@Michael_Wu Very interesting. I agree that it’s quite strange that we both have the same battery wear considering that our usage has been very different. I’ve run mine unplugged most of the time, and I do fully shut it down every night so it can’t be either of those things. I will definitely let you know what support says regarding this.

@OxyMagnesium Huh, very interesting indeed. Our basically opposite usage leads me to believe that the amount the battery cells degrade just sitting over time is significantly higher than the impact of “normal” usage.
Here’s the serial number or whatever by the QR code on the battery, maybe needed to pinpoint a possible bad batch:
FRANBBATA
1121105BW
I could be wrong and this is just a theory at this point. Looking forward to it, thanks!
Although this is correct in some cases it is not quite right.
For example a battery kept at 50% all the time by being plugged in, theoretically would not go through any cycles. Howveever it will still degrade in a few years.
For example it is not wise to buy a Li-ion battery that is more than a year old.
Most claims are very short term tests and the results can be misleading, but I agree that your experience is neither pleasant or expected.
OK Another update:
Decided to try a complete rundown and charge to 100%
The result now shows the battery as depleted 6.1% so that’s an increase of 1% for a day ???
I’ve had a little concern with the battery wear level accuracy. I use HWiNFO64 to measure my laptop and the wear level varies every time I use it. Today it’s at 0.0%, the other day it was at 1.7%, on another day it was slightly higher. I have the charge cap set to 80% and don’t really run on battery very often.
Seems wonky.

5 more days and mine has gone from 6.1 to 7.6
Averaging 0.3 per day ( 9% a month so 20% in two months ) ???
UPDATE:
Now 6 days later it has gone down from 7.6 to 7.4 ???
The spec says a loss of 20% in 1000 cycles I don’t use a cycle in 2 or three days, so 2 or 3 thousand is 6 to 9 years away, but not according to the stats, it will deplete 20% in 2 or three months
UPDATE:
I have now been using the laptop mostly plugged in and the wear has now reduced from 7.4% to 6.6 so that’s a huge ‘decrease’
The mind boggles ???
I’ll keep at this and see what transpires.
Think it was in another thread that someone mentioned the battery is rarely in-stock in the marketplace, if ever. I wonder if this is partially due to Framework might be aware of the [questionable] battery quality issue (unconfirmed), and is trying to source from a different battery manufacture…without doing a recall.
Mind you, the 1000 cycles bar is typically under some degree of ideal conditions. Various temperature, discharge / drain rate, usage pattern will offset that.
I have seen better batteries / cells…ThinkPads, e.g. Sanyo & Sony (made in China). (i.e. it’s not a regional thing, but a battery manufacturer and possibly cell binning / matching matter?)
Same gripes on the Fairphone forum, so likely a global supply issue as has been going on since the COVID lockdowns, no doubt there are other ascpects too.

Batch 3 (Since Sept 29 2021) here and mine is showing 86.2% capacity (13.8% wear). I’ve been using it every single day on battery since I have college and work and the battery usually lasts me about 4-5 hours from full charge. I never capped it between 20% and 80%. 13.8% does seem a bit high on wear imo, not sure if it’s me or if it’s the battery.
Relative to some others it’s fine, much better than mine which is 7.6% in about a month.
However I don’t trust the readings and I’ve never a had a battery than lasts long so the loss of 20% over 1000 cycles seems like a fantasy.
How do they do these tests ???
A battery is a battery, subject to different applications and environmental conditions…but here’s a test:
Tesla battery researcher shows new test results pointing to batteries lasting over 2 million miles - Electrek
Battery Power Online | Accelerated Life Testing of Lithium-ion Batteries
I would like to see the following features in the BIOS:
- Start charging threshold. (e.g. So that the battery doesn’t going into charging mode when it’s at “Stop charging threshold - 1%”)
- Ability to enable / disable fast charging, or have different charging speed.

I was being sarcastic I didn’t expect anyone to know and as for Tesla and a million miles more like a million lies m! Smile you are being recored and we may pay you for a pretty face.
Strangely the wear on my battery is reversing. I did wonder what would happen if I used it plugged in as I didn’t trust the measuring app.
So now it is recording only 6.6% see

@amoun Yeah the wear reporting is definitely a bit suspect; I’ve also seen it fluctuate by as much as 2-3% over the course of a few days. I think its calculations depend on a lot on the depth and speed of discharge, so it makes sense that it isn’t super consistent. So far it hasn’t varied a lot more than that though, so it’s probably at least in the ballpark.
@Michael_Wu You could try removing your charge limit and continue using the laptop normally for a few days, maybe even let it discharge very low. I did this at the suggestion of support and it does seem to have some effect on the reported wear, and though it didn’t change much for me perhaps it will do more for you since your limit is lower.

@OxyMagnesium thanks for getting back to me!
So yeah AFAIK/IME if there’s a charge threshold, over time, the battery wear percentage will drift away and won’t be as accurate as after a full 0 to 100 charge cycle reading.
I think (unsure) I did at least one full charge cycle between my last post and now.
Currenty it’s showing 87.43%, more than the prior 85%.
If accurate, I think 87% battery wear in 8-ish months (while being plugged in almost 24/7) isn’t too great.
I’ll perform a few full 0-100 discharge/charge cycles and report back, hopefully it goes up even more!

Um, after 17 days, wear increased to 9.350% now…
Edit: I was using 80% charge max, for about a week, yet still 
Yeap! that’s my setting 78% and running most of the time not plugged with the same wear in one month.
However: Above I note I have decreased from 7.6% to 6.6% by using plugged for the last week or so, so there’s hope it is just a poor monitoring system than a battery issue.
UPDATE: 9 hours later and it continues to get better. It’s now at 6.4%
I have justt up the top charge from 78% to 90% to what happens
Over 2.5 months from new and running Ubuntu 21.10 and now 22.04 and only charging to 80% the battery is showing 2.5% wear. Used 80% of time plugged in and over night the laptop is shutdown and unplugged, Running on battery I am getting around 6hr use on “Power Saver”
Monitoring using Linux “Power Statistics”

2 days later and it has gonr upi from 6.6 to 7.6 as I run the charge down from 90% to 63%.
I intend to charge to a max of 69% and use whilst plugged in for a week to see what happnes
Shouldn’t have any impact at all since laptop is running off AC power, but battery wear readouts are weird.
