Great battery life has been the biggest story of Apple’s M1 laptops up until this point, with many people describing the Air and 13-inch MacBook Pro’s battery life as “all day.”
If you charge your MacBook at less than 30%, the system will be harmed, and the battery will be harmed. Do MacBook Pros have good battery life? The 13-inch MacBook Pro (2020) edition has an inbuilt 58.2-watt-hour lithium-polymer battery that provides up to 17 hours of wireless surfing and up to 20 hours of Apple TV app movie playing between
The only laptops we’ve tested with a longer battery life than the MacBook Air M2 are the MacBook Pro 13 M2 (19 hours and two minutes) and the MacBook Pro 16 M1 Max (22 hours and 30 minutes). Even though the MacBook Air and MacBook Pro 13 both have the same processor, the MacBook Air has a slightly smaller battery capacity than the MacBook Pro

My Air has currently 4 charge cycles and battery health fluctuates around 4325-4340mAh (it should be 4381mAh or over), so battery health is 99% and under at the best. While that might looks good for many, I beg to differ. From what Apple tells us these batteries are supposed to last 1000 charge cycles.

Mac laptops may be eligible for an extended battery-only repair period for up to 10 years from when the product was last distributed for sale, subject to parts availability. Find out which products are obsolete: The batteries in MacBooks are supposed to be good for 1000 cycles. If you battery dies after 600 cycles you probably have a case with Apple to get a replacement. Having said that, the same chemical process that made your capacity go down by 2% in one week is likely to also likely to have other disproportionate changes. The new MacBook Air 2020 offers about everything you might desire in an Apple notebook, due to its M1 Chipset, which enables record-breaking performance and battery life. The MacBook Air, when brand new, can last for an incredible 29 hours in ideal conditions, but if the question is, how long does a MacBook Air battery last before battery life 2 Months old MacBook Pro (Mid 2020) battery only last for 4 hours. I'm new to the world of Apple, I bought a new Macbook Pro, mid-2020, Intel i7, 16GB RAM. I'm a developer, I run apps like VS Code, Sublime Text, Slack, Chrome (Multiple Windows), I play videos/songs in the background. I have been keeping a track of the energy consumption on my
If you purchased an AppleCare Protection Plan If you don't have coverage, you can have the battery replaced for a fee. MacBook, MacBook Air and MacBook Pro computers with built-in batteries should only have their batteries replaced by an Apple Authorised Service Provider or Apple Store, or by an Independent Repair Provider that uses genuine

That on its own made it comfortably the best in its class, but thanks to an increased battery capacity (up from 50-watt-hour to 54-watt-hour) and the energy saving tweaks introduced in OS X 10.9.3

The MacBook Air M2 starts at $1,099, which is $100 more than the MacBook Air M1. The starting configuration gives you an 8-core CPU, 10-Core GPU, 8GB of unified memory and 512GB of storage.
That actually translates to about 12-13 hours battery life for the 2018 and 2019 MacBook Air models, 10 hours for the 13in MacBook Pro (2018/2019), 10 hours for the 15in MacBook Pro (2018/2019

MacBook: "Your battery is designed to retain up to 80% of its original capacity at 1000 complete charge cycles. The one-year warranty includes replacement coverage for a defective battery. Apple offers a battery replacement service for all MacBook, MacBook Air, and MacBook Pro notebooks with built-in batteries." The MacBook took 12'13", and the battery dropped from 81% to 74%, so 7 percentage points. At the same rate a fully charged battery would have lasted 2 hours and 53 minutes - which is in line with OP's findings, as AE/AME doesn't seem to push al the cores to the max (it's a long standing AE complaint, there doesn't seem to be a good way of using
Open Activity Monitor from Spotlight by hitting Command+Spacebar then typing ‘Activity Monitor’ and hitting return. Pull down the “View” menu and go to “Columns” and check the “Preventing Sleep” column on. Now you can sort by “Preventing Sleep” to see what, if any, processes or apps are preventing the Mac from sleeping.

Hold down the Shift, Control, Option, and Power keys. Turn on the Mac. Look at the battery status menu to see if the Service Battery Warning message is still there. 2. Recalibrate the Battery. A service battery warning on a MacBook can be a real bummer, but the good news is you can fix the issue.

1) Letting the battery run down is not necessarily good for it. It's arguably bad for it. 2) Of course you can leave it on AC power when it's fully charged. The battery will stop charging when it's full, or nearly full, so there's no difference between leaving it plugged in and unplugging it.
Avoid high temperatures by keeping air flow around the MacBook - for example, don't rest it for long on soft bed covers. Apple don't say, but battery is probably happiest between 40% and 80%. Edit: Apple are very reticent about precise advice regarding battery health. Well, you need to have an extra care to your batteries. It is true that it can last 5 years since it is designed with a lifespan of up to 5 years but, extra care is also needed. Do not leave your Macbook plugged in all the time, because it was designed to be plugged and unplugged to allow the battery to discharge and recharge on a normal cycle xncLZ.
