I've had my skyrocket for about a month now, and I've had horrible horrible battery life compared to all of you guys on here. I've tried reflashing, did the whole .3e recovery/ wipe/ fresh install tutorial that Seanz posted. (Amazing rom by the way.)
Nothing seems to work. I've calibrated my battery at least 4 different times. Oh, and for Seanz, You say your rom is 2.3.5, but in my settings it says 2.3.6. My brightness is all the way down, My data, bluetooth, gps, etc are ALL OFF! Only thing I keep on is wifi, ALWAYS. I've tried leaving my phone off the charger all night and locked to see if the drain was the same, and it is, If not just a tad less drain. I'm sorry if I didn't clarify this good enough, If someone could help me out I'd be glad to explain myself better!
Does your phone maintain a strong to moderate signal (both data and talk)? This includes the strength of your WiFi connection. I've noticed one of the biggest (if not the biggest) drain on this phone and most others comes when the phone is strugling for a decent connection. If you can, try this: put your phone in "Airplane" mode for 1 charging cycle. This means your phone won't even try to get a wireless connection of any type. To be safe, make sure the "WiFi" is off as well. See how long the battery lasts compared to it not being in "Airplane" mode. If it still sucks, you might need to see which app(s) are draining your phone. If it is noticably different, a weak signal might be the problem. Good luck.

He changed it only in text for certain apps that require Android 2.3.6, even though they'd work completely fine on 2.3.5. Somewhat an easy workaround. Also took some of the features from 2.3.6 in. It's still built from 2.3.5 though.

Thiiiis is probably your big issue. If you have any apps running in the background that use data, they can keep the wifi awake, which, in turn, never lets your phone sleep. If you go to Settings>Wireless and network>Wi-fi Settings>Menu Button>Wi-Fi Sleep Policy, and set it to "When screen is off," you'll be AMAZED at how much life it can save. I've noticed drastic differences when that setting is applied. As far as without it losing around 10-15% overnight to a mere 1%.
Thanks for your replies! I'll try you guys' ideas out now. I seem to lose about 1-3 percent every 10 minutes. I'll put it in airplane mode and try it for an hour.
Thank you Fortune! was wondering how to do this, You could have just solved my problem. I'll keep you guys informed! I'm amazed at this communities helpfulness. Thank you!
No prob!
Though, next time, if you have a question, should post it in the Q&A section of this forum. People tend to get a bit pissy about seeing Q's posted in other places, haha. Just giving a heads up!
Hope those fixes fix your battery life! That wifi sleep on has been key for my 30+ hr battery lives on SkyICS.
Seemed to not help :| Since I've done this, It's gone from 22% to 17% in about 15-20 minutes. No apps running, etc.
Try downloading CPU Spy from the market place and after awhile of letting it rest (about an hour or so), open it, refresh and check to see the CPU uses the "Deep Sleep" frequency at all and to see which frequencies it spends most of its time in.
Also wouldn't hurt to check Settings>About Phone>Battery Use to see what's using most of your battery life. Display, Android System, and Android OS typically hold the top 3 spots, so if anything is up there (or at a close 4th), that app could be what's bogging it down.
I downloaded CPU Spy and it seemed to already have data for it and it says 4% in deep sleep, 65% in 38 mhz, 5% in 810 MHz, and 1% in 1026 mhz, 17% in 1728 MHz

Alright, well so far so good. Shows it's at least getting some deep sleep and able to idle in low frequencies. Can't really get TOO well of a reading until it's done some time with it idling though.
Do not set wifi policy to screen off, keep it at always. this will keep your data using wifi when connected which is way less of a drain than the 4g radio. Basically with the screen off policy your phone will still use data, it will just come from cellular instead of wifi when screen is off.
Also get this

It will tell you what is running constantly and draining your battery.

