The basic version of the classic calculator is back in popular use as an app on billions of iPhones around the world, but a more powerful version is out there too, and you just have to find it.
And you can turn your virtual calculator into a scientific calculator simply by turning your device aside. But make sure that the screen orientation lock is not turned on.
The scientific calculator for the iPhone provides exponential, logarithmic, and trigonometric functions. It even has some hidden functions that reveal themselves if you press the button that reads "two".
The scientific calculator allows users to randomly generate numbers by pressing the "Rand" button on the lower right side.
And you can switch between standard and scientific calculators without losing the calculation by simply rotating your phone.
But, before we write off the basic calculator, there are still some handy hacks that make it easier to use.
For example, there is no need to hit C and start over if you make a simple typing mistake.
Instead of wiping out your accounts completely, you can simply delete the numbers individually by swiping left or right across the screen.
And you can also copy the last result without entering the application.
Alternatively, you can tap on the app from the home screen, hold it and an icon will appear with the option to copy the last shape.
Common errors drain your phone's battery!
Most of us charge our phones wrong, according to a phone repair expert who specializes in refurbishing old phones.
And the way many of us recharge our phones — including leaving them charging overnight or plugging them in while you're at work — can actually damage the battery, permanently reducing the amount of charge the device can handle.
Kewen Sharon, chief refurbishment manager at Back Market, warns in his interview with the Daily Mail that completely draining a phone's battery is also harmful.
"Leaving your phone plugged in, or letting it run out of charge, quickly reduces battery life. Instead, you should aim to keep your charge level between 20-80%," Sharon said.
And many new phones offer an option to optimize charging (so the phone doesn't take a toll on the battery).
He said, “For iPhones running iOS 13 and later, go to iPhone Settings > Battery > Battery Health & Charging, and select “Optimal Battery Charging.” This setting will automatically reduce wear on your battery, improving its lifespan. ".
Apple says the feature delays iPhone charging beyond 80%, using machine learning to learn your daily routine so that optimized battery charging is activated at the right time.
Sharon said it's a little trickier on Android, where settings can vary between different manufacturers.
He added: “By going to your Settings, then selecting Battery > Battery Usage, you can see your battery health. Then, under Manage Battery Usage, tap Optimized to help automatically extend battery life. And on Pixel phones, it can still be found under battery, but it looks a little different."
Another problem that can damage battery life over time, Sharon added, is dirt in the charging port.
“Crime and dust are the enemies of your mobile devices and battery life,” he said. “Dust builds up in your phone’s charging ports, causing your device to overheat or stop charging. Safely cleaning your phone can ensure your battery doesn’t overheat, which can lead to long-term damage.”
Sharon recommended using a toothpick and a damp cloth to clean your charging port to get rid of debris that could damage your phone.
He said, "The first thing to do before cleaning your phone is to turn off your device. Next, shine a light on your device to see how much dust you're dealing with. Use a soft, slightly damp, lint-free cloth to wipe around the charging port area. To remove debris inside the port, use a toothpick, and move it from one side to the other.”
He also warns that leaving your phone in direct sunlight can permanently damage the battery.
And if you receive warnings that your phone is overheating, this may mean that the battery is suffering long-term damage, he warns.
Sharon said, "It's best to keep your phone away from extreme temperatures. Below 0°C is very cold, while anything over 35°C is very hot, both of which can damage battery life. So, it's really important to keep Keep your phone away from direct sunlight for extended periods of time and limit its use in hot cars or trains.If the internal temperature of your device goes beyond its normal operating range, you may notice the screen dimming or turning completely black, or disabling the camera flash.You may also receive a notification It says "Charging is pending" or you get a temperature warning.
If you see a warning like this, Sharon explained, it's best to charge your phone in a cool place — and avoid charging it wirelessly.
"While charging your phone, look for a cool and humidity-free environment of less than 32 degrees Celsius (90 degrees Fahrenheit). Wired charging is also better and is preferred over wireless charging to avoid overheating," he said.
Sharon concluded, “When your phone is not charging, you can avoid overheating by reducing the brightness. If your phone has a low battery and you are searching for a signal, it may cause the device to overheat. So, if you are somewhere with a weak signal, , turn Airplane mode on, then turn it off again when you're in an area with a better connection!".
