I was going to post this in response to a fast draining battery post, but think this is a little more important to others that might find it interesting. I noticed on Tuesday I was at home on the couch and I had a few apps running like normal and my battery was around 80 or so %, but nothing I would ever consider CPU or even GPU intensive. I think email and maybe web browser. I decided to check the weather using the "Weather and News App" I don't have wifi on and I have location via wireless turned off so I manually entered in my location. I put the phone down and I swear 30 minutes later my phone felt really warm and I went from 80 down to around 50 fast.
Yesterday I was out with the wife shopping and I had around 90%. I fired up shopsavvy because she was interested in some coffee maker and of course I had GPS off and wireless location off because all I wanted was a web price. I did my scan and put my phone in my pocket. An hour later I noticed my phone felt a bit warm and it went from 90 down to 36.
I don't know if its a combination of other things I had running, wireless and GPS off and the vibrant was working hard to try and connect or what. It was just an observation I had and basically I just shut down and turned my vibrant back on. Battery was still low and the warm area high up on the phone cooled down. I thought it was the battery at first, but since the battery is on the lower half of the phone it had to be something else.
I have had similar suspicions in the last 10 days or so but haven't narrowed it down. If you figure something out please post.

Same heat related battery drain
Same exact issue here. Phone was at 100% at noon, I was out in the hot sun with the phone in my pocket from that point on and the phone was dead by 5pm. Any help is appreciated as I too thought it was the battery.
My phone warms up a little when I use either the GPU (gaming) or Cellular radios (continious surfing or tethering). The battery goes down because the connections or GPU is sucking juice.
Same things with my phone, battery simply drains even when phone is off in m pocket. It always feels warm and obviously something is sucking the juice out of it.
Yea, battery is the one and only thing I hate with a passion with my phone atm. Can only hope that it's just an issue that can and will be fixed via software on 2.2 :/
I noticed that my sd card is the warmest part of the back of the phone when it's in use. Have a class 4 pny 8gb from walmart
I had to uninstall shopsavvy bacause the phone was getting really warm and was draining battery very quickly.
I don't think it's shopsavvy, but maybe a faulty gps driver or the whole location awareness system.

I just had a couple of longish calls in a short period. Both averaged about 30 minutes or so.
The phone is HOT. It is hot on the screen and battery side. This is not the first time the phone as started to get warm after long use.
This has never happened on my Raphael. I had it happen the other day while I was using the GPS a lot too. This seems like a very bad thing to me as heat will destroy the battery and possibly chips.
Hmmm....supposedly from the HTC site:
Why does the phone heat up when I’m charging the battery or when I’m making long duration calls? more
It is normal for the device to heat up during charging. After charging, it will return to its normal temperature. It is normal for the device to heat up when you are using the same function for a long time, such as making long duration calls or recording a long video clip. Please rest assured that all HTC devices are factory tested before released. Was this helpful? Yes | No
(I say supposedly because only way to get it was using Google Cache...the page didn't pull up from the link.)
But this isn't 'warm' like I would expect from a battery...this feels hot, like when I tell someone not to put laptop on their lap because blocks vents...and then have them put hand on their laptop. That kind of hot.
Install System info widget and check the temperature of your battery, should be at 98F - 106F
I've had mine get too hot a few times. I'm assuming that's what this means, but when the phone is hot, I see the led indicator light alternate flash between green and Orange. I've taken out the battery and let it cool down and then everything was normal again. I'm beginning to agree with other people that I don't like this phone. I never had this problem, or any problem, with my Samsung moment. If this crap continues with this phone, I am giving the Samsung epic some serious thought. People have ranted and raved HTC phones. The Evo being my first one, I'm not very impressed with it once I played with it for awhile. Yeah, the specs looked impressive on paper but in real life, I don't care too much for it. I guess I will wait and see what happens.

