I have the T8585 HD2, recently ive been having troubles with the battery...
I was getting intermittent battery drain for no apparent reason, the back of the phone would get very hot. Searching I found that this had something to do with the SD card not being formatted properly, did this and havent had this same issue since.
Last night I charged the phone while on my PC, was approximately 80%. I wake up this morning and the phone is dead, wont turn on. So i plug it in to charge again and then it starts to do the soft reset loop thing, I just left it go for about 6 or 7 loops and then it seemed to settle. I look at the battery capacity and its 0%.
This explains why it was dead, but why the hell is the battery draining to nothing over night? I did not notice it getting hot last night and it was dead cold this morning. Battery terminals are not bent as some others have suggested as a cause for this.
I really like the HD2 but this battery thing on top of the poor capacity for the this type of phone is really starting to disappoint.
I have not messed with ROMs yet, so its running the following that i got with the phone...
ROM 1.66.707.1 (76641) WWE
Radio 2.06.51.07
Any ideas on this would be helpful!!
Same phone, same software
I have exactly same phone & software, I upgraded rom to this 1. But have had no problems with phone at all. Few soft resets at 1st, but then started deleteing messages, shutting down programs in background, no problems since. Hope you get figured out,,
I'm having the exact same problem. I've had the phone since November and, although the battery doesn't last like it used to, since about 2 days ago the phone has gone haywire!
I haven't installed any new apps or used the phone any differently than usual but, after getting readings of between 15 - 20mA in standby (with Battery Guard) I'm getting on average 490mA now in standby! Crazy! The back of the phone is getting so hot that I'm actually worried that it might do the phone damage and, like the OP, I'll go to bed with a full charge and wake up with the phone so dead that I have to pull the battery before I can start to recharge.
I've removed some of the PDF files and other things that might be causing slowdown etc due to but there is definitely a problem. Does anyone have any ideas of what kind of things I should look for that could be causing this before I contact the insurance guys for a replacement?
Thanks in advance
Im having a similar problem with my HTC raphael with WiMo 6.5 Roms didnt tried if the problem exists in 6.1.
My phone is fine today, was 100% last night, 95% this morning. Im starting to think this is a software issue not hardware due to the randomness....

funny you put it this way.... its actually the other way around.... nevertheless i understand what u mean (off-topic, just couldn't resist ;-) )
when the power usage jumps from 20ma to 490ma and gets very hot the battery has started to fail - don't be surprised their qualty is hit or miss. I'm on the T8585 HD2 (1.66 rom) since November and a few weeks ago the battery would get hot in standby and battery life dropped by half. I popped in a spare battery and problem instantly went away. I've since bought a 1,300 mha battery from Mugen, phone runs great again.
Hi. Had a similar thing with the battery drain, but the last few night I have put the phone on charge as normal and in the morning I have Nealy dropped the phone because of how hot the back was. Any ideas?
Happened again today, fully charged last night, 0% this morning. Very unhappy about this, this is a serious reliability issue that a $700 phone shouldn't have.
I would suggest checking your task managers processes, I had a process - Filesys.exe that was using 98% of my processor for long periods of time and absolutely eating battery life.
Yeah i have installed battlog to see if that will shed any light on the problem...
Did u try hard-resetting ur device?
no, im trying to avoid that at this stage, I want to find the source of the problem.
Had the same issue. Phone worked very well for a few months and then this battery drain + overheating issue started all of a sudden. Tried hard reset, disabled 3g and problem continued. Finally, got my phone replaced with great difficulty and problem solved!
Anyway, check the signal strength. One of the issues could be the phone trying to connect repeatedly when the signal is weak. You can also try to disable data connections to see if that causes the problem (Disable all autoupdates like email, twitter, weather and so on).
I noticed this a couple of days ago: I was in a place with no 3g nor wifi so I decided to switch O7 off. In the evening I switched it on and battery was empty.
I tried again yesterday with the same results. What"s using this phone while it's off?
Are you sure it is actually flat?
My battery has a problem, if i turn the phone off and then on it will show that my battery is empty and want to turn on battery saver. If i keep turning it off and on and mess with the battery contacts it reads properly.
Just a thought....
This is because the battery is cold, let it warm up and it will display the correct level

This happens after being on for days, it's not to do with temperature.

