Battery performance on High Sierra

Hi,

I was finally able to solve my battery issue...

I figured out that was... wait for it... Intel Power Gadget which cause iGPU draining power. The same program which allowed me to know that iGPU was incriminated !

I uninstalled it (in a long process in uninstalling et re-installing programs to determine the power-angry one), and my autonomy is back again, mission control or not !

As I write these lignes, activity monitor says 10:14 hours battery life left !! Awesome !!

Good luck in finding your battery issue cause !

Rémi from France.

Yep, that was Intel Power Gadget... Initially, I installed it when I received my mac in january 2017, but I update it when I upgraded to High Sierra, 3 weeks ago. That was when battery issue started...

Hi Zyg4,

As I look to your screenshot, Safari and Seamonkey are draining power (a lot).

Is Seamonkey a background program ? In this case, it should be not have a 15+ energy impact !

Try to uninstall it...

You can also try to sort activity monitor by Energy impact (clic on the top of column "Energy impact"). So you'll see which app are power-angry.

About your activity monitor, how did you put the "Avg Energy Impact" column ? I don't have the option in mine, and the informations provided by this column might be decisive !!

For the record, it seems that my battery life is even better with High Sierra (without Intel Power Gadget). 4h+ lite activity (browsing, powerpoint, word, youtube...) at mid brightness >>>>> 58% battery life remaining (6:20 hours).

I am starting to think this is an (Apple) thing. In the past I used to love updating because you knew that you would be getting enhancements to your products. With apple this is now a technique to destroy the product so you can go to a specialist and have them tell you about a newer faster system. My 2014 Macbook air gets 13 hours battery. I made the update and instantly it went to 4/5 hours. Come on Apple ! They could have a group of 10 testers to tell them its an issues its simple. I don't believe they care. updating will end up being the end of Apple and its former popularity.

Yes, I have The same computer and issue. after installing high sierra the battery performance has gone down the toilet i use to get 7+ hours now I'm down to 1-2hours on high sierra =(

The same thing happened to me. Apple has to solve this with another update asap. Its so bad this way. My macbook air used to last around 11 hours but now it only lasts 8 hours.

Come back in a few days and confirm this. I think you will find it is a temporary situation caused be the need to index more than is usually the case.

I tried an SMC reset but there was no change to the battery life 😟

So it must be software related. I will never ever update in this case. Probably they'll fix it with a patch or with upcoming updates but I can't take the risk 😟

Having the same issue on my early 2015 MBA

I've reset the SMC. And the results are virtually null: in 2 hours, I'm down to 17%.

Same discovery!!!! My Macbook just loose very FAST now the battery life !!!

I got the same problem. My Macbook pro is now also shutting down at 11% and when I plug it in it's on 10%. My battery life decreased enormous.

MacOS in indexing your drive this is going on right now with my MacBook and will stop in about 1-4 days depending on how big your drive is normally I get 4-5 but when indexing I get 1-2

Excellente nouvelle Remi. Donc ce fut le mini programme d'Intel? wow. Ca n'aide pas les autres par contre, car j'en doute que tout le monde l'ont. When did you install it initially?
