Anyone else experience this? I was next to my gf and seen her tablet start flickering and she handed it to me and it was at 5% and it shutdown and wouldn't power back up until I plugged it in. Is this normal?
Battery stats are never always 100 percent accurate.. rule of thumb do not deplete the battery completely. Once below 10% it's time to recharge.
Yep, same for me. I try to keep it between 25-85% allt the time. Been doing it for about three months and now it barely flickers at all.

I'm worrying about my battery. The main thing is, it drains really fast. In flight mode and nothing else on it drains like 2% each hour. So overnight, most of the time it drains like 16%. Today i started with 100% in the morning. Used GPS for 1 hour, made a phonecall for 20mins in total time. My battery indicator said there was 30% left :/ I know this thing eats batteries, but this is insane. Because i noticed an incorrect display of the battery the last few days i gave it a soft reset. After the reset i saw the battery had only 4% left, not even 30%, but 4! :|
Many times when the phone is saying i have 'insert number' percentage of battery left it's incorrect. Because when i give it a soft reset, it changes the number. Sometimes i get more percentage back, and sometimes it drops.
One hour ago i plugged it on the charger, checked 45min ago, and it was still on 31% battery :| Then, like 10min later i suddenly saw a green light from my phone and it was full.
I've never had a device with a broken battery and i don't know the symptoms, but is this normal or is it likely that my battery is dying?
A little kick!
I let my phone run down to 16% and I was planning to let it go to 10% before plugging it in to charge.
At 16% I was on wifi and browsing websites when it just turned the screen off, made a warning sound and flashed the red battery light. After about 3 sec it started vibrating non stop which made me think of the 'discharge' feature on some phones, (which quickly uses/discharges the battery..), I didn't want it to go to 0% so I pressed (tapped not held) the power button which seemed to turn it off. I turned it back on, plugged in, and it booted up showing 0% batt.
My question is, has anyone come across this before? Should the batt % be this incorrect? and why did it vibrate..
My phone has been frequently below 15% without problems (yes, it's not very good for the battery, I know). It should vibrate once when it hits 15% and display the charge message, but that's it.
Happened once though that my battery discharged from 50% to 0 in literally 1 second, don't know what happened then, but it hasn't happened again.
Sounds like either your battery shorted or the calibration on battery % was way off on your phone. Try charging it to full and see what happens the next time you reach 16%, it might've fixed itself.
The other day my Nexus turned off at 11% :/
wipe battery stats after a full charge.. guess that will solve the problem
this isnt just a froyo issue, i am still on 2.1 and my battery dies at 8% EVERY time. it turns off, and when i turn it back on, it shows 0% but it died at 8%. its been this way the entire time i've owned the nexus. i'm not rooted so i never wiped the battery log files yet....but i will soon enough.
Ya my phone dies at 20% everytime. I just ordered a new one though

do that.
On 2.1 my N1, first my N1 had its multitouch laggy starting at 15%, then after some day of uses it shuts down at 1%.
Your battery just need to be calibrate.
I'm trying to nail down if this is normal behavior or not my phone always shutdowns itself when the battery level goes below 7%, no matter what.
then I turn it on it boots and shows 0% of battery left then it shutdown again, next time I try it's totally dead.
Tried with a battery calibration improved the overall battery life but that mark is still there.
Is that normal? I mean when I used to have a G1 it lasted until 1% or so.. 7% can be very well an extra hour of usage that I'm loosing.

I've noticed the same thing. It'll be interesting to see if anyone has a solution.
7% of battery life is just a number. It could very well be inaccurate, and simply reporting 7% when you actually have 0%. When you reboot and it shows 0% just backs this idea up. You are not "losing" an hour of battery life, you simply never had it.
To check this, use spare parts to look at the voltage of your battery when it approaches 7%.
Also, this belongs in the QA section.
I'll give it a try, interesting is the fact that both Cyanogen RC3 and Battery Monitor are reporting the same thing.
Will keep an eye on the voltage, what should it say ? something near 0?
seriously?
AFAIK li-on battery never be below 5% or 7% why?
because if you get below of this the battery will be dead and will not work anymore. so thats normal.

