Talk, Rumors, X Versus Y "I am truly shocked that so many people are being duped by BlackBerry's recent announcement of their tablet, the PlayBook. I have read endless comments from people who are saying they can't wait to get this tablet computer. Well, I think I have some bad news for you folks. There is no evidence that the PlayBook exist as advertised. Why do I say this? I will make it brief..."

iOS != QNX. iOS != Symbian, for that matter, as far as battery life is concerned.

No, but a screen is a screen. A power-hungry processor is a power-hungry processor. QNX doesn't magically reduce the power requirements for either.

Especially if they plan to run Flash Player on top of it ;)

Power hungry? When the A9 runs at 1.6ghz it uses an average tdp of 2 watts.

It also has 1080p video decoding built into the die.

We don't know how efficient their software stack will be but given that QNX is streamlined for embedded use I'm going to bet on pretty damn efficient.

True, but the operating system can go very far in determining battery life. My Android phone, the Motorola Cliq, has a friggin' huge battery but barely makes it through a day of light browsing once or twice an hour, and a couple of phone calls and texts. Why? It has a low power, efficient processor, and an energy efficient screen so those aren't the culprits. The cell and WiFi radios are no different than any other Motorola smartphone when it comes to power draw, so it's not them either.

No, I'll tell you why: Because it's running the older, less efficient version 1.5 of the OS, and the MotoBlur UI that runs on top of the OS is constantly polling data, even when you set the phone in "Battery Saver" mode. This device is a clear case of the software, not the hardware, running the battery down. I'm looking forward to the 2.1 update mostly for the gain in battery life.
