Polar OH1 and OH1+ get a firmware update

Both the older Polar OH1 and newer Polar OH1+ both have a firmware update.

Older Polar OH1 users should now find that they have Garmin’s ANT+ compatability…#cool.

Similarly you should be able to get ANT+ on your Polar H10 via the FLOW app or, soon, via the BEAT app.

Heya, is there any battery improvement either on watch or Polar OH1 when using ANT+?


The new firmware for OH1 firmware states

“ANT+ HR transmission
Polar SDK support
Battery life improvements for OH1
Improved OH1 interoperability with some mobile devices, including Samsung A3 and A5
Performance improvements and various bug fixes”

I had complained to Polar support about the battery drain on the OH1 when off issue. I was getting 11.5 hours continuous use, but if I tried to use it on several sessions over 2 weeks, it would struggle to do half that. Despite it being on many forums, seems like Polar had not had that much feedback to that effect. I hope the battery improvement is aimed at that.

I would be keen to hear feedback on what people’s experiences are of the new firmware and opinion on battery (mine is currently in for assessing if there is a battery issue so I can’t test).
