The upcoming Sony Xperia Z3 is the star of a new leak, this time showing the device from all angles and giving us a glimpse of some disassembled internals.

We're just a few days away from the big IFA 2014 trade show, where a slew of companies will take the wraps off their latest and greatest gadgets. The Xperia Z3 should launch at the event as Sony's flagship smartphone for 2014, but recent leaks suggest that it may not be such a big improvement over its predecessor.

The latest leak offers some images in teardown fashion, which are a bit more revealing than regular images showing some angles of the device. It may not be as comprehensive as an iFixit teardown, but it still gives the world a good look at the Xperia Z3's internal components.

If these new images from the Xperia Blog turn out to be the real deal, the Sony Xperia Z3 will be slightly thinner compared to its predecessor, but it will achieve this at the cost of battery life. The new model may come with a battery of just 3,100 mAh, which would be a downgrade from the Xperia Z2's 3,200 mAh unit.

In fact, the upcoming Xperia Z3 doesn't seem like an impressive upgrade at all compared to its predecessor. The new model is expected to pack a faster quad-core Qualcomm Snapdragon 801 processor clocked at 2.5GHz, 3GB of RAM, as well as a higher IP dust- and water-resistance rating, but in other aspects it will remain the same as the Xperia Z2. In the display and camera departments, for instance, the new iteration will reportedly come with the same 5.2-inch full HD panel and the same 20.7-megapixel rear shooter. That's not to say it's not good, but many expected more notable improvements, especially since rivals are venturing into QHD (2K) territory or going for the newer Snapdragon 805.

In terms of design, the smartphone's outer shell shown in these new images falls in line with previous leaks. As previously mentioned, however, the Xperia Blog also obtained some images that reveal the chips and boards the handset will pack. Much of the labels have been rubbed off or blurred out, as common with such leaks. This makes it harder to identify the exact components, but we'll soon know all there is to know about the Xperia Z3 straight from the source.

Sony is also expected to unveil other devices at the IFA 2014 trade show, including an Xperia Z3 Compact and an Xperia Z3 Tablet Compact. A new smartwatch is reportedly in the cards as well, as the wearable market is on the rise. We'll keep an eye on Sony's IFA presentation and bring you the latest details, so stay tuned.
