[Q] battery mV left when dead? - Atrix 4G Q&A, Help & Troubleshooting

My phone has 5% battery left yet the battery calibration app is showing 3494 mV left. Is this correct? I would think that when the battery is dying there would be 0 mV left, but maybe I am wrong. Can anybody tell me if my phone is messed up? I'm running unlocked stock rom with kholk's 1.2 ghz over clock kernel
Thanks in advance

This is fine for lithium batteries usually 2.5-3.5mV is left in each cell so that the battery maintains its efficiency... someone please correct me if I'm wrong

Mine is about the same. I was also wondering the same thing but I'm sure that it is normal.

[Q] Battery reading issue

I've had my ATRIX for about a month now and I haven't seen this yet. I'm rooted and unlocked running CherryPi v0.5a. My issue is the battery is showing 95% but the phone says it is fully charged. I'm guessing this is just an issue with the ROM itself but I'm not certain. Has anyone else experienced this issue?
It has been said elsewhere that this is just a battery calibration issue. Try wiping your battery stats in CWM after a full night's charge. Let us (namely the people in the Cherry thread) how it goes. Don't forget the thanks button

You need to try recalibrating your battery as per instructions i posted here:
http://forum.xda-developers.com/showthread.php?t=1198333
I followed the calibrating tutorial and at 95% battery the calibrator is reading 4200mV. I haven't finished all the steps yet. I will +1 both of you when I can on my computer or when I find out how using the XDA app.

4200 mv is full charge, so you battery is not the problem.
If you leave it on charging once it says "phone charged" it will eventually get to a 100%, though it's not nessecary.
The battery meter isn't 100% accurate:

Alright thanks for your help. I let it sit for awhile and it says its 100% charged and the voltage is 4203mV.

BATTERY CALIBRATION mV

If you use Battery Calibration how many mV do you have at 100% and what rom are you using i used to have 4242mV
now i have 4190mV on trigger redux what do you have im thinking i may need a new battery
4185mV @ 100% - Although I will say that my battery has been all over the place lately. If I unplug it now even though its at 100% it will drop 4-5% immediately. Just saying. Hope this helps
*Current setup is in signature*
Ok that similar to what I'm getting

Have you calibrated your battery (cleared battery stats)?
I always use BatteryCalibration app from the Market after flashing a new ROM.
Otherwise the system needs to adapt the correct battery power to the old stats which may differ from the values in the new ROM.
BTW, I just flashed a new ROM yesterday, discharged my phone down to 12%, then fully charged the battery up to 100%, started BatteryCalibration app, hit the calibrate button, disconnected the power cable and turned the phone off last night.
This morning, the battery indicator showed exactly 1% less than yesterday evening.
I think that's Ok.

Battery Lost 40%

So I was overclocking my Atrix 4g and benching it using Faux123's 1.45 Ghz kernel. CF Bench caused it to overheat and restart every time so I did the stupid task of putting it in the freezer (Yes the thing on top of a Refrigerator). And I didn't just put it in the freezer I put it near the part where the fan blows in the cold air. Apparently that wasn't a good idea since my phone suddenly Jumped from 60% battery to 19%. Basically loosing 40% of its charge. Followed by a FC and Reboot.
That night I wen't to sleep and plugged it into an AC charger, it was charging for about 12+ hours. And now my phone won't charge over 60% (Kind of makes sense with the 40% battery loss) and wont go past 1109 mAh ( it's a 1930 mAh battery).
My question is: Have I ****ed up 40% of my battery forever or this something that can be fixed. Note: I have already tried wiping the battery stats.
Try to take out your battery and plug your phone into a wall charger, after that place your battery back into your phone and let it charge

Thanks for the reply.
Should I wait until it has drained or not?
Shouldn't make a difference

If that doesn't work, try recalibrating the battery...
