Hi there,
I recently purchased a MacBook Pro M3 Max 16-inch and plan to use it with an external monitor. To preserve the battery life, should I keep it plugged in all the time, or is there any risk associated with this practice?
MacBook Pro 16″, macOS 15.1
That computer is a battery-CAPABLE device. It is not optimized as a battery-operated device. (It is NOT an iPhone.)
Your computer performs best when connected to AC power, such as the power adapter. It can use the full output of the Power Adapter AND when doing especially challenging work will also freely "borrow" power from the battery. In some cases, even with the power adapter connected, the charged state may decline during very stressful work.
When used only on battery, your computer has no extra cushion of power, and may perform more slowly. However, for ordinary non-stressful tasks this may not be objectionable (possibly not even noticeable.)
In general, you should ALWAYS connect a power source when it is possible to do so, and only run on batteries (which could be somewhat slower) when no power sources are at hand. Your Mac will NEVER over-charge.
Thank you, but is it normal for the number of charging cycles to increase, knowing that it is always connected to the original charger?
if it does increase, it will be very, very slowly.
