Battery Performance

Battery Life, Battery Saving, Charging Time

Battery Life (Time between two Charges)

Very individual, difficult to compare. Dependent on use.

Little use: possibly x days (check mail inbox daily, visit one or the other website). Not tested, as the following applies better to me:
Heavy use: x h (emails, 5 h listening to music, reading a book [Apple books], maintaining this website, web research and editing photos for new reviews).

Battery Saving on my Part yes, but …

In order to protect the battery, which cannot be changed by the user, I rarely push it to its limits, as this wears it out unnecessarily.
When there is about 30% remaining charge, I try not to charge it to 100%.

Battery Saving on Apple's Part …

Unfortunately, even with stationary use, the battery charge does not end at max. 60%, but at 100%, thus promoting premature ageing.

Does Sony have exclusive Rights (Patent) to Battery Saving?

The battery charge is not adjustable for stationary use as I know it from my Sony VAIO Z12X9E/X notebook - for frequent stationary use on the power adapter, Sony recommends the charge setting that always keeps the battery in the 50% range, which protects the battery cells as best as possible. This is how I used this old notebook for years.

Charging Time

Charging on 30W power adapter: 1 h
(at 30% remaining charge up to 70%)

Portable High End Equipment for Audiophiles

03.06.2021: Listen to my favourite album The Best Of The Art Of Noise (1992), 2. title: Yebo (Mbaqanga Mix).
Ideal for testing the low bass reproduction!
Further play tip: 7th track: Legacy.

This is synthesiser sound, which - taken alone - is not objectively suitable for testing the sound quality of a music player. Electronic music sounds good on any device. But I know this album inside out and have already listened to it very often from CD and also on various MP3 players (constant quality encoding; dynamic data rate up to max. 320 kbit/s).

For the objective test of sound quality, I used music tracks with acoustic instruments and very often heard musicians' voices.
The listening test CD “Stakkato” from the hi-fi magazine Audio was also very helpful in the objective test of acoustics (old, but tried and tested).

Linear smooth Frequency Response

The Apple MacBook Air can thus show (at the headphone jack/via Bluetooth) that it has a ruler-like frequency response down to the low bass range. Otherwise, the bass would not be so abysmally deep, undistorted and clear (unfortunately, I cannot measure it).

The signal-to-noise ratio is also excellent. By the way: because Apple devices have extremely low latency, they are very popular with musicians and DJs.

My audio test equipment: As headphones I use the Sony MDR-EX90LP.
These studio monitor quality in-ear headphones offer quite pristine reproduction.

Change from Windows to macOS

It's a huge switch from Windows 7 Pro to macOS Catalina 10.15.x!

IT Professionals feel like Beginners again

Soon you are playing out in your mind the reversal of the purchase …
But just don't think it through! It's worth staying on the ball, er apple.
So far, you have accepted every challenge and not chickened out!
Onward into the depths of space, er apple universe … Wink Smiley

And if you're not an IT professional at all, you'll manage even better!
Because this way you are not pre-loaded with ingrained PC habits. smiley
I found the answer to almost all questions within seconds on the internet. And for the rest, after a few minutes.

If you still can't find a solution to some problems after an hour, don't give up!
I am not the benchmark! Patience, imagination and many years of internet experience make any online research easy for me.
If you are a computer novice, perhaps of an older vintage, and prefer the tome of books, download the free MacBook Air book from "Apple Books" and read it on screen – or buy it in paperback from a bookshop.

A reference book is always good and best in the form in which you prefer to work with it yourself.

Migration Problems

Key labelling: Special characters are missing – you have to laboriously read them from an app that is accessible via the menu bar (upper edge of the screen).

Excellently processed Hardware

Audiophile Features

The audio quality is excellent! The frequency response is from 18 Hz to 19 kHz, as if drawn with a ruler - and the headphone output is hardly any different!

Flat Aluminium Housing

The excellently crafted case feels very good and is a pleasure to hold.

