Battery Life is an important aspect of an iOS device. With the launch of iOS 5, many users feel the battery performance of their iDevices has decreased significantly and there have also been claims that the battery life is below par than stated by Apple officially. However, the new Cydia tweak by Akhil Tolani may be a savior for those who use are fed up of their iDevices powering off when they want to use it the most. The tweak is called PowerSaver. Read on for more details.

This new tweaks allows users to carry out pre-defined actions when a particular percent level of the battery is triggered. The usual iOS system shows an on-screen alert when the battery goes down to 20% then 10%. Well, for me this isn't something that users didn't know already. What PowerSaver does is that allows certain power processes and system settings to switch off at a certain percentage thereby extending the functionality.

With PowerSaver, many actions are available, such as turning off Wi-Fi, rebooting or respringing the device, turning off the Bluetooth and much more. A great benefit is that it doesn't require additional battery to function, so it is pretty useful.

The tweak also supports up to fourteen unique alarms. Users can tigger any of them when the battery reaches a certain level. E.g. you can ask the tweak to turn off the Bluetooth when the battery level reaches 20%. If you can get a hold off when to turn off the right functions and how to work out the key levels, there is a high probability that you'll get a prolonged battery life.
