In all mobile devices, whether it is smart watches, laptops or mobile phones, the battery is one of the most important components. Even if they are very efficient devices, iPhone devices are no exception to battery performance degradation and the time will come when you have to replace the iPhone battery.
Like all lithium-ion batteries, those on iPhone devices lose their efficiency over time. Throughout the use, the battery begins to degrade and provide low performance. Whether the iPhone is used intensely or not, the aging of the battery and the reduction of its performances are inevitable. If you are not sure you have to do this refresh of your device, the guide below could help you find out whether or not your iPhone has a problem with battery status.

Why and when to replace your iPhone battery?
În primul rând, chiar dacă bateria iPhone a dat sau nu semne de degradare a performanțelor, poți verifica oricând starea de funcționare a acesteia și capacitatea maximă de încărcare din: Settings > Battery > Battery Health & Charging > Maximum Capacity. Aici este afișat procentul care reprezintă capacitatea actuală a bateriei comparată cu capacitatea sa maximă originală atunci când era nouă. O baterie cu stare de funcționare normală trebuie să aibă cel puțin 80%. În condiții normale de utilizare a dispozitivului iPhone, la procentul de 80% pentru starea bateriei se va ajunge după aproximativ 2 ani sau 500 de cicluri de încărcare.
If this percentage from the battery health is 80%, it is not time to replace your iPhone battery. This is in a normal working condition and the performance of the device should not be negatively affected because of the battery.
Starting with iOS 17.4, on the iPhone 15, iPhone 16 devices and newer models, the battery health is displayed directly in its settings and information menu.

When the maximum charging capacity drops below 80% you can keep in mind that the time to replace the iPhone battery is approaching. In addition to this percentage that indicates the health of the battery, the iPhone can give other signs of wear.
Low autonomy
One of the first signs that you have to replace the iPhone battery is a much short lifespan. If you have noticed that you have to charge your iPhone several times a day, even with moderate use, it is a clear sign that the battery has started to lose its capacity.
The iPhone closes unexpectedly
Another sign that the battery should be replaced is when your iPhone stops suddenly, even when the battery level is still high. This behavior is a clear indicator of a major problem with the battery. This behavior is especially encountered in winter, when the iPhone housing is colder.
The performance of the iPhone is affected
Apple has introduced a system that limits the performance of the device (Peak Performance Capability) when the battery is very used to prevent unexpected stops. If your iPhone moves harder or the applications open late, it may be due to an aging battery.
The iPhone is overheating frequently
If you have noticed that your phone gets abnormally warming even during simple activities, it could be another consequence of a used battery. Constant overheating can affect other components and lead to more serious problems. It is a clear sign that you have to go to an Apple authorized service or a reliable service to replace the iPhone battery.
Swollen battery
In rare cases, a defective battery can begin to swell, which can cause damage to the phone or even represent a safety risk. If you notice that the phone screen begins to rise or that the case has started to deform, go to an authorized service to replace the iPhone battery.
Messages announcing you need to replace the iPhone battery
Sometimes, on the iPhone screen may appear messages that warn you that the battery should be replaced in a service or that the phone performance is affected by the battery condition.
How much does it cost to replace the iPhone battery?
The price of replacing an iPhone battery may vary depending on the service, the phone model and the geographical region you are in. In general, the price of changing a battery in an Apple authorized service varies between $ 99 for the latest iPhone models (iPhone 15 Pro, iPhone 14) and drops to $ 69 for iPhone 5S, iPhone 6 and iPhone 7.
On the Apple's service page you can check the estimated replacement price iPhone for your model: iPhone Battery Replacement.
Why is the iPhone battery used and how can you extend your lifespan?
Battery wear appears mainly due to the passage of time, in the natural aging process/ any battery naturally degrades as it is used, due to chemical wear, which leads to decreased charging capacity.
Another important factor that can reduce the battery life is the use of the iPhone. Apple states that a battery operates normally up to about 500 complete charging cycles, when the maximum charging capacity decreases to about 80%.
To extend the battery life, it is advisable to avoid the use of applications or games that quickly consume energy, do not expose the iPhone to excessive heat or direct sunlight for long periods and avoid charging the device when the battery has more than 20% remaining energy.
What is the optimized charging of the iPhone battery and how to activate?
Optimized charging is a function meant to extend the lifespan of the iPhone battery and postpone the time you have to replace the iPhone battery. You can activate this option by following the steps: Settings → battery → battery health and charging → Optimized battery charging.
With this activated function, the iPhone will learn the time intervals when you leave it for longer periods (for example, at night) and will adjust the loading process. Normally, the device will charge the battery up to 80%, and to reach 100%, it will proceed to a slow charging process, thus protecting the battery. Thus, you will not need to replace the iPhone battery too soon.
