I rather not sleep with the phone charging. Then during the day I would like I leave it on and probably connected to at least a WiFi connection. Arriving back home I could pop it on the charger but the thing is one wants to use it in the lounge, walking around etc .. and one wants it connected to the web to get notifications such as IM, email, social media. If the phone needs a charge in the afternoon I leave it on but I may switch WiFi off it takes at least 4hrs. That is like half a work day off.
And out of interest does the tablets take this long to charge too?
