Gary Sims did a battery test a while back, and high screen brightness together with a heavy load on I/O or the performance cores seems to drastically reduce battery life. I guess the battery life could range from 2 hours to 20 depending on the circumstances. A bit annoying since I think a lot of people would like a fixed number, like "I know I have 8 hours".
@@MarkEllisReviews Yep. Screens *are* the #1 battery drain on _any_ laptop in consumer workloads. From AnandTech's testing, though you may not like benchmarks or any of that, it's useful to know: "Displays are easily the biggest power draw in a laptop. A 15-inch Surface Book 2 draws 7.65 W of power just to drive the display at 100% brightness. The rest of the system only draws 1.43 Watts. On that laptop, the display consumes 5.34 times more power than every other component combined." At 100% brightness, the display consumes 84% of total power on the Surface Book 2, which has a similar high-resolution, high-gamut screen.

@@MarkEllisReviews In fact, the M1 MacBook Air's screen brightness impact on battery life has been tested and your data perfectly aligns with Notebookcheck. The battery itself is not an issue; it's the screen brightness: M1 MacBook Air at 100% brightness = 8h 28m M1 MacBook at 150 nits brightness = 16h 00m You can double your battery life, if you move from 100% brightness to 150 nits (I'm not sure how many ticks that is, unfortunately).

@@ikjadoon That is indeed a lot! The new screens that are rumoured to be in the new MBPs are supposedly drawing around 20% less power. Considering they are also rumoured to have twice as many power cores they could potentially last shorter during full load and longer during "average" use compared to todays M1 MBP.
Any typical windows machine will run out of battery in 3-5 hours with maximal screen brightness. I‘m actually stunned by the fact you pretty much manage to get a full day of battery at maximal brightness.
@@aditjindal $800 4 years ago... MacBooks had dual cores at that time... you just proved my point, it's not exactly a shocker a $800 laptop from 4 years ago preforms worse than a $1000 laptop of today
As far as remember I have seen a test on RU-vid where the tester more or less left the computer doing nothing, but with the screen at full brightness. It lasted about 8 hours. So I think the problem definitely is the full brightness.
Great video, thanks! Hahah I really watched all your vids about MacBooks! Waiting for my M1 Air cuz I’m quite impressed now. It works great! No more 3-4 hours and then sitting near the sockets
I don't think your battery is defective. The screen brightness setting has a huge effect on battery life. If you reduce the brightness when you don't need it, it is possible to stretch the battery life for longer, I believe. Thanks for the video.
@@MarkEllisReviews I'm using my m1 air similar to you. Web browsing, RU-vid, Skype things like that. Brightness set to 50%, low energy usage on, even optimization of video on and I still cannot go above 8h of work. My main reason to buy this MacBook was that every one on reviews said how amazing the battery is and that 14 hour of working unplugged is something completely normal too this laptop. So imagine my disappointment when I started to use it.
My M1 MacBook Pro easily gives me 18-20ish hours when doing productivity stuff @40% to 50% brightness. It’s more expensive but the capability to be away from the wall socket for longer is worth it!
have you tested with the new "Low power mode" in MacOS Monterey? Supposedly should be limiting the overall clock speed from 3.2 Ghz to 1.95 Ghz. Considering low power mode in in iOS actually disables the high-performance cores, we may have the same method in here. What do you think? :)
Stop using max or close to max brightness indoors. In numerous comments Mark has stated that after more testing, not using max or near max brightness dramatically increases battery life
Same here, but I’m on a pro. I do all my marking and paperwork, have a few tabs up and running. I also use flipgrid and edmodo for listening and oral presentation uploads with my students ( I got a message that edmodo is pulling a lot of energy, never saw that before) and go to bed around 2am/ 3am and end with about 30% battery. I don’t think I ever charged my mbp past 80% so I think it does really well. That 30% can take me through all my Teams meetings (3 or 4 hours) before dying and I can probably still get to do an assignment or after my classes. The battery life for me is insane. I love that even with less then 30% I don’t have to worry about it dying on me.
