Sleep draining MacBook air battery life

Hi,

I recently noticed significant (20-50%) of battery life draining while my MacBook air 2013 is asleep. I found an article at Excessive battery drain while sleeping after 10.13.4 update discussing the same problem and that the Terminal code "sudo pmset -b tcpkeepalive 0" will help with this. However the author of this indicates this actually did not help, and that this deactivates Find My Mac while sleeping. I would like to undo this action, can anyone provide some insight as to how to go about doing that so that Find My Mac works normally again? Any suggestions on the battery issue?

Current OS: High Sierra 10.13.6

Thanks in advance!

MacBook Air (13-inch Mid 2013), OS X Yosemite (10.10.5)

The easiest way to restore power management settings to defaults is to reset NVRAM: Reset NVRAM or PRAM on your Mac - Apple Support

... this deactivates Find My Mac while sleeping.

Yes it would. Reset NVRAM first, then make a determination regarding your MBA's power consumption in sleep mode.

Hey,

I'm facing the same issue. Battery usage has gone up significantly specially drain when in sleep mode. I was running on 10.13.5 and noticed this excessive drain in the last 2 weeks. I updated to 10.13.6 today but the issue persists.

I later realised that it might be an issue with chrome and not macOS as there was an update to chrome in early-mid September, which is around the time i started noticing this issue.

Are you also a chrome user?

Regards,

G

I'm having this same issue. I just noticed it two weeks ago. My battery levels have drastically depleted. I'm using Firefox primarily. I've done everything I can to adjust the levels and conserve energy. I have a MacBook Air 11" early 2014 (OS X El Capitan version 10.11.6). I love my Air and I don't want to trade up for a new model just because of a battery. Any suggestions?
