Our oversized suction cup makes a second appearance for this stubbornly adhered battery. That, plus some isopropyl alcohol insertion, are just enough to free it.

It's gruesome glue, and almost looks like Venom got a hold of this battery and just won't let it go.

This ultra-large battery boasts 5000 mAh running at 3.86 V, for a total 19.30 Wh.

That's a huge increase over its contemporaries—most notably the iPhone 11 Pro Max at 15.04 Wh, and the Galaxy Note 10+ 5G at 16.56 Wh.

Looking around the fringes of the phone for any hiding bits, we find a millimeter-wave antenna stuffed along an edge next to a copper heat diffuser—a very familiar arrangement.