@@trini_ice_queen I do video presentations in a Blended Classroom where I guide the students to a learning objective. And I'm looking at the Air, I appreciate your comment (We are all unique in our workflow) as it appears as close to what my application would be. Your comment certainly helped me come to decision to buy. Thanks
@@dcmsr5141 No problem. Yesterday I was on a 6h 30 minute Teams conference call with a colleague. I know I started with roughly 60%. We are on the ICT and Curriculum committees so we did a lot of screen sharing and document work during that call. Didn’t even realise I spent so long on that call. When I ended the call with her I was on 16%. I didn’t plug in once. I also had to screen record a video for a group I am a part of. That screen recording was 30mins long. I did it twice cause the first time I forgot to turn off my notifications. After those two recordings I had 10%. The battery life on the MBP is really excellent. I can’t speak personally for the MBA but I am certain you can get through an entire day without worrying about charging on the MBA M1 chip as well.
I haven't properly documented the battery and time, but when it comes to "everyday" usage such as browsing with an unseemly amount of tabs, RU-vid, some programming, messaging etc it just seems to go on and on forever. I can't say for sure, but it HAS to be way more than 8 hours. However, when I play World of Warcraft it will go through the battery much, much faster (no surprise). Maybe 4-6x faster or even more? Like I said, I haven't properly looked into it so I'm just guessing. LTT did a battery test recently and they found that the MBP M1 did significantly better when it comes to the battery. It shouldn't though as the battery is just slightly larger.
Interesting - thanks for your input. I think the screen brightness may have been to blame during my test, but I'm going to look into it a little further...
Totally agree with you, this is strange, my workday consists of around 5 hours of mid to heavy work and I am consistently getting 12 hours plus of screen time, meaning I don't need to charge for 3 days, amazing. I think with this battery the Apple just changed the game, getting 5 hours plus on a battery meant a lot of compromises with other laptops, but with M1 it just happens, like Magic :-)
@@MarkEllisReviews I'm using Macbook Air M1. One thing, that I mostly use my laptop with around 50% screen brightness and in sessions of like 2 or 3 hours, maybe that's why I am able to get 10+ hours.
@@Majidfazal01 I don't think I could do 50% on my Air. I keep mine 3 dots from max - whatever that is, 80%? I feel like I get great battery life, but no doubt you will get significantly more with the screen brightness set to 50%.
@@mplovecraft Yes, you are right, I've always been a bit more comfortable with 50% brightness, easier for the eyes and now good for the battery timing too :-)
Great video, Mark. Recently subscribed to your channel and I'm really enjoying your content! Keep up the good work. I've just purchased the M1 MacBook Pro and I'm going to conduct a similar experiment shortly - fingers crossed it'll last me for the day!
I have the m1 pro and usually at 25% or 50% brightness at max. Don’t really have any major background apps running nonstop, etc and can easily top 20+ hours of use. I do always keep Bluetooth off too. Random question, what is your method for cleaning the screens on these laptops?
You're right - the screen brightness makes a massive difference - as I've found out! As for cleaning screens, I always buy the cheapest microfibre cloths available on Amazon and use them for all screens - they're amazing. This kinda thing: amzn.to/3qg39wc
Same here. Low screen brightness and no Bluetooth as I use the trackpad. I’m surprised your office are so bright. I prefer to work in a darker environment and therefore the screen brightness is only at as out 25%…
Decrease that brightness mate, I believe it’s the reason your battery drains so quick. You don’t need a blinding 100% when working indoors, half is probably enough and better for your eyes also.
Trying that test as we speak. Although it's worth noting that the screen was actually set to auto brightness and it never felt particularly blinding or that I was pushing it... Still, let's see what this new day brings!
For some reason couldn’t sleep last night so RU-vid became my night watcher. I stumble upon your channel and watched about 25 videos, all of them got a like from me (and I am usually picky) just because you found a way to seem like a regular “joe”, identifying with your viewers, even though you are not (music/video production, bit of a photographer and so on) plus I love to watch small channels grow (especially if I am right about their quality :) I will keep watching your channel, see you again @1 mill subscribers! Just patience...Apple is still considered a “niche” company and the users Isheeps (I don’t know if you heard of Tailosive tech or Everyday Dad but they are slowly growing for years just because they cover only Apple). Myself I’ve been using Apple products since IPhone 3G
Wow, genuinely don't know what to say to that, thank you for your kind words. I'm just loving creating this content and building such a great community. I love the passion, whether it's for or against Apple! And I really hope you managed to get to sleep after that marathon!
