Google has a different take on the "pull to remove" battery tab: a perforated portion of the sleeve that, when peeled away, becomes an impressive pull tab.

Two strips of fairly strong adhesive secure this HTC-made battery, but the pull tab does its job without heat. (And may do double duty as a tamper-evident seal?)

This 13.28 Wh battery beats out the 11.1 Wh iPhone 7 Plus, but not the Galaxy S7 Edge with its 13.86 Wh powerhouse.

Worth note-ing, the exploding Samsung Galaxy Note7 packed a 13.48 Wh battery before its untimely demise.
