Battery draining fast after upgrading to High Sierra 10.13.2

I'm not sure any of this is going to help or is even applicable to newer MBP's Mid 2017 but it's worth a try, I'll explain why at the bottom

I went old school, restarted and did the Power Management reset, Command Control P R, let it chime 3 times.

Then a Command-S, then fsck -fy, then exit and let it start.

It's MUCH better, after 3+ hrs, down to 64%, with constant web surfing. Before all of this after the last update I was pushing 10% at 3 hrs. YMMV. It's still not as good as it was but it's better. I hope that they figure out what the heck happened with the last update.

Hi, I saw your reply and checked mine and this bothers me. I am based in the USA and I bought my macbook pro mid 2017 without touchbar and my Full charge capacity is lower than the other poster. Should I contact Apple for this? thanks. Here's a screen shot.

Just seen this post now.

I bought my Mac in November and honestly in the past 2 months of real use, I'm lucky to get 3hrs out of the battery.

I ordered online and picked it up from the store. ITS 100% authentic and I also have have close to the same numbers as shown above. I have a 13" with Touch Bar. I always keep my screen at 1/2 and only run one program at a time.

I have to say this gently, you understand, but was this a special offer or budget priced battery. The report you just sent tells me the battery is questionable. If it were an Apple battery I would immediately say, take it back under warranty for exchange.

The full charge figure of 4620 is little more than half of an equivalent Apple battery and after only 19 cycles, too. My battery was 8780 when new and after some 220 cycles it is stiii 7870

Looking at your name, I am imagining you are in India where there is a lot of substandard goods washing around. I also know Indian technical people are very reluctant to admit fault and sadly I don't have much hope you will get a refund.

Try to get it back to the supplier is all I can suggest. You can show them what I have written here.

I upgraded to 10.13.2 today and IMMEDIATELY my battery would last only 3 hours or so (previously, literally 7-8 with intermittent use). I also notice it heating up.

I have an early 2015 MBP, so battery is not a spring chicken, but it was perfectly fine prior to the 10.13.2 upgrade, so that is pretty much the culprit.

I'm hoping this is a short term issue whereby there is some one-time indexing or something going on; if it is just a defect, I hope it is corrected and an update comes out soon! In all the time I have had my MBP I have NEVER run completely out of batter twice in a normal day!

I’m having same issue with new refurb of early 2015 mbp13 also have upgraded the os to Same. The battery drain is too fast for a New Batt. Will check the readings next, new to mac Advise a good battery ulility Download?

Sorry, I'm attempting to sound smarter than I am. 😁

FSCK -fy does the same thing that your disk repair does, cleans up the garbage in your system. On startup you can hold down command s, you'll see all sorts of stuff scroll by, when it stops on the bottom you'll see FSCK not done, or something similar. Just type in fsck -fy, let it do it's thing, then repeat. It will tell you if it's done anything. When done type exit and it will do a startup and with any luck things will be good.

As a note, I'm getting the sense that the issue lies with Safari, nothing I can prove except when I'm looking at processes it's looking like it's using a lot of resources/energy. I have no basis/foundation for this.

I tend to keep a lot of apps open, Safari, Chat, calendar and maybe doing some audio work, all on battery power, hey, it's a lap top that's the idea of them.

But since doing the power reset and the fsck it appears to be close to ok.

Best of luck.

Noticed the same issue with my MacBook Pro mid-2012 after upgrading to 10.13.2. My battery went from fully charged to 10% in about 2 hours with only Safari running. Also the device was running very hot and fans were going loud.

I've opened the Activity Monitor and found that Safari was running on more than 100% CPU! I've closed Safari and switched to Chrome for browsing, and the device went back to normal operation, no heating, no loud fans and battery life went back to normal.

It seems that something went wrong with Safari with the 10.13.2 update. Hopefully that gets fixed in the coming update.

I did the power management reset and fsck and thought I saw some improvement, but it was incremental. Since "shutting down" Safari and using Chrome *so far* I am seeing dramatic improvement, but I need to see it over time to be sure.

Other than the battery issue, what do you think about High Sierra? I have held off on installing High Sierra on the mid-2011 iMac, and I'm glad I did after I heard about the vulnerability last year involving third-party apps https://www.macrumors.com/2017/09/25/macos-high-sierra-security-vulnerability/.

OMG, to enable this software you have to enter System Preferences, answer YES on two dialogues, and also enter your password. Then it may STEAL your not encoded things stored in the keychain (by default everything is stored encoded). I think I'm going to Windows now. This is just too much!!!

High Sierra is fine, This battery issue , for me, is gone. Last night when clicking the battery it indicated that Mail was drawing the most, I shut down mail for a bit, restarted it and it now, 12 hrs later is fine.

Agreed - exploiting the vulnerability is a bit of a long shot, but I like the idea of avoiding any vulnerability if I can help it 😬 .

I am also in no rush since

I have a mid-2011 iMac and I hope it can handle High Sierra.

I have a 2013 Mac Pro and noticed the same battery drop issue
