Help Galaxy S charge time and battery usage

I charge mine overnight everyday. its probably soaking for 4 hours. Lasts easily the next day for what i want.
I find if i take it off charge at 100% if in a hurry to take phone somewhere it'll drain really fast..
Best thing i did was root it and tune the CPU so that in screen lock state the battery use is 'extreme power save' and not the default (power save or normal? dunno)

Mine takes about 3-4 hours from empty to full.

However, my battery drain is exactly the same when I'm watching youtube videos/playing games/listening to music/browsing/getting texts + phonecalls all day as when the phone's in standby all day doing virtually nothing.

I've checked the task manager to make sure no processes are running and using up the battery. I'm at a loss as to why the battery drain is the same no matter what the usage.

Obviously Wifi, bluetooth, gps etc are turned off whenever they're not needed.

This is exactly what i was referring to in my post above yours. Root and tune the CPU (with CPU Tuner app) and this will change big time!

I find when I take my phone off charge and the status screen says 100%, I remove the lead and can literally see the percentage go from saying "100% Fully Charged" to like 97% or something =\ only had the phone a month

I've found the exact same thing happens to me too when I switch off the plug it will drop to 99-98%. Ive had mine for a few months now but I'm hoping that Gingerbread will help fix it.

its annoying, ive got nothing running out of the ordinary to make it do this, I've only had the phone a month or so and it never used to do it when i first got it....

The battery immediately drops to 98% after unplugging the charger because it was never charged to 100% in the first place. The battery meter is actually lying to us. It's not a bug though as it's designed to protect the battery from being overcharged as doing so will result in the battery having a shorter life span.
If your phone is rooted, you can calibrate the battery to allow it to fully charge to 100%. Download an app from the market called Battery Calibration.


Cheers.

For the people who say that their phones drop instantly when they unplug their phone.

Mine was doing the same....so, once I unplugged it and noticed, I decided to plug it back in in. And then I would leave it for about 10 mins and unplug it to see....then it would drop a few percent again, but not the same as the first time....So, I kept doing this until once I unplugged the battery, it didn't drop at all......stayed at 100%

That's when I downloaded Battery Calibration and reset the battery stats with that app.
Went from quickly losing battery 8-9 hours of usage, all the way to 30+ hours of usage.
