Found huge activity from Google Chrome reporting errors

Aug 16 01:22:29 myMBA Google Chrome[18176]: objc[18176]: __weak variable at 0x600001228a50 holds 0x2121212121212121 instead of 0x600000c279a0. This is probably incorrect use of objc_storeWeak() and objc_loadWeak(). Break on objc_weak_error to debug.

and Google Software trying to do update on repeated basis?

Closed Chrome overnight, still the same.

More investigation (and it repeats following every 30 second all night long):

Problem remains, something is draining the battery. How can I prevent this drain from happening?

Best Answer

Finally, I got it to obey when I say sleep !

The battery remained at 100% charge after 8 hours of sleep.

This is what sleep should look like between 1AM and 10AM. That's it, no other activity as it should be.

So what did I do? First it killed the pesky GooleSotwareUpdate (as described here) Pesky Google acting up .. that was active all night long and completely ignoring my sleep request. Then I shut down all apps (especially the Google Chrome that was misbehaving). Then I Left the Lid open and used the Sleep now command (in Apple top left) The reason for Lid open was to see if monitor comes on after a while, and it did ! I had to use the Sleep command 3 times, since it came back on about 3 seconds after ?
