Battery degrading really fast on newest MBP 15 TB

[nonm]

Before the new update i was on 101.4% capacity. Yesterday i was on 100.3% and no im already at 99%. Anyone know whats the cause?

Normal variation of readings.
You are watching it too closely. 😀

If it drops 7% or more after a week, then you should ask Apple about that.

Looks like overall people are not too happy about the battery in the 15" 2016 rMBP !

Does Coconut Battery show different figures from the value in the About This Mac system report then?

My 15" MBP TB shows Full Charge Capacity (mAh) 6952. (With 6 cycles) If your figure there matches what Coconut's saying it sounds a bit low?

Battery technology is as far from an exact science as you can get. It's not digital. Lithium is a clumsy, bloated beast, that will slowly decay from the sands of time alone, even if it had never been charged once.

Battery health can give a different reading based on how much charge you currently have, how accurate the OS is interpreting the capacity, or even how warm your laptop is. This is partly why you shouldn't worry or question 99% 'health', as much as you did for 101% health...

If real-world performance and battery life drops by a significant margin, then sure, check Coconut. Otherwise you'll just be fuelling your own paranoia and impact the enjoyment of your laptop in the process.

Well tbh my battery was being exceptional after the new update.

Only within the confines of the internet echo chamber.
