What would also extend life time of smartphones is the ability to replace the battery! But I guess this is just too radical of an idea for present day.
Nice they are able to get the most from the battery lifetime, that also helps to reduce waste.

They also could double battery capacity. This would lead to somewhat larger and thicker smartphones, but the battery would last much longer, because it is used at much lower rates.
A little off-topic but the day’s not far away when Lithium-ion batteries will cease to be used in smartphones and that, my friends, will be a good day. Basically, Lithium-ion is getting expensive because the raw materials are getting expensive and extending battery capacity(and battery life) while keeping the costs as low as possible is becoming hard(and the improvements in Lithium-ion batteries have remained almost unnoticeable, well it took more than a decade for manufactures to be able to double the battery capacity at first while other key components like CPU etc improved a lot more) and it has become visible during the COVID-19 pandemic. While Oppo’s solution might be good for now, we need to actually switch away from Lithium-ion itself for sustainability and such. TechAltar has made a good video about the batteries in smartphones which I definitely recommend anyone, who is concerned about smartphone batteries, to watch. Here’s the direct link to the video.
