0.9V on a lithium cell? And it still charged? …
I wouldn’t be able to sleep under the same roof with these recovered cells charged again, being scared they could catch fire.
Next time just replace them, maybe upgrading total capacity if you happen to open the device anyway.
Answer: no. Huawei equipment is not the best in class. Cheapest? Maybe. Cheapest as in Total Cost of Ownership? No, good luck with their quality.

But mah profits!
737 Max is still a developing example of what happens when you leave corporate to self-regulate themselves.
Ah yes, Harold :) I forgot

Thanks for sharing this.
It looks like the cutoff voltage for LiFePO4, the minimum voltage after which there should be a total power cutoff is around 2.8V. Discharging further is equal to more or less serious, but always, damage to the cell. It also looks like the effects of such over discharge might be less serious for LiFePO4 than it is for Li-Ion cells. However… doesn’t this 1500$ device have a Battery Management System, BMS, a small circuit to implement the cutoff voltage? What the hell?
