I’ll assume it’s cool, but currently hugged to death for me. Just wanted to point out batteries are replaceable even if glued, fixed my GrapheneOS Pixel7 after it killed itself (spicy pillow) charging in heat in a warmer country. iFixit kit + video worked, then got a Chargie which lets you set a temperature above which it will not charge (33C for me, only charges at night in summer). Probably relevant in your case.
