Hi there.
I am posting this because I have absolutely no idea what happened to my phone last night.
I watched a couple of YouTube videos before going to sleep. I restarted my phone before I plugged it in - no particular reason, kinda happened by accident. I plugged it in after the phone booted up tho.
For some reason the CPU was working hard all night. It looks like the phone stopped charging once it reached 45 degrees Celsius (or is that a coincidence?). At some point it started charging again, and stopped at around 86%. Why? I am so confused. I really hope a night of battery temperatures between 40 and 50(!) degrees didn't kill my battery life in general now.
I just want to understand what happened lol. Btw couldn't find a process/app that had any significant Stay Awake time! (maybe it reset?)
Cheers
PS I'm on 930W8, PG1, no root or nothing like that, stock rom
Edit: it is also weird that the graphs show WiFi to be active all night. I have it set so that the phone sleeps WiFi when not in use, to save battery in standby. Well I guess it was not in standby lol

I will tell ya, I have been extremely disappointed by my new MT4G's battery since I got it just before Christmas.
If I unplug at 7am to work (I work at home) I can bring it in, not use it all morning, and by 2 pm I was looking at 70% battery with almost zero use? If I used the phone at all, I'd be looking at charging it by 3 pm.
Needless to say, if I went to sleep, I HAD to have the thing plugged in to charge as it was draining very fast while doing nothing.
Never really could figure out why, but yesterday mid day I installed Cyanogenmod 7 on a full charge and it's 7:53 am today (I didn't plug my phone in to charge last night) and I'm still at 50%.
No juice defender, nothing, didn't plug it in (I forgot, and when that usually happens my alarm doesn't go off because it's dead).
If you're having massive battery issues.......try CM7...I had tried everything on glacier roms to get better life. My phone would randomly wake up...now it doesn't.
Anyone have a similar experience moving to CM Roms?
That sounds like it might be worth checking out, but I will wait until the official cm7 release is out.
I am using setcpu to underclock my phone while the display is off. I unplug at around 8 AM, and I can get to 1 or 2 pm with 98-99% of my battery remaining with no use. I went to sleep last night around 12 with 29% left, and I woke up at around 9 with about 27% left. I should also add that I spent a pretty solid amount of time yesterday browsing the internet and playing angry birds, so I was pretty pumped to have that kind of battery left at the end of the day.

what's weird is I could play a game a lot, or do something considered heavy use and I really wouldn't get a ton of battery drain. It would drain a lot when I seemingly wouldn't do anything.
I too have setCPU profiles, and had to use JuiceDefender to even make it to the evening with light use.
I've had 4 different Android phones now, this was the only one that acted like this (all were battery hogs, but nothing on this level...Droid, N1, Vibrant, MT4G)
as far as waiting on CM7.....I didn't see any reason to wait. Everything seems to work very great with the newest builds and I don't really have many/any issues.
Was worth the switch for me to fix the battery issues with the stock I was having.
I STILL think it had to be a wake issue...ie, the phone waking a bunch during the night and turning the screen on/processes on. I haven't noticed CM7 randomly wake my phone once since I changed.
of course, it could be something kernel related too
I have been having problems with my battery life pretty much since I have had this phone. I downloaded spare parts app to give me some insight because I have also noticed several times phone seems warm even when screen has been off for some time.
As of right now today, to give an example, my phone has been unplugged for the last 10hours and I only have 44% battery left. Says display is responsible for 71% of battery use yet screen has only been on for 44min of that time (and I have the brightness turned all the way down). According to spare parts "other usage" my "running" time is cause for 35% of batter use at over 3hours.
With these things in consideration I feel that there is something that is stopping the phone from properly sleeping due to the phone being warm at times display has been off for a while and the contrast between screen on and running time. Partial wake usage doesn't show much running under it as most listed items have only a sliver of a bar showing.
Can someone please lend me some guidance on how to further troubleshoot this problem?
i mean that type of battery consumption doesnt seem irregular to me...im at close to 10 hours for the day and have 59% left.
Are you in a shaky signal area? Thats one reason my phone gets warm. especially if its a fringe area where it cant decide between a 3G signal or 4G signal.
In spare parts there is a option for partial wake lock. If something is stuck at 100%, then you know you yuo have a rogue app thats causing your phone not to sleep
But can you confirm it being normal to see 34% time running under other usage settings for spare parts? Partial wake usage as said doesn't show much keeping a wake lock going.
As for signal, not too sure, very rarely if ever see a 3g change over. Is usually at 4g and occassionally hitting edge.
WOW, you get that good of battery out of yours? that seems epic haha, i get 3-4 hours tops.. i mean i abuse it, but still..
I charge mine at night. Ran it from 7am to 12am and it was at 34%.
Yeah see...7am to 12am and 34% remaining? No way I get that.
If it werent for the results I'm posting regarding "running" percentage from spare parts other usage and the screen on time I would just accept it as a phone deemed to have bad battery life, but it seems to me like something is going on and I guess I'm looking for someone to confirm or dismiss my suspicions.
Maybe I'm also a little spoiled coming off my G2 that was rooted running CM Rom and CPU ramping/cut down which in combination gave me, under the same amount of use, a situation where I was getting home at night and still having 40-50% battery left in comparison to the 15% I commonly see now.

