Forerunner 945 average charging time?

Good evening friends! First post here.

I have read a lot of posts regarding the 945 battery life, but I haven't found one discussing the charging time. The instruction manual says it takes "two hours to fully charge the 945". However, mine usually charges to 100% MUCH quicker! Mine takes literally half! 1 hour to fully charge from 0%. I am using a computer USB port (not a wall charger).

I believe I have checked everywhere and no one discusses the issue.

Is this what you guys are experiencing as well? I was curious, as I had a night where almost 60% got drained, but then other night that went with only 10% (both measuring pulse ox).

I'm OK with charging the watch every 3 or 4 days, but I wanted to ensure that I am properly charging it.

Thanks! Best regards,

Rafa.

Mine's about an hour too, but typically I'll start charging it when its in its teens/20s.

About 45minutes as I usually charge from 20% to 100%. Then I will unplug. Don't need to wait for 2 hours.

I charge from 5% and I haven't timed it but no way 2 hours around an hour sounds right for mine. Also my friends same.

Thanks for the feedback! I am much more confident now. My 945 lasts for about 5 days monitoring my pulse ox during night, and I charge it after it drops below 10%. Thanks again.
