As written in topic, phone boots when usb plugged in. Cant charge for battery calibration.
Using magldr, cwm, hyperdroid cm7.
Sent from my HD2 using XDA App
phone cannot charge when powered off when magldr is installed.
magldr starts the phone when it detects power so that charging can start.
That is a Magldr feature.
It boots the phone so it charges. CLK will go into a charging only mode.
Just let it charge all the way to 100% and look in the hyperdroid thread for more details on the battery calibration.
So no way to charge when magldr is installed?
Thx sofar!
Is it kernel specific how to calibrate then?

Nope, no way to charge when phone is off unless using CLK (or SD Android of course). Not kernel related as far as I know and I was wondering about the battery calibration as well. Maybe it will work with the phone on as well?
Well, best way I found is recharge when in Android, unplug, switch off, plug, charge until full again, reboot. This will overwrite Android setting for max capacity.
I dont want to set the values manual, cause u never know what cap.the new battery really has.

get into recovery and try a cache wipe to start. if that doesn't work, do a factory reset. have you backed up your apps or anything? doing a factory reset will wipe your data and you'll lose all apps, settings, everything, but it will take the tab back to "out-of-the-box" setup.

What happened to cause this? Did you let it drain down to zero? Did it go from 50% to 0% at once?
More details please on what led you to this point.

Plug into wall charger, turn tablet off, let it charge for an hour and see if it boots back up.
Not USB, to weak.
And......you really should know better then to root and do intensive tasks with 13% battery. Just saying.

warrant replacement. call where you got it(google play, asus, other) and get a replacement. its a known issue. i had my replaced last month(google play store) because it stopped charging. they didnt give me a hastle, and sent a replacement out fast.
Have the same problem, battery is working good but looks likes battery sensor malfunction, so system doesn't know battery status!.
Don't know what is the effect of that for the battery life!.
Tried every thing to fix that.
Any way, the only solution is RMA, already called Google, and they agreed for a replacement.
So, don't wait, you got 15 days since you got it for a replacement.

I had this problem when I had the latest bootloader installed on my device, everytime I tried to charge it from (what it thought was) 0% the tablet would turn on and instantly turn off again because it had 0%.
I somehow managed to get it into fastboot and loaded the older bootloader (the one which won't let you into recovery without being connected to USB) and the tablet began to charge without turning itself on!
I left it to charge for about 2 hours, turned it on and it had enough juice in it to stay turned on and charge the rest of the way to 100%.
Not sure what the reason / cause of this was, my battery was at about 10% before it happened and it suddenly depleted to 0%!
Hope this helps!

can you link the original bootloader you have used?
Factory reset just wipes data.. probably not his data

my situation is different here, like this, I got my shipment at work, open the box, turned on the device, it's like 40%.
test it then put on the table for charge, take a look was in 98%..... after half hour it's 0% with on red battery icon.
Now sometimes battery work and I can see the "xx%", sometimes it stayed at 61% for 1 hour of use then jump to 42%!!
Sure something wrong with the battery sensor!.
This is a classic example what happens when people don't take the time to educate themselves on rooting their device. Anyone who owns a nexus device should know where to find factory images for both old and new firmware. And I always charge via USB and not AC. AC overheats my battery way too much. It can cause serious damage to your device.
Just saying
when i charge it goes 90% in few seconds when i unplug the charger it goes to 5% in few sec then it shutdowns..
i tried to flash stock rom but no help..
what should i do..?
busted battery? how old is it?

I had this. It was not the battery. I replaced it. Wiped battery stats. When you charge does it keep stopping charging?

I have a similar problem
My battery was getting bad for a while, so I bought a new one off Amazon USA (I hope it's real). However since I put the new battery in my phone and switched to CyanMobile, my battery has been all over the place.
I can't get through a 9 hour work shift on 2G speeds (where I may glance at my phone 2 or 3 times). As well as the battery running down quickly, it'll jump from say 80% to 60% or 50% to 30%.
It does this both when charging and discharging. i.e. the phone just died. I plug it in to charge whilst switched off, and the screen immediately shows 20% charge. I turn it on whilst plugged in, and by the time it boots up it shows 60%!
I've tried deleting battery stats in recovery mode, and using a battery calibration app from the market...but nothing
What to do?
Please help, when i was flashing awesome beats, at the end of flashing my device's temperature is very high and then it turned off by itself. After that, my device wont turn on when i pressed the power button although my battery shows 50%+ before flashing.
I tried to plug the charge and the white battery charging indicators appeared but then the device went off again after a while. It happens repetitively, white battery charging shows up, and then turned off. When i tried to turn on the device while plugged into charger, a google logo appeared and then turned off. I can access the bootloader when pressing the vol down button while it's charging. Please help me, what's happening with my device? is it because the battery is fully depleted or maybe another issue? Thank you
Sorry for my bad language.

i've tried to flash the factory image but the problem still there. it wont turn on with charger unplugged, when it plugged, white battery charging indicator shows up, and then turned off with red led blink, after a while it turned on again with white battery charging indicator and again it turned off with red led blink, this happened repetitively. If i put my device in charge for a while, the red led wont blink again when it turned off after the white battery charging indicator, but it still wont boot..

Let it charge for couple hours before doing anything to it. How are you flashing the factory image? I recommend using one of the toolkit to guide you through.

Sometimes old school works.
Pull the battery and put it back in after 15 seconds

Thanks for all of your advices, i think i've already fix my phone since it can boot again and i successfully restore my nandroid backup. I did charge my device using 3rd party charger with 2.0A for a couple minutes and then unplug it and charge using my original charger. and guess what.. it works hhe. Thank you all :good:
Glad its alive again. Next time make sure to feed it well. Don't let the battery die to 0%. Recharge it once u reach 5% to 10%.

Thanks btw. the weird thing is, when i turned on the device, the battery is the same as just before it turned off. I think the battery is not depleted to 0%, maybe the device is malfunctioning or something.

hmm that is weird. Did you try wiping battery stats? If not, give it a try.
I was running CleanROM (doubt it has anything to do with it). Woke up this morning, phone was working fine. During my first break at work, it was off. Tried turning it on but it goes through the LG splashcreen, then the blue loading circle. Came back home and it doesn't charge. Stuck at 0%.
Made a nandroid backup earlier so I factory reset it. I am able to turn it on once in a while and checked the battery settings, it says needs more time to collect battery usage. Still the phone is stuck at 0%.
Hoping anyone has a fix/answer. TIA
Plug it into a wall outlet. Leave it alone for an hour or so . Give it time to charge up

I left it there for 2 hours, still 0. When I use the phone (While plugged in) it works fine. Unplug it, turns off immediately. It doesn't do that when I'm in recovery.
I formatted data in recovery, still getting the same results. I'm trying to unroot and bring it back to stock but I'm having problems with my PC atm.
Battery stats
Hi!
Did you already try wiping battery stats partition?

I remember that on CWM, but I'm on TWRP. I don't think I've seen that option.
Deleted battery stats, still stuck on 0%. I even switched ROMs from nanadroid to see, no changes.
Phone turned on this morning. Risked taking it out with me for work. The problem now is that the battery was stuck at 100%. After 10 hours of usage and wake an hour on screen time. That's not normal.

How did you solve the problem then?
i have samsung note 10.1 same issue stuck at 0% only
how did you get to 100%
its better than stuck at 0% coz i cant use it when unplug on the charger
