From the day of release of the Apple iPhone 4S, battery issues are surfacing and Apple has failed to get the bugs fixed, which are a major cause in iOS 5 for poor battery life.
Other Apple devices which have been upgraded to iOS 5 also perform poor in battery backup.
Recently, Apple launched an update to iOS 5, version 5.0.1, but it too failed to get the problem solved.
The reason behind the poor battery life can be due to heavy apps and services like Siri or iCloud service.
Here are a few tips that will help you to improve your battery life on iOS 5:
- Disable iCloud: According to a massive amount of forum postings over at apple.com, iCloud is the biggest battery drainer app. You can disable iCloud from Settings->General->iCloud.
- Disable Connectivity You Don’t Use: Connectivity, in form of Bluetooth, Wi-Fi or 3G, consumes the most battery for any phone. You can disable Wi-Fi and Bluetooth when they are not required. For improving the battery life significantly, 3G should also be disabled.
- Disable Location Based Services: Disabling Location based services will save a good amount of juice in your battery, but it may affect overall functionality of the device. It is better to disable those services/apps that you do not use. Go to Settings->Location Services and disable the unworthy services.
- Lower Screen Brightness: More screen brightness, more battery consumption. 40% screen brightness is enough in most conditions. Automatic brightness is also an alternative option.
By applying the above listed steps, you will notice a good improvement in your iOS 5 device. However, there are also some other minor tweaks, but these will serve you well. Third party apps are also available on iTunes to get the mission “Battery Save” accomplished
