Myth debunked: Lumia 920's super-sensitive screen drain battery.



In case you are wondering why I haven't written any posts over the weekend, well, I spent the entire weekend demolishing opposing teams in FIFA13 :)

But that's not why, there isn't much going on in the Nokia blogosphere, eveyone it seems is waiting for the release of the Lumia 920 and 820, so it has been awfully quiet.

I did come across this article about how the super-sensitive screen of the Lumia 920 would effectively drain the battery, and after reading this, it made no sense whatsoever. See, according to JDB (makers of pocketshield or whatever that is), they say the Lumia 920 would drain battery life and the thoery behind this is that
When the phone is inside a pocket or bag it can be touched by other objects. These objects can press buttons and can touch/rub the screen. This will initiate the “death loop” for who knows how much time, could be minutes or hours, depends on how active the user is since body movement will produce friction between objects/clothes and touchscreen.

There is even a nifty diagram to illustrate this:

If you read this carefully, and look at the diagram you will understand why I chose to ignore this theory (ok, let me just call it what it is... a myth).

first of all, it is true that when you press and hold the camera button even when the phone locked can wake it up, so yes if your phone's camera button is being pressed (by a pen for example), this can wake it up while in your pocket, but this has nothing to do with the super-sensitive screen. It is however important to note that you can turn off this feature by going to settings>> applications>> pictures+camera and switching the "press and hold camera button to wake up phone" feature off or there is the "prevent accidental camera launch when phone is locked" feature you can turn on too

Secondly, I don't see how Nokia would have overlooked such an obvious flaw (if indeed, they did), for example on the Nokia N9, if the proximity sensor is active you cannot double tap to unlock, so if Nokia was smart enough to implement that feature, I dont see how the Lumia 920 would have been overlooked.

I find it strange that these JDB guys came up with this theory especially since they don't have a Lumia 920 to test their theory/myth.

I am only writing about this because unfortunately Nokia has chosen to respond to this, thus giving it headline news status...

While the Lumia 920 and Lumia 820 both enjoy super sensitive touch, the firmware has been configured to avoid accidental activation of the display.  In testing this has not proven to be an issue or to cause unwanted battery drainage.
Though Nokia didn't give any specifics on how this will not occur, only stating that in testing, this hasn't proven to be an issue.
JDB's claims are based solely on myth (ok, theory), it's like claiming BMW manufactures cars without testing if the air conditioning works.

I wouldn't be writing about this if they hadn't.