Since he has his data off, turning off the wifi with screen off will benefit him greatly. It would be stuck on otherwise. Noted:

Ohwow.... That's....... Interesting, haha. If I notice my wifi is on for extended periods of time, my battery starts draining a bit faster than normal.
Might have some app in his background either keeping the phone awake or just hogging background data, keeping the wifi constantly active.

the real issue is when i actually stop being on wifi. when my phone uses data connection, mostly LTE because its everywhere around me, the battery life becomes miserable. I left the house for about 1 hour today, you can clearly see it on the graph. I should try to cut all connectivity and just allow the phone to sync every now and then, im sure ill be able to add another half a day at least to my already 1.5 days with wifi on all the time

Yeah, data is a KILLER. For me, it's usually wifi or nothing, unless I'm trying to send or receive an MMS, or need to quickly access the Internet, but I turn it back off as soon as I'm done, and I set my network to no LTE because it's not in my area.
Just take that as a note OP, lol.

That sounds like what I have right now.
My phone is rooted and I have it unplugged since 9AM. It is now 3PM and down to 50%. This is what I did:
Bluetooth Headphone + music for about 1hr
Downloading apps + updating + reinstalling + backups + uploading for about 30 min
Texting + a few emails + fruit ninja + angry birds + GBA emulator for about 30 min
I'd save more battery if it wasn't for the data+CPU intensive activities.
Goto the verizon store and talk to the manager. Tell him to push the hybrid prl to your phone. Mine is 13006 & battery is at 80% (off charge 6am) at 3:34pm. Looks like a major fix for me and the wife's thunderbolt.

Try Battery Monitor Widget. I was surprised to see that my phone uses significantly less power while idle on 3G than connected to WiFi.

I spoke. With corporate about that, tier 2. They said prl updates automatically on boot and the is no way to push a specific version. They also said prl is for voice roaming in non VZW covered areas and isn't related to the 4g radio, as only VZW towers support LTE.

What does your usage look like? If I just open up my phone for emails and text (very light usage), I lose about 10% every 4 hours or so. Also I think you can edit your tower preferences by dialing " ##778# " . I'm not sure if it's the same but sounds quite similar.

What are tower preferences exactly, and what would they do to help battery life?
The reps on the phone are full of it! I have been on the new prl and it doesn't change when I reboot or bsttery pull. It has something to do with wether or not you are in an area that use to be alltel. If u goto the store they should know what ur talking about. If not have them call the Hattiesburg, MS store.

Actually yeah that does sound about normal. There are of course alot of variables when it comes to battery life. What you actually use and leave running, how much and how often you use it and of course how strong a signal you might have or not have.
I get better battery life than that however there are a number of things I remove from my phone that I do not use and I shut just about all syncing off. Naturally that will make a difference.
I see so much about battery life on our phones and what confuses me is what do people expect? Really these smartphones are just about like walking around with a laptop in your pocket. How much time of continuous use can one expect to get out of that? I know most laptops you would get maybe a few hours of use on the standard batteries after a few months of use. I guess thinking of it like that are we really doing that bad?
Sure I'd love to see a battery that will last 2 days and I can use my phone constantly but at least at this point and time that simply not going to happen.
I know you are not complaining here but I just wanted to vent a little bit lol

you have to have something running constantly on that phone. might want to pick up a app in the market and check what is running that thing like that. system monitor is one app and there are others as well. either that or you just have a bad battery but not likely

Try watchdog lite. Just don't set it to update constantly, it'll eat your processor if you do.

Okay, I know I'm not from the TB side as I have an Evo, but one thing to keep in mind is that if you leave 3g/4g turned on, it constantly tries to find a superior signal. Use wifi where available. Also, turn 3g and 4g off when you don't need them, and don't leave stuff set to sync on its own. Other things that can be done to improve battery life are lowering your screen brightness and adjusting the screen timeout/sleep interval. The lower each of these are set, the more battery you will save. If your screen is always on, it's constantly drawing battery, obviously. Also, in my experience, the HTC charging kernels have a tendency to be a bit finicky when it comes to charging 90-100%. Sure, your phone may show 100% charged, but if you pull off the charger and it drops 3-8% in the course of 5 minutes, it clearly wasn't 100% charged to begin with.
However, if you meant to say that you were following these guidelines and still having this issue, I would say you very well may have a defective/weak battery.
root your phone and download imoseyons leankernel.
i can get over 24 hours of battery time pretty easily as long as i'm not using it heavily, and that's with an overclocked cpu to 1.4 ghz.
i have been turning APN off via extended controls and my battery life has gone to bearable to good! I am really happy about it b/c the widget works perfectly and turns on and off in virtually seconds, and completely turns off all radios other than the one for calls and texts.
So until I have root and am able to adjust the battery life in that way this is working great.
here's mine on das bamf 1.2 and ziggy's april 6th kernel at 1497/368 on smartass governor w/ 2750 battery...mediaserver was me streaming mecanto over 3g for 4-5 hours, also used pandora over 3g, but only for an hour or so...no wifi used in the last day..radio set to cdma auto so it doesnt look for 4g.
brightness and sync on whatever I want, I keep beautiful widgets at 15 minute update, not sure anything else syncs...mail seems to sync when I switch to the screen with the mail widget or whenever I open the mail or gmail app..

