I have a friend that sent me this message today, which sounds like a great idea:
I've been messing with setcpu and trying out some underclocking profiles. Underclocking while the screen is off as well as reducing the CPU power has gotten me 75% battery left after 8 hours. This is with constant emails but no wireless, bluetooth, or gps. This is better than I was getting under windows mobile.
Using a complete black background as your desktop background screen also helps with battery life. The black areas dont use battery power.
If you install one of the cpu meters, it will show that there is automatic underclocking... mine says it has been running at 100MHz for 76% of the time (1 day uptime).
Android System Info will tell you this.
Now, I'm not sure if this is the same as what you are doing though.
You know, I believe that is correct. I don't know if he is getting any advantage or not. I'll forward the info to him and see what he thinks.

That only helps if you spend a significant amount of time on your phone's home screen or hit buttons a lot when the phone is in your pocket.
I've found that the best way to save battery life is to use manual brightness. Auto brightness is just too bright. In fact some newer firmware hidden on samsung's site does make auto brightness a bit dimmer.
Using manual brightness I get about one hour and fifteen minutes of screen time per 10% of battery. I get about an hour per ten percent at work, where it's brighter. I get about half that with auto-brightness.
I think one good way to test which i am going to do to tonight is charge your phone and right before you go to bed unplug it and let it run through the night and in the morning see what sucks the most battery. i'm going to assume it should be "phone idle" but if its cell standby then something is sucking data, someone correct me if im wrong .
Just flash to jh2 out jh3. I'm on 16 hours and have 50% left

I know my 8525 (a precursor to the tilt) had excellent reception. It was far better than average. This captivate is not as good. In my experience the captivate has average reception. I've had much worse.
Well, my buddy that told me about the topic I used to start this thread just stopped by.
He is playing with an Android 2.2 ROM that has been installed on his HTC HD2, which also is undervolted a bit. And of course, tweaking with SETCPU>
He said he is getting email and messages etc as normal; has full CPU and good power when using it (BTW...the Quadrant readings on his phone is coming in at over 1700). His phone has been up for 24 hours, 15 minutes when he stopped in, and he had 58% battery left. Before he started tweaking (and I think before the undervolted ROM), he was getting 11-12 hours on a charge.
Sounds pretty good to me.
So after 2 hours and 3 minutes...my battery is at 25% ...since starting to write this message it has dropped 3%. The display is taking up 80% of use. Screen brightness is about a centimeter from the far left side. Screen has been on about 90% of the time...however...after only 2 hours and now at 23%...I'm a little concerned. Any suggestions?

I like to have my screen on while at work. It would be easy to just turn it off ...I'm hoping for another workaround. I thought these screens were supposed to pull less power.

I does pull less power but having it on all the time while at work will still drain your battery pretty quickly and why want you have this on all the time?

It was more of a test to see how long it lasts with the screen on. I am a little concerned though because lets say I'm sitting in an airport or on a plane watching a movie(I travel for business). My old Droid X could get me through that. But I'm thinking that it wouldn't be an option if my battery is dieing after 2 1/2 hours with the screen on.
Coming from the droid x, kernels weren't an option so I don't know much about them. Would an enhanced kernel be able to help with this drain or am I SOL?
I'm having battery issues as well and hoping someone can help. I heard people are getting great battery life with this device, but so far mine is about the same as the thunderbolt was. My charge says its mostly the display taking up the battery life, but I've done all I can to help this. My screen time out is at 15 seconds and my brightness is at about 20%. I am running ADW EX but I wouldn't think that would cause this. Anyone have any other ideas?

lol...yeah. I had an extended battery for my Droid X...but it didn't triple the size of my phone haha
The screen does use less power, but a significant amount of the power savings comes from displaying black, as black uses no power on the display, where it does for LCD displays. For me, the Display is usually responsible for 65-80% of the power drain, so your usage seems somewhat normal. Custom kernels can help with drain some, but what can be tweaked with a kernel won't help with the display draining the battery.

