Hi. I know there are hundreds of threads on battery usage, but I felt I have a special story behind my test.
Lately I feel that my battery life has decreased, but I would like some second opinions on the case.
It's over a month now since I received froyo OTA, and I had some suspicions that my battery life went slightly down after that. I used it more to test the new features, so its hard to really know. However, the big problems occurred a couple of weeks ago.
At a party with a friend of mine, a friends friend literally pulls my Desire out of my hand and drops it into a mug of beer! As a joke!!
He had heard me taking about my Nokia 3720 earlier and decided to test it. However, ignorant as he was, he did not see that it was A DIFFERENT PHONE I was holding!
So it took 2 seconds in the mug, and the screen went black, and the phone was dead... Or not really, I took it out and dried it of with my t-shirt, turned it on, and the screen went garbeled green on me...
Decided that it was best to leave it alone, so I took out the battery, SIM and MicroSD, dried them off, put it in my pocket and continued the party.
But I have to admit it was kindof a partypooper for me...
Well, later that night, probably 3-4 hours later when I got home, I inserted the battery and tried to turn it on.. Screen turned on with the familiar white background, and green htc logo.. and some garbeled green at the top, argh...
I took the battery out again, left all the pieces spread out on the kitchen-counter and went to bed.
The morning after (or should I say afternoon ) I looked at the phone, it seemed as it had dried out over the night. So I put in the MicroSD, SIM and battery, crossed my fingers, and turned it on. And it worked fine, like nothing had happened, phew!
But some days after, I am sure that the batterylife has decreased quite a bit, seems to not hold a normal 12-14hour day with normal use.
I did at one point post-froyo (pre-drowning) have it running for 2 full days before charging, approx. 40 hours, not very much usage though..
So, I decided to test it starting yesterday evening.
I let it drain fully (turned it on 1 time after it died, and let it die again). Charged it while turned off, and unplugged it and turned on after approx. 1 hour of full charge (green light).
Now, I have already ordered a new phone (a Streak is on its way over the North Sea as I write this . But I wanted to do the test just for the heck of it.
My girlfriend also has a Desire running Froyo, and I notice she uses her phone WAY MORE for gaming and stuff, and only charges a little more frequent than me.
They are both AMOLED phones, I got mine in Feb, she bought hers in March.
So, here comes the timeline:
@23:30, Turned it on after fully charged, went through all homescreens to activate all widgets. Did not run any programs.
I have no specially data intense widgets, only email and weather (3hr sync). Wifi off, and 3G (H) on always, no active background.
@08:00, On my way to work, Battery indicator (i use *#*#4636#*#* to check battery status) at 88%, recieved 1 email during the night.
Battery usage says: 49% Cell standby, 49% phone not in use, 2% android system.
I have noticed my phone struggling to keep connections while travelling even short distances(pre- and post-froyo), maybe a little worse of a problem post-froyo.
Did not happen today though!
I often need a reboot to get the connection back (Flightmode often works 1 time, but not 2 times. does not activate the second time I try it, just hangs...)
It's not only the data connection, there is no cell reception at all (apparantly).
Maybe I should start a thread on that also, but it is not a big issue for me (this phone is on a free use data plan, almost never use it for calls)
Dataplan here in norway costs around 50$ btw, no other extra costs for tethering and such in norway
@09:45, at work, recieved 2 more emails. now @84%, on EDGE network. battery usage: 53% Cell standby, 45% phone not in use, 2% android system.
not that bad actually... 10:21 "on" time, with 34 minutes active-use time.
Will try to leave the phone alone some more, and do some surfing on it around noon.
@12:55, still at work, used the phone for surfing and gReader for 25 minutes, on EDGE network. Downloaded a BOL revisited episode (podcast), I usually listen to an episode via bluetooth streaming while driving to/from work.
Now @67% and 35°C ( I noticed an temp. increase). Cell standby 47%, Not in use, 41%, android system 9%, screen 3%. uptime 13:35, waketime 1:07.
It connected to H (3g) the last 5-10 minutes or so of surfing. Turned on Wifi when I was finished, to see if I notice any battery decrease.
@14:25, did another 15-20 minutes of surfing, this time on Wifi, now @62%. also was a quick trip via google maps with gps on. battery usage states: Wifi usage 3% and google maps 2% already.. seems they use a lot of battery in a short time.
Wifi is set to turn off after 15 min of inactivety.
TBC....

