How can I make my battery last longer? I am using set cpu and various profiles to give me the best optimization I can, however my phone barely makes it 10 hours with light use *1hr web browsing, avid txting, light music listening via music on phone ~ 1 hr as well.* I'm not faulting the phone. I just want to know what can be done to get the most out of the stock battery as I see people getting results twice as good as mine and just done get what I'm doing wrong here.
Thanks for the help in advanced.
I have the exact same problem as you. Are you using unnamed with Enthropy's experience kernal as well? I'm about to flash cm7 to see if I can get better results.

I used cm7 for a while now using UnNamed and cm gave marginally better battey life but
Just use the dang phone . You dont need to do anything special for great battery life. Try a factory reset if theres a problem though. Im rooted on cog beta 4 getting amazing battery life. I talked my mom imto getting this phone over the new iphone and hers is completely stock and she knows nothing and doesnt close any apps and gets the same amazing battery life as i do.
Reset and use it. If you cant get through a day of heavy use the phone is defective.

+1....or you have wakelocks. Find BetterBatteryStats and CPUSpy. BetterBatteryStats will tell you if something is preventing the device from going into deep sleep. I like to use "wakelocks since unplugged." CPUSpy will tell you the amount of time your device spends in each frequency, including deep sleep. For this, you'll need to reset the timers each time you unplug the phone.
Its add easy as flashing cm.... I went 15 hours and still had 60% left. with OC. Nothing else special (aka no juice defender our set CPU). The only trick is deleting everything in the dcim folder (known medias bug ) you'll see 1% battery loss per hour, with fb and GV sync

BBS sometimes misses wakelocks, for even more info, grab the contents of /proc/wakelocks and post them here.
my solution: keep a charger with you anywhere you go
I have a car charger, home charger and work charger (as do most people)
Thanks for all the replies. I'm sure there's go to be a work around for this
Not sure about a workaround. From everything I've seen, the max battery life is around six hours when the screen is on. Basically, if your screen has been on for 4-5 hours, it's time for a recharge.

Well based on all I've read it seems like the battery is a mixed bag depending on the OC profiles, roms and kernels being used with the device.
Is it true that setting a screen off profile in set cpu will cause the device to not be able to enter a deep sleep mode and thus will kill the battery faster?

Not true. It is true, however, that on stock kernels and ones without the "sleep of death" fix, setting a screen off profile with a clock limit lower than 800 MHz can cause "sleep of death" issues. Right now I think only my kernel and the Cyanogenmod kernel have the SoD fix.

Thanks for clearing that up
I'll post here as I don't have enough posts for the development forum yet.
I'm running Entropy's 16th exp kernal, and Cog4 and I noticed my battery draining far too fast, CPUSpy then showed that the phone simply isn't entering deep sleep. I had previously been undervolting with Voltage Control but I uninstalled the program just to be safe, still not deep sleeping. I also uninstalled Widgetlocker, and I don't think I have any apps that would cause infinite wakelock. What are some possible causes of this issue? Just so I have an idea where I should be changing things.
UPDATE: Reflashing the kernal fixed the problem for a while but then I reinstalled voltage control and now I seem to have it again. Uninstalling and reflashing again however, did not fix the problem. I am utterly confused
On another subject, has anyone actually noticed better battery life after undervolting?
Freaking SWEET! My battery lasted 33 hours and 13 minutes! I've only owned the phone for 3 days now and this is off of teh very 1st FULL charge! Usage was between light & moderate. Data sync on, Wifi On, GPS OFF, BT OFF, FB Data Sync OFF, Capacitative buttons set to light up only in the dark & NO haptic touchback...mmm, can't remember what else I tweaked at the moment but I think that's fantastic battery life! I'm upgrading from a G1 that couldn't last more than 17 hours when it was on standby ONLY with maybe 2 phonecalls and less than 20 text messages. I usually only averaged 6-8 hours and with SIMILAR usage in the last couple of days, I've been able to get 33+ HOURS? ^_^ <-- I'm very, very happy so far! This is on a stock root - NO custom ROM for me at the moment...I'm actually digging TouchWiz 4.0 which I thought I was going to hate when I played with the previous version of TW on the T-Mo Vibrant. (yes, my G1 was running CM 7.1 and battery life still sucked and I went through 2 different aftermarket batteries w/o any luck!)
Don't know what the voodoo in the programming is with this bad boy, but I think Sammy did a nice job this time!
The best thing you can do is having "Autostart" to prevent App to start automatically. I saved 25-30% on my SGS 1 and the same on my SGS 2 (i777). My son on the I9000 SGS 2 saved also 30%.