Your problem might be the brightness of the screen. My experience with my iPad is that it runs out way faster when I inadvertently had the brightness turned way up. When I use my MacBook Air M1 the brightness is normally around half brightness and you have to remember that is around the brightness Apple uses in their battery test. This will however be a mute point if half brightness is to dim in your environment and you did say you wanted to use it without doing anything out of the ordinary to preserve battery life.
Great video and good test, im still watching videos of the new Mac m1. Im a Windows user always wanted to buy a Mac. And finally the price is right. I edit in Davinci Resolve and I see they have a beta version. Im thinking of buying the Mac mini, do you think it can handle 4K footage with effects in fusion. You got a new subscriber from Norway🇧🇻. And I join the discord. Have a wonderful day.
Thanks so much! And I can see you've joined the Discord server 👍 Stay tuned to the channel - I've got lots of M1 Mac mini stuff on the way. But initial tests suggest it is a superb video editing machine. I do use Final Cut Pro, though - so can't talk for DaVinci...
I think its the brightness. If you lower it a bit (I usually go for 20% brightness on battery), it'll last twice. Also, I think you need to put your macbook air on laptop cooler from external source so that processor wont throttle. However, no windows laptop could last that long if you do video editing.
Thanks for the battery test - very interesting. Love the content = subscribed! Would you mind sharing how you edit your video app/plugins and how you create the pulsing logo etc, they are amazing 👍🏻
...do you need max screen brightness when using a laptop indoors? I barely ever feel the need to go beyond 2 bars above the middle point and LCDs consume considerably less power at around half brightness (it diminishes at less than that, tho, you don't save as much going from 60% to 20% as you would going from 95-100% to 55%). Going from 95% on my T470p to around 60% made it go from around 2h battery life to just over 4h. at 20% brightness it barely gets to 5 hours.
I used my M1 for around 3 days without charging, but only probably 5 hours a day. BUT I had my keyboard brightness down pretty low, screen brightness at 4 or 5 from the bottom (bright screens hurt my eyes) and I only used Notion, Apple Notes, News, a Bible app, and safari for research. It could be the big mix of apps you are using and the higher workload (editing, video conferencing). I think I am a typical MacBook Air user (college work and the things I mentioned with occasional video conference). My opinion: I doubt it's your battery, I think you just have a high workload for this little computer.
@@MarkEllisReviews Yeah, on re-evaluating I'd say I'm using the comp lightly for 3-4 hours a day and charging on the third day (maybe 12 hours *light usage or so). So Apple may be overstating their battery endurance a bit for sure.
Do you think using the 60W MacBook Pro charger will damage the battery health for MBA? btw great content and thumbs up to the Jeremy Clarkson reference haha!
I’m not beat qualified to give you advice on that, but I don’t think it would cause any issues. And thanks for the kind words - glad you liked the Clarkson reference!
Just got mine M1 MBA, some light setting up, messing around a bit learning as this is my first Macbook. Will maximum get 6 hours on 2/3 brightness. And that is very disappointing. Love your work, great videos.
@@blackchartsforex3124 6 hours consisting of 2 hours watching Apple TV movie, other 4 hours just light playing around, very light, no heavy applications at all so yes, I think this is very disappointing.
Great video! Getting my MacBook Air today and I was just wondering do you need WiFi when first setting up the Mac or can it be by using internet from your phone hotspot, WiFi is down so currently I just tether my internet from my phone and wondering if that will work ?
Thank you! I'll need to leave the answer to that to someone else, as I've only ever done it via WiFi. But if you have hotspot turned on on your iPhone, in theory, it should work. Give it a go!
I got a brand new M1 and I'm in Canada and I found it didn't hit close to the time they say it would for using the battery. I think your usage was more realistic to me and I just got a new one. so I think they were over hyping the time of the battery.
