Apple's Silent Throttle: How a Software Update Slowed Your iPhone and Forced an Upgrade

How Apple's silent update throttled old iPhones, generating billions in forced upgrades before a French court fined them for planned obsolescence.

The Discovery That Shook Apple

In 2017, developer John Poole noticed something strange. After installing the latest iOS update on his iPhone 6, benchmark scores plummeted by roughly half. The culprit wasn't an aging battery—it was new code Apple had added without telling anyone. This wasn't a bug; it was a deliberate slowdown.

Apple's Explanation: Battery Protection

Apple later confirmed the throttling, claiming it was to prevent unexpected shutdowns on older batteries. As lithium-ion batteries degrade, they can't deliver peak current, causing the phone to crash. Throttling the processor reduces power draw, stabilizing performance. But the issue wasn't the feature—it was the secrecy. Apple didn't notify users, offer an opt-out, or mention it in the update notes. Users experienced a slower phone with no explanation, naturally assuming it was time to upgrade.

The Business Impact: Billions in Forced Upgrades

A slow phone feels old. An old phone prompts an upgrade. According to reports, this silent throttling generated billions in additional iPhone sales as users replaced devices they thought were worn out. The strategy worked perfectly for years—until a single benchmark screenshot exposed the truth.

Legal Consequences: A Historic Fine

In 2020, France's competition authority fined Apple €25 million—the first-ever conviction for planned obsolescence in the country. Planned obsolescence is the practice of deliberately shortening a product's lifespan to encourage replacement. While Apple argued it was protecting batteries, the court found the lack of transparency and user consent violated consumer law.

How to Protect Yourself

  • Monitor battery health: Most smartphones let you check maximum capacity. Consider a battery replacement when it drops significantly.
  • Read update notes: Before installing major OS updates, search for user reports about performance changes.
  • Disable throttling: On some devices, you can disable performance management in battery settings—but this may increase shutdown risk.
  • Consider third-party diagnostics: Apps can benchmark your device before and after updates to detect changes.

The Bigger Picture

This case highlights a tension between user experience and corporate incentives. While battery protection is a legitimate engineering goal, hiding it from users undermines trust. The lesson for consumers: stay informed, question unexpected slowdowns, and remember that a battery replacement is often cheaper than a new phone.

FAQ

Did Apple really slow down old iPhones on purpose?

Yes, Apple confirmed in 2017 that iOS updates throttled processor performance on iPhones with degraded batteries. The stated reason was to prevent unexpected shutdowns, but users were not informed or given a choice, leading to accusations of planned obsolescence.

How much money did Apple make from slowing down iPhones?

According to reports, the practice generated billions in additional iPhone sales as users upgraded devices they believed were worn out. The exact figure is disputed, but a French court fined Apple €25 million for deceptive commercial practices.

Can I check if my iPhone is being throttled?

Yes. On iPhones with iOS 11.3 or later, go to Settings > Battery > Battery Health. If performance management is active, you'll see a message. You can also use third-party benchmarking apps to compare performance before and after updates.

Is planned obsolescence illegal?

In some jurisdictions, yes. France has laws against planned obsolescence, and Apple's 2020 fine was the first conviction under that law. Other countries have consumer protection laws that may apply, but enforcement varies.

What should I do if my iPhone feels slow after an update?

First, check your battery health in Settings. If it's below 80% capacity, consider a battery replacement. You can also disable performance management in Battery Health settings, though this may increase the risk of shutdowns. If the phone is still slow, a factory reset or upgrade may be needed.

Does this affect other smartphone brands?

While Apple's case is the most famous, other manufacturers have faced similar accusations. Some Android phones have also been found to throttle performance after updates. Always research before updating and monitor your device's performance.
