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

Blockquote

I’ve had the laptop since mid-late September 2021. 11th Gen i5. Same Battery. My version is the same version as well, its odd you don’t have that last row. I think it just mimics what Windows is reporting though. I am on Windows 11.

Suggest folk update to 3.09 BIOS so they can post the cycle counts to give more context to the provided numbers.

Going to do a full discharge / recharge cycle and see where my battery is at with the wear.

Not really related but I was using my laptop with a little constant power usage (say 15% CPU and 40% GPU) and battery drop was 1% a minute (at 80% charge limit). First time I’d really done a little heavier lifting with it.

Quite surprised how fast it dropped. Especially as I have switched off the turbo boost so the highest it goes is 2.8GHz.

I’m sure that means something to someone. :joy:

It was dropping around 1% a minute on the several occasions during the work I monitored it.

Full charge capacity at the moment (after a full discharge / recharge cycle): 52,853 mWh

So that’s at 3.9% wear.
Cycle count: 38

(First powered on: 10 months ago)

@Kieran_Levin, I noticed the following behaviour, not sure if it’s expected by design:
Laptop battery was intentionally discharged, fully, by letting the laptop stay on…till it ungracefully powered down. All good so far. Then, upon pressing the power button, the power button was flashing red, and the laptop didn’t come on. Still good, as expected so far. Plugged in USB-PD expecting it to charge. Came back an hour later. Powered on the laptop. But it’s only at 2% charge. It’s as if the laptop didn’t start charging until it was power on. This was unexpected. (On BIOS 3.09)

Expected behaviour: When the laptop’s main battery is fully depleted, and the laptop can’t even complete a POST, the laptop should be able to start charging the battery when USB-PD is plugged in, with or without the laptop being powered up.

I have 3% battery wear, daily use since the start of the year for 2-6 hours each day.

I don’t think the battery wear information can be very accurate in general, 11 months on my computer shows 2.6% wear at 53577mWh. I never lowered the max charge and use the computer in my classroom 5-7 hours a day from last October through July.

I think these are only accurate to within a few percent, because there’s no way I have lost 1.3% of wear since I posted 6 months ago.

Just thought I’d throw my anecdotal two cents at everyone, anyway. Can’t complain that my battery is reversing it’s wear, but here’s hoping the thing isn’t lying.

HWiNFO64 7.22 (I know it’s old, but I prefer consistency, no sense updating if it works and hardware is unchanged) and Windows 11 on 1135G7 for those wondering.

Edit: corrections above and whoa 100th post. I’m such a child for being excited about it.

Update:

I have been running on battery far more, though with a lower 75% charge limit. Probably another ~100x 75 to ~25% cycles in the last two months.

After charging to 100% and letting it float down to 80%, then back to 100% 3x times today (to let the charge controller figure things out), I am getting 3350000/3572000 health (as reported by cat /sys/class/power_supply/BAT1/charge_* ), or 94% of rated capacity. This means around 4% capacity loss in 4 months since my last measuring and posting on this in April.

Others have said that the battery state of health calculations might be a bit inaccurate, and my suspicion is that this is true as well. Not sure how to improve the accuracy of the reporting, either installed in chassis or through bench testing, but it might come to that if we need better degradation data.

I am at 98.2% after about 7 months. Running Ubuntu 22.04.1 spending a lot of time on power with a charging limit set to 80% and running on batt about once per week and getting around 6 to 7 hrs use from the battery. :blush:

I was in batch 3 and was using mine daily for a day short of an entire year now (Got it Sept. 29, 2021). I’m at 89% capacity so 11% wear.

I’ve been using it daily for college and work and charging to 100% and usually using it until it’s around 20-30% charge though some days I went as low as 5-10% due to not having access to a power outlet.

Batch 2 i7-1165, 97% battery health remaining. Semi-regular daily driver. Charge to 100% and drain from there. Variable drain lengths before re-charging depending on how long I know I’ll be from a wall socket.

Mine is from the first I5 batch

POWER_SUPPLY_NAME=BAT1
POWER_SUPPLY_TYPE=Battery
POWER_SUPPLY_STATUS=Charging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CYCLE_COUNT=96
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=15400000

POWER_SUPPLY_MODEL_NAME=Framewo

So I guess I’m at 85% of the design capacity after 96 cycles
Yes, I have capped it at 90%

Out of curiousity could someone answer how accurate wear is?
Also wear to my knowledge is hard to calibrate correctly.

Not accurate. At the end of the day, what you really / actually care about is how long you can use your laptop for, per charge. That’s what really matters. Wear level is just a rough guesstimation.

It’s like…mileage of a car…it’s not exact…and what really matters is you want to know if your car will crap out on you, and how much it’ll cost to fix the issue. Mileage is just a rough indicator of likelihood of potential issue.

Or age of a person…you get the idea…

After 6 cycles mine is at 96%

Batteries never come with no wear, that’s around the percentage most people start with so don’t worry.

Technically true because they are at least charged (once or more) at the factory.

However, a lot of the time, a [good] new battery would be able get a full charge capacity anywhere between 1-5% above designed capacity. My Framework laptop was able to get a full charge about 1% above the designed capacity for the first 5-8 cycles.

I joined this thread not so much to mention my battery wear but to comment on the fact that replacement batteries are still not available to buy 15 months after the first computers were shipped. That is incredibly poor logistics.
