hey pretty new on mt4g so i wanted to gauge battery life and see what other people are seeing. I'll start and lay a rubric for everything I'm seeing
Mytouch4g
Rom cynogenmod 6.1.2RC2
Grankin 2.6.32.27 oc'd to 1.8ghz. Kernel
Have set CPU set for 245mhz on screen off/On demand. And normal is 245 to 1.8ghz on demand ad well. ( Not sure what's good profiling and stuff
Have Facebook and ebuddy and everything is off cept for data. No email only push Gmail
Hitting about 1% every 20 min and when i do browsing for like 20-30 min i lose like 10-15%

Nice..
Mine can only hold for about 15 hours, lite web browsing, barely phone calls and texts..
I got about 16 hours yesterday. Using CM7. Brightness all the way up. Everything on except wifi. Browsing about 2 hours. About 5 phone calls, 15 mins or more. Used google maps. Did about 20 text msgs. I think that's all I did. Loving the battery life on CM7.
I get like 2 days use out of my phone without charging it. I've always tried to figure out why my battery life is always so much better than my gfs and I think I might have figured it out....I'm always on wifi.
The two places I am the majority of the day (work and home) I am constantly connected to wifi so it keeps my radio from scanning for a bettery data signal so my battery lasts a lot longer.
I have:
Iced Glacier v.1.1.6
Gorilla OC 1.6ghz beta v05 (but runs at 1.7ghz?)
SetCPU set at 1.7ghz ondemand and 245mhz screen off powersave
I get around 16 hours from a full charge, but Im always on the phone and playing with it but I have noticed that my battery does last longer on wifi
after tinkering around with it its working out better.
using
CM7nightlies#9
CM kernel
no setcpu
i get around 20 to almost 24 hours of usage. but most of the time i'm charging or partial charge cause i stream music like a mad man ahha.
stock i can get almost 24 hrs on a full charge im also using screen filter app(awesome app to use) im on pocket empires a lot too
Is it just me or does 100% last longer when fully charged? Has anyone also observed this? ATM I have 93% at 20hour mCPU scaled at 768mhz and around 15-16H moderate use with scale at 1.6GHz on max load.
I bought the Mytouch 4g on black Friday and found problems with the battery life in the first week. 5 Hours maximum without even using it. The camera worked randomly. I exchanged the phone for another one and all my problems were solved. I use the phone for gaming mostly and that drains the battery obviously .
I purchsed the powerskin case from the T-mobile store and I couldn't be more satisfied. I can use my phone for 6-7 hours straight playing games and browsing the web and it still has a full battery with a bar left on the power skin. It may be a little bulky but it brings be back to the good ol days when phones were bricks and adds that extra padding that I feel is necessary for protection. The price tag on the powerskin was $70 at the store but when it was scanned it came up as $40.00.
I highly suggest this product for those with fear of their phone dying unexpectedly.

Just because of root your battery is that great? My brightness is off all day and my Data is off and my battery MIGHT last me till like 10:00 PM..
This is probably a silly question, and after quite a while searching I haven't found any real answer, but here goes:
Going from original out-of-the-box to rooted RoyalGinger 2.1, the battery use by my Display has gone WAY down. Like from always being #1 to usually being well below Cell Standy, Phone Idle, Wi-Fi, etc. And it's definitely not that I'm using the Display less.
Has anyone else seen this? Does it have something to do with how RoyalGinger, Gingerbread, etc. calculate battery usage? Is it normal?

yes its normal. you came from stock MySense UI(stock Glacier), and Sense builds are known to be battery whores because they look awesome, have loads of interactive widgets, and lots of bloatware as well. going to an AOSP build(CM7, RG) the ROM is very lightweight and contains little to no bloatware and still as fast, maybe even faster. just look at the size of the files...Sense=300+MB, AOSP=80-110MB. plain and simple, all of the bloat consumes more power on your display

