This happened after I installed android 4.2.2 ,my battery status icon turned gray, and brightness icon turned gray, and only displays a question mark. When I go to battery status in the settings menu it reads unkown. I just got home to plug it into the charger but it will not charge, I have also done a battery pull.
Thanks
have you got the solution for this problem.
do you found a solution for your problem. my note 8 n5100 doesnt show charging status in any place. it can charge buat at veeeerrrrryyy slow rate. it takes about one day to full if i switch it off. i try to use app battery calibration but it said that i have no batterystats.bin. i did found batterystats.bin in /data/system. i succesfully deleted it but nothing happened. no change. need help.

I have an odd issue. I am running the stock ATT rom until I can get the stupid phone to take the HardSPL (different issue being worked on).
The icon at the top shows the battery at full capacitiy all the time. I have Phone alarm on and it has a battery indicator that shows it as low as 20% while battery icon is still 4 bars full. Also there are times when I remove it from the usb and the charging icon stays on instead of showing the battery icon. If I soft reset then it seems to go to normal and the charging icon is replaced by battery which seems to always show full.
I am quickly getting frustrated at this ATT rom. My Kaiser was set up perfectly for my liking and I want to get this to the same point.
Hi Guys,
i just woke up and noticed that my Desire was off. I usually connect the to the charger before i go to bett, so last night.
I tried turning the phone on but it didnt work on the first try. I pulled the battery and sd card and tried it again after a minute and the phone booted.
Now its running but the battery information screen says 0% and the icon in the notification bar doesnt grow.
Did a battery information wipe from Clockwork Mod - no changes.
Any ideas?
sorry for bad english...

Apologies for another not charging thread, i have tried searching for a similar issue but no luck.
I put my DHD to charge as usual last night at around 40%, the charge LED lit up and the battery icon was showing that i am charging.
When i woke this morning, the charge LED and battery icon were still showing that i should be charging yet the phone now only has 33% battery, so clearly hadnt charged. I checked current widget and when the LED and icon show charging i only seem to be getting anywhere between a reading of 40mA and 270mA. With an occasional 300-400mA reading.
I seem to be able to intermittently get the phone to charge and the batt icon to rise by a percent or two but then it seems to stop again. As i am in work at the moment i am having to charge via USB from my PC. Therefore i am currently unable to try another micro USB charger and see if it is indeed the charger or the phone.
Has anyone else had a similar issue, says it charging but it not??
Or anyone have any ideas of a solution??
If it matters i am currently using LeeDrOiD HD V3.3.1 GB. Id rather not have to return it to HTC as i am unsure of how to return the phone to default easily so it could be repaired on warranty.
Thanks in advance,
James
Firstly, download CurrentWidget, set refresh to 15 seconds, and make sure you set it to display battery voltage. If it is showing around 4200mV, it is charged, and you have a problem with the battery gauge.
To double check, turn off your phone, and see if the light goes green at 100%.
Boot back up, just to see if a reset fixes it.
If not, reboot into recovery, and wipe battery stats (or do it properly, turn off, wait until light is green, wait another hour, then boot into recovery and wipe battery stats).
Turn back on, and see if the problem is sorted.

Hi
I am running my Nexus with the bootloader unlocked, rooted using superboot and running francisco kernel.
1. I let my device run its battery down so it turned itself off.
2 .I then left it turned off and connected the charger. The Battery icon appeared with the lightning bolt. About 15 mins later I tried to turn the device on (still showing the Battery with Lightning bolt), it wouldn't turn on.
3. I disconnected the charger and the battery with the lightning stayed on the screen. The device still wouldn't turn on.
4. I then pulled the battery, which removed the battery icon, replaced the battery and repeated step 2 & 3 again. The same result occurred.
5. I then pulled and replaced the battery and turned the device on without the charger. The device turned on and had 15% charge. I have now connected the charger and am charging it with Android running.
Is this normal behaviour? It just seemed a bit strange to me?
Cheers
Stewart
From what I've read elsewhere, the offline charging issue is related to the installation of CWM, and it's being looked into.

Calibrating the battery on Android devices
Method for rooted devices:
1. Discharge your phone fully until it turns itself off.
2. Turn it on and let it turn off again.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
6. Unplug your phone and reboot. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7. You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
8. Now, install the Battery Calibration app attached below and, before you launch it, make sure your battery is at 100 percent again, then reboot.
9. Immediately launch the app and recalibrate your battery stats.
10. Once you've calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
11. Fully charge the battery one more time without interruption while it's switched off, and the Android system's battery percentage will be reset.
Note that all the app does is wipe the accumulated data from the batterystats.bin file giving you a new clean slate to work with. This method is also called, "training the battery" and should be performed infrequently. Maybe once every four months or so.

I ll give it a try
I would also note that this would be good to do right before installing a battery monitor app like Gsam or BBS. :good:

I haven't calibrated mine in a long time. Getting ready to do it right now.
How successful was this calibration?
