I just purchased a new NT two days ago. Battery life was fine over its first night. Last night, however, saw some odd usage.
The NT was fully charged and then used to watch 30mins of streaming video. When I was done, I turned the screen off (sleep mode?), left WiFi on, and went to bed. By the time I woke up 8 hours later, the NT was completely dead and refused to turn on without first being charged.
Some background, it's a rooted 1.4.0 running the stock Nook OS with GoLauncherEx as the shell. I've used the SystemUI mod to have the N button act as a Home button and place persistent Back/Menu buttons on the status bar. I've also used the mod that fixes the white text on menus issue.
After I got it turned back on, I noticed that from the moment I unplugged it from the charger, the battery took a steady dive to 0% (the stat chart is basically a 45o angle). It also says the phone was "awake" almost all night despite the screen being off. Nook's official customer support response was to turn WiFi off and be more mindful of my usage, but I really feel that even with WiFi on, it shouldn't die within 8 hours of no use.
So, does anyone have any ideas on what is keeping the device "awake" all the time or have any tricks to conserve battery life? If you need an installed app list, screenshot of the battery stats, or whatever to better diagnose this just let me know. Appreciate your help!
tl;dr: Brand-new, rooted 1.4.0 NT dies after 8 hours of no use. Help?

Hello everyone!
Firstly I am totally happy with my new Galaxy S2. But then happened something strange....
Yesterday evening I plugged in my phone and loaded it fully, I played a few games for about 1 1/2 hours and the battery was fully loaded, then I turned off my phone (and it seems that it made an full shutdown, because it turns the lights off and vibrates when it shutdown successfully).
Today in the morning I wanted to turn on my phone... nothing happened After a few tries to turn it on... I plugged it in... and see there... it loads... from 0%??!
How is this possible if the phone was shutdown all the time?!
I have original rom, nothing modified yet and there are no updates available for my phone.
How is this possible if the phone was shutdown all the time?!
No answer to that if it was a charged and shut off .

What do you mean by that? You were playing for 1½ hours and the battery was fully loaded !, or you kept it charging while playing
Regards.

I kept it charging while I was playing (it already was fully loaded at this moment) and later I turned my phone off with 100% battery. XD
In the morning it was not possible to turn it on, so I plugged it in again and it shows the loading screen with an totally empty battery and an yellow triangle. I really don't understand how this is possible..
Yellow Triangle? You are rooted right? And what other apps were you running when you turned your phone off, SetCPU or something like that?
No, I am not rooted not yet ^^
I think the yellow triangle appear when you plug in your galaxy S II and battery is lower than 5%. (When plugged in turned off)
Is it possible that gaming consumes much more energy even if plugged in? It's the only explanation for me at the moment. But this will also mean that the display of the battery don't update if fully charged and kept plugged in... mhmm.

Sorry I don't know about that. I thought Yellow triangle only appears when you are on an unsecured kernel/non official Samsung kernel, when rooted.
And while you were Gaming with charging, definitely Gaming took more battery out of your phone than the charging was filling in. But still, full drainage of 100% battery overnight is NOT normal, that's all I can say atm.
Regards.
This particular problem just happened to me. The yellow triangle in question (no photo for obvious reasons), is overlayed on top of the charging logo that appears when the phone is completely powered off.
I hoped it was my battery...not the case, like others, I believe the problem to be originating from a loose micro-usb connector. I slightly jiggled the usb side to side (very slightly) and the problem cleared up long enough to boot. It has returned and I am most displeased as I ordered from Expansys Canada and with a device I can't turn on and return to stock I am basically SOL.
Ugh, and I was hyping you guys up so much Samsung!
Your battery overheated and could not charge. When I play games and charge at the same time, the battery gets hot and I get an overheating notice. This is when you get the yellow triangle. It doesn't charge after that and I find that I have to remove the battery to get it to somehow "reset" the internal temperature sensor before it will charge again.
*kick* (since topic title fits my problem..)
So: battery nearly flat after reboot. Happened to me three times now, twice within one 'battery cycle'. First time it happened, the standard digital clock didn't refresh, so I restarted the phone. Before restart, battery was above 30%, after restart it was around 10. Afterwards, the level started climbing back towards 23 (hence, without me charging the device). Used it, so did not verify whether it would actually climb all the way back to its original level of over 30%, but the level seemed accurate because it lasted for many more hours until it reached 15%.
Last night, after a restart, batt dropped from high-20's to 8%. Because of the previous experience, I didn't charge, but let it be during the night. This morning, 8 hours later, batt level was back at 26%.. the battery graph showed a nice upward curve.
Couple of hours later, phone doesn't wake up and has switched off apparently. Startup reveals batt to be below 10% again.
Anyone experienced a similar scenario?
(Vodafone branded non-rooted GSII, PDA:KG2/Phone:KG1/CSC:KE2).
This has happened a couple of times more since then, I guess 6 times in total now. Have made screenshots of the battery level to provide an idea of what's happening, or at least, what it looks like. However, I can't post outside links yet.
Without recharging, battery level manages to climb back almost to initial level.
No-one with similar experiences? I have done no rooting, custom ROM's whatsoever.
(Vodafone branded GSII, PDA:KG2/Phone:KG1/CSC:KE2).
I was web browsing and suddenly the phone rebooted, and the battery charge dropped to the level seen in the screenshot. It's the first time happening. I'm on cm7 latest nightly with cg6.

