Support more power efficient CPUs for better battery life (AMD 7840U, ...)

Did you mean “soldered” here instead of “socketed”?

Yes, fixed.

If you make one, I will buy another from you.



This is something that I’m also very interested in. My ideal laptop would be a framework 16 with an expanded battery in the expansion bay and a power sipping ryzen u-series CPU. I’ve spent a bunch of time shopping around for another laptop with a Ryzen U-series cpu paired with a high capacity battery (85+Whr) but have found none. All laptops I’ve found with the U-series chip seem to use a battery of around 47-67Whr. If these deviced shipped with an actually large battery, like 95-99Whr, they could destroy the competitions battery life. But alas I guess I’m part a of niche consumer.

Lenovo do one…

I haven’t seen lenovo pair a U-series cpu with a 95+Whr battery. Did I miss it?

I’ve got one here with a 6850U and an 86Wh battery. There’s a 7040 series update due to be launched soon.

Which model number is that? The T14 Gen 3 is the only one I can find with that CPU, but it has a 40Whr battery.

T16 Gen 1 with the 86Wh battery. Gen 2 version coming soon.

It was a little difficult to track that down to the correct page, but you’re right, thanks for the tip!

What’s your battery life like on there?

We have heard some doubts here, that there may be no relevant market for a laptop with large high-quality display, large battery and low/mid-performance CPU.

I believe we can be sure by now that there is actually a relevant market for exactly this device profile!

Lenovo’s T16 is not a niche product, but rather a core enterprise standard laptop, produced and sold at large volumes. Lenovo would certainly not offer this laptop configuration for this product if it was a niche usage profile.

So framework, it would be superb if you extend the FW16’s configuration with a mid-power/mid-performance CPU configuration.

There are certainly many users who need high battery life and large display, but not a max performance CPU. The FW16 as a product would only profit from this, opening to many more customer’s usage requirements. Not everyone who needs a large-display professional laptop wants or cares for gaming, AI, professional rendering. I would even assume, the majority of users does not have any of these 3 use cases. I f. e. have no use case in gaming, rendering. I care for AI, but I wouldn’t start the compute-intensive stuff on laptops, because they are much too slow anyway. For model training I use cloud vms, if I would want to work locally, I would use an eGPU, so no mobile use case anyway!

Good. I’ve had a full 8 hour day of light use in the office including an hour in a Teams videoconference. Still had 30% left when I went home.

Huh, with that battery capacity, I would have thought it would be much better than 8 hrs…

I recently bought a thinkpad T470 with a 96Whr battery. With my software optimizations, I can get the draw down to ~4W of light usage, yielding about 24hrs of battery life. If I wasn’t buying the framework, I’d be buying the Thinkpad 16 Gen 2 (AMD), and I’d anticipate it’s power draw being similarly low (the lower-power display options may be a requirement).

8 hours on 70%. Do the maths and it’s good for nearly 12 hours. :wink:

I mean, that’s good, but certainly not making Apple worried. I’m hoping to find an AMD u chip solution that’ll easily get me 14 hours. Still waiting I guess…

That’s unoptimised as it’s a locked down corporate machine, just using Windows 10 on the default settings. It’s a work tool that gets me through a work day with plenty to spare, I’m not going to mess with settings that can impact the stability trying to eke out an extra 20 minutes even if I could.

15 years ago, I was lucky to get just over 2 hours on a similar form factor laptop.

It feels to me like battery life has been treading water. I have a laptop from 2018 with a 3K 13.9 inch screen with roughly 57 whr battery and Intel U series i7 that gets me 10 hrs of battery life in light office work even after all these years. Amazingly, the 2023 successor to that laptop, while much faster, actually gets less battery life per reviews.

I was heartened that some recent AMD u series chips are getting 12-13 hrs battery life like the Framework, HP Elitebook, Thinkpads (although I hate their keyboards) and came here hoping to see the u chip end up in the 16 inch Framework, but I guess it’s not meant to be.

I’ve also been somewhat dysphoric that real world users battery lives with the AMD u chips seems to be closer to 8-10 hrs than what reviews are getting (and those chips seem to be a mess with Linux right now).

Given I already have an i5 Dell XPS at work that gets me 8-10 hrs, I guess I continue to hope and dream for a truly all-battery-life-conquering AMD model :frowning: .

To be fair most manufacturers target 7-8 hours nowadays as it’s enough for most work and college/university days. Most people don’t need a 99Wh battery and the extra weight it entails.
