At the IFA trade show in the beginning of next month, Samsung Electronics and Motorola Mobility plan to show their new smartwatches, Sony will try to convince that remains competitive in the smartphone market and LG will demonstrate its expertise the fruits of its investments in OLED TVs. Samsung has revealed plans to launch the round Gear S2 in Berlin. This model is likely to use the Tizen operating system and be smaller and better-looking than the original model. If Samsung wants to keep the cost down and improve the battery life, removing the integrated 3G connection would also be a step in the right direction.

Samsung sold 600,000 wearables to gain a 3.3 percent market share, according to IDC. That left it far behind Fitbit and Apple, which sold 4.4 million and 3.6 million units, respectively.

Motorola Mobility sold only 150,000 smartwatches during Q2, IDC said. The round, Android Wear-based Moto 360 was one of the most anticipated products when it arrived last year, but it sales were weak. At IFA, the company is expected to launch at least two new and improved smartwatches with different sized screens.

Samsung has already put its contenders on the field with the recently launched Galaxy Note 5 and Galaxy S6 edge+, but it looks like there will still be some smartphone introductions at IFA.

Huawei Technologies is expected to launch a successor to the Mate 7. The new model is rumored to be called the Mate S and comes with a 6-inch, 1440 by 2560 pixel screen. It may also have a 21-megapixel camera, up to 64GB of integrated storage and 4GB of RAM.

That debut will go up against the anticipated Xperia Z5 from Sony, which will carry an impressive 23-megapixel image sensor. The company will also deliver a long battery life with a 4,500mAh battery capacity, according to reports. The Z5 is also rumored to be one of the first devices powered by Qualcomm's Snapdragon 820.

New TVs have always been a mainstay at the show.

LG Electronics has already said the company will unveil four new OLED TVs in Berlin. The 55-inch and 65-inch EF9500 models feature the industry’s first flat 4K resolution OLED displays, according to LG. They also have support for HDR (high dynamic range).

LG promotes its OLED panels, which can deliver the absolute black that makes the bright colors of HDR look even more impressive.