It also happens to me. Not usually but once every 1/2 weeks. I've been looking for a solution and the only one i found is switching off and on again until the battery level is ok. However i have to say that this has been happening since i installed 7740 update, so maybe the problem is that.
not actually drains...
I think the battery did not darain.
It is just the battery level is not displayed correctly; I had the same (or similar) problem. I switched off the phone while the battery was at 80% and the next morning when I switched it on I got the message "the battery is low..." and the wrong battery level displayed.
I kept it on for hours and it worked nicely; I noticed the battery info displayed 1% of residual charge and 7 hours of expected workng time...something weird
Suddenly after hours of usage the battery icon started to work properly.

Exactly the same as me. I'm on my 2nd Omnia handset now (warranty replacement) and this one does the same so I assume it's the battery that's faulty.
If you leave it on long enough the battery meter slowly increases over time until it reaches the true value.
Just installed 8107 upgrade via cab; let's see if problem have been noticed before and solved now
I noticed this problem also. After the mangu upgrade it is not there any more.
For me it seems that th eproblem laid in the firmware..
funny, I'm not the unique
Today I've tried to make an hard reset to see if the problem would have been solved. I'm on Mango 7740, tonight I'll try to switch off the mobile phone after charging.

I did a hard reset, OS update and then a handset replacement and the problem is still there.
I'm convinced it's a fault with the actual battery.
Ok, I yesterday evening I switched of the smartphone for some hours... Then I turned it on and I saw the"popup" which told me the battery was low.
I left the device on, with 3g on for all the night and this morning I found the battery level as it was before yesterday evening
I confirm the battery do not drains when the smartphone is turned off!

As I already said, this is because the battery gets cold when you switch off your phone, and it then appear drained. After heating up again it will recover it's charge.
"Show low low battery logo" Nexus 7 thinks battery is dead even when fully charged!
I have already got a replacement on order from the Play Store but since I haven't seen any reports on this after plenty of searching I figured I'd describe the issue.
My 16gb Nexus 7 worked pretty much flawlessly for the first several days of pretty light use minus very minimal flicker on occasion. As of two days ago the unit is basically unusable as it randomly but excessively decides that the battery is dead even though it is fully charged. The first several times this happened I wasn't paying attention and I thought it just shut off by itself, but then I started to watch it more closely but it also started happening more and more. As of this morning it will not stay on more than 5 minutes before it audibly notifies a low battery with the messages "Connect Charger" and "Powering down". Sometimes it will give two options "Battery" and "OK" but I was never able to actually get the buttons to respond because it would already be shutting down. Other times it will just show the connect charger and powering down messages with no buttons which is strange, but in either case the device shuts down.
Once I started troubleshooting I figured out a little more information.
Watching the lock screen while it is charging I will see it go from it's (I think) correct charge percent to 0% randomly.
While not charging it will either show a red battery indicator in the notification area or just an empty battery when it decides to shut down
Sometimes it will boot right up and be back up to regular charge level (of course just to shut down again within a few minutes)
Other times it will not boot up and I noticed the error message (almost like a debug prompt mistakenly left in the code) in the upper left corner "Show low low battery logo" + some strange symbol like when you get 100 1-Ups in Super Mario Brothers . Yes the message has the word "low" twice - I guess this is lower than standard low!
Anyway, kinda bummed but since I have not seen any other report of this particular issue I'm hopeful that the replacement will not have the same problem. I'm just hoping I don't get a unit that has some of the other problems being reported so I'm crossing my fingers.
Mine started doing the same this morning

This sounds pretty similar to my problem from another thread. Every time it hits 25% while discharging it dies. Normally I'd say it's just a software calibration issue and fixable by wiping battery stats, but I've wiped several times at 100% and run down to 25% and it still dies.
Do you find that you still get a normal amount of battery life before it dies? It'd help to establish whether this is the battery misreporting, or actually not discharging properly.
* Strangely this time after my N7 had died at 25% I turned it on and it's at 0% battery. It's been charging for ~15min and it still says 0%... When you all first got the device, did you let it run to 0%, or did you charge it right away?
** And now, after almost an hour, it's at 1%. Seems to be charging, but brutally slowly (and I'm using the bundled charger, not PC USB).

