The Find X7 Ultra already had solid battery life with its 5,000mAh capacity, but the Find X8 Ultra is taking things up a notch. In our battery tests, the Find X7 Ultra was just a few spots behind last year's Galaxy S24 Ultra, so with this 22% boost in capacity, the new model could outlast the Galaxy S25 Ultra, which still uses the same battery as its predecessor.
Of course, real-world results will tell the full story, but on paper, Oppo's latest flagship has a clear edge.
The Find X8 Ultra isn't just about the battery, though. It is packed with serious upgrades. It will be available in three configurations: 12 GB + 256 GB, 16 GB + 512 GB, and a top-tier 16 GB + 1 TB variant, which will also include satellite connectivity. Powering it all will be the Snapdragon 8 Elite chipset.
On the camera front, expect two periscope telephoto lenses – one with 3x optical zoom and the other with 6x. This gives the X8 Ultra one more potential advantage over the Galaxy S25 Ultra, which offers a 5x and 3x zoom setup. But as always, we will have to see how these perform side by side in real-world conditions.
With the launch date fast approaching, we will soon have the full picture, so if you are eyeing this flagship, stay tuned!
