I have Apple Care+ and wanted to find out if Apple would replace my MacBook Pro Retina Early 2015's battery? I have 446 charge cycles on it right now. I am not sure if the stat reset when I had to factory reset my MacBook about a year or so ago. Thanks for the help.
 
It says 88.9% on coconutBattery FYI. So should I hold off on my battery replacement in my laptop?

That's not bad at all. Are you getting any battery warnings? If not, you may want to wait until you are closer to the expiry date of the Applecare.

No battery warnings, but it also doesn't help that Apple took out the estimated time remaining portion in some past update. Not sure if they brought it back yet.
 
They will NOT change it due to your large number of cycles, that is your use and no reason for them to change it. However, if your battery health drops below 80%, they should replace as premature wear. Based on what I found they warranty 80% capacity during AppleCare+ coverage period. Also, Apple quotes 1000 cycles as normal for the battery (I assume before it should drop below 80% capacity). So check wear on battery and if it is worn out more than they say, ask for replacement before warranty ends.
 
Others are correct. Apple considers a battery to have failed when it holds less than 80% of its design capacity before it reaches 1,000 cycles (after which it's considered consumed, not failed, and is not covered).

Just bought a new 2015 MBP. Will get 3 year Apple Care.
So should I go easy on the battery (leave it plugged in all the time where possible) so it has fewer cycles and lasts longer?

Or try to use it to death, and try to get below 80% before the 1000 cycles/three years? So it gets replaced.

Don't worry about it. Just use it.

2015 13inch bought March 2015. Had only 71 cycles on the battery (stays plugged in). Battery bloated 2 weeks ago. Apple replaced it and the top case-keyboard-trackpad for free. Batteries shouldn't do that with only 71 cycles.

Nah, don't worry. The battery is quite durable whether you baby it or not. It's a notebook after all, you're supposed to carry it around and use it wherever you want.

Batteries fail in all sorts of products all the time, apple sorted it under warranty so I can't see what your issue is. Age is a much bigger killer of lithium batteries than cycles anyway.
