You should research on google on how to "condition" your battery. People say to let your phone fully die when you get it, then once it is dead.. charge it for about 8 hours or so, and repeat this like 3-4 times. This supposedly helps you get the most outta your battery. So bascially do the following.

1. Kill your battery when you first get the phone, let it die completely.
2. Dont turn it on, hook it up to your charger, then it charge for 8 hours or so.
3. Use your phone till it completely dies again.
4. Do step 2 and 3, about 3-4 times.

You dont need to follow the 8hr charge. Just charge it until its full. The timed charge is only for the old batteries which had memory effects and such, and not relevant on new battery technology.

As for knowing when its fully charged, it will beep once it is, and you will have a battery icon with "100" on it on your notification bar. The phone will automatically stop charging. But once battery level goes below 97%, it will start charging again.

Veddy eenterestink. My battery isn’t new, but was never “conditioned” in its infancy. I suppose I could do that now if I pull the SD and backup, do the deed, then restore and remount the SD?

I understood the days of battery memory (NiCad) had long since gone and that 'plastic' type lithiums can be charged during any period without it remembering. And as already stated, the Green battery icon appears top left and it beeps.

You don't need to 'condition' your battery. just plug it in when you think you need to, it will beep once it's full.

True... you will get a notification on left side of notification bar with battery symbol containing "100%" in it once battery is completely 100% charged...

Does Battery Calibration, which also requires a complete drain and charge, do anything?

Yes, it deletes the batterystats.bin file which gives your phone a rough estimate of what a full charge is. Charge till full (the app will beep), then hit calibrate, unplug and let your phone die. The batterystats.bin will be recreated once your phone turns on/dies, I can't remember which.

You need root for the app to work though.

Thanks, but are you sure of that? I’m asking because neither the market nor the dev site mentions that word, far as I can see.

Task killers are pretty bad for Android and conflict with the OS's own task management capabilities so it would be a good idea to uninstall that to start off with.

Also, some phones are hard coded to report a full charge before they're actually fully charged. This can extend the life of the battery as the lithium ion batteries in modern phones don't really like full charge/discharge cycles. Also, full is an estimate so when off it might give one value, but when turned on, it will report another.

It's not unusual and happens on my handset a fair bit.

It's not a problem per sť, it's just a quirk of the way your phone works.

If you charge the phone whilst switched on, it would probably get to 100%.
