I know a couple of people who carry an extra battery in their wallet for their Nokia phones. They are really heavy users who tend to kill their phones earlier than the advertised battery life. Push email, while streaming music, while running GPS navigation, while running Sportstracker, while tweeting and recording live videos in between.
Yes it’s all possible with Nokia phones running on S60, but kills the battery sooner than you want to. If you’re a heavy Nokia user, let us know what you do to drain your phone batteries quicker than normal. How do you deal with it? Have a another battery tucked in your wallet?