My results have been almost exactly the same if not slightly worse. Kind of reassuring actually! I'm not sure how hard other users are pushing their machines, but my work involves using VM's and more. It also seems like leaving the Calendar and Mail apps open takes a significant hit, which is kind of a shame given how useful it is to always keep them open.
I just got m1 MacBook Air and so far not bad at all: still setting it up and not really working on something at the moment. Seems to be fast as I was not loosing any frames on some video work I did in thei past.
oh, man, I'm forced to use Teams for work calls and chats. Over 14 months and they still haven't provided an M1 version. I did order my Macbook Air a few days ago, gotta arrive here in 4-7 weeks (custom order, long delivery time) but we'll see how it performs.
I just came across your video today, as i was running battery test on my mac. I also thought that my mac might be a faulty one. But i guess under particular circumstance they might get closer to the claimed battery life
In my opinion reducing the brightness to around 70% would give you extra 2-3 hours. Still not as advertised, but at least it would last your typical work day. Btw love your channel! 👍🏼
Thanks Patrik! I think the screen may have been a big culprit, with hindsight. But I’ve since discovered that it was on auto brightness, so it will have modulated a bit throughout the day (although likely remained at full for a large portion of it)
I would also consider installing the Big Sur 11.2 beta to see if that made a difference along with brightness tips. The other one I'm umming on is how efficient Google Drive is.
Are there specific fixes in that beta for battery, then? Also, I should probably clarify that I was only using the G Drive website, as opposed to the desktop app (which I can't stand).
@@MarkEllisReviews Thanks for the speedy reply! Look I'm making a very large assumption. I don't think apple has specifically mentioned battery but they rarely do - taking iOS as an example, other versions performed more efficiently than others. I can only speak for my i5 MBP, 11.2 is so much smoother so it's worth a try. I'm getting my M1 MBA at the end of this month otherwise I would try myself as I'd rather have the fixes sooner before public release. Can't hurt!
My M1 MacBook Air only lasted 6 hours with only 3 hours of video watching and light file transferring, screen brightness was 50%. ☹️ I’m running Big Sur 11.6.2
Are you’re USB C ports quite tight? Received mine a couple days ago and I find they are a bit too tight as some accessories are hard to remove with one hand.. For example, I need to close the lid and hold the laptop with one hand to pull out the charging cable. What’s you’re experience?
Not that I've noticed, no - seems to be tight enough to be secure but not so tight that I have to yank it out. However, I often find that some USB C connections are tighter than others; it seems to be the cable rather than the Mac.
exactly the same issue I am having I was actually search on RU-vid for answers and stumbled on your video mine is a MacBook Pro M1 I have heard people talking about 20 hours use and I haven't experienced such .. I decided to turn on the low power mode to see if that gives me that same number but I still have doubts too
Hi Mark, Fascinating video and for me it's nice to see a reflection of a typical work day which I can relate to, and it's nice to see reality vs the hype - Whoever decided that they would use number of hours watching youTube as an indicator of battery life was a marketing genius, as that is the only headline that you can remember. It would be great if you did a similar video for the new M1 Pro and M1 Max models - If you ever get to see this comment.
I also recently bought an M1 Air and was disappointed with the battery life. For me, switching to Chrome (vs Safari) made a bit of a difference but I like to have LOTS of tabs open. I do prefer Apple software on Apple hardware and have never really tried Chrome before but it's helped some with battery. *shrug* I wonder if people just "guestemate" battery life based on the first few hours, even your test had you down only 8% in the first 2 hours. I enjoy the videos. Let us know if you decide it's a faulty battery.
Thanks for tuning in! I don't think my battery's faulty, after further tests. It was a combination of the screen brightness (main factor) and Teams, I think. Just with the brightness lowered (still perfectly workable), it's giving me loads more battery life. The standby time is still one of the unsung heroes of this laptop, though - I just hardly ever have to worry about charging it while not in use.
If uve got problem with battery of m1 macs u gotta some psychological problem and probably most other laptops too since there’s no laptop that even come close to m1 macs to battery life
@@simply6162 Probably not a 'psychological problem', dude. It's a worthy test, given how much hype has surrounded the battery performance (and to which I've admittedly contributed).