Check for wakelocks in BetterBatteryStats, and if that doesn't find anything, do the following in an Android Terminal Emulator shell:
Code:
cat /proc/wakelocks > /sdcard/wakelocks.txt
or better, using ADB (Google it and if you're on Windows, Droid Explorer)
Code:
adb shell cat /proc/wakelocks > wakelocks.txt
Then post wakelocks.txt here
All the apps,camera n everything works on that rom? ??? I installed cm7 bt now stock it cuz some apps and camera app didn't work.

Hi,
I just flashed SuperClean 2.9.2 (non-voodoo) yesterday, and I love the speed, but it really drains the battery pretty fast. For example, with minimal usage it drains from 100 to 82 in less than two hours. That's a lot worse than the stock settings I had on there before. Since I'm new at this, is that normal? If I switch to a better kernel would that fix it? Any suggestions on what to do or tweak?
Thanks!
[Update] 3/30/11
So after a full day of observation, I've noticed that it seems to go from 100 to 80 fairly quickly (less than 2 hours), but then the rate slows down. It took 4 hours to go from 80 to 62. Then last night I left it on all night, starting at 78 and it is now at 48 (almost 12 hours). Obviously I wasn't using it much overnight, but I wasn't using it much when the initial drain from 100 to 80 happened. Might just be that the meter is not consistent? But at least I know that it's not draining faster than the old setup.
Still looking into the idea of an undervolted kernel. Any good suggestions?
Thanks!
An undervolted kernel might help but who knows... if I get over 5 hours I usually consider myself lucky.
i updated this morning, have an extended battery, and seem to notice massive drains, but i guess with power comes sacrifices

Not sure why this double posted. Must have been my frustration waiting 5 minutes just to edit an already posted post to correct the name of the app....
Each phone reacts differently to ROMs / Kernels when it comes to battery life. Same setup shows different battery life for different people.
First I would use the "Spare Parts" app and see if you can find any app taking up a lot of your battery life and remove it. (included in SC ROMs)
People also report different battery life with different Kernels. You can flash different Kernels that work with your ROM to see if you can get better battery life.
You also may need to remap your battery. There are posts on how to do so. Basically you charge to 100%, shut down and wait for it to show 100% with power off, then boot, go into Terminal gain SU and type bstats. Phone will reboot. This should be done anytime you flash a new Kernel and some do it with ROM flashes too.
Also don't run screen at 100% bright, use auto or something at or less than 30% unless you are in sunlight.
When not in use turn off WiFi and GPS as well.
All I can think of right now

Running not even 2 hrs yet and mines at 70% right now from a full charge, so I feel your guys(gals)' pain. I checked with Spare Parts and noticed that under "Network Usage" there is a "0" that seems to be using up a LOT of juice. Searching it up on google brought me to a possible issue with GSM/CDMA (Time w/o signal issue). I remember issues with this with the D1 and the Eris, usually you could fix it on those phones by turning on Airplane Mode for a little while, then turning it back off.
EC10 is based off a GSM SGS phone if I'm not mistaken, and because of that may make the phone try to find a GSM signal. My time without signal was around 45% this morning so I dug around threads with similar issues with other phones brought me to this Hero CDMA thread: http://forum.xda-developers.com/showthread.php?t=651848 .
Now we do have the same menu as shown here: http://forum.xda-developers.com/wik...sung_Galaxy_S_Series&oldid=13336#Secret_Codes
My thing is that I can't access it using SC 2.9.2. It doesn't automatically go to any of the menus. Anyone else have an issue getting into any of the secret menus?
It also looks like turning the airplane mode on and off seems to work for now.