Yours sounds like a similar but different issue. My N7 dies regardless of how much charge it has. It can have 100% charge and within 5 minutes it will report 0% charge and die. Then when I can get it to boot again it will be back up to 99% charge again. I can't get more than 10 minutes of use before it dies regardless of how much charge it truly has.

I'm starting to have this same issue, however mine goes at about 19%. Just turns off. I have also seen the show low battery in white text thing. I have tried calibrating by fully charging then deleting batterystats.bin from data/system and letting it decharge and it still died around there, I'm recharging again to 100 to see what happens this next time I let it go... thought mine was issue free than this happens
Well in case anyone else runs into this, I have no idea what caused this or how I got out of it thinking it was dead at 20%. I tried deleting the stats, reflashed stock and then CM10 and back again, tried a different kernel, and still died at 20 and gave me the "low low battery logo".
I just took it into Gamestop where I got it and started the process for an exchange, so I have another one coming now. Go figure when I got home I plugged it back in, and now this time just like omnikai said instead of being at 20% it was at 0 when I turned it on. Been a while and now and seems to be charging normally so hopefully it will decharge fine.. either way really weird only problem I've had with mine so far
** Just wanted to edit and say its now decharging normally dont know what caused it to spazz out or fix it one of those ghost in the machine android moments

Replacement N7 seems to be fine thusfar...
Apparently, somebody in StackExchange is having the same issue as well:
http://android.stackexchange.com/questions/27222/nexus-7-system-error-show-low-battery-logo
if anyone else gets this, try disconnecting the battery and then re connect and see if that fixes it. i had same type of issue on viewsonic g-tab and that was the required fix.
Mine did it at 10%, calibrated the battery and im getting truly awesome battery life 2 full days without a charge

While this reply is late to the game, it needs to be pointed out that such apps are 100% snake oil and do not calibrate the battery. They are based upon gross misinformation and any dev that tells you that clearing batterystats.bin has any effect on battery life or reported battery charge clearly doesn't know how Android works.

Have you fixed this yet cos mine does the same?
I had been having the same problems that everyone described: would suddenly die at 25% and wouldn't turn back on unless I gave it a charge for a bit and then held the power button down for a while.
For the last 2 weeks, I've been charging it only with the stock charger and that seems to have fixed it. Previously I would charge with any charger I had around.
Not sure if it's a permanent fix but it's working now (I've taken it down to 4% before charging it back up).

I only use the stock charger on mine but after this happened so often I tried another one and battery charged OK but then kept blipping from say 50% to 54%, went bed with it at 49% and this morning dead again. Charged it again today on stock charger and waiting to see what happens.
Sorry all for this bump.
I just got this same issue tonight on stock, unrooted nexus 7 16gb and I only use the stock charger, I let it die through battery and then when I charged it amend turned it on, all these problems happened.
One symptom that hasn't been mentioned is that the clock is set back to January 1st 1am.
I managed to get it to start without turning off by holding the power button until the Google logo showed twice, at the moment it's on but charging.
Hope this doesn't become a problem again in the future.