Thanks for the prompt reply. I guess I didn't expect the Sense bloat to be reflected in the display usage. Does "Display" include the touch interface as well? If so, I guess I can see why Sense would show up as display.
Display counts more than just the power used by the LED backlighting.
I plugged my phone in yesterday at 14 hours of uptime with 45% battery remaining, after a day of fairly heavy use. Close to three hours of music listening, two hours of screen-on time and 3G/wifi web browsing, forty minutes of voice calls and a few SMS.
Using CM7 nightly #143 and insanity v3 kernel, 122/1017 clocks with smartass governor. I'm sure if I switched from smartass to conservative my battery life would increase a bit, but I like the smoothness that smartass gives me, and even on a day of brutally heavy use, I'll still come home with at least a quarter charge left.
Here's mine. Don't post attention to the time, I rebooted a couple times, it's probably been about five hours on battery. I don't do too many games per se, but I do browse xda and facebook a lot

here's mine (i'm too new to post links):
15h 12m 37s on battery
Android System 44%
Cell standby 22%
Phone idle 18%
Voice calls 8%
Wi-Fi 6%
Display 5%
as you can see (er, read), the display is really low. not sure what's up with system (maybe scanning the sdcard?), usually it's just standby and idle at the top. this is on RG2.1 with the display on auto brightness with defaults.
so this really is normal?

yep, that looks about normal for AOSP builds
Well I won't complain. Like I mentioned, I was really surprised at the low battery consumption of the display. Didn't expect that much difference just by changing ROMs. Wish I would've rooted a long time ago.
Thanks again for humoring me and my silly questions.

i don't know if I received a "dud" unit in the sense, but i have noticed INCREDIBLE battery life on my Nexus S with moderate use. the first day i had it (2 days ago), I charged to 100% and then started using it. I would say I did about an hour of browsing, an hour of talking, an hour or so of texting, maybe 10 mins of GPS use, and an hour of unlocking, rooting, etc. also just left the phone unplugged from charger overnight. on the first charge, there was a point where i was at 1 day 12 hours and 16 mins on battery and still had about 40% left or so. I even have a pic of the battery usage page I will post. *it should be noted that i turned off wifi, gps, etc when i was not using it. and did not use a live wallpaper. *edit: i also had background sync turned on the entire time. syncing gmail, contacts, calendar, etc.

That's over 2.5h "display on"-time and still 40% left, sounds quiet impressive. There's something wrong with your phone, in a good way.
If your numbers aren't accurate though, it's "normal". Idle use of 1% and less per hour w/o widgets and background active apps is nothing special.
it may also be related to you being on AT&T. i've read in various forms where people say that AT&T's mhzs (don't know the technical term) use less power than T-Mobile and WAY LESS than Sprint, which results in better battery life (the whole CDMA vs GSM thing).
The Sprint CDMA ones seem to have the most battery issues.

I'm actually seeing an increase in battery life with GRJ90....
My phone without mobile data on lasts about 20 hours...with mobile data enabled, but not necessarily active because i am usually on WiFi the battery life is reduced to maybe 5 hours...pretty bad...mobile here is Edge
Could it have anything to do with being in a bulding with thick walls? maybe the phone is using more power transmitting just trying to figure out where the cell is?

While it is true that bad signal harms battery life, 5h is ridicously low. Those 5h, how long is the display active in that period?
Check the battery status and see what is draining your battery so fast.
Try to change the WIFI rules from "turn off wifi when display is off" to "never turn off wifi" (you can still disable wifi the normal way, it just won't time out if there's a valid connection available), you can also set your phone to "2g only", if - as you said - your area has edge only anyways to further safe battery.

well its not a cdma vs. gsm thing, if sprint where able to purchase those frequencies they would have and it would have been different.
Much the same with tmobile them being so late to the game those are the best freq. they could obtain.
much like how sprint/clear's wimax sucks really due to bands it had to run on.
during the 5 hours, display is on for very little time....wifi is not a problem..when the display is off i still get email notifications and all that...i dont turn wifi off when i go out to the street and its constantly searching and i still get like 20 hours...but with 2g on, battery goes fast. I am not worried YET though, as my time at this 2G only location is about to end soon, then i will test 3G. I will spend some time in the US and plan to get simple mobile there...i belive that will be 3G with the Nexus S.
I do more tests once I get there...here I cancelled the 2G data this week since it drained the battery and i barely got 20kbits downloads (literally useless).

