[From Tim Till] Sammy,
Thanks for posting all these great submissions! Many people who just
got their new smart phones notice how fast they use up their
batteries. First, turn off 3G/EVDO/network whenever you are not using
it. Sure, you won't get push emails, but do you really want email
bothering you all day long?! Second, turn off backlighting to
keyboard and turn down the backlighting to the screen. Third, there's
an app called
Power Hero for Palm and there might be similar ones for
Windows Mobile. I set it to turn off data network after 5 minutes, IR
receiver off when I don't use it, and I schedule it (every night) to
shut off everything except the phone.
