Get a good 2 Amp AC charger and leave on on charge for a good while.

After able to boot, you 'might' require a battery scaling calibration. I have posted a guide in General section for that (link in signature).

Best of luck

If you're referring to your problem posted here, I guess the
Quote:

Don't let the battery discharge completely : potential to damage the battery and/or the battery fall "asleep" (internal safety circuit opens) with the charger then unable to service the battery.

.

A good 2 Amp AC charger can often "kick-start" the dead battery, but not always.

As far as the cause, I can only guess; app or process causing wake-lock > battery drain, or perhaps a battery scaling issue as I described in my thread : [TWEAK] SGT 7.7 Battery Calibration [Fuel Gauge Reset]

My tab would discharge to approx 30-35% then drop to around 10-11% almost instantaneously, sometimes shutting off if I wasn't paying close attention !

Glad it's sorted

I'm not 100% sure of all your details, but sounds like the battery has an issue and starting to die.........

I would :
1. Flash all to completely stock firmware and kernel (to rule anything out)
2. Turn device off and leave off
3. Leave on AC charge overnight
4. Once fully charged, use as stock for a while. Battery will re-calibrate itself after a few charge cycles (if it's ok)
