Just got a new MacBook Pro 16" and today is the first full day of use. I am getting less than 4 hours of battery life, not even close to the advertised 11 hours.
Will do more testing at work tomorrow and hopefully things improve.
Config is 2.4GHZ 8-core, i9, 32GB RAM, Radeon Pro 5500M 8GB
MacBook Pro 16", macOS 10.15
Partially figured it out (for me at least)
Station (getstation.com) was forcing my discrete GPU to run all the time and eat up all my battery.
Open it using terminal with this command: `open /Applications/Station.app/ --args --disable-gpu`
and your battery life life goes from about 3 hours to over 5 hours.
Still not even close to a full day, but much better.
I have exactly the same problem
Well...if they make us pay 3300 euro for a machine that has a Garbage battery capability...or if have to use it at home so i would take an iMac not a MBP 16....and say its worth 2 Trilion....
Seeing this issue too. From 100% to 38% in one hour. Obviously a defective product.
Hello guys, who updated mac with the recent update?
I noticed my battery no longer drains that fast.
What update?
10.15.7
I have a NEW machine coming in on the 4th of August to replace this one. I have added the two menu bar add-ons above. One allows the CPU Turbo Boost to be turned off which helps and the other allows you you to stop the graphics card switching. I have noticed when ONLY using the laptop itself (no external monitor) with these two items the battery life is greatly improved but still doesn't get 11-12 hours. I have sent several replies to Apple via /feedback with no response yet. I'm greatly concerned about the machine I pid almost $5k for the has such inefficiencies.
Others have reported an SMC reset helps new Macs see a better battery runtime. See this:
How to reset the System Management Controller (SMC) on your Mac - Apple Support
Your MacBook Pro has the T2 Security chip. Make sure you use the special instructions in that section.
The issue for me comes down to the dGPU v iGPU. The Energy preferences should be:
(1) dGPU on
(2) automatic switching
(3) dGPU off
If I’m rendering/exporting video or gaming: yes to 8 GB dGPU being on. If I’m just working in other apps the 1.5 GB iGPU is fine.
Some apps that don’t need it at all engage the dGPU (eg. Spotify) so that’s a developer issue.
The whole idea of having a dGPU is speed up graphics tasks and take stress off of the CPU. Really that should create more efficiency somewhere, but it definitely isn’t in battery drain.
I don't see how is possible define someone "rude" if you don't hear the voice. From a text you can give the interpretation based on your mood, that's all. But this is not important for the moment.
It seems that you are reading only what you want into the messages. Why don't you answer this?
However, as I said in the beginning of this thread, mine drains 1% battery every 2 minutes with brightness 70% and nothing open. All the applications killed, only showing the desktop. This is far away from the 11 hours, and I challenge anyone to say that it's not true.
You've extracted only the convenient part for you. Please copy and paste the whole phase, which makes more sense.
Same config.

Is it normal for battery to be <97% of design capacity after only 15 cycles?
Previous machines I have had have been at 100%+ during early use.
"Running office apps, through a browser - the battery has gone from 100% to 60% in an hour. 40% drop in an hour. Looks like i'll be recharging again in a few hours time. "
Always check to see if the dedicated GPU is activated. If it is then you will not achieve the advertised battery life because the dGPU is high performance which uses a great deal of system resources. You can verify if the apps you're running are activating the dGPU by going up top to the Menu bar-About This Mac. Look at what's listed next to Graphics. If you see the Intel Integrated Graphics 630 and the AMD Radeon 5000 series GPU activated then that's why your battery is draining.
If you're running Chrome it will drain your battery since it's a system resource hog and it doesn't need to activate the dGPU to still pull on battery a great deal.
Be sure to leave the power adapter connected all night. You want your MacBook Pro mostly-charged most of the time for long battery life.
Best practice is to use it on power adapter when AC power is available, and otherwise use it on battery BUT do not store it overnight or longer in a discharged state, if possible. Never leave in a hot car.

The Apple USB-C Multi-port Adapter AV used to connect HDMI external displays has a warning NOT to leave it connected when not in use -- it will drain your battery:
Because this adapter draws power from your Mac or iPad Pro even when your Mac or iPad Pro is asleep, you might want to unplug it when it's not also connected to power for charging.

<<Now, the other issues I'm having are: >>
There appears to be a flaw in the latest software that brings out the WORST in the graphics chips -- crashes on wake from sleep.
The work-around is to disable Power Nap. Then if no joy, disable the top item in the red box:

Even if I restart the laptop after a full charge and just run a single browser window I get about 2 hours of battery life, and once it drops below 50% It accelerates. If I forget to close the screen and it’s not plugged into power it will still drain to zero in 2 hours and that’s with a black screen and no interaction. Took the laptop to the store and it tested at 98%. They said because of the design of the laptop a battery replacement is a major operation. For A $5.5k laptop it’s astonishingly poor performance.. I’m an app developer so I got 64 gb of RAM to make it future proof, but the battery isn’t event present-proof.
