Apple iPhone 13 Review: A Revised Upgrade 7

The Apple iPhone 13 is a refurbished upgrade to last year’s iPhone 12 that improved everywhere with a new camera system, faster chips, larger batteries and, fortunately, a smaller notch. It also gained some weight, but remained more durable and powerful than setting a standard for Android phones. We’ve taken the iPhone 13 for a spin through our testing process to see how it upgrades and whether it’s the most valuable for the iPhone in 2021.

Apple iPhone 13 Specifications and Features

The iPhone 13 gets a brighter Super Retina XDR OLED display on top of the iPhone 12 but the size stays the same at 6.1 inches. The notch cutout is now 20% smaller than before giving you a little more screen estate. It weighs 174 grams and is 7.7 mm thick which is still quite light because it is made of space-grade aluminum and is suitable for one-handed use.

The iPhone 13 is powered by an A15 bionic chip built in a 5nm architecture with two high-performance cores and four power-efficient cores that offer performance gains across the board and under different working pressures. Base storage has been doubled from 64GB on the iPhone 12 to 128GB on the iPhone 13.

The Apple iPhone 13 uses a new camera sensor placed in a diagonal format with a 12MP camera with f / 1.6 aperture and sensor-shift OIS, and then a 12MP ultra-wide camera with 120-degree FOV. The new cameras support deep fusion with Dolby Vision HDR, Smart HDR4, photographic style and cinematic mode.

Apple iPhone 13 performance

Every year the iPhone sets a new benchmark in performance and there is always an improvement in everything you can do on the phone. The iPhone 13 follows tradition and tops the charts in terms of performance, gaming, battery and ease of use.

This year we have the A15 bionic chip with hexa-core CPU, quad-core GPU and 16-core neural engine for machine learning work, which enhances the iOS 15 experience. The iPhone 13 feels very fresh to use and iOS ensures that you always get stable and fluid performance. While Apple has reserved a high refresh rate display for Pro models, the iPhone 13 doesn’t let you feel like it’s running at a 60Hz refresh rate. This is because of the close combination between hardware and iOS 15 which optimizes the system for a smooth performance.

The iPhone 13 excels at the synthetic benchmark compared to its Android counterpart. In the AnTuTu test, the iPhone 13 got a high score, which knocked out phones like the OnePlus 9 Pro and ROG Phone 5. It tops the charts with impressive numbers in GeekBench CPU tests that mimic real-world tasks in both single-core and multi-core computing.

The iPhone 13 3DMark with high scores on GPU tests like Wildlife and GFXBench Metal that demonstrates its prowess in playing graphic-intensive games like Call of Duty Mobile, Battlegrounds Mobile India and many more. Even with a quad-core GPU, gaming on the iPhone 13 is a great experience but you’ll find better performance on iPhone 13 Pro models with a 5-core GPU that compliments it with a 120Hz refresh rate display.

We used Gamebench to record gameplay metrics where the iPhone 13 runs COD Mobile at 59 FPS in 100% stability. It was able to run BGMI on Ultra HD graphics at Ultra Frame Rate where GameBench recorded 39FPS with 100% stability. We brought the graphics down to HDR, while we got a toggle to enable extreme frame rates where Gamebench recorded 59FPS at 100% stability.

All of this only highlights the great gaming performance you can expect from the iPhone 13. This is a cakewalk when it comes to everyday tasks like replying to an email, sending a message on WhatsApp, playing music or switching between those apps. For the latest iPhone. Even under heavy workloads such as photo or video editing, the iPhone 13 is able to deliver a consistent and polished experience that shows no signs of slowing down. And given Apple’s track record of supporting more than 5 years of iOS updates, the iPhone 13 will feel as fresh every year.

Apple iPhone 13 Battery Life

The iPhone 13 is equipped with a larger 3227mAh battery than the previous generation and supports 20W faster wired charging and 15W MagSafe wireless charging. Now, considering the 50W charging speed these aren’t really some great specs and big batteries are now relatively common in terms of Android.

That being said, the battery life of the iPhone 13 has improved over the last generation and depending on your usage you can get over 7+ hours of screen-on time from this phone. Of course, if you regularly play games or record videos, the battery will start to drain quickly. When charging, the iPhone 13 tops up in about 1 hour 40 minutes using a Lightning adapter from the standard Type-C.

Apple iPhone 13 Camera Review

For the iPhone 13, Apple has upgraded the previous generation of camera sensors to make images brighter and sharper. The sensor-shift brings much more stability to OIS videos, and it’s great that this feature has moved from the Pro model to the standard iPhone. There’s also the Smart HDR4 and the new photographic style that basically presets and optimizes images for color and contrast.

