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.
Hey guys I just picked up the Thrill the other day, and like others I've realized the battery life is horrible on this phone not to mention when I reboot the phone would take a 10-15% out of the battery. Coming from an Atrix I decided to try the battery fix for the Atrix since it worked for me in the past, well after following all the steps in the guide it seems my phone reports the battery more accurate and battery life is better but your mileage will vary. Reboot doesn't take 10-15% out of the batter percentage either so here is the guide and link to the original thread, all credits go to xploited.
PS.. I followed all the steps except for flashing the jug6ernaut's CWM battery fix since it is for gingerbread roms
Link:http://forum.xda-developers.com/showthread.php?t=1198333
Guide:
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )

Not a bad process. I did something similar. Main part is Watchdog and finding out what's draining your battery. On my phone the infringing process is "Suspend". Now, if there were an app that was keeping my phone from suspending and running up the process it would be an easy fix but unfortunately the process with the highest "partial wake" battling my "Suspend" is the "dialer" so unfortunate I'm just gonna have to wait for GB since I have no interest in Rooting or installing roms at this point.
I'll give this a go. Thank you

It did that for an hour then FINALLY reached 0% haha
Maybe a week ago my nexus start to shut down when battery reach 20%. I charged it and every time when my battery reach 20%, says that battery is empty and shut down...
I try to re-install my ROM - same, then i try with another - same, then try again with another - same!
Also i reset my battery stats from clockworkmod at fully charged battery, but guess what... same!
Also i noticed that when charging and it`s on 80-82% lock screen says that the phone is charged.
Next i reset again my battery stats, phone dies on 20% and i drain it leaving the phone in recovery mod. Then charge it. And when my phone reach this time 18% - shut down.
Help please, how to fix this strange bug or i don`t know what is it...
Battery monitor says that my battery age is 94% => Battery seems to be okay, but...who knows.
Even mine shuts down when its at 10 percent. You can try using Battery Dr Saver to calibrate your battery. I've used it and the results are near accurate. The battery percent goes down till 2 percent before it turns off. So you can try that.

How to calibrate using this program, need i clear battery stats from clockwork?!
Click!
Okay i calibrated my battery and on first discharging my phone died on 0% but after charging, with every next discharge my phone dies on 20% ...
Again when charging rate reach 81% system tells me battery is charged. When die on 20% i boot in recovery and phone work for about a 30 min before dies shut down...
Again some ideas or help?
This is important:
St4hli said:
4.) Make the calibration permanent (thx to user "theGanymedes"):
Since the battery age value is somehow rewritten to 94% when you charge your phone whilst turned off, I recommend editing the full40 value accordingly. In order to do that, first start and successfully complete a learning cycle; and then reboot (or power on/off). After this, you shall see the age value of your battery (say XX%).
Now, you should calculate "real" mAh value using this:
Code:
REAL Capacity = "Real" Full40 Value (1452 in Stock etc.) x Age Percentage (0.XX)
Now, we must recalculate the "fake" Full40 value and write it to EEPROM, so that our battery will be always calibrated (even charged off):
Code:
"Fake" Full40 = Real Capacity / 0.94
First, we're setting the age back to 94% - it's because the phone does this when charged off anyway. Then write this new “fake” value to Full40 assignment area in the Learn Prep app in the application, press Save and you're done.. Congrulatulations, you just calibrated your battery, even when it's charged off. NOTE: Since some internal calculations also use Full40 value, I recommend you to write rounded to next value, rather than truncated.
5.) Didn’t work?:
Phone dies to early?:
That might be because some kernels do use a different power supply drivers, and these drivers don't update values so often as chip does. Try writing manually the value of "04" to register 0x10 when your battery reaches to 10% or so.
Learn Failure:
If your new age shows 94% upon rebooting, then learn mode failed and you need to do it again, paying close attention as charging nears 80% and above. This is where learn mode can be lost by rogue apps, auto-updates, calls, etc pulling the current down below the minimum prematurely.

