Apple‘s battery issues with various iPhone models have been an ongoing concern. While the iPhone 12 seemed to stabilize the situation, the release of the iPhone 14 reignited doubts about battery life. Now, the iPhone 15 has also fallen prey to battery problems, setting off alarm bells among users.
Users of the iPhone 14 were disheartened to discover rapid battery degradation, with the iOS system showing a significant drop in battery health just a year after purchase. Nobody wants a €1,000 smartphone plagued by battery problems, but that’s precisely what some iPhone 15 owners are experiencing.
The Culprit: Cheaper Battery Cells

The cause of this swift battery deterioration in both the iPhone 15 and its predecessor, the iPhone 14, can be attributed to the use of cheaper battery cells. These battery cells offer only around 600 charge cycles, which is notably less than the 800 to 1,600 cycles commonly found in high-end smartphones. Batteries with 600 cycles are typically used in high-performance devices, like portable vacuum cleaners exceeding 100W.
The concerning issue is that the iPhone 15 does not belong to the category of high-performance devices, as it doesn’t require the same level of power. As a result, using a cell with just 600 charge cycles is inadequate for this smartphone. Apple’s decision to opt for such low-quality battery cells appears to be motivated by cost-cutting measures, an unfortunate choice for a high-priced device.
Battery cells serve as protective shields during charging to prevent overheating or other problems, but they come with a factory-set lifespan. Once that lifespan is exceeded, battery degradation accelerates.
Checking Your iPhone Battery Health
Apple provides a feature to monitor your iPhone’s battery health, allowing users to gauge the status of their device’s battery. Here’s how to check your iPhone battery health:
- Open your iPhone’s settings.
- Select the ‘Battery’ section.
- Access ‘Health and battery charge.’
- You’ll see a percentage indicating battery health.
A brand-new iPhone 15 should show 100% capacity. If not, it’s advisable to reach out to a technical service center and take advantage of the device’s warranty.

In the pursuit of offering cutting-edge technology, Apple’s choice to compromise on battery quality in the iPhone 15 has left some users with a sour experience. While cost-saving measures can be beneficial, they must not come at the expense of a device’s core functionality, particularly when users invest a significant sum in acquiring it.
