13' 2015 mbp sleep/battery issue

[dragunica]

Hi, I am new to macOS. I recently bought my first MacBook 2015 (refurbished one) from a legit store. Everything is perfect except one issue. Whenever I put it to sleep, the battery is draining itself a lot. I have turned off bluetooth, wifi, turned off power nap and notifications when the MacBook is asleep. The battery health is good and the battery is new (sc on the bottom of the post) I have started up terminal and typed a command 'pmset -g log|grep -e " Sleep " -e " Wake " which gave me:

2018-11-18 02:04:39 +0100 Sleep Entering Sleep state due to 'Software Sleep pid=880':TCPKeepAlive=active Using Batt (Charge:83%) 42901 secs

2018-11-18 13:59:40 +0100 Wake Wake from Deep Idle [CDNVA] due to EC.LidOpen/Lid Open: Using BATT (Charge:60%)
between those two commands nothing showed up. What may be the cause/problem and how can I fix it?
I have also checked out the 'pmset -g' and it says:
Currently in use:

tcpkeepalive and ttyskeepawake are on. I'd turn them off and see if that made any difference first and foremost.

Both standby and autopoweroff are enabled, but their delay values are 3 hours or more (standbydelaylow 10800= 3 hours, autopoweroffdelay 28800 = 8 hours, standbydelayhigh 86400 = 24 hours)

A sure-fire way to mitigate battery drain would be to disable standby altogether and enable direct hibernation using sudo pmset -a hibernatemode 25 , which can be reset to default using sudo pmset -a hibernatemode 3

You could experiment with lowering values of standbydelaylow standbydelayhigh to something like 15 and 30 and see if that makes any difference. autopoweroff is akin to using hibernation, so lowering its delay to say 15 seconds in effect is the same as hibernating on the spot.