I've also read its normal but if its normal why isn't it calibrated to show 0% when its actually at 7%? My phone goes off at ~10%
btw there are so many battery threads lately.. http://forum.xda-developers.com/showthread.php?t=702167
Yeh, mine also goes off at around 10%.
it seems normal then , time to get myself a spare battery ... travel can be painful if no power outlet / usb port is near me
Yes its kinda normal. My phone has always shut down at 8% from day 1. I think its because of what we're talking about in the battery cal thread personally.
After charging my battery fully to 100%, I unplug it from the charger and without even turning the screen on, the battery drains to 92% within one hour. I check the battery stats and there are maybe only a couple wakes during this time.
Sometimes, the battery shows a certain percentage longer than others. Example, my phone will be on 65% longer than it would be on 60%.
Battery still gives me a solid 2 days usage with about 3+ hours screen on time. The service menu also says that the battery is good.
Is there a way to get the battery reading to show more accurately?
Thanks,
Hope I could Help You
For your battery problem, I guess you could try calibrating it. And also try to install "Greenify" along with "Clean Master or 360 Security" and try to close all running apps before turning off the screen. I also turn on Stamina Mode when the battery is at 100%, in an attempt to further save battery life. And the result has been kinda meh, but well, battery drains about 1% per hour. It lasts about a day and half with light usage. In my case, light usage being, browsing, youtube videos for about 2 hours, listening to music, social networking and taking some pictures

Hey,
im using greenify (my phone is rooted). Battery is quite good for me though. I get about 3 days with light usage. I start charging my phone again when the battery gets to anywhere between 10-20%.
I read that maybe its better not to let it get so low?
I have no wake locks either.
Umm.. IMO, 10-20% is okay. I usually charge the phone when the battery gets around 5%. I read somewhere that charging battery too early can affect the battery's overall standby time (reducing it). It's better not to let the battery reach 0% though.
I had that happen with my Samsung Galaxy Note 2 earlier. I once let the battery dip all the way to 0% many times. After a few charge cycles, I found out that the battery was dead and wouldn't charge at all so I ended up buying a new battery :-/
Umm.. Coming back to our Z1's, could you try putting the phone in stamina mode everytime the phone is kept on standby mode? This boosted my battery life a lot I even put my phone on stamina mode throughout the whole night yesterday to test the battery life again, and when I switched on in the morning, I saw that the battery had dipped by just 2% (standby time of 7 hours). I'm really confused how your battery drops so fast, 100% to 92%.
Could you try calibrating the battery and then putting it in Stamina Mode while on Stanby and tell me the results? I hope I could help :fingers-crossed:

Yeah i could try to calibrate it. Im a little confused on what you do to calibrate the battery (ive read way to many opinions on this). Can you please tell me the steps.

When my battery is getting low, I've started to notice recently that it never falls below 4%. Instead of counting down to 1% and shutting off, it just shoots down to 0% and immediately starts the "Power Off" screen. Is this normal? Anyone else's Nexus 6 do this?
I've seen the post about the Nexus 6 that would shut off at 73% consistently and I guess this could be related to a bad battery or calibration, but I was just curious.

I've only ran it down that far once and yes, it shut down at 3%
@j.bruha I assume you know this, but just in case - Li-Po batteries don't really do well with extremely low charge levels. Try to avoid depleting the battery charge level to anywhere close to 0. Most folks recommend keeping the battery level at 30% or higher for longer overall battery life (not the time that your battery lasts from charge to charge, but the number of months/years before you will need to replace the battery itself)
Mine goes all the way down to 1 % and shuts down. I can still use phone when it shows me 2% left. Never seen it shut down at 4%. Discharge battery and fully charge it, Sometimes it does help. good luck.

I think there's a lot of over thought about caring for batteries. I think the best advice is to charge it as it needs charging.
Li-Po batteries don't do well at extremely low charge levels. That's an understatement. They become physically volatile and very actually dangerous to use. This is why when you deplete your battery from 100% to 0%, you're actually discharging from 100% to something like 20%. The battery chip does not let the battery deplete fully and is calibrated to report that 20% as 0%. There really shouldn't be any harm letting the phone shut down at "0" because it isn't 0.
My phone shuts down at ~1% sometimes 2%. It has shut down at 3 once but it depends. I usually don't run my phone down that low, but if I do I expect it to turn off at some point. I would see if you can have it repeat the behavior so you know whether or not its a bug.
