Battery life

[rat1983]

Actually, Li-Ion batteries have an average life of about 2 years. It's not because of memory effect so it can't be reversed. I'd say it's time for a new battery.

How much time the charge should last depends on how much you use it and what for. I say it's fine as long as it lasts until the next time you can charge it — I charge it overnight daily.

Charge-discharge cycles don't do any good to Li-Ion batteries, in fact it kinda hurts it to be below 30%. However it helps the calibration, so the accuracy increases and it seems to hold charge better.

Oh, and this life of about 2 years starts from the moment the battery is made at the factory, not the first charge, so try to avoid any new-old-stock or almost-new ones.

you are right, li-oins don't suffer from memory effect, so dischrage-fullcharge doesn't help, i do that all the time.

ni-cd batteries suffer from memory effect

and i charge the phone overnight every time