I have a 4 days years old macbook air m1 and the battery is not as great as I thought, I use full brightness, do some office work, only using safari and pages, and it seems like it only lasts 6-7 hours, nothing in the background Is it still indexing? Or it doesn’t matter? I dont know wether I should take it to apple, I thought its gonna last 2 days Everyone said they forgot about the charger with this m1 macbook air
To be fair, I'm not a power user and don't use any of the apps you mentioned in this video. That being said, my results are still surprising. I watch quite a bit of RU-vid, AppleTV, and other uses that I think are battery hogs and I rarely have the screen brightness above 50%. I can go for more then 2 days without charging and I think that's amazing from a laptop. Any laptop. Great battery review btw.
Can see the British January overcast sky in the background... God knows why you have it on full brightness! It's pretty unnecessary. Try bringing it down just one notch and seeing how that is. And progressively keep doing that and you'll find a level that's comfortable but not so bright.
😂 hey, what are you saying about our weather? 😉 It was the screen brightness - lowered and battery life has been great. Interestingly, though, it never felt overly bright that day. And, incidentally, it was actually auto brightness, not 100%.
@@QuattroRMT A great solution. But some people do just want a Mac (or perhaps prefer macOS - I know I do), and if they've got the budget for it, why not? 😊
I think you had lot going on with multiple apps opened and doing multitasking. I guess some apps aren't optimized for arm-based chip since it's new to the laptop market.
I'm not great with tabs, but I'm also not the sort of person who leaves _loads_ open (not that there's anything wrong with that). In my experience, Safari is only ever a battery hog if the website or app you're accessing is poorly optimised. But even that happens pretty rarely.
@@MarkEllisReviews when i was filling out my fasfa, i noticed it was draining superrr fast and that website always acts up so maybe it isn’t optimized?
It's the brightness, I have it on the default 50% it ships with (along with true tone, so environment and the weather is a variable I can't compare with your setting), but at 9 AM I started it up, did some work, then watched 2 episodes of Arrowverse on Netflix (that is about 85 minutes of HD video streaming), then I looked at the battery and it was still 100%, I was like "WTF" so I looked it up and found your blog and video.. The biggest thing I saw you mention was the brightness, I know on iPhone (or any other phone), having the brightness on 100% is an extreme battery drain in comparison with other settings, frankly I don't even understand why you'd want to have brightness on 100% unless you're outside and the sun is shining, anyway.. now I have 98% of battery and it's 12:25. And your drain was what, like 13% per hour? That's still amazing in comparison with any other notebook out there.
@@MarkEllisReviews So got mine and tried it with external monitor. Within three hours, lost around 45%. However, the screen on time without an external is good averaging with a battery consumption of 35% for 6 hours (Roughly) .
@@MarkEllisReviews Thanks. Seems mine is bad battery. On low brightness(below 50%) It doesn't reach the 12hrs.

Battery health still at 100% though. Is there some kind of update or something I can turn off?
I’ve since discovered that it’s actually on auto brightness, so it’ll have been modulating it throughout the day. Again, that represents standard use for me, though.
hello great video! I wanted to ask you about the MacBook Air m1 battery performance, starting from 100% and with basic use (web, RU-vid, social networks, pages and mail) what percentage of battery should I have after one hour? Is it normal to lose about 10%? Thanks for the reply
I got like 10-11 hrs of battery with zoom, watching RU-vid videos, browsing on safari, WhatsApp with 50% battery. The battery life is 97%, is my unit defective? please reply
It is possible that you have a defective battery. I bought a MacBook Air M1 and the battery only lasted about 5 hours. I took it back to the store and they said it was defective. I was given a new one. Now I get about 14 hours of work time out of it
What about the screen brightness? That can affect battery life a lot, as well. Still, according to Linus video - there must be smth wrong with your M1's battery ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KE-hrWTgDjk.html
@@MarkEllisReviews Problem solved then :). Unless direct sunlight is hitting screens, most devices are ok (for me at least) on 20-30% brightness - which "should" keep macbook on 13-15hrs of continuous usage. Maybe you can update with a further test (?) :)
I've got the predecessor Air with i3. Probably like yourself I've been an Apple client for many years. Honestly I stopped listening to the battery life claims years ago. Mac's or iPhones I never get even close to 1/3 of the promised times.
