Xcode 8 high energy impact on nTB MBP

[Moosetwik]

Hey everyone. I've recently bought the above MacBook after using an iMac for Xcode since I started learning a month or so ago. Anyway, is it normal for Xcode to be a huge battery drain even when I'm not building or simulating apps? The average battery impact is 10.85 currently, and the estimated time remaining in activity monitor goes down to about 2-3 hours remaining on 90% with Xcode running. Is this normal, is there a setting I can use when on battery?

Xcode is constantly indexing and incrementally compiling etc as you code — it's a battery hog!

I get ~4-5hrs on my 15" MBP with Xcode though — have a look in the Energy tab of Activity Monitor and see if anything is triggering the discrete GPU.

The energy impact is primarily based on CPU load. For a two core CPU peak impact is around 400. So 10 is a fairly light load.

Look for the explanation elsewhere:
- high brightness
- externally connected equipment (display, usb disk, hub)
- other processes (spotlight, time macine, ...)
- or combination of all of these

The dgpu would normally be on the list, but as this is a ntb mbp you do not have a dgpu.
