This tweak is a good prank that shows your battery percentage as a custom value on your iPhone or iPad. Set your battery to a significantly low percentage, like under 10% is sort of neat if anyone else sees your iPhone. Having your iPhone/iPad showing 2 or 3% battery remaining all the time is pretty cool. Just toggle FakePercent off in your SBSettings or jump into the extension and adjust the FakePercent shown.
This tweak is definitely not for everyone, but is a nice customization for pranking purposes. Itay is also responsible for the ClearSpotlight Cydia tweak. If you are looking for the best free Cydia tweaks for your iPad, you have come to the Cydia iPad authority.
