Hey,
I had recently purchased a Neo 2 PrimeBook last month to experiment how it looks like working on an Android Operating System after using Windows for all this time. Initially, the laptop worked fine to the extent of my needs. However, after two weeks of use, the battery life seems to shrink. During the first week and half it used to be active for 7-8 hours but after two weeks the battery percentage drops in less time. For example, if the device is charged to 100 at 2 PM the battery drains to 75 in mere 2 hours even if there are no background applications running.
