Update:
Got my MacBook 2015 back from getting a battery replacement at Apple. I took mine in before the price increase...
For me it was worth it...but NOW...with the increase of the cost for the battery service, the cost now makes it a hard choice...it really depends on how much you like or use the 12" MacBook. I do, so it was worth it to me.
With the replacement of the battery on MacBook 2015, Apple changes the bottom chassis since it is glued... My bottom before had no scratches on it, but the one I received back
looks really new. No one REALLY looks at the bottom UNLESS you use it in clam shell mode (I do...I am using it now when typing this thread.
)
Also...
an advantage of Apple doing the work..
My thunderbolt port was
really loose, sometimes causing my LG 24" UltraFine (Apple) monitor to sometimes flicker when I put it into the port. I got my MacBook used about 6 months ago off of Amazon cheap and the port was a little loose. Because Apple has to replace the bottom, the port (including the headphone jack - which was also little loose) was tight again after the service.
A bonus getting the service done.
I was hoping that Apple might redo the thermal paste while they had to take apart the unit...
but I seriously doubt they would do that as a favor.
After
now 8 years, the CPU
still runs really cool (to my surprise), so MAYBE the one (or company) that sold it to me may have re-done the thermal paste.
I bought it reconditioned. The keyboard, looked like it was replaced during the recall, for it look new without wear. I got lucky (or blessed) when I bought it on Amazon as I have heard horror stories about used MacBooks (2015-2017) bought on eBay and Amazon..it SEEM in great shape. The Genius at the Apple store who helped me was surprised at the condition of my MacBook 2015.
So far (the first day back today), it is running good, CPU cool and when I checked with a battery app, the battery (to my surprise) stated it was on its first cycle (I think Apple may be able to reset it...regardless), but....the app(s) test stated that
the battery was made October 15th 2022! less than six month ago! So it is considered a New Battery! The two battery apps I used said that my older battery was made in 2016 March (8 years old), so it looks like I scored!
For me...I am happy with paying for the battery replacement. For those who might NOW decide to get a battery service, you have to be aware that the price went up at least $50-$100 U.S. last week. I am working out of the U.S. now on business and got it done outside the U.S., but checked the current price during pick-up...
it now costs an extra $170 (approx. U.S.).
Before taking it in, I went to an Apple Service Center and had a bad time trying to get the battery replaced. I contacted Apple and they said that service centers cannot do this kind of battery replacement (glued). They said come into an Apple store and we will check it, and if they have a battery.
You have to bring MacBook 2015 in for Apple to check before they will let you know "if" they have a battery for it.
Conclusion:
If you are interested in keeping this little underpowered gem, then take it into an Apple store and have them price out the battery service. After hearing the cost, make the decision.
