Many people today rely as much on their smartphones as they do on their computers. So questions about how best to use smartphones, how to make them last longer on a charge, and how to protect them are common. Read on for some answers.
Q: My smartphone has Wi-Fi, but I never use it. When should I use it?
A: More phones today offer Wi-Fi connectivity, which essentially allows you to use local Wi-Fi hotspots — either public or private — to wirelessly connect to the Internet.
This service allows one to skip use of the 3G or other network provided by your cell carrier to surf the Web, send and receive e- mail, make voice over IP (VOIP) phone calls, and more. There are both advantages and disadvantages to using Wi-Fi.
First, Wi-Fi can save you money. Unless you have an unlimited data plan with your wireless carrier, you’re only allowed to send and receive a certain amount of data. Using Wi-Fi rather than your carrier’s network allows you to skirt any data cap while still being able to access the data you need.
Second, Wi-Fi access speeds may be more robust than the network connection provided by your carrier, which can translate into faster Web-enabled application performance. Third, Wi-Fi may provide you with data coverage where your wireless carrier’s network signal is weak.
Wi-Fi is, in short, another option for accessing data that may be both cheaper and more reliable than your default network.
Engaging your phone’s Wi-Fi capability may, unfortunately, result in shorter battery life, since the internal Wi-Fi chips themselves require additional power. Turning Wi-Fi off when you don’t need it should extend your phone’s battery life, which of course can be critical on the road. Accessing data over Wi-Fi may also not provide the level of security you require.
