Your phone has no battery. Let it fully charge.

once it is fully charged, calibrate the battery. what rom are you on?
No need for calibration. Im pretty sure its just no batteries and he forgot about it and thought he had juice left over. and its not a problem with any rom. or thats what i think ^^;

I have the exact same problem with my Nexus S4g, plus it will not charge and continues to stay at 0% with battery status being FULL.

Ok so I charged my phone up. When it said it was fully charged I took it off charger. It went to 98%. I then plugged it back in and waited till it said charged again. I repeated this for about 30-45 minutes and when I took it off it stayed on 100%. Its been maybe 30 minutes and its down to 99%. Weird eh?

thats whats called bump charging.
if you read the recalibration thread you'll see that what you did is similar to what you're supposed to do to recalibrate your battery.
This is how lithium ion batteries work. Keeping them at 100% actually shortens their life span. The android system tries to prevent it from charging to max for this reason. Unplugging and replugging in like you did tricks the battery into over charging. It won't causing damage once or twice, but try to not make a practice of it.
Wow,thanks for that. I was gonna do it everytime so thanks for the heads up

Yeah, bump charge a coupla times then clear battery stats from cwm. it will turn into the new 100%
Great advice guys, I had the same question, now I know, thanks

DigitalEagle is correct...Li-on batteries are very picky about overcharging
i made this post because people might be wondering about how to charge their phones.
(i say these things from experience so if different for anyone then let me know)
make it a habit not to charger until its at least 15% or less. i always charged my g1 and left it plugged in even at 100 and after weeks the battery life went to hell. i went through 3 batteries that way.
Also try not to use the phone while its charging. i cant really explain what the hell causes that but i know from experience of two other phones that the phone overheats and messes up the battery. so that means avoid over-night charging. i charge mine either before i go to sleep of first thing when i wake up.
also when ur charging ur phone, DO NOT put it under anything, like between a pillow the bed. ur phone will overheat like to the point of too hot to touch. also from experience.
Thanks man,that why my old battery started die'n so fast

I normally do this to calibrate battery:
1. Charge to 100 % with phone on
2. Unplug and turn off
3. Charge to 100% when off (i normally leave it for 10-15 minutes)
4. Then unplug, turn it on, then after fully booted turn it back off
5. put it back on charger till it fully charges again
6. boot into recovery and wipe battery stats
now use your phone as normally and give it 3-4 full charge cycles till the battery is properly calibrated.
Battery calibration is a app on the market. Check it out! It saves you from having to go into recovery and wiping battery stats

i follow all of this and i usually get around 20 hours of battery life. and ive only calibrated my battery once.
I heard that leaving the phone plugged in for a long time can affect the battery's performance. Is it bad for me to leave my phone plugged in for 24 hrs+?

keeping an li-ion battery fully charged all the time is not so good for it, not because it can become "overcharged" but because your not using the battery it may suffer from capacity loss, the ideal environment for the battery would be to let it discharge to about 50-20% then charge it again till full at least once in a while so that it is maintaining its cycles and capacity. :good:
OK thanks.

I always charge mine for a couple hours before I go to bed that way I don't leave it overcharging. Throw it in airplane mode and go to bed that way ur battery doesn't drain too much overnight.

Also is it bad for the battery if you reboot a lot?
Pretty sure the phone's charge circuit isn't going to do anything to damage the battery. Once it's charged, it may go to a tiny maintenance trickle charge, but you will be fine. Rebooting also will just drain your battery, not damage it, as it uses a lot of CPU and I/O to get Android fully up and running.

Not bad for the battery but I guess you'll have to charge it again sooner
Nice thread on Li-Ion batteries http://forum.xda-developers.com/showthread.php?t=669497
So on a daily basis I should run the battery down to about 20-40%, and then charge to 90-95%?

I run mine down to 5% and charge it to 100%
Sent from my HTC One S using xda premium
it cuts off when its fully charged so i wouldnt worry, also you dont have to cycle charge li ion battery's even if you only run it down to 60% and charge it, it wont do it any harm, infact they like to be charged willy nilly as its keeps the ions jumping about or something, haha
Still dealing with battery drain. I've gone back to stock, wiped data, basically everything but format external sd. Internal sd wiped. I can't get phone to charge. It connects to pc. Charge icon flashes like it's charging. LED charge lights up. Battery just slowly dies. I've tried that rescan media app. Doesn't help. Not sure what to do now. You think this will settle or is phone mechanically toast?

Plug it into the wall to charge. Also get better battery stats and see whats eating the battery.
