I've had my Bold for 6 months. Charge it every couple of nights. Several times the device has become very hot. Not while charging or usaing - just sitting there. The battery is drained and have to charge + reboot. It works fine once recharged.

Batter life on my Bold is pretty awful. If I'm using the web or doing lots of email, it will not last a day withou a charge. Pretty dismal in today's mobile world. What a shame for a great phone like this to be dogged with this label.

I wonder whether for Japan Blackberry have tried to increase battery life, my Bold barely lasts a day between charges (often less) and i dont even make that many calls with it. It's a good device but battery life is one of the main flaws with it.

I charge my work Blackberry 9000 Bold via a USB cable here in the UK and it's fine - doesn't even get slightly warm. The more annoying issue with the 9000 Bold is the utterly *dismal* battery life compared to the 8800 model I previously had. The 8800 could last between 7 and 10 days between charges - the 9000 lasts about 2.5 days (and that's with the screen off most of the time, 60% brightness when it's on, Wi-fi turned off, 2G used instead of 3G, not making/receiving calls or playing audio/video).

My LG wave gets warm when I charge it. It gets really warm when I tether while charging. I fear a fire when my phone falls into the couch cushions while tethering and charging.
