How long does an iPhone last on average?

On average, an iPhone lasts 4 to 6 years, with many users keeping them longer (7-10 years) thanks to Apple's strong hardware and lengthy software/security updates, though performance may slow and batteries will need replacing around the 2-3 year mark to maintain optimal use. The real longevity depends on care, battery health, and user needs, with some older models still functioning years later, even if out of the latest OS.

What is the 20/80 rule in iPhone?

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%.

What is considered old for an iPhone?

An iPhone becomes "old" when it stops receiving current iOS updates, but officially, Apple categorizes them as Vintage (no sales for 5-7 years, limited service) or Obsolete (no sales for 7+ years, no hardware service). In practical terms, an iPhone is old when it's about 5-7 years past its release, lacks major software/security updates, and struggles with modern apps, though many older models remain usable for basic tasks.
 

Can I use an iPhone for 10 years?

Yes, an iPhone can physically last 10 years with good care, but its functional lifespan for new software, apps, and optimal performance is usually 5-8 years, with battery health being the primary limiting factor, though you can extend it significantly with battery replacements and by managing expectations about new features. While hardware endures, Apple typically provides major iOS updates for 6-7 years, and security updates for longer, after which performance and app compatibility decline. 

Is a 5 year old iPhone still good?

I've seen folks still using the iPhone X or even older ones that work perfectly fine while others can't resist upgrading every single year. Honestly, I feel like iPhones can easily last 4 to 6 years if you take good care of them. The hardware holds up and Apple keeps pushing updates for quite a while.

How Long Do iPhones Actually Last??

When should I replace an iPhone?

You should replace your iPhone when performance slows significantly, battery health drops below 80% (or drains too quickly), it stops receiving crucial security updates, or if you need new hardware features like advanced cameras or AI, but generally, iPhones last 4+ years with good care, so consider if repair costs outweigh upgrading or if new features justify the expense.
 

What iPhones will quit working in 2025?

Introduction & Clarification. First and foremost, it's important to clarify that no iPhone will literally stop functioning in 2025. Even older models like the iPhone 6 can still operate and perform basic tasks such as making calls, sending texts, and browsing the internet.

How much does it cost to replace an iPhone battery?

An iPhone battery replacement costs roughly $69 to $119 at Apple for out-of-warranty service, depending on the model (older models are cheaper, newer ones more expensive), but it's free with AppleCare+ if the battery health drops below 80%; third-party shops are often cheaper but vary in quality. For DIY, expect around $40-$50 for a battery kit, though risks are involved. 

What is the oldest iPhone still supported by Apple?

The oldest iPhones still receiving security updates are the iPhone 6S and the first-generation iPhone SE, as they are supported with the final updates for iOS 15 (like iOS 15.8.4) into 2025, though these are considered "vintage" and lack full support for newer iOS versions like iOS 26. For newer, fully supported iOS versions (iOS 26 as of late 2025), the oldest models are the iPhone XS, XS Max, and XR, released in 2018, which run the latest OS but are nearing the end of their major support cycle.
 

Which is the best older iPhone to buy?

For the best older iPhone, the iPhone 13 offers the best overall value with modern features and longevity, while the iPhone 11 is great for tight budgets, and the iPhone SE (2nd/3rd Gen) is excellent for compact design and basic use, but consider the newer SE 3 for better battery/speed. Prioritize models that still get current iOS updates for security, like the iPhone 13 or 14, to maximize future use. 

What is the best thing to do with old iPhones?

Old iPhones are great for repurposing as dedicated media players, smart home controllers, security cameras, or digital photo frames, and they also make excellent kids' devices, backup phones, or even temporary e-readers/gaming consoles, saving your main device and giving the old tech a new life.
 

Which iPhone is now outdated?

Apple considers an iPhone "obsolete" when it stops distributing it for sale over 7 years ago, meaning no hardware service is available and parts can't be ordered, though some older models (like iPhone 6/6 Plus, 5s, 5c) are currently on this list, no longer getting iOS updates or security patches, limiting functionality and security for users.
 

Should you charge your iPhone every night?

Yes, you can safely charge your iPhone every night, as modern iPhones have built-in tech like Optimized Battery Charging that prevents overcharging and manages heat, reducing long-term battery wear by pausing charging at 80% and finishing just before you wake. While it's fine to leave it plugged in overnight, it's not strictly necessary if your battery is still high, and using quality chargers helps, but wireless charging overnight can sometimes cause more heat than wired charging. 

What drains the iPhone battery the most?

The biggest iPhone battery drains are heavy app usage (especially games, social media, streaming), poor cellular signal (forcing searching), high screen brightness, and resource-intensive background activity like location tracking or constant refreshing, with video streaming/calls being major culprits due to screen and data use. You can see exact culprits in Settings > Battery, but often it's a combination of these factors working together. 

Is it better not to charge an iPhone to 100%?

Charging your iPhone to 100% isn't inherently "bad" and is safe due to built-in protections that stop charging at full, but consistently charging to 100% and leaving it plugged in, especially overnight, can slightly increase battery aging over time compared to keeping it between 20-80%. For optimal longevity, use features like Optimized Battery Charging to manage charging, which reduces stress by pausing at 80% and finishing closer to when you need it, rather than letting it sit at 100% for hours. 

Is Apple still doing the $29 battery replacement?

Apple's $29 iPhone Battery Replacement Program Ends December 31 - Business Insider.

Can I replace my iPhone battery myself?

Yes, you can replace your iPhone battery yourself, especially older models, but it requires patience, the right tools (special screwdrivers, prying tools), and following detailed guides (like from iFixit) carefully, as modern iPhones use strong adhesive and delicate internal components, risking damage if rushed. For newer iPhones, Apple's Self Service Repair offers genuine parts and manuals, but third-party kits are also common, though they might trigger "Important Battery Message" warnings. 

Is it cheaper to repair or replace an iPhone?

In late 2025, the oldest iPhones still receiving crucial security updates are the iPhone 6s and the original iPhone SE (1st Gen), both getting updates for iOS 15 (like iOS 15.8.5), while the iPhone 7 and iPhone 8 series are likely at the end of their main support, though older devices might get rare patches, the iPhone XS/XR are also getting older but might still see some security support. For full modern features and app compatibility in 2025, you need an iPhone 11 or newer for iOS 18, but the 6s/SE1 remain functional for basic tasks with security, making them surprisingly long-lived, despite performance limits for newer apps. 

Which iPhone was the most popular?

How often should you switch off an iPhone?

You should turn off your iPhone at least once a week for a few minutes to clear memory, improve performance, and reduce potential security risks, say many tech experts, even though Apple doesn't strictly require it. This weekly reboot helps refresh the operating system, clear temporary files, and stop background processes that can slow things down, acting like a fresh start for your device.