Read like 20 threads about the "0" and came to no conclusion haha. People just said it means root... and it could mean any app that requests Super User/Root permissions. Who knows though... I'm about to wipe date and reinstall afresh.
I have tried everything. I tried various ROM's, SpeedMod kernels T27, T29, T32, and T39, and the stock ROM, and NOTHING is working! I cleared out my Dalvik and cache partitions obviously, and I caliberated the battery. Nothing is working!
I used the phone for 8 hours today, and the battery dropped to 50% in those 8 hours. I had the display on for 1 hour and 30 minutes, browsing Tapatalk and the internet. I made no phone calls at all. Besides that I listened to music for 45 minutes, but that's it. The rest of the time it was on standby in my pocket. This is running Lite'ning ROM v6.1 and Speedmod Kernal T39. However, no matter what combination of kernels and roms I try, the drain is pretty similar.
I have the stock android weather and news app set to update every 3 hours, and K9 Mail to fetch new mail every 15 minutes.
This is with Wi-Fi off, GPS off, and bluetooth off.
What could be affecting my battery so much? Is there any information I should post here from my phone so you guys could see what is causing this? I can't even use my phone for one day without the battery completely draining.
Well, you problaby already knew this, but the real life-sucker in the SGS II is definately it's screen. Get the brightness down low and make the screen timeout after 15 seconds so that you don't waste any unecessarily battery.
Can't help to much otherwise, just got my SGS II a week ago, still getting to know it myself. But hope that helps abit anyway.
There may be other apps synching in background. In my case fluent news trend to hang around. Check if every app is doing background work.

I can assure you mine is worse, drops to 50% in 6-7 hours, but as the other person has stated, the screen is the culprit, when I used the phone longer than you, I would expect worse battery life.
Gosh how I wish this phone was equipped with more energy-efficient, less bling bling screen. SAMOLED+ is only good for show-off, which I usually don't do.
Theres an app called betterbatterystats on the xda forum. Use that and see whats draining your battery, especially in the wakeloks department.
Updated Facebook? It's raping batteries so hard it should be on the 6 o'clock news tomorrow night. Or, you know, pretty much anything these guys say here.
Try to use Betterbatterystats and see partial wakelocks and cpu spy to see if you have any problem with deep sleep! Also take a look to battery usage and the percentage of Operating System Android

First of all I think you are wrong when you say OLED uses more power than LCD. Remember how these screens work, LCD lets light go through and is completely back-lit all the time while OLED screens emit light from pixels that are not black.
On the other hand, the real problem with SGS2, in my opinion, is the reason phone never goes to sleep. If you take a look at screenshot I attached you'll see that screen on my phone was not on all the time but battery drain continued. Also, "awake" bar is full meaning phone never got the chance to go to sleep.
I have no clue how to fix this, maybe someone with more experience can help. I use to have HTC Hero on which I could turn off "Always on" in network settings and get phone to sleep often and save battery that way.

Display drain about 1% every 4 minutes of browsing, this is in your case 22,5% .
Every 15 min email checking and the automatic update checking from other apps does the rest. There is nothing suspicious with your battery drain.

Bad apps?
I've had bad battery drain for the last week.
I've rooted, romed, unrooted, changed every setting I could. Nothing has really worked. I'm was losing between 5-10% an hour.
Then I just wiped everything and re-installed the stock 2.3.3 firmware and started re-installing apps an hour at a time.
Battery burn was going good about 1% an hour installing about 5 apps in an hour until I installed TM World Clock.
Within an hour I had a 10% battery decrease and Watchdog saying that Event/0 and Suspend were consuming the 90% of the CPU. I uninstalled...it went back to a 1% and hour battery drain for 3 hours.
Re-installed TW World Clock to see it was a fluke. Within 10 min. the phone dropped 2%. and Watchdog started sending warnings for Event/0 and Suspend again.
There might be certain apps that aren't allowing the Galaxy S2 to go into a deep sleep...explaining why the problem is so random among different owners pending on installed apps.
Hi all, I'm new to this part of the xda forums as I had a nexus before, just got the upgrade to the Atrix, rooting,unlocking of bootloader everything went well but I just flashed Aura's from with feux kernel and im getting really really bad battery life, like I'm talking 4-5 hours. There is one process thats really confusing me, its just called "x" and its sitting there taking about 35% battery, my screen is taking 55% battery.
It's getting really annoying as my nexus used to give me about 12 hours and the only reason I moved to the atrix was to get the better battery life that I saw with all my atrix touting friends (they all had 1-2 days battery life) I'm about to flash homebase and see if that fixes it but I don't know whats going on. I have a UK MB860 and I used http://forum.xda-developers.com/showthread.php?t=1196747&highlight=t-mobile+root to root. Pleaseee can someone help!
X is the webtop and there is a fix somewhere for that (doesn't completely work). Just flash CM7 beta. Its much better than any other ROM and has the best battery life. Everything except the finger print scanner and webtop work.
Also I had really good battery on the Ying Yang ROM.