The high-resolution 13.3-inch Display sharply displays Photos and Text

I like to watch my TV series on this screen.

10th Generation Intel i5 Processor, but powerful is different

The MacBook Air is really not designed for work that relies on high processing power!
Even complex websites can make the 10th generation Intel Y processor sweat.
Prolonged file copy actions with the Finder cause the fan to rotate …

Touch ID – Unlocking becomes convenient

The password only needs to be entered after switching on and booting up your MacBook. The corresponding fingerprint is sufficient to unlock the screen.

Poor Performance, but not a Problem for me: the Camera

Since I don't like video chats, the miserable webcam is perfectly adequate for me. It never gets used anyway.

Sleeve or Bag

You want to protect an expensive MacBook from damage.
I had ordered the original leather case from Apple.

Unfortunately, I hadn't checked out fitBAG's online shop for their range of notebook bags. Otherwise, I would have ordered a leather bag there, as I already do for smartphones. That would have been cheaper, because bags from fitBAG are not expensive, despite being made to measure!


  • Absolutely flawless build quality
  • 100% recycled aluminium without compromising on stability or finish
  • very efficient coordination of software and hardware
  • Hard disk encryption efficiently implemented and easy to use (key ring)

  • Reliability and stability of the operating system - no crashes or unwanted reboots since initial operation
  • Memory with secure hardware encryption
  • Touch ID quickly unlocks MacBook, can also be used for App Store purchases (only if desired)
  • good keyboard with good pressure point
  • Keyboard settings such as shortcuts and intelligent word suggestion algorithm are synchronised with the iPhone
  • Display with excellent performance in resolution, brightness and colour fidelity - but not the whole P3 colour space
  • available with 16 GB RAM, highly recommended
  • Safari web browser with very fast page loading and excellent developer menu (including simulation of various screen sizes)
  • ideal for test report writers like me: good screenshot function implemented directly in macOS!
  • no bloatware ex works


  • everything is soldered, nothing can be expanded
  • models with storage sizes suitable for everyday use and future-proof are extremely expensive (1 TB is a must because of the lack of expandability!)
  • no exchangeable battery – battery cannot be exchanged by the customer without tinkering and loss of warranty

Nice to look at, but not to work with

The MacBook Air is really not designed for hard work!
Even opening several demanding websites makes the 10th generation Intel Y processor sweat.
When cleaning up your data collection on SSD or moving many hard disk files, the built-in fan soon becomes audible.
Some users have burnt up the i7 processor including the circuit board in the MacBook because the cooling system is not designed for it!


Model with i5 processor – on the one hand I only do simple things with it, on the other hand an i5 doesn't die of heat as quickly as an i7.


MacBook Pro

The MacBook Pro (2020, Intel CPU) in the smallest configuration is barely more expensive than a MacBook Air (2020, Intel CPU) in a medium configuration!
The advantages of the MacBook Pro: the screen displays the full P3 colour space, the processor is connected to two coolers via heat pipes and the speakers are even better.

MacBook Air M1

Apple's new M1 chip (“Apple Silicon”) is much more powerful.

Apple's iPhone processor is now significantly more powerful than the mobile processors used in notebooks. All Apple's engineers had to do was add more cores, a better graphics CPU, neural processing units and more memory, and other notebook manufacturers no longer play a role in terms of performance …

More powerful than an old MacBook Pro and barely slower than the new MacBook Pro M1 for demanding image editing, rendering and video editing.

MacBook Air M2

Apple's successor model offers even more performance.
Sophisticated computer users like me therefore do not buy the still available model with M1 chip, but the successor.

Price Tip: MacBook Air M1 with 8 GB RAM

In a long, detailed YouTube video, I saw the entry-level model being compared to a full-featured MacBook Air M1, and the YouTuber himself was very pleasantly surprised that the entry-level model was very easy to work with and didn't get hot or slow at all without active cooling!
I would, however, prefer to buy it with 16GB of RAM just to be on the safe side.
