Apple may have packed bigger batteries into the iPhone 7 and iPhone 7 Plus, but one Chinese company says it can do better. LeEco released a teaser for its upcoming Le 3 Pro on Wednesday, promising better battery life and taking a direct shot at Apple.

The image appears to show a big battery literally squashing an apple. The image mocks the iPhone 7 for packing a “mini” battery that only offers one extra hour of use per charge. Near the bottom of the teaser, the company hypes its own device, which is set to launch in seven days on September 21.

LeEco doesn’t actually reveal what kind of hardware its new phone will offer, but we may already know thanks to recent leaks. The Le Pro 3 is expected to come in two main variants, with the cheaper allegedly packing a 4070mAh battery, a 5.5-inch 1080p display, a 16-megapixel rear camera, an 8-megapixel front-facing camera, a Snapdragon 821 chip, 6GB of RAM and 64GB of storage. The higher-end model could boast a 5000mAh battery, a 5.7-inch 2K display, 8GB of RAM and 256GB of storage.

That should add up to a pretty powerful smartphone. It certainly puts the iPhone to shame spec-for-spec, but Apple may still have the edge thanks to its tight hardware-software integration. If battery life is extremely important to you the Le Pro 3 may be the way to go, though we still don’t know if this device will ever make its way to the U.S.
