iPhone battery overview: Here’s everything you need to know

Summary of information, tips and notes about iPhone battery
Just like any other smartphone, iPhone needs to be powered by a battery to function properly. In addition to their great role, batteries are also the most dangerous part of a smartphone because they are the only part that can explode in adverse conditions.

What type of battery is on the iPhone?
According to information recorded on Apple’s main website: “iPhone batteries use lithium-ion technology. Compared with previous generations of batteries, lithium-ion batteries charge faster, are more durable and have a greater energy density for longer life and reduced weight.”

Besides the above advantages, you also need to understand its disadvantages. The biggest disadvantage of Li-ion batteries is poor heat resistance, flammable and explosive. That’s why Apple has to install many battery protection features during the use cycle, and recommends users to limit both charging and use because of the potential risk of fire.

Should I replace my iPhone battery?
The answer is yes. Similar to other electronic components, batteries also have a certain use time and will gradually reduce their ability to store energy, until the maximum capacity gradually decreases (also known as battery bottles). When the battery is no longer working properly, it will not be able to supply power to the best performing components, which inadvertently reduces the iPhone’s ability to function. Worse, it can damage components.

To prevent damage to the above components, Apple has installed a power management system that, when it finds that it cannot ensure a stable current, automatically shuts down the device to protect components. This is also the cause of the iPhone crashing. It is also one of the signs that you need to replace the battery on your iPhone.

When to replace iPhone battery?
In the process of using iPhone, if during use you notice the following problems, it is a sign that your battery is having problems.

App open time is longer
Lower frame rate while scrolling
Backlight dimming (adjustable in Control Center)
Reduce speaker volume to -3dB
Frame rate drops in some apps
In the worst case, the camera flash will be disabled when displayed in the camera user interface
Apps that refresh in the background may need to be reloaded when opened

Notes when replacing iPhone battery
Know when to replace the battery:
According to Apple’s design, iPhone can operate normally when the battery has a maximum capacity of 80% of the original capacity. Your iPhone needs battery every 500 charge cycles on average.

Use different types of batteries depending on your needs:
If you have basic use needs, please replace with a new battery with the same capacity as the old battery. If you are a gamer or often use complex tasks on iPhone, you can consider using a high-capacity or super-large battery to meet your usage needs and save costs.

In addition, you should also choose genuine Apple batteries or those of 3rd parties that meet its safety standards such as Pisen, Baseus, Remax, etc. to ensure quality and safety. Absolutely do not replace floating, poor quality batteries because cheap ham has a very high risk of fire and explosion.

Choose reputable establishments
Changing batteries is an extremely complicated job, so if you are not a professional repairman, you should absolutely not do it yourself at home, but choose reputable and quality facilities to ensure safety. After replacing the battery, you should also monitor the operation of the device to see if it is stable, is there a lot of power loss or is there a phenomenon of not using the battery but still dropping?

How to extend battery life
Here are the methods to help extend battery life that Apple itself encourages users to apply:

Update the latest software
Avoid excessively high ambient temperatures (ideal temperature is between 16° and 22°C, the highest recommended is 35°C)
Eliminate elements that generate excess heat during charging (e.g. case)
Charge the battery to half capacity before long-term shutdown and place the device in a cool place below 32°C, free of moisture. If you plan to store your device for a long time, charge it every 6 months to 50% capacity.
