How long did it take for a MacBook Pro 2012 to charge from 0 percent?

Answer 1

The length of time required to charge a MAcBook Pro is dependent upon how much charge was in the battery before recharging started and if the computer is being used while the charging takes place. From flat to fully charged while being used can take four or five hours but will be around half that long if it is not being used.

Answer 2

The battery in a new MacBook will normally be around 40% charged so it can used right away. Charging from the mains will take between 1 and 2 hours. It will stop charging once the battery is fully charged so can be left overnight for example. (See links below)

Answer 3

You should try to let the battery run low to prevent battery memory. But really, you can charge it whenever you feel you need to. In the top right corner, click the battery icon, and click 'show percentage'. This will tell you exactly how much battery power your macbook has left.

Answer 4

Contrary to popular belief, you can keep it connected to a charger for long periods of time, even if you're fully charged. The MacBook hardware is designed to where it won't overcharge. Doing it this way will keep your charging cycles low. If you keep it on the charger, make a habit of unplugging it and run on battery from time to time. When you're running on battery, good rule of thumb is to recharge when you're at the midpoint range of your charge cycle (50% or so). If you happen to let it go down further, it's recommended to recharge it again when you drop down to approximately 15-20%. It will hurt your battery life in the long term if you let it drain near or all the way down. In addition, it's not a good idea to be plugged in and on or sleep mode while you're away for several hours. You should instead turn it off, but can remain on the charger. Leaving it on/sleep mode when not in use increases the chance of parasitic loading, which in turn will negatively affect your battery's charging cycles.

Answer 5

In reality it takes about 3.5 hours from 5%

Answer 6

Charge it whenever it starts getting low! It depends on how much you use it.

Answer 7

2 hours
