The upcoming iPhone 13 models for 2021 are expected to come with a smaller notch and a thicker body to accommodate possibly a bigger battery. According to MacOtakara, the iPhone 13 lineup will retain the iPhone 12's chassis with the flat edges but will be roughly 0.26mm thicker.
The notch at the top of the screen might be reduced due to the change in the position of the receiver placed at the top of the phone. The camera bump noticeable in the iPhone 12 lineup will not be so apparent in the iPhone 13 lineup as the overall thickness will be increased. The report claims that the iPhone 13 lineup will follow the footsteps of the iPhone 12 models. Also, the camera sensors will be similar. According to the popular analyst Ming-Chi Kuo, the iPhone 13 and 14 models will retain the seven-element lens system till 2022.
The iPhone 12 lineup was criticized for not having a higher refresh rate, which has been the key specs in the Android world for two years now. Apple considered including a higher refresh rate in its top model, but the production failed to implement it in time. Now, the report confirms that finally, Apple will include a 120Hz LTPO OLED display with a variable refresh rate to the iPhone 13 series. However, earlier reports had suggested that only the Pro model will get this feature. The upcoming series will also include better connectivity options. The latest Wi-Fi 6E announced in 2020 will also be included.
