What do you think the effect of constant charging will be on battery life in the long term?

There is no practical impact on modern batteries from being constantly connected to power.

  I guess, I confused it with the batteries amount of charges before decline. good to get it confirmed here.

  this is not true, liion dont like being constantly kept at full.

Do you connect your laptop to a monitor without also connecting the charger? My MPB is used in 2 ways: on a desk or lapdesk without any peripherals, or with 3-4 connectors (including hub/monitor and charger).

  I did before, but in that setup I turned the laptop screen off.

Probably not huge - my MBP's battery is 644 days old, and I use it plugged in pretty much all the time. So it's had 34 cycles. But it's still got 92.4% of its capacity left.

  Lord, just 34? I use mine disconnected a lot but mine has over 300 in about a year.

Assuming a properly engineered device, the battery shouldn't actually be constantly charging. It should intelligently switch between power sources, as well as enabling and disabling charging of the battery as needed. I think what is more of a concern would be the possibility that some laptops now tend to unthrottle the CPU when on AC power (or more accurately throttle their already LV CPUs when on battery), which can mean the internal temp gets pretty high and can be bad for the battery. That being said, we have no guarantee that the power management is being done properly, but Apple seems to really have a handle on the power usage of their devices (even if they can't quite figure out their connectors or software). It's definitely a concern on lower end laptops.

  Yes, apple has been quite good with batteries. Indeed part of battery quality is to let the device manage when charging happens, but a big problem is that the device is expected to be charged when being hooked up to a charger for a bit. You don't want customers to walk away from home thinking they have a charged device, but end up only being able to use the device for a short time. I guess there is some well thought out system to it.
