I bought my 15' MacBook Pro in August of last year, and the battery is already down to 82.7% of the capacity. It's only had 142 full charging cycles. Should I get it checked out? My old 2012 MBP took about 7 years to get to the same capacity.
I have AppleCare. But Apple says it shouldn't reach 80% until 1000 cycles, so I'm a little concerned.Battery needs to drop below 80% in order to have Apple replace it.
Do you have AppleCare on your MBP ?
Battery design has fallen from the old days - agreed.
My 2015 MBP 15" has 85% even after 5 years.
But the 16" MBP less than a year old is already at 80% at 75 cycles so I am quite disappointed as it was a pricey model ($2500).
Same here - I am quite shocked to see the 16" battery drop so much over 11 months of use and very low charge cycles (sat on a desk as a desktop for most of it's life).I have AppleCare. But Apple says it shouldn't reach 80% until 1000 cycles, so I'm a little concerned.
I use coconut battery. But the weird thing is I didn't have battery degradation issues on my old MBP on intel, so I'm hoping it's just a battery issue that doesn't require me to replace the entire laptop.Same here - I am quite shocked to see the 16" battery drop so much over 11 months of use and very low charge cycles (sat on a desk as a desktop for most of it's life).
What battery monitor app are you using ?
I think it's a thermal degradation caused by the heat of the Intel CPU.
My 16" runs super hot all the time while the 15" runs lukewarm....
I believe that if you were to switch over to the M1 which runs cold - the battery should last a lot longer.....
What app does Apple use to measure battery capacity ?Coconut Battery readings never agree with one's laptop's reading %s or those taken at Apple stores. My laptop is at 77% with 800 cycles. Approaching battery replacement territory.

Isn't anything under 80% replaceable under warranty or applecare ?
I don't think that is out of the ordinary, having low cycles doesn't mean a better battery and the same thing goes for high cycles meaning its a bad battery. I'm guessing it could be from the heat from usage and having it plugged in all the time.I bought my 15' mid 2018, and the battery is already down to 85% of the capacity. I am at 43 full cycles.
What is the difference between optimized battery charging and manage battery longevity?If you are on Catalina or Big Sur and have Battery Health Management on, turn it off and the battery health should rise to a higher level.
maybe... but the laptop is randomly discharges from 100% to ~90% when pluggedI don't think that is out of the ordinary, having low cycles doesn't mean a better battery and the same thing goes for high cycles meaning its a bad battery. I'm guessing it could be from the heat from usage and having it plugged in all the time.
Optimized charging learns your laptop usage and waits to charge it to 100% until later. Like if you leave it plugged in all night, to will go to 100% at like 4-5am. I’m guessing longevity is just artificially lowering capacity, that’s what Battery health management does at least.What is the difference between optimized battery charging and manage battery longevity?
Thank You
Definitely thermal heat related!I don't think that is out of the ordinary, having low cycles doesn't mean a better battery and the same thing goes for high cycles meaning its a bad battery. I'm guessing it could be from the heat from usage and having it plugged in all the time.
both bad for the battery, even worse if combinedI don't think that is out of the ordinary, having low cycles doesn't mean a better battery and the same thing goes for high cycles meaning its a bad battery. I'm guessing it could be from the heat from usage and having it plugged in all the time.
