Blue light from smartphones might be interfering with your sleep, but there’s no evidence that it’s blinding you, despite ad claims and, occasionally, headlines implying it is.

If you're all about that prepaid life, but also like using data for all the things, this may be a plan for you.

With everyone from local scammers to government agencies trying to get hands on your data, there's never been a better time to beef up your privacy game. Fortunately, there are a ton of options out there to keep your messages, files and phone safe on Android.

A study published this week leaves none of us surprised: Screen-addicted teens are unhappy. The lead author is Jean M. Twenge, the professor of psychology who wrote The Atlantic piece "Have Smartphones Destroyed a Generation?" (In a nutshell, maybe, but it's a hopeful sign that teens themselves are beginning to link their mental health troubles to their always-buzzing devices.)

What Twenge and her team at San Diego State University found in their new research is that the happiest teenagers used digital media for less than an hour per day. They spent their time doing other things instead - playing sports, reading newspapers (really?) and engaging in good old-fashioned face-to-face interaction.

While hiding your number may not be the best idea if you actually want people to pick up your call, you may have a legitimate reason for wanting to hide your number from coming up on the receiver's phone. Here's how you can do it.

Years after it first appeared, wireless charging has finally arrived on the iPhone -- but what is this magical charging method that's been on other big phones for a couple of years now? And is it really all that superior to just plugging your phone into the wall every night? Here's what you need to know about wireless charging, and the kit you need to make it work.

Many of us use our smartphones and tablets to stream videos and movies, but not before we plug them in to make sure there's enough battery life to last the viewing session. But cradling your device for hours at a time can get uncomfortable, especially when you've got a charging cable poking out of it. That's where this Podium-Style Charging Stand comes in handy, and it's on sale for nearly 80 percent off.

The future is wireless — as far as phone charging is concerned. You may expect to shell out a pretty penny to stay on the cutting edge of today's charging tech, but with the Mini Qi Wireless Charging Pad going for 70 percent off, you can do so without breaking the bank.

Perhaps you have a meticulously organised Notes app, a framed poster of all your favourite recipe cards, or a mind like a steel trap that stores your go-to cooking ratios down to the teaspoon. Must be nice!

When you hand someone your phone to show them a picture, you should be able to trust them not to go swiping through your camera roll. But we live in a fallen world. And the worst violators of phone-borrowing etiquette are older relatives and in-laws -- the same people who'd be most horrified to see your nudes or, so much worse, your 20 selfie outtakes.

We asked for readers' most bizarre, awkward wrong number calls and text messages and, boy, did they deliver. These tales of "whoa" involve everything from clueless callers to tactless texters, playful responses to toilet phones, and everything in between.

Even with smartphones and caller ID, wrong number calls and texts still happen all the time. What's the most bizarre one you've ever received? And how did you handle it?

We spend a lot of time on our phones - so it makes sense if our batteries usually hit that dreaded 10 percent mark before the day's even half over. That's why it's important to stock up on chargers whenever you can, and now you can re-up on three extra-long Lightning charging cables for a fraction of the cost.

Most of us breeze past the terms and conditions that come with free Wi-Fi networks and just hit "yes" so we can get online. When you sign into a shopping centre's Wi-Fi, though, you might be agreeing to allow them to track you.

When you're buying a new gadget, you want the fastest, most powerful one you can get for your money. Benchmarks can help you figure out what devices have the most power, but sometimes they're just a distraction.

If talking to people on the phone gives you anxiety, or you tense up every time your phone rings, here are a couple things psychologists recommend you try.

Budget telco provider Vaya has just announced one of the best postpaid mobile deals we've seen in a long while. its Unlimited XL plan now comes with 9GB of data for just $36 a month.
