As I continued observing, my battery during sleep/hibernate mode (default)... looks like the battery draining issue solved on my mbpro 13 retina. only consumed 3-5% max on overnight.
macOS High Sierra v10.13.6 updated via appstore to macOS Mojave v10.14.1, I did:
- reduce motion in accessibility/Display
- stop auto update on appstore
- turn off location services
- untick auto adjust brightness
and this works on my side...
But, normal usage battery draining issue still remains the same. from 100% to 5% in 4hrs max... mostly safari and messages apps using significant energy.
Informing Apple via tweeter and they always give me this link: https://support.apple.com/en-us/HT204054?cid=tw_sr
Don't even bother telling "Apple is working in it, blah blah blah... nothing from them"
