I have the base model MBP 16 inch and I've been experiencing slow downs with laggy keyboard input, momentary freezes, etc. Battery life is also not as good as on my old MPB 13 and I don't use it for much more than browsing with many tabs. I've done plenty of troubleshooting and a reinstall but no luck.

I'm hoping that 10.15.3 which I installed yesterday will help remedy.

I have been having similar issues with freezing, but only the video stutters, everything else keeps running in the background. I also have the base space gray model.

Weirdly enough this only happens if I don’t turn off the mac for days (only putting in sleep mode) and when the ram is close to 16GB.

However, when the ram gets to 16GB, the only thing that gets impacted is the video, there is no spinning wheel, audio doesn’t stop. Just the video stutters for a bit, then jumps to present.

The theory here is that the onboard graphics card doesn’t have enough ram for it, it is being swapped constantly, which causes the stutters.

I hope a system update will be enough to fix it.

Edit: adding “no” to spinning wheel

You didn't restore from an old Time Machine backup onto your rMBP right?

If not, it sounds like a defective unit. I'd strongly recommend taking it to Apple Store.

I had no issues with laggy keyboard input, freezes and battery life was very solid for me. I've returned the laptop not because of these issues but because useless touch bar and large trackpad on top of Catalina issues.

This happened to me a year back. Turned out there was an issue with SATA cable connecting SSD. Replacing the cable resolved it. Saying just in case!

There could also be an issue with your SSD or HDD. To come to a conclusion try putting your SSD to another MB and see wheres the issue

The SSD is soldered directly to the logic board, so that may not be a viable strategy.

It’s also not SATA. Not that it matters.
