If you own an iPhone, probably you also do a lot of things on it, including checking mails, music, chatting, surfing etc etc. However, it's iPhone battery life that leaves us so scared that we think twice before checking our mail if we are not close to a charger.
Here are a few tips that will help you increase iPhone battery life. You might want to save a link to this page as I would be adding more tips in the future...
1. Avoid Location Based servicesGPS sucks a lot of battery. Avoid or don't allow applications to use Location Services as far as possible.
2. Keep that brightness level under control
Goto Settings>Brightness and adjust brightness to the minimum level required. Also, keep auto-brightness on.
3. Make use of Shortcut keysThere are three things you should do to not only save battery life but also make your work a little more easier with iPhone
- Arrange your Home Screen icons so that your most frequently used icons are on 1st home screen and closer to bottom (that is where your thumb/finger reaches fastest)
- Goto Settings>General>Home Button and set double click on home button to take you to favourites. Have all the frequently dialed numbers in your fav list. So whenever you need to call, double click on home screen and dial. (If this feature is on, you can actually have
some other icon instead of Phone on dock, as double click takes you there)
- When listening to music on headset, use the button on mic. (Yep, there is a button there.. just try pressing your mic). Single Click: Play/Pause (it even switches ON your iPod application). Double Click: Next Track. Triple Click: Previous Track
4. Turn off Wi-fi, Bluetooth, 3G when not in useThe only place I use Wi-fi is at home. So when I am leaving home, I disable Wi-fi from Settings and enable it when I am back. It saves a lot of battery. Similarly keep Bluetooth and 3G off when not in use.
5. Lock it when you are done with itWhen you are done using your iPhone, just press the power button on top once and screen is automatically locked. Common, but useful.
6. Fetch new data less frequentlyApplications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
7. Turn off push mail if you don't need itIf you have a push mail account such as Yahoo!, MobileMe or Microsoft Exchange, turn off push mail when you don’t need it. Go to Settings > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
