Hi everyone,
I just replaced the battery of my mid-2012 15" MacBook Pro for the first time. After calibrating it (steps I took below), I checked the battery with coconutBattery and It's showing that the design capacity is around 88%-90% after only 1 cycle. This isn't normal, right? I didn't check the battery prior to the first cycle.
I've read that coconutBattery's percentages fluctuate because of error margins, so was just wondering what y'all thought. I don't think it's dropping a bunch per cycle, instead, I think it just came missing the 10% charge like its been already used. I did another cycle and its now at 88.1% as I'm writing this (7457 mAH/8460 mAH). Not too knowledgeable when it comes to batteries and their capacities. I have warranty, so should I return it? I attached an image of the coconutBattery info.

Calibration process:
- After replacing the battery, plugged the charger in and turned on my macbook (was at around 86% I believe)
- Charged to 100%
- Waited a few hours
- Depleted to 0% until the computer hibernates/sleeps (was using it regularly to watch videos and whatnot)
- Left in down state overnight so battery fully drains
- Charged to 100% again the next morning
