Apple iPhone 4s

Apple iPhone 4s

The iPhone 4S was released in 2011, and while it is now over a decade old, it is still a capable smartphone for basic tasks. It features a 3.5-inch Retina display, an 8-megapixel rear camera, and a 1.0 GHz dual-core A5 chip. It originally ran iOS 5, but can be updated to iOS 9.3.6.


The iPhone 4S has the same iconic design as the iPhone 4, with a glass front and back, and a stainless steel frame. It is available in black and white. The phone is well-built and feels solid in the hand.


The iPhone 4S has a 3.5-inch Retina display with a resolution of 640 x 960 pixels. The display is sharp and vibrant, and it is still capable of looking good in 2023.


The iPhone 4S is powered by a 1.0 GHz dual-core A5 chip. The phone is fast and responsive for basic tasks, such as browsing the web, checking email, and using social media apps. However, it may struggle with more demanding tasks, such as playing modern games or editing high-resolution photos and videos.


The iPhone 4S has an 8-megapixel rear camera with LED flash. The camera can take good photos in good lighting conditions, but it struggles in low light. The phone can also record 1080p video at 30fps. The front-facing camera is a VGA camera, which is very low resolution by today’s standards.

Battery life

The iPhone 4S has a 1432mAh battery. The battery life is still good for basic tasks, but it may not last a full day of heavy use.


The iPhone 4S originally ran iOS 5, but can be updated to iOS 9.3.6. iOS 9.3.6 is a bit outdated, but it still receives security updates from Apple. The phone has access to the App Store, where you can download millions of apps and games.


The iPhone 4S is a good smartphone for basic tasks, such as browsing the web, checking email, and using social media apps. It has a solid design, a good display, and a decent camera. However, it may struggle with more demanding tasks, and its battery life is not great.

If you are looking for a basic smartphone that is still supported by Apple, the iPhone 4S is a good option. However, if you can afford it, you would be better off buying a newer iPhone with a faster processor, a better camera, and longer battery life.
