Maximize Your Apple Watch Battery Life: Tested & Proven Strategies for 1.5-2x Longer Performance

How long can you make your Apple Watch’s battery last? Between the 5 recommended tips by Apple, I’ve narrowed it down to two which are screen settings and Low Power Mode. Also, there are two recommendations that Apple makes that don’t actually work, especially the one that costs extra money!

Now Low Power Mode is going to net you the most battery savings at the cost of the functionality of your Apple Watch. With Low Power Mode, I was able to stretch my battery life from 2 days to 4 days but again, I didn’t really use my Apple Watch (it was basically dead weight).

My recommended Apple Battery Life saving strategy? Turning off Wrist Raise Off and the Always on Screen off. My Apple Watch Ultra would get a 50% boost in battery life and my Series 8 would get a 20% boost in battery life. If you’re using an older model like the Series 3, the savings is considerable!

For Apple’s first recommendation of turning on Power Saving Mode (which doesn’t exist, it’s Low Power Mode in the workout settings), I observed a savings of 2% over 2 hours which isn’t significant considering you couldn’t extrapolate the savings into a 24 hour period since most of us won’t workout for 24 hours straight.

“Use an external Bluetooth HR monitor” which is Apple’s second recommendation will actually cost you more battery power which is the exact opposite of what Apple claims will happen.

Bluetooth is a funny thing. Toggling the Bluetooth in Control Center resulted in decent battery savings though technically it doesn’t do anything to the Bluetooth connection between the Apple Watch and iPhone. With Bluetooth completely off (disabled in the settings), the Apple Watch’s generally lasted the same as regular usage.


A few things about how I got the observations for this video:

-Each observation was recorded manually by recording the start battery power and end battery power after each interval
-Each test value was based on the averages of at least 10 observations (so to establish a baseline for the AWU took about two weeks)
-The observations were taken during the waking hours which is why I did 12 hour and 8 hour intervals
-I did do observations during the night but didn’t include those in the averages
-I used the Apple Watch’s during the tests as “normally” as possible (i.e. workout tracking)
-All Apple Watches used in the testing were paired to iPhone 14’s except for the Series 3)
-All Apple Watches were running watchOS 9.3 (except for the Series 3 which was running watchOS 4)
-I’m right handed and I kept the Series 8 on my right hand for testing so those observations will most likely be higher in terms of battery consumption
-The AWU was kept on my left hand throughout this entire testing process

Collecting all this data was tough. Had some syncing issues at the beginning where I lost about a week or so of data. Trying to keep track of all the different things I was measuring was also annoying as I would have different timers going all the time and sometimes one would go off and I had no idea what it was for.
