So I unplug my N85 from the wall, completely charged (battery indicator shows 7 bars). I go out for a couple of hours, in which I use Maps and Music Player a bit. When I get back home and get ready for bed, the battery indicator still shows 7 bars (again, as expected, since I had not really used it much).
Now here's the shocker: in the morning, I look at the phone, and it's dead. There isn't even enough energy in the battery to start the phone for a few seconds, when I press the Power button. Needless to say, I did not leave any power-hungry application to run overnight...
Has anyone had this happened on their phone? Do these "sudden deaths" just sometime happen, or is it an indication that this (almost new!) battery is heading south?
I have this both my N95 and N85 😡 I think it's just a (bad) characteristic of the phones. As soon as you drop 2 bars then basically it's on it's last legs!!! :tongue:
The procedure I use with succes : drain battery completely - in your case no problem - put it on the charger for many hours , like > 12 hr , while the Phone is OFF .
Repeat this 1 or 2 times .
Regular however for Lithium batteries it's advised : do'nt drain to empty to often . Better to charge it halfway empty or the likes .

What's the network reception like in the area around your home?
If you have intermittent reception, or if you live in a 2G only area, the handset will repeatedly scan for a 3G transmitter, draining the battery in around 8 hours.
If you don't need to be contactable when you sleep, then use the offline profile.
If you live in a 2G only area, then you can set the phone to 2G only, to stop it searching for a 3G transmitter.
Hope this helps.
P.S. Regardless of all the above, the simplest solution is to charge the handset every night whilst you sleep.
As mentioned previously, Li-ion batteries have a longer life-span if you keep them charged as much as possible.
Allowing Li-ion batteries to drain flat regularly is known to significantly shorter their useful life.
Hi, thanks for your reply. I live in a good, 3G reception area, I don't think this is what caused the battery to discharge unexpectedly. And it hasn't happened since, which is why I'm starting to think I may have after all used the phone quite a lot that night, and the music player may have been left on (though muted) for the night, and perhaps this was the cause of it.
I would gladly set it to 2G mode to save some battery, but when I access the Internet I'd like it to be through 3G. Too bad there isn't a "3G mode only when using data connections" mode...
