MacBook Air 2017 with Mac OS Mojave freezes after sleep, and sometimes it doesn't even wake up!

My first Mac OS on my MacBook was Sierra and everything was good, I didn't have problems with it. After updating to Mac OS mojave I have these: my MacBook after sleep freezes and works by 25%, furthermore I have problem with a battery drain. And unfortunately sometimes my Mac can't wake up.

So I have these 4 problems:

1)Mac freezes after sleep

2)Mac works worse after sleep, but if I'll restart my Mac it works OK or I can each time turn it off

3)Battery drain( I can fix it with terminal by updating sleep mode, but I want to hear: are there another ways to fix it)

4)Mac can't wake up