Read that. Do a teardown and clean everything, you're out of warranty anyways.
Most likley a drop/smudge of beer etc inside short circuiting something and you'll have a slow, but increased battery drain from that.
thanks for giving me a heads up on that!
Not sure if I will take the time to fix it though, I'll have to see how much I miss it when I start using my Dell Streak
@15:35. On my way home from work. Writing using voice recognition on android. Battery level is currently @ 46%. Downloaded several emails, and 1 reply. Now connecting bluetooth for BOL streaming.

Okay now i'm home, after 40 minutes of Bluetooth streaming battery is @36%. Stats are: cell standby 39%, not in use 34%, android system 15%, screen 5%, WiFi 3%, Bluetooth 2%, maps 2%. Times are: 17:07 total, 2:49 awake.

@18:15 Surfing for 15 minutes now over 3g, and battery icon is orange.. level: 27%, awake time is now just over 3 hours.. I think it has held up quite good today, but I have really not used it as much as I normally would. And I also have a suspicion that using less WiFi helps a little on battery. Previous I have used WiFi always on to save 3g usage, but maybe it decreased battery.. anyone with a comment on that?

Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use
none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.
Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?
tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps
well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up
I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.
I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

what do you mean time without signal? and cant flash the build or radio without root(if thats what you meant) im fully charging it now and removed all of my apps...and going to see what happens from there
I've been using mine off and on mostly text, web and speedtests for 4 hours off the charger and my battery is at 91%

For the past 2 nights i have been experiencing this
had 50% power left the night before...
after 6 hours sleep
phone is out of battery @@
Now that aint right, im guessing something is running under locked screen and iono what!!! but i always jump out of any program when im about to sleep too, so it cant be because of that
In the past, i could have standby time for a long period especially after one night. But the past two days when i woke up, it always ran out of battery!! Also when i charged my phone to full life, i sometimes come back after a hour or two to find it dead!!!
This has never happened before and im wondering what could be the cause of it.
In the past i could leave my wifi, bluetooth, location on and it would still last overnight and i wasnt running any program
It cant be because of alphajax right? I mean i did install that two nights ago :\
That is really weird, which phone do you have? I have the hd7 and get 2 days between charges most of the time. Have you tried uninstalling alphajax to see if that helps?
I use a HTC mozart 7
Im gonna try uninstalling a few apps to see if that helps or switch to my secondary battery pack
just to let you know i watch videos before i go to sleep and because its get so hot it drains battery faster, even though i had 50% after I finished watching it went all out in about 8 hours of sleep.
That sounds highly likely, i was playing a game before that, then left it alone for 1 hour, check still had 50% battery, and then went to sleep
woke up with a dead phone
I will confirm that when I have overworked my focus, ie several hours of video and games, the battery can get very hot and if I wait until I get the low power warning, plugging it into my laptop USB can't keep up with the drain.

ok this is ridiculous
in 3 hours i lost 30% power on standby
ITS ON BLOODY STANDBY!!! lol i cant figure out whats causing it. I didnt use the phone for anything at all then put it to charge till 100%. Started counting down time...
If I were you and you dont mind loodsing games aves etc, Id try a hard reset and if that doesnt solve the problem go to LG and ask them to fix it if there may be a fault.
Sorry I cant help further and Goodluck!

I've had this issue as well. This has been going on for months for me. Before NoDo and the pre-update.
Perhaps the battery isn't calibrated properly. Mine shoots down to 50% over the day but sometimes an hour or so after I hit fifty the battery goes critical then dies.
Battery Drain
I have the Samsung Focus. Pre NoDo I could get maybe 18 hrs in standby, and charging from USB on my computer was not happening. I had to plug it into the wall. If I actually used my phone for maps, calls, web or whatever I would get about 10 hr's depending how "how much I used it". This was with EVERYTHING turned off. Bluetooth, location services, feedback, anything and everthing I could disable. After NoDo, I get about 2 days, and now it will charge from my computers USB. Go figure.
All I can guess is there was some sort of corruption in the ROM.
Just a side note, does anybody know what "NoDo" stands for???
Answer: No Donuts
Before the February and March updates, I woke up one day to see my battery had drained from 100% to 0% in about 6 hours of sleep. After recovering from an angry awakening next morning, I paid a lot of attention to how the battery was draining. So I charged up to 100%, went to work on the tube as I always do, and noticed how after about 45 minutes, the battery was down to 50%. That was just some music playback and checking a few mobile websites.
In the end I remembered the day before I had installed two applications, one of them being Lyrics and the other one being a BPM (beats per minute) detector for getting the tempo of a music track. I decided to remove that application and, voilá, the battery drain stopped. I would have uninstalled the Lyrics app but this was already taking me to a decent power usage state, so I stopped there.
If I were you I would check recently installed apps to make sure you don't have a power drainer that's magically working in the background when you put the phone to sleep.
Did you disable feedback in settings. That extended my battery life considerably

