Battery voltage 3.097 is shown as 3.97 on the device, during the waiting for data screen.

Unable to force other values to see if it's only for this specific value, but I assume all X.0XX values behave similarly.

Thank you for this observation, can you confirm this is on an M3 tag?

That is correct. I’ll just supply all the information I have on the specific tag (even though some of it is kinda redundant).
It is the only tag I have that goes beyond 3 volts, so I don’t think it’s device specific, but probably just because it's the most likely to show the .0xx behavior.

(Either that or it's because it's the first tag that has 3 decimals on voltage (I don't know), and the 'AP Found - Waiting for data' screen doesn't account for that?)

battery voltage fix.zip
Will not make a new binary at this time for the repo, since this is a small issue. Fix will be included in future release