Make the same test on the 16“ and an intel 13“... then compare the battery life you got out of them to the advertised and see if the ratio is comparable... if you drain the 16“ in 3-4h, the 13“ intel in 4-5h then the battery life and your use case match the M1 Airs battery performance but your workflow is just bad for battery on any laptop...

Nice video. Well I am quite disappointing with the battery of my new air M1. I bought it in January and since then battery lasts just 6 -7 hours only using chrome and word, both in the M1 version and the brightness of the screen at 50%. Is it normal ?? It last much less than my 2014 MacBook aire . I am really frustrated and do not know what to do
I'm having a similar experience, and I am so far very unsatisfied with Apple's response. I only got 5:51 streaming a simple RU-vid video at max brightness. That is barely better than my 5 year old power hungry Dell XPS 9560 4K touchscreen laptop. Everyone is different, but I very often use my computers at max brightness. I don't know how people can even see the screen below 50%. I was expecting at least 10 hours of typical use, and hopefully closer to 15-20. It does not meet my needs of using it for a full day of stock trading using Webull. I certainly wouldn't call the battery life revolutionary, like I was led to believe. However, I can get nearly a full day of heavy use on my 12 Pro Max.
In my personal experience the battery life is just not as good as punted under real working conditions. It is slightly better than a 2017 Macbook Air, which to say it isn't bad but not magical.
I think it depends massively on what you're doing on the laptop and how you use it (for instance, if you prefer the screen brightness a little higher - which is fine).
Dear Mr Ellis, I just came across your video and liked the content. I subscribed to your channel. From what I heard from your I believe that one of the high power consumptions you experienced team from the screen brightness. I have a M1 MacBook Air top spec, for almost 3 months now and I haven't had such a short battery life as the one that happened to you on the video. To be able to compare things, I am a contract management consultant, on Civil Engineering works, which means that for each project/client, I have the following apps running : Autocad Email client Preview Dropbox Teams Excel Word Safari Reminders Notes This addd up to some Gb of files opened at the same time and, as I do not closed them down until the end of each consultancy, which lasts in every 2 months, it means that several projects are continuously opened at once on the computer. An important aspect is that I used the screen brightness 2 dots below 50%. And I have been experiencing between 13 to 20 hours battery life, so far. I couldn't explain the variation, but that's what has been happening in my case. Keep up the good work cheers
I have some constructive criticism for you Mr. Ellis, it may come off as harsh but it is well intentioned. You should drop any sort of apologetic, subservient, tippy-toe, walking on eggshells attitude that you may have in regards to analyzing or DARE I say critiquing Apple products in particular, otherwise you are part of the hyperbole problem. I do believe that there is a lot of deluded hyperbolic circle-jerking going on online in regards the M1 line's battery life and that cognitive dissonance that you seemingly experienced by the end of the video is perhaps indicative of you having drunk too much of the kool-aid. I've noticed some comments down below suggesting for example that you don't need to have "blinding" full brightness on and those types of comments are probably made by Apple apologist fanboys who will do anything to protect the integrity of Apple's self-indulgent claims. On my own MacBook Air M1 I just lost 10 percent in under an hour of RU-vid and web browsing with nothing opened other than Safari and the ever fluctuating Activity Monitor says I have 5 hours and 46 minutes left at this rate (90 percent atm, full brightness). Here's a video re battery tests you may want to check out. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_yLV07YVaJo.html Tis a pity that when reality strikes we have to feel gaslit because of so much disinformation going about. For my taste the present RU-vid tech review landscape seems like a grotesque caricature of what reviews should be, all the tech review people shoot and edit their videos in the exact same ways with the same walking on eggshells, technologically unsophisticated, apologetic shill attitude. Maybe you can aspire to more than mostly everyone else. "Think Different." Best regards.
8 hours battery lasts for me...Such a CRAP laptop. Liars. Yeah sure you can get up to 18 hours a day if you keep the laptop turned off!!!! Why would I reduce screen light, keyboard light etc?!! So, maybe better is to turn it off and keep it in the drawer for 18 hours to have it last as those scammers advertise.
