So you’re having bad battery life on your brand new Sidekick 3. Before you open your mouth and start complaining, give this a try:
We tried this and noticed a significant increase in battery life right away. We got to 12+ hours with heavy internet usage all day long. One thing we did notice but aren’t sure of the validity: When indoors and with a bad signal, it seems the battery drains more quickly as it searches for a tower.
On a similar note, yes you will see the battery having weird percentages sometimes after charging. Ours likes to show more than 400%. Either reboot the device (1+@+0 at the same time) or plug/unplug a charger and if should go back to normal.
Finally, hang tight, since the battery is now removable, there are companies out there working on extended life batteries that will keep you going for much longer. Be prepared to drop a few $$s for them though.
