Yes, an iPhone can physically last 10 years with care, but it will likely need battery replacements and will stop getting major software/security updates after 5-7 years, meaning performance and app compatibility will decline significantly, making it less practical for daily use by the decade mark. While the hardware often holds up due to Apple's build quality and long support (e.g., iPhone 5S got updates until 2023), the lack of new iOS features and security patches eventually makes it slow and vulnerable.
Most users use their iPhones for three to four years before upgrading to a new one. With battery replacements, you can extend this timeline to as much as five to six years. Beyond that, we recommend upgrading to a new iPhone to get the cumulative upgrade experience and the latest security and software updates.
The 20-80 rule for iPhones suggests keeping the battery charge between 20% and 80% to minimize stress on the lithium-ion battery, thereby extending its overall lifespan and health by avoiding the high-stress points of full discharge (0%) and full charge (100%). While not a strict necessity for daily use, this practice reduces battery degradation by avoiding deep discharges and the taxing final 20% of charging, helping maintain battery capacity longer, though modern iPhones have built-in features like Optimized Battery Charging to manage this.
If you want to keep using an iPhone for as many years as possible, avoid buying models that are already more than a year old. These models will get cut off from major iOS upgrades sooner than newer devices, which will make them unsafe to use in a shorter timeframe.
iPhone 6S is the oldest iPhone supported with security updates because it runs iOS 15, which was last updated in August 2025.
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.
It's especially important to avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity. That is, your battery won't power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further.
You can charge your iPhone every night even if the battery isn't fully depleted. iPhone automatically stops charging when the battery is fully charged, so it's safe to keep your iPhone connected to a charger overnight. Charging resumes automatically if your battery level drops below 95 percent.
The Risks of Using Unsupported Devices
Security Vulnerabilities: The most significant risk of using an unsupported device is the exposure to security vulnerabilities. Without regular software updates, your iPhone becomes an easy target for hackers.
Apple has removed three iPhones from its website. These include both iPhone 16 Pro models – iPhone 16 Pro and iPhone 16 Pro Max, along with the base iPhone 15 model.
Excessive Standby Battery Drain
Many iPhone 12 and 12 Pro users have noticed an unusual battery drain, sometimes losing up to 20% charge overnight, even in Airplane Mode.
When trading in or upgrading makes more sense. If your iPhone is several years old or has other issues like a sluggish processor, screen damage, or is no longer supported with iOS updates, trading in or upgrading could offer better value than just replacing the battery.
Most iPhones tend to get between six and eight years of support, which is way more than almost everything you can find in the Android sphere. If you want to update your iPhone or know if your current handset supports the latest iOS 26, you've come to the right place.
Average lifespan of a smartphone: In 2024, a smartphone has an average life span of 2.53 years. According to reports, iPhones last 4-10 years, while Samsung phones last 3-6 years. Many factors affect a smartphone's lifespan, including the condition of the screen, the hardware, and the battery's health.
The 20-80 rule for iPhones suggests keeping the battery charge between 20% and 80% to minimize stress on the lithium-ion battery, thereby extending its overall lifespan and health by avoiding the high-stress points of full discharge (0%) and full charge (100%).

Identify Your Usage Habits
For example, streaming videos or music, making calls, and gaming on the go typically cause your battery to drain much more quickly. Other culprits of battery draining include active applications in the background or constantly updating, such as real-time weather apps.
Question (xxi): What happens if you leave a device plugged in even after it is charged 100%? Explanation: Leaving a device plugged in after it is fully charged can cause the battery or device to overheat due to continuous charging.
For Android phones with LCD screens, the battery savings from dark mode are minimal. However, Android devices often come with additional power-saving features, such as battery-saver mode, which can help extend battery life. These modes often work in conjunction with dark mode to reduce overall power consumption.
iPhone battery's maximum capacity
It starts out at 100% (or just under), and as the battery ages, capacity decreases, which means you get fewer hours between charges. If the number you see under Maximum Capacity is more than 80%, you have a healthy battery, according to Apple.
Messages automatically uses the following screen effects for specific text strings:
*3001#12345#* on an iPhone activates the hidden Field Test Mode, a diagnostic tool for network engineers and power users to see detailed cellular data like signal strength (dBm), cell tower info, and network quality, accessible by dialing the code in the Phone app and pressing call, often after turning off Wi-Fi for accurate cellular readings.
You can double-tap or triple-tap the back of iPhone to perform actions such as taking a screenshot, turning on an accessibility feature, running a shortcut, and more. Go to Settings > Accessibility > Touch > Back Tap. Choose Double Tap or Triple Tap, then choose an action.
