I have a 3 month old 2018 MB Pro 13" and noticed after only 10 lifecycles that my battery (based on the Battery Health app) shows my battery at %99. When I occasionally disconnect my power source and then reconnect it goes back up to %102.

Anyway although these apps are an "estimate" or at least I think, if I ordered an iFixit replacement would "that" battery be stronger, the same, or less powerful than bringing this to Apple for repair?

I don't think at this point its worth it but just curious from people who are more savvy at this than me.

Thank you!
 
Apple OEM batteries are the best. And.. I don't believe there is anything wrong with your current battery. However, since it's still under Apple Care, make an appointment with the genius bar and have them check it out for you. By the way, your battery is not user replaceable in case you were thinking about doing it yourself.
 
Thank you, used to being able to replace it....just ODC kicking in here. =)

Obsessive Disorder Compulsive lol Well you do sound OCD, I would not be worrying about your Apple laptop battery for a long while. Don't panic when it finally hits 95%, you're still good.
 
Third party batteries are almost always worse regardless of device being spoken about in my experience.

Also, a battery is not expected to remain at '100%' for very long, they naturally degrade, and that is not considered a fault unless it's excessive, which by apple is defined as drop to 80% of max capacity usually, or suddenly dropping in a big step or turning off when not at 0%

There is nothing wrong with your battery.
Repeat, it's fine.

Take it to an Apple Store genius bar and let them check it out.
They're gonna tell ya the same thing I just did.

Order a new battery now? Why? There is literally NOTHING wrong with your current battery.

The battery health degradation is not linear and you do not need to worry about it until you're noticing problems like severely reduced battery life or the OS tells you to worry about it.

Also, buying a battery now is a really bad idea. Lithium batteries degrade just by sitting there doing nothing. So you don't want to buy one early as you'll have a degraded battery in 2+ years when you aim to start using it. It is always better to buy them when needed and be sure the battery is very fresh and not old stock.
