Maybe, but 4-5 hours is solidly the point at which it doesn't matter at all to me. I haven't had trouble finding an outlet for years, even at airports, planes, coffeeshops, etc.

I travel a lot. That’s going to be increasing by the end of the year as my wife and I live the digital nomad life flying across the US. The freedom of not having to worry about your battery life for a day of real world use is amazing. I’ve only had that over the years with an iPad before ARM Macs. Not to mention your laptop not getting hot enough to boil eggs or sounding like a 747 when you open too ,any Chrome tabs.

When depending on solar it’s pretty important to be low power, m1 drawing 10-20 watts vs something else drawing 60-80 can make a big difference on batteries

After Apples announcement of M1, I feel like it is mandatory for such a laptop test to discuss power per watt and for how long you can game on the 11 vs 12th gen processor. I also feel like it is worth mentioning that 12th gen laptop is priced ~ $150 over the 11th gen. If you're coding against an online build system and 11 last an extra hour (or whatever), it's a no-brainer to stick with the old one.

You can't game on M1 or Mac AFAIK

I game on my m1 macs. Maybe not the latest and greatest 3d games but for me that’s ok. Have a ps5 for that. there are a ton of older ones that just work, and even many newer ones. Currently playing baulders gate EE

I don’t like that we call it 12th Gen Intel. It would be more correct to just call it the 12000 series Intel. Intel didn’t change CPU generations from 6000-10000 series, they’re all the same generation. Just because the years advance and they refresh their products with increased product numbers doesn’t mean that they’re a new generation of products.

Aside from being pedantic, why is this relevant? I'm sure most people that care enough know that it isn't Intel's 12th generation.

Exactly. Not just 1 model but you can compare identical ThinkPad models as well and AMD versions have significantly better battery life. Not only that, even last year's identical models with 11th Gen Intel CPUs have better battery life than their new 12th Gen models. So Intel's power efficiency actually decreased compared to last year, even though they introduced the hybrid architecture. In some instances Alder Lake…

These numbers are usually lower in real life There are data sheets and then there is real life. People were raving about AMD laptops before. I got a ThinkPad T14 AMD with a 4750U. The stated psref battery life is MobileMark 2014: 14 hr, MobileMark 2018: 11.5 hr. In practice that was more like 7 hours on Windows (with a mild workload) and 3 hours on Linux. The CPU performance was merely ok and I could get the fans blo…

Lenovo ThinkPad T14 AMD Gen 1 here. My experience is totally different, using Fedora 36, everything works! Battery life I have no exact numbers, but definitely way more than 3 hours.

The freedom of running Docker on a laptop without heating it to 60c is too tempting, unfortunately. My Macbook will get 2-3 hours of battery life over my Thinkpad, but my Thinkpad also doesn't burn my palms with regular use. It's a game of tradeoffs, but I rarely find myself reaching for the Macbook if I've got a desktop close by. Maybe that's a skewed perspective though. I have yet to try the Pro/Max chips seriously…

What type of battery life are you getting on an Mx MacBook?

I'm getting about 10 hours on my M1 16" MBP running a JetBrains IDE and 8 Docker containers.

Since this is Hacker News and a lot of people here runs Linux, I want to remind everybody to hold your horses before you tested Linux on these machines. The machine that I'm currently using comes with a Ryzen 6800H CPU and LPDDR5-6400 RAMs, made by Lenovo.

My AMD Gen 1 has been nothing but trouble under Linux. But it's not CPU, it's Lenovo. Lenovo has terrible firmware team.

My experience is otherwise, see my comment above.

I've played with an AMD 6800u laptop and I would say it's the ideal x86 laptop chip right now. Normal usage at the 12w mode or light gaming at 20w mode was super impressive. Even though 12th Gen Intel chips have made great performance gains Intel is still relying on unsustainable high turbo boosts to get the benchmark numbers. I just recently stumbled across these two otherwise identical laptops. https://psref.lenovo…

If you don't mind, can you test Ubuntu or Fedora to see if the issue is present?

The reason I'm asking, according to a Lenovo talk from DebConf22 [0], the guy said it takes some time for patches to reach upstream, but with Fedora and Ubuntu they have some connections to shortcut some patches before they reach upstream.

I used to think this as well, but the all day battery life on M1 really made me realize how much of a mental tether outlets used to be. It seems pretty minor, but not worrying about getting a seat at the {coffee shop/airport/lounge} next to an outlet makes working on the go a much more attractive option now.

Don't power banks achieve the same and more? They are a bit heavy,but it sounds like it should be worth it to you.

In a laptop, I care far more about battery life and the fan noise. However, Intel 12th gen is only able to pull these impressive performance feats due to very high turbo boost clocks. It's not that Intel is bad, it's still pretty great but in the age of M1 I wish Intel released a processor with similar power consumption. I use my Intel i5-1240p with turbo boost disabled when on battery. Here's the geekbench with TB d…

How is 12th gen compared to 10th gen, in your experience? My XPS 13 on a 10th gen i7 just becomes absolute syrup on battery, even if I put it in high performance mode.

I have an XPS 17 with 12th gen and it drains around 50% battery per hour on a zoom call.

edit: My laptop has a i7-12700H, which uses more power than the cpu in the framework laptop.

More thoughts: The laptop is pretty much always plugged in. When I'm out I carry a little 60W charger with me.

However for other reasons I wouldn't recommend the XPS 17. I have a Lenovo legion 7 at home that I'm more happy with (cheaper, better performance, lots of ports, etc)
