The iPhone 7 features a 4.7-inch screen, while the iPhone 7 Plus boasts a larger 5.5-inch display. This size difference means the Plus offers more space for viewing content and better media experiences, but it also makes the phone less compact.

Bigger screens are not always better since they can reduce one-handed comfort and battery life efficiency. The 7 Plus’s bigger display is great for gaming, watching videos, and split-screen apps, but if you prioritize compactness, the smaller iPhone 7 may suit you best. Ultimately, “bigger” might mean better for media but not for everyday comfort or pocketability. [Apple iPhone Compare].

Interestingly, the iPhone 7 Plus with its larger screen actually benefits from a bigger battery, which tends to offer longer usage times compared to the smaller iPhone 7. So while the Plus’s screen consumes more power, its bigger battery generally balances it out, meaning you often get longer battery life overall with the 7 Plus. [GSMArena Phone Comparison].
