Charge 6 battery life after update

[ASkijoke]

I did an update to my Charge 6 a few weeks ago (app says it's version 20001.220.31) and ever since doing that my battery life is all over the place. I will see that it is low and go to charge it and it will go from 6% to 75% in a matter of minutes. I typically will leave it on the charger for and hour or two though to make sure it's truly fully charge. On the other side of things though the battery life will say that it's at 21% and then all of a sudden drop to 8%. 

I've had this watch for about a year and a half and never had any issues with the battery life until I did that update, anyone else having this issue or know a way to fix it or reset my watch to an older version?

Hello @ASkijoke 

When my Charge 5 started having rapid battery loss, I restarted and recharged my device multiple times over several days. As soon as I saw a rapid drop in battery, I restarted my Charge 5 and put it on the charger until it was back to 100%, often doing this multiple times in a day. Eventually, this process got my device "unstuck" and the battery went back to lasting 6-7 days. Although there's no guarantee that this will work for your Charge 6, it might be worth a try.