I know what your going through, but i found the solution.
Your mobile data is constantly running to check for updates on the game and push notifications. Disable data connection whenever your not using it, and i swear you will see a massive improvement. I have a htc trophy and its notorious for its bad battery. I used to only get 4-6 hours out of it, and now i get 12-14, with WiFi.
That reminded me.... alphajax uses push (although i had disabled it) to notify the user if the other player had made a move...
It all seems LOGICAL that alphajax is the culprit here....
but i also have lyrics, how does that app affect the battery???
Hey guys, I just got the droid incredible 2 and I first had the LG revolution but the 4g and the screen size made the battery drop down quick. I played with it for 20 minutes after it being fully charged, changing settings, and the battery went way down to about 80%. So I exchanged it for the HTC Incredible 2. They told me the batter was way better.
I went to the Verizon store to tell them the batter dowesn't last as long as expected. My Iphone 4 would be on all day, texting, pandora, email and web browsing and I still came home from work with battery left. My droid gets used from 7am to 1pm and its pretty much dead by then. They made me change the background data off, sync only email and weather, and download juice defender.
The batter still dies by 12:30pm after charging all night.
I have read all over people are getting excellent battery usage but I don't really know what to do to get the same. It is not temp rooted. Any ideas? Also, at work, in the building the data coverage is not so good so I usually do nothing but text on it and it still dies by 1pm.
I can't really say how well mine would do on the standard battery because I bought the extended battery immediately after getting the phone. I've been unplugged almost 15 hours and have 38% battery and I have sent/recieved 40-50 txts, 20 mins phone, browsed internet for 30-45 mins, played games around 30 mins, and listened to pandora for around 45 mins.
I would recommend the extended battery, it's $50 at verizon and I haven't even come close to killing it in a day.
Does the extended battery make the phone bigger? I'm thinking it would be thicker on the back. Would it have any drawbacks as to cases and stuff like that?
I'm not sure why mine is so bad, prolly because I am in a secure building and signal doesn't get through constantly. I'm surprised, I thought my iphone had bad battery.
the extended battery does have a thicker back. and yes, there are currently no cases for it, so there would be an issue there if having a case is very important.
as to your current battery, if your in a biulding with bad signal, that will most defintiely affect your battery life as your phone will have to use more battery to try to find a good signal. additionally though, the phone battery does seem to improve after about a week of charge/discharge cycles. not sure why this is, but i have seen it on my phone and seen many other report the same.
The battery sticks out a little more than 1/8th of an inch I would say. However, IMHO it protects the camera lens and flash lens from getting broken and I never really like using a case anyways.
I have amazing battery i charge it to 100 percent unplugged after then go to school texting 100-200 average everyday internet music by the time i get 3:00 i still have 80-70% and i'm 13 so imagine how much i use it and it still stays at that percentage
Having a phone in a building (or anywhere) the signal is weak is a drain on your battery. If your iPhone was with AT&T the signal may have been stronger where you work than with Verizon and may have therefore contributed to better battery life.
Also, if you didn't FULLY charge your DInc2 and FULLY discharge it right when you got it, you should really do a factory reset and immediately do the following:
Charge the phone for at least 8hrs with the power off, unplug for a few minutes, plug it back in. The light should only remain red for 10-20 seconds before turning green, otherwise this unplug-plug part should be repeated a few more times always letting it remain on "green" for an hour before unplugging an plugging back in.
THEN power up and use the phone until it shuts itself off because the battery is drained. Let it sit for a few minutes, and turn it on again. It should sut itself off again pretty quick. Let it sit, turn on again. Do this until it wont power up at all after sitting untouched for a few minutes and your battery is then fully discharged.
Now you can plug it in and start the charge part of the cycle as lined out earlier. Once the light turns green 10-20 sec after plugging it in again you have completed one "cycle".
This may sound excessive, but I'm kind of a nut about this kind of thing.
I didn't do anything special when I got my I2, am a realtively heavy user, and have an all day battery life. I'm pretty careless with my features being left on.
If you can't get it to last all day, either you are a much heavier user than I am or you do, in fact, either have a battery problem, or a battery calibration problem. You shouldn't need to calibrate the battery algorithms, but I guess it doesn't hurt to try.
I wouldn't say I am a heavy user. I normally text while I am at work and check facebook a few times. I also listen to pandora most times. I work for Vanguard and most people here have Verizon I believe. I was told when I switched from AT&T that signal should not be a problem where I am at. My Iphone 4 would get used much more and it too would have signal problems as well until I turned 3g off but it would last way longer than the droid.
I guess I can try the factory reset and full charge cycle this weekend but I'm not sure what Verizon can do for me either so it may just stay like this
this is bump charging no? (well the part about how to charge it). i spoke to am htc rep that said that bump charging will significantly decrease the lifespan of your battery life and therefore is highly not recommended.

