We briefly glance at the warnings as we pull the battery out of its fancy packaging.

Questionable batteries will apparently explode when installed.

This is a 3.85 V, 10.78 Wh battery. Samsung touted a better battery-saving mode, but failed to specify the life of this guy in its advertising—listing the battery spec as 2800 mAh.

This is a slight upgrade from the S4's 3.8 V and 2600 mAh (9.88 Wh) battery. Advertised at 7 hours of talk time, and up to 12.5 days of standby.

We install the new battery. Then, we take it back out. This teardown has places to be and they're under that battery pack.

For those keeping track at home, that took a grand total of 10 seconds. Beat that, HTC.
