Battery for E4 42mm lasts only for 12 hours

[JasonGraham]

Hi,

I just bought new E4 42mm and I love it. However, the battery lasts only for 12 hours and maximum of 14 hours; is this normal?. I tried to turnoff the always screen on option however that did not help.

I did reset again and the battery did not improve.

Give it at least 3 to 4 charging cycles.
Mine lasts a full day always.

I had a similar battery issue until I reset everything and turned off the always-on display. Also noticed that using tilt-to-wake instead of tap really helped. As for smaller electronics, when I swapped a button cell recently, I was looking for an lr1130 battery equivalent and found out there are a bunch of options out there—all about finding the right one for the device.
