The Fastest Phone of 2017 (Surprising Results) (Video)

Doing a quick series of experiments here on the channel. I wanted to put all of the best phones of 2017 up against one another in a series of scientific not really that scientific challenges. Today, we’re going to start with speed. For this experiment, I put each device, on the same wifi network, installed the same popular apps and games that will, in this case, represent normal use, closed all of their open apps, and then saw how long it would take each one to load each app in a side by side. I chose the phones I figured […]

Huawei Watch 2

Huawei Watch 2 (Complete Walkthrough) (Video)

I was a huge fan of the first Huawei Watch. It had Android Wear, was well-built, and looked like a normal watch so when Huawei reached out and asked me to check out their latest version the Huawei Watch 2, I said absolutely. Now, after spending a little time with it, I figured I’d do a complete walkthrough of the Huawei Watch 2 Classic for anyone interested in the device and all the things it is capable of doing. First up, the watch itself is larger than the original Huawei Watch, in fact, it’s pretty hefty, but along with that

How to Check if Apple is Slowing Down Your iPhone (& What to Do About It)

Welp, Apple recently admitted to slowing down users’ iPhone processor speeds when iOS detects that the device has a battery that is suffering. Along with this admission after the outrage from people calling Apple out for deliberately slowing down their iPhones to get them to upgrade to new ones, Apple also announced that if you have a phone with an affected battery you can go to an Apple store and get the battery replaced to bring the performance back for $30 instead of the usual $80 during 2018. Without getting too much into why this was super not okay of

Charging Myths

Does Wifi, Airplane Mode, & Screen On Affect Charging Times? (Surprising Results) (Video)

I did a video recently where I compared the new faster charger solution for the iPhone 8 Plus to the iPad charger and when I did it I didn’t think to turn off the Wifi on one device so one had it and one didn’t and you guys pointed it out. Now, I didn’t think of it because I assumed it wouldn’t make much of a difference. But with how many of you guys call it out, it got me wondering. And we know what happens when I wonder… So I set up the iPhone 8 Plus and charged it

Gigabit LTE Speedtest

What is Gigabit LTE and Why You Need It (Video)

Guys, we need to talk about a feature in phones that no one seems to be talking about: Gigabit LTE. Now, as the name implies, it’s LTE that is capable of delivering up to 1Gb/s speeds. I managed to, in San Francisco in the real world, not a lab get over 400mbps. Let me explain. Allied Content: This Video was Sponsored by Qualcomm (but it is something I thought was interesting to talk about or I wouldn’t have done the video 🙂 Hope you enjoy it!) How it works essentially is there are 4 LTE technologies that Qualcomm has managed

Snapdragon 845 Macro

Why You Should Be Excited About the Snapdragon 845 (Video)

I’m here in Hawaii for Qualcomm’s tech summit and if you’ve maybe heard they’ve just announced their successor to the super popular Snapdragon 835, the new 845 and frankly, while it might be hard to get super into a piece of silicon without being able to see what it’ll do in a device, I’m kind of excited about it. The list of features on this thing are pretty impressive and there are a few standouts that I think we should discuss. Firstly, and of course, something I’m particularly excited about considering my line of work is the capturing capabilities. This

Best All-in-One

Best All-in-One PC for the Money (Video)

First, let’s quickly talk about why you’d want an All-in-One in the first place. The biggest reason is the screen size for the money. Most all-in-ones come with 23″ or higher (and sometimes much higher like the 34″ curved model from HP). A smaller sized screen laptop or desktop computer plus a separate monitor of that size would cost a decent amount more than an all-in-one usually. Besides that, newer ones save a lot of space and are even starting to look pretty darn sleek, too. So if you tend to sit in one place to use the computer (or

Touch ID vs Face ID

Face ID vs Touch ID: Which is Faster?

It’s the big debate, isn’t it? With the new iPhone X completely removing the home button and fingerprint sensor in favor of a facial recognition system instead, people are up in arms about TouchID vs FaceID. I’ve been using FaceID for a bit now, and even tested it with my buddy E from BooredAtWork, and I have to admit it works pretty well. But, it got me wondering, how does it actually compare to TouchID in terms of speed? So I’m going to test all the scenarios that use either security feature and let’s see which works faster TouchID on

OnePlus 5T vs OnePlus 5: What’s Actually Different? (Video)

OnePlus just announced their latest flagship the OnePlus 5T just 5 months after the OnePlus 5. The big questions for most people then are what are the actual differences between the 5 and 5T? Is it worth getting the OnePlus 5T over the 5? Etc. At the event for the new device recently, I asked around to confirm exactly what the differences are. Here’s what I found. What do you guys think? Is anyone mad about the 5T so quickly after the 5 coming out? Let me know!

Best Rugged Phone Under $300 (Video)

I did a video a while back on the Cat S60. An android phone created with the adventurous in mind (I even ended up taking it to a certain festival in the middle of the Nevada desert to test it out). It was a great phone actually, but the price for it is about $861. So what if you just need a rugged phone but don’t want to empty the piggy bank to buy it. Maybe even be able to keep your normal, more fragile smartphone, and buy another rugged phone to just swap to when you get the urge

Best Sounding Truly Wireless Headphones (Video)

Bose is a name in the audio world that I’m sure I don’t need to introduce. They’ve been around forever and chances are some audiophile you know has at least one pair, even if they’re just the noise canceling ones that you see on every single flight. Thing is they’ve made a ton of wired and wireless headphones, but they’ve never made a truly wireless pair of headphones. Until now. These are the Bose SoundSport Free.   Now, I’ve used plenty of other truly wireless headphones over the last year or two, from the oh-so-popular Air Pods to the IconX’s
