It is common knowledge that communicating over WiFi is more efficient than using the 5G cellular network, but by how much exactly? That’s exactly what PhoneBuff set out to measure in its latest battery life benchmark test.
Using an iPhone 17 Pro Max, the test simulated general phone usage including texting, web browsing, streaming video, Instagram and FaceTime. Once on 5G, once on WiFi. The final timings are perhaps closer than you’d think.