Yea, I just posted on another board that I will not be able to stay with this phone. Im going to have to shell out 600-700 for an off-contract Bionic. My phone was 100% at 7AM this morning.. After sitting in the car all day at work, 10 hours later, it's down to 75%. I figure that's not bad.
Well in the 4 hours since Ive been off work, Ive made ONE 30min phone call and sent 20 texts. The phone is dead. Didnt do any surfing. One call, twenty texts.
This is unacceptable.
EDIT: Yes, I checked the partial wake usage and nothing is running in the background. I have nothing syncing either. There's only like 5 things in the battery info screen.. Phone call, Display, Phone Standby, Cell Idle, Android System, and Android OS. The single 30 minute voice call accounts for 47%, 30 minutes of Display is 21%, and the idle and standby are the rest.
ive called verizon about the hybrid prl they just lol its an auto update they cant just push it to your phone maybe your in a 4g lte area but im not
So I've had this phone for a week now. Its a nice upgrade from my infuse 4g. But the battery life is killing me. I've tried every Tom.available specifically for the skyrocket and even the one kernel in the dev section. My brightness is 15% and I use juice defender set to every 30 min. I listen to Pandora for an hour and it drops 20%. Yesterday it was dead in 6 hours. Its to the point where I'm seriously considering going back to my infuse. Has anyone else had issues?

Currently have juice defender, 0.2 kernel (didnt update and probably wont for now), and a few apps frozen by Titanium Backup. If I hardly touch the phone, it would last 41 hours. With medium usage, (Wifi, web browse, using poweramp for some time, calls, emails, etc) It would easily last my entire day.
What apps did you freeze?

I have JuiceDefender Ultimate set to balanced, I have only the clock widget running, I have GPS running continuously, (I use Wifi occassionally), I have screen set to about 50% and with very normal usage, the battery is at about 20-25%. I have a good number of email accounts and they are polled constantly, notifications are normal (phone settings), I use the Market app and the browser a number of times a day and I hear the occasional podcast. By the way, listening a podcast for about 1 hour (I use BeyondPod and earphones) results in minimal battery usage (about 2% for an hour or so).
So, I have to say that I am quite happy with battery life.
I know what you mean.
I had a stock skyrocket running in a weak LTE market in New Orleans and it would last like 8 hrs then I rooted and frooze all the bloat ware and de-installed a lot of app that were always using the web. I manually set my screen brightness. And changed the launcher to go launcher. Getting 18-20 hrs lots of moderate usage lte and all.
Yea something is wrong. I don't even use juice defender yet my phone last all day wit like 20% when I get home at 9. I use it to talk at least 3-4 and moderate usage for internet and am in wifi a lot. Youtube umm often..Defective maybe??

How do you turn off LTE?
look in settings, about phone, battery and see what is using all your battery. Battery life is very good on the stock ROM, rooted or not. You might also want to install Traffic Monitor and set it up for your billing cycle properly. Then watch for a few days to see what apps are using data. I do not recommend turning off LTE.
BTW there is already a very good Freeze list of Apps...

I was also having very low battery times on my SR to the point it was draining about 5% every half hour. I checked everything and everything was set properly. Yesterday was ready to pack it up to exchange it and thought I try restoring the phone. After restoring it, I now get excellent battery life. I'm getting about 1% battery drop every hour. Today tested throughout the day and listened to some music, some web browsing, a few FB posting, a call for 20 minutes and have 95% battery life left.