Out of curiosity, how much time were you getting before and after the update? I sold my two Nexus phones because I was getting maybe 5 hours tops with average (not heavy) usage!
I am hesitant to try the Nexus again, unless everyone says the update made the battery life much better for the CDMA version.

This is around what I'm getting (without a LOT of Wifi usage, maybe an hour 1 tops.....the rest is on 3G). The way I like to test my battery is to see how far I can go WITHOUT Wifi because of course it will last forever with Wifi on (should anyway). I can average like 15 hrs a day, with around 3.5 hours of display time on (really depends on what I was using it for) after the update....
Along with that, the new Gmail update will most definitely increase the battery life even MORE now because I keep EVERYTHING on, including:
- GPS AND 3G location services (use to turn 3G location services off, but the battery has been so nice on the Nexus I never found the need to anymore)
- Auto-sync turned on for Google Account services (Gmail, back-up, etc.) and Exchange account
- Exchange Push account (syncs 3 days worth of stuff)
- Auto brightness for my display (I drive 2 hours to work and 2 hours back, and on the way home the sun is constantly on the screen so it has to auto adjust for the brightest setting for however long I use it driving home from work).
I don't have many accounts syncing or anything (not into Facebook, although I have one) so that may be why. But prior to the update, my 3G signal was weaker so my battery would die a little faster (although I've ALWAYS been able to make it through a day of work with my Nexus). For me, the battery life has always been the best of any smartphone I've used, but after the update it seems a little bit better; not DRAMATICALLY better, just a little better (still can't touch the iPhone 4 on-call phone I had for work for a week......didn't have to charge that thing but one time during that week )
Again, this is with the Nexus S 4G
I meant 5 hours when it is sitting idle most of that time. Maybe 2-3 hours of actual usage.
I have going long as 15 hours with normal usage.

You seem not to be on Sprint (cdma) so this particular battery issue is not related to you...
I'm really amazed to be hearing about all of these phones with such terrible battery life. I have a Nexus S 4G & my battery gets me through half the day now this could be due to the 1750mah battery I'm using & then I'll switch to the stock 1500mah to finish out the day. I consider myself to be a fairly heavy user because I'm always on it sending text, emails, web surfing, phone calls, utilizing it as a hotspot & the only thing I've noticed that really puts a drain on my battery is downloading massive amounts of data, streaming data & watching movies on Netflix. I even use it to game online with my PlayStation 3 because I'm in an area where there is no internet & signal strength is all but none. I guess I too have an anomaly but nothing like a day & a half I wish. If there is anyway to extend battery life any further I would love to know.

I get amazing battery life on my Nexus S 4g. I owned the Epic and the Evo before the Nexus S and I gave up on those because of the battery life. I'm usually at over 30% at the end of the day. I do have the latest stable build of netarchy installed. I undervolted using setcpu and have 1 profile. Underclock to 200mhz when the screen is off. I sync my Gmail as well.

Look at all these OMGZ BATTERY LASTED FIVE DAYZ AWESOME BAHHHH! I've noticed one common thing between them all, well 90% of them at least, the owners don't use their phones. You see these long battery life's but very short on screen time and very long intervals in between on screen times. Its common sense that you'll get great battery life if you let your phone sit hours on end just idling.
For the people who actually use their phone like texting, phone calls, surf various sites, and play games, having great battery life like all these people say is a dream. I want to get an idea on what real world use on your phone gets you.
Here's some screenshots of today's battery cycle, which is about average everyday for me. I've sent and received in the neighborhood of 250+ texts, surfed various sites, trolled xda, played a game for a while, and read my news.
So let's see what my life compares to all the other power users like myself vs the people who let their phone idle in the corner for three days and say they got amazing life.

