Your brand new $1,000 iPhone X comes with a charger in the box, but it’s not very good. According to Apple, the iPhone X (and the iPhone 8 and 8 Plus) actually support fast charging to the level of restoring up to 50 percent charge in 30 minutes. Unfortunately, it’ll be a bit pricey if you want to get those speeds, since Apple doesn’t include any of the things you’ll need in the box.

1. Use fast charge to recharge iPhone up to 50 percent battery in 30 minutes.

Fast charging gives you a quick and convenient way to recharge your iPhone X, iPhone 8, or iPhone 8 Plus. Your iPhone fast charges up to 50 percent in 30 minutes when you use an Apple USB-C to Lightning cable and one of these adapters:

Apple 29W, 61W, or 87W USB-C Power Adapter

A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

If you're not sure which Apple Power Adapter you have, check the wattage on the bottom of the adapter:

2. Turn On Airplane Mode

Turn on Airplane Mode on iPhone Control Center, this is the single best thing you can do to make sure your iPhone charges faster. Please noted that you wouldn't receive any call or message, and App notification when your opened Airplan Mode.

Mobile networks, WiFi and Bluetooth are all features which constantly drain your battery. Turning them off reduces a huge amount of strain on the phone and allows the battery to charge a lot faster.
