[Q] Average Battery Life/Usage?? - myTouch 4G Q&A, Help & Troubleshooting

Hey all, I would like to get an idea of the average/normal battery life you are all getting with the TMobile MyTouch 4G. I'm originally a proud owner of an HD2 & also own a Droid Incredible, but a family member has this new Tmobile phone & they are not having the best experience
Basically, Battery is running out, literally from 100% to 0% in approximately only 5-7 hours. What kind of use? Almost none! 3G Data On; GPS, WiFi, Bluetooth all Off. No navigation. Less than 3 hours talk-time during that time. Display on Automatic brightness, with timeout at 15 sec.
She is at work during most of this time so no heavy data usage, & I know so because she's on the 200MB plan & "MyAccount" reflects light data use.
Phone is completely Stock (no overclock, stock kernel, not rooted, etc).
So is this terrible battery life normal? Or would you all say there is something off with this particular phone?
There is a task manager installed set to kill unnecessary apps on screen off. I've gone over all settings at least 3 times. Still dies in less than 7 hours. I dont get it. So that's most of the info, anything else I forgot to clarify let me know!
Thanks!

If you turn off the mobile network and stop all synching if you don't need it the phone should last you a very long time, the data connection saps up a lot of battery.

First of all, UNINSTALL your app killer. It does more harm than good.
Second, it would be good to root your phone, and uninstall unnecessary apps. (amazon mp3, games, etc etc... all the bloatware.)
Third, install setCPU from market and set up profiles as recommended on XDA. (search)
Fourth, set USB debugging ON, stop all sync incl background data, display at auto brightness.
YOU have to remember that battery life really depends on usage, and LOCATION.
During a work week, I recharge battery before I go to bed and unplug @ 100%.
I usually get one day of battery during work inside a building with E (not H) so not so strong signal. I make ~30 min total call time with ~1 hours of web browsing, market app install, stocks, etc... I get home with ~30% left.
During the weekends, I rarely use the phone sometimes and get 2 days or more.
Currently at 1d 3hrs and still 55%.

how do you uninstall the preinstall programs? i rooted my phone.. but when i go in to manage my apps.... i can still only unintall the ones that i downloaded. the preinstalled ones still dont allow me to un install

Use Titanium, or another uninstaller from the market...

Don't uninstall system apps with titanium. Use the freeze function first. Arbitrarily uninstalling certain preinstalled apps can make your phone go wonky and titanium does not back up system apks, only data. So if you uninstall a system app, it's gone for good.

On stock you should probably be able to go a day without the phone dying, depending on usage. Good custom ROMs with SetCPU profiles can do even better.
My advice, don't fuss around with trying to figure out what can be uninstalled and what can't. It's far easier to flash a custom ROM that doesn't come with any of that crud to begin with. If you're rooted, you might as well. Just make a backup of your stock ROM in case you need to switch back to it for some reason.
If you aren't going to do that, then I agree with the above about nixing the taskiller. Get a program that lets you monitor apps on your phone. Check it after a while and see if there are any apps that are misbehaving (using more resources than they reasonably should), then you can uninstall the offending app.
Naturally, turn off wireless and GPS when not in use. You can turn of sync as well, but every now and then you should turn it on for a bit to sync your stuff with Google's servers.

I unplug my phone around 6am every weekday and usually plug it back in between 10-11pm. My daily usage consists of mostly txts, a few phone calls, web browsing and maybe a game or two.
When I plug it back in every eveing I average about 40% battery left. I leave bluetooth and gps on and have all my mail accounts sync every two hours.
Compared to my Vibrant and even my G1 that is fantastic. The last couple of days I left it unplugged overnight to use as an alarm and it lost very little of it's juice.

I have a stock (though rooted) MT4G that is about a week or so old.
I use my phone moderately, but only talk maybe 10-30 minutes on average. I use between 30-60% of my battery in a 16 hour period. Once or twice I have used 2-3 hours of talk and heavy data useage, and I don't think I went under 25% battery in 16 hours.
It sounds like something is amiss with your family member. What does your battery usage stat say?
I would guess you may have a defective battery....

I've had my MT4G for about a month, still running stock and not rooted (yet lol). I've been paying attention to battery too. Battery life seems to have decreased over the last couple of weeks. First couple of weeks I had the phone it lasted from wake-up to bedtime on a single charge. Recently, though, it is usually at 10-20% by 6pm when I get home from work. Minimal usage, a few short phone calls, some texting, regular e-mail checking, and just playing with it for an hour or so every day (customizing home screen, market browsing, web browsing etc). Used to be when I'd plug it in to charge before going to bed it would be in the 10-20% range, now it's hitting that range about 5 or 6 hours earlier. Frustrating to say the least.