Okay, will check it and i have another question: I use my phone for development and i connect it random to USB Debug (charging). Is this a problem, after learning complete off course? Will this affect on my battery stats and so?
And thanks for quick responses!
In my case, it doesn't affect it and shuts down at 0-1%. I calibrated some months ago and use both USB-charging and AC-charging.
Hello!
Been using my i9000 for about 2 years and 3 days ago i came around a problem that I can't solve. Let me try to explain as good as my english skills will let me.
I`m charging the battery to 100%. I`m unplugging then plugging back my charger a few times to make sure it's charged 100%. Then I`m using my phone as usual for about 2-3 hours (less if I`m playing a movie or listen to music) and my phone automatically shuts off. When I turn it back on, it shows 1-2% battery.
Now, if I let it idle, it will slowly "charge" back up (without the charger plugged). It wont show the charging icon over battery, but it's level will rise to about 60-70%.
If, after I turn it back on I use it intensively, it will shut down in 1-2 minutes. I tried to charge it to full and then enter that root menu (volume up+menu key+power key) to delete the battery stats, but still can't solve the problem.
I can't believe my battery is dieing or having a hardware problem because it started acting like this out of the blue, so I think there's a software problem somewhere (maybe corrupted battery info stats or something). My bet is on the fact that the phone doesn't know the empty and full limits of the battery.
My phone is rooted and using android 2.3.6. Any advice would be highly appreciated, thanks!

Did you get to have yours fixed??
I had the same problem with my I9000, in the same period.. what are the odds?
I replaced the battery, and the battery level weirdness went away, but I'm still having problems charging it. Actually, the battery won't charge in the phone, tried several charges, with different amps. I have an external charger, which will take the battery at 100%, and it will last a few hours in the phone.
I also have another problem: if I have the phone on, with the charger connected, and shut it down, I can only get it back on if I disconnect the charger. I also don't get the battery indicator when the phone is off.
I was using CM10, but then I reverted to stock 2.3.6, tried a few kernels, modems, etc, but none solve my problems.
hi guys
quite basic problem u got there
if ur on 2.3.6, then its natural problem.its not like changing kernel can solved it as it is safety measure for battery in stock ROM.
to answer ur question;
when charging at deepsleep mode nothing will change=
as cpu at min stated,even wifi will be knocked off n sometimes network signal also.
battery suddenly goes up when rebooting or awake from deepsleep=
its ur battery stat+safety measure for battery (hav u heard BLX (Battery Life Xtender) in any cm10 features?) to maintain fone power state.
battery will never goes 100% n u need to plug n unplug again for it to full=
still count as BLX (above) as in this features battery will goes 90% - 95% as its max to make sure battery lasting longer (if not,why do u think u can still use ur battery in full state after 3 years (1000+ cycles) n it still not bubling like old nokia fone?)
fone will not awake when charging (if enter sleep mode) =
check ur kernel n make sure min cpu change to ~200mhz as its min n dont lock ur cpu to its min.if in stock, something wrong with ur home or power (da one trigger awake) button.
da conclusion is, sometimes (3 month calculated) reset ur battery stat (if ur on GB) with app (too many app on Gstore) but needed root n follow strictly step. DO NOT OVERCHARGE (charging n leaving ur fone till morning to discharge) n be thankful this features intact in updated GB so u can use ur battery much longer than nokia fone.
but u can change it by upgrading to cm9 to disable it. charge it with 'stay awake' enable on dev option n u ll get full 100% usage of ur battery
thats all for my morning essay
n thank you for reading (if u try to read)
Regards

