Please note that new batteries in Swimmo watches are not fully charged before packing due to shipping restrictions. That’s why we advise charging your watch to 100% capacity before the first use.
If the battery seems to be draining too fast (it should be enough for up to 5 hours of continuous workout or 5 days of idling), it might be due to one of the sensors or other components not initiating properly during the first start-up. In that case, a hard reset should fix the problem.
If this did not help, please email us with details of the problem you are experiencing and the steps you have already taken to try and fix it.
