iPhone 5 Battery Life May Be Impacted Greatly by Cellular Signal Strength

Deep in its lengthy review of the iPhone 5, iLounge has performed an analysis on the battery life of the iPhone 5. The site tested the device under a number of conditions, including both cellular and Wi-Fi web browsing, voice calls, FaceTime calls, video recording, and video and audio playback.

The phone performed fairly well but iLounge found battery life struggled when transferring cellular data or making voice calls, which they speculated was due to a weak signal:
if you’re using your iPhone 5 in places a with a very strong (4- to 5-bar) LTE or 3G signal, your cellular battery life may approach that number, but if not, the cellular antenna will struggle to maintain a signal, and fall well short. Because LTE and 3G/4G towers are in a state of build-out flux right now, our tests suggest that many LTE users won’t come close to Apple’s promised numbers.

iLounge has the detailed results on its battery testing in its iPhone 5 review, but unsurprisingly, mileage will vary greatly depending on a number of factors including health of the battery, signal strength, screen brightness, and other considerations.

Newsflash.

ALL Cellphones, even dumbphones are affected by signal strength, the weaker the signal, the phone has to boost power to the radio to maintain a connection.

Turn on Airplane mode on pretty much any dumb or smart phone, you'd be amazed how long the battery lasts without having to power the radio, I did that with my old Samsung Replenish Android Phone after I got my S3, I think with airplane mode on, it lasted almost a week before it died, my old 3GS would go almost a week to.

In other news, the pope is catholic.

Good idea, I'm sure physics will be fixed by then.

Manufacturers love to BS the numbers

Little over 4 hours seems pretty poor, but obviously you'd have to compare it to other devices. Maybe WiMax takes less power or something because there's no way I could kill my phone in 4 hours, even HBO 4g streaming I watched 3 hours and still had 40% one time.
