Compare Mobile Phones Side-by-Side

The Oppo A6t Pro 4G is the easier phone to recommend here, mainly because it fixes the two areas that will matter most over time: memory and battery. Both phones give you the same large 6.75-inch 120Hz display and both use a Qualcomm processor, so the basic feel should be similar when scrolling, watching videos, or handling everyday apps.

Where the A6t Pro 4G pulls ahead is with 8GB of RAM instead of 4GB. That should make it noticeably more comfortable for multitasking and keeping apps open in the background, especially after a year or two of use. The 7000mAh battery also gives it a little more breathing room than the already-large 6500mAh pack in the A6x 4G.

The Oppo A6x 4G still makes sense if it is significantly cheaper and your usage is light. But if the price gap is reasonable, the A6t Pro 4G is the smarter buy and should age better.
