The batteries in my Jabra buds themselves last maybe around 5 hours? I've never really checked, but the case itself will charge them without any outside ac charge for another 10 hours? My numbers could be underestimating it, but at least the 5 hours.
I think that the case for my Jabra buds has an additional 15 hours of charging available, but the buds can't be charging in the case & your ears at the same time, unless you have a funny shaped head 🤣
But if you take a lunch break or can just slack off for half an hour or so, then the buds will get the chance to get recharged for another 5 hours.. don't know if that will work for you?
Yup, the case holds something like 3 full charges in it, so I'm guessing it should be around 15 hours 🤔
The case for the Jabra is pretty small too, so it easily fits in your pocket. Worst case scenario, people may think that you're "happy" to see them 🤣🤣🤣🤣 I'm not sure about the Galaxy buds, but Jabra are ip68 certified as well.
