More specifically, there are two major problems here. First, the battery seems to be draining extremely quickly, and second, many report the screen going black. The latter is especially frustrating, as it seems the device continues to work and charge, but the display remains inactive.
Fitbit moderators insist that most of the users reporting these issues have actually not yet updated their Charge 5 to the new version 194.61 software, and are experiencing the battery drain and blacked-out screen while on version 188.58. However, many are saying that is not the case.
The worst part — and what truly makes this a disaster — is that once your Fitbit Charge 5 experiences these problems it essentially dies, without any way of getting revived. At least that’s what seems to be the case so far.
Unfortunately, if you want to prevent this from happening your best bet is to keep your Fitbit Charge 5 disconnected from your phone and from any type of internet connection, since the update happens automatically and users have no control over it.
