iPhone’s battery drain issue has been complained about lots lately and the complains have really mounted since the recent release of iPhone 4S. Because of iPhone 4S’s battery issue, Apple released iOS 5.0.1. However, some users say battery drain problems are even worse after the iOS 5.0.1 update.
In the meantime, while Apple tries to solve this battery problem, there are some tweaks you can try to help you squeeze out more juice from your iPhone when you’re on a long trip. For one, you can disable some services in Settings and quit unused apps for longer battery life. This article’s about how to do that.

The push email and frequent data fetch features, operating say every 15 minutes, will drain a lot of battery power, and multiple e-mail accounts will make your battery drain even faster. Turn off the “Push” feature and set Fetch data to Manual mode (in Settings -> Mail, Contacts, Calendars -> Fetch New Data). Now your iPhone will only check e-mails when you open the Mail app, and your iPhone 4S’s battery life will last a lot longer.
Location services is constantly transmitting and receiving information, reducing battery life. Apps like Camera, Map and Compass will actively use location services to check where you are. To turn off Location Services, go to Settings -> Location Services. In the Location Services window, all apps that are using Location Services are listed. Disable those you don’t need to reduce battery consumption.
On your iOS device, launch Settings, tap Notifications. The apps that are allowed to display pop-up notifications will show up. These apps will have to monitor what’s going on with your iPhone to pop notifications and that takes juice. You can turn of them all or just the ones you don’t need.
Quitting those unused background apps can prolong your iPhone’s battery life too, and the result is quite significant when you have many apps, say 50, running in the background. To quit unused apps, double-tap the Home button to open the multitasking apps switcher. Put your finger on one of the app icons and hold it down until they all start jiggling. Then just tap the little X to quit the apps.
Use Airplane Mode
In Airplane Mode, WiFi and Bluetooth will be off by default, but you can still turn them on manually. To turn on Airplane Mode, go to Settings and set the Airplane Mode to on. WiFi and Bluetooth networking pull a lot of juice from your battery. Only turn them on when you need it to improve battery life.