Potential Solutions?
So besides reducing screen timeout to minimum, turning off background data, and cutting off literally every single connection (wifi, BT, 3g/4g, gps, everything) except 1x for calls and texts, removing bloat, are there ANY other measures one could take to enhance the stock battery life? I find myself talking on the phone for roughly 1hr per day but I do send nearly 500 text messages daily thus my screen is on a good portion of the time. I have to charge this phone twice per day at 2.5hrs per charge, it sits near an outlet for 5 hours a day heh... In fact even though I live in a 4g area I can't really use that feature because it beast's the battery down like a ravenous monster even with ALL other services disabled, not making calls, just texting and syncing email.
Task killers:
To me the task killing programs (ATK, ATM, etc) do actually kill background tasks and sometimes even services depending on your particular settings but since they just restart automatically does it not use MORE cpu time to re-run the damn things than just leaving them in the first place?
Launchers:
I have found no significant difference whatsoever between battery life under TouchWiz and LauncherPro. If anything its worse with LP because of the nifty graphical effects.
Kernels:
I'm pretty sure I read somewhere people were experiencing better life with the v4 voodoo kernel however I've noticed no difference at all there either with regard to battery life.
Running the phone with no services and charging it twice daily seems fairly extreme, eh? The extended battery is tempting, but one thing that attracted me to this device was its slim design. I don't care if its a little thicker and all but that ext battery is a freaking monster! Forget having a case with it too, at least for now.
Thoughts, suggestions?

500 text/day? Wow, you must be under 20 with thumbs/pointing fingers of steel! If your average text message takes 30 seconds, your screen is on and the screen/keyscan interrupts are running full bore about 4.5 hours a day just texting...when do you have time for Angry Birds?
Maybe a thin white text on black background for your screen theme? Just kidding (sort of), but I'm amazed at the talk/text times; gettin old, I guess!

Seems like this explains while some report great battery and others terrible times...depends on what somebody considers "normal" to "light" usage and while some consider "texting" light usage if the screen is on black text on white background the whole day, there goes the battery stats. Same with screen on sitting doing nothing (maybe displaying time)...
Should "Battery Life" be normalized or adjusted something similar to "Time Between Charges" divided by ("Time Screen Display is On" times "percent White pixel counts")? Are there any battery stats / device stats / display stats that can help figuring out a "Battery Life Index"?
Sorry for the random thoughts....

Actually I've been keeping track and the screen is on 3-4 hours per day, plus the haptic feedback, interrupts, etc. Doesn't take me anywhere near 30s to send a text message, few seconds TOPS for most of them and I never said it was light usage haha. Just asked if anyone knows of other measures I did not list which I may employ to extend it more.

The vooodoo kernel will help a bit as it uses a much more optimized file system so your phone will spend less time cache thrashing and reading/writing large downloads.
Essentially though it is down to how long your screen is on and how many accounts you have syncing in the background, also if you don't need full 1ghz for texting/calling smoothly then use setcpu with an ondemand or interactive type scheduler and set the max to like 700-800mhz...

This....
BUT i will say that the battery life on this phone takes a great big dump on the TB`s battery, now thats a bad battery life, i would consider myslef a heavy user i make around and receive around 100 calls a day, around 100 emails and around 75-125 texts per 8 hour working day
i can get through my day putting my charge on charge ONCE for around 30 mins, my thunderbolt had to be plugged in most times, 2-3 hours max for total battery death ( 3 hours is extreme generous, was more like 2 hours ), i carried 3 batteries with my thunderbolt.
The charge for me is great, on a par with my old galaxy S for battery life, if only they coukd give me iPhone battery life, for as much as people dont like the iPhone, it sure does sip the juice
Myphone ie ed2 stock, no rooted.....YET im waiting for a stable CWM
I am opening this thread to facilitate skyrocket users to share their experiences on getting most out of one charge.
I generally prefer something that shows percentage on top since the battery display does not provide detailed info.
I have tried few free aaps and finally found the best one. It is '2x battery' app. I used to loose 4 - 7% per hour in standby mode. With this app, It gives me 1-2% most in burn in hour. While writing this, I am 36% after 17 hours of regular use.

im at 11 hours and have 89% left using Juice Defender plus..
The only problem with JuiceDefender is that if you use messaging apps like Kik or WhatsApp, it will make it so that you don't receive the messages unless you have your phone active, making your phone pretty much useless.
I dont buy anything til I see proof of screen time and battery use screens.
Just got the phone yesterday, but I must say, coming from the epic 4g touch where I was getting 25 hours with 5 hours screen on time, it doesn't look promising.
But to be fair I haven't underclocked, undervolted and all the other tricks yet. Properly working sleep mode is essential.

