Why is my battery draining fast with HDMI adapter?
My new 16 inch MBP battery drains very fast with an HDMI adapter. Of course now, you have to use an HDMI adapter with all USB-C/Thunderbolt ports. I am a college instructor and would plug my MPB into the AV system using the native HDMI port on my 2014 MBP, projecting to a very large classroom monitor. I could get about 2.5 hours use with my old MBP. With the new MBP, using the adapter, I’m getting 1.5 hours at best. Occasionally less. Running the same apps, processes as I did with my older MBP. The new MBP supposedly has a bigger capacity battery so it should give me at least the same battery time as my older MBP that is 5.5 years older! I am using an Anker USB-C/HDMI adapter. I don’t think that should make a difference. I like Anker cables MUCHO better than Apples crap and overpriced cables. Thanks for any advice.
Is this a good question?