That's badass!! Though I don't use my phone much during the day at work. I check Tweetdeck for facebook and twitter timelines, XDA app, gmail, listen to music at times, read news through Pulse and Browser. Here's my battery stats for that one day that I wanted to see how my battery would hold out with deep idle on. Did not plug it in to charge entire day (I normally charge it while working).
This was on AOKP M3, Matr1x 16.0 cfs 200/1000. WiFi on in the morning when I woke up and checked some stuffs before heading to work. No WiFi at work entire day, then WiFi on again when I got home as shown in the screenshots.
Oh geez.....yawn

Not everyone uses their phones the same way you do, while I do agree that people who just let their phone idle just for the purpose of getting amazing screenshots doesn't accurately portray real world battery usage, it still doesn't mean that we all use our phones the same way you do, for example I have school during the day, I can't be using it constantly so of course I'll be getting better battery life than "power users" but then again this is MY REAL LIFE USAGE so I'm not just letting it idle on purpose, so please don't put everyone that gets good battery life on the "OH MYY GAWDZZ" boat. Also I do actually use my phone, I get everything I need to be done on my phone while consistently getting 20+ hours with 4-1/2 hours screen on time.

Well thank you for expressing your feelings about categorizing people. I said that because well that's what most people do on here, truth. The whole point of this is to see what people are getting that use their phones, power users or not. I just want to get a good look and filter out the people who sit on their phones, turn data off and all that. You're completely right that no one else might use their phone as much as I do but I'd rather get a good look at actual use rather than like you said, looking to get that amazing screenshot.

I understand what you were trying to get at. Its just not everyone is using their phone like you do so REAL LIFE usage will vary greatly depending on the user.
to many variables these threads are getting redundant...

But this is my real life usage, I'm just not into heavy gaming Would've had around 5% more if I didn't get a random reboot at around 75% mark.
Activities include: email & whatsapp sync, around 10 mins phonecalls & 20 texts, reading ebook, browsing web & market, playing light game.
What makes a difference is good signal reception (all green/not using 3G unless there's no wifi and I need to download a file) and constant access to wifi (working from home, didn't need to go anywhere the last two days). Setting screen brightness on lowest unless I really need to turn it up helps too.
On heavier days when I'm out and about, using GPS navigation and mobile data, making more phonecalls & texts, taking pics, I typically get about half of that (20-24 hours).

well there's the thing about letting your phone sit forever, but also wifi. a lot of us sync a lot of stuff, so even when we sleep the phone will lose a clear 10% overnight. That's fine and all, but when you're on wifi, the stress on the phone is a lot less simply because 3G data takes a LOT more power....

Hey guys, had my Nexus 4 for about a week, the glass on both sides is still like butter and delicious. Battery life is another issue though, I can't even get through a whole day of regular use without charging. Is anyone else in the same boat as me?

While my battery life is nothing amazing (3hrs of screen time/12 hours full usage) it's not nearly as bad as yours. This is strange. I thought tests indicated that the average battery life was 4 and a half hours of screen on time? I'd love to know if there is a possible battery problem that is causing fluctuation in battery life between phones.

Yes, I seem to be. Usually good with battery management too. Very similar statistics for me. What is your brightness set at?
Sent from my Nexus 4 using xda app-developers app
automatic brightness, this is discharging from an overnight charge, so 100%
Automatic brightness tells people nothing.
Depending on your environment it can range from almost the lowest brightness setting to full if you're out in sunlight
I'm sure the terrible signal isn't helping much. Try switching to 2g when you aren't browsing etc.

