6Wh are 6wh, reguardless of voltage.

For the cell, yes. But when that needs to be converted to other voltages for the components, then I’m not so sure. There’s energy loss / different component efficiency at different voltages…but I could be wrong. Or maybe the effect is very negligible with such a small difference in cell voltage.
I honestly don’t know…I’m asking. Something around DC-DC conversion efficiency…

Could check by looking at some of the electrical documentation, but these cells should run in parallel so the overall voltage difference might just be ~18V to 20V, and Vsys is already 20V. Whatever power management/delivery probably performs very similarly at those two voltages.

DC-DC efficiency is a thing, though with the ones I worked with load played a much bigger factor in efficiency than a tiny difference in input voltage. But anyway, the difference is going to be a couple percent at most if even that and is pretty much going to drown in the manufacturing tolerances of the battery.
Where did you even get the information that the capacity change comes with a voltage change?

This article mentions a new 4.45V cell voltage, i believe the old one was under 4.

Right, derp.
4.45 is pretty spicy, I really do wonder what they define as one cycle now, 80% capacyity after 1000 100% dod cycles sounds very unrealistic to me, especially at that spicy a voltage.

The increase in battery voltage is 0.05V from 4.4V to 4.45V whilst charging so about 1%. It says, somewhere the 11% (10.6)%
As the voltage difference is very small 0.05V I doubt there will be any dif.
Personally whereas the 55W I have can be 17.2 V I limit the battery to 16V and I don’t think that running at this lower voltage will impact the capacity to any noticeable degree.
In fact since I have reduced via Battery Charge limit the max voltage by 0.1V the wear is reportedly reduced. ???

Yes there is no statement as to what charge level was used to get 20% loss after 1000 cycles, however after 13 months and 62 cycles I have ‘apparently’ no wear, I’m expecting 2% for the first 100
The 55W battery has a max charge voltage of 4.4V/per cell and 17.2V
for the battery.
Though for the 61W the charge may be increased overall to 17.4V it does not mean that once the charge is off the battery will not be much the same as the 55W

You did say you charge to 16v, so you are significantly undercharging the battery, given that it would be pretty alarming have any measurable wear after just 62 cycles even if they were full dod (from your limit of course). You definitely do lose some capacity from undercharging like that, it’s not free but probably worth it. Also you can always do a full charge when you know you’ll need it.
rule of thumb with the 4.2v cells was you’d about double the cycle life for every 0.05v you drop the max charge voltage. Would be really interesting to see a capacity map of that battery, if it’s anything like most of the batteries I have mapped the capacity per voltage falls off a cliff above 4.15 but those were mostly 4.2v rated cells.

I do a full discharge and charge 100% every few weeks. It is since then that my wear has gone from 7.4% to 2.7% ( It was 3.4% when I received it)

By wear you mean just what the battery reports as energy full or something else?
A full discharge and charge lets the fuel gauge chip in the battery re-calibrate and give more accurate numbers, it doesn0t change the actual state of the battery except for the wear it puts on during that, doing it every couple weeks just for that sounds a bit excessive to me.

It may be. By wear I mean
As for the effect of re-calibrating the chip stats, it seems that just about ever time I do the recorded wear is less
In the post above I gave a link which also points to the raw data I have collected for 13 months, multiple times a day with varying charges.
This month … the page has link to the previous month etc.

You guys are really over stressing your battery fears. 
And this is in a laptop you can swap the battery over so easy…
Kind of funny when you think about it.

besides, the elephant in the room is idle power, which is what brings battery life down. hopefully it’ll improve, but who knows.

If I pre-ordered a Framework 13, does that mean I have to buy a matte screen later?

Hi and welcome to the forum.
Not if you pr-eorder the 13th gen which only have a matt screen option, else yes if you buy an 11th or 12th Gen

As someone who bought the 4kg hinge, I would like to know whether the new 3.5kg hinges will have improved performance on the “resonance” issue (Explainer: Lid rigidity, hinge force, the CNC Top Cover, and the new 4.0kg Hinge Kit - #2 by A_Fan) versus the 4kg hinges. If so, it may be worth picking them up, even for those of us who already have the stronger 4kg hinges.

Speaking of the Framework 13 and Matte screen, I am referring to the Ryzen version.