I just got mine on Sunday, but even yesterday I was texting and surfing a fair amount yesterday and went to bed with the phone at 61%...
I am sort of amazed, I think Verizon has taken the underclocking thing and put it to work on the official release... at one point I turned off the screen for what amounted to an hour and when i turned it back on it was still the same battery level.

if your comparing battery life on the dinc2 with 3G on versus the iphone with 3G off there will also be a pretty big difference. if your tuirn off 3G on your dinc2, i would imagine battery life will be similar or better than your iphone had with 3G off also.

No I was comparing the Inc 2 to the Iphone with 3G on. My iphone would also last longer if I turned 3g off and just used Edge or whatever it is called. I don't think I can do this with the droid until it is rooted or download an app to do this.
I turned off juice defender and we will see how it goes today. I don't really like apps running in the background and it was turning off data eacht ime the screen locked.
I think the biggest difference is the verizon signal. The battery on this phone is amazing for an android device. While it is still nowhere near iphone 4 status as far as battery, it shouldn't drain like that. Have them either swap you a battery or the phone itself.
I'm a relatively heavy user. Especially with voice calls and I can go a day and a half easy.
But I also run launched pro with only a couple of widgets. To me sense is a battery hog.

What would I do to go about swapping out the battery or the phone itself? Should I go back to the same verizon store? Or call them on the support line and try to get a battery or new phone that way? I have no clue why it is draining like that either, the signal can't be that bad, I literally had the same signal with AT&T in these buildings.
Well, lets be honest, one of the things Apple really puts a lot of time and effort into in their development is long battery life. It wouldn't surprise me to see the iphone outlasting most Android devices.
In any case...
While I don't need to, I do charge my phone while at the office. If you have a desk job then I don't see how this would be problematic. My work day usage includes 2 hours of bluetooth streaming (in my car to the stereo), media playback (music/podcast), and mapping with gps and 3g data (this drains my battery pretty quickly, but that's relative...it's about 15% per hour). Outside of that, my battery drain is quite low.
I only started charging at the office because I like to keep my battery as full as possible in case of extended emergency that requires being away from a charging source. It's that whole boy scout be prepared mentality I have. Besides, if you have the opportunity to charge, why not? It seems to charge pretty quick anyway.
I can charge at the office, but normally I forget the cord at home. Not a problem to buy another one but still. I was just concerned because I hear people getting 15 some hours on one charge and as of right now, my battery is below 50% since I just got back from lunch.