Unlike its Android counterpart, Apple did not jump on the bandwagon to use the high-resolution sensor in the iPhone 13 and instead relied on ML algorithms and optimizations to create the most natural-looking images. Compared to the iPhone 12, there is a one minute jump in image quality but it is still a jump.

The iPhone 13’s camera really comes close to replicating what you see with your eyes and you get bright, colorful and sharp pictures. However, since a phone like the OnePlus 9 Pro uses a high-resolution sensor, you’ll get better detail capture and sharpness that you can perceive as you zoom in on the image.

Day shots from the iPhone 13 have a good dynamic range and color tones, both outdoor and indoor, and control the highlight and saturation levels. The natural bokeh looks great in images taken from the main camera and is also very good at capturing accurate details in shady areas.

Ultra-wide cameras are also great for taking some good landscape pictures but they often do not focus on the edges. The colors of the Ultra-Wide camera are in sync with the colors you get from the main camera and there is very little difference in how both sensors perceive dynamic range and contrast which is great because you get almost identical color from both cameras.

The portrait mode of the phone is capable of taking some great pictures with bokeh effect. There is also portrait lighting which gives your portrait a unique look with six different effects

A big highlight of this year’s cameras is the cinematic mode that brings depth-of-field and rack focus to videos. The camera is able to automatically shift focus between two subjects within a frame and add a subtle bokeh to the background. This mode records in Dolby Vision HDR and lets you edit the focus post-recording.

When it comes to video, the iPhone camera is always at the top of the game and is no different than the iPhone 13 and records 4K HDR video in Dolby Vision. The videos on the iPhone 13 look great and the colors are close to the natural color tones which is great for people who make regular videos. Sensor-shift OIS also works well and reduces jolts and jolts from video.

At night, however, iPhone cameras capture a lot of things with Android phones because images often lack sharpness, and sadly, Night Mode doesn’t live up to its potential.

The selfie camera gets the same features as the rear cameras and is one of the best in the business with accurate skin tone and details. The phone misses a macro camera (reserved for Pro models) which is common with Android phones in this price range.

Apple iPhone 13 display

The iPhone 13 has a 6.1-inch XDR OLED display that is perfect for watching videos and movies. The display is vibrant and bright with good sunlight and the Face ID notch is now smaller than before.

Although the Android ecosystem has moved from big notch cutouts to punch-holes and in-screen selfie cameras, the iPhone 13 still has a wide notch, and for good reason. Selfie camera with 3D biometric sensor enables facial recognition which is one of the most advanced ways to unlock the phone.

We used Calman and SpectraCal C6 calorimeters to test the display of iPhone 13. According to data from Calman, the iPhone 13’s display has a typical peak brightness of 536 nits. Further experiments have shown that the iPhone 13’s display has an average Delta 1.9 in sRGB color space and a better RGB balance than the iPhone 13 Pro’s display, which is quite good. The display offers a wide range of color gamut, something that is proven by the Calman test.

In everyday use, the iPhone 13 provides a superior viewing experience and is very well tuned to reproduce a variety of colors. Even if the refresh rate is locked at 60Hz, it means you’ll get longer battery life, and system-level optimization will somehow make the whole experience smoother and smoother.

Apple iPhone 13 build and design

Although the iPhone 13 is a bit thicker and heavier than the iPhone 12, it follows the same design policy as the latter. The iPhone 13 has a flat aluminum frame with ceramic shielded glass, which makes it quite stiff and protects against drops.

Although I didn’t want to test the durability of the new iPhone, it dropped 5+ times during my use, and neither the screen nor the rear glass showed any signs of damage, except for one or two marks on the frame. The iPhone 13 is also IP68 rated which means it is protected from dust and water which is great for everyday use.

The iPhone 13 looks very premium when you hold it in your hand and has an ergonomic build that makes it easy to use with one hand. When gaming, the edges of the phone do not make things uncomfortable and you can play games on it for hours without any unwanted strain.


The iPhone 13 takes the best from the iPhone 12 and adds new and improved features that make it a very refined upgrade this year. The phone features a new camera sensor, a brighter display, a faster A15 bionic chip than before and offers great improvements in battery life. Cameras capture some gorgeous images in daylight but want to get more out of night images. Cinematic mode opens up new ways for you to create shallow depth-of-field videos, and it will be better to recognize the edges over time.

Priced at Rs 79,900, the iPhone 13 is a no-brainer for anyone looking to upgrade to the iPhone 11 or earlier. For those who want to upgrade their iPhone 12, the iPhone 13 is only a growing update and it does not guarantee a switch, especially since the iPhone 12 is now available at a lower price. If you’re someone who wants to get into the Apple ecosystem, then the iPhone 13 is a very reliable starting point because it saves for some features like high frequency refresh screen, full of all the latest bells and whistles.