Just to give you a bit of reference, when my phone was stock unrootedi would get about 12hrs on a charge. After rooting I did a few simple things and now I get between 24 and 36hrs on a charge. The things I did after root were:
1.Keep gps, bluetooth, and wifi off when not in use
2.when at home using wifi, I change the carrier mode to gsm only so the radio doesn't constantly search for cdma signals. (this eats a lot of juice).
3.keep sync off and only sync mail when I need to check it.
4 don't use feed widgets (fb, twitter, news). I use the apps for those needs.
5 keep my screen brightness at 30% unless I'm in bright sunlight. I rarely go over 60%.
6.used titanium to freeze unwanted or unused apps and widgets.
7.use setcpu to underclock when screen is off or battery is low.
8.use watchdog to monitor cpu usage of my running apps. It notifies me if an app goes over a predefined threshold.
9.I NEVER use a taskkiller.
10.I don't use live wallpapers (watchdog has confirmed that they are ALL cpu hogs)
Some of these practices you can do without root and are good habits to get into.

Battery Life?

I've had the HTC Aria for about four days now and my biggest issues is the battery drains to quickly. At first I attributed it to use because android phones prompt you to use them more often. However, even without use it still drains pretty rapidly. Does anyone know of a solution to this issue software wise. I have already turned off Bluetooth, GPS and Wifi. Are there other solutions
I got mine on Saturday, and I've actually gotten pretty good battery life out of it. I'm still in the habit of charging it every night, like I had to do with my old WinMo phone, but I think I could probably go two days without a charge. And that's with GPS / data always on, Wifi parts of the day, and pretty heavy use, since I'm always playing with it.
Have you tried something like Advanced Task Killer to keep apps closed that you aren't using? You can also adjust your screen brightness and timeout to try and save power.
It says that of my power is used by cellular idle or something like that 50% of it was used by that. Could it be my AT&T service
I don't get more than 10 hours out of mine. When I know I will be out all day, I turn the screen brightness almost all the way down to help conserve energy.
Good as it Gets.
With basic usage (some texting, a few calls and some market browsing or playing a game here and there) about 2 to 2.5 days without charging. Maybe the ones having issues with there phone sucking battery have to many widgets running.
In my current configuration I am only using 3 of my screens and only 3 widgets [favorites (small one), HTC clock/weather widget, and the HTC calendar widget (small)]. I have my work email checking every 30 minutes for syncing. I also have gmail and the default mail app pulling mail. I run ATK but only to kill apps on startup (cause it runs almost everything), other than that you don't need a task killer as you will have to reload these tasks next time and that will drain battery. I don't use it after that to kill anything. I am also running my screen at about 30% brightness.
Just some tips, widgets are nice, but they suck the battery life as well as constant updates. Check to see what you are running and disable/remove what is not needed or adjust sync times.
My battery life is fine. I got two days over the weekend with light usage. You need to look at what services are running and disable any widgets that you dont need. You may also want to look at the sync settings and turn off things you dont use (such as news). You do not need a task killer.
Also, see this post:
cranked said:
some quick tips:
1) disable market notifications - Market -> Downloads -> Notifications -> 'Don't Notify Me
2) Lower the sync times for your social network apps like twitter and facebook (or make them manual)
If you still suffer, have a look at some of the great tips HERE on the Cyanogenmod forums...ignore 1 and 3.

Also one might do *#*#4636#*#* then change phone setting from WCDMA to GSM .... Then that get little more out of battery...
It's critical that you turn off auto-sync; I have found that it absolutely destroys battery life.
Before I was losing maybe 5-10% every hour on standby, but ever since turning off auto-sync, I'm still sitting at 100% battery after 5 hours of standby.
Turning off mobile data/Wi-Fi doesn't make an impact on battery life, in my experience.

I edited your response..
Auto-Sync in itself is not going to be a problem.. Depends on what's syncing. EVERYONE will have different battery life because everyone uses their phones differently. Different configurations, different accounts used, different amounts of traffic on those accounts, not to mention actual usage patterns.

90% of people will have *slightly* different battery life.
5% of people will drain it fast.
5% will use it like a voice phone and might even get 16 hrs out of it.
But to turn off all apps makes for an invalid test because then you're testing the phone as if it were a non-smartphone, like a voice only phone.
I think the battery is too small for me and probably too small for most people. I look forward to fat batteries for this great phone.

My wife gets 2+ days out of hers... The battery is not that much smaller than my Nexus One, a more powerful phone, and I'm a power user with a lot of crap running including IMAP push mail, weather syncing... I look in at Market, Facebook, Twitter and manually sync those types of things etc.. I can easily get a full day out of it, off charger ~8am back on the charger midnight, 20-30% left. What I don't do is sit staring at my phone all day or play games for 8 hours at work, nor do I use it as a mp3 player..

I dont get it........BATTERY DOESNT LAST FOR ****!

