would not use memory if it was not efficient at loading apps and saving battery.
[Epic 4G General] KennyG123:
But if you only use the app once a week or so why waste those resources or the initial load time. If it sits in memory and another app needs that memory the processor uses more power and battery swapping apps in and out of memory needlessly. My phone is super fast and running 32 hours with 46% left. I can't put up a better argument than those results. Memory swapping is bad on battery it seems.
[Epic 4G General] JohnCorleone:
I button to press to unfreeze with Bloat Freezer....actually 2. You press menu softkey then unfreeze all. The phones baked in apps are in red, running apps highlighted gray, and frozen apps blue. Its really user friendly
[Epic 4G General] Zeinzu:
1: you must never actually use your phone at all, if you do then your battery claims are bs

2: you obviously don't understand much about android/linux and how memory functionality works
[Epic 4G General] KennyG123:
Whatever dude. Look at my posts count and thanks count. Got this phone a week after it came out in September and never could get better than 16 hours life out of the battery. I do a few simple things as posted and am at 38% with 32 hours. Obviously you are the one without a clue. Troll out of my thread if you have nothing constructive to add. Believe me or not I have nothing to gain by posting this.
[Epic 4G General] megabiteg:
I've been around the Android platform for more than 3 years. I've pretty much read all google has shared with us (the Military) for application development and I do agree that there are dormit services that hog up your memory / battery even when your not using the phone.

I agree with this dev and his tool: http://andrs.w3pla.net/autokiller/details

I think that he nailed it when he found out how did Android manage memory and the determination it takes in order to "kill" what you don't use.

Now... Do you care to share what you know about the subject that we don't, in stead of just coming bashing and leaving?

This is a forum, we are more than open to debates here.
[Epic 4G General] omair2005:
the v6supercharger fixed these issues for me. also if you use go launcher, there is a tab in the app drawer of running apps which you can close with ease!
[Epic 4G General] kobby2k6:
that's the app i use...i only kill the apps that don't close properly after i use them and frozen some services with titanium...i have amazing battery life (eco5 btw, gingerbread is not stable enough for me)
[Epic 4G General] ralf_97:
Tw wats ur onscreen time?? Would u post some screenshots? The longest battery I ever had was like 15 hours and 4 hours of onscreen time with around 10% left :)

[Epic 4G General] corythug:
+1 for V6, im usually at 250mb free ram consistently, while closing NOT A DAMN THING :D
[Epic 4G General] KennyG123:
For that basher out there, I am sorry if I don't spend hours watching porn on my phone for you to really judge battery life but here is the pic:

And I may not be able to code Android but I am familiar in C++ and CPU usage and how much you lose by not having available memory to swap programs with.
[Epic 4G General] KennyG123:
Nice. That was my issue though is that some of these memory/battery killers don't show up in the launcher's task killers. Google + and Maps never show up and get stopped and continue to kill the battery getting data behind the scenes because Google wrote them in that way. It is important to at least check if you have bad battery life what else is running with a good task killer like Memory Booster Lite.
[Epic 4G General] kobby2k6:
i think the best solution for battery life is autokiller, v6 script and titanium..the stock gingerbread task manager aka (the running services in settings) isn't that great...when i was on eg22, i noticed it displayed the wrong amount of ram left and didn't display every single app running in the background..autokiller is able to see every single app running in the background but never kill the programs with (com.google and android.process)...I only kills apps i use like engadget and pulse..when u exit these with back button, they always stay in the background and use autokiller to make sure it's completely killed...never set any task killer to autokill apps, that will drain your battery faster...and they are some annoying 3rd party apps that always run in the background since they are not coded well (imo)..for example, i froze the script manager with titanium after i implemented the v6 script because it kept restarting itself all the time..i suggest people follow RandomKing's tutorial on how to extend battery life, it helped a lot..http://xdaforums.com/showthread.php?t=1106524...i constantly have 150 to 200 ram free with im not running any apps..im on eco5 aosp rom with eco5 (eg22 and eh06 are not stable enough for me)
[Epic 4G General] Bobulus:
To be honest, I think you're overestimating the effect these task killers are having on your phone.

Your graph looks very similar to mine when I'm using it moderately, and I haven't installed any task killers. (And, yes, I've got the same Maps, Google+, etc apps on my phone). The only changes I've made are:

- Turning my screen brightness all the way down.

- Having very few non-push syncs.