once some custom kernels come out that let you uv/uc/oc then i would say you can expect the same type of results..i just went on a trip with a friend who has a g2 and he was constantly crying about his battery dying, (stock), where as I only had to charge mine on average 1.5 times a day with moderate to heavy usage. I find this battery phenomenal compared to all the other android devices ive owned and tested
damn!
i charge mine every other day.. hehehe i dont abuse it or anything though.. just regular internet every few minutes or so.. i have the BETA juicedefender installed guess that helps a lot. data is off when the screen is off, set it to agressive..
here is the app hope it helps...
I noticed the same problem,i brought this phone on saturday and was very impressed with the battery until yesterday night I noticed the same thing, my phone was at 50% and I had it sleeping then I get the battery low notification 10 minutes later and the back of the phone was real hot. This can't be normal cuz I have the same apps installed from 2 days ago and I was using the phone heavily even using mobile ap and still didn't have this problem, if you guys find a solution please share it with me.
hi all...
soo after my comments over a week ago on the aokp website for this build, i decided afterall to take the plunge and update. i was on b26, so subsequently had to flash b27 and then this. everything has gone absolutely swimmingly with no issues at all so far....
HOWEVER>>>>>
I am faced with a very puzzling quirk. its by nooooo means a problem at all, infact it quite the opposite!!! let me explain.
i've started charging my phone in the evening these days for some stupid reason and then, when charged taking it off and going to bed. After getting this milestone on, my battery has been killed over night, draining to around 15%. Normally, it would drain to around 70% and be flat by the end of the day ready for charging again.
This continued for a few days when i decided to root out the cause of the massive overnite idle drain. I installed a fantastic free app called Badass Battery Monitor (which i highly recommend btw!), and over a period of a couple of days the offending app was weeded out. It was Nova Launcher. This had never happened to me before and couldn't understand it. So, as part of my diagnostics, I decided to confirm the findings by removing it and just using stock.
Over a couple of days monitoring, with exactly the same charging method, my battery levels returned to normal drainage with around 75% battery left by the morning. Fantastic. I had found the problem fixed it and got back to normal. Soooo where is the quirk i here you say!!!? lol Well......
On average, from everything i've read in forums, battery drain overnight while phone in standby is around 20/30%, so mine WAS right up there with the majority of you.
Last night, i decided to charge to full and then wipe battery stats. Which i did. Now, bare in mind here that I ONLY have the standard battery that is supplied with the Galaxy Nexus. I got up this morning, and to my utter amazement, my battery had only drained 2%
Now been incredibly realisting here based on average overnight drains, i was 100% sure that this was deffo an error. I have done everything from restarting the phone, taking the battery out, but still the level in my battery was saying the same.
As I sit here writing this, I have been streaming a radio station via wifi on the phone for the last 2 hrs, and atm my battery is telling me that it is STILL 85% full.
I am DEFFO not complaining, but i'm sure now, you can see why the hell i am so puzzled! HOW THE HELL IS THIS HAPPENING, because i can genuinely find no explanation at all for it
as a follow up, it is now more or less 5 hrs since my orginal post, and my battery is reporting that it is 75% full
Jeesh, 20 to 30 idle drain overnight? My phone drains about 3 to 5 overnight which is typically 8 hours of sleep.

Interesting quirk. Are you a heavy or a light user? It'd be nice to see how it drains after a full drain and recharge.

well, to see if what was been reported was correct, i've been an absolute heavy user today. i have wifi on, ive streamed radio via internet for around 3 hrs, ive been playing all sorts of games and watched a few youtube vids. and my battery is atm reporting 74% life left
so here i am, STILL very very puzzled..
my battery life is just going and going with no signs of running flat... have a look at these screenshots and give me an explanation as to why i suddenly have a super battery!
MAYBE you really have a super battery or your mobile is glitched and shows the battery like that due to laG?
I'm on miui and I lose 0% overnight. It just depends on the ROM, but 20-30% is ridiculous!

Your states do not seem super impressive. On most phones the screen is the biggest drain. You show 49% battery with a screen on of only 1 hour. After 33 hours you've only used your phone for 1 hour screen on. Thats VERY little.
I usually get 2.5-3 hours of screen on time for my galaxy nexus.