So i noticed on my stock battery i get about 10 hours of battery life, when im really not even using it at all besides checking it on my breaks or lunch. For instance i had a full charge at 4:07 pm , disconnected and now have a 70percent charge at 5:44..? really WTF is going on with this phone..? I havent done **** on it but browse. I even bought the verizon extended battery and that thing doesnt last as long as i thought, it dies down in about 8-10 hours tops as well.. Is there something im missing here?
I dont run gps often and neither wifi or bluetooth. Just texting and getting online every now and then....
i do have advanced task manager and do notice almost every program running all the time although i kill it when the programs when i jump on my phone....is this normal? wtf is going on with this thing?

Check for things updating frequently like twitter. Also don't kill them apps they will restart using battery to start it. Just let them run, they actually hibernate till needed.. don't close them.. that's probably killing your battery.
There is a lot of bloat ware that runs in back ground unless you root and uninstall. That is the one think I hate about these phones. I wish I could uninstall the bloat ware with out rooting. Anyway download advanced task killer and set it to kill programs whenever screen is blank. It will save some battery life. I get a day out of mine easy and I talk for at least an hour text at least 20+ a day, have it auto check every 5 min for 2 emails and have quite a few widgets running and surf at least 10 minutes...
I was really hating the battery at first. So much that I bought two non oem batteries from ebay. However, since I rooted AND loaded leaked froyo AND loaded deodexed, re rooted froyo leak through koush's recovery, I am getting through the day with 30% or more when I plug back in at night. The only extra charge is in the car dock for 30 minutes on my ride home from work. Try those steps, and rename bloat. Get rid of atk. I get much better battery life without it.
Just my experience, hopefully you figure it out. I'm a fairly heavy user and love this device.

I have had battery issues in the past. Now I am making it through the day comfortably. I am at 12 hours and 45 minutes and have 40% battery left. That is with wifi on all day. I am not using any task killers. All I did was calibrate the battery. Here is the link I used and it works great. DO NOT DO THE VARIATION. IT DIDN'T WORK FOR ME. Do the long version.

Also those china batts go to 10 percent in about 5 hrs but last for another 5...its odd but they are my backups anyway.

Look. The real issues are simple, the display is quite large and pulls more backlight than it needs. Not only that, but the CPU pulls more power than it needs too. I turned off automatic backlight and set it to the lowest setting. I rooted my phone and use setCPU in order to scale back the processor when it's not needed.
Also, web browsing on a 3G network is much more energy consuming. It's just a fact.
As for the apps, they activate because you have widgets on your home screen. If you want to reduce the running programs, replace unneeded widgets with shortcuts. The less programs running, the less power needed for RAM and CPU function.
What do I get in return for all of my modifications? I can use my phone for about 2 days without having to charge.
I can easily go 48 hours on my extended battery with the right settings... YEs this is with 3G on all of the time.
SetCPU is underclocking or "ON DEMAND", I have deleted most apps that come with the phone that one would never use, backlight is on low usually...
If you are sure that you have all of these settings set and still aren't seeing improvement, go to verizon and have them replace your batt.....
I can go 48 hours on the extended battery and I'm not using SetCPU and I typically leave the screen on auto brightness (though I guess I occasionally turn it down).
Yesterday's usage:
Unplugged the phone around 7:30am. Read emails for about 20 minutes in the morning, checked the weather. Listened to some music on my bluetooth headphones on the way to work, maybe 30 minutes. Started up Appbrain on the phone and downloaded/installed the apps over 3G. At lunch, I listened to more music on the way home, browsed the internet for maybe another 30 minutes while I ate, and listened to music on the way back (all bluetooth).
Showed a few coworkers some of my apps, so another 20 minutes or so with the screen on. Occasional email/text throughout the rest of the day.
At home, I sporadically pick up the phone and browse the internet/read emails/send texts. Easily a solid hour+ of browsing. Played a couple games and downloaded a couple more apps.
When I went to bed and plugged the phone in, around 11pm, my battery was at 50%.
More information about my phone:
- The only radio I toggle on and off is Wifi. Everything else stays on all the time. Wifi goes on when I get home.
- Widgets that update themselves are: a calendar widget, a Google Tasks widget, a sports score widget and a weather widget. All widgets with configurable timers are set to update in 30 minute intervals.
- I have ATK installed but only to let me manually kill processes, it has no auto killing intervals set.
- I am running Launcher Pro Plus. Before I installed LPP, I cleared off my entire Blur desktop - there is nothing on it.
- I am rooted and have removed most of the common bloatware - nothing crazy, just the things like CityID, Amazon apps, Blockbuster, etc.
Hope that information helps someone.
Speaking of extended battery and long life, I just got 34 hours out of mine and it was only down to 30%.
I'm using Juice Defender, toggling data for 2m every 15m AND completely shutting off data when I sleep, 1a-7a.
I don't have a lot of background updating apps either, that seems to be a big thing. After figuring out what works and what doesn't regarding battery life, I can use my phone as I please and not worry about batt life.
This thread is crazy my battery last all day and im on the internet atleast 4 hours a day and receive and make multiple phone calls, and text and stuff [email protected] 12.5 hours with 60% of battery left. I did condition the battery when i first got the phone i let it fully discharge 5 times