Today I'll be using my phone a lot as a camera, but I'll try to remember to leave it off the charger one day this week so that I have a power graph that lasts longer than 18 hours.
[Epic 4G General] KennyG123:
Good stuff Kobby, thanks.
[Epic 4G General] KennyG123:
Thanks Bob. I really thought before this that anyone getting better than 24 hours was BS until I killed all the crap that I never knew was running and the stock task killer had no control over. Your input is appreciated and i am now on 32 hours and 32%. I figure I will be able to make it until bedtime at 11 tonight which is crazy for my phone. I admit I know being on wifi most of the weekend probably made most of the difference but still is amazing to me.
[Epic 4G General] KennyG123:
Final numbers before bestime and putting on charge was 37 hours and still 17% left. Spent quite a bit of time on the XDA app in the last hours too.
[Epic 4G General] JohnnyEpic:
I read thois site quite often. Don't really post much, mainly because of post like this. Having a stressful morning, so, I thought I would just say, that this post is worthless, and you are a jerk.
[Epic 4G General] dwyw42:
A question to all those that say this procedure gives them a big improvement: when you had poor battery life, did you have the OmaDrm service killed/frozen? It's a known battery killer and I get similar battery life (36-48hrs between charges) with only that frozen.
[Epic 4G General] rando991:
The other big one is if you had removed the stock Feeds & Updates widget (the pink one), and didn't freeze or stop the SNSService, your battery will suffer once it starts a "restarting" loop. Having a service in an endless restart loop can suck the life out of your battery in double time. Either leave the widget on the desktop or kill the service.

@kennyglass123

Did you try using the new version of Chainfire 3D to save your battery? I use it now, nightmode on it minimized my display drainage. I customized nightmode to tune down the brightness more than the system could. My phone lose about 4% of battery every couple of hours
[Epic 4G General] jbadboy2007:
Ill add my 2 cents. I've only tried autokillers briefly never experienced any real gain with using those. I do believe every once in awhile you can get a rogue app that is just drains the crap out of your battery and sometimes it is one of googles services. But what I do to fix this situation is toggle my sync off then back on and it seems great again. I get a minimum of 30 hours per stock battery. I have 4 stock oem batteries. I always have atleast 3 hours screen on time, listen to pandora, play lil games, sync is push to 2 accounts never turned off, I email a lot sometimes 50 emails or more a day. A few texts a day, a few phone calls a day. I've never had a problem with battery life since I've got this phone about a year ago now. I think most battery drainers other than screen are crappy apps. I only keep apps on my phone that I use pretty regularly. I have 36 user apps lol that keeps the memory usage down no need for auto killer. The only way you should see 16 hours is if you are either constantly roaming or you do not put your phone down at all.
[Epic 4G General] KennyG123:
Wow...all great tips everyone. And yes I had DRM services stopped with Autostarts a long time ago so this is new savings. I think the 2 biggest killers were Google + and Maps. I think I had deleted the feeds and updates widget a while back. Just deleted Beautiful Widgets with weather which may have been another drain.
[Epic 4G General] nikon120:
Yea my phone wigs the hell out when I freeze anything to do with DRM and System Updates. Back on DI18, I'd just leave them active and kill the OMA process with each reboot. On EC05, I'm not effected by the drain of DRM, but I kill the OMA process anyways.

Strangely enough, using DI18, Wifi was my battery savior. Now on EC05, Wifi completely destroys my battery life. I hope Gingerbread will fix that issue for me. :confused: I've ODIN'ed multiple times and still same Wifi issue, so I just stay on 3G.
[Epic 4G General] darkpoe:
The real killer is having to run programs to speed up or save battery life.... less should be more..... the real problem is we shouldn't have to do this
[Epic 4G General] a2tz:
So kenny...question for ya. When you froze the map service, does that mean you don't use maps at all? I see it running in there, and would freeze it but I use the map all the time. I don't need it running all the time....but don't want to be able to ever use it.
[Epic 4G General] JohnCorleone:
Yeah, if you freeze it, you can't use it. Kenny is right. Maps, Google+, and Beautiful Widgits crush my battery. I haven't used Beautiful Widgits in months because of this. I am going to freeze everything extra that's running today and see if it helps me today.
[Epic 4G General] corythug:
Plus 1 for batter dran wth G+ and maps, although I've never had a problem with beautiful widgets. I am using the 4x1 superclock as opposed to the giant superclock most use though. Don't know if that makes a differnce.
[Epic 4G General] KennyG123:
It only takes me a minute to defrost an app if I need it. I have been using TeleNav because the speech is clearer and the road lines are a little thicker and easier to see. I haven't tried John's suggestion of Bloat Freezer yet which sounds like you can unfreeze apps quicker.

Android System 80%

I read through the forums and still cannot figure out why my Android System is taking up most of the battery. Has anyone had this problem?
[Epic 4G General] rando991:
Yes, and I have rooted, frozen or deleted all different kinds of apps, make sure I'm logged out of FB, GTalk, etc. I use ATK and kill off most things (I still want to get texts and stuff), turn off all GPS, 4G, 3G, BT, WiFi, Froze DRM, SNS, stock Gallery, AutoSync, Background Sync, Location, and still get battery leakage where phone doesn't want to sleep. Spare Parts will only tell me Android System and "0" is using most of the network (don't know why). I have to reboot to force it to sleep when I turn off the screen. My wife doesn't not have this problem, but her phone never got the OTA to EB13, she went straight to EC05. I wonder if that interim corrupted something. Anyway I'm not yet on a custom ROM, still trying to decide which to use or just wait until a custom EH17 or 18 (whatever they are up to now) comes out.
[Epic 4G General] KennyG123:
Because it's suppose to? Everything your phone does goes through the Android system. That is like asking why Windows is always running on your PC.
[Epic 4G General] hayzooos:
I wouldn't worry too much about network, I would be concerned with the 'Partial Wake' listing in Spare Parts. That will tell you what's keeping your phone awake. My guess could be the Gallery. Get rid of it and use QuickPic instead. It's better and it doesn't have the possibility of keeping your phone awake.

