Is anyone *actually* getting 10-11 hours of battery life on MBP 16?

Waaaiiiit a minute ...

Standby on this one.

It appears I will need to see this particular test through. With possible egg on my face at the end.

I'll buy your Macbook if you don't like it....

So far I'm at 1 hour and 45 minutes of use with 87% remaining.

I feel like a patient whose symptoms magically disappear at the doctor's office.

Will continue to monitor, doc.

Something has to be wrong ... probably software or maybe hardware.
I have the standard config on which apple did the battery test (2.3 i9, 5500, 16gb/1Tb) and using it for browsing (7-8 tabs in Safari), email (Spark), text editing (MS Word) WhatsApp and Onedrive always connected and screen at 70% brightness I can obtain without issues around 8-9 hours of battery life.
I did not have any custom config, no turbo disabled or igpu forced on.

As an aside, if you are still using Apple's Mail, now may be a good time to ditch it. I had it trying to index emails at one point and that caused my fans to max out for a whole hour. That also did wondrous for battery life.

Use Spark or something else.

And for some strange reason, the fans would max out too when Mail was open and the Wi-Fi was disconnected. I have submitted feedback to Apple late last year but it’s still a problem.

Mail was definitely a resource hog for a really long time.

It continues to act up by failing to send out messages through my private domain.

I'll give Spark a shot. Never heard of it!

I'd say more like 3-4 hours. 10+ tabs of Firefox open... code window open, youtube etc.

Found this thread with a search and I'm having this issue. 16" that I bought at launch. 2.4 i9, 32gm, 2tb, 5500m. It doesn't seem to matter if I use Safari or Brave, but just internet browsing with no video or audio I get 4ish hours estimate. Working in web dev, I get half of that - Node is a hog. I really expected more from this thing. I work at home, so I'm always close to an outlet but it is an annoying problem. It doesn't drain much when sleeping, just excessibly during light usage.

Later today, I'll try an SMC and NVRAM reset. I do have automatic graphics switching on. On Brave and Chrome, I have a tab suspend extension that sleeps them after 1 hour so they don't hog resources. I don't use Apple Mail, I use Postbox.

Found this post on the Apple forums. Maybe I'll do a full reinstall from scratch for Big Sur. https://discussions.apple.com/thread/251206230

This thread isn't really selling this model to me. I've been looking to upgrade my 3-4 year old 13", but I'm still getting around 6 hours battery life doing most of the same things that get most of you 3-4 hours.

 

[Silvestru Hosszu]

Not everybody has issues.
See my previous post (#53).
Three months have passed and the situation is the same.
For quite serious office work with brightness well above 50% (usually at 70) I can effortlessly obtain 8-9 hours of battery.

I've had my 16" MBP since early February. I absolutely without a doubt get the quoted 11 hours of battery life without issue. I know which apps use the dGPU (such as Pixelmator, FCPX) so they will drain the battery faster and I also know which apps are major resource hogs (CHROME) so with that in mind I understand what it takes to get the 11 hours that Apple advertises.

 

[nudoru]

My issues are likely apps using the dGPU more than I'd like and something carried over via migration assistant. I've migrated between 3 different laptops over the past few years.

@jbachandouris this is a great laptop. I love it more than any MacBook Pro I've owned. I highly recommend it.
