Keep Battery at 80%?

[BigMcGuire]

Is there anyway to keep the battery at 80% and plugged in for battery longevity? I had an IBM Thinkpad awhile back that let me keep the laptop plugged in but at an 80% charge - my old Samsung Ultrabook did this too. Anyway to do this on a Macbook Air 11 (2015)?

My Macbook spends most of its life in clamshell mode plugged in to an external monitor. It looks like you have to keep it plugged in to do clamshell mode.

Is this still the case? Totally cool if so, just thought I'd ask. Edit: If this is still the case, mods feel free to delete.

I don't think there's any way to get the laptop to stop charging at a certain percentage.

I also suspect it doesn't matter. I've owned several MacBooks, I've always kept them plugged in almost all the time, and they've all had excellent battery capacity vs. time.

Also, the percentage indicator on-screen isn't necessarily "accurate." You might really only be charging it to 80 or 90% when it says 100% on-screen, just like there's some charge left when it appears to get down to 0%.

Get Applecare, you can even buy it off other sites such as Amazon at a cheaper price than Apple.

It has come in handy for me on multiple occasions, and once your battery starts going down, Apple will replace it within the 3 year time period. The cost of one battery replacement is equivalent to Applecare, probably even cheaper so I definitely recommend you get it.

OK I think I will do that. I have AppleCare on my iPhone 6+. http://www.amazon.com/AppleCare-Pro...UTF8&qid=1436413381&sr=8-1&keywords=applecare

Thanks for the info!

My 2013 MBA just had its second anniversary. Much of the time it is plugged into the wall and connected to an external monitor, keyboard, mouse, audio interface, etc. Battery life is still excellent, I don't see much difference from when it was new.

I don't worry about battery life or conditioning. I just use the machine the way that suits me. When the battery finally dies, I will just replace it. I don't have AppleCare. Have owned countless Macs going back to 1985 and have rarely purchased AppleCare. The only time I used it was a Powerbook that wouldn't recognize all the additional memory that I installed back around 2005. Apple did two motherboard swaps and it still didn't fix the problem, so I just gave up and lived with the amount of memory I had.

Anyway, I would have wasted enough money to buy several more computers if I purchased Applecare with every Mac. Extended warranties are almost always a bad deal for the customer and a good deal for the company. JMHO