Thanks for the app recommendation! Been looking for something like it all day.
This will depend on ROM/Radio/Kernel user installed programs/sync etc but 2-6% is normal drain over night anyone with 20% needs to seriously look @ battery stats and work out what's causing wake locks.
Also not forgetting most phones need to bed in after a flash which can take 2-3 days before we see real battery info.
Hello,
I bought this phone a month ago. At first the battery lasted quite well, I got around 5 hours of screen time with battery life to spare. Unfortunately, about 2 weeks ago I accidentally left the phone under my pillow and fell asleep on it- causing it to overheat a tad bit (I woke up 3 hours later and it was very warm to the touch and had turned off). After charging it up, I continued to use it normally but noticed that the battery would drain a little bit quicker than normal. Before I could easily go around 10 hours with heavy use and have 40% battery left, now after 10 hours it's left with about 15-20%. I am a heavy user but I haven't properly checked how much screen time I'm getting now, however I'll update that later.
As for the main problem- last night I charged my phone before sleeping (100%) and when I woke up in the morning it was turned off. I turned it on only to see that my battery had drained to 0% while on standby all night- whereas overnight I usually only lose around 2-3% battery.
After charging my phone up for 15 minutes- the battery level again returned to 100%. I only charge my phone through my laptop via USB. What happened here? Is my battery deteriorating? Should I get the phone replaced? I would appreciate any input on the matter. Thanks.
Also I've attached the screenshots showing how my battery died and how it was quickly restored. Can someone explain this occurrence?

Your sudden battery drop has nothing to do with what happened before.
Several people already mentioned this sudden battery drop as you can read in this thread, http://forum.xda-developers.com/showthread.php?t=2545553 and http://forum.xda-developers.com/showthread.php?t=2678909
No reason to return your device, its a know issue.
Drain your battery completly then charge your phone to 100%, turn the phone one and leave it to charge a hour more. Essentialy you have to recalibrate your battery.
So a brief update regarding SOT.
I left home with 90% charge this morning. Used the phone for 8 hours and it went down to 20% - granted, with heavy use.
Got 4.5 hours of SOT. Is this about average? imo I feel like this falls a bit below average. Ill check other threads as well and compare, but as far as I know, I feel like I should be getting a *little* more juice out of my phone. Data connection was on throughout, and some games were played and pictures taken.
Anyone else feel like they're getting sub-par use out of their battery?
*screenshots provided.
- checked the other threads, looks like ~5 hrs SOT is the most this phone puts out?
Same here.
Are there any news from Motorola?

I bought my phone new when the Galaxy S6 first came out and have not rooted it.
For while now my battery life has been bad but consistent, or I would say acceptable given what is running in the background. With normal usage, including connecting to a bluetooth watch, LTE, and location services on, my phone battery would drop from around 100% starting at 7am to around 70% by noon. On weekends when I'm just at home and have it on Wifi instead and no bluetooth, it takes until around 6pm to drain to 70%. These numbers have been consistent, give or take 5% for over a year.
The problem started recently when I received an OS update. I can't remember if I was already on Android 7.0 before this update and it was just a minor update for something else, or if this updated me to 7.0 from 6.x
The first week after the update the battery was great. With no change in the way I use my phone I was able to go the entire day without recharging. By noon I was still at 85-90% and by around 7pm it showed 60-70%. So I was able to go the entire day without recharging for almost 2 weeks after the update.
The problem started 3 days ago when suddenly the battery is draining like crazy, and it seems like there's something weird with the battery indicator and the way it's charging. Again, nothing has changed in the way I use my phone.
Now, when I use it, the battery will go down by 1% every minute. And even when I don't use it, it will be down to 70% by 8am and 20% by noon. The stranger thing is when I try to charge it.
Before, with normal use, it will take around 1 hour to charge my every night. Also, the indicator showing how much time is remaining is pretty accurate as well. Now, when I charge it, it seems to take a lot longer. The time indicator will sometimes fluctuate. It may show a realistic time like 45mins remaining, then change to 10mins, then back to 45mins. Also, the times seem to be incorrect. For example, before if I'm at 85% it might take another 15-20mins to reach 100%. Now, it will be at 85%, say it will take 40mins, but after 40mins it's still only showing 90%.
I tried restarting my phone normally, and resetting it by pressing the the vol down and power buttons. I also tried other power saving methods like forcing apps to sleep when I'm not using them. But for some reason, the battery is still draining like crazy.
At this point, given what is going on when I charge the battery, I'm wondering if the real problem is the OS update screwed up the way the phone is reading the battery's power and not that the battery is actually being drained. Maybe the battery in fact is still at 70% by noon even though it says 20%.
Sorry for the long post, I just wanted to be as detailed as possible given that this seems to be different from some of the other battery related problems I've read about on the forums.
Any help or insight will be appreciated.
replace the internal battery
