I have had a similar experience to most everyone here with a slight variant. In July my Fitbit went from working faithfully needing to be charged every 5-6 days with heavy use and full features enabled and then one day after charging as usual I noticed the battery indicator was flashing to low after about 2 hours of use. I charged it back up to full and it did the same thing and shut off completely. When I tried to charge it after that, nothing. It was totally dead. I figured that was the life of these things. Seemed a little lacklustre for the money spent but oh well. My charge HR made it the same amount of time and only got decommissioned because the strap broke. But I digress.
So a couple weeks ago I popped into the Fitbit forums and started reading up on the issue. Reading about bad experience after bad experience. But also through reading many other threads remembered there was an issue a while back with the firmware and the battery draining fast in the past on other products so I decided to see if I could get my faithful Fitbit up and running again. To my surprise it turned and changed fully and worked as if it had never missed a beat. That was until this morning. After working for 2 weeks yesterday evening I needed to recharge after my 3rd complete 5 day cycle. I used it as normal last night and this morning. I had my usual routine and late morning as I was about to run some errands I looked down and noticed the watch was off. When I turned it on flashing red single bar of charge.
Here is where it gets weird. I synced and the app said full
charge, so I powered down the Fitbit, powered up and synced again and it still said full. I powered down the watch a second time and put it on th charger and it showed half full. Synced and it showed half full on the app. So I let it charge fully and delayed my errands so I didn’t lose my steps. I’m now finished with my errands 4 hours later and I am down to 1/4 charge left.
What gets me is that I never had a problem until it died suddenly a little over a month ago and then suddenly it works miraculously for over 2 weeks like new and then juat as suddenly starts failing again. The only thing that has changed in that time are a couple of updates to the Fitbit app. The most recent updates are 3 weeks ago and again last week. Which coencide with my blaze suddenly working again and now for some reason dying after a few hours of use. Something is draining the battery because a dead battery doesn’t come back to life temporarily and then suddenly die again.
