Tips to lengthen your iPhone battery life.
One of my friends was complaining to me about the fact he needs to charge his iPhone nightly. Apparently his old "WinMo" device would last at least two days.
Like I told him, the first thing to keep in mind is that he uses his iPhone much more than his old HTC - you probably do too. If you use the device more, the battery is going to be consumed much quicker. Also, your old phone was probably an Edge device - Edge consumes much less battery power.
That being said, here are some tips to get at least two days off of a charge:
- If you have an unlimited data plan, turn off WiFi. Doing this by itself doubles the battery life on my iPhone. It is that simple.
- Unless you need it, turn off Push email. Push will keep a persistent connection open which means you are pretty much always moving some data around. That definitely hurts battery life.
- If you are looking for that last little drop, force the phone into "Edge Only" mode by disabling 3G. This tip is useless though if you have WiFi enabled because WiFi consumes so much battery power that you won’t notice the benefits.
Personally, I get about two days with WiFi off and that is good enough for me (I will turn it on but only when I need it and immediately turn it off when I am done). I leave Push and 3G on.
