Battery level doesn't exceed 93 %

Hi !
I have two Réolink Argus PTs, each powered by the photovoltaic panel.
The two power panels are exposed exactly the same, they are installed side by side. Both cameras are set exactly the same. PIR to OFF.
Can someone explain to me that the battery level of a camera is always at 100% (the oldest), and the second does not exceed 93% (recently purchased).
If I lower the levels, the first in one day goes back to 100%, the second in one day goes back to 93% and does not exceed them.

An idea ? THANKS

@jm_fort_525559425302685 I have battery cameras and when plugged to the solar panel they shows 100%. If I unplugged it, the display shows 92%. I think that there is something wrong in the computational routine. I wouldn't care at all unless the level is less than 60%.

@joseph_1979 I'm not having much luck with my appliances at the moment.
I fear this malfunction will get worse when the warranty expires...