OK, so here's the deal:
Had my S2 for about a month now, and apart from the battery draining faster then would be nice this phone is an absolute killer cool thing
But now here is the issue:
In the month I had this phone I had 3 occasions of the battery draining to empty while it is ON the original wall-charger. Do describe the most recent case:
Im at work, and I see the battery could use some charging soon. So I plug it in, leave it for a bit with screen turned off. A bit later I pick it up whilst still in charger to do some minour things on it. After a few minutes (phone very hot in mean time, but known issue) it gives me a pop-up that I need to plug in the charger which it is already on. So I check my Juice Plotter and notice that indeed it sees it is on the charger, but the line which shows you the level your battery is charged is coloured red and has been dropping just as fast as before I plugged it in. Near critically empty?
So to check if some app is draining the juice in the background i closes all running services and apps and leave it for a moment. I check: only about 1 percent charge left? O - M - G.
So i did what I did in previous 2 cases: Turn phone off to get it charged to at least about 20% (how nice that someone/something else is forcing me to be unreachable by phone ). When I turn it back on at that point, I check juiceplotter first... No real changes or battery charging for first maybe 5 minutes (it just stays at a flatline level) and then finally it starts charging again slowly but steadily.
What's the deal here?
Since 1st time this happened i started keeping my home screen as clean as possible and such to be as energy-efficient as possible. Barely use screen-brightness (by the way the auto-brightness sucks). On 1st page of homescreen I have the Juice plotter widget showing me battery depletion / battery charge time levels. Funny that in the explained problem cases you can actually see the time till charged getting longer and longer by the minute :S
last night i had my tbolt charging. the phone was off while charging, and it was left plugged in for a few hours beyond the led changing over to green.
after i unplugged the phone and went to turn it on, well... it wouldn't turn on. i did feel the initial vibrate i always get right before the htc screen comes on, however, the screen never came on. i ended up having to pop the battery out and then after putting it back in the phone booted normally.
however, now it seems as though my battery is draining way faster than it has been. i've had the phone a few weeks and the battery has been properly conditioned. after taking it off the charger at approx 2:00am this morning, a mere 10 hours later (whilst completely in standby for the entire time) it's already down to 83%.
what gives? could this just be an accuracy issue with the reported levels? i've read about fully charging and booting in to recovery to reset battery stats. or is it a far worse issue and something has happened to my phone that's damaged the battery in some way?
btw, i'm rooted and running das bamf remix 1.7 with imoseyon's leankernel (running in normal mode with swap enabled).
just a quick update:
after some moderate use (texting, web browsing, downloaded a few market apps) the battery continues to drop much faster than it ever did before. i'm using wifi at the moment.
Have you cleared battery stats lately?

no, but i'm going to do just that tomorrow after work when i have a chance to fully charge the phone.
one other thing i just realized that may be contributing to the problem though... my g/f was playing around with my phone and she signed into latitude. doh!
hi guys , i got some problem with the information displayed for my razr maxx. the thing is the battery usage curve won't change for the first 10% of power drain, and the awake bar and screen on bar are full. but when the battery drops to 80% and below, the curve starts to count from the 80% position, what is going on? how can i fix it ?
here is the screenshot
How many times have you already charged that battery from 0% to 100% and drained it back again to 0%?
Seems like a simple calibration issue that should have no effect in real world battery performance.
Had that too. If you want to know more about this, look up "batterystats.bin".
So, if you haven't done what I said in the first line, do it and report back.
i have tried delete the .bin file bwfore, nothing changed. i think i will try to charge it from 0to 100again see if there will be any change. btw will the battery calibration apps solve this?

Read that. You don't have to do anything, just let your razr get some charge cycles and the readouts will be right. Remember: There is no need to tinker with this, as this has no effect except for cosmetic terms.
thanks for the information. one more thing, the battery indicator always shows that the screen on and awake time are the same, even after i turn off the screen and play music for an hour. is this normal? or the system keeps recognizing the status of the screen as on? how should i deal with this?
I would just wait a few days (read: charge cycles) and look again. Indeed strange, but if your battery doesn't get drained this also seems just to be another cosmetic issue.
actually it seems it has been more energy draining than before. it wouldn't drop 1% when i turned on flight mode at night and checked it in the morning. but now even i turn on flight mode it drops about 5% next morning.

Don't count on the battery percentage today. Look again tomorrow/after some charge cycles.
The battery readouts need to be calibrated to display the correct battery level.
I had the same "issues" (in fact, those don't seem to be real issues) and they went away. I assume your razr will behave the same as mine
Is the phone still new? I know mine was a little wonky until the charging and the meter apparently calibrated themselves to Maxx's battery Ever since, it's been very accurate.
yes it is still new. i got it about half a month ago. just got it charged to 100% from 0%. gonna see what will happen。
Hi guys,
I just got this phone but it's having a weird problem. The battery % seems to drop off in big jumps instead of gradually.
For instance, I also have an Xperia Play, if I run the LED as a flashlight, I can see over a few minutes the battery % goes down gradually.
This new phone, Samsung Galaxy Q, if I run the flashlight, nothing changes in a few minutes. But if I check back after locking the phone a few minutes later, it shows a battery drain.
Another example, before I went to bed, I had it charged to 100%. When I woke up 7 hours later, I checked and it was still at 100%. I checked after I got dressed a few minutes later, and it just dropped to 90%. During my trip to work about half way while playing music, half way to work, it was down to about 86%, kept checking, and no changes. When I got to work at my desk, the battery hit 77%.
My battery graph when I goto battery use is basically this, straight line....DROP, straight line...DROP, etc.
Has ANYONE ever had this problem?
I have seen this happening when the battery gets older.. is this a new device with a new battery?? If it is a new device, your battery might be damaged. you should better get it replaced.
