For technology enthusiasts like us, our favorite gadgets have long memories. And while the award for biggest battery failure goes to Samsung, creator of the explosive Galaxy Note 7, Apple isn’t immune to criticism either. In fact, some consider “Batterygate” to be one of the biggest failures in Cupertino history. The company admitted its mistake and aiming to pay $500 million Because of the ensuing class action lawsuit.
But it’s important to recognize when the pendulum swings the other way, and this week iPhone 15 owners received a battery-related upgrade without knowing it. During the development of iOS 17.4, Apple retested the iPhone 15 series and found that the maximum battery capacity met higher standards than originally specified. Both the iPhone 15 and iPhone 15 Pro handsets can retain at least 80% of their original capacity after 1,000 charging cycles. This is double the original claim that all iPhone 4 models launched last fall retained 80% of their original capacity after 500 full charging cycles.
Everyone thought this would start to cause battery failure after just over 18 months of daily charging, but the iPhone 15 (or 15 Pro Max) actually lasts twice that, or 3. This means that it will fail after a year has passed. It is struggling to reach 80% of its original capacity.
Apple hasn’t said exactly how it came to its new conclusion, saying only that additional testing consisted of 1,000 charges and discharges under specific conditions. Like all cell phone manufacturers, the company has a set of battery testing procedures that represent common use cases.
But the transparency around battery replacement is nonetheless refreshing for the company, which suffered in 2017 when the first reports of throttling in older phones began to emerge. Perhaps learning from that mistake, iOS 17.4 moved battery cycle count to a more prominent position. Previously buried in the “About” section, you can now find it along with other battery information. Settings > Battery > Battery Status.
To be clear, the iPhone 15’s battery wasn’t in bad shape to begin with. In our review, the 6.1-inch iPhone 15 boasts a 3,349 mAh battery based on regulatory listings (Apple doesn’t list the battery size), which is a fraction of the 3,279 mAh battery in the iPhone 14. It’s an improvement. The 30 minute jump was seen by We put the phone through Tom’s Guide’s battery test. The iPhone 15 lasted 11 hours and 5 minutes. Unfortunately, the iPhone 15 Pro only lasted him 10 hours and 53 minutes, but it was still a 40 minute improvement over the iPhone 14 Pro.
As someone who rarely goes without the best portable charger, battery anxiety doesn’t really bother me. But the whole idea of a company improving a product after I buy it is something I respect. That’s why I’m always looking forward to seeing what new software updates bring. For free. Google is doing the same with feature drops for his Pixel devices, and with update support extended for his seven years, things are only going to get better for Pixel users.
I’m always excited to see what new software updates add for free.
Apple’s retested impromptu battery upgrade is currently only seen on the iPhone 15 series, but Apple is also considering older iPhone models to see if they perform better than originally stated. I understand. So there’s probably some frenetic battery testing going on at Apple Park right now.
Of course, there are some steps you can take to maximize the lifespan of your iPhone’s battery.we We covered many of them hereBut here are three key points that Apple itself emphasizes:
- iPhone is designed to operate in a wide range of ambient temperatures, but the sweet spot is between 62° and 72° F (16° and 22° C).
- Do not charge or leave iPhone in high-temperature environments (above 35°C), such as prolonged exposure to direct sunlight.
- If you store your iPhone for an extended period of time, try to keep it at half charge.
Meanwhile, here is How to limit iPhone charging to 80% If you want to minimize the risk of overheating and keep the lithium-ion battery inside your iPhone healthy for longer.
