So how to improve iPhone 4 battery life? Here we are going to share some tips that will help you to reduce iPhone battery drain.

Tips to Improve iPhone 4 battery life:

In iOS 4 Apple has added some of the new amazing features and multitasking is one of the best among them, which allows users to use Pandora, Skype, GPS navigation apps. But on other hand it will consume lots of battery life.

For now it will be unfair to say either multitasking is the cause for battery life or poorly-programmed third-party apps.

But luckily here are few iPhone 4 battery life tips to increase it.

1). Turn off push notifications – Push notifications consumes lots of iPhone 4 battery, turn it off to save battery.

2). Turn off push e-mail – Turning off push e-mail will also help you save lots of battery life. If not necessary turn it off.

3). Turn off radios those are not in use – Turn off Wi-Fi, Bluetooth, and GPS while you are not using iPhone.

4). Stop background tasks – While iPhone 4 is multitasking, you should stop encounter apps that eat up battery by polling the Internet in the background.

5). Set display brightness to auto adjust – Set display brightness to auto adjust to save battery life.

6). Turn of Vibration – You should turn of vibration while playing game in iPhone 4.

7). Use battery case – Use iPhone 4 batter y case.

8). Sync iPhone periodically – Make practice of Sync iPhone periodically, which will increase your iPhone 4’s battery life.

9) Turn off apps that use location services. Such location services apps run in background and can quickly drain the battery.  Go to settings > General > Location Services and select the apps for which you want to disable this feature.

10) Check out Internet tethering on your iPhone that seems to be persistently attempting to establish a connection. Go to Settings > Network, select “Internet Tethering”, and tap on “Cancel” to stop it. Turn WiFi off and back on again so you can stop the tethering connection attempts.

On both phones we set the screens to full brightness and rented a standard definition video (Shaft's Big Score) from the iTunes Store's 99-cent library, which took about 45 minutes for the phones to download over the office Wi-Fi network. We then played the 1 hour and 43 minute movie in widescreen mode.

Next, I downloaded the free Pandora application from the App Store over 3G and then surfed the Web while Pandora streamed music in the background. I did this for 30 minutes on the 3GS and then made a 14-minute phone call before the battery died. Total battery test time for the 3GS was 3 hours and 14 minutes.
                           
On the iPhone 4, I was able to browse the Web with streamed musical accompaniment for 50 minutes, make a 30 minute phone call and watch another 44 minutes of Shaft's Big Score before the new phone called it quits-4 hour and 32 minutes after testing began. And while the iPhone 4's 40 percent longer battery life was truly impressive, I worried that the year-old 3GS's battery had significantly less capacity than when purchased.

As I was set to post the story, Macworld Assistant Editor Lynn La mentioned to me that she'd purchased a new iPhone 3GS just two weeks ago. She graciously allowed me to take her phone for the day and I ran the tests again.
