iPhone battery charging

One of the biggest concerns of iPhone users is having inadequate battery life. It’s no wonder people are asking, can iPhone battery be 100%? In this article, we’ll answer that question and explore the nature of iPhone batteries.

Understanding iPhone Battery Life

The life of an iPhone battery is determined by how often it is charged and discharged. By charging your iPhone frequently, the battery’s performance and lifespan will decrease, causing it to drain faster than usual. To maximize your battery performance, you should charge your iPhone only when it needs it.

Typically, iPhones come with lithium-ion batteries, which are designed to function optimally when between 20% to 80% charged. Keeping the battery within this range is important to ensure that it lasts for a long time. Going above 80% won’t cause any immediate damage, but it will shorten the lifespan of the battery in the long run.

Can iPhone Battery Be 100%?

Technically, an iPhone battery can be charged to 100%. However, it is not recommended to do so as it can cause damage to the battery in the long run. Charging your battery up to 100% repeatedly, especially when it’s not necessary, can lead to battery deterioration and a shorter lifespan.

Moreover, charging the battery beyond 80% does not provide significant benefits in terms of battery life. Instead, it may only provide a small increase in usage time before the battery is drained again.

What To Do To Maximize Your Battery Life?

Now that we know that charging the iPhone battery up to 100% isn’t ideal for its longevity, the question arises: what can we do to maximize battery life?

Here are some tips to keep your iPhone battery in excellent condition:

Tips Benefits
Charge your iPhone frequently but don’t let it drain completely. It preserves the battery’s life and lifespan.
Avoid exposing your iPhone to extreme temperatures. Extreme temperatures can damage the battery.
Turn off features like Bluetooth, Wi-Fi, and GPS when not in use. These features use a lot of battery power and drain it quickly.
Use a high-quality charger and cable. Low-quality chargers and cables can damage the battery.


Charging your iPhone battery up to 100% won’t harm your device immediately, but it can cause long-term damage. Instead, it’s better to keep your iPhone battery within the range of 20% to 80% to ensure its longevity. Follow the tips mentioned above to extend the battery life of your iPhone and enjoy its features for a longer time.