I've had pretty bad battery life here in the DC area (LTE is available here). It'll last about 6-7 hours with very mild use. Maybe I should restore it?
What did you do @ElCamino to reset it? Maybe I'll try that too (though I'll hate having to set it back up again).
Also, I turned juice defender back on today, and I've noticed that it seems to be keeping the device "Awake" even when the screen is off. I have it on "balanced." Can anyone give me a little advice on setting it up correctly. I can't seem to get it to let me open more granular settings.
So I am starting to wonder if there are some defective units being shipped. My wife and I both have a Skyrocket. Mine is great, been using it for 13.5 hours today on medium usage. I currently have 63% battery life left. I am completely stock, no juice defender or any other like programs. I even had No-LED installed and used my flashlight app for about 5 solid minutes.
My wife on the other hand has the exact same setup as I do. She complains she barely gets through half a day with medium usage. I charged up her phone earlier today. 7 hours ago I took it off the charger. She has used it with very light usage in that time and it is down to 60% already. When I say light usage I mean sitting on the table for at least 6.5 of those hours. Often she charges it up while watching TV at night. Takes it off the charger when she goes to bed and by morning the batter is at least half drained.

@jslanger I went to settings>privacy> and choose Factory Reset. Yes i know that you have to reinstall and setup the phone, but I am glad I did. Battery life has been great. I'm not in a LTE area but like mentioned battery was draining quick before.
Also I wouldn't recommend you use a back to restore, just in case that something with OS setup from Samsung causing this.

just to help you guys possibly, i moved some APPS to my SD card last night, at work i noticed mediaserver was second in my battery list and my phone was draining faster than normal
after moving the apps back to the phones internal, the drain seemed to stop, i also wiped the sd card just to be safe as i usually stream pandora anyways , but just another option to look out for
Weird....
So I've been closely following my battery life because it kind of sucks.
I had great battery life at home while on wifi over the weekend...about 18 hours no problem. I recharged it today at work, and was not getting great life during the day while on LTE/4G
Got home, turned on wifi, and the battery drain completely leveled out. I also noticed that while on cellular, the "Awake" bar is solid. As soon as I'm on wifi, it was able to not be continuously awake.
Not sure if anyone can comment on the reasons that this would be, but usually its the OPPOSITE. I really dunno why this would be.
Any help is appreciated!
Here is my battery life. Rooted and haven't froze any of the apps yet.
I know i

Hi, can anyone help me solve this problem. I'm getting poor battery life from my Nexus S (stock 4.0.4) & android OS using a lot of battery. I've narrowed it down to WiFI - when I turn WiFi on, the battery depletes much faster than when I'm on 3G & android OS goes from ~7% to ~20% in battery stats. This is the opposite way around from what I would expect based on other posts, which say that WiFi uses less power than 3G. You can see the effect in the screenshot - for the entire time on this screenshot, I was at work with good 3G coverage & the WiFi point is right outside my office:

Any suggestions?
I agree with you, stock 4.0.4, Matr1x kernel (but I get same results with Air kernel too) and wifi always on = poor battery life.
My workaround is keeping it off and switching it on only just before an autosync or when opening browser/Gmail (I do that with Tasker)
When WiFi is in use what are you doing?

Essentially nothing. I checked the odd email, but for the most part the phone was in my pocket doing nothing.
have you got a background service that only runs on wifi?
also, in my experience, 3g only uses more battery when you're actually receiving data (e.g. browsing, data sync).
to me your battery stats don't look that bad, so my theory is that because you don't use your phone that much, anything that uses just a little bit of battery makes a big difference in battery use percentage.
but then again, I could be completely wrong...

Well one thign is for sure battery will always die faster on the network because most of the time if your in bad service areas it trys to fight for service therefore shi**ier battery life.
But @ Richstant do you disable mobile data manually like. For example because my NS4G is just deactivated on my Epic 4G i manually disable data and re enable when i use something so i save battery life.
I switched my sleep policy to while plugged in now. The difference with just switching the wifi on and off is really insane for me.
The way WiFi works while screen is off is hopeless on the Nexus S. I think it may be exagerrated because of the guzzling hardware as it seems no different on the GN or SGS3, though they dont drain nearly as much (i thought otherwise at first, unsure if it's on a phone-by-phone basis though). WiFi likes to stay on even if you set sleep policy otherwise - look at it funny and it will stay on and drain. This is something that i hope will improve in JB, but i doubt it. For now, best bet is set to Never (or plugged in, same effect) and switch it off manually if you won't be using it for long periods of time.
WiFi uses less power for large amounts of data and even browsing. It's faster, it doesn't need to send extra power and there is less thrashing to find the best signal. Data, however, is technically always there anyway as the radio is always powered, so if it only needs small amounts of constant data, it is often better for battery if you have good reception. This is one thing we i don't think we'll be worried about in newer phones, thankfully.

