The display is impressively bright, despite the 60 Hz, which I thought might be a drawback coming from a 120 Hz Android device. Surprisingly, it feels the same. The battery life is solid, providing around 1.5 days for mild phone users. As a developer, with light usage for content consumption and social media, I get around 8 hours of screen on time with 25-30% battery left. It charges quickly to 50% and then trickle charges to 100%, adapting to usage patterns for faster charging. Initially, there were some battery drain and heating issues, but they resolved as the phone learned my usage patterns.

Upgrading from iPhone 11 to 15. Good one full day battery from 85% to 30% for normal users without gaming. Use apple adapter for good battery life. Camera images were very natural.. Good sound output. For first week usage you may feel heat.. Then no heating issues so far.

Design One of the most noticeable changes to the iPhone 15 is its new design. The phone now has rounded edges, which makes it feel more comfortable in the hand. It also has a new camera bump that is less pronounced than the one on the iPhone 14.

The iPhone 15 is a solid upgrade with improvements across the board. The design is sleek, the display is gorgeous, and the performance is top-notch. The camera takes stunning photos, and iOS 17 offers some exciting new features. While there are a few minor shortcomings, the overall experience is undeniably impressive.