take it back to the store, and if that doesn't work then call. but the store would probably be a better bet as they can give you a new phone or new battery there whereas the phone support, you'd have to wait for the shipment.
Seems as if they were not able to help in store the first time. Rather than have someone check it out, they had someone come over and tell me I should turn off all the sync and data features. So I did do that, but then why did I get a smartphone?
It's possible you have an app that is not allowing the device to sleep. If it can't sleep, it will drain the battery much faster. You might get 8 to 12 hours awake yet idle.
Are you using many third party apps? If so, have you considered going through them, removing them one at a time, until you find the battery doesn't drain so fast anymore?
If you go to About phone in settings, then Battery, the last item will show awake time. This should be much lower than your Up time.
Had my 900 about a week now, and in the first few days the battery life was looking good, lasting nearly two days with lots of texts, emailing, a few pictures taken and lots of talk time.
Then a couple of days ago it suddenly got worse. Started losing about 4% per hour. I charged it fully last night and then this morning nine hours later there was only 60% remaining.
I decided to try and find out what was happening. Found the diagnostics app and the battery drain was showing around 164mA. I don't have anything running that could be using so much power, so I wondered if I was suddenly getting a poor 3G signal and the phone was using a lot of power trying to receive it. So I put it into flight mode. Still around 164mA.
Finally I powered the phone off and then back on. Now it srttled down to around 95mA.
So what was running that was using so much power, that got switched off when the phone powered off? Could it be the GPS? I did fire up Nokia Drive and Nokia Maps the other day to play around with them. Could it be that the phone forgets to turn the GPS off when the apps that use it aren't running?

Not sure forgets is the right answer, but you may want to look at the Background tasks and see what is running when it shouldn't.
I know when I add a new app or 2...sometimes I get myself in a position where the battery drain becomes excessive. I usually just unistall the app. You've probably read a few of the battery threads here. If not, take a look. Lots of good conversation about ...well....lots of things....
For me, the biggest drain is Wordament....and its ads....I'll wipe out my battery in an hour playing that thing....
Just finished a series of tests for Background Tasks in my L900 (full article on Mobility Digest). 8 Background Tasks running burns 0.5% per hour, or 8% in a 16 hour day. Tasks included: USA Today, Fox News, Weather Channel, Urban Dictionary, Mehdoh, Network Dashboard, Clever-To-Do and Battery Meter (homebrew app that actually runs every 10 minutes vs. 30 minutes, or longer).
Except for short spikes, my phone always hovers in the 95 to 125 mA range. Data signal is still the biggest battery demon while phone is asleep. Screen while phone is awake.

Overnight my phone seems to have used less than 1% per hour, that's with wifi on but not connected to any network. Perhaps I'll see what it does with wifi off.
I'd still like to know what it was that was draining the battery until yesterday when I power cycled it. I only had the App highlighter app and the Weather Channel app running in background, and I've since disabled the App Highlighter. But they weren't using 4% of the juice per hour. I didn't have bluetooth on.
I guess if anyone is seeing a high battery drain the simple answer is to try power cycling your phone first and see if that stops it.

Just finished a series of tests for Background Tasks in my L900 (full article on Mobility Digest). 8 Background Tasks running burns 0.5% per hour, or 8% in a 16 hour day. Tasks included: USA Today, Fox News, Weather Channel, Urban Dictionary, Mehdoh, Network Dashboard, Clever-To-Do and Battery Meter (homebrew app that actually runs every 10 minutes vs. 30 minutes, or longer).

Cool! I'd love to see a wifi vs cellular data battery benchmark.
Well that would be hard for background activities as WiFi goes to sleep at power off.
I did try to use LTE only for a couple days, but AT&T did not start reporting my daily data usage on my monthly anniversary data. I wanted to see how much data I was using over a typical week with LTE only. On can tell you in those two days, LTE was burning 20-30% (13% per hour on WiFi / 17-18% per hour over LTE) more power per hour when the screen was on and I was browsing or using Board Express. A more comprehensive teat will follow though.

