Apple should update the outdated 60Hz display refresh rate in its iPhone 15 lineup. Additionally, Apple's charging speeds lag behind competitors, with the industry offering options up to 150W for faster charging.
Non-Pro iPhone models lack higher refresh rates like 90 Hz or 120 Hz, which is outdated compared to midrange Android phones. Faster refresh rates would improve display smoothness and enable features like Always On Display for more users.
Apple's iPhone 15 charging speed at 25W falls behind competitors' offerings of up to 150W. Despite concerns about battery health, Apple can optimize to balance speed and longevity. Faster charging technology can meet consumer expectations for quicker charging times.
While Pro iPhone 15 models boast USB-C transfer speeds of 10 Gbps, non-Pro models are stuck with the slower 0.48 Gbps rate. Standardizing the faster transfer rate across the lineup would benefit users dealing with large file transfers, such as 4K videos and high-resolution photos.
The iPhone 15's rear camera hump is unattractive and causes wobbling. Apple should follow Samsung and Google's lead to design a more stable and minimalist camera layout.
Choosing the smaller iPhone 15 Pro should not result in a loss of high-end features compared to the Pro Max model. Ensuring feature parity, such as consistent optical zoom capabilities, across all Pro models would provide users with a more equitable experience regardless of device size.