I will try the 2x battery,
I use JuiceDefenderPro; custom profile
After 7 hours on battery, I am at 90%.
light calls, 1-bar of signal on 4gLTE, apps grab data every 15 minutes.
Anyone see results w/ underclocking?
I am using Antutu's CPU Master (Free), but my results have been inconclusive (sometimes uses less, sometimes uses more.. can't tell). I am considering getting the paid version of the app (or SetCPU or Android Overclock) to try the screen off profiles.
I use set CPU to underclock when the screen is off and when battery is low. In my experiences the savings are noticeable but not major.
With set CPU, juice defender, and a de-bloated rom I usually go to bed with around 30% battery remaining. That's about on par with my nexus one running cm7.

I haven't really had issues with the battery on my skyrocket. Then again, I'm not I'm an LTE area but you can pretty much expect bad battery life in an LTE area. Regardless, I have noticed something odd about the battery on my skyrocket, and maybe someone can confirm my observations here...my skyrocket tends to lose battery fairly constantly at first up to about the 80% mark then slows down the rate off loss of charge and I notice another huge slow down in drainage at the 30% mark. I've seen this repeatedly no matter what I do. In other words, screen on or off, I tend to see this happen. I'm not complaining as I think a 20 hour battery is great when using it heavily. And I kind of think of the slow drainage at the 30% as a nice perk. I'm running it stock so I can't chock it up to anythnng other than the phone. Any thoughts?

Why does everyone say this about LTE? It is simply not true. All LTE does is give you higher bandwidth with less delay. Wan't good battery life, run a custom ROM. I am running the ICS v4.1 and I must say it is much better than anything else I have tried. I keep 4sq, FB, twitter and gmail all running in the background along with BeWeather updating every hour.

Everyone says that about LTE because (from what I've read) running LTE requires more power due to several reasons. I did a quick search and sprint may be a great indication of proof of the power consumption of "4g" from what I've read their phones disengage wimax when not in use in order to conserve energy. If LTE is faster and operates at higher frequencies (if I'm not mistaken) then it should require more energy. I could go outside the box and come up with some equations that relate frequency to energy (they exist) but I will admit I don't know if they can be applied to the circuitry in phones though I don't see why it wouldn't as the theory is sound. In any case, yes running a custom rom will do wonders for battery but some of us haven't taken that plunge yet. As it is, my stock skyrocket is doing great for me lasting 20 hours. Im out of the house at 6am and usually don't get home till 8 at night. It makes it through that with ease. I'm happy with that. Bring on the LTE, I'll cross that battery consumption bridge when we get there.
Can someone please help me with my horrible battery life on my infuse? I cant make it a whole day on my phone. I don't play games on it at all during the day because I work. The only thing I do is make calls and text. I had 100% battery this morning at 6:00am and it is now 1:30pm and I am down to 12%. I am running the latest version of catyrom on my phone and it was supposed to increase the battery life. My phone is less than a year old (probably only 6 months old if that) so the battery on it should not be shot. Any help would be awesome!
THANKS!

Should not be like that. All the uckl2 base ROM have very good battery life.
Try a reflash. I would go into cwm, wipe data, wrote cache, wipe dalvik, fix permission, go to mount, wipe system, data and cache. Re flash ...i would try Another uckl2 base ROM then go back to caty if battery seems better
Buy Juicedefender Ultimate, set it up whichever way works for you. I couldn't tell you about Catyrom and the JD AOSP helper compatibility.
Buy and set up SetCPU to downclock your CPU when your screen is off, and when your phone's charge goes under a certain amount. Change your governor to conservative, ondemand, or smartass. Those will help. You could try undervolting, but be wary of doing it too much.
Look at your battery useage history and work out your app issues from there.
A faster microSD card wouldn't hurt, class 4, 6, or 10 would be better than a class 2, if you're even using a microSD card. Faster read/write means less time reading/writing.
If you need even more power, you could always go to 2G networks if Catyrom allows you to use them. From my experience, it will interfere with speakers on other devices. I have ~8 pairs of speakers in my office, and the interference drives all my co-workers nuts.
And you could always carry a spare battery, which isn't the best of options, but it's a sure fire way to go on
Reduce the number of widgets you use, reduce the number of screens you have, remove redundancy in your apps, and turn off live wallpapers.
Turn off auto brightness, and set it down to lowest valuable that is useable, then bump it up just a bit more. Then set your timeout to something conservative such as 15 or 30seconds or 1 minute.