he said "****"....lol....
Bought the 1750mah extended battery. First 6 days the battery didn't last that long but the instructions did say do 8 full charges which last about 7-8 hours. I did that and over the weekend I saw awesome battery life.
Unplugged at 8am. At 10 pm I was at 40% life. That was with some light web browsing, book reading.
One thing that makes a HUGE difference. Are you in a constant 3g area? If your phone drops to 2g/1g and it can't find a signal, it will burn through your battery like crazy.
My work building is a verizon void and I get virtually no signal. I get in at 7am. By the time I leave at 4 pm, I'm down to 15% battery. I do not use a task killer. I keep my screens to a minimum. The only thing that updates are facebook posts and beautiful widget which updates every 3 hours. I use the smart battery profile.
Don't you a task killer they kill your battery faster. This is not a windows phone, its based off of linix. applications don't stay running in the background, they hibernate so there not using a lot of resources. when you kill them there just going to restart all at the same time, which slows your phone down, and kills your battery. I was getting about 11 hours on one charge using a task killer, now using it more im getting at-least 14-15 hours. plus if you have your task killer set to high it will randomly reboot your phone, even when your using it....
I dropped my task killer and my battery life is now better. I've had my X off the charger for 6 hours and only recently got to 80%.
My battery life is amazing. I left for work around 6 am yesterday with 100%. Through out the day I talk for about 2 hours, used the internet for about 3 hours straight, listed to music for 1 hour, pandora for 1 hour, and navigation for almost an hour. My battery was at 20% at 11 pm.

I have noticed a huge improvement in battery after installing leaked froyo. No task killer here but I do have watchdog installed. Haven't had it activate yet though. No widgets on blur screens and running launcherpro. Love this phone with froyo. Would have returned it otherwise.

I get 38 hrs out of my oem and 48 hrs out of my extended battery. I do have Tranquilty rom on the phone with no blur at all.I keep my sync off and just manually sync for my emails and i have no widgets besides the wheather genie set to refresh every 6 hrs.Im on the cell alot too.So i am very pleased with my battery life .

those with 30-40 hrs on one charge...

How do ya do it?
at most ive gotten bout 20
MINIMAL use (I.e. no browser).
Yes, anyone getting that much battery is running minimal services with < 10% wake time.
I usually get about 14 hours.
I keep my brightness on auto,
surf the web randomly,
I don't turn off auto-sync,
I watch videos, stream Pandora to my car stereo over Bluetooth,
sync 2 email accounts,
send and receive about 20 texts a day,
my facebook and twitter widgets sync once an hour and sometimes I manually sync them in between,
my Tech-Buzz widget syncs once an hour,
Beautiful Widgets syncs once an hour,
I use whatever wallpaper I feel like using on any particular day(some people think black saves power),
On some days I use Navigation and that knocks my usage back by an hour or two if I don't plug it into the car charger while using it.
I refuse to cripple my phones capabilities, or sit it down all day just so I can say I get 30 hours of battery time. If I need more than 12-18 hours, I have 3 spare batteries ready to go.
Disclaimer: DI8 has really reduced my battery life, however I still can get 2 days if I stretch it, and am *always* at around 70% at the end of a normal day. On my last charge before DI8 I was still at around 50% after 36 hours, with normal use.
What I do:
* Wi-fi always on, never sleep
* 4G off unless I know I'm in a 4G area, then on (it stays off anyway if I've got wi-fi)
* GPS off
* DRM and all other non-essential services off
* Screen brightness 1 or 2 ticks above minimum
* Kill only apps that I know are hogs (Google Nav, for example), leave all others alone to do what they want, use ATK as little as possible
* Airplane mode workaround for TWS
I also just don't use a lot of apps that I know are going to potentially prevent the phone from sleeping or otherwise hog up the battery if they happen to start up in the background randomly. I just don't have apps like that. Some people install all sorts of weird crap on their phones that does god knows what, I generally will only install stuff where I know exactly what it does. I also don't run a lot of widgets that check stuff in the background, although I do run Twitter and Facebook.
I am sure I don't use my phone as much as some people here, but it's wrong to assume people who get good battery life just don't use their phones. I make no real attempt at not using my phone; I use it whenever I want. That includes making calls, browsing the web (with one of three browsers), sending text messages or writing emails, using navigation in my car, and playing games.
Of all the things I do with my phone, the only thing I've noticed really super-killing my battery is GPS and navigation. That burns the battery at a rate of about 20% per half hour, which is about as long as I normally use it. But even if I use the GPS for an hour in a day, I can still get about 24 hours out of the battery if I need to.
I'm convinced wi-fi still really helps, and I'm set up so that *most* of the time I have wi-fi. I have wi-fi at home, at work, and actually on most of my route to and from work (my cable company has free wi-fi if you're a cable subscriber). I don't know how good my battery life would be if I didn't have that.
I use to get 20-25 hours easy, now I'm lucky to get maybe 8-10

