Hi, my ~2 year old battery's full capacity in a Lenovo Yoga 510-14IKB has been dropped from 52500mWh to below 22000mWh by the time I noticed it yesterday. In less than 24 hours since I noticed this it lost another ~2%! Other than the ridiculous capacity it works fine, I can't observe rapid discharge, sudden drops, or insufficient recharge. That's why it wasn't obvious to notice this. What can I do? In BIOS, or anywhere else? I couldn't find any process for e.g. calibration in Lenovo Vantage (like it was written in previous posts related to its predecessor the Onekey Optimizer). I'm shocked at the extent of the wear...
I also installed Lenovo Diagnostics, but it failed:
Final Result Code:

Hi, thx for your reply! First earlier today I settled on the same conclusion (even ordered a new battery), but since I posted here I've investigated a bit further. I never let my devices powered by Li-Ion batteries get under 10-20% level of charge. But after investigating many related problems I started to feel that a recalibration of the battery would be one of the last things I could try before the ultimate hardware solution: replacement (I can still call that off I think). So I started the process and tried to fully discharge the battery - BUT when it reached 6%, it has stayed there! It says '6% 12 mins left' for well over half an hour now... It's close to midnight here, so I won't be able to do the full discharge as I have no clue what's the real charge level of my battery, but tomorrow I'll try to follow e.g. this full process (if you don't offer a better alternative based on the new info): https://www.thewindowsclub.com/manually-calibrate-battery-of-windows-laptops
Or do you have any other ideas to correct this glitch? (yep, it's still solid 6% even after finishing this post...)

We can also try performing a battery gauge reset using the Lenovo Vantage,

Update us how it goes.

Thx, I'd gladly do that, if I could find the option in the menu to do so... That was the reason I installed Vantage today to help me in this problem. Do you know where I can switch language to ENG? Because I can't find your recommendation in the menu in my language: I can get to the Hardware, then Power menu, but I don't have a comparable option that matches your recommended one (Battery Gauge).
In Hardware settings/Power I have (rough translations):
- Power supply status
- Storage Mode
- Quick charge
- Continuously operating USB
- Lenovo Vantage Toolbox
- Other (redirects to Control Panel)
... (Battery is still on 6% percent level...)
Update: for me this didn't help: https://forums.lenovo.com/t5/Pre-Installed-Lenovo-Software/Battery-Gauge-toolbar-missing-from-Vantag...

fyi I contacted the service centre, I wait for their reply. BUT it's not that simple. I'm in the process of making another full cycle:
With low usage my battery went from 100% to 6% in ~ 3,5 hour, then it stayed at 6% for 3 hours with even less workload if possible (just visible screen only a diagnostic program ran besides some processes in the background, no wifi) as I tried to be precise with the calibration process for 2,5 hours, then half an hour of gaming in the end to finish off, because I needed to hurry and I didn't expect it to last this long!
Actually, if we add the 2 durations to each other (6,5 hours including half an hour gaming) the overall time isn't that bad to call this battery totally faulty... Well, if I push it harder this duration surely drops significantly, but still seems bearable... It's strange that the figures fpr capacity hasn't changed during my last attempt, but the juice seems to be there... Now I'm waiting for full recharge to 100%, this time with the laptop off.

I ended my 3rd version of calibration trial (still manually, still no solution for having no option 'Battery Gauge Reset' in Lenovo Vantage...):
1. Full charge
2. Discharge to 4% (forced hibernation occurs for me here, depends on setting), then switch back on laptop to complete discharge to 0% till it switches off
3. Immedately start recharge - with the laptop remaining OFF!! for a much longer period than usual, this time I've let it to charge for 4,5 hours. (Possible explanation: towards full charge the laptop slows down recharging significantly, even if it believes that full charge is close and that's not the reality. Let's give it time; I might wait even more next time.)
Final result: my wear level improved back from the minimum of 60% to 17%! I guess it's acceptable for an almost 2-year-old battery, at least it's much better than it was.
Overall assessment of support: I appreciate at least the intention, but I felt that you would have 'dumped' me to the service centre too soon. Do you know the consequences? A costly, timely examination if I don't accept their repair offer, while if I accept it the new battery would have costed me much more in money and time (lost days) without my laptop for work... That's why first I wanted to exhaust all other options I could. The exception was Hector's advice supporting my suspicion, though in which I would've needed further assistance, as Lenovo Vantage on my laptop lacks the recommended feature. With time investment and uncertainty I found the solution in a situation I've never met, but if I'm not this persistent, I would have been driven away to a much less favorable scenario... At least,thanks for your helpful attitude, I appreciate it.
