Battery Life

Former Member over 4 years ago

I have had my Forerunner 645M for a while and the battery has always lasted a few days for me up until the past week, I have to charge it every day with just an hour(+/-) run each day. I am thinking I might have to do a factory reset to make it better if there is something using a lot of my battery without me knowing but I want to exhaust all options before i come to that point.

Any tips on how to get better battery life?

I had this problem, too. After I charge my watch, I always either restart the watch (Power Off, and then back on in 10-20 seconds) or do a reset where you hold the light button down until the entire watch stops, and then restart. I don't know if that's a "soft reset" or what, but it seems to slow down the discharge of the battery, at least for me.

Which GPS option have you chosen? I've read some use more battery than others.
