What the Tech? Best time to charge a smartphone | What The Tech?

The big question we’ve all been asking: When is the best and worst time to charge a smartphone?

Many people do this: Plug in the phone or put it on the charger right before you go to bed. Although phones have advanced, this is still bad for your device.

As smartphones have advanced, so has the battery. Here are some things you should know about how smart batteries work:

● Memory does not develop like old batteries.

● Cold and heat affect battery life more than anything else.

● Batteries wear out over time. After two years, the flood was discovered.

Apple says its batteries will degrade by 20% within two years.

Most smartphones use lithium-ion batteries, which are better than the batteries of five years ago. And the price for the night affects the longevity.

Here’s why: The longevity of batteries is measured by their costs. Apple says its iPhone batteries last 500 cycles. Those changes don’t measure how often you charge, but how often the battery goes from 0-100%. A little confusing to some.

If you let the battery die completely, the battery will be damaged and charged to 100%, which is a single charge. If you always pay 100% and drop to 50%, the price change is half.

Some of them are like a complete price change. The math becomes more difficult to calculate if you allow the batteries to drop to different percentages.

Today’s smartphones include technology that prevents them from “overcharging,” stopping the charging process when the phone reaches 100%. Generally, it reaches 100% when the payment is finished, and the percentage drops to 99% when the payment process starts.


Battery discharge, which takes time, takes time away from that charging cycle zone. iPhones have a feature that keeps the phone from charging to 100% overnight to prevent battery damage.

iOS 13 and later learns your behavior and automatically optimizes your battery. If you fall asleep in the middle of the night, the battery will be charged. The iPhone charges up to 80% for the first few hours.

Finally the phone has a good idea of ​​when you wake up and restarts the charge a few hours before you wake up, so it’s 100%

your day begins. You can find it in the battery settings.

When I checked my phone, I saw that it charged to 80% within an hour or so after I put it on charge while sleeping. Apple learned that I wake up at 6 a.m., so between 4 a.m. and 5 a.m., the charge cycle is completed at 100%.

The idea is that this will extend battery life by reducing overall charges when I’m not using the phone.

Android phones don’t have this feature but you can turn on “battery optimization,” which closes programs you’re not using and reduces app usage that drains battery even when you’re not using it. iPads have no features.

So, good job? Charge your phone to 100% before going to bed and don’t charge it. If you have an iPhone, check your battery settings and turn on “battery optimization.”

You will find many ideas on how to extend the life of the battery, it is difficult to give a definite answer, but it is considered a theory and an accepted belief.

Of course, if you’re buying a new smartphone every couple of years, you can pay off the phone any way you like. Chances are, you won’t notice a significant difference in battery life before upgrading to your phone.
