38mm Apple Watch battery performance: A full day log

Followed by my previous post on 3 days experience with the Apple Watch, I want to do it again with detailed log on the interaction I had with the watch throughout a normal working day. I have the following settings that may differ from yours:

  • Normal brightness level
  • Muted
  • Activate on Wrist Rise turned on

In the 15-hour test, the battery life of my overnight-charged Apple Watch depleted for 81%, which is approximately 1% per 11 minutes. The battery life chart record and activity summary are as below for your reference. If you are interested in the full detailed usage log, here it is.

  • 25 Time checks
  • 11 Incoming messages
  • 1 Incoming phone call
  • 8 “Time to stand!”
  • 8 Complete stand / Activity progress notifications
  • 4 Glances and app usage
  • 27 minutes disconnected with iPhone

There are plenty of usage patterns that you may have, and there are a number of ways to preserve the battery life in case you overused at a certain period of time. One thing that you may consider is turning down the brightness level of the screen. It did help me to have run much better battery life a few days ago with approximately 1% drain per 16 minutes.

Notably speaking, the 27 minutes disconnection with iPhone drained 8% of the battery life. You may have seen this claim somewhere but this is true. One of the major reasons I can think of is that the Apple Watch has been continuously scanning for your iPhone in the background that lead to a severe battery drain. So bear in mind.

What is your experience on the battery life of your Apple Watch? Let me know in the comments.

  1. I get a feeling that the Watch idle isn’t far off what actual usage is. I had a day that I’d consider quiet and looked like your above usage and I ended on about 30% after 16 hours, then I’ve had days where I’ve at least doubled that usage, long message conversations with dictated replies and all sorts, yet I still ended on 30% after 16 hours.

      I share similar feeling. Idling seems not helping preserve battery life much. If you see my previous post, I used a lot more than today but still have over 30% at the end of the day.

    With modest usage (at least double what was tested here), I’m seeing about 15% battery remaining when I end my days – after about 15 hours of wear. On lighter days, I have upwards of 30% when I turn in for the night. I think the battery gets about the 18 advertised.
