"battery full" - can it be overcharged? how to turn off beep?
My phone beeps and displays "battery full" when, you guessed it, the battery is fully charged. If I leave it charging (e.g. through the night), then it will keep beeping (not sure how frequently - perhaps every 30 mins?)
1. Can my N95 battery be overcharged, i.e. damaged by leaving it on charge for extended period (although typically not longer than 8 hours)?
2. Assuming it's not a problem leaving it charged... how can I stop it beeping to tell me the battery is full! It does this even when the phone is turned off (and charging).
You put it in silent mode, or disable warning tones? Perhaps even in the off state, it retains these settings for such alerts?
I just turned warning tones off - we'll see how that goes. 'Course what I really want to do is turn *just* the 'battery full' tones, as opposed to all warning tones...
I've found it depends what you're doing with the phone once charged:
If you're using wifi or 3G connections while its plugged in, it will use the battery and then start charging again and then obviously give you the alert once its finished charging.
With wifi and 3G off though, once the phone has charged, it doesn't beep again for me!

I have my charger plugged into an mains socket timer so that it doesn't start charging until 4am (when I'm asleep) and turns off at 6am (when I'm still asleep). Even if the battery is totally flat (I charge every night so it rarely is), 2 hours charging is sufficient and it minimizes the beeping.
Lgladdy's answer is 100% correct.
Stop anything which uses the battery extensively such as wi-fi, data, bluetooth etc.
Without these running it will trickle charge, and you'll only get the one warning tone about being fully charged.
Once the battery is recharged to full, will it continue to charge? Or will it sort of go on "standby mode"? Like when a laptop is 100% charged, it won't charge the battery anymore until it's being used.
Just want to know so I won't make the mistake of overcharging the battery, killing its life span quickly.
By the way, hi. I'm new.

As stated above, it depends on what you're doing when it is plugged in with a full battery. If you're running something power intensive (ie. use more power than what the trickle charging provides), then it will immediately start charging again. As soon as you stop using that much power (ie. idling in a web browser or something), the battery will reach 100% again, thus it will tell you you're full. When you load a new page, battery drops to 99.9% and start charging again... once you reach 100%, it'll tell you you're full again.
And the cycle goes on...
