Hello,
Without changing anything in my watch usage, the battery that was lasting 2 to 3 days drops to a day, and to half a day, to a couple of hours.
I delete absolutly everything on it, factory reset : same battery drain.
As the watch is 2 years and a half, the support suggested to change it (but i had to pay 150 euros which is the price of the watch on amazon so ...)
So i ordered a battery from ali***ss, received a wrong one (received a lithium poly instead of lithium ion), but i tried it anyway.
Removing the battery on the watch is not easy and i destroyed the hr monitor doing it (the battery is glued to the hr monitor, so when you remove the battery, it breaks the hr).
But anyway, i charged it, and same, 10 minutes get you off 10%, with absolutly nothing running on the watch, except the bluetooth to my phone.
So i sent back the battery and bought a new one, lithium ion 3.8v this time.
received it, changed it, charge it, and the same, 10% lost per 10 minutes.
I am starting to think that this is not a battery problem, 3 batteries with the exact drain, it's either really really bad luck
or it's a software problem.
Are there some already known bug on this subject ? Or should i rollback to an older version ? (but which one ? and how to do it ?)
Even without the HR, i could use the watch for the outdoor activities.
