What is the issue with 15?


The issue with your iPhone 15 is that the battery is failing and it will need to be replaced.....if the swelling has not caused the iPhone's frame to be bent or distorted.


A software update will not cause a hardware component to fail. The battery would have failed no matter whether the iPhone was updated or not. It happens.


Since the iPhone 15 is out of warranty, you will pay for repairs. That is the way that warranties work.


The cost of the battery is about $99 (U.S.) at the Apple Store / Genius Bar or Authorized Apple Service Provider (AASP).


You can find a list of authorized shops in your area using this link:

Battery swelling is not caused by iOS itself, nor does it normally happen suddenly in a single day. A swollen battery is generally the result of gradual internal deterioration or damage to the battery cells, which may have been developing for some time before the swelling became visible.


In some cases, the deterioration can be accelerated by excessive heat, a faulty or poor-quality charging cable, a defective charger/power adapter, unstable charging equipment, physical damage, or prolonged exposure to high temperatures. However, it is not possible to identify the exact cause simply from the fact that the battery has swollen.


You may also have noticed warning signs earlier but not connected them with the battery—for example, unusual heating while charging, charging becoming intermittent or unusually slow, the battery draining faster than normal, unexpected shutdowns, or the phone failing to charge properly. These can be indications that the battery was already deteriorating.


An iOS update does not normally cause a physically swollen battery. An update can temporarily increase processor activity and battery usage while the system performs tasks such as indexing and optimization, which may make the iPhone feel warmer or cause increased battery drain for a short period. That is different from causing the battery cells to physically swell.


Therefore, if swelling is discovered shortly after an iOS update, the timing does not by itself establish that the update caused it. The underlying battery deterioration or damage would generally have started earlier, even if the visible swelling only became apparent later.


If the battery is visibly swollen, stop using and charging the iPhone and have it inspected by Apple or an authorized service provider. Do not press on the swollen area or attempt to open the phone yourself.

DON'T Use it

DON'T charge it

Take it to Apple Store for immediate repair

Not every issue an individual encounters on their device can be attributed to an iOS update. If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook. The absence of such widespread reports strongly indicates that the issue is not systemic, but rather specific to the device in question.

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.
