I just got my first Apple Watch today! But I’m noticing that the battery is draining really quickly. Is this normal? This is my first time with an Apple Watch, so I’m not sure if it’s supposed to be like this. Any suggestions on what I should do?
It might be that there are some background processes running for the first time. My watch lasts about two days without Always-On Display (AW9) and with 1-1.5 hours of workout.

What’s AOD and BG? Also, how do I check the sleep score?

Wait, what sleep app? And how did you get that screen? I didn’t get help setting up the watch in-store because I had to update my phone first.

There’s a teal bed symbol app on the watch itself. It connects to the Health app on iOS, and all your data will show up there. You should set up the sleep app and add a sleep time. Every morning, you’ll get a sleep score.

Ah, I didn’t delete it when setting up my watch. Looks like I need to redownload it.

Thank you so much for all the help! You’re amazing.
First, fully charge your watch. This gives it a better chance to complete the background setup. It’ll probably take a few days to stabilize, and battery drain can be above average at first.

Okay, that makes sense!

Setting up a device uses a lot of power. Exploring features, testing widgets, and syncing media can drain the battery. Once you’ve finished setting everything up, you’ll notice a battery improvement.
First, charge the watch fully and let it finish updating and processing anything it needs to do for new apps or software updates. This takes a lot of power. After that, it’ll back up to your phone. If you let it charge and discharge a bit, it’ll stop unnecessary background processes that could be draining the battery. It won’t keep doing that when the battery is low to avoid bricking the watch. Let it sit overnight to clear most of that out. The first few days, it’ll use more battery to set up things like health tracking and Siri. After that, your battery life should improve. Once you get into a rhythm of charging and using the watch, the battery life will get better. After a week, you should notice about 24+ hours of regular use unless you’re a heavy user, in which case, you might still get 18 hours. Updates can sometimes drain the battery a bit on the first day or two, but in the long run, they can improve battery life.
