Just adding my personal experiences with this issue to the thread…
I have a 2023 Framework 13 (12th Gen Intel) that I initially installed Ubuntu 22.04 on, and later upgraded to Ubuntu 24.04.
I’ve been having a similar issue with the battery charge sporadically reporting a value below 10% for a second or two before going back to 90+%. The graph of the charge (according to the “Power Statistics” application) looks like this.
I see this behavior whether I’m discharging the battery or have my power adapter connected. I have set my battery charge limit in the BIOS to 96%, which is why the graphs never get to 100%.
I changed my battery from the 55Wh unit to the 61Wh unit about 2 months ago, and have continued to see this issue.
I saw the issue when I was running Ubuntu 22, and have continued to see the issue after upgrading to Ubuntu 24.
I’ll have to check and see if I see the cros_ec_lpcs cros_ec_lpcs.0: packet too long error that others have reported seeing in dmesg.
Just want to report I’ve also been seeing this regularly on an 11th gen i5. I very rarely use my laptop without the charger plugged in. Max battery percentage is set to 85% and I use either the Framework charger or a Steam Deck charger which both keep the laptop at 84 or 85%.
Every 20 mins to half an hour I get a random single-digit battery percentage reported, asking me to shut down or hibernate, and the following messages:
[97327.451094] cros_ec_lpcs cros_ec_lpcs.0: bad packet checksum f7
[98371.937386] cros_ec_lpcs cros_ec_lpcs.0: bad packet checksum f7
I’ve had these or the “bad packet length” messages for the memorable past (at least a year, maybe 2) and I’m somewhat surprised it hasn’t been fixed yet.
I’m seeing this (Latest Kubuntu LTS, 15-1135g7 FW 13) too. sometimes KDE will just send me notifications about low power and the status bar icon will show a battery empty symbol. if i unplug something like an ethernet card it recalculates itself and seems to figure itself out but i definitely worry that it will shut down my computer at some point (and i suspect it already has a couple times when i wasnt around to react quickly enough)
I’m seeing a similar error on my AMD HX 370 Framework 13, where when I transition to battery power, I will get a battery critical warning, even though the laptop is at 90% charge.
This is with Fedora 42 and KDE Plasma 6.4.4, kernel 6.15.10-200
I have experienced this a few times in the last couple days as well. I have the Framework 13 with AMD Ai 350 cpu. And I am running arch Linux kernel 6.16.1. I don’t need to be transitioning from charge to battery. It has only happened to me while on battery power so far. Once when the battery was at around 70% it went to 0% and popped up a critical warning and was going to hibernate. I hit cancel and the battery went back to the proper reporting. Then it happened again around 23%
Looks like I’ve got the same issue (Bluefin, FW13 Ryzen AI 300 series). The laptop doesn’t shut down, but I get a popup saying the battery is empty… which disappears as soon as it pops up.
Luckily, the laptop doesn’t shut down, so it’s a purely visual bug in my experience so far.
Just to chime in, I’m having the same issue on CachyOS with kernel 6.17.7-2-cachyos running KDE Plasma. I’ve only had my framework 13 for a few days now, but it happened for the first time today. Not sure if it’s a regression regarding the fix @jubnut linked or something else entirely.
