Turn off the wifi

Following my previous post about the Nexus One battery life I received some useful suggestions from Gia and Dan.

If the Nexus One is searching for wifi access points then as Dan pointed out, this will drain the battery quite rapidly. This is not unique to the Nexus One, I have had similar issues with the iPhone 3GS and the Nokia N95. I had hoped that the issues would have been resolved with newer phones.

It’s interesting though to see the impact of wifi and the power requirements are still an issue.

It is the constant searching that has such a hit on the battery life, if the Nexus One is connected to a wireless access point then this has a lot less of an impact on the battery. That’s the reason why when using wifi on my iPad I don’t have similar battery issues as I am connected to wifi. Likewise when using the portable wifi hotspot on the Nexus One I find that I don’t have the battery problems either. Interestingly you don’t need to have the wifi turned on to use the portable wifi hotspot, the phone will turn on the wifi transmitter when you turn on the hotspot and turn it off when you turn the hotspot off.

I did find turning off the wifi did make a big difference to battery life on the Nexus One, so it is remaining off. Apart from having to turn it back on when I am using the phone at home, it hasn’t been such a big deal and hasn’t been annoying, whereas the lack of battery life was much more annoying. Still may follow Gia’s suggestions and get a new battery and use my old one as a spare.
