After calibrating my battery of my US WiFi Xoom(MZ604), the battery meter is stuck at 100%. I left it overnight with Wifi and the works on, but it's stilll stuck at 100%. However, the voltage did go down from 8000+ to 7000+. In addition, when I go to the battery uses page, it shows my Xoom being unplugged for 9h23min, battery at 100% all the way. When I enter the graph, the graph shows only 0s(as in zero seconds).
What is the issue? When I calibrated the battery by removing the battery stats.bin, did the system fail to regenerate it? If so, can someone pass me their batterystats.bin file?
I tried a Nandroid to no avail.
Thanks in advance and sorry if this issue has been raised before!

Sorry, fixed it already. For users running into the same issue: Nandroid, charge to green led(not 100%! green LED!) boot into recovery to wipe, then format cache.
My Xoom got stuck in 100% like this today.
But, if someone else have the problem, I could fix it without the full wipe.
The steps:
1. Shutdown the Xoom and charge until the LED turns green.
2. With it still plugged to the charger, open ROM Manager
3. Select "Reboot Into Recovery"
4. Select "Advanced"
5. Select "Wipe Battery Stats"
6. Select "Go Back"
7. Select "Reboot"
8. After the boot is complete, unplug the XOOM
9. Use it normally until it diischarges completely (auto shutdown)
10. Charge again to 100%, without interruption.
11. Battery stats should be ok now.

I have NOT tried it myself and so if it works do let people know.
I'm putting it in DEV section since it is recommended to be done before every new ROM installation. If the MODS think otherwise please move it to General section.
Here are the steps:
zeppelinrox said:
1. While in Android, charge up to 100% and leave the phone plugged in.
2. Delete /data/system/batterystats.bin
3. Remove back cover
4. Press Power and choose to reboot normally.
5. When the screen goes black and the lights go out, pull out the battery before you get the M logo. It will probably still work after the M logo shows up but that's how I do it.
6. Surprise: The phone will boot up without the battery! - Mine does - every time
Note: Batterystats.bin is recreated when you see the M logo - even though the battery isn't in the phone.
Go to Step 8 if the phone booted up as described.
7. If it doesn't boot up and you see the battery with the ?
..........a) Put the battery back in (you will see 60%),
..........b) Power off the phone (press power until LED light goes out)
..........c) Power on the phone (press power until you see the M logo)
..........d) Remove battery... and watch bootanimation...
8. a) After the surprise of seeing the boot animation without a battery, you will then see the lock screen along with a "No SIM card error" and no signal.
...... Put the battery back in - the SIM card error will disappear, you will get a signal, it will show 60% full and the icon will show the battery charging.
...... Go to Step 9 if this works as planned. If it doesn't, reboot (again without the battery) and use step 8b instead of step 8a.
... b) Put the battery back in during the bootanimation, but after the haptic feedback/vibration (and the buttons along the bottom light up).
....... On a normal reboot, you can actually slide and unlock the phone when you get the vibration during the boot animation. You knew that, right?
9. Use your phone normally while you calibrate the battery
10. Let it fill it up to 100% + 15 minutes or so. When it is truly finished charging, the battery should be cool.
11. If the phone is running hot, weird things can happen. For example, you may get no signal when you put the battery back in or the battery doesn't begin charging (the status bar battery icon doesn't change). Just let the phone cool off and it should work next time.

Somehow my battery went directly from 30 something into 5%, and suddenly drop to 4,3,2,1 and it turns of itself...
So... When i'm charging it, it's shown "Battery is too Low" screen, and when i'm press the power button, it says 31%....
What should i do to fix it?
Am i need to re-calibrate my battery, changing rom, or am i going to need a new battery?
Anyway, i'm using Unofficial Blisspop ROM
Phone is Moto X 1st gen that had the original battery and was slowly dying so I bought a replacement off Amazon and swapped it out. Now it doesn't recognize any charge level to the device. I've tried a couple of those battery recalibration apps off the App Store but no luck with that (though one of them tested the battery integrity and confirmed it's not a dud). When I swapped out the old battery it was at like 18% or something so upon putting the new one in and rebooting it stuck with that 18%. I read that you could retrain it by letting it drain completely then charging full so that's what I tried next, now it reads zero.
Here's the behavior I see:
Power off device, plugged in to charger. If you push power button it will display a battery icon with a question mark in the middle
Hold down power button in this state and it still doesn't start up but the battery icon switches to the standard lightning bolt 'charging' icon but reads 0%. This number doesn't change.
Hold down power button again and it boots successfully but battery meter reads 0% - charging (actually one of the recalibrate apps I ran set it to 4% so now it says that)
How do I fix this?
Plz sugeest me how to go about this.
I recently looking into one app and the phone restarted with white screen with bright keys. Screen is not displaying anything.
Plz help me.
I pressed power key for more than 2 mins, it is not even restarting ...

explain the current condition of your device, is it charged? how much battery do you think it have?
Here are some simple steps you can try:
1. leave the device as is(if it is ON) or use it as much as you can till it's battery drains properly and shuts down on its own.
2. try to turn it ON by holding the power button.
3. if it turns ON, use it till it is not able to turn on(0% battery).
4. plug the charger in and see how it behaves.
5. if its charging, then let it charge to 20-30 percent and then reboot to recovery,
6. Reset your device(wipe data).
7. if it is not charging, then its a hardware issue, can be on charger's part, or in phone itself, try a new charger that is known to work.
8. if its not the charger, I'm afraid you'd need to get it checked by some repair person.

Hello
i just calibrated the battery with "advanced battery calibrator" app. in the begning of the process it noticed that do not turn on phone unless the fully charged. i turned off the phone but it automatically turned on; i calibrated with that software again and turned it off, but it automatically turned on again. i turned it off and; after fully charged i wanted to turn on the phone: but the phone so quickly turn on & off. the LG logo just blinking. when i attach the charger it turn on and i can use the phone and it show correct percent of battery. but when i remove the charger cable, it turn off after 10 second. i upgrade its rom but still the problem exists.
can anybody help me?

My guess would be your battery is bad. I've had my device since launch and have gone through 4 batteries. Each time at failure the symptoms were the same. Battery drains fast, device shuts down with random amount of battery percentage remaining then bootloops and eventually only functions when a charger is plugged in. I'm guessing you were having battery issues intially and that's why you decided to use a calibrator? The calibration process may have been the last straw and your battery is shot.
