I usually use GSMarena for checking the specs of the phones that I’m interested in, and GSMarena shows that all these phones use Li-po batteries. But I’ve seen teardown videos of these phones and in that the batteries of the phones have Li-Ion labelled on it. I’ve only seen Li-Ion batteries on some of the more expensive phones like the S series, so I was wondering whether the A series or atleast these three phones use Li-Ion or Li-po.
