As for the following quote from that blog post:
“the amazing effort Jolla’s adaptation team has put into making the Xperia 10 III run as efficiently as possible (back in December an early Xperia 10 III adaptation was was losing charge 31% faster than the Xperia 10 II).”
having never owned the 10 II, I cannot say how much faster the 10 III is losing charge compared to it, but it definitely continues to lose charge SEVERAL times faster than the XA2 Ultra (which has battery of almost identical capacity as the 10 II). So I dare to say that this blog post was way too optimistic, at least in the power consumption and camera department where nothing has changed.
