Keeping Macbook Pro Plugged In
Keeping your MacBook Pro plugged in all the time will help to ensure that it always has a full charge. This can be helpful if you’re someone who relies heavily on their laptop. On the downside, keeping your MacBook Pro plugged in can shorten its overall lifespan.
If your chargers light does not come on, then your reason for your MacBook failing to power on or charge may be the defective plug. That is why it is good idea to avoid leaving the MacBooks battery plugged into your charger at all times. If you keep it connected the whole time, your battery cannot get too hot and it cannot harm any of your other components.
If you plug in a third-party charger for the MacBook, you will be able to see either green or orange lights, which means that the battery of your MacBook is charging just fine. Since each battery loses some charge a little bit over the years, you might run into some issues in deciding whether keeping the MacBook connected at all times is contributing in any way. If your MacBook is brand new, there is a chance the battery was faulty to begin with, and does not retain any charge. If the battery is indeed dead, you may want to install the recommended replacement which will fit the laptop.
If your MacBook is one of several models of MacBook, you are eligible for a free battery replacement. If your laptop is not under warranty, you may pay Apples service fee for the battery. You can bring the laptop into an Apple store or authorized service provider, let them inspect the battery (and the rest of the hardware), then get your battery replaced at no charge.
Customer says the battery was replaced at a different computer store, but you still do not get any power from the MacBook. Of course, your MacBook is not going to be charging a battery since no power is coming from a MagSafe charger. If you plug a MacBook into a travel-specific power adapter, the Mac may not charge a battery, even if you shut down your Mac or sleep it. Definitely also do not charge an iPhone or iPad while it is connected to the MacBook.
|Charge Cycles||The charge cycles of your battery degrades when plugged in for long time|
|Temperature||The battery becomes hot so the MacBook gets hot|
|Charging Capacity||Leaving a Mac plugged in and charged to 100% constantly may result in reduced charging capacity|
|Swollen Battery||Leaving a Mac plugged in and charged to can cause a swollen battery in the long term|
If an app is drained of its battery too fast, you might have to suspend the app to allow the Mac to begin charging its own battery. The less power the laptop uses, the less cycles you will run your battery through.
If you charge the laptop overnight and get to work at 8am each morning, the MacBook is going to be waiting for that last 20% percent to recharge. That way, you will have your MacBook fully charged by the morning, so that you can use the MacBook for your entire day. If you choose to keep the laptop around without using it for an extended time, make sure that you keep the charge around 50% of the battery rather than keeping it 100%. There you have it, keeping the MacBook Pro connected to a charger for long periods is perfectly okay because it uses Lithium Polymer batteries that cease charging as soon as your battery hits 100%, which means that when the laptop is at 100%, it is going to run on power from the charger, not your battery.

If you do happen to have damage to the battery, indicated by extreme heat or swelling, leaving the MacBook Pro plugged in overnight is not a great idea. This is what makes charging the MacBook Pro/Air overnight a safer proposition, with no need to worry about overcharging it, or damaging the battery. To prevent that from happening, do not leave the MacBook at 0% charge for a very long period of time. While leaving a laptop connected all the time is not harmful for its health, the excessive heat can certainly harm the battery over time.
Factors such as charging cycles and heat degrade batteries, and leaving a Mac plugged in and charging at 100% all the time could lead to a lower charging capacity or an over-swollen battery over time. Some who have MacBooks have wondered whether or not leaving them connected to power sources all of the time is okay, as opposed to using the included battery on occasion. Leaving anything on a plugged-in battery at all times can make it charge past its capacity, though you would not know it by looking at a battery life indicator alone. Your battery might get a year or two longer if you keep your MacBook connected to a charger more often, in order to keep your battery use down.
If you are going to store the computer for several months, you will want to recharge to 50% of its charge every 6 months or so, so that you do not lose any battery capacity. Before trying more complicated solutions, recharge the MacBook with an adapter at 100 percent, then use it for two hours while you have the charger connected. If you are seriously concerned with increasing battery life, you should keep the battery charged between 80-30%, never dropping below 20%, charging the laptops to 100% is not ideal for battery life either, though leaving the charger connected if its already at 100% does no harm as it will run off of power from the charger if plugged in. Remove the charger at least 3 times per week and allow it to run on the battery, though while running on the battery you should make sure that the laptop does not fall below 20%, dropping it consistently under 20% and charging it up to 100% will slowly but surely reduce battery life.

It is important to know that the battery life of your laptop will naturally decrease overtime, there are some things that can be done to maximise the battery life, but over time, it will depreciate naturally, and leaving it to 100% sometimes is not an issue, but using your battery every now and then is ideal. You can minimize cycles by keeping the MacBook connected, letting the battery management tech do its job.
Declined means the amount of juice, or the amount of time, that your battery can provide your MacBook before it gets to empty and needs recharging, may have been reduced compared with what was possible when the components were new. If your MacBook is not charging anymore, your battery may have been damaged beyond repair.
Is it better to put my Mac to sleep or shutdown?
As a general rule, letting your Mac sleep is generally the best option if you’re only going to be away from it for an hour or two, or even overnight. For the reasons listed in the following section, if you leave it on for any longer than that, you should turn it off.
Why is my MacBook Pro battery draining so fast?
Thanks to macOS, your MacBook recognizes whenever it is connected and behaves appropriately. For instance, it utilizes conservatively other parts and dims the display while utilizing battery power (should such a feature be selected). Your battery will discharge rapidly if you adjust this option to optimize efficiency.
Does your MacBook know when it’s Plugged In?
Thanks to the mac operating system, your MacBook recognizes whenever it is connected and behaves appropriately. For instance, it utilizes sparsely additional parts and dims the display while utilizing battery power (should such an option be selected).
