If compared to its predecessor iPhone XR, it should have an hour longer battery life. This means if you own an iPhone X, you will feel the difference, when upgrading.
The new A13 processor compared to A11 will make you notice the increase in speed, but since the A11 is still a very capable processor, switching to A13 won’t impact day-to-day usage that much.
In terms of durability, the new iPhone 11, same as X, is water and dust resistant. However, the iPhone 11 can endure water up to 2 metres deep, where iPhone X could survive in only 1-metre deep water.
Verdict- if you feel like you’re phone’s battery life is not enough for you, iPhone 11 is a clear choice. You will feel the difference and be able to enjoy this phone for longer without charging.
