Sometimes it feels like technology advances faster than most of us can keep up with. That’s how outdated tech advice can become gospel. That's why it’s good to stop and reevaluate your assumptions every now and then. It's also why we strive to keep you informed with the truth, so you won't waste time or money on things that don't work.

We've rounded up common tech myths about battery charging and overall computer maintenance (click here if you missed our article "7 tech myths you believe that you shouldn't"), but in this article we're taking a broader look at the digital age, including cellular service, robocalls, malware, browsing and even what to look for in a tablet. Check out these five big myths that don’t hold true.

1. More bars = better service

You’re having trouble keeping a cellphone call connected. You check your phone and you see plenty of bars. What is going on here? Why are you still having trouble? It’s because those little signal-strength bars don’t necessarily mean what you think they do.

Signal bars are meant to indicate how strong the connection is between your phone and the cell tower, but there’s no industry standard that dictates how those bars are calculated. It’s up to the phone manufacturer to decide how to handle it. That means two different phones connected from the same spot to the same tower might show different numbers of bars. There can also be variations in the signal based on which carrier you use and its choice of network technology.

Let’s go back to that original problem. Your phone has plenty of bars, but you’re still not able to keep a connection. This underlying issue might be network congestion, which can happen in urban areas and during big events when a lot of people are all trying to use the network at the same time. While the number of bars is usually a good indicator of the signal, it’s not foolproof.

2. You should block robocalls

Robocalls are a modern plague on our phone lines. These unsolicited sales and scam calls seem to be getting more frequent and bolder. When you receive one, your first instinct is probably to block the caller. That might make you feel better in the moment, but it won’t really stem the tide of robocalls.

Some robocalls “spoof” numbers, which makes it seem like a call is coming from your area code. It may even share the first three digits of your own phone number as well. Blocking those fake numbers won’t get you anywhere.

Your best options are still to sign up on the Do Not Call Registry, report unwanted calls to the FTC or FCC, or try out an anti-robocall app, like Nomorobo, that will help weed out scams and telemarketers.
