How's everyone's battery life on the final version of Mojave? I'm using a 2015 Macbook Pro and worried my battery life will be terrible on Mojave. So far it's great on High Sierra.

Sleep is way worse so far in my experience.

High Sierra was bad, I might lose 10% overnight. Mojave said “Hold my beer...” and I seem to lose 30% overnight.

I haven't had any issues. In fact, under High Sierra I used to lose more battery overnight than I do now under Mojave.

Also, I gained about 20GB of SSD space back.

my battery life improved drastically. Its TouchID I'm not too happy with now. Sometimes it doesn't read and I have to hold it there, where as before I could briefly touch it and it would read and unlock. Feels like it went backwards

Not too bad on my old Mid 2012 MacBook Pro. This used to be on High Sierra and I do not see any difference now that it is on Mojave.

I haven't had any issues with it asleep or turned off. But when I'm using the machine, it seems to drain unusually fast. It takes a long time to boot up and for apps to load, so I may roll back to Sierra. Mid-2015 13" MBP.

Installed 10.14 on a separate partition on my MBP late 2015. Charged the MBP up to 100%. Logged in, removed the power cord, and put the MBP to sleep. Started the timer on my iPad and woke up the MBP after 7 hours 10 minutes. I still had 100% battery.

I did not want to believe it and just for the heck of it, restarted the MBP, but I can confirm that after 7:10 hours of sleep it retained 100% battery power.

I reset the NVRAM and left the Macbook at 18% at 12:00 AM. Woke up at 10:00, the battery is at 14%. So that's an improvement: 4% drain vs. 25% that I had before. I suggest everybody try a NVRAM reset.

Thanks. I tried an SMC reset and no dice. I'll try this.

My 2015 seems to sip battery while I’m using it but I picked it up yesterday after it had been asleep from the previous day and it was warm. Power nap on battery is disabled. Further research needed on what it’s doing while it should be sleeping.

Yes, exactly what happens to mine. Warm all over when sleeping....
