I juste noticed in coconut battery that my battery is currently at 87% capacity on a laptop that has 106 cycles and was bought in January 2020, is this a normal degradation ? If this continues on a linear path, I am looking at lower than 80 % design capacity at the one year mark. I brought the device to get Applecare+ on the pilot program and while running the diagnostic the tech said everything is alright. He commented that the battery seem to still be good, being at a higher than 80 % capacity.
This is a 8 months old device, last month the computer showed 91 % capacity and even then, I think after not even a year of usage that seems like a pretty quick degradation.
Is this the norm ? Its on a 2019 2 TB i5 MacBook Pro.
It is absolutely not correct behavior. I have a 2015 MacBook Pro, now granted it is plugged in most of the time, but I got my 2015 in May of 2016.
According to Coconut Battery, I have:
2015 13" MacBook Pro:
57 cycles
95.4% Battery Capacity
2019 15" MacBook Pro:
15 cycles
99.6% Battery Capacity
2019 16" MacBook Pro:
12 cycles
99.8% Battery Capacity
I'll have to get back to you on my MacBook Air.
This is what Apple's policy used to be. It still may be:
"Your battery is designed to retain up to 80% of its original capacity at 1000 complete charge cycles. The one-year warranty includes replacement coverage for a defective battery. Apple offers a battery replacement service for all MacBook, MacBook Air, and MacBook Pro notebooks with built-in batteries"
I know you will not get to 1,000 charge cycles by January, however, if that battery drops below 80% by or before the specific date you got your MBP in January, it should be changed by Apple at no cost to you.
Hell, if you take it to an Apple Store and get a cool Genius and/or Manager, they might do it for you because that is certainly not right unless you are abusing it.
Like someone else said, are you letting the battery discharge below 20% or even all the way until it dies and then charging it right back up? As he said, that is not good at all for your battery! Do you keep your MBP in a relatively warm or hot area? That will cause issues with the battery when it discharges and then recharges, or even if it is just plugged in. Heat is the enemy of these types of batteries. That is why I am against wireless charging and fast charging. I charge my iPhone 11 and 12 Pro Max with the old tiny white cube, or an iPad charger. SOMETIMES, if I really need my phone charged then I will use my Apple Fast Charger.
When did you take it to the Apple Store and have the diagnostics run on it? It might be time to take it back to the Apple Store and tell them that your battery appears to be degrading very fast since your last visit with them.
That is really all the advice I can give you. Generally, if you take great care of your stuff (especially Apple products) they will last a long while for you, the same goes for your car and many other things. There are defects, which you might have but you will have to prove that to Apple.
Sorry for the long post!
