I have closed apps and checked any possible drainers on the watch but it still goes dead in less than 6hrs??

Hi @mystique28 , Try changing the battery first and check the watch’s performance. 2-3 years is a reasonable lifespan for a small rechargeable battery. Here’s a link to the ifixit Asus ZenWatch 3 Teardown guide. This should be of some help to gain access to the battery so that is can be replaced. The battery model number is C11N1609. Here’s a link to just one supplier. It is shown only to give you an idea of the cost of the part. There are other suppliers online that may suit you better. Just search online using the model number of the battery only in the search box of your browser to get results for suppliers of the part.

You should check the battery. This can happen because several reasons. it s lifetime might be about to end. Make sure to block unnecessary notification ,adjust the brightness level and turn off wifi syncing. These are usually save the battery life.
