Well as a recent, VERY happy OnePlus convert from Samsung, MOSTLY due to the FAR better battery, charging speeds, SLIGHTLY bigger screen, camera being a LOW priority and of course the seeming 25-30% price across the board. I've been anxiously awaiting the OP13 and it's 8 ELITE ( 4 ) chipset BUT if they've somehow made the 8 Gen 3 run near or equal to the Elite, I wonder why I shouldn't save the 2-300$ and purchase the 13R. Although the screen size difference from 6.85 - 6.78 DOES smart slightly. I love bigger screens, to a point of course. I'd wager a 8.5 inch screen would be tough to hold.
The OnePlus Ace 5 will launch as an affordable alternative to the OnePlus 13. However, it will not only be able to match the flagship in terms of gaming performance, it will also have a charging feature not available on the OnePlus 13.
