Fitbit Software upgrade messed up devices battery life!

I’m am extremely disappointed with Fitbit. I have the inspire HR and purchased it July 2019. I would charge it once a week with no issues. Then I tried upgrading the software and first ther was non available for iPhone. And the 16 October 2021 I upgraded my software and instantly my battery needed charging. It was weird cause I charge on Sunday sometimes Saturday. The following day (18 October 2021) I had to charge is again but now three times and received an email about low battery problems from Fitbit.

On the 18th I was fed up and called customer service and they were not helpful. They told me to reset it to factory setting dose over the phone but now it’s lost time and doesn’t sync. If this is the same bull**** stunt to buy an upgraded version. Well Fitbit IT IS *******. My watch worked perfectly until the software upgrade and to turn around and say we have insufficient data to support my complaint to your customer server agent (Ali). Last night, I charged it before bed , the time was wrong, it had stopped updating time at 15:05 and this is now 20:00 but showing the time 16:00. I charged it so It can get a reading on my sleep, woke up this morning (19 October 2021) to a battery dead watch. Phone still refuses to sync
