I just tried this, now mine's 6 weeks / 25 cycles / 4999 mAh
i just shake the rMB hard
Keep us informed over the weeks of the mAh drops again through repeated charging.My new MacBook’s battery was just replaced. Now the reading is: 1 week/2 cycles/5310 mAh
Has anyone got over 100-150 cycles and over 97% health? Cause all these stats are worrying me.
3 months/ 74/ 4845
my original max was 5295
I was on a mountain trip and didn't use the rMB for 2 weeks. Before I left my health (well, my rMB's) was 89%.
When I got back it had gone up to 95% and now after 1 week I'm down at 91% again.
Have to say that my mains supply comes from a small wind generator + inverter which is not very stable. That might be an explanation.
Have you considered a voltage regulator, it will help to stabilise the power supply, I have used the same in some areas where the mains power is very erratic.
Q-6
Thanks for the tip. I might look in to that.
Not sure if the inverter has influenced my battery health. I see some others in this thread with have quite similar results with regular mains.
Depends where your based, I found the voltage regulators to be fairly cheap and still have a couple kicking about that I still use as mine also provide excellent surge protection on top of voltage regulation. My regulators hold the output voltage at a nominal 230V across a range of 165V - 280V beyond that it will trip out to protect the equipment plugged in.
I don't think the inverter will influence the battery and it should have an element of regulation built in, equally I would look at a Voltage regulator if I was on the same type of power supply, as stabilising the voltage will increase the longevity of all appliances on the local grid.

When we lived in locations where the power supply was "dirty" I have little doubt the regulators more than paid for themselves.

Yes, it`s better to use portable Mac`s off the mains supply from time to time, as it helps to keep the battery "healthy" run the rMB off the mains supply until the battery percentage reads around 80% and recharge, once or twice a month is enough.
Q-6
While I agree that keeping battery cycles low should naturally lead to better battery preservation, I wonder - is this really the case in the real world?
I have a 2009 MacBook (the last white model, before the white unibody arrived). It was used (on battery) daily in high-school, and recharged pretty much daily. It is now used by my mother. It has nearly 700 cycles on the battery, and it's still showing 96 % battery health. It still returns nearly the same battery life as it did when new. Absolutely amazing if you ask me.
My MacBook Pro Retina from 2014 has 195 cycles. After having used it on power for a longer period of time, without depleting the battery, iStat showed a 91 % battery health. Weird, I thought. Now I charge it fully, and deplete it fully, over and over again, and the battery health is at 95 %.
I for one think batteries need to be used to work properly. Sure, after 800-1000 cycles your battery will obviously have degraded, but by then you're probably thinking of a new laptop anyway. Oh and lets not forget. These are portable computers after all. Buying the smallest and most portable MacBook and not using it on battery is a bit silly if you ask me. Use it as intended and stop worrying!
Wow, the battery needs to be addressed for sure in the next product release (along with the mystery rattle).Just checked my battery and it dropped down to 88%. 54 cycles, 4676/5297 mAh.