Same here. Using stock DI18, rooted, mixup kernel with ondemand setcpu and juice defender (it was 5 hours b4 juice dfender installed.
Turned off the DRM service, automatic brightness. That's it. Stock everything else!
I've got GV and talk always on.
I"m a light user; sent 50+ text messages, occasionally check my email, and push email every hour.
At 40% battery life I have 2 days of battery life.
In the background I have
5 essential stock services running
digital clock wdiget
voicemail
email app
switchpro widget
My running time is 5.5% (lol), with display on 2 hours (auto-brightness), 3G on 10 hours, wifi on for the remaining time (Wi-fi policy never sleep), and TWS 0% (airplane mode trick).
Also, if you run wifi make sure you set the sleep policy to never. I'm using the DI18 update and when I turned my phone on I saw the 3G icon in the notification bar when there should be the wifi icon. Setting the wifi sleep policy to never will stop the phone from using 3G when the screen is off. NOT fixed in the DI18 update.
Attached my wallpaper lol
what exactly does wifi never sleep do to save battery ? also I seen it mentioned on a dif site, set it up that way and when the phone went off it appeared the wifi did also .. idk need a lil insight on that whole setting

Normally, wi-fi uses a lot less battery life than 3G, so sometimes you want to use wi-fi and not 3G.
You set wi-fi sleep policy to "never," so that when you have wi-fi turned on and the phone goes to sleep, it won't turn off the wi-fi and turn on 3G. So the phone only uses wi-fi and "never" switches to 3G.
You have to manually change this in the advanced settings.
I don't know if it's something I downloaded which is eating my battery. I guess I'll try to do a hard reset, if that doesn't solve it, time to root
I can't get more than 8 hours on this..any suggestions to increase it?
I never get to 10 hours but I use my phone constantly. I on average use two batteries a day. I believe I should get the most out of my phone, I am paying the monthly fee, why restrict myself cause my phone will have a dead battery, I always carry a spare.

Same here, I got 2 batteries off of ebay so I use the hell out of my phone. Brightness is on max to show off that screen, stereo bluetooth and pandora,4g is always on, live wallpapers and browse internet and play games a lot (angry birds mostly) . Battery lasts me 7 to 8 hrs which is amazing based on how much I use it. If u are doing normal use and getting 8 hrs then something is wrong, ur maybe not in 4g and 4g is ona nd ur wasting batt looking for signal oor something else. Maybe u have a service running in the background. I removed media hub and drm bc I heard they run a lot, but I never did a proper b4 and after comparison so not sure if it actually does help. I'm using noobs andromeda rom and d18 update.

Id be SO happy if I could even get 6 hours off one charge.
I'm lucky to get more than 3hours these days from 100 to 15%. :\
I did have a lot of widgets, but I removed a majority of them. I NEVER have wifi, 4G, GPS or sync on. My brightness is always set to 0%.
I guess I just use the phone too much! I don't mind because I usually am able to get near a wall outlet to charge my phone in the middle of the day.
But I'm worried about tomorrow, where I'm leaving at 8am and not getting back till 6pm with NO ACCESS to any wall outlets. I'm pretty sure I'm not gonna make it. Lol.
posted from a EPIC4G.
I'm convinced that with regular use you are gonna get 8-10 hrs on a full charge. Hell by 8 hrs you are going need to start charging unless you want to wait until the phone dies so you can claim x amount of hours.
There is no point in turning off everything on your phone and barely using it to say it lasts 20 hrs. Get a charger for work, home and your car. It is what it is.
I wake up at 6am, charge by 2 pm when battery is around 30%.
the problem with this phone bottom line is that 3g is eating the battery life. I set wifi to always on and I'm always on wifi in the house. I can get 12-14 hours sitting in my house. whoopie doo. Thats not hte point of the phone, the point of the phone is to have mobile service, not wifi service. anyone that is getting 30 hours out of the phone is using wifi. So thats not even a fair comparison. I love the phone, but this is just stupid, I shouldn't have to carry a spare battery with me if I go to the daytona 500 from 9am to 9pm.

