So let's spend some time talking about what burns power on your Smartphone. Hopefully this will give you an understanding of where that battery power went and maybe help you figure out how to squeeze a little more life out of your devices. ... Every phone is different. Any numbers I give for a "typical" phone might be wildly different on your phone. Hardware changes all the time, and so do these numbers. So don't hold me to them. But, a "typical" WM Smartphone has around a 1000 mAh battery. And, when in standby (backlight off, screen off, cpu doing very little, phone only listening for incoming calls), the typical device burns around 5 mA. Doing the math, you'll see that the typical device should run for 200 hours on standby."</i><br /><br /> <img src="http://www.smartphonethoughts.com/images/Battery.jpg" alt="User submitted image" title="User submitted image"/> <br /><br />Mike Calligaro over at the Windows Mobile Team Blog has written another informative article, this time it's about the power consumption on our Smartphones. Mike is talking about the factors that can decrease the battery life by increasing the power consumption. I didn't know that those blinking LEDs can affect the battery life, in fact I am one of those people who misses them if the phone doesn't have them, like the Moto Q for example. After reading the article I am ready to carry the <i>"Down with LEDs"</i> placards; anyone wants to join me? :lol:

I hate blinking lights on phones. I used to own a Sony Ericsson T68i about 4 years ago that had a separate LED for power on and bluetooth. When you were in bed, trying to get to sleep, it was like a bloody disco!

I don't really see the point of them anyway. I know that my phone and bluetooth are on, I don't need a flashing LED to tell me. Gah!

Bluetooth LED, I totally agree, is a waste of power. The signal indicator is useful because after the screen blanks out it tells me that the phone still has signal. At my work place the phone loses connectivity even in places where it had signal, not to forget the recent "Searching..." issue with the 2125.

But I agree about the problem at night time, I always keep the phone face down on the night stand, even then a lot of light manages to sneak through, but at least it does not light up my ceiling. :-)

Oh wow! great article. That really breaks things down for you. The real way to save power is to make sure those 3rd party applications don't waste any more than they need to and to keep that backlight off. I'm going to turn my setting down a little more now. :D

I like the blinking lights. I want more! That battery in the picture is the extended battery for the Q.

Wow, you really know batteries. 8O Yes, it is the extended battery for Q.

I was gonna gloat over that for a bit but the truth is I have one. That's how I know. :oops:

The antenna LED should be off when there is a signal present, since that is the usual state, and blink when there is no signal.

That's a good point. In general do enjoy blinking lights though. :mrgreen:
