The iOS 16 update for iPhone has many new and exciting options, most of which improve the user experience overall. Some of the features and changes fix frustrating issues from iOS 15 and older, and some of those "fixes" can seem annoying if you're used to doing things a certain way.

With Apple releasing the iPhone XR, it appears Samsung is looking to challenge this "budget flagship" option head-on. They brought their usual two phone releases this year, but also threw in another three for a total of five phones, including the Samsung Galaxy S10e. And for many, this might be the option to look at.
With this year's iPhones, Apple built upon the success of the iPhone X in a somewhat iterative manner. All three phones borrow from the 2017 flagship's design, which many praised as being the best in years. They also tried to help those of us who don't have more than a grand to spend on phones, creating a new product with a few compromises.
Every once in a while, we find ourselves in a predicament where we need an inexpensive smartphone.

That's where Android One comes in.
The Huawei Nexus 6P was released a little over a year ago, but despite doing moderately well in sales, the device has had more than its fair share of issues. When first released, there were numerous reception and memory management difficulties that left users extremely frustrated, though, those problems were solved with updates pushed by Google.
Several major web services—most notably Facebook—have horrendous Android apps that occupy way too much space and drain battery life at an alarming rate. Such issues have led to a new trend where third-party developers create minimalist "lite" apps that are essentially the mobile website bundled into a native Android wrapper, freeing up storage space and saving battery life without sacrificing many features at all.
The vast majority of Android apps use background services to sync data, check for location updates, and perform various silent tasks. These background services can start up whenever they'd like, and they continue to run in the background even when you're not actively using the app that they originated from.
Greenify is a terrific app that allows you to put battery-hogging apps into "hibernation." Effectively closing the problematic apps and preventing them from running until you explicitly launch one of them, hibernation is a great way to save battery life while you're not using your phone.
Quick video that will show you how to close applications that are running in the background on your Apple iPhone 5C. This will help to save your battery life.

For this project, I was inspired by the as-yet-to-be-released movie called The Prototype when making this mask. Paper strips and a mix of water and flour is the main things you'll need to make this Prototype-like mask. For the eyes, I used old halogen bulbs and inside them I put LEDs connected to a battery with switch.
We've all been there. Your phone's either dead or barely hanging on with a few minutes of life left, and you only have a small window of time to charge it before you need to head out. Sure, you can charge it for the few minutes you have, but what's the point if your device is going to die again in several minutes?
What's a penny worth these days? Not much. But could there be some free energy hidden inside your spare pennies? You'd be surprised! See how I hack together stacks of pennies into makeshift batteries that can drive small-current devices like LEDs and calculators.

K'NEX is one of the most popular construction toys on the market, right next to Lincoln Logs and LEGOs, but what makes K'NEX stand out is the fact that children can build mechanically derived toys. Instead of blocks or little logs, kids use interconnecting plastic rods and connectors, which give them tons of contraptions to build and play with. Today, K NEX has even more possibilities with wheels, pulleys, panels and flexi-rods to make amusement park roller coasters, airplanes, animals, bikes...
When the first iPhone with Face ID came out, Apple removed a popular feature — the status bar's battery percentage indicator — because of how much space the TrueDepth camera system's notch took. It's been absent on all Face ID models since. Now, almost five years later, it's finally made a comeback.
