First charge from 100% results..

2 hours 57 min usage
9 hours 46 mins standby
Worked out for an hour on LTE streaming music through Bluetooth device.

Battery was @ 19%. Unacceptable.

2nd day I charged to 100% over 24 hours ago without using LTE this time and the results were much different.

After the first 16hrs and 33 min’s standby with 2 hours and 33 min’s usage my battery life was @ 61%.

Then after a little over and hour workout using the workout app and streaming music through Bluetooth the battery went to 52%. Not bad.
Then just now..after 1 full day and 1 hour in standby (25 hrs) and 5 hrs and 51 min’s usage my battery is @ 25%. That is excellent and more like how my Series 3 performed.

I will test again after charging to 100% and run the workout app and stream music over LTE using Bluetooth headphones and see if it was indeed the LTE that drained my battery so badly the other day or if the battery is just going through a “break in” period. I’m very happy with the battery results without using LTE so if my results show LTE was the culprit I guess I will just need to refrain from using LTE and cancel service. It’s not a necessity anyway but I do like the idea of not always having to be tethered to my iPhone at all times and still being connected.

Thank you! please do let me know as i plan to run my AW solely from LTE without the phone present, if the battery is drained before the end of the day i might have to pass on a purchase of the AW.

thanks.

apple watch has had built in GPS for sometime, even though LTE is turned off. so when LTE is not needed (such as on a trail run or hiking) certainly makes the series 4 with good battery life an ideal watch for me.

Follow up with results from today..

I took my Apple Watch Series 4 off charger this morning @100% at around 8am..
—24min’s usage
—2 hours 5 mins standby
Battery still @100%

Put my watch on LTE and worked out for an hour using the workout app and streaming music through my Beats Bluetooth headphones. (Different from Bluetooth device I used for 1st battery test which seemed to drain battery quicker)
Battery dropped to 85%.

Just now..
—3 hrs 14 mins usage
—14 hrs 51 mins standby
Battery is @59%

Very impressed! It seems the Bluetooth device I was streaming off of on the first test which was some cheap Bluetooth adapter plugged into the back of a stereo system was not very efficient and drained the battery ridiculously fast. After using Beats headphones, the battery only drained 15% on LTE while streaming music with the workout app running. I’m a lot more confident in using LTE now and I think I’ll keep it activated. :)
