Is it bad to leave your phone plugged in all the time

People ask a lot of questions about batteries. Is it bad to charge your phone overnight? What happens when you charge your phone more than 100%? These are legitimate concerns, but what if  your iPhone or Android smartphone is constantly charging? what about. 

Many of the concerns and questions regarding batteries are based on outdated information. Batteries may not look like they've improved much over the years, but they've actually improved quite a bit. How will this affect billing practices?

How does charging work? 

Let's talk a little bit about what actually happens when you charge your phone. Batteries convert chemical energy into electricity. 

The chemicals in the battery contain electrons, and electricity is generated when the electrons move. When you connect a battery to a power source, the electrons inside begin to move from the negative pole to the positive pole. Chemical potential energy increases. This means there is an excess of electrons, and this excess electrons charge the battery.  

When the battery is not connected to a power source, electrons move in the opposite direction, from positive to negative. Potential energy is  converted to electricity and used by the device to discharge the battery. By repeating the above cycle many times, the battery will deteriorate.

You may have heard that keeping your phone charged between 20% and 80% is good for the battery. Going from 0% to 100% is a long cycle. In general, the shorter the charge cycle, the better  the battery. 

You don't have to worry about these things because your phone actually has protection built in. For example, charging the phone to 100% will stop charging, but  charging will resume when the charge level drops to 99%. This is a short charging cycle, but it can be repeated hundreds of times while the phone is plugged in.

To combat this, iPhones and many Android devices have "adaptive" or "optimized There is a "powered" battery charging function. Instead of fully charging the battery  and charging between 99-100% all the time, it keeps the battery at about 80% and intelligently kills the last 20%, usually when the phone is unplugged. 

Can you keep your phone connected all the time? Back to the real question, can your phone charge all the time? The short answer is "probably". 

 

 There is no getting around the fact that the battery is the most volatile component in your smartphone.

Remember the Galaxy Note 7?

This disaster was due to a design flaw that allowed the battery to overheat and catch fire. However, with hundreds of millions of smartphones  manufactured in the last few decades, battery explosions are extremely rare.  

Adaptive and optimized battery charging are just a few of the  battery-saving features for consumers. A myriad of  safety measures and comprehensive safety checks are performed internally before the device  leaves the factory.

Leaving your phone plugged in all the time will drain the battery completely and charge time will gradually decrease, just like leaving your laptop plugged in all the time. You can check this by checking the status of But does battery life really matter when it comes to keeping your phone plugged in all the time? 

Theory

In theory it's fine to leave the phone connected all the time, but "always" is very liberating. The more the battery deteriorates, the more likely something bad will happen. If you  need to keep your phone connected.
