I have been using the Samsung 8300 for over a week now and I'm not impressed with its battery life.
It clearly states that it uses 4hrs talk time and 15 days stand by. In reality I have had to charge my phone three times already. I don't use it to play mp3s, only to send a few txt and voice calls totalling no more than 20mins.
I do realise that the Samsung is a touch screen and it must use a lot of power.... but the information provided by my local telecom store and the Samsung website clearly stated an expected longer battery life.
Other than the battery life it is a rather sexy phone.
Anyone else experiencing this problem?
