There are plenty of jokes out there about the battery indicator on iPhones. Some people complain about their iPhones dying randomly at 11%, while others see hours of use at the 1% mark.

But on the bright side, you can check any game's FPS with a simple tool.
Music streaming services make it difficult to transfer your favorite songs and artists from one service to another and for a valid reason: they don't want you to leave.