Thanks! I downloaded juicedefender and setcpu both. I had seen juicedefender in the market but was a little questionable about what it does. but I will see what and how good it does tomorrow. I have my phone charging right now so I will upload a pic of my battery life tomorrow around 3 so we can see how my phone is doing. When I looked at the battery usage when I plugged in my phone it was on for 7h 34m 24s on battery and when I plugged it in I had 6% battery. I really hope that this works. like I said all I do is text and call during the day.
Thanks again!

JuiceDefender, to put it shortly, will kill your data connection/wifi/gps automatically and will enable them again on a schedule.
Those won't interfere with your texting or calling, but it will interfere slightly with your MMS. You'll have to wait for data to be re-enabled to download pictures/videos.
You can set up a schedule for work to be on a more frequent basis than the one when you're not at work, and once you set the battery threshold and the "ignore on low battery" function, it will stop all schedules once the battery reaches that point.
It will re-enable data/wifi when you turn your screen on so you can use it.
That's about most of what it does and it does work very well.
If you'd like, you can get cheap spare batteries from ebay. They mostly ship from China so they take up to a month to get to you, but they're very inexpensive. I just got my 2200 mAh battery (it fits just like the stock one) and it's not even broken in yet. It's 2 PM where I am and I unplugged my phone at ~8. I'm still above 65%. I don't tend to have very restricted battery use like some folks, but I do look for ways to reduce the battery waste. Most of my stuff works when the phone is in idle/deep sleep. I haven't done much of anything today with the exception of a very few calls and a few texts, a little surfing, and I downloaded a CM7 update from the CM7 port's thread.
When it's been broken in it should do better. CM7 isn't as battery friendly as some other ROMs but I like it very much so far. I have been furiously debating whether or not to move to Zeus ROM, as it seems like the big boy's Infuse ROM right now but I can't tuck away CM7 just yet
EDIT: Another, probably very minor, battery saver would be to download and install Adfree. It reroutes all outbound requests for advertisements to the device itself, so those don't download data and you don't see ads. Instead of them possibly keeping your scheduled data connection on for longer while they download (or pumping up your data useage), they never go outbound because they don't require internet access once checked against the HOSTS file.
Also don't forget to do what qkster advised. Bad flashes do happen, and you could have just had a bad flash.
Bassman--What does about phone say is eating the battery?
Sent from my SAMSUNG-SGH-I997 using XDA App
I have never gotten what I thought was decent battery life out of this phone... I work as a field tech so this phone is my office... Serendipity gave me the best battery life of any rom I've tried and I've tried several.
When I first got it I used Infused rom I would average 3 to 4 batteries a day. When I went GB roms that dropped drastically to 1-2... Serendipity would get me through the work day (8-10hrs) and home w/ a little to spare. Lately I have been bouncing back and forth between caty and zeus averaging 2+ batteries a day.
Might add I received my phone as a hand me down from someone at work. He only used it for a few weeks but kept it stock.
On any rooted ROM, i usually use tibu and delete buddy now, facebook, att, tether manager, devive update manager, etc..every possible background crap.
Every user is different, but with just calls and text, is not unusual for me to have 2-3 days before a charge.
Data sync and wifi off when not using data
Rxnelson the about phone says display. But that is the case on almost all phones. I have my auto off set to 1min

You can also try following basic methods:-
1. Turn Off: GPS, WiFi, Screen Rotation, Bluetooth, APN, Vibration, Animation etc.
2. Minimum Screen Brightness Settings
3. Minimum Screen Timeout setting.
4. Dont install Widgets based apps on home-screen
5. Kill the un-necessary background apps from Task Manager.
6. Use black theme in apps.
Thanks