Yeah 3G does eat more battery life than wi-fi but that doesn't mean you can't have great battery life with 3G on all the time. I can get 1-2 days with 3G on and with light use, but that's in part because I get a good 3G signal.
I probably emphasized too much on wi-fi but the point I'm trying to make is try to avoid using a weak connection. Generally, I use wi-fi/3g/4G in my home but inside most buildings they'll most likely have weak 3G and 4G connections, so I use the wi-fi network inside the building.
You said you could get 12-14 hours with wi-fi and not touching the phone? I'm not trying to be rude but that seems really low. If mines idle on wi-fi in my home it lasts days. With 14 hours idling, that means the battery life drops 7% every hour. Idling on wi-fi I think it should only drop 1-3% per hour.
Mind if you go to settings -> applications -> running services and post what you have?
i get twenty four hours on average a full day so to speak wake up it says fully charged i take it off check twitter and facebook leave the house and dont touch it until i am at school bored in class lol and then it says 95 after a full day of class it usually says 66 thats after 9 hours i go home play with it download apps etc make several calls and i text alot all day by the way and then i go to work and it says 50 or about 48 usually i use it all night off and on til i get home at seven my wife kills the battery and puts it on the charger while i sleep usually about 9

My Battery Research

hi i make some battery "meters" to compare with others and see if we have a bad battery or something its draining our battery. after several test freezing apps, motoblur services and so on i get some interesting stuff like freezing sometimes motoblur service will not help on battery in fact could cause some FC, and not sure if some apps are "calling" the freezing services that make drain faster.
i make a "chart" using gingerblur with apps, fresh sbf test, sbf with apps and so on.
i was using live wallpapers and without LWP, i noticed an maybe "obvious" if you arent in home screen LWP will not drain your battery. maybe only when you wake and stay too much in homescreen, perhaps its not to much IMO yes you can save Battery using a normal wallpaper i can say 5% max.
in my test i use NO DATA, since data will drain a lot the battery and its kind "unestable" to check because bad signal data transfer and so on, i will research more later, in all my test i leave the screen doing nothing i didint execute any process and FULL BRIGHT, and i use Battery Monitor widget to chech 1% by 1%
Using GingerBlur 2.5 in .57 version and all my apps drops from 99% to 63% ( 36%) in 2 hours using LWP in homescreen (secret LWP from SGSII)
After a fresh sbf .83 no apps installed,NO LWP after 1 hr drop from 99% to 88%, after 1:30 from 99% to 81% then i start using the phone and after 2 hr drops to 76%
then i install all my apps,using LWP drop from 99% to 70% then 2 hours later and one phone call drop to 61%
i use this .83 with all my apps 13 min phone call and 2 hours playing a movie in through my tv and drops 30%
and last using a LWP but i was in settings screen for 2 hours and i drop from 99% to 75% again using FULL Bright in all cases
(in airplane mode i get for 9 hour just 6% decrement using setCpu screen off 425)
i will compare this with my 2200mah anida battery (when arrive ¬¬ )
so im wondering who else can try "compare" this results so we can check averages and see if we have a good battery and then a rogue app.
And last i found 1 app that make me drain pretty fast
Enhanced Email (it drops in airplane mode like 7 hours like 16%)
lighflow seems drain a little no to much
My battery drains like 1% per minute on voice calls. I don't know how Moto thinks it gets 300 mins of 3g talk.
I hard reset last night and I'm getting ~3% per hour drain, which is typical for me. Screen time kills this thing no matter what brightness level I have it set at.
Here's my setup:
Blur doing FB and Twitter sync
Gmail set to push
Corporate Sync email, calendar, contacts set to push (setting this to 15 min or 30 min makes no difference in my experiance)
Docs and Voice apps, but not auto-syncing
Astrid tasks syncing with Google
A bunch of other apps that don't sync and aren't running by default (I just installed them, haven't run them yet)
I did a factory reset because something was trashing my battery usage. I burned through a full charge in 6-7 hours yesterday and my phone was quite warm.

yea seems the atrix get pretty warm a lot, in my "heavy" usage playing or watching a video can get 40+ degrees.
i get 1% per hour with no data and like 4% with data.
i was reading heavy usage and get like 24 hrs and i say no way my battery sucks lol.
i usually get like 12-14 hour with medium usage all day data on (maybe 1 or 2 off) posting on fb some browsing msn and like 4 hours playing music
i have 10% bright its enought for me. at least the atrix let me last a little more than my nexus one battery isnt amazing FOR ME perhaps isnt bad at all with "heavy" usage i guess i will get like 9 hours or little less

I wasn't using it at all. I had just power-cycled it so nothing was running (games/movies/etc.).

