David Pogue from the New York Times recently got some tips on improving iPhone battery life from an Apple Store Genius. We've discussed how to get the most out of your iPhone's battery on TUAW before, but it's worth revisiting since both the iPhone itself and the software it runs have changed so much since the last time we discussed it.
Three out of Pogue's four suggestions for improving battery life come straight from Apple's official battery life tips. First, he suggests turning off push email and setting email to fetch manually. Depending on how many email accounts you have, this could dramatically improve your battery life, but it also means you won't receive new messages until or unless you open the Mail app.
Pogue's second suggestion was to turn off Location Services for apps that don't necessarily need to have an active GPS connection. This tip makes sense if you're making heavy use of a camera app or a Twitter client with GPS tagging, but since Location Services generally doesn't run in these apps when they're running in the background, it's only going to make a positive impact on your battery life if you're spending a lot of time using these apps.
