Macbook air 2017 battery drained so much on Sleep Mode

I bought a new macbook air 2017 on March the 8th, 2020. When I set in on Sleep Mode (after quit all applications) , the battery drained about 10-12% after 6,7 hours on Sleep mode. I think this is extraordinary because I have another macbook air 2013 and after all day when I set it on sleep mode it just drains about 1 or 2%.

Either something is running excessively or there is a power related problem. For the former:


Using Activity Monitor


     Use Activity Monitor on your Mac

     Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity.

Using Activity Monitor Part 1- CPU and Memory

Using Activity Monitor Part 2- Energy, Disk, and Network


For the latter: Make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple. Also, see How to find your nearest Apple Authorized Service Provider (AASP) or Distributor (AAD).