The next thing you could try would be to Odin EC05 and get off EB13, if you're still on it. There are some great EC05 ROMs out there, I would strongly suggest giving a few of them a shot.
[Epic 4G General] turkaloo:
Oh, ok; then why when I see other peoples battery usage screen shots their Android System usage is the lowest out of all of the categories?

They are just "kind of" running everything through the Android System? I'm just trying to see if I have something running all the time that shouldn't be thats all.
[Epic 4G General] KennyG123:
If you have the display on all the time or something else is using a lot of power it will be listed higher. If you are a little to moderate usage person your android system will be the highest. Mine is at 83% currently and have used my phone for maybe 30 minutes out of a few hours. If you really want to verify your phone is not using excessive battery get CPUspy and make sure that your phone goes into deep sleep while not on charge or being used. Also OS monitor to see what apps are using your battery.
[Epic 4G General] turkaloo:
Thanks for the help
[Epic 4G General] rando991:
Hayzooos, I have checked Partial Wake when it does this and there is nothing that sticks out. Each item in there only has been active just seconds, not minutes (at least that's what Spare Parts says if I'm reading those correctly...usually Android System, Dialer, and UID 10013, then sometimes Maps, Voicemail, and Clock...but like I say, if I select each one the total times don't add up to the amount of time it's been awake). Also, I haven't deleted Gallery, but I have Bloat Frozen it and yes I do have QuickPic. And yes I am on EC05, but no custom ROM just rooted. I mean't that I got OTA to EB13 then to EC05. Any idea?
[Epic 4G General] hayzooos:
Huh...sounds like you have your bases pretty well covered. I don't know how long you're leaving your phone on before checking things in Spare Parts, but I would use it normally for 4-6 hours, and see what Spare Parts says after that amount of time.

EDIT: The only other thing I can think of is maybe your phone doesn't like the EC05 modem, which I'm assuming you're using. Regardless, you could try a different modem and see if that helps. I got good results with EG22. I'm now using EH06 but the 3G speeds royally suck on this. Thankfully, I'm in a 4G area about 90% of the time, and the other 10% I can use WiFi.
[Epic 4G General] KennyG123:
Well the Epic will still be available through October and refurbs long after that. It does sound like you have your bases covered. What is listed in settings>applications>running services? I am assuming it is still unrooted since you stated it was 9 days old. I think Spare Parts requires root to see what is using your battery. It may be a bad battery and since it is new Sprint should just pop in a new one for you for free to try it out. The apps you have downloaded...none are any social networking like Google + or Facebook right?
[Epic 4G General] nismology:
Just thinking aloud here....my thought on the matter is that some of these OE batteries are just plain tired, or getting there. Over a year's worth of charge/discharge cycles will reduce any battery's capacity, regardless of "size". Were I to keep my epic, I'd just buy a brand new Samsung battery for the next year of usage and go from there. Just a man and his thoughts........
[Epic 4G General] KennyG123:
@prfella....it probably was a conflict between Juice Defender and the Power Saving mode that was causing the excessive drain. A battery draining fight for control. Glad you extended your battery life. Did you also check what is running in your running services under applications in settings?
[HD2 General] stealth21:
Hi everybody..

As it is a general problem i decided to write my complaint in here, All of the operating systems have the same problem.

Lets start from the beginning.

I'm a 2 year (almost) HD2 owner.

I've used my HD2 WM 6.5, and after a long long time just tried my first android release. Core droid, and then cyanogen 7.

I never had problems while listenning music in my device.

But always had complaints about my battery life. It is consumed at the end of the day at minimal usage.

I did flash 2.14.50 to my device which had 2.15.50, from my latest original rom (3.14), just to try my battery consumption. I saw no diffrence and then back to 2.15.50.. in the tri colour screen.

And then I decided to try WP7!

Everything was fine till i realised that i cannot listen music.

Application stops and pauses by itsself. means that music interrupts anytime, anywhere no matter if i press buttons or not. Its so annoying!

Some people on the forum told me that this using speakers instead of headphone might be the origin of the problem. But the problem exists with my newly bought headphones. So thats not it!

I dont know what to do with my phone right now.

When i play a song using androids stock music application, songbird starts by itsself and ruins my whole joy!! overlays my songs, something stops my songs triggering something in the background. Intresting things going on at the background.

I need to find an explanation for this.

Explanation and a solution. Because i dont want to carry my old ipod anymore

Any help would be really appreciated.

Here is a post that i sent yesterday about this problem yesterday in cyanogen topic.

http://xdaforums.com/showpost.php?p=16840840&postcount=16325

Wireless - wifi problem should be, a "radio unit" problem i think.

The whole thing started with my radio unit upgrade :(