I think I might give CM7 a go you know, I loved CM on the nexus, even after it killed the memory chips it was still good! Im going to try it, is it really stable?
EDIT:
since updating to CM7 and Wiping my battery stats I have some how gained 39% battery!

I've had great battery life on the atrix, now I'm getting a good look at the atrix on the 4800mah battery. I'm a heavy user and I could not get over 24 hours. And now I have 59 hours and I have yet to actually see how far I can take it. Cm7 beta. Juicey....
I find that all gingerbread roms have horrible battery life compared to froyo on the atrix. Cm7 battery is worse but the phone is smoother. Faux 1.3ghz kernel has even worse battery.
Regardless of the radio or magical method of resetting the battery state you use.
1:25 screen time and at 47% battery. Been off the charger for 6:15. It will make it through my 10hr shift with about 20% remaining if I'm lucky, usually I just toss it on the charger.

I was just about to post that lol. Also make sure every time you flash a new rom you are at 100% if not that is a sure fire way to cheat yourself out of battery life. I don't know if I'm just one of "the lucky ones" but I easily get over 16+ hours with moderate usage. I'm running CM7 beta with quite a few things frozen.
Ok so I followed the guide to perfection and it didn't improve the battery life one bit! I'm trying hard to find a t-mobile radio I can flash as I have read around it could be my radio that is the culprit and I am also getting rubbish HSDPA readings, I should be getting full bars but since switching to homebase Im only getting one bar.
Using watchdog I have noticed that the Xorg process is using over 50% cpu which does not seem right to be and I believe that because its a linux process Watchdog can't kill it. Is there anyway of fixing this?
1) Uninstall Tango, Facebook and Handcent SMS if any of the three are installed. They are huge battery drainers and you can find less battery hogging substitutes
2) Freeze any unnecessary apps, I believe there is a thread somewhere in the General section that has a pretty decent freeze list (if you flash CM7, you will have very little to freeze but that's good!)
3) Keep brightness down to a minimum when you can, I've noticed kicking the brightness up rather high can be pretty demanding on your battery
4) Set SetCPU Profiles to something like this...
Screen Off 216/216
Charging 1100/216
In Call 456/216
Battery <20% 456/216
Battery <10% 216/216
5) If you have the proper kernel set the CPU govner to power saver.
6) Undervolt, test yours and never apply set on boot unless you are positive it's stable, mine are something like this...
1100 MHz -50mV
1000 MHz -50mV
912 MHz -50mV
750 MHz -50mV
608 MHz -100mV
456 MHz -150mV
216 MHz -200mV
This way when you're phone is idling with the screen off, in a call or low on battery it is undervolting heavily to save maximum amounts of battery
With this setup I can get 30+ hours pretty regularly with moderate-to-heavy usage (weekdays/non-work days), 22-25 hours with more heavy usage (work days) and close to 48 hours with little usage (weekends).
It all depends on your usage and your phone but I have found this setup here to work fairly well.
I am currently on CM7 Beta, stock CM7 radio and stock CM7 kernel, running at 1100/216 when above profile conditions aren't met. 32% been running since 9 am this morning, it is now 3:15 am, today was a long workday.
I can almost guarantee (almost) that its your rom/kernel combination. Had same problem til I changed.

That will nuke your webtop & fix your problem.
I'm now using faux kernel for CM7 and that hasn't improved anything, in fact I think it it has made it worse. It's getting really irretating because using the watch dog app it always says there is one linux process on every rom I use that is clocking at over 50% cpu usage and It won't let me kill it (probably because it's a linux process), its really annoying me because all I want is my phone to work properly but to enjoy the full rooting experience. I know countless amounts of people with atrix's and they get a full day and a bit out of their phone with heavy usage i can't even manage 10 hours!

Watchdog eats battery like a mthrfckr, get away from that. Install BetterBatterStats instead & look for wakelocks. Which linux process are you noticing with that high cpu usage?
How many hours of screen time do you get in those 10 hrs?
Have you tried with a fastboot wipe & internal storage format prior to installing a new rom? Are you using the latest recommended radio for your phone?