I recently started having the same problem with my 2 month old rooted Nexus 7 (wifi only) . It was dying at about 19% - 23% charge . Tried doing the battery recallibration at 100% charge, even wiped the device clean and flashed the Jellybean 4.2 factory image but it didn't work.
I talked with the ASUS service center guys to get it fixed, and created a sort of guest user so that I won't have to disconnect my accounts. After that my problem seems to have been fixed. I discharged it to about 4% and then put it to charge, it's charging properly now so I am hoping the problem has been fixed.
I am not sure whether this would work for everybody, but I guess it's worth a try.
Hi
I have recently started having a problem with what I presume to be the battery of my Nexus 4. It seems to have started suddenly about a week ago, though was working absolutely fine before. I don't think it was due to any specific app having been installed. I have also done a factory reset on it, but that didn't solve the problem.
Basically, the battery will discharge to about 75%. The phone will then suddenly switch off; turning the phone back on, it simply shows the battery to be fully depleted and switches off. If I plug it into a power source, the phone turns back on and begins charging, from 0%, though seems to suddenly fully charge it within about half an hour.
My phone has not been rooted.
I would really appreciate any help/advice on this issue as it is incredibly frustrating having to have my phone almost permanently on charge.
I have attached two screenshots of the battery usage graph.
Thanks!

If you are on stock, try flashing the stock image(4.2 or 4.3 up to you) there's plenty of threads on here thatll guide you thro the process.
I've had the same issue about three times, during the first week of using my Nexus 4 (about half a year ago). I've already had my mind made up to RMA it, but waited for it's shut-off to happen once more to collect some evidence of this problem and... it never happened again. I'm pretty confident that I didn't install anything that might have helped (I only installed BetterBatteryStats to check the instant drain, but really doubt it could change anything, it's just statistics), and I've never factory wiped the phone's data yet.
I've been searching for answers around the internet back in May, but never found anything of value, so my only advice is... wait a little, and if it doesn't get better itself return it to the merchant. My previous HTC phone was restarting almost everyday from the first day I bought it, until a month later I returned it for warranty repairs and after they changed almost all internals of the phone it never crashed again (till today, since I still use it as GPS and media player when running).
Hi
Its the second time this happened.
I went to pick up the phone and he was very warm with the light of hello on. When i turn on the screen had a windows message saying that the phone was hot. someone had something like this or its only mine?
I thing its better return the phone ?
Exchange one
Same here.
the phone is junk!
i have the 950 and its doing the same thing. Its terrible. Hello keeps coming on randomly- event when it just charging and no one is moving infront of it. what crap! in my pocket the phone gets so hot that i can feel it through my clothes. battery drain is ridiclous! anyways it sucks!
am
Got my 950XL unlocked from CPW on evening of Tuesday 8th. Out of the box it was running 10.0.10586.0
I set up the phone including turning on Glance and Hello and left it overnight to fully charge
Took if off charge 6am on Friday. Battery was getting low by the time I got home at 6pm (around 20%)
Tried wireless charging with my Tylt - the Tylt led came on and the battery charging indicator came on on the phone so I thought it was OK but a couple of hours later the charge had only gone up by about 5% and the phone was extremely hot.
Switched to charging with the supplied cable and it charged up ok but stayed quite hot.
On Saturday noticed that the battery went from around 80% to 20% in less than 4 hours and the phone was on standby for most of that time
Tried to turn off Hello to see if that would make a difference but it kept turning itself back on.
Also phone update said that 10.0.10586.29 was available but it wouldn't download.....said it was downloading but stayed at 0%.
So on Saturday evening I did a hard reset and left Glance and Hello off.
Updated to 10586.29 and so far no problems with battery or overheating, on Sunday the battery went from 100% at 7am to around 70% at 9pm, very light use during the day
I
The overheating is primarily caused by an update failing to come down. its also draining the battery. Once the update downloaded and installled, I've had no further heat or battery issues.
To get it to download I disconnected from wifi and rebooted.
Reconnected to wifi and had the unit plugged into the mains.
the update had a failed message on it so hit it to try again.
Took about 30 minutes and everything was done.
I turn off glance and nothing happen. Turn on today, now i will see if happen again. Glance in 30seconds. But i think i will exchange for a new one. I now this is a beta phone but this overheating is bad.
