Tricks for Long iPhone Battery Life
|

- Push e-mail. Turn off the “Push” feature, and set it to Manually instead (in Settings->Mail, Contacts, Calendars->Fetch New Data), then your iPhone checks for e-mail only when you actually open the e-mail app. Your battery goes a lot farther.
- GPS checks. In Settings ->General->Location Services, you’ll see a list of all the apps on your phone that are using your phone’s location feature to know where you are. (It’s a combination of GPS, cell-tower triangulation and, on some phones, Wi-Fi hotspot triangulation.) All of that checking uses battery power, too.
- Bluetooth have a similar battery usage as Wi-Fi, so there’s not much reason to leave it on if you are not using it
- Notifications. Similarly, in Settings -> Notifications, you see a list of apps that are allowed to display pop-up notifications (those blue text bubbles that look like text messages). To do that, they have to monitor what’s going on with your phone – and that takes juice. Turn off the ones you don’t really need.
- Background apps. This is important, new iphones, such as Iphone4 allows you to run multiple apps on the background, but this will drain your battery fast if you forget to close them. To do this, double click on the round button and it will show all the apps currently running, keep clicking in one of the apps and a red “X” will apear, then you can close all apps.