Turn background syncing off if you are using that, and get in the habit of doing manual updates.
Too many times (with ANY Android device) people leave background syncing on and it tries sending/receiving data in a weak signal spot when you don't realize it. That's like a hot knife through butter on a battery.
Leave syncing off permanently if possible! That's a huge improvement right there for anyone...

That's a bit radical, no?
I'd say use Green Power so the phone can update every half hour or hour. It's a smartphone at the end of the day..
Stock battery
I have done everything from Autostarts to managing my processes constantly. I played hanging with friends, got on here, and texted.
I posted an updated battery usage. I have lowest brightness, lowest image brightness, 15s timeout, etc.
i would probably switch to conservative governor vs powersave
This isn't typical battery life
I'd advice you to use better battery stats and cpu spy to se what's causing your battery to drain so quickly
Sometimes I notice "back up" in bbs, and this casus my phone to drain within a day
Hanging with friends does consume a lot of battery, but I play it too, and this does not cause that much drainage..
I have ICScrewed and with a heavy usage, my phone usually last for 1.5 ~ 2 days
With moderate call/text and idle, it lasts for 4 days.

Dang that is high! Are you sure about that? :O At medium usage /w unnamed i only get about 18 hours total. It was similar with ICScrewed too
Holy crap. I'll look into better apps. Could UnNamed be the culprit? Or the kernel?
Should I buy a new battery? The life waslike this for the few days I was stock, I think
I average around 17hr, on a good day I'll get 20h. I also recommend better battery stats, great app to see what's keeping your device from going to deep sleep.
Another great app is lbe privacy guard, you can deny certain apps and games some of the permissions they want (disabling GPS on those that really don't need it etc).
I'm on unnamed so that isn't the issue. Might be the kernel, just check the kernel wake clock in better battery stats to check. I'm on entropy's latest dd, while i do feel i got better battery life on the kernel with the latest unnamed ROM I'm not to sure if it's the kernel or something else.

I'd be curious to see your graph. My battery is dead now, but tomorrow I'm going to get on and upload Better Battery Stats to my phone. I would've paid for it on the Market, but I couldn't find it when I searched. I'm curious to see what other people think. I switched all Powersaves to Conservative. Is OnDemand bad for my CPU as it constantly trips from 500MHz to 1.2GHz? Should I consider going to 1GHz?

I have a hard time believing that. I've done everything I can to optimize my phone and reduce wakelocks and battery drain, and I still never get more than 20 hours on a good day, and that's with moderate usage.

I agree. This is my latest battery cycle of what I consider "moderate" use
What I'd consider light usage (about 10 minutes of voice, between 5-10 minutes of cellular data, 10-15 texts, and about 20 minutes of total screen-on time) I get about 35 hours.
I have managed to almost completely drain my battery in about 4 hours though... Thanks Game Dev Story!

I realized I forgot to turn off data when I'm not using it, but I installed better battery stats and I didn't really see any wake locks. Should I try a different kernel? Any opinions on an efficient one? NOTE: I already got the yellow triangle for using the Odin way, so I'm fine with doing whatever to this phone.
I added my better battery stats shots. I guess today would be called a very light to light day.

I see two very top wake locks have kept your phone from sleeping for an hour..
That is a significant amount.
Also, use cpuspy to see how hard it's been working.
I would try to get rid of those top two wake locks...
Oh crap! I didn't see them until you brought it to my attention. That explains some of the idle drain. I'll look into CPU Spy. You guys have been so helpful!
Your kernel wakelocks had no data, probably due to BBS being a fresh install. A full charge should set a proper reference point.

If something's holding that many log wakelocks, something might be spamming a log somewhere.
I can't find anything to help with those two either. Or would seem that the keyguard might have something to do with text messages, but I can't see anything that would spam the log. Where might I be able to read this log?
Also, I'll post my CPU spy stats toward the end of the night. It's looking like it spends most of its time at 500MHz.