Any idea why the phone would get warm when screen is off and you have no background apps running? I get this at work amd im sure its not caused by signal searching Im outside all night
My phone shut down from heat today.
I got into my car, turned on gps and bluetooth, put the phone into the mount, and started navigation. Sure enough, the thing shut down in about a min. The car and the mount were kinda hot too.
I had to take off the silicone case and point 1 air vent at the phone, to get the temperature to a pretty cool 31C (with charging at the same time).
On its own, I haven't seen the battery heat up, especially when the screen is off.
Perhaps that batter is defective, or you have a rogue process that's running the battery down.
How fast does your battery drain when it heats up, and normally?
The normal speed for draining the battery with the screen off is about 1% per 1 hour.
Covers, cases, holsters, in your pocket, being in a hot car (even not in direct sunlight), etc. Pretty much anything that can keep the heat from escaping the phone or add to the phone's temperature.
I hope cyanogen can be a miracle maker with the custom rom he's making, because this phone's quirks are getting on my nerves. Yeah, it's past the 30 day return deadline.

Which other phone can run 1Ghz processors and not overheat under full load and inside a case?
I think common sense tells me I should have expected that.
I get pretty good battery life from my evo. 20 hours of moderate/high usage took me to 30-40% but I work in a pretty well air-conditioned ambulance and drive around with my phone in my lap most of the time or in my pocket on occasion and when I pick it up sometimes the screen and back cover are warm. I look at battery temp and its like 32-36 degree celsius idling like that
Edit: phones naked btw no screen protector or case for now
After a couple hectic days of ebook reading and killing my battery my phone was getting hot like really randomly and when I had the screen on for like 10 mins or more, or when I charged it or pretty much if I even looked at it wrong! On a side note I have it in the body glove case from Sprint. Also my battery life was horrible. I was going down to like 30% in like 7 hour of practically no use.
Now I was running completely stock and unrooted( I hadn't felt the need to root yet) My solution was I rooted, installed DC rom then and I believe this is what fixed it cleared my battery stats from the recovery menu. Bam my phone hasn't even gotten warm since. Also it's been a week since I did this, and I'm getting crazy battery life now( like I'm down to 70-80% in 7 hours now with light use)
Hi I'm new to xda, and from the looks of things everybody seems very helpful
I was just wondering if anyone else has been having this issue
Upon regular use and normal brightness I notice the temp of my phone to be around 98 degrees but when using highest brightness levels its around 120 degrees!
Another thing is that when my battery is charged at 100%, once I remove the charger it immediately drops down to 97%
Has this been happening to any of you guys? Have to you found a solution for this?
Also I've been using battery life version 1.3 from the app store if that helps
Thanks in advance guys

Mine only gets really hot (temp > 100° F) if I am charging it and playing a game or watching a video at the same time.
Otherwise it stays at a reasonable level all day. Currently charging via USB; temp is 91.4° F.
Also, haven't seen mine immediately drop to 97% after unplugging. It usually takes a little while before my battery widget shows any drop in charge.

My Vibrant can get pretty warm but it's no worse than the CLIQ I used to cook my dinners on.
Haven't noticed
Mine gets really warm when I play Sims for an extended time.
Mine gets hot when the GPS is running. The heat doesn't come from the battery area, though, but from the top part of the phone - around the camera.
What happens is my screen gets blazing hot almost like a light bulb, the back however does not get as hot as the screen, I'm wondering if this just is a hardware issue and if I should swap it out or not

bingo - I have noticed the same with GPS on.
compared to my g1, this phone is "Warm" at best. Damn thing used to burn my lap with gps+wifi.
I have noticed the same thing. Mine gets really hot when it syncs non stop. I had to perform a factory reset and for now my phone is fine.
I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I got 25 hours of a charge the other day. Had to grab a screen shot real quick before it **** down. Might frame it. On stock dk28 with moderate use, lots of pics...it was on christmas so it was prety well used, trying to escape conversations with in laws.

I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??
Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.
I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!
I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.
ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.
Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.
DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.
I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.
I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

I noticed Yahoo mail and Craigs list apps I downloaded from the market have a memory/cpu leak that kills your phone super fast.

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.
Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.

