Galaxy S3 Battery Info Required

[defected]

Hi guys, got my S3 2 days ago and I'm over the moon with it, feels like such an upgrade from my Desire.

Anyway, got a few questions about the battery life, it's not a rant, just looking for some info.

My battery hasn't been great so far, however I've been using the hell out of it and working it hard so not complaining, but this is where I started to get confused.

I figured I'd get better battery life if I completely drained it and then fully charged it. Basically, the battery drops quite dramatically at the moment, so I get to 10% and think right, I'm going to drain it and leave it overnight. As soon as it went into power saver mode it's taking me FOREVER to drain, since it hit 5% I've lost about 1% in over an hour, I've constantly recorded a video, I've played videos, played games and the darn thing just won't end! I even have bluetooth, wifi, GPS everything on!

Now, is this because my battery is new and it's not calibrated properly so there's more juice left in it at the end than it thinks there is meaning what it's telling me is not correct?

OR

Is the power saver mode REALLY this good to the extent it can handle me doing anything I throw at it? (For quite literally hours?!)

OR

Has power saving turned off something that is dramatically hogging my battery at the moment that I'm not aware of?

Any help is appreciated as if I could normally lose 1% during over an hour of having everything on and trying to abuse the battery as much as I possibly can it'd be rather amazing!

Cheers folks!

Noone?

I think you are the first person to ever come on here and complain that you can't drain your phone. Anyway. Maybe its the way the phone works. It extends the life at the end so when your phone is dying and your in a pinch it will last longer. Giving you time to get to a charger. That is just my two sense. Just keep using until it dies.

By extends ( I mean) , maybe it actually has more juice then the battery indicator shows.

I would speculate it is just a mis-calibrated sensor (for reading the power level). Try and drain it again, and see if the phenomenon repeats itself, my guess is it won't.

FWIW, I don't think you need to "train" the battery like back in the day. I've read here that Li-Ion batteries don't need this, unlike old RC car batteries. But a sensor error like you described is pretty annoying, so maybe the training will correct this problem.

You really should only need to drain the battery 1 time in an attempt to fix this calibration error as draining Li-ion batteries reduces their capacity each time. Other than that these batteries like maintaining a partial charge at all times.

Thanks guys, all useful responses.

I let the battery go to 2% then I needed to go to bed (it literally lasted 2+ hours of doing absolutely everything I could find at the same time and only lost 3%!

I fully charged it for 12 hours (weirdly though when I take the phone off charge after that long it's always on 99%, I've never seen it on 100%).

I now have a software update available, so hopefully the update along with the battery drain will cure my problems!