I'd forgotten about that setting, I'll try it now. In the past it's not worked for me though - the WiFi just stays on all the time no matter what.

Thanks for the info - sounds like it might be just the way this handset is :-( I don't remember it being this way under gingerbread, the WiFi turned off properly when it slept then, and battery life was much better.

You don't have any apps set to auto-upload or backup anything (e.g. Dropbox Camera Uploads, G+ Instant Upload) once it connects to Wifi do you?

Hmm, that option worked fine for me, when I unlock the phone, there's a 1-2 second delay before the wifi icon comes up, if I am not plugged in, that is.
I have latitude on all the time, I am suspecting that latitude is the one that causes my battery drain WHILE wifi is on, since there's just too much wifi hotspots around here, and if latitude is triggered everytime there's a new wifi hotspot discovered, then it will have a lot of updating to do. Using the sleep mode doesn't cut down the number of wakelocks (reported by BetteryBatteryStats) that those LocationServices triggers however, but battery life does seemed to be saved, especially on the days where I rarely use my phone.

I would look at this also. If there is an app that has some connection with wifi (i think this would be done through intents but i'm not very familiar), it may either keep wifi on or awaken it from sleep periodically (where it looks like other apps/features take over and continue using it instead of shutting it off immediately). Maps and something from Android OS or Android System seem to be main culprits if the battery page is to be believed. BetterBatteryStats can help, but haven't gained that much information in regard to wifi - though is priceless in most other areas.
Edit: Didn't see the last post (got distracted lol). That could be it. Note that in BBS you should also look at the number of wakeups, not just the time wakelocked. Obviously you can rack up a lot of wakeup attempts and still show only 1s of actual wakelock, but it adds up immensely from there - particularly when some other apps are triggered because they are notified wifi is temporarily "active" when it shouldn't be. Also, these are my experiences and not coding fact, so take them with a grain of salt and listen to those wiser than I
Well I'm pleased to say I got a serious improvement in battery life by setting wifi to off when not in use (except when charging). I tried that under 4.0.3 & it didn't work, but it seems to work correctly under 4.0.4.
wow, I didn't even know there was a "wifi on during sleep only when plugged in" option. I knew juice defender and other similar apps did something like that, but didn't know it was built into ICS (or CM9 )
thanked for the tip
Hi guys, I am from Peru and I have the team this thread. I want you to know how much they long does the battery if you leave the 3g on with the screen off without using it, the reason is because my phone with the screen off and not much use to me lasting 9 hours and do not know why?

It depends on a lot of things. I think it should last longer than 9 hours with little use, but if you have things like FaceBook or newsfeeds or weather updating frequently, that could wear it down. If your 3G signal is weak, that could definitely wear it down.

thank you very much for the info, I think my battery is damaged. Today I leave with 71% battery in 3 hours and 50% battery low, only had 3g but because data was transferred to a prepaid chip. As I can see if my battery is damaged?
I usually last ~36 hours, data and screen off.
Did you check to see what is using up your battery in Settings? I can easily last for over 24 hours with the display off, or otherwise known as standby mode.

If your keeping it in your pocket and/or in an area where it is going in and out of signal, it will go through battery very quickly. Even spending a hour in a store where you get no signal. I have noticed a more poor signal in my pants pocket vs a shirt/coat pocket. It will show underneathe the battery graph as red under signal. I agree also that having a ton of apps syncing will eat battery on mobile data, also things like gps, bluetooth, wifi on with no connection, ect.
I normally lose about 25% during a 9 hour work day, with 4G on. But I don't run alot of apps that need syncing (all set to manual), only have google contacts syncing on, and I'm in a constant good signal area. That's with a few google searches, email checks, and forum checks.