Actually we have a thread with battery problem.
1 Turn off your phone.
2 Charging phone without turning on to full and switch on then continue charging to 100%
3 When getting 100% signal, unplug quickly.
4 Pull off the battery and put it anywhere.
5 Press power buton copule time
6 Wait for 20 min
7 Meanwhile, take this opportunity to dust off the internal compartment.
8 Put back the battery on the right side.
9 Turn on the phone.
10 Pray the Battery god
11 ... and voilà !
My phone got weird battery problem
My phone is 2 yr old & battery replaced last yr
S Off using custom rom insertcoin senseven artmod
I think physically battery is ok
Problem is phone shows battery discharging very quickly
after that what I do
reset battery stats by power off or auto shut down by low battery then holding vol up & power button screen on till phone off again then start phone again it will shows increased battery %
For eg using phone for 10 hrs with 1 hr screen on time it discharge 100 to 0% then I reset battery stats & start phone again it will shows 65% battery
2 nd thing if I'm charging phone it wether phone on or off (let's assume 35% ) it's % not increased but it shows phone using more power after some time it will shows less battery (15%)but in reality phone is charging after resetting battery stats with above method it will shows correct %(55%)
I tried these methods to correct it
Flash stock firmware again unsuccessful
Flash stock ruu again unsuccessful
Also tried vol up + vol down + power button holding for 2 minutes to battery stats reset
What I should do ?
I count manually battery life it's above 24 hr with screen on time of 2.5 hr

Did you re-downloaded your apps after flashing the ruu or you have tested the battery directly after flashing the ruu? (to make sure none of your apps or settings is draining the battery).

What about your apps? Like @alray asked. Have you tested with just the barebone stock rom with no apps installed?
I had a similar issue a while ago it turned out to be "Gsam Root companion" after removing the app my battery percentage returned to normal.

Err! Strange could be battery problem but it's weird how clearing stats cures it temporarily.
Have you tried resetting USB host mode with Vol up+down + power for 2 mins?
Maybe charge to 100% in all modes (on, off and in recovery) wipe stats reset USB host mode and reboot and monitor.

Whatever I do it always shows decreasing battery % but after battery stats reset it jumps to higher value
Even phone is off & put on charging battery shows decreasing trend but after reset shows correct %
Totally pissed off
This is latest drawing uhhh !!
I think your battery is going to die soon. Most likely some of its blocks are complitely dead, that's why it shows that kind of stats

Did you try to run your phone without rebooting to see how much it will last? Also, did you try another charger? Judging from your screenshots my guess is your battery is dying, but that would mean you couldn't get that much off charge and SOT to save your life. My battery is still pretty good, and I get just over 3 hours SOT and 36-48 hours off charge

ok let me explain screen shot
Anyhow I charged phone to 100% start it use it for 14-15 hr with 1-1.5 hr sot it goes to 0%
switched off or auto off
not charged
Battery stats reset with vol up + power button for 20 sec (it shows green HTC then goes off again)
Start phone again it shows 60% battery again (not charged )
Use 7-8 hrs with sot 1 hr approx
Goes to 0% again
Repeat process again shows battery 30-35% again
So this is screen shot history

I understood your screenshot. So, every time your phone shuts down, you do the reset thing, right? I would like to know what happens if you just try to turn on your phone after it shuts down. No reseting, no nothing. Simply try to turn it on

That's a lot like my old Xperia X1. Turned out it was charge regulator issue. You might want to look that up. If I remember correctly, Xperia had that regulator on its motherboard. I changed it and everything was fine after that. I think M7's charge regulator is in the battery, so we're back to faulty battery. But that's just my opinion, you might want to monitor charging current to see if your phone is getting correct charge current

I have 3 HTC phones in my family I use their charger randomly
My sister's HTC One m7 battery is fine no issues
I think my phones motherboard can have some issues as in warranty period it's battery changed 2 times so it could be !!
I got confused as after 1st battery replaced I hard brick phone & HTC changed motherboard after 2 months of that battery replaced again
Now I don't know what it is ?
I wish if battery is faulty it should dead asap so I can replace battery

Well, it could very well be motherboard issue too, but that was my last resort as it means you're pretty much screwed if your warranty expired
