Due to the design of the case, the bottom has bowed out from temperature changes, but the battery is fine.
Shame what they did to the new ones. I ended up getting a Razer Blade 13” to use at home, which seems tantalizing close to what new MacBook Pros should be.
There’s no where for the metal to go when it expands and contracts during temp changes, so it bowed out, in its little creviced area it fits in. Nobody told Apple to surround metal with metal or how apparently.
It gets down to freezing sometimes, always shut off and I warm it up to room temp before turning it on, 8 or so hours.
How does your MacBook Pro work after being repeatedly frozen? Or sitting in a hot car? If you don’t do this, you wouldn’t know.
