1 Sleep Mode and Date Problems
My trusty 15” MacBook Pro mid 2012 had finally reached roughly 1000 cycles on the battery and was starting to not hold a charge for much longer than 3 hours. I ordered a replacement battery back at the end of March of this year, but then started having strange random problems with my macbook dying during sleep mode and randomly losing the date and taking longer than usual to boot.
I’ve tried resetting PRAM and SMC to try to fix this issue, but that hasn’t helped.
I would suspect the battery I’ve replaced it with from iFixit, but Coconut Battery seems to say my battery health is good. Only recently, I’ve run a check again and it seems to say my battery health status is “failed” even though it seems to run fine when it’s on. But that’s only so long as I don’t put the computer to sleep and let it sit in that state for very long.
Is this a battery issue, or a logic board issue?
Update (10/29/2018)
UPDATE: The problem ended up being a bad battery. iFIXIT was nice enough to send a new one and so far a few days after installing the new battery, I have yet to have any issues whatsoever with sleep or losing the date. Coconut battery now also shows none under battery failure.
Bummer that they sent me a bad battery to begin with, but great customer service and warrantying a product I purchased back in March. Thank you iFixit!!
Is dit een goede vraag?

I see you are using macOS Mojave here, please tell me you have backed up this computer... who knows it could be a beta software problem for the slow boot up time and the date. Assuming by the description of your problem this has started occurring with the new battery?

@ajcooke01 Yes, full time machine backup including my most important files backed up and saved on a dropbox account.
The problem existed before I installed the beta, and has continued while using the beta as well.