Lol. I came from Milestone and I am finding Atrix cold .
My Milestone in hardcore use was easily reaching 50 celsius degrees .
My atrix while I am in hard use usually stays in 42 degrees too.
Guys i get a full day out of this phone without even trying etheir you guys are not flashing the phone properly or your phones are corrupted this phone has better battery life than my iphone 4 did
I get at least 2 days. Now that I am not playing with it constantly, I normally get 3 days (and 2 inactive nights) to about 20-30%.
Not rooted.
Do fairly regular email, fb, maps, /. , etc.
No movies
Virtually all data is via WiFi
BUT
It is not my primary computer. I program days and do most of my work on a real computer. Tonight in my chair with a glass of wine, I am using an Eee netbook -- a real keyboard is dramatically faster for me.
And I have developed the following important habit: I always put it to sleep with the slanted key at the top whenever I am done, so my screen time is fairly low. I think this helps a lot.
I expected battery life to be a problem before I bought it and that's why I like the back cover -- easy to change the battery. However, this has even better battery life than my last Blackberry and I thought that was excellent. I won't be buying another battery until I have a year or so on this one.
I believe the essence of all of these power conversations is that if you use it as your primary computer, you will use up the battery fast. If you use it primarily as a phone and as a portable secondary computer, the battery is excellent.

FYI
I'm currently running 1.5.7 & a couple of days ago i froze updater 2.2.1 because i was sick of getting reminders to update (using gladiatrix). Since then (although it only just clicked) my battery drain has been horrid (10% per hour in standby), after thawing updater 2.2.1, my battery drain has gone back to normal (1% every 2 hours in standby)
Mmmmm I will freeze as well to se improvements perhaps there is no updates atm and maybe will not get better

Nexus 4: Best ways to save battery?

Hey guys, so ive had my nexus 4 for around 4 months now? might be more and the battery is just terrible, obviously we already know this as ive seen so many people post about it and such
my question is this, what do you guys use to save battery? Im currently on XYLON ROM with Perf-enhanced-Stock-422 kernel which isnt bad, theres nothing wrong with it in fact but i literally only get around 2 hours screen on time, terrible i know
ive heard people say flash android 4.2.2 and then flash a custom rom, apparently it helps or something? not fact but ive seen a few people solve it with this issue
What kind of roms and kernels are you guys using? And what governor?
Cheers guys, Jack
I've seen most people running Franco kernel with either cyanogen mod 10.1, PAC or paranoid android. You'll probably get a similar battery life with all of them, and probably the best your going to get.
Check your wake locks, use juice defender, check you're not dropping in and out of signal (hammers battery), turn of location settings...
Sent from my GT-N7000 using xda premium
AKOP or CM with franco give me hours (4+) of calling or 1.5 days of moderate use.
I also have notification widgets on so I can quickly switch BT/WIFI/Brightness AND I make use of nfc tags so when I'm home wifi is auto turned on and when in the car it turns off.
From my experience, these battery saving apps such as juice defender are not good, you shouldn't use them.
About the battery life, there are tons of recommendations... stop syncing, turn brightness to as low as possible, turn off 3G when you don't need it...
Dont use your phone..
Seriously now, the battery is not bad at all, and in battery usage cases you need to state your usage of the phone (games, mail, 3g on most of the time? widgets? surfing and screen on time)
Without those parameters none can determine if you have wakelocks problem / some app is draining your battery or eventually maybe it's only psychological problem
Take in mind even on auto brightness, if you are playing heavy games dont expect to last a day or so..
Tricepz is on the money!
Need to analyze Your usage!
Most importantly you need to understand that this is not a primary game console or music player.
Things that drain battery fast!
1) Live Wallpaper
2) Games
3) Phone calls
4) Equalizers
5) Apps
Best to monitor your usage!
Personally I use the phone as follows for 16 to 22 hrs of usage.
Bus
1) 4 hrs of music with quality headphones that have noise canceling tech. Abel Planet 200b with built in amplifier.
2) 3 phone calls a day!
3) No games ! Have a tablet for that
4) Minimal reader for new feeds only updates once a day.
5) Music app either Apollo or NexMusic great music players without equalizer. simple controls.
On an average day headed to work paying bills I see 10 to 12 hrs easy.
Busy day on my phone 8 to 10 hrs.
Turn off services you don't need or use.
WIFI - Turn it off when you leave your house and when you don't need it. Leaving it on will drain power as it will continue to scan for a connection.
GPS - Turn off your GPS if you don't need.
Sync - Sync when you need to. Turn it off and access it manually.
Bluetooth - Turn it off when you don't need it
Location services - Go to the Settings menu and head over to Location access and switch "Access to my location" to off.
Backup services - Head over "Backup & Reset" and uncheck "Back up my data".
Screen brightness - The lower the brightness, the more power you'll save.
Apps - Applications like facebook and Google Maps will remain online as it runs in the background. As a result it will drain your battery. It can prevent your phone from entering deep-sleep to preserve power.
Signal - Connection is very important. If you're in a area where service is low to poor, your phone will draw more power to stay connected to the nearest cell antenna/tower. It's best to turn off on connections if you're in a no service area. Simply put the phone in "Airplane mode".
Usage - Battery life is dependent to whatever tasks you are performing on your phone. If you play games daily for a long period of time, then you should expect the battery to decrease dramatically. Conversely, if you just email, text, browse the web, make calls, little to no games then your battery life of the phone should last for quite a long time.
Useful apps
Greenify - This application allows you to hibernate apps from starting up like facebook, Google Maps and many more annoying apps that run in the background when they shouldn't be running. https://play.google.com/store/apps/...GwsMSwxLDMsImNvbS5vYXNpc2ZlbmcuZ3JlZW5pZnkiXQ..
Wakelock Detector - This wonderful app identifies apps that running during your usage and sees which one has been running the longest without your consent. You can use this with Greenify. https://play.google.com/store/apps/...EsImNvbS51enVtYXBwcy53YWtlbG9ja2RldGVjdG9yIl0.
BetteryBatteryStats - Similar to wakelock detector but offers a more in-depth look of wakelocks that active during your usage. https://play.google.com/store/apps/...wiY29tLmFza3N2ZW4uYmV0dGVyYmF0dGVyeXN0YXRzIl0.
Kernels and roms
One major reason why root is amazing. Kernels offer tweaks that are beneficial for the phone to perform smoother and offer amazing battery life. Offers more tweaks as well like gamma and undervolting. Roms can contribute a small portion of battery saving but not much.
Did I miss anything else?
Adding Maps to Greenify usually helps a lot regarding battery life, can leave GPS on for other apps when doing this and won't suck any battery.
try franco or faux and then UV and UO ` its works for me, 4+ screen time easily :fingers-crossed:
I didnt expect so many comments! ive used franko kernel and air kernel before and no change
ill try some of them apps that everyone has mentioned
again thanks guys! Jack
Just use a ROM for a while, let the battery do some cycles, and use the phone for that, as a phone, remember that we have a Quad Core here, i'm on stock rooted only, and last night i get 12h20m37s with 4h48m SOT with about 7% left, so that's pretty good. And i really use my phone, Twitter, Flipboard, G+, Wifi on all the way, Sync on.

