86% after just 126 cycles?!
What was you usage pattern?

Different battery chemistry (you’re likely flying lipo vs laptop’s li-ion), which means they react differently to conditions. In any event, I treat my laptop pretty well and it only ever gets used or left to sit in room temperature.
I also set it to 60% limit in bios when I know I’ll be using it docked for an extended period, but I put it back to 100% when (like now) I know I need to take it and have a work day of battery life.

I’m sure you know that the capacity report is pretty inaccurate unless taken in specific conditions (which I no longer feel safe to set up), so that’s what was on my tlp report at 99% charge after booting up.
Usage pattern varies between leaving it at a limit of 60% and plugged in and a limit of 100% and using the full battery over 8h before charging overnight.
This is probably one of the first 61Wh bats framework made given that I preordered the day of their early (erroneous) announcement and preorder open, so maybe it was a bad batch.

If you do full discharge charge cycles somewhat regularly it should be reasonably close.
Hell for science it would be worth doing one just to find out how much capacity is actually left now.
That could be an explanation, I suppose we’ll see a bunch more reports soon if this is a widespread issue.
Battery is puffed, I’m not charging it for science because I don’t want my mainboard to look like a science experiment.
Actually, it already does look like a science experiment gone weird

Your call, just being puffed doesn’t make a battery particularly dangerous to charge and it would be interesting.
Mechanical damage on the other hand is a whole other story XD.
Mine is slightly worse.
Received Feb 2022 Batch 8
90% of the time plugged in at 78% max charge via bios.
I used to reset by discharge and recharge once a month, all was fine then it shot up to 12% with 106 cycles ???
Yours isn’t puffed though XD
Not that I can tell, keyboard is flat 
Not going to look inside. maybe the 78% saves me from a 100% charge in 32° day temp to 6° night temp in the winters.

Gets one of the easiest to open laptops, refuses to look inside.

Why mess with what’s working ?
I didn’t refuse as I wasn’t asked and who is rude enough to ask me to do the unnecessary.
Opened it once to change the input cover, why are you being so rude, personal and off topic?
I have a 61wh battery in a project of mine, and swelling is a real concern, which is actually quiet common in general. However, I limit the charge capacity to 60% because I don’t want to exacerbate swelling.
The change of temperature affecting swelling really makes a lot of sense. This stuff doesn’t just apply to Framework batteries, but batteries in general.
Still really unfortunate Be_Far. I wonder what your ambient temperature is normally?

I am sorry you perceived my little joke as rude, it was not meant that way.

I live in Texas, so pretty sweaty outside, but I’ve never used it nor left it in that weather/in a hot car etc. room temp at 68-70 degrees?
I’m out of the country right now (which means I have to order a battery rather than swapping back to the 51 ugh), but temps are very mild here at the moment so I have no idea what brought this on.

Most of my science experiments end with the smell of burning plastic and a ring of soot that won’t come out of the driveway for a few rainstorms… I need this laptop for school haha

Well. Happened to me sometimes too when an airplane crashes and the battery has a short.
Usually, if you’re fast enough to rip the battery out of the plane you can save the rest. But sometimes, it just burns. I had some warbirds burning like that. The irony though
Slippery slopes. I had to quit the Fairphone forum for similar ‘sarcastic’ jokes. And once I’d made a few the moderators were all over me. UK humour is not the same as the EU, no wonder we left.
More tears, like the rain in the South west UK it rarely stops, but there are bright days and sarcasm is fine, just do it with a smile
Update, I replaced the battery at the beginning of last week (it shipped in record time!), and the old battery is being properly recycled. Here’s hoping this one lasts more than a year.
@Adrian_Joachim as an indicator of how inaccurate the battery stats are, tlp-stat shows my current capacity as 101.1% after 1 cycle (it’s been 6+ cycles so far…)

On new batteries capacity usually does increase a bit and 1.1% is not much. Also that figure messes with the cycle count I imagine.