Just curious... are you running CM10? I've noticed that even though my screen isn't on I was getting a ton of battery drain from the screen regardless of kernel used... so I went back to Tweaked.
Now I get a 1% loss per hour with WiFi & sync on and WiFi calling active when the screen is constantly off.

it's $20: http://www.amazon.com/QCell-Samsung-3850mAh-Extended-Battery/dp/B006SKHIKG
And seems to have more juice than the default battery.

Just FYI, the user had a Galaxy Nexus GSM I9250 and Galaxy S Blaze and verified it worked. Hopefully the extended Nexus battery isn't bigger in size. Just double check the size of the Blaze's.

sounds like it's a weak battery. might need a new one.
I got my AT&T One X a month ago. The battery life has been pretty good, considering the specs of the phone, but I've never been in an LTE area until last night. I'm running AT&T/HTC's stock Android 4.1.1 firmware, and I typically get through the day with no problem and have some battery to spare at the end of the day in an HSPA area.
However, last night, I was in an LTE area for the night, and I noticed that the battery drain was outrageous. As soon as I got into the LTE area, the phone started getting really warm around the camera and I noticed the battery drain was about 10% per hour. I never let mobile data on all the time, I switch it on when I need to use it, and then turn it off when I'm not using it. I was using the phone a bit more heavily than normal, but it shouldn't have been enough to kill 80% of the battery in 8 hours.

On the graph above, I entered the LTE area shortly after 5PM, and you can see where the graph starts dropping quicker, and then around midnight when I left the LTE area, it levels out again. Also, the first break in the mobile network signal was a reboot. Prior to that, the phone was warm all the time and the battery was draining quickly. After the reboot, the phone would only get warm when I was actually using mobile data, but the battery drain was still happening.
I went ahead and did a factory reset on the phone afterward, to see if there may have been a rogue app or setting causing the problem, but I'm not sure the next time I'll get to an LTE area to check it out, but I'll try to report back soon.
Has anyone else had this happen or know of a cause or solution? Thanks.

I dont have LTE with my provider but from what ive read this is normal.
As with many battery issues, you will probably hear vastly different experiences from different people. I've had LTE in my area the entire 1+ years I've had this phone (area had LTE since before the phone was released). I seem to have good coverage in the area, and can often get 48 hours (or a little more) on a single charge with light usage. Drain while idle on LTE for me does not seem significantly different then when in a non-LTE area, or on WiFi (around 2% per hour).
Its possible you were in a fringe LTE area, which would drain the battery much more quickly than an area with good reception. But I would not describe the type of drain you experienced as "normal". Or at least not what is intended or expected.
Since the phone is stock, there isn't a lot that can be done. The stock AT&T ROM is locked out from turning off LTE (which would be one workaround). Flashing a different ROM or radio might help. But those require root, bootloader unlock, etc.
I was in Baltimore, which has had a fairly mature AT&T LTE network for about a year, IIRC. I was in downtown most of the time, which shouldn't be a fringe area. At one point, I did a speed test, and got 17 mbps down and 9 mbps up. I know there's not much that I can do about disabling LTE using the stock ROM, but I shouldn't have to use a custom ROM; this type of drain shouldn't be happening.
I'm pretty sure you can switch LTE off on a stock ROM. Enter the following code on your dialer keypad:
*#*#4636#*#*
A menu will appear, select phone information.
Then scroll down and you'll find a drop-down menu. Open it and select gsm auto prl or wcmda preferred.

You can, but it won't stick, since AT&T has this setting 'locked'. It will reset itself to LTE on at the next reboot.
I'm just curious but did you have the Power Save turned on because when I use Power Save and I live exclusively in an LTE area it would last me about 48 hours on a single charge give or take a little. One thing you can consider is checking to see if you have applications running in the background trying to use your data even though you may have it turned off.

You mentioned you used the phone a bit more heavily but never mentioned screen on time. 8 hours doesn't seem all that bad to me if LTE + 3-4 hours screen on time.
Screen wasn't on that long. Take a look at the screenshot in my first post.
Also, in the meantime I've found an APN setting which is supposed to just use AT&Ts HSPA network and not LTE.

Hows connection stability with that APN? I tried using it back in the day to circumvent at&t's LTE only setting and it was very unstable. A few minutes with the screen off would also turn all data off.

I haven't had any problems with it yet. A few hours with data on the past few days, and I haven't noticed it drop. I'll keep you posted how it works the next few days.
