Why wait so long to recharge your watch?
Silly.
I wrote this thread 1 hour after my run then I went to work. I will charge it when I back home. I also want to know if it can last some more hours when low battery warning alert. Sorry my English is not good.
My question is: why did you not recharge your watch yesterday?
HTH
during activity is battery under load, because GPS, logging and other functions requiring energy is running. Batteries under load losing voltage. After stopping activity drop consumption and battery voltage increased. this is probably reason why then indicator shoved 1 bar.
