iPhone 12 vs. Samsung Galaxy S21: What’s the Difference?

The iPhone 12 and the Samsung Galaxy S21 are among the high-quality smartphones on the market. While both devices offer a range of features and capabilities, there are some key differences to consider when choosing between the two.


Apple has long been known for its sleek, eye-catching design, and the iPhone 12 is no different. The iPhone 12 has a more angular design with a flat-edge stainless steel frame and a ceramic shield front cover, designed to be more durable and resistant to drops. The Samsung S21, on the other hand, has a more curved design with a metal frame and a plastic back. In terms of size, the iPhone 12 is slightly smaller than the Galaxy S21. The iPhone 12 measures 5.78 inches tall and 2.81 inches wide, while the Galaxy S21 is 5.97 inches tall and 2.8 inches wide. In addition, the Galaxy S21 is slightly heavier at 5.96 ounces, compared to the iPhone 12’s 5.78 ounces.

When it comes to color options, the iPhone 12 is available in black, white, red, blue, and green, while the Galaxy S21 is available in Phantom Violet, Phantom Gray, Phantom Pink, and Phantom White.

The iPhone 12 also features Apple’s new Ceramic Shield technology, which is said to make the device four times more durable than the previous iPhones. The Galaxy S21 does not have any similar protective features. In terms of water resistance, the iPhone 12 has an IP68 rating, which means it can withstand up to six meters of water for 30 minutes. The Galaxy S21 can also survive underwater, but only at depths of 1.5 meters for 30 minutes.

Battery and Charging

The Samsung Galaxy S21 has a 4000 mAh battery, while the iPhone 12 has a 2815 mAh battery. As a result, the Samsung Galaxy S21 will last longer on a single charge than the iPhone 12. Although you would expect the S21 to have a higher battery life, it is not the case. Its 120Hz refresh life has a detrimental effect on the battery life.

Both phones support fast wireless charging but do not come with chargers in the box. The Samsung Galaxy S21 also features wireless PowerShare, allowing you to wirelessly charge other compatible devices with the phone’s battery. Unfortunately, this feature isn’t available on the iPhone 12.

When it comes to battery and charging, the Samsung Galaxy S21 has the edge over the iPhone 12. With its larger battery and faster charging options, it will provide more power and get you up and running much faster than the iPhone 12.
