When you purchase an Apple Watch, it comes with a charger. But it's good to have an extra charger to keep in your bag. Especially when you are often traveling to different places. 

Apple engineered the Apple Watch to have an 18-hour battery life after an overnight charge. This is on the assumption that you will be wearing your smartwatch all day long. That estimate is actually based on checking the time throughout the day, receiving notifications, doing workouts, and using apps.  

How to Charge Your Apple Watch? 

The Apple Watch comes with a magnetic charging cable. You just plug it into a power outlet or a USB port. 

The battery life of the Apple Watch actually depends on how you use the wearable. Keep in mind that you don't have to charge your Apple Watch overnight. You see, it takes about 2.5 hours to charge the Apple Watch to 100 percent. It takes around 1.5 hours to reach an 80 percent charge. If you prefer it, you can even split the charging time between morning and evening.  

You can charge your Apple Watch in your car during a drive if you hadn't charged it or it was on low charge. Here's how: 

1. First, you should check to see if your car has a USB port. 

2. Then, connect the USB side of the charger cable into the USB port. 

3. Next, place your Apple Watch on the charger pad. Make sure that your Apple Watch is face-up on the charging pad. 

4. After that, check if the screen of your Apple Watch lights up. If the screen of your device displays a charging battery icon, then you'll know that your Apple Watch is being charged.
