One of us at the office – Blake of course – thought his iPhone’s battery had just lost its ability to charge. A full overnight charge would be gone in 5 to 6 hours. He had to keep the phone plugged in all the time, would often end up with a fully lost charge by early afternoon in traffic… Did he ruin the battery by having the phone plugged in the cigarette lighter all summer during a long road trip?

Why was the iPhone always warm in his pocket?

Well, turns out, after upgrading to the latest 4.2 iOS, using Push Email was a major battery drain! We had tried everything: turning off bluetooth, turning off Wifi, turning off location services… nothing seemed to do much except when we finally turned off Push Email Settings, especially since we had more than one email account – 6 in fact at the time. Now Blake has a full charge that remains in the upper 70 % all day despite many calls, facebook, twitter, email and shreddder (chess).

So turn off Push Email settings on your iPhone and thank us later. We on the other hand, would like to thank the Battery App from www.empowereddesignapps.com – it is simply the best app with a great number of integrated tips.
