  • Enter/correct coordinates in Russian: impossible, every time you enter coordinate you get cardinal letters S/W instead of N/E.
    Still user magnetic variation input does not save value (Stays 0 E or 0 W, no matter what you enter). Menu Language is Russian.

    Too early to say.

    I installed it yesterday evening. Got the 96% battery meter stick issue, rebooted and left to charge to 100% and put it on. Went to bed. 10 hours later its now on 99% and got my sleep tracking data. Off for a run later.

    EDIT: 2 hours later just about to head out for a run and it is still at 99%. Rebooted watch and now reports 95%. Battery meter problems STILL ongoing :(

    What happens if you reboot again? Right after the reboot?

    Doing a boot up of the device isn't going to be a zero cost operation - especially as it does a significant amount of work loading up maps etc.

    My guess is that the hardware that tracks battery performance re-calibrates when the watch is being more demanding during boot up, and has slightly off calibration.

    PS. I don't reboot my watch ever - except when doing firmware updates, so I've no data to go on.

    I am not wearing my 5+ today as its a rest day and I have a hangover :) will check tomorrow when I have a 15k run planned.
  • Battery life seems fine to me on this Beta. I did a full charge friday afternoon. Did a sprint Triathlon on Saturday morning.. so about 1:20 GPS time with transitions and pre-race GPS sync. Normal wear the rest of the weekend and I Have 65% battery left this morning.
  • Have anyone noticed how few comments the latest beta threads have received?

    It seems we are getting close to a version, which works for everyone.
  • Find phone function runs at least once again after phone was found and confirmed. Previous betas had the same issue.
  • For me at least with 6:64 and 2.31 Sensor Hub Beta I have battery drain worse than 6:62 - also OW Swimming GPS still poor - despite good GPS Signal shows my start point 50 M from my true start
  • I get lap audio prompts on runs, but not on bike rides. Anyone else have this issue?
