If I have one complaint about my iPhone X, it’s that its battery life doesn’t quite match up to my old 7 Plus. If that’s been a hangup for you as well, ZeroLemon’s new case should just about double your battery life for just $25 with promo code 668T4RXO. Even at that low price, the case has Qi charging built in, so you’ll still be able to use your wireless charging pads.
