Turning Off the Wrist Heart Rate Monitor. The default setting for the ForerunnerĀ® 235 is Auto. The device uses wrist-based heart rate automatically unless there is an accessory heart rate monitor connected to the device. Select Menu > Settings > Heart Rate Monitor > Off.
On one occasion on a high intensity short ride, the 235 had my heart rate at about 120 bpm compared to 160 bpm from the chest strap. It did get more accurate after a while, but it shows that sometimes the heart rate accuracy from the 235 can be quite a bit over or under the correct values. Personally, I wouldn't worry about it.

At first I thought I must have been accidentally turning on running mode but have since realised that the wrist based heart rate monitor is permanently on which I believe is the cause of the poor battery. I have restored all settings, done a soft reset and done a hard reset. All failed to solve the issue. The watch is; Software Version: 7.50

Mine tends to slip down towards my wrist when I'm especially sweaty, which of course causes trouble with the heart rate reading. Tighter doesn't help, as I'm trying to wear it above the narrowest part of my forearm. I've considered putting a thumbtack in my arm, but instead just push it back up and ignore the oddities in the recording.-- Pete
I chose the 230, upgrading from my FR25, as it did not have wrist based heat rate monitoring. Heart rate monitoring is important to me, but the wrist based units just do not have the accuracy I want. If you want to use the 230 to monitor your heart rate, you'll need and ANT+ rated heart monitor chest strap or similar device.

This (along with basic information like your age and sex) is what GPS watches like the Garmin Forerunner 230, 235, and 630 do, by having you run for at least 10 minutes while simultaneously
