If you use 3G on your smartphone or tablet on a regular basis, chances are that you wish for better battery life. Did you know that using Wi-fi for internet connectivity instead of the built-in 3G radio on your device is less drain on the battery?
Yes; if you turn off 3G data on your device and connect via Wi-Fi, you will get better battery times.
What You can Do
You can peg your smartphone on 2G and use GPRS/EDGE for mobile data, then connect to a WiFi hotspot wherever available – at home, on the road and at work. You can also get a personal hotspot that you can carry about.
To have your own personal hotspot, you can purchase a Mifi device. A Mifi device requires a SIM card with an active data plan and shares this with multiple devices via WiFi. Many Mifi devices in the market are able to share with a maximum of five (5) devices.
This way, you do not need separate mobile internet subscriptions for each of your devices, and you also get extended battery performance on them.
I am aware that many mobile platforms allow you to turn off mobile data. This includes: iOS, Android and Nokia Belle. If you have access to a WiFi hotspot, simply turn off mobile data. If your device also lets you choose, fix it to only GSM.
A downside of this is that Mifi devices generally have a battery life of four (4) hours if five devices are connected all through.
Hopefully, we will begin to see a greater proliferation of hotspots in our cities, especially at eateries, fast-food outlets and recreation spots.
Do you have access to a Wifi hotpot at home, at work, or at your favourite hangout? Do you use a Mifi device? Do share in the comments section below.
