Charge 5 battery life

[JW120]

I called customer service yesterday, not for the first time, but the 4th.  In June of 2021 my then fitbit tracker, which I had for a couple of years,  broke when I tried to change the band.  No biggie, I just purchased a new one (upgraded to a Charge 4) at Target.  Five months later, it just quit working.  Called customer service, ran through all the scenarios to fix, but they determined it was defective and sent me a new one.  Fast forward to September of 2022.  There was an update that was required to do.  Immediately my fitbit stopped working, the battery would charge, but would be dead in 60 to 90 minutes.   So again....called customer service and because my fitbit was more than a year old, they would not replace, I could purchase one at 30% off from them.  So I did....Seven weeks later--it died.  No response.  So again, was replaced.  That was last November. They sent out a completely new fitbit and all was good--until this weekend.  I put my charge 5 on the charger when i went to bed, in the morning i put it on, but within 2 hours it was dead.  I cleaned the contacts thinking maybe it did not charge fully.  Then rebooted it for good measure.  The charge lasted only about 75 to 90 minutes.  So I called customer service.   They want more info as to how long the battery charge lasts.  This is the 2nd fitbit in less than a year, 4 fitbits in just under 2 years....Something is not right here!

I agree, something isn't right.  I'm thinking something might be wrong with the charging cable, is there a way that you can get a hold of another Charge 5 charging cable and run a test for me?  Charge the device fully on the new cable and see how long it lasts.  If it lasts more than a few hours, then we know that it was the charging cable.  If not, then there might be something wrong with the charging socket.

I too have had all 3 of my Charge 5s at one time or another runn 100% charge to 0% in 90 minutes or less.  Did a restart and a frmware update, and sometimes after the 3rd attwmpt of both, normal battery drain reoccurs.  Something is very wrong.

I had 2 different cables that I tried.   Plus, this isn't "my first rodeo" if you get my meaning.  This is the 4th time to replace in under 2 years, all because it would not keep charged! Sent from my Verizon, Samsung Galaxy tablet

Ok great, then that leaves us 2 options: something either being wrong with the charging socket (doubtful, but worth a shot) or something malfunctioning with the battery itself (more likely).  I know you said you contacted Support before (great idea, by the way), but when you contacted them, did you have them run a Battery Test?

It's not the charging cable, it's the software update they pushed through last week. Suddenly lots of Charge 5 wearers had black screen last Wednesday. At first I thought it was because I wore it at the beach, which makes no sense because it is water resistant to 50 m and has a swim track function. When I got back home a few days later, I did a hard reset of it, the screen came on and it said it was 100 percent charged. Within a few hours it was down to 4 percent charge. I thought maybe I was mistaken about the charge and recharged it. Again it was 100 percent and dropped down to less than 50 percent in an hour. I did the online chat with customer support and they told me to do all sorts of things that made no sense, like synching it exactly nine times  between 100 percent and 0 charge so they could "see" the battery usage. I told them they could already "see" the battery usage and that it made no sense. Then I simply said, "I've done all the things you suggested." They asked where I bought it (Fitbit site), and determined it was still under warranty so they will send me a new one. Hopefully this one works. In the meantime, I'll use my old Charge 4.
