Welcome to this week’s edition of Android Q&A! As always, we try to answer as many of your great questions as possible. This week, we talk about the upcoming mobile device SoCs, the Tegra K1 and the Snapdragon 805, devices that support USB on-the-go, and more. Let’s get started!


Question 1

Which of the new SoCs for mobile do you like most? What is really most important – CPU or GPU? – Vegard Loknes

Answer

NVIDIA Tegra K1 Benchmarks Specs-12

There was a lot of buzz following the announcement of the Nvidia Tegra K1, with initial benchmark tests run by Tom’s Hardware on a device running the Tegra K1, the Lenovo ThinkVision 28, showing the processor outperforming any of its competition. Qualcomm hit back at the validity of these test results, stating that while the Tegra K1 is made for mobile devices, using it with a larger device may have skewed the results. Qualcomm also showcased video demos of the Snapdragon 805 and Adreno 420 GPU in action, which were very impressive. It’s important to note that at this point, neither of the two SoCs have been tested at scale, in a real world environment. While both are definitely a step up from their predecessors, with a big emphasis on graphics, a proper comparison, and the more accurate answer to which is better, will only be possible once both are available in the next generation of smartphones and tablets.


Question 2

Can you tell me whether the Nexus 4, Nexus 5, Moto X, or Moto G support USB OTG? How can I found out? – Jagadish Naidu

Answer

You can find a comprehensive list of all devices that support USB OTG here.


Question 3

What’s the difference between a Lithium Ion battery and a Lithium Polymer battery of the same capacity? Marquise Washington

Answer

The development of Lithium-Ion batteries began in 1912, but did not become popular until they were adopted by Sony in 1991. Li-ion batteries have high energy-densities, and also cost less tha li-polymer batteries. In addition, they do not require priming when first used, and have a low self-discharge. However, lithium-ion batteries do suffer from aging, even when not in use.

Lithium-polymer battery can result in credit card thin designs while still offering relatively good battery life. Lithium-polymer batteries are also very lightweight and have improved safety. However, these batteries will cost more to manufacture and have a worse energy density than lithium-ion batteries.

Question 4

How to change the app drawer view to a list view (like WP) instead of the grid view? – Calvin Nobel

Answer

To change your app drawer to a list view, you can download the app called AppDrawer (MIUI App Drawer), which is available on the Google Play Store here.

    Great article, many thanks for the comparison of the two super chips. Also under the battery question, I don’t think it should read “The development of Lithium-Ion batteries began in 1912, but did not become popular until they were adopted by Sony in 1191″
    Should it be 1991?

      Sony’s been in business for quite a while.

    Nothing comprehensive in that list, regarding Q#2. Also the list looks a little outdated. Not very helpful to the original question either. I can tell for sure that Nexus 4 and Nexus 7 (2013) do support OTG – neither of them are in the list. Not out of the box, but with a little help of StickMount: https://play.google.com/store/apps/details?id=eu.chainfire.stickmount – root required.
