When your iPhone’s battery is depleted, it can’t charge fast enough. Being stuck without your phone often means being stranded without social contact, your map, your music library and your video game collection among other things.
The iPhone doesn’t have quick charging technology built-in like some Androids do, but there are a few things you can do to make your iPhone charge slightly faster. The less your iPhone is doing, the faster it’s battery will recharge. This is why many believe switching your phone into Airplane Mode helps it charge more quickly, since this cuts off the phone’s ability to connect to the Internet and fetch information. If you still want to receive texts and calls while charging, there are some other settings you can change to make your iPhone charge faster. Turning off Wi-Fi, lowering the screen brightness, and disabling app notifications can help.
Apple also says removing your iPhone’s case may help it preserve battery life, especially if it’s overheating. If you have an iPad charger readily available, try charging using it to charge your iPhone to speed up battery replenishment.