I guess you are one of the lucky ones! i hardly use my phone for gaming, i have 2 games on there and i use facebook twitter tumblr etc 3G is only on when i leave the house but other then its on wifi
just got to 46% with 1hr 50mins screen on time so ill probably get around 3 hours today.. i just dont think its good enough :/

Yep definitely something's not right, facebook is known to be a battery drainer, i suggest to you that open it up on the browser and uninstall the app, try it!

With 80% left I have 1hr of screen on and 10mins of call time, this is with whatever kernel the latest CM nightly is using, so yeah you could definitely get better but I have to think facebook is the contributor since I too have twitter (plume) and tumblr without the same battery drain.
greenify is a must to disable rude apps which do thing without asking, like facebook, games, etc, they connect to internet to download ads and sttuff, facebook being the worse cpu eater
i use 2g only, wify in home, disable wifi outside,
only wassap active, some opera mini browsing, pics, talk, sms, little gaming, i get 1.5 days
off course heavy gaming kills the battery, because of 3d, even 2d games drain the battery because of the screen, like angry birds
using stock 422 + franco
I like to use JuiceDefender only when the phone's battery gets really low and I want to sacrifice some functionality. It works well, but only if you allow it to keep 3G/Wifi off when the screen is off.
I use facebook so much though, ugh :/ ill give it a go and if the battery lasts longer then ill get rid of it
single biggest difference I've seen is to stay on wifi all the time as much as possible. I leave it on no matter what. Granted if you are out and about, it won't help but once you get to home/work/friends/etc, your phone will immediately connect and start saving you juice.
91% after 8 hours with light usage at work. With 3G, I normally would be approaching 60-70% by now with light usage. That 3G drain is real and should be avoided whenever possible.
Don't play games. It seems like no matter what game I play, it'll almost always lock my cpu to the max frequency until I exit. Even really simple non graphics intense games.
Well ideally you're biggest battery drainer should be the the display. If it's not then read below.
1) So for the screen the best way to go is to get a stable custom rom like xenon and tinker with the auto brightness settings. Tweak out auto brightness settings to your liking (they're generally very overbright by default) and you'll see major increases in data.
2) Screen aside your other biggest drainer is cell radio. Particularly if you're in a low signal area it will drain your battery really fast. So if your using wifi anyway be sure to turn data off and switch to 2g. That way you'll have a strong signal and 2g drains less battery anyway.
3) As some people have mentioned already. rogue apps. Social networking apps are a huge drainer in this regard. Especially facebook. You just can't have that app on your phone and get decent battery. As for other apps which draw on unnecessary background data, Greenify their a**es.
