6 facts about smartphone batteries you may not know

6 things you may not know about phone batteries

Phone batteries have been optimally developed

You may not know, phone batteries or other mobile devices all use Lithium-ion (li-ion) batteries. Battery technology has not made any significant progress in the past decade. Technology manufacturers only focus on extending phone battery capacity and saving energy, helping to extend usage time, efficient charging and discharging management software…

You also shouldn’t expect a new type of battery, that’s a story for the future, but for now, we only focus on solutions to help the battery work better. The usage time and lifespan of phone batteries depend on usage habits and the handling of hardware and software. Manufacturers focus on integrating larger capacity batteries.

Fast charging does not affect the battery

The regular chargers that come with the device will have a power range of about 5W to 10W. However, with the outstanding development of technology today, companies continuously launch fast chargers with power up to 25W, or even 45W, helping to shorten charging time.

There are many rumors that using fast charging will affect the battery, making it prone to battery swelling, so what is the truth? Fast charging does not harm the battery, only when your battery is damaged due to technical errors or the charger is short-circuited.

According to experts, the fast charging process includes 2 stages, in the first stage, the voltage is pushed to the highest level to charge the battery from 0 to about 50-70% in the fastest time, during this stage, the battery can absorb energy quickly without affecting the phone battery.

In the next stage, when the battery reaches 50% or more, the fast charger will automatically slow down, the charging speed will significantly decrease to avoid causing adverse effects on the battery.

No need to worry about overcharging the phone battery

Have you ever thought that continuing to charge the phone when the battery has reached 100% will reduce the battery’s lifespan and easily cause damage or explosion?

However, nowadays most new smartphone models are equipped with automatic shut-off technology when the battery is fully charged.

But in reality, during usage, issues may arise that you are not aware of, to ensure, you can charge up to 90% and then unplug. For some iPhone devices equipped with internal charging features, the charging process will end when the phone reaches a battery level of 80%. If you are someone who has a habit of charging your phone overnight, you can try enabling the battery optimization feature to monitor the charging schedule while keeping the iPhone battery always at 80%.

High temperatures can damage your smartphone battery

High temperatures are the main factor you must avoid if you want to extend the lifespan of your phone battery, especially in severe cases, an overheated battery can easily lead to explosions.

According to some studies, if the temperature reaches 86 degrees F (30 degrees C), it will reduce the battery’s efficiency, so try to keep your device away from high-temperature places such as direct sunlight, car dashboard areas,…

Shouldn’t let the battery run out?

Although smartphones today are equipped with advanced technologies, the issue of using up the battery until it shuts down and then charging will not significantly affect the battery’s quality. Because current technologies allow the device to shut down when below 1-2%.

However, according to the advice of some experts, if not in a special case, you should not use the phone until it shuts down and then charge it, plug it in when the device is below 30%.

Mismatched chargers and cables will not affect the battery

Unless the charger and cable you are using are defective or faulty, combining any charger and cable will not have any impact on the phone battery’s lifespan, although the charging time may be somewhat affected.

Manufacturers strictly adhere to industry standard rules for fast charging and allow you to effectively fast charge with various compatible cables and chargers.

Effective ways to save battery

To save more phone battery, users can employ some tricks or tech tips to conserve battery.

Some methods include reducing screen brightness, turning off Wifi and Bluetooth when not needed, limiting background data usage through settings, monitoring apps using GPS, reducing screen timeout, etc.

But the truth is, no matter how carefully we maintain it, the phone battery will still degrade over time. Hopefully, this article has provided you with useful information, and if you have any questions, you can directly leave them in the comments section for answers.
