Hello,
I have this problem for a while, where my battery percentage suddenly drops to 0% causing my phone to shut down. When I boot it up again it says 1%, or shuts down right before my login screen appears. After booting it a few times it will say the *real* percentage again, which is usually around 40%. I could also skip the multiple reboots by plugging the charger in before booting causing it to also display the original percentage.
I have tried recalibrating the battery a few times (by using an app that removes a file that stores the battery percentages), but unfortunately that did not help. I've included a picture of my battery statistics which show how my battery percentage changes.
Thanks for reading .
It means you have dead battery for, good luck ?

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.
Hello, I have a very annoying issue.
For some reason, my battery indicator doesn't refresh and get stuck a the percentage the battery is at when booting. For example : if the real percentage of the battery is 71%, when booting, it will show 71%, forever. Even if I use wifi for hour or more !
If I power off my phone, take the battery off, press the ON button for a while, then put the battery back and start it again, the battery show a lower percentage (the real one). But then stay forever at this new value.
What is wrong ? I tried wiping everything, flashed 3 different roms, tried with 3 different batteries with no success...
Help ?

Some more information would be useful, like:
Which bootloader you are. Old or New?
Which Rom's you used?
BTW, which Kernel and it's version?
hi
The battery lasts a few hours?
So I've never had a problem with my battery at all. I easily got 6h of screen on time and everything was great.
Recently my Nook started to randomly shut off at around 20-30 %. It "popped" and it was off. Didn't reboot either. Like the battery was dead.
I would have to charge it again to be able to power it on.
Also the stats seemed to be off. The lockscreen sometimes told me it's fully charged and whenever I unplugged my Nook it wasn't fully charged. The battery LED also sometimes flashes green/red during charging.
I only get around 2-3 h of SOT at the moment.
I tried reflashing a couple of times (with full wipes) but the problem occured again.
So my question is: Are my battery stats messed up? Does it just stop charging at a certain point because it thinks it's fully charged but it isn't in reality?
Any ideas (on how to fix this)?

It's almost sure that you battery is degrading very fast. But its my advice to re-calibrate your battery. Set your screen brightness to max setting and leave it on until it shuts down. Now don't power it on. Leave it charging for around 2 and half hour.
Now install geekbench benchmark app and test your battery.
If you heard a pop noise, the battery probably delaminated/micro-exploded. (Li-Ion's tend to swell and fail from the heat of (over)charging.)
There's a company, newpower99.com, who has a YouTube video on replacing the battery in the HD+. The battery sold for $25 US last year, but now that our batteries are beginning to degrade, they're out of stock.
I found another site selling replacement batteries for $80. (portatronics.com)
I've noticed that my screen-on time has dropped from 6 hous to 5.5. Maybe the Nokia N1 will be available and rooted by the time I hit 3 hours.

I'm having the same issues, and reading this reminded me of trying BatteryCalibration to reset the battery since my nook HD+ stock OS is rooted.
I had this problem several times before I installed CM. Usually, it happened when there was an update available, and when the Nook started to update, it factory reset itself.

Hi.
I have some trouble with my battery. Few times my battery has been completly discharged. A few second before turn off my screen backlight began to blink like the battery voltage was too low. I observed what happening then with voltage, it was under 3000mv and it's obvious, voltage was to low to backlight screen properly. Some times from 25% my phone is able to trun off himself after 30 sec after I trun on backlight.
I observed unusual thing. My battery status in percents are not real (real is lower). If I turn off phone, remove battery for few seconds and i turn on phone some times I have 15% less than before turn off.
I suppose the battery percent status is counting from voltage. So my conclusion is the battery stats are not up to date.
I tried wipe battery stats (I known it's not hiving any effect, but I did have better idea). I also tried battery calibration.
Do anyone have any idea why battery voltage are not up to date and how fix it?
Edit:
It's happening on CM11, CM12 and Stock.
