These are notes that I took while trying to find the optimal Apple Watch settings that maximize my battery life.

Day 1

  • Started day at full charge at 8:30 am.
  • Made a phone call from my watch to test it. About 90 seconds.
  • Received a phone call on my watch. Also 90 seconds.
  • Took a couple of pictures with the phone app.
  • Otherwise normal usage.
  • Battery above 10% when i went to bed at 3:00 am.

Day 2

Not tracking today’s usage because I woke up so late and it was a short day.

Day 3 - Monday

  • First weekday.
  • Put watch on at 8:20 a.m.
  • Added mirroring of Starbucks alerts.
  • Added mirroring of Slack alerts.
  • Added the Starbucks in my building as a favorite store. As a result, every time I activated my watch there was a Passbook alert waiting for me.
  • Battery went down to 10% by 10:43pm and died soon later, despite switching to reserve power.
  • Removed the Starbucks at work as a favorite store.
  • Turned off mirroring of Slack alerts.

Day 4

  • Put watch on at 8:20 a.m.
  • Went to Starbucks at train station. Also a favorite store. Decided not to use watch because wait was too long. Used phone instead.
  • Removed Starbucks alert mirroring off phone.

Update 1

  • Checked battery at 10:00 a.m.: 14%. WAT! Perhaps I knocked it off the charger last night.
  • Battery died completely at 2:10 p.m.
  • Will try again tomorrow and check power as soon as I wake up.

Day 5

  • Started the day at 0550 with a full charge.
  • It’s currently 1338 and I’m at 80%.
  • It’s looking more and more like yesterday was a user error.

Day 6

  • I took my charger in to work yesterday, just in case it wasn’t user error.
  • Because I’m a genius, I forgot my charger at work yesterday. Noticed it at 1800.
  • By then I was at 67%.
  • Put my watch on ‘Reserve power.’
  • Turned my watch back on at 0800 this morning. Glad to report it was at 63%.
