The TRUTH About Battery Life: Sony a7 IV VS. a7S III, a7 III

What kind of realistic battery life can you expect out of the Sony a7 IV?  How does it stack up to other popular Sony Alpha cameras like the a7S III, and the a7 III?  And furthermore, are there any unique hacks or tricks that may extend battery life a bit longer when using these cameras? In this video, I'll go through what results I found testing the battery life on the a7 IV, a7S III and a7 III and the range of results I witnessed doing various tests recording 4K 24p footage.  I'll also discuss the many conditions and factors I used to make testing this as consistent as possible across each of these cameras.  And, I'll discuss the one mode in particular that may help to get a little extra battery life out of certain Sony cameras. For those thinking about cameras not covered here like the FX3, a1, a7R IV and a7R III, a9 and a9 II - all of which use the same Sony NP-FZ100 battery - this should still provide good insight into what battery life you can expect using those models as well.
