I'm seeking of upgrading from my Tank 3 Pro (broken screen) and am wondering about the projectors of the Tank X and Tank 4 Pro. They both are higher resolution and brighter than the Tank 3 Pro but smaller batteries.

The Tank X has a 17600mah battery and a 1080p 220 lumen projector while the Tank 4 Pro has a 11600mah battery and a 720p 100 lumen projector.

So my question for those who have either the Tank X or Tank 4 Pro is, how long does the battery last while using the projector?
