    I agree. Did 4,5 hour ride today and Karoo went from 100% to 50%. Getting more battery life is a must, even if sensors like HR and Power connected.

    Any suggestions to getting more batterylife?

    Hi, completed two rides with the new Karoo. Love it, but I am not sure about the 10-15 hours of battery life. First ride took almost 3 hrs and battery was down from 100% to 61%. Second ride, almost 1.5 hrs, battery down from 100% to 75%. Second ride no sensors attached and brightness level at lowest. Wonder how to get 10-15 hrs battery life...

    I've been riding all day for the past 12 days or so. Aside from Karoo rebooting itself and erasing all the data during the rides, when it works and is recording the ride just fine, the battery doesn't last 8 hours with the screen turned off. I'm not using it for navigation. Just recording the route as I go, and I have to use my power bank so that Karoo doesn't die.

    I've installed version 1.5.105.3 and after only 4 hours and 35 minutes Karoo went off.

    I had fully charged the battery, disabled the sensors, turned off the wi-fi and the brightness screen was at the minimum level.

    With this version Karoo is totally unreliable and unusable! It's useless add new features (such as ambient temperature) as the battery is so poor!
    I am very very disappointed with this product, I can't use it during my races.

    Mine lasted just over 5 hours today from fully charged.

    I had ANT and Bluetooth sensors on whilst doing a sportive. Disappointing. Is the Bluetooth particularly heavy use? My power meter can be used with ANT+ or Bluetooth so I could turn off the bluetooth if that is likely to save me some battery life....

    Yes, my problem exactly, going on a 30 hours ride this weekend, not many cycle units can record that long anyway but only having to charge once or twice is a lot better than 7 or 8 times!

    As of now I still think the Karoo is a great unit but I fear I will be parting with it soon, every longer race (5-10 hours) I did since I got it I switched back to my Wahoo Elemnt. 

    Having an awesome unit with amazing screen that allows you to travel into the unknown is pretty useless when it shuts down after 4 hours because of the batterylife.

    I'll wait till Hammerhead makes a unit 30% smaller with longer batterylife, they can cut down on some of the functionalities or let user add well knowing battery will suffer.
