An iPhone battery can technically last 5 years, but its performance significantly degrades, usually dropping below the recommended 80% capacity within 2-3 years of normal use, requiring replacement for optimal performance; factors like heat, charging habits, and usage intensity heavily influence its lifespan, with newer models like the iPhone 15 designed for 1000 cycles (around 4 years) before hitting 80% capacity, while older ones hit that mark around 500 cycles (about 2 years).
No matter what you do, your iPhone® battery has a limited shelf life. As it ages, the battery slows—so a full charge won't last as long. Most batteries are good for at least 2 to 3 years, often longer, but how do you know when to replace your iPhone battery? At Asurion, we help millions of people maximize their tech.
It still received new iOS versions and updates. What exactly is throwaway about that when compared to the hundreds of variants Samsung and others produce with a 2 year lifespan and then no updates after? “Throwaway” may be hyperbole, but the average lifespan in terms of iOS versions for an iPhone is about 5-6 years.
Generally, your battery can last three to five years. That's good news because, thanks to technological advancements, the car battery lifespan is longer than before.
How Long Does Apple Support iPhones. Starting from the iPhone 15 lineup, Apple documented the support period which is “minimum 5 years from the first supply date”, according to this UK PSTI compliance statement. Apple is pretty good at supporting their iPhones for the long haul and we'll give credit where credit is due ...
Yes, the iPhone 15 is still a great buy in 2025, especially if upgrading from an iPhone 12 or older, offering significant improvements in battery, camera, Dynamic Island, and USB-C at a much lower refurbished price. It delivers excellent performance and long-term value, but users coming from Pro models or wanting the latest AI features might prefer the newer iPhone 16 or 17, as the base 15 lacks the 120Hz ProMotion display found in Pro models.
Most car batteries need replacing after 3–5 years, regardless of driving habits. Waiting for a dead battery is not the best strategy. As your battery life diminishes, it can strain other components, like the alternator, and lead to bigger issues.
The POWER FLASH Alkaline Battery offers long-lasting power and a leakproof design, ensuring a 10-year shelf life. Ideal for household and office devices, these batteries provide reliable performance without compromising safety.
Typically, the average car battery life is between three and five years. Pushing a battery longer than five years, even under perfect driving conditions, could cause your battery to fail without notice.
While 90% battery health is generally acceptable, it does mean the battery has degraded somewhat. Battery health may continue to decline with heavy use. An iPhone with 90% battery health today could drop below 80% within 2 years, depending on usage patterns. However, if you're a regular user, you're good to go!
An iPhone hit the $2,000 price point with the iPhone 17 Pro Max (2TB variant in late 2025), catering to heavy professional users, but the base models remain much cheaper, while the original 2007 iPhone started at $499 (4GB) or $599 (8GB) with a contract, and rare sealed first-gen iPhones now sell for over $100,000 at auction.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
For optimal battery health, the recommended battery percentage to charge your phone is between 20% and 80%. It's best to avoid extremes, such as letting the battery reach too low to 0% or consistently charging it to 100%.
A 76% battery health is considered okay if your device lasts your day, but it's below Apple's recommended 80% threshold for optimal performance, meaning you'll likely experience shorter battery life and potential slowdowns, making a battery replacement a worthwhile consideration for improved longevity and speed.
Yes, Apple will replace your iPhone battery at 80% capacity if you have AppleCare+, as it's covered at no extra cost; without AppleCare+, you can still get a paid replacement, but you might wait until performance is worse, though Apple may replace it if a diagnostic shows significant issues even if it's above 80%. The standard guideline for warranty service with AppleCare+ is replacement when capacity drops below 80%, but you can pay for replacement anytime.
Just last week, Northwest Normal University in Gansu, China, announced its own carbon-based nuclear battery that can last up to 100 years. Although the basis of this battery, carbon-14, is extremely rare, the South China Morning Post reported that China has a carbon-14 commercial reactor in Zhejiang.
The 80/20 battery rule suggests keeping lithium-ion batteries (like in phones, laptops, EVs) between 20% and 80% charge for daily use to maximize long-term health and lifespan, avoiding the stress of full discharges (below 20%) and prolonged full charges (above 80%) that degrade battery chemistry faster, though modern devices have built-in optimizations. It's a guideline, not a strict law, balancing battery longevity with convenience, as charging to 100% or dropping below 20% is fine for occasional use.
The Baghdad Battery, otherwise known as the Parthian Battery, was an artefact hypothesised to be an ancient version of a battery. Found in 1938 by a German archaeologist, the 'Baghdad Battery' could be 2,000 years old, and consists of a clay jar, a copper cylinder and an iron rod.
Excessive heat and cold.
Hot summer months can deteriorate your battery. Then, you notice that lack of power in the winter. To help avoid damage to your battery from heat, park your vehicle in a garage or under a shelter on hot summer days.
It is absolutely abnormal to lose 1% in 3 minutes of usage.
Some cars will get up to five or six years out of their battery, while others will need a new one after only two years. In general, your car will usually need a new battery after three to four years. Replacing your car battery is another part of routine maintenance.
Apple claims improvements, but in real life, it's still an “end of the day with 15–20% left” phone. The verdict? The iPhone 16 is the safe choice if you're upgrading this year. You're buying into Apple's next-gen ecosystem, you get all the latest features, and it'll last you longer than the 15.
Despite the immense success of the iPhone 17 in 2025, the iPhone 18 is not expected to arrive until the spring of 2027, leaving the iPhone 17 in the lineup as the latest standard model for over 18 months. ⬇️ Read more in the comments ⬇️
Yes, Apple has already released the iPhone 16 lineup, including the iPhone 16, 16 Plus, 16 Pro, and 16 Pro Max, announced in September 2024 as the successor to the iPhone 15 series, featuring larger displays, titanium designs, and the A18 chip for advanced Apple Intelligence. A more affordable model, the iPhone 16e, was also introduced, offering core features at a lower price point.
