The iPhone battery is the beating heart of the device, as you depend on it to perform daily tasks, from calls and browsing the Internet to games and running heavy applications.

But over time, the battery starts to lose its ability to hold a charge, which raises the question that every user asks: When should I change my iPhone battery? This is a crucial moment in the life of your device, as a deteriorating battery can significantly affect the performance of your iPhone, making you seriously consider replacing it to maintain a smooth user experience.

In this article, we review together the signs and indications that indicate that it is time to change the iPhone battery, and how to make the right decision in this regard.

Reasons for iPhone battery deterioration and when to replace it

iPhone batteries, like any lithium-ion battery, degrade over time and with repeated use. There are several reasons why this happens, and here's a look at the most important ones:

1. Number of charge cycles: Every lithium-ion battery, including your iPhone battery, has a set number of charge cycles it can handle before it starts to lose its ability to hold a charge. After that number is exceeded, you will notice that the battery no longer lasts as long as it used to.
2. Exposure to high temperatures: Heat is the number one enemy of batteries. If your iPhone is exposed to high temperatures regularly, whether it is due to leaving it in a car under the sun or using it heavily while charging, this will accelerate the deterioration of the battery and make you think about changing the iPhone battery sooner than you expect.
3. Heavy use: Running heavy apps, games, and using the phone for long periods without turning it off can drain the battery faster.
4. Over time, your battery's performance will gradually decrease and you'll start wondering when to replace your iPhone battery to ensure continued optimal performance.
5. Improper charging: Using non-original or non-certified chargers, or leaving the phone connected to the charger for long periods after charging is complete, can cause battery deterioration. You must use original iPhone chargers and cables designed for the iPhone .

If you notice any of these signs, it may be wise to start thinking about replacing the battery to ensure the continued good performance of your device.

How do you know that the iPhone battery needs to be changed? Signs to pay attention to

When your iPhone battery starts to degrade, there are some signs that indicate it may be time to replace it.

If you are wondering when to change your iPhone battery, here are some signs to watch out for:

1. Rapid battery drain: If you notice that your iPhone battery is draining rapidly even with moderate use, the battery may have lost a significant portion of its ability to hold a charge.
2. Sudden shutdown of the device: If the iPhone suddenly turns off when you are using it, especially when the battery percentage is between 20% and 30%, this indicates that the battery is no longer able to provide stable power to the device.
3. Slow performance: A degraded battery can affect the overall performance of the device. If you feel that your iPhone is becoming slow or freezing when running certain apps, it may be because the battery is no longer able to provide enough power.
4. Device overheating: If you notice that your iPhone is getting excessively hot while charging or in use, the battery may be in poor condition and needs to be replaced.
5. System alerts: iOS occasionally sends alerts telling you that your battery health has degraded significantly.

Paying attention to these signs and signals can help you make the right decision and ensure continued good performance and safe use of your device.

The optimal period of time to use the iPhone battery before replacing it

Your iPhone battery is designed to last a long time, but over time, it starts to lose its ability to hold a charge efficiently. If you’re wondering when to replace your iPhone battery based on how long you’ve used it, here’s what you need to know:

1. Number of charge cycles: iPhone batteries are designed to retain 80% of their original capacity after about 500 full charge cycles. One charge cycle means using 100% of the battery’s capacity, whether that’s by charging it from 0% to 100% once or through several partial charges. After 500 charge cycles, the battery will begin to deteriorate significantly, and you may need to replace it.
2. Two to three years: On average, an iPhone battery lasts two to three years before it starts to noticeably lose its capacity. This period varies depending on how the device is used and environmental factors such as temperature.
3. Personal Usage Factors: If you are a heavy user who relies on your iPhone for multiple tasks throughout the day, you may need to replace the battery sooner than someone who uses the device moderately. Heavy use leads to increased charging cycles, which accelerates battery degradation.
4. iOS Updates: Continuous iOS updates can consume more power, especially if they contain new features that require additional resources. This can lead to your battery draining more quickly.

Ultimately, the optimal amount of time to use your iPhone battery before replacing it depends on several factors, including the number of charging cycles and how you use it. But in general, if you start to notice a decline in performance after two to three years of use, it's time to consider replacing it.

Does low battery affect iPhone performance? When should I replace the battery?

Low battery percentage significantly affects the performance of the iPhone. Over time, this effect can become more pronounced, prompting users to wonder when to replace the iPhone battery to maintain the device’s performance.

Here's when you should consider replacing them:

1. Low Power Mode: When the battery percentage drops to low levels (usually below 20%), the iPhone automatically activates Low Power Mode. This mode reduces the device's performance, such as slowing down the processor speed and reducing the brightness, in an attempt to preserve battery life for as long as possible.
2. Turn off background apps: As your battery gets low, iOS turns off some apps in the background to save power. This can impact your user experience, especially if you rely on apps that need to be constantly updated.
3. Sudden shutdown of the device: If the battery is very weak, the iPhone may suddenly shut down even with a reasonable battery percentage. This happens because the battery is no longer able to provide the device with the necessary power.
4. Overall performance impact: As the battery degrades, the overall performance of the device begins to decline. The iPhone may become slower to respond, take longer to open apps, and may get hotter than usual. All of these things indicate that the battery is no longer able to meet the device’s needs.
5. Battery Alerts from the System: If you receive messages from the iOS system indicating that the battery health has deteriorated significantly and needs to be replaced, this is a clear sign that the battery is in poor condition.
