LG will unveil the G4 later today at a press event in London, but thanks to an early leak, we already know all about the South Korean company’s next-generation flagship. If you’re a G-series fan, you’re going to love it.

Just as we anticipated, the G4 boasts a 5.5-inch Quad HD display just like last year’s G3, but it employs LG’s new display technology, which promises greater image quality. Sources speaking to Mashable say the device will also be powered by a six-core Snapdragon 808 processor.

That’s somewhat surprising, given that rival flagships like the HTC One M9 and even LG’s own G Flex 2 are using the top-of-the-line octa-core Snapdragon 810. But it’s thought LG chose the Snapdragon 808 due to ongoing heat issues with the faster model.

Other internals include 3GB of DDR3 RAM, 32GB of onboard storage, a microSD card slot — unlike the Galaxy S6 and S6 edge — and a massive (and removable) 3,000mAh battery that is expected to deliver around 440 hours of standy time, and 14 hours of talk time.

The G4 also boasts a 16-megapixel rear-facing camera, and like the G3’s, it boasts laser autofocus. It also features that “professional grade” f/1.8 aperture LG has been teasing us with, while the handset’s front-facing camera is an 8-megapixel affair.

“There are sure to be a few surprises to be learned” during the LG event later today, Mashable says, plus details on pricing and availability. But as far as the G4’s hardware is concerned, you have it all here.
