When the battery percentage on your iPhone or iPod touch hits 20% or 10%, you will get an alert right in the middle of your screen telling you that you have low battery. On an iPad, on the other hand, you get an alert at 10% and 5% instead.
A new free jailbreak tweak dubbed iPad Battery by iOS developer Rabih M is now available in Cydia that will make your iPhone or iPod touch to pop up battery alerts at 10% and 5% just like on the iPad, as shown in the screenshot above.
There are no options to configure. The tweak only works on an iPhone or iPod touch and doesn’t work on an iPad; it requires iOS 6 or later to be installed.