I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.
def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
so far this thing is a golden brick to me
Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

Its under # 13 on my 3rd post.
getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.
Sent from my cm7 Evo 4G!
Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.
Sent from my cm7 Evo 4G!
Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.
Im a wireless technician and when I need to climb a tower I tend to leave my phones in the truck (work phone is a S2). After a couple of hours of the phones being in sub zero temperatures, the Atrix loses about 60 to 80 percent of battery. Well, thats what the OS is telling me. It will continue to work throughout the day at 1 percent. If I charge it from that point forward it wont charge past 70 to 90 percent. Depending on how long I used it at 1 percent. Only way to fix it is remove the batter after it has been in the charger all night and put it back on once the question mark is there. And I need to do this almost every night. If I leave the phone for 30 minutes it might drop 10 to 20 percent. But just enough to mess up.
This doesnt happen with the S2. It does drain faster but it is not noticeable. Anyone else notice this? Oh and my Atrix messes up big time in the humidity so I have something to look forward to this summer.. I doubt the phone will last long enough to get ICS.
And something else I noticed. After I pick up the phone after it has been in the cold for a couple hours I will check SetCPU to see what my cpu temperature is at. I have never seen it below 18 C. Makes me wonder how accurate it actually is. If the phone is room temperature at idle, my CPU temp will be 39C. I bet it is actually only at 25 to 30 C.
I first saw this behavior when I took my Atrix camping in December. The phone was at 95% when I turned it off at night, and in the morning when I turned it on, it was at 40%. Another guy camping with us had an iPhone with a similar drop, but I don't know what his percentages were.
This weekend I was in Utah skiing and fully experienced what you are talking about...the phone was on the charger all night and it would only go to 70%. I pulled the battery and after the restart it was at 99%. This was in my heated hotel room and not outside.
I think the cold weather in general causes batteries to go crazy. Have a read:
http://batteryuniversity.com/learn/article/discharging_at_high_and_low_temperatures
I have the exact same thing happen to me as the OP and it has been happening for a long time even after i got a refurbished atrix so it is definatly something to do with the battery and not the phone itself. Damn cold Canadian winters

Hey we can't complain. Its very mild, well here anyways. And I love wasaga. Best may long weekend place to go!
And as far as the issue.. I have noticed it with my iPhone but once charged it was always go to 100 percent. Sucks that ours really messes up.
There is a wealth of information about lithium ion batteries if you look for it. They perform better in colder temperatures. They self-discharge slower in colder temperatures. Their lifecycle degrades slower in cold temperatures.The only real drawback is that the need to be warm to pass full current, so an extremely cold battery might not power your device properly until it warms slightly. If you let your battery discharge all the time it will severely decrease it's lifecycle, as lithium ion does not cope well with this.
NASA requires that their lithium ion batteries perform to -80C.
Remember that the batteries also have protection circuitry for safety. This may be set up in the Atrix batteries to discharge rapidly under certain circumstances.
I believe you can get a rapid discharge though if you go from an extreme cold temperature to a very warm temperature quickly, which could be the case if a phone sits in a truck all day at sub-zero temps, then you jump in, start it up, and start cranking the heat.

Never had that happen.
Had the temp down to 12 C on the phone.
It did get a little hot during the summer months.

Hey we can't complain. Its very mild, well here anyways. And I love wasaga. Best may long weekend place to go!
And as far as the issue.. I have noticed it with my iPhone but once charged it was always go to 100 percent. Sucks that ours really messes up.

Living here you come to know that May long weekend is the WORST time of year because the majority of tourists are jerks! Fun to watch them get arrested though Right now its cold as hell. And yea it kinda of sucks, no matter what i do i can't make it read 100% it just goes up to that on its own sometimes. One time i had my battery last 3 hours sitting at 1%.

I've had my atrix shut off on me while skiing a few times. Get home and plug it in and it has plenty of juice...just cant push out enough current to power the phone properly.
My phone sits in my work truck all day (since its not intrinsically safe) and even when the temp is well below zero it never fails to come off the vehicle dock without a full charge just that sometimes it thinks 40% or 70% is a full charge fixed it pretty much the same way as you guys described. Other than that in low temps the touch screen responsiveness is sometimes an issue and ocassionally the external sd card wont show up until it warms up. but overall a reliable phone considering the abuse it takes. wonderfull build quality from motorola as usual.
However... I think heat is a bigger issue as I managed to melt my first vehicle dock this summer when it hit 34C in Calgary. The suction cup and part of the stem remained on the windshield but luckly the phone fell to the floor in the shade.
Really surprised I haven't seen any pix of melted atrix on the internet unlike the S2 & Iphone4
