Pros
Pro Fantastic battery life
With the exceptionally large 4070mAh battery paired with the efficient Snapdragon 821 processor, the LeEco Le Pro 3 gets amazing battery life. It's still a new phone, so there aren't many user testimonials yet, however TechTablets got 11 hours of screen on time (about 3h30m of that was real world use, and the rest was the screen on but idle).
Cons
Con No headphone jack
Following the iPhone 7 and Moto Z, the Le Pro3 doesn't have a headphone jack. To use headphones, you have 3 options:
Use an adapter that plugs into the USB port on the bottom, and plug your headphones in there
Use headphones that have a USB-C connector instead of the traditional 3.5mm headphone jack
Use BlueTooth headphones
Con Quick settings and recent apps awkwardly merged
On every other Android phone you can access quick settings from the notification panel, but that isn't the case here. Instead, this has been moved to the recent apps button - pressing it will bring up a few recent apps across the bottom of the screen (you can only see 3 screens at a time) with quick settings across the top.
