Now, there are 3 different modes for the Wifi suspension control:

- Never: This option never turn off the wifi connection. So, is better when you are connected to a wifi, but is worse when you are not, because the phone is always searching for connection.

- When it´s not charging: This option turns off the wifi when you turn off the screen, if the phone is not charging, so, is basically like the next option if the phone is not charging, and the first option if the phone is charging.

- Always: This option turn off the wifi always when you turn off the screen. So, is better when you are not connected to a wifi, because the phone isn´t draining battery searching for wifi. But it is worse when you are in a known wifi zone, because the phone is using the data instead the wifi when the screen is off, which drains more battery and waste data of your mobile monthly data.

Neglecting the option of turning wifi on/off manually thorugh the widget, and not using 3rd party apps like juicedefender, I thing the most intelligent and battery saver option depends on your life. So there isn´t a good option for all the people and for all days. For example, I thing the best option for me in the working days is 'Always', because I doesn´t have wifi in my working place, and I spend 10 hours a day on it, so, when I am working, the phone is in my pocket without searching for wifi, but, in the weekend, the best option for me is 'Never', because I spend a lot of time on my house. Finally, for a person who stays the most time of his day in a wifi zone, the best option is 'Never'.

Ok, now I ask, it could be an option that could be the best for all the people? I think the answer is YES:

I think if could be possible to have a mix of 'Never' and 'Always'. I explain, imagine the wifi is suspended at this moment, so you are on mobile data, and you are in your house, for example, and turn on the screen to view the weather. When you turn on the screen, the wifi awakes and connect to your home´s wifi connecion and you view the weather. Now you turn off the screen, BUT, THIS IS THE DIFFERENCE whith the 'Always' option, the wifi DOESN´T turns off, because it is connected at this moment. So, all the time you are at home, since the first screen´s turn on, the phone is connected to the wifi, saving mobile data, and battery, because the wifi drains less battery. Now, you leave your home, and, when the phone lost the wifi signal, turns the wifi off, so, when you are in a not known wifi zone (like the street), the wifi suspends itself for saving battery of wifi searching. The wifi only will search for a known wifi when the screen is on (like now with the 'Always' option) and, if it isn´t connected to a wifi when you turn off the screen, the wifi goes to suspension mode. Now you enter to your home again, with the phone in your pocket, with the screen off, so the phone won´t connect to your home wifi until you turn on the screen, and at this moment, your phone will always be connected to your home wifi until you leave your home again.

I think that is a good idea, and I guess why google doesn´t include something like this in android, it could be the best option for all people in all the situations.

What do you thing about the idea?
