How's everyone's [55Wh] battery health and wear looking?

[Brendan]

I’m a 12th Gen Batch 3. My charge-cycles should definitely not be 8. So, as others have found, maybe it’s 263?

[Ultionis]

11th Gen, Batch 2, original battery, almost daily use since November 2021:

DESIGN CAPACITY	55,009 mWh
FULL CHARGE CAPACITY	46,354 mWh

Remaining battery capacity: 84.266%

about 1 year old AMD FW 13… usually plugged in, set battery charge limit to 80%

[Allenx51]

Purchased January 2022, battery level kept between 75 and 80%, used daily, mostly plugged in at a desk. Swapped mainboards from the 11th gen i7 to an AMD board, so I expect that the cycle count is at least 1.5x-2x this.

Not bad I don’t think following a full drain and charge to 100%.

[umbra]

89% capacity left. My Framework is a little over a year old (AMD Batch 2). Daily use for multiple hours, no charge limit.

@Alex_K1

I’m not really happy about this to be honest, as the claims by Framework that the battery is designed to retain 80% capacity after 1000 cycles seems to be a bit misleading. I’m not anywhere close to halfway there!

I think the battery is capable of retaining 80% after 1000 cycles as long as you don’t 100% for a year or but your computer in a hot place. However the battery management might do some shenanigans to negatively affect the capacity

@anarcat

Here’s my rendering of the battery right now, after slightly less than a year of use:

The red line is the evolution of the battery health. According to the current levels, it’s at 3286000 out of 3572000 design capacity, which is 91.99%. You can clearly see “drops” in that line where the battery was somewhat “damaged” in one shot, which is, I think, the most interesting part of that graph.

I found the answer, the “drop” is likely due to the BMS deliberately lower the limited charging voltage after some time or cycle to use only a part of your battery’s capacity, this makes the user think the battery has degraded. The motivation of this is yet to known. If you have the opportunity could you please fully charge your laptop and read the voltage(while still plugged in)? If that voltage is significantly lower than 17.6V(such as 17.4V), then this is the exact problem. My 61Wh battery decided to “degrade” 9% by limiting the voltage from the original 17.8V to 17.6V. The same 0.2V drop is witnessed here(55Wh, 17.6~17.4V).

Note that the full voltage of the battery is no longer 17.6V but only 17.4V. If the original voltage is restored, your actual capacity is likely going to be 52~53Wh.

And here’s the graph, almost two years later, after less than 3 years of use:

You can see it never went back up to 100% after those drops, but the capacity oscillates between 78% and 88% in march. Here’s a zoom of the last month:

I guess that’s 17.38V? And would confirm your hypothesis. The battery is not fully charged right now though, I’m at 93% and charging, will try to remember to update this post when it’s fully charged.

[Richard_Tango-Lowy]

My battery’s an 11th gen batch 5, and my capacity is at 84%. The FW battery has help up much better than any of the Thinkpads, so I can’t really complain.

I borrowed a 3y/o 55Wh battery and here are my readings, the hypothesis is confirmed.

A 95% health battery is “degraded” to 85% due to the max voltage lowered from 17.6 to 17.4

Despite this, the battery still has 84.7% capacity after 1344 cycles.

I hope this isn’t offensive, but the forum won’t let me remove my like from your post. I liked the numbers, but the idea that Framework’s lowering battery capacity artificially because the charging voltage is lower doesn’t follow.

Companies sometimes pull that kind of thing – printer manufacturers come to mind – but there’s nothing remotely suspicious here.

@James_Jarrett

but the idea that Framework’s lowering battery capacity artificially because the charging voltage is lower doesn’t follow.

I don’t think Framework is the one who lowered battery capacity artificially. I think it’s just Framework didn’t know the battery supplier doing this because it’s being done very subtly

@James_Jarrett

I acknowledge your attempt of removing a like from my post, and I agree that undoing likes(and votes) is slightly better in a forum as sometimes the person who liked the post changed their mind or sometimes the post got an edit and no longer likable.

My early 2022 i5-1135 FW13 doing alright. It went down steep in the first months but been stable around 12% since then. I limited charging to 89%. But occasionaly charge to 100%.
