My battery has been dying at 20-30% lately. I've done all the tests from cycling (letting it completely die, then charging to 100%), to battery calibrations, full restore, full system wipe in TWRP to the point where it says "no OS installed", and then flashing the stock rom.
After all this, in just the first try, the phone died at 30%! I turned the phone back on immediately and saw that it showed 3% remaining. I decided to leave the phone on and let it discharge on its own. After 24 hours, I was surprised to see that the phone was still on and at 1%! That's a 2% drop in 24 hours. I've attached the battery usage page for reference.
Can anybody explain what is going on here?? Is this a software or a battery issue? I'm left to thinking it's a battery issue after all of the tests that I've done. Whatever miscalibration it has should have been reset when doing a full wipe right?

It's a good app used to drain battery for cycling purposes.

This might have been answered somewhere, but i couldn't find.
My kaiser takes an hour atleast to get to 67% battery level on the power adaptor and as soon as it reaches that level it takes just 5 min to get to 100%. This is very strange. I performed a Radio upgrade to 1.70.19.09 a day before. But this is strange?
The battery status app starts with whopping +600mA of charging current on a 0% charge and drops to 100mA at 50% charged and to +53mA when it is around 67% and then in some time it says 100% with a charging current of +53mA.

Have you tried changing the radio back? To see if that affects anything?
Is your battery life normal? Does the same happen if you let the battery discharge once and charge it again? Changing the radio could have reset the battery meter calibration and it's just finding its way again.

Do you mean to say that i should give a few recharge cycles( a week may be) and this should be resolved?
Run the battery down completely once until the device turns off, that will also allow you to see if you have normal battery life, then recharge fully. Once is enough.

Doesnt work. I completely discharged my kaiser such that it switched off automatically. Recharged to 67% and then shortly 100%. i dont see 70-80-90% charges.
Once it switches off, remove the battery, wait 10 seconds, put it back in, turn on again. If the phone still says low batt and turns off again then your battery is really empty. If not the calibration is really off, run down again until it's really empty, then recharge without interruption until you get the green LED.
You didn't say if your battery life was normal.
same problem here
I have experienced the same issue. Battery is less than 60% and suddenly it reaches 100% (in a couple of minutes). My battery life seems actually very short to me but I must say I started using HSDPA the last week (my carrier finally offered it) and off course my battery lasts much less than before, so it could be just an impression. I flashed hyperdragon III Blackstone (nov 1st) last weekend and the radio is 1.65.24.36.
Just to give you an example, this morning I was listening to streaming radio over HSDPA and battery dropped from 100% to 40% in 50 minutes (screen was off all the time)
So I will try to empty my battery completely and charge it again. I´ll report after that.
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.
Is it true that the porcentage of battery u have when u flash ur phone is the one that will be used as the new 100% ? also whats the procedure i should use to erase the battery stats? my phone dies in like 4 hours , let it discharge, charge completely and then?
I don't think so, cause i always flash my MS anytime i wish even when the indicator show <20%, or when charging on UBS
I also never bothered to charge fully before flashing. Though I think resetting battery stats does help indeed.
i also read something similar to this, someone told me to charge to full, then let the phone discharge UNTIL IT TURNS OFF BY ITSELF (=battery completely dead), then charge to full again and then delete the file batterystats.bin in /data/system folder (root required).
i suppose this is what you are talking about?
i will try this in a few hours (currently discharging the last % of my battery).

What's your ROM?
On froyomod do you have option to calibrate battery and wipe battery status
Well, I've flashed it to FroyoRom with approx. 40% charge, played around a little, the next day when I was normally using it and my battery went down to 30% I deleted the battery stats, the system rebooted and voilla, I was at 50%
I don't know about this full charge - discharge - full charge - delete stats version. I guess I'll try it on an occasion and see what happens. At this moment I'm at 90% after being disconnected from charger for 5 hrs, though I wasn't using the phone much during this time.
...and currently finishing the same charge - after 1 day and 17 hrs currently at 20%. My Milestone never made it through the day without having to charge it through the night. Love it
The FroyoMod is really the best at the moment...
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 )
Click to expand...

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

Hey all,
I have had terrible misfortune in the realm of battery stats. Ever since CM7 (and maybe even before) my phone is unable to figure out how much battery is left. Here is a common scenario:
Charge phone overnight, use phone throughout day, battery dies after 6-7 hours of moderate-heavy usage. I plug it in, reboot, and then it reports ~60% battery left.
Another common scenario is that it will dwindle around 5% battery or less and go up and down until it finally dies.
I know that this is a misreading of the battery and not battery drain or a rogue app because when I flash a new ROM the battery life is amazing for 1 day. The day after I flashed Team Hacksung's ICS rom, I got almost 17 hours of battery life with 2.75 hours of the display being on and 30 minutes of Google Music. I was blown away! But even then it was dwindling around 5% not knowing when it would actually run out. The day after, it was back to its old tricks of misreporting the battery percentage.
Today I charged it to 100%, unplugged it, and shut it off. Then I plugged it in while it was off and let it charge to 100% again and wiped battery stats in Clockwork mod. I'm getting ok-ish battery with that, but it's not even close to how good it was when I first flashed ICS.
Anyone have any ideas what I could try?
Thanks!
When you wiped the battery stats did you let the battery fully discharge and shut off before charging again?
After wiping battery stats it is recommended to let the phone fully discharge to the point where it will automatically shut off.
Keep in mind with the age of our phones, it could just mean your battery is dying. Try the above method, but in my experience uncalibrated battery only last a few days. The phone will "fix" it by itself the longer you use it.

That's what I'm doing currently. Battery life seems improved, but we'll see what happens. It's nearing death now, ~6%. At this point it will probably misreport it for a few hours until it finally dies. I left it unplugged overnight, so now it's at 19.5 hours uptime with 1.75 hours display time.
Definitely improving! I hope that it successfully recalibrates.
Battery stats have nothing to do with how the os calculates remaining battery...they are what is displayed in settings>about phone> battery use and are reset each time you charge to full.
You're just giving it a good bump charge...wiping the stats is just a placebo effect.

Seriously? Wow I didn't know that. Is there a way to actually reset how the OS calculates the battery?
Does this app do anything?
https://market.android.com/details?...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
Nope...that app is just perpetuating the myth of what the batterystats.bin file does.
Don't hate me for this but, Then how come Roms usually give me better battery life after a full cycle? not bump charging or deleting battery.bin just running it?
Because the system for tracking the remaining power is getting to know your battery. once it gets a feel for it, it's more accurate. In theory anyway
So the "give it a day" is still true, at least in theory?
Sure

battery gauge temporarily fixed by removal and replacement of battery
Ever since I rooted my phone, I've noticed that the battery gauge/meter is way off. I keep an eye on the charging voltage and try to pull the plug around 3.92 volts. Problem is, the gauge is always reading low until I pull the battery, wait a few minutes, and then reinsert and boot up. Then it's fine for a while, but I notice it creeping down even though I keep topping it off with a charge to keep it around 3.92 volts.
What's going on? Do I have to fully deplete the battery and charge to full to have an accurate (or somewhat accurate) battery gauge? Do I have a bad battery (this battery has been used only a couple months)? Is something else going on here? Recommendations, studacris? Doesn't the os use battery voltage to calculate state of charge (%)?
