I am using iPhone 4 from past few months now and the only thing I don’t like about the device is its battery time. With normal day to day work, emails, phone calls, social networking etc, the battery normally lasts for almost 1 day If its fully charged. If you are one of those who are looking for a way to improve the battery life of iPhone 4, follow some simple steps below. These steps worked for me and my battery life improved significantly.

1. Reduce Brightness:

Reducing brightness can improve the battery life of iPhone 4. The display of iPhone 4 is excellent (Retina Display) which used a lot power if the brightness is set to high. Go to Settings > Brightness and set it to something below 65-70%.

2. Close Apps Running in Backround

Always make sure all the apps are closed and there are no multitasking apps running. To do that, press the home button twice and you will see the apps running in the background. Tap on any icon for 2-3 seconds until they start shaking with a “minus” sign on them and close all of them.

3. Disable WiFi

Make sure Wifi is disabled and not running. Otherwise, it will keep on searching for available networks wherever you go and will require power.

4. Charge Properly

This is really really important. Always charge your iPhone 4 sensibly. What I mean here is that don’t put your phone on charge overnight. Remove it as soon as its fully charged and after that use it till the end before charging it again. Many of us including me leave the phone for charging overnight and then unplug when we wake up in the morning which is not at all good for the battery. This may reduce the life of the battery in long term.

5. Adjust Data Fetch Settings

Always make sure that data fetch settings is set to manual rather than automatic. For those who get important mails and need to sync from time to time can set the fetch timing to hourly or 30 minutes.

6. Turn off 3G

Last but not the least, disable 3G. Disabling 3G can have a big impact on your battery life. You can disable 3G by going to Settings > General > Network and then disable 3G.

These steps helped me and I hope they will help you as well. If you know any other trick to improve battery life, please share.
