After 3 hours of using the Terminal app the battery dropped 33%. 9 hours is what I got on the old MacBook Air. Not seeing any battery benefits here at all.

Wow, maybe Dropbox is the culprit?

Well duh, if you have a process that eats up CPU power like this, three hours is actually amazing. An Intel Mac would be out of juice within two hours top :) I guess this is the problem with these M1 Macs — they run so quietly that you can't actually tell if an app went rogue...
 
Dropbox is not a M1 native app yet.. but there must be another reason that its consuming so much CPU. But yes, that's the reason for your poor battery life

They have a build for it:

Probably using Rosetta though?

actually in the comments they then reference using this beta build on Apple Silicon:

 
If you are doing a synchronization with many files to download or upload, it is likely that Dropbox will consume a lot (of CPU, energy) in the process of doing so.
I do not have any M1 machine, but I made a similar observation with iCloud itself.
 
Dropbox is and always has been a ridiculously bloated resource hog.

It and Chrome are always competing for "who uses too many resources for no good reason"
I use Dropbox some but I never have it as a start up item because it’s always a battery hog. On M1 it’s even worse at the moment. I manually run it if I have any files to sync and then quit it once it’s done. I also don’t turn on the finder integration either.

I installed the beta Dropbox on my M1 MBP, but oddly it still lists as "Intel" in the activity monitor.
 
Started today at 8am .... was on a 5 hour zoom, ended with 75% ... played YouTube videos during the Zoom, and intermittent web sites throughout the day ... its 10pm now and im at 35% .... my 2016 MBP doesn't even come close!

Unfortunately I can't share the excitement :(

Just running Safari and mail client with a few apps open gives me around 6-8 hours of screen time. I roughly lose a 1% every 4-5 minutes. It's really frustrating! I did format battery twice now and I see no improvements. Also computer is already week old so all of the indexing should be done by now...

Any advice? Or do you think I bought a lemon?!

Thanks

What does Activity Monitor say? Check it for apps that consume high amounts of energy.

Something doesn't seem right with your machine, I've been smashing safari for 5 days, currently at 51% just under 6 hours usage. Base model M1 MacBook Pro here.

If you can't fix it via a restore, return it for a new machine.
 
MBP here, I am going into day 3 now without a charge, at 73% - Safari, YouTube here and there, a little bit of coding...amazing battery life!
