Battery life is inline with the K1 Shield tablet and its 5200mah battery. You can see the internals of the K1 here: https://www.ifixit.com/Guide/Nvidia+Shield+Tablet+Battery+Replacement/50117 https://www.ifixit.com/Guide/Nvidia+Shield+Tablet+Battery+Re... The X1 Shield tablet's FCC filing show it also has a 5200mah battery so I'm guessing the layout is similar to the K1 and the Switch (the Switch filing just says the battery is non-removable). Whatever the design, I hope it's better than Nintendo's previous handhelds which had a lot of blank circuit board where there could have been more battery volume: https://www.ifixit.com/Guide/Nintendo+3DS+XL+Motherboard+Replacement/25399 https://www.ifixit.com/Guide/Nintendo+3DS+XL+Motherboard+Rep...
