I bought the Hammerhead Karoo 3 last week. I unpacked it, mounted it on my Grizl, updated the software, and adjusted a few settings.

Today I went on a short ride of about one hour. During the ride, I noticed that the battery was dropping by at least 1% every 5 minutes. That would mean a total battery life of only around 8 to at most 9 hours. That is significantly less than the roughly 15 hours that are advertised.

I had my phone paired, Wi-Fi disabled, and no sensors connected. During the ride I used 3 data pages:

1. Map and speed
2. Six data fields with speed, elevation, average speed, distance, and distance to destination
3. Weather app and Climber

For most of the ride, I was mainly using the first data page. Display at roughly 30 %.

Since I can still return the Karoo, I’m wondering whether this is simply normal behavior or if I may have received a unit with a bad battery.
