Kobe Bryant went on the Lakers' disabled list due to a painful Achilles tendon tear, but before the NBA star's season-ending injury, he was able to hawk the new Lenovo P780.

The Lenovo P780 is described as "a new style smartphone" by Bryant in a behind-the-scenes almost phone-less ad. It shows the basketball player holding the China-bound device at the very end.

The one-minute video doesn't get into the official Lenovo P780 specs either, but the it will have a 5-inch display, 8MP camera, and 4,000 mAh battery, according to Engadget and GizChina.

That should make for Bryant-style battery stamina at full health.

The WCDMA device is also said to be 9.9mm thick and boast a sensitive touch screen that allows gloves and non-capacitive styluses to be used.

Lenovo P780 vs P770

The Lenovo P780's battery life and camera solution are have certainly been upgraded over the P770 model.

Last year's Android smartphone by the Chinese company had a smaller 3,500mAh battery, a 5MP camera, and a dual-core 1.2 GHz Cortex-A9.

There's no official word on the P780 CPU, but in all likelihood it will have a quad-core MediaTek chipset and 1GB of RAM, according to the latest rumors.

Lenovo is said to be launching the new smartphone in China later this month, but the Beijing company hasn't announced plans to release this dual-SIM device outside of its home territory.

Bryant may be one of the few Americans to play around with the Lenovo P780 if that remains the case.

Exynos-based Samsung Galaxy S4 Not Fully Power Efficient, Says Developer

Samsung’s latest and greatest smartphone, the Galaxy S4, is currently available in two versions, one with a quad-core Qualcomm Snapdragon 600 processor and another with the South Korean company’s own Exynos 5 Octa with 4 Cortex-A15 cores and 4 Cortex-A7 cores. With the Exynos 5 Octa, Samsung promises energy efficiency by switching between battery-saving Cortex-A7 and the high-performance Cortex-A15 cores. But it appears like the S4 is not using the best possible way to do the shifting.

You can see how things work with the Octa below.

The image that you see below shows how the cores should be working.

According to Developer AndreiLux, the Galaxy S4 currently switches all 4 cores between the two processors like a cluster rather than using core-pair shifting. The device appears to have arrived with lower level firmware.

AndreiLux says:

Basically there are three modes of operation of big.LITTLE:

Cluster migration: When load rises, just like when a phone increases its frequency per DVFS, all the cores will jump from the LITTLE processor to the big one. You either have 4 A7 cores or 4 A15 cores online.

Core migration: When load rises, it will only jump those cores from the LITTLE processor whose load exceeds the capacity of the A7 cores: You can have a single A15 online with 3 A7′s on. Or any other combination of a total of 4 processors.

HMP (Heterogeneous Multi-Processing): This is a vastly more complex working mechanism, and its implementation is also an order of magnitude more sophisticated. It requires the kernel scheduler to actually be aware of the differentiation of between the A7 and A15 cores. Currently, the Linux kernel is not capable of doing this and treats all CPUs as equals. This is a problem since we do not want to use the A15 cores when a task can simply be processed on an A7 core with a much lower power cost”.

So when the A15 cores are activated, the battery will be killed faster. This might explain why some people are experiencing heating and battery drain problems with their S4s. But hopefully Samsung will release a software fix soon that could make the S4 more power efficient.

What are your thoughts about all this? Do you have plans to buy the S4? If you are using the device now, are you having power issues?
