iPhone battery worn out: Signs and What To Do

The iPhone battery is a fundamental component for your device's performance, from models like the iPhone X to the very latest iPhone 17 Pro Max. Over time, it's normal for the battery to lose capacity, but when it's "tired," it can start presenting problems that hinder the user experience. Recognizing the signs of a tired battery is essential to act in time and avoid unexpected breakdowns.

At iServices, mobile phone repair specialists, we know that many users are concerned about their iPhone's battery life and performance. Fortunately, there are several solutions that can help restore or replace the battery, ensuring your device works like new again. In this article, we explain the most common causes of battery degradation, possible solutions, and answer the most frequent questions.

Causes of iPhone Battery Degradation

Excessive Use and Charge Cycles

Each iPhone battery has a limited number of full charge cycles, typically around 500 cycles for recent models. A charge cycle corresponds to 100% capacity usage, whether in a single charge or multiple partial charges added together. After many cycles, the battery begins to degrade, losing capacity and battery life.

Inadequate Charging

Using non-certified chargers or charging the iPhone with damaged cables can cause overheating and damage the battery. Furthermore, leaving the phone constantly plugged into the charger, even when charged to 100%, can accelerate battery wear.

Extreme Temperatures

Exposing the iPhone to very high or very low temperatures negatively affects the battery. Excessive heat can cause swelling and loss of capacity, while intense cold temporarily reduces battery life and can lead to unexpected shutdowns.

Manufacturing or Software Defects

Sometimes, manufacturing problems or failures in operating system updates can lead to incorrect battery status readings or excessive power consumption. In these cases, the phone may show signs of a tired battery even with little use.

How do I know if my iPhone battery is tired?

You can check the battery status in the iPhone settings, under "Battery" > "Battery Health". If the maximum capacity is below 80% or if the device experiences unexpected shutdowns and reduced battery life, it is likely that the battery is tired.

How long does an iPhone battery last?

Normally, the battery maintains good performance for up to about 500 charge cycles, which is equivalent to approximately 1 to 2 years of normal use. After this period, the capacity begins to decrease, and battery replacement may be necessary.

Can I replace the iPhone battery at home?

While there are kits to replace batteries, this operation is complex and can damage the device if not performed by professionals. At iServices, we guarantee a safe replacement with original parts, thus preserving your iPhone's warranty.