I have been messing around with system tuner app for a while now and I really like the program.
I would like to hear from people who have used this app and their results with various tweaks that this app provides.
in the boot settings menu:
1. forcing both CPU's online: this should technically give you a better battery life, since it puts less strain on on cpu at a time, has anyone had a good exprience using this?
2. Boost app loading: anyone had any significant improvement with this?
My own settings:
I usually clock my phone at 1.5 (on demand governor) even though faux's kernel allows 1.7 max. I put max clock for screen off at 384 and conservative governor.
I have Undervolted before but do not see a very significant battery difference so I just left it alone.
I tried out the autokill option of system tuner, I only tried to kill the ghost apps, to refrain from the cpu from having to keep restarting the phone, but this also seems to kill battery life...In my experience any type of task killer however detailed will reduce battery and does not increase performance, unless you're running a poorly written app that just needs to be killed.
I use three other programs to monitor my phone
1. system pannel: very good at finding rogue apps that kill cpu...I highly recommend the pro version, you can get a history of what has used cpu up to a week.
2. Onavo and My data manger which basically monitor my wifi and mobile traffic, Onavo only monitors mobile network traffic and lets you restrict apps to only wifi. however it does not measure wifi use of data. My data manager monitor both wifi and network usage but does not give you any options to do anything with the apps, it basically tells you what program is using data while on wifi and mobile.
If anyone has found a good balance between performance and battery saving, please do share.
Thank you.
I read some other guy also mentioned the all cpus on thing. im not sure but isnt it the same as making both processors work at the same time which leads to phone overheating? I will give it a try though. from what you noticed, do you like it more with both cpu on or is better the way it was?

I have widget locker and havn't had that problem...I just flashed faux's latest kernel and am in the process of re calibrating my battery, it seemed to jump from 100 to 90 in about 10 minutes!!!!!! now I noticed that happening...but I havn't had time to fully replicate it...i need more time..I believe it might have something to do with fauxes kernel, he mentioned that when screen goes off he it puts the phone into a low power consumption mode, but also has something that when you turn it on, is quick to turn on!!! we'll have to wait and see.
If you've been following this thread, just wanted make a quick update...I want to give you my results with system tuner tweaking. Forcing both cores online is a bad idea. It will literally kill your battery in a matter of a couple of hours. ICS will hopefully be different and utilize the cores how they should be, saving some battery and giving the amaze longer battery life!
On the other hand reducing reducing clock frequency on screen off will help in battery life (obviously).

yes still stock rooted, I put the governor on conservative and put the frequency to 384 or around there, while screen is off.
What helps most I found out is turning off all the radios like wifi and network data, (basically putting phone on airplane mode). Instead of dropping down 15 percent in 6 hours it drops like 3 when I turn airplane on. But like I've said before it's unrealistic I'm always recieving google talk, google voice, facebook updates and I have to have both of these on which unfortunately eats a lot of battery.
I keep switching back and forth between faux's kernel and stock and I'm actually finding stock gives me better battery life for some reason. Even though I set the clock speeds on both at 1.5 ghz.

Major battery drain is the screen, when on eats up all the juice, dimming helps a bit
charge source: usb vs AC charge
usb charging takes quite a while, AC charge quicker (~ an hour)
Also, from my observation, usb charged battery runs out quicker than AC charge
Data Connection, Juice defender helps a lot
turn off sync you don't need, like HTC sense

And they require both a cell connection and a data connection. I hate to pay for more apps...I've already paid for a bunch of apps to control and see my phone's usage of cpu and battery...is the app really worth it? wish they had a lite version

For what it is worth I am running BulletProof 2.3.1 and last night I took phone off charger at 10:00 PM, alarm goes off at 3:30 snoozing every 15 min until 4:15...Battery was at 100% still. It is now 7:00 AM and battery is at 96%.
This was after flashing back to BP around 8:00 PM.
I've noticed the same type of activity when in Airplane mode. Extremely low power consumption - fantastic.
Is it possible maybe to undervolt the Wifi/BT/Mobile radios? Would that make any difference or am I off base here?

You had something setup wrong then I think.. you can change how often in syncs while the screen is off, the default setting is for it to turn on data for 1 minute every 15 minutes. Most people don't need to know things so bad that they can't work with a 14 minute delay(at worst), and of couse the internet is on while screen is on, when you're actually using it.
I thought I would need to use juice defender, but since I switched to bulletproof, my usage last me an entire day. From 8am till 1am, usually with some to spare. The only tweak I made to cpu was to enable 192mhz, it isn't like there is a performance drop, but it did make a notable difference in battery life.
If I wanted to I could use juice defender to get more than one day out of it, and I keep a spare battery on me in case I really need to use the phone.. but haven't really needed it.
