How to kill my Macbook Pro external card?

[huffy15]

Hello, I tried many times to completely disable it didn't work. I was looking for an efi solution. I'm working all day on the battery and because of the Radeon Pro 450, I'm currently recharging my macbook pro 15 2016 3 times a day. I never encounter such a dispute with Apple. Apple care erased my whole computer and it changed nothing. My battery life is awful (less than 3-4 hours).

I regret a lot my purchase because of this issue. I'm only using photoshop and Chrome. I just need a 15 inch laptop with a 8-10 hours battery, but it doesn't seems to exist anymore.

"You can quickly determine if the issue is related to your graphics processor or driver by following these steps:

"Disable the GPU to quickly narrow down the issue

1. Launch Photoshop.
2. Choose Edit > Preferences > Performance (Windows) or Photoshop > Preferences > Performance (Mac OS).
3. Deselect Use Graphics Processor.
4. Quit and relaunch Photoshop."

No laptop is going to give you 8-10 hours battery life if you constantly use applications that trigger high-power GPU state. Using the iGPU here is also not a solution: its power draw is not that much lower than that of a dGPU. What would solve the issue is asking the application developers to release the performance-critical resources when the app is idling (but good luck with that).

He might get an hour more "maybe" if he followed those steps.

Use Safari.

Use Safari.

I can't. I'm Front-end developer and I really need the chrome inspect element :s

I actually tried the 12inch 1.1 Macbook and I was averaging 8 hours. (Photoshop + Chrome)

Learn to use the Safari one?

Chrome will kill your battery, so if you do use it, it will be less than it would be if you used Safari. I like the Chrome tool myself

Yes thx, but that's a big learning curve I'm not sure for now
