How long is the battery life of the H4 last? Jamie December 07, 2022 15:51 The battery should last around 14 hours. Related articles Can you adjust the screen brightness on my device? What happens if I forget to tag my shot on the H4? What is Manual Putt mode and how do I change from Automatic putting to Manual Putting? How can I contact support for more help? My device will not finish its sync/update (wheel keeps spinning/bar won't complete), what should I do? Comments 0 comments Please sign in to leave a comment.
