So many people -myself included- report that their 16" battery health is less than 100% out of the box. Now that'd be okay if it was 99 or even 98. But for most, it's 95% or even less. Now that's all fine and dandy, discharge and charge and let it calibrate, it'll be fine and report correct readings right? This seems to not be the case for everyone.
My 16" (32GB of RAM, i9 2.3 CPU, 1 TB of SSD storage) came out of the box with 99.7% battery health. Didn't complain, altho I don't remember seeing a MBP with less than 100% battery capacity out of the box. 11 cycles later it drops to 97.8%.. I thought maybe it was a fluke and it would settle later, so I let it drain to 0% and then charged it to 100% and left it plugged in overnight, but unfortunately that didn't help. A few cycles later it got worse, yes worse. Down to 94.9% now at 40 cycles. I tried "calibrating" it again multiple times and nothing seemed to work. I even reset the SMC, the NVRAM, and PRAM multiple times to no avail. I eventually wiped it clean and installed macOS and didn't restore from any backup. Still, the issue persists.
I took it to an authorized apple service provider since we don't have Apple Stores where I live, they ran diagnostics on it and told me the health was 97% on their test which was normal to them... 3% degradation in 25ish cycles damn apple?
I made a couple of posts here and on Reddit, and I found out that I wasn't alone OCDing over this.
My battery manufacturer is Simplo -you can check yours in coconutbattery-, and I realized most other 16" with these batteries have a similar issue/pattern. While DSY batteries (the other manufacturer that makes them) seem to always have a 99%/100% battery health out of the box and even up to 40+ cycles. Although I saw very few DSY batteries with a similar issue to mine.
A lot of people told me these readings are all guestimations and whatnot, but if that's the case; why does it decrease in my case and many others? and why isn't it 100% like other 16"s at all? Not even once has it hit the 100% of design capacity.
I'm way past my 14 days return period since this all happened afterwards, and none of the apple support workers know ******** about this tbh... Got this mac a month after its release.
So yeah, thoughts guys? This issue has been nagging me since its inception, it's been triggering my gadget OCD you can say.