Something I've found helps a lot is rebooting every morning. I'm running Zeus and noticed that the first day after a reboot I get great battery life (light- to medium-use would leave the battery at 50% after 12 hours). By the second or third day, I'd barely make it through the day. Since I've started rebooting every morning my battery life has been great. I also used BetterBatteryStats to help figure out which apps were keeping my phone awake. I learned that the Stocks app runs in the background waking the phone regardless of settings. Juice Defender is really a waste of time - you'll get better battery life by figuring out what's killing your battery and getting rid of it than having Juice Defender disable all of your phone's features when the screen is off(while using battery itself).
Man your battery life shouldn't be that bad. If it isn't a bad ROM flash then you could have a bad battery. Sometimes batteries die after a few months.
I did a lot of testing for apps and whatnot to try and see if I could maximize battery life. I tried all the juice defender and similar apps and didn't really like how they were killing off my services when the screen was off.
I found out that the main killers of my battery life were specific apps. When I used email apps with IMAP push services I noticed that they would kill my battery because they kept preventing my device from sleeping. I sometimes need about 18 hours in a day before I can charge so I really wanted to maxmize the battery as much as I could. I monitor new apps when I install them. Some seem sneaky so the battery stats might say that the app is only using something like 4% but it is also making the Android OS keep alive and use a higher percentage. I have about 70 apps installed but deleted most of the apps that seemed to kill my battery. In an 18 hour day now it is common for me to have at least 50% or more battery left over. It did take me a while to get this kind of battery life though. I was getting pretty frustrated for a while.
I'm running stock GB 2.3.3 (Rogers) and I am on the Bell network in the Great White North.
so as it may be known, i came from an iPhone 4S and traded that for an HTC One X, i've had it for a little over a week and i really like it a lot BUT (you knew that was coming i think..) the battery is below par, i get about 3, on a real good day 4 hours of usage from a full charge. i only auto sync mail, screen is on 25% (also tried auto for a few days), when at home it's connected to WiFi, data off and when i go out the other way around, GPS and Bluetooth are off at all times. the main thing i do on my device is Twitter, Google+, Facebook and Instagram, + some light browsing the Internet. i understand the screen and processor take quite some battery but it's not cool to only be able to use the device about 3-4 hours before running empty. emailed the guy i traded with and he said he got about 7hrs, which would be awesome after dealing with 3-4 ;}
i am using Nova Launcher Prime, but prior to that when i ran Sense the battery was about the same. may just revert to stock to see how that will affect the battery, even though i will miss my widgets and setup. i also emailed HTC and was considering going to AT&T but since i traded the device i doubt they'll be much help.
what do you guys get... and what if anything did you do to improve it ?
thanks.
How much screen on time? 4 hours is nuts. I easily got 24 hours on stock, with light usage, maybe even a day and a half. The 2.2X versions firmwares seem to get better battery life. Just this morning I had just under 50% battery left after 24 hours, with 1 hour screen on time.
If screen brightness in on "Auto" turn that off, and set it to something like 40-50%. That should save you some, but doesn't account the type of battery drain you are talking about.
Might be some runaway processes. Or any possibility you are in a fringe LTE area?
on screen time is what i was reporting, round about 4 hours -which yea is pretty horrible i'd say. i even have the screen brightness lower; 25%. checked the processes and for what i know nothing out of the ordinary, but i'm a novice Android user so.. prior to yesterday i only used 4G when out, so at home i stayed on WiFi.
battery stats now:
- 76%
- 5h 8m 54s on battery
- screen on 59m 28s
Screen on time of 4 hours very normal, and its good for a smartphone. Everyone uses their phone differently, of course. But 4 hours of screen time gets most people through a day, and charge overnight. What type of screen on time did you get with the iPhone?

Your stats are very normal for this phone model. The One XL screen is gigantic, but isn't AMOLED and as such uses much more battery life to power than some other Android devices. I get ~3 hours of screen on time in a days use of battery, and that is about 10-15 hours away from a charger. From what I can gather of your usage, if you are looking to extend your battery life, the only thing to do is leave the screen off more.
Do you flash custom ROMs? If so, try a custom kernel that allows you to change the CPU governor and clock speeds. The processor in the One XL maxes out at 1.5GHz by default, but you can underclock it to 1.2GHz with no noticeable detriment to performance. Also you can set the minimum frequency to an even lower clock speed, which allows the phone to use even less power when idling. Finally, make sure that the CPU governor is set to Ondemand. Powersave actually doesn't save as much power as you would think!
my favorite part was when he compared a tiny 3.5" screen to a 4.7" screen and expected the same battery life, even though it is roughly the same
Firstly, 4 hours screen on time isn't bad at all. I'm sorry your only reference is an iPhone.
To get 6+ hours of onscreen time with this phone like I and many others get you will need to do two things. Firstly, flash a custom ROM. CleanROM 4.5 is a good one that's as close to stock as you're gonna get. The second thing you need to do is turn off auto brightness. Leave the brightness set at 35% - 40%. This will improve battery life immensely. And no, 40% brightness is not dim.
Happy flashing!
10-12 hours up
5hrs 15mins screen on
Everything synced