My nexus on auto doesn't go as bright as the highest brightness setting. It's about half way or default.
Switching to 2G when I'm at home with wifi coverage helped some. The improvement wasn't dramatic, but it was noticeable.
Are there any apps that will turn off mobile data after a certain period (say 15 minutes?) to save battery life? That is the only thing that I can figure is killing my phone so much more quickly. I have unlimited data and no wifi at home, so I leave it on at all times. My old phone, however, had a setting that would turn it off after the screen had been shut down for 15 minutes (and turn it on occasionally to sync).
I don't want to have to toggle my data on and off all the time to make the phone last more than 7 hours.

Juice defender will shut data off when the screen is off
Unfortunately, I don't have any tips. I have the same usage (though mine was all on HSPA, no WiFi) in a fairly bright room with auto brightness and nearly identical battery life. My Galaxy Nexus under the same usage conditions would get significantly better (3-4 hours of screen on time instead of 2).
Doesn't seem to be better :S

Hey, I am still getting similar statistics to you. I turned off Google now last night and set the brightness to just over quarter (in case it was the auto brightness that was the problem).
Still getting terrible numbers compared to others, it seems that those of us getting bad batt life have very similar numbers in terms of time off charger and screen-on time.

Turn off wifi if not in use, there is some bug with it.

Hey guys, had my Nexus 4 for about a week, the glass on both sides is still like butter and delicious. Battery life is another issue though, I can't even get through a whole day of regular use without charging. Is anyone else in the same boat as me?

I have had greatly improved speed and battery with Code fire X BR2 ( haven't tried BR4) and Matrix 2.0 kernel. Also I set my cell radio to GSM auto PRL which prevents the phone from constantly searching for 3g if signal isn't strong enough (or something like that) but helps. I also left the screen setting on auto brightness.

will future software update fix this battery issue.
6 hours is terrible
CPU uses a lot cause it is so powerful

3hrs 30min screen time.
Running 4.2.1 rooted with the Matrix 2.0 kernel and gov set to interactive. No other tweaks or anything special done to try and increase battery life. 2 mailboxes using push mail and on Wi-Fi for the better party of the day.
I would check using CPU Spy and Better Battery Stats just to make sure your phone is getting in to deep sleep, and nothing is holding the device awake.

Auto Data is much more lightweight and has less settings to get lost in than Juice Defender. You can set it to turn data off immediately or after fifteen minutes

For some reason I think the numerous stock google apps spend a lot of time phoning home. I disabled seversl of them that I don't use in the app settings (G+, Currents, Magazines). That changed seemed to help and it's easy to try.
I recently got a razr HD and i noticed my battery barely lasts a day. I had a flip phone before and it would last a week on one charge, i know i wont get the same type of battery life. I downloaded juice defender and set it to turn off my wifi/data when not in use. It has helped a bit since before that my phone would lose 2% battery an hour just in standby. I haven't downloaded any task killers, but when i'm done with my apps i go in to the settings and close them.

Two things to fix,
one, adjust your brightness to auto. The higher the brightness, the faster your battery dies, that is massive screen use.
two, poor wifi/cellular reception = ****ty battery, the phone uses more power to lock onto signal.
Dont use task killers, they do more harm than good.
I adjusted the brightness on my tbolt and I doubled battery life

Hmmmm. i wasn't very through with my post, but i have mine set on auto brightness. My wifi at home is usually 4 bars and 3 if im in the basement. I get 4 bars LTE for 95% of my day. In the main building on campus i get 1 bar if im lucky but usually its out of service so i depend on the wifi. The only thing i use my phone for is listening to music on my way to school, texting, email (but i set it to sync every hour), some light internet browsing, and calls.
Edit: Also on a sidenote is the smart actions useful? It seems like it does the same thing like juice defender.

yes, smart actions does the same thing with less battery,
UP your sync time! The more often you sync the more battery you use! I would put it on 4 hours and only sync if you need something important.
Turn of your cellular radios at school and that will help battery
Clearly your screen is consuming most of the battery. Try lowering your brightness, If you used it to text and kept the screen on for long time.. it might have consumed battery in that period. Not sure if its helpful or not .. but here are my battery stats after a normal usage day.

