Macbook Pro 2017 battery problem

I have a macbook pro 2017 about 1.7 years ago.


I feel like macbook have a battery problem

such as use time 6-7 hours from 9 hours.


I found when charge 100% my Full Charge Capacity is 5810 mAh and Charge Remaining is 5749 mAh (both should be 6669+-200 mAh).


My cycle count is 98.

I think It's more unusual than it should be.


I need to know. Is this case in warranty?


this is full power system information report.

I do not see a problem. I see normal.


The type of battery in your MacBook Pro looses capacity over time. Think of the analogy of a metal water bottle you carry on hikes. When new, it held 16 ounces when full. After a few years of hard use and falling onto rocks, it gets dented and the dents reduce internal capacity. Now it holds only 15 ounces when full and is at 94 percent of its original or "Design" capacity.


Where did you find the 6669±200mAh value? Apple doesn't publish design capacity values for its batteries but some third-party utilities can read them.


Your cycle count looks fine. I feel 2-3 cycles a month is sufficient to keep the battery working properly and you are doing almost five--good. Like muscles, these batteries need exercise and yours appear to be commensurate with your computer age. I wish I had a dollar for every post about battery problems I've seen here over the last 18 years that started with, "I don't understand! I never use it on battery power!"


I use Coconut Battery (https://www.coconut-flavour.com/coconutbattery/)† to view my notebooks' battery condition and it includes the design capacity. This is that app's report on my 2012 MacBook Pro I bought in summer 2013 that still has its origianl battery:


The design capacity for that model's battery is shown as 5770 mAh; it should be higher for your15-inch model. "Health" is current Full Charge Capacity divided by Design Capacity. Get the app and see why it reports for "health" percentage on your battery.


As for warranty even with AppleCare, Apple says a battery is still fine if it maintains 80 percent health at 1000 cycles. It would have to be under 80 percent and under 1000 cycles to get any warranty action based on a long history of reports here.


I can see you are concerned so, if what I've said doesn't give you comfort, by all means make an appointment with an Apple Store Genius Bar and have them evaluate. I am reasonably sure that they will also say you have a normal battery but peace of mind is important.


† -- get the app only from the developer's site I linked. Some unscrupulous download hosting sites offer it but are likely to give you the free gift of some nasty adware to go with it.

Also the manufacturing date is whacked. Shows the year as 2560! Not sure where that is coming from. The number of days appears correct. My copy of CB is the latest and the dates show normally and consistent with when I bought the computer. I wonder if something with Mojave is causing that. Mine is still at 10.13 High Sierra.


I've seen the status bar charge level and the C-Battery charge level vary before. I find that the two reports usually match after a restart. If not, do an SMC reset:


How to reset the System Management Controller (SMC) on your Mac - Apple Support


If that doesn't change it, then let Apple evaluate.

I take it from coconutBattery and attach coconut screenshot in this post but my upload image was gone for unknown reason.


this is my re-upload coconutBattery screenshot (capture at 2562-03-21 14.49.44):


you can see Macbook Pro 2017 model have Design Capacity much more than previous generation at 6669mAh.


and now 100% charge in past 8 hours screenshot (capture at 2562-03-21 22.44.27):



you can see coconut show as 95% charge but my Macbook Pro say 100% on the top right of screen.

and my Full Charge Capacity has decrease everytime.


I think It has a problem exactly.
