use "Sentence case", e.g. "Data Saver enabled" with a lowecase "e". That's the
Android platform default, and we use it consistently in Chrome for Android.

I'd add this at the top of this file under the "generic strings" section (and
make the description general, of course). Also, you probably want
[CHAR-LIMIT=20] since this is button text. (See the CHAR-LIMIT guidelines at the
top of this file.)