The 3 hours in sync shouldn't be eating up my battery though, but i guess every bit helps.
This is after taking it off the charger at 0800, I use my phone all day with limited smart actions.

Do you think its my battery? I got suckered into the futureshop warranty and they said since my battery can't be replaced if anything happens to the battery they will replace my phone for one of an equal value or greater if i pay the difference.

nah, just change the sync settings to longer and set your brightness to auto and see what happens over the next few days and report back.
I noticed the biggest difference when turning off WiFi and mobile locations.
Also 4.1.2 seemed to increase my battery life dramatically too.
I don't think setting the brightness to Auto is the best for saving battery. When in auto, the light sensor is turned on and some processing has to be done to define the brightness every time the screen is turned on. And that consumes energy.
I always keep mine at 50% and, when in very bright places, I go for 100% brightness.
Hi again, today i disabled my wifi and data manually whenever i wasn't using them and manually enabled it whenever i needed it. It worked a lot better and i left my house with 85% charge and i used my phone a little bit more than yesterday and it used up a little bit over 25%. I also played around with my juicedefender settings and hopefully it will work better. I will set my brightness to 50%. I'll post back in a few days. And is my battery working properly, because i honestly expected it to last a lot longer. Also thanks for the suggestions.
I really like 2x battery for controlling battery usage by data connections. There a light version as well. It basically turns off mobile data when the screen is off and turns it on when the screen is turned on. It can do the same for wifi as well. The light version will reconnect and sync everything every 15 minutes (or you can turn sync off). I paid for the full version and it allows you to change the sync time to longer increments. I use it mostly because I don't want to have to remember to toggle and where I work the 4G signal isn't so great.

Have the same problem! Brightness is low, internet is off, when I don't need it, still the battery is weak!
You said you had a flip phone before and the battery lasted a week, is this your first smartphone?
Smartphones have a 24 hour battery life at best, This phone has an above average battery I have had 48 hrs out of it..
other things to get in mind is the ROM you are using, I see you are on stock Ice Cream Sandwich, ICS have a good battery life, I have tried Telstra Jellybean and it was not as good, I also get excellent battery life with epinter's CM10
I am very satisfied with the battery life! I also recommend x2 battery, which seems to prolong battery life with little to no impact on the usability of the phone (at most a potential short delay on emails when not on wifi). I generally use wifi whenever possible which use much less battery than the mobile modem. Also I have disabled a few stock apps that I don't use e.g. the non-gmail (stock) email app. The phone is not rooted and using stock o2 JB rom.

Wow sick battery life, do you have the MAXX HD?
I think it is as well. I admit it may be a little "inflated" by using Wi-Fi mainly rather but impressive nevertheless. Wi-Fi or not I generally experience good battery life. I have the normal non-Maxx edition bought in Germany September last year.

Also have a look using Better Battery Stats app to see what your most battery hungry wakelocks are, especially Kernel wakelocks.
I had issue when I first got my razr as I was using it on a network that doesn't have Fast Dormancy yet the phone has fast dormancy enabled, so i had to freeze it and battery life improved a little.
But unfortunately fo me the main problem was where i live. I'm in a city, so it's not a lack of cell towers, but for some reason at home my battery usage is insane while connected to mobile data, 9%-11% an hour with no use compared to 2%-5% elsewhere around the city. (Am thinking it must be getting bounced from tower t tower trying to get a better H+ connection) As soon as I switch over to wi-fi tho (which I have set to always on,) my battery usage drops to about 0.8%-1.2% per hour in standby.
