Sony Xperia Z4 could be world's most powerful smartphone
The Z4 might look like the Z3, but it could be a very different beast on the inside

The Xperia Z3 has only just launched but Sony is already hard at work on the follow-up. It would have to be really, if it's going to launch early next year as expected.

But as the phone exists inevitably details about it have been leaked, including the fact that from 2015 Sony will apparently only release one flagship each year.

That would make a certain amount of sense, given how small the change was between the Xperia Z2 and the Xperia Z3. Having said that it looks like the Sony Xperia Z4 could be quite a substantial improvement.

According to these rumours, which come from Android Origin's "trusted sources", the Xperia Z4 will have a 5.5-inch QHD 1440 x 2560 display, a 64-bit 2.8GHz octa-core Snapdragon 810 processor, 4GB of RAM and an Adreno 430 GPU. So it should be a seriously powerful device.

The source goes on to claim that it will have 32GB of storage, a curved Exmor RS CMOS sensor with a similar resolution to previous Xperia flagships (so around 20.7MP) and that the phone will support Bluetooth 4.1 and LTE Cat.6 connectivity, leaving it equipped to handle LTE-A speeds.

Music to our ears

Apparently there will also be a dedicated amp in the Xperia Z4 and a lot of focus on audio quality, while it will keep the OmniBalance design and retain a similar appearance to the Xperia Z3.

So design aside this looks like a big change. Of course this is all just according to one source, so it can hardly be taken as fact, but that one source accurately leaked the Xperia Z3 Compact, so they have a decent track record.

  • We're expecting the Samsung Galaxy S6 to arrive early next year too.
