Poor battery life. Fix? Replacement?

[mr_rockford]

Me and my wife bought Pine Time watches (the water proof ones) about half a year ago. We are both running InfiniTime 1.10. Her watch has more than a week of battery life while mine runs out after 4 hours. Disabling Bluetooth adds another hour.

What could be wrong with my watch? What can I do about it? Is it possible to send the watch back and get a replacement?

Hi,

are you using the InfiniTime 1.13 firmware? I've read, that the battery life was heavily improved from a few days days to a week.

And my actual question is: I don't have a really big advantage in battery life since 1.13. Does everyone with 1.13 have a much better battery life?
I don't know if just my battery degraded... It shouldn't, because my watch is about half a year old, and it's pretty much the same since arrival.