The above somewhat proves how cellular data can often be a big battery drain comparable to abundant wifi at home or other common places. Looking forward to ur tests.
Well the battery drain problem came back yesterday.
The phone has done pretty well however, with very light use (one short call, a few texts, checking FB, checking the weather and not much else) the battery is at 24% after 48 hours. Overnight it went through about 8% in nine hours.
However, yesterday evening I noticed that the battery was losing 4% - 5% per hour again. By yesterday morning it was at 70% after 24 hours. After another 9 hours it was down to 43%. That's having made no calls, only a couple of texts, and very little else. At 9.30pm I checked the diagnostics app and battery drain was over 200mA. There was no obvious reason why it would be so high. So I powered the phone off and back on again, and sure enough, battery drain settled back down to between 90 and 110 mA, and as I said, overnight the battery lost less than 1% charge per hour.
The only background task I have enabled is the Weather Channel app. I'm going to let the battery run right down, recharge it, uninstall this app, and then see if I can repeat this pattern (if people will hold off from calling me!) If it's not this app then there must be something else, something in the firmware that goes haywire after a certain time and starts using lots of power.
I note that some people have observed that the battery starts to drain quicker after a while. I'd be interested to know if anyone can repeat the same pattern I'm seeing.
Just an FYI,
My 1st sprint GSIII was fine for the 1st month. I could get upto 3 1/2 days of battery with very light usage (mostly standby time). NOt sure what caused what happened next but the phone became extremely warm and the battery life dropped to approx. 2 hours. The phone was very warm even while off for hours!! And it obviously got even hotter while on the charger. The only way to get the phone to return to room temp was to pull the battery and leave it out for a few hours. Turning wifi/data/sync/GPS etc. off did nothing. The odd thing was, the battery was a normal temp. The heat came from the lower part of the phone (where the processor is). It also gave incorrect battery readings. While plugged in it would read "100%" and "charging" the LED stayed red, never turning green. I also could pull the battery and put it right back in and it would read 20-30 % difference VS. when I took it out.
The phone was swapped at a sprint store covered by insurance.
The only thing i did differently usage wise was link the phone to my dropbox account. It seemed to sync normally so i can't confirm dropbox caused the issue. I just can't figure out what the phone was "doing" while it was off. Just thought i'd share the story with the phone. The new 1 is running fine.
I found this today. Appears to be helpful with heating up and improved battery life.

Let me know what you think.

This doesn't sound good at all. My cousin's GII on AT&T did something similar to this. The phone would be completely turned off and it would vibrate every 10 minutes. Even pulling out the battery and reinstering it made it automatically turn back on and vibrate again and again.
Hopefully this is an isolated issue what you are talking about.

What kind of signal are you getting?
Mine was like what you descrbed for a couple days(almost no signal at home) and I was getting ready to return it but didnt have time because I was leaving for Vegas. Long story short when I got to Vegas I upated profile and PRL and havent had a problem since. Maybe the towers in your area are under constrction.

My phone has gotten hot ever since I got it, but it will cool down when I stop using it. I am getting horrible battery life even witha 4300 mah battery. today it wouldnt even last 11 hours. It had 3 hours total usage time on it. I am now trying another 4300 mah battery to see if that is the problem or if its the phone. my reg battery wont last me very long either. I am also using juice defender free version and advanced task killer plus the built in task killer and I cannot get my phone to last very long. With my orig Evo I had the sprint extended battery (2500? mah) and it last me til bedtime with 50% left.
The only time this happened to me was when an badly behaving app "ran away". I would get really bad battery usage at the same time. I could cure it by clearing ram, which shut down all the running apps. Since this hasn't happened to me in a while I'm guessing that whatever app was doing that to my phone has been updated to fix the bug.
My issue was very odd. My phone was normal lasting up to 3 days with very light usage. It would sit for hours at "room temp"..the only thing i did differently was link it to my dropbox accnt. It seemed to sync ok..it was shortly after that i noticed the phone was very warm towards the lower 1/3 of the phone. I thought maybe there was something running or taxing the processor. So after working on it for a few days(turning everything off i.e. wifi/gps/data/sync/etc etc.) the battery got worse and worse. I then unlinked dropbox, stopped all running apps and let the phone sit in airplane mode over night. Still no joy. So i turned the phone off and let it sit for about 6 hours. It was still "very warm" while off!! At that point I pulled the battery for about 2 hours and the phone returned to normal temp. What could the phone be doing while turned off for hours?
The phone was stock and updated. I use an airrave so i dont have signal issues. The processor seemed to be running at full load even while the phone was off. The battery life went from around 3 days to not even 2 hours. The phone did seem to have the known "cell standby" issue(where the counter is reporting an incorrect usage %). While charging, the phone was even hotter to the point of me thinking it would burst. Oddly enough, the battery was at a normal temp. It was no where near the temp of the bottom of the phone(where the processor is located).The new GS3 is running normally so far. The tech at the sprint store couldnt figure the old 1 out so they just replaced it(insurance/no charge).