with my iPhone (GPS on always, WiFi always, screen on about 70-80%) i got an average of 6 hours with peaks of 7. 4 hours with the HTC One X is on a good day.
i did not flash a ROM since i can not unlock the phone (yet). where i compared, referred to the iPhone is based upon the previous owner who said he usually got 6-7 hours on screen per day. it's uncool that people not live by the rule if you don't have anything nice to say, don't say nothing... i'm only trying to get some help here (luckily most members are helpful... i'll try and ignore the others) and my other reference would be a BB Storm, which lasted very long, but the device wasn't very exciting
i'm following the thread where rooting is discussed but i believe there's little progress. AT&T is also not pushing Sense 4.1 (yet, mine has 4.0) and ICS 4.0.4.
just spoke with HTC and they agree it's too short and are willing to exchange battery... downside i would be w/o a phone for 7-10 business days. might swing by AT&T and discuss, "issue" is i was not the original buyer.. he (HTC rep) stated they might give you a loaner (i doubt it..) we shall see.
thanks to those with positive feedback.
so far..
click here for today's results --16% left.. slightly over 3hr on screen time.

It really depends on how you use your phone, and not all screen-on time is the same. 4 Hours is screen time is pretty good, and pretty on par with what other users on here have observed. The phone is new to you, so I bet you are using it like crazy. If that use includes a lot of internet, playing video, or games, its going to use more battery than some other activities. I don't know if a replacment is going to make you any happier.
You also have to consider, aside from a much larger screen, its also much higher resolution than the iPhone. Pushing all those pixels by the GPU takes power. The CPU is also much faster than the iPhone (and just about any other smartphone except the Galaxy S3), again using more power. Screen time may be less, but its doing so much more in that time.
4 hours, if I made would be somewhat acceptable, yesterday I had a little more then 3. I do not play game, I manly do social media & a little surfing..

my battery would last over 24hrs until the OTA 2.20 update now im lucky to get 12hrs out of it. Did they change something in the update?

The 2.20 OTA has an new radio. So its possible that the new radio happens to result in worse reception (and therefore battery life) than the previous one. Newer radios do not always get better results for all people, as its very geographically dependent.

Thank you for the reply and yes the radio looked like it was a new one and in PA i dont get that great of service everywhere.
Yeah, 4 hours of screen on time is normal so I definitely don't think you have any sort of defect. Signal strength also has a lot of impact on battery life. Keep brightness as low as possible while still being comfortable to your eyes (battery life isn't worth putting extra strain on your eyes). I use an app called display brightness that allows you to change brightness by swiping across the statusbar. I keep mine at the lowest level and just swipe a bit to increase it when I need it and then swipe it back down when I'm done. A custom rom could help some. If nothing else, root so that you can use something like better battery stats to give you more info on what's happening behind the scenes so you can make some adjustments. Although I'm not one to push using this, you might want to install something like juice defender to see if it helps. Verify you don't have some app running in the background unnecessarily chewing up cpu use. Note though that just because an app is running in the background doesn't mean you should kill it. As long as it's not doing anything, it's better for it to be running than to have to load it up (especially if it's an app you use frequently). A couple of other things to verify, don't use push notifications / syncing (I keep background syncing off a manually sync (well, I use Tasker to sync things at different times of the day)). If you can, use wifi. If wifi isn't available, turn it off. Also make sure wifi notifications are off and that you aren't using 'best wifi performance' (both under wifi advanced settings).
I'm sure there are some others I missed but hopefully these help and at least give you a starting place. No matter what though, enjoy your device and don't obsess too much with the battery. Once you've gotten over the 'new toy' syndrome, you should get a days use out of it. I pretty much take mine off charge in the morning and put it on charge before going to bed with around 30‰ left. Sometimes more, sometimes less. 3-4 hours average of screen on time, 30-60 minutes of calling.

Np. Been using it since early on and it continues to improve. One of those handy must have apps.

update.
went to the AT&T Device Center (did not know it existed until the regular AT&T store told me about it...) they played with my phone and concluded that the battery was draining too fast while using it, so w/o discussion they exchanged it.
got a follow up question since AT&T did not know, with the iPhones i would let them drain all the way down at least and then fully recharge and leave it on the charger for an extra 2 hours after it being 100%, i *think* that helped condition the battery.. anything you guys can suggest anything for me to to now that i have a new device to maybe improve/condition the battery ?
thanks.
