2016 Macbook Pro battery capacity degredation

[dmelgar]

I have a new 2016 MBP, 13", non-TB. I'm using CoconutBattery to report % of original battery design capacity.

When the MBP was new, it reported 108%, but quickly after the first few cycles it dropped to 97% and has now continued to slowly drop to 94%.

I normally wouldn't worry except that I've had bad luck with two of my last three Apple laptops. I had an original MBP that dropped to barely over 80% after 18 months despite Apple claiming 1000 battery cycle life. It was far short at just a couple of hundred cycles. I also have a MBA that dropped to 80% around 2 years. I still have it. It had dropped to 40% and I finally broke down and replaced the battery with an after market battery. After several cycles its still reporting 108%.

I also have a 2015 MBP from work. It has over 100 cycles on it and is reporting 97%, better than the brand new MBP.

Anyone else noticing strange capacity degradation?

Seems like there are a lot of issues with this computer. I am awaiting a new one as the first one had a sleep/wake issue. I will say that one came with 4 complete charge cycles already on the battery.

Have you tried a full battery cycle? Use your battery until your MacBook Pro shut off, then keep it charging until 100% and see if that fixed it?

This had happened with my RMBP 2012 before

Yes, I have run a complete cycle. Didn't help. It sometimes (rarely) reports as high as 97% but more often 94-95%.

Same here with nTB base, showing 96% around 4600mAH. Anyone else?

Mine fluctuates between 4650-4750

Mine has reported as low as 4469 (93%) and as high as 4601 (96%). 27 cycles. Keep hitting new lows.

The percentage is going to fluctuate up and down. I see nothing to worry about. Don't go looking for a problem that isn't there.

Mine says, design capacity 4790mAh, current health at 4754mAh (99.2% of the design capacity). It fluctuates. What you're seeing is normal.

I've had prior MacBooks that went below 80% at 2 years, not within the 1yr warranty and some that held up very well like my current work machine, 1yr old and 97%

My MBP is still hitting new lows. Dropped more down to 91.7%. Now typically 93.9%. Never higher than 95%.

Seeing similar things on my machine. Brand new. I think all the battery hysteria going around is just making the likes of us more paranoid than need be.
