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.

Apple is not run by Steve Jobs anymore. You are using an HDMI adapter to drive a large an external monitor. Apple is now run by a different breed of people who are corporate oriented rather than consumer oriented. So expect to pay more for less and only get six years of use out of it. If you don’t like this then support the Right to Repair people and legislation.

I’ll be very happy to tell you just how little you have to spend to get that old machine up to speed if you’ll tell me what it is. ( It’s probably a better machine and better built . more upgradeable and repairable).

I've still got my old MBP 2014. Got twice the battery time connecting to the same external monitor through the native HDMI port as this new 16-inch model using USB-C adapter. Nothing wrong with my old machine. In day-to-day use it is plenty fast (16 GB Ram/1 TB SSD/4 GB Video Card). I know how to mod. I was just wanting to upgrade to the faster processors, graphics, etc .... and sell my old machine while I can still get value out of it. Haven't sold it yet. :-)
