For what it's worth to people to know, it would seem that the commonly seen battery fault isn't the sole issue of the firmware. I have 2 vivoactive3 devices, one without issues and one with a battery fault.
Now, the device without issues has some scratching to the display that the faulty one didn't, so I thought, seeing as they are both out of warranty anyway, I might as well do some experimenting. I disassembled both devices and found 2 things, firstly.the main PCB in the device is what holds the pairing/installed widgets information, this moved between watches when I changed them over, and secondly, the screen/display and it's potted PCB is where the issue lays with the battery!
No matter what combination of parts I reassembled the watchs with, the unit that got the "good" display, ALWAYS displayed the battery issue, (24hrs tops)and my old natty display continued to get a good 4/5 days battery life.
Both devices got the same firmware installed to them, and both were tried with all swappable hardware to determine this.
My next step is to ask someone who might have a bit more knowledge on the hardware, is there any information that would be useful that is accessible either via PC connection or via the built in diagnostics, what would help determine what the hardware differences are between the 2 displays? I ask, as I'm sure the combination of hardware AND firmware is to blame! It might help Garmin find a solution perhaps?
