iPhone 4S Battery Life: How Does It Compare to Other Smartphones?

The iPhone 4S's battery-drainpipe problem has been a hot stock concluded the past week. Plain the emplacemen-services system in iOS 5 is the main perpetrator behind the rapid exit of battery tycoo. Apple has acknowledged the situation and discharged a beta version of iOS 5.0.1, a future update that corrects the problem.

But the iPhone 4S is non the only smartphone with troublesome battery life. As my fellow Jared Newman puts it, "smartphone batteries stink." For instance, when the HTC ThunderBolt and the Samsung Charge debuted earlier this year, customers reported a poor shelling life span when each phone was hooked into Verizon's 4G network.

We wanted to see how the iPhone 4S compared to former apical smartphones (for the brimful list, determine the chart under). Since this is rightful a taste comparison, it International Relations and Security Network't the final word in battery life-time testing. For this article, we used the AT&T interlingual rendition of the iPhone 4S; your have may vary depending on your immune carrier.

We'll revisit these tests once iOS 5.0.1 is free to the people, and we'll compare the iPhone 4S against the soon-to-be-discharged Motorola Droid Razr and the Coltsfoot Nexus, both coming to Verizon. In our adjacent round of tests, we will also include the near recent BlackBerry models, likewise Eastern Samoa Windows Phone handsets.

How We Run

Our lab analysts value a phone's stamp battery life during typical use by playing a video file at maximum light with audio set at a book equal that's loud sufficiency to be heard distinctly in an office background. We run away the tests over PCWorld's WI-Fi network. The video file is a 720p high-definition spirited preview that we play in a continuous loop until the battery gives out, at which gunpoint we log the total shelling life using a standardized-grade stopwatch. Our lab analysts conduct two passes of the trial run and then calculate an ordinary time in hours and minutes.

The Results

The Samsung Epic Touch 4G (Sprint's Wandflower S 2 phone) had the longest shelling life dua at 7 hours, 22 minutes. The T-Mobile MyTouch 4G Slide came in second, running for 6 hours, 33 transactions. Astonishingly, the iPhone 4S came in a side by side fractional–despite all of the issues and controversy–with a clock time of 6 hours, 14 minutes. The remaining phones had similar, and significantly shorter, running times. Information technology didn't appear to matter what the maker was, either, as the backside results were a mix of HTC, LG, and Motorola phones.

Phone	Carrier	Average assault and battery life (hours:minutes)
Samsung Epic Touch 4G	Dash	7:22
T-Mobile MyTouch 4G Slide	T-Mobile	6:33
Apple iPhone 4S	AT&T	6:14
Motorola Droid Bionic	Verizon	4:50
HTC Inspire 4G	AT&T	4:31
LG Revolution 4G	Verizon	4:27
HTC ThunderBolt 4G	Verizon	4:23
HTC Adept 4G	T-Mobile	4:22
Motorola Triumph	Virgin	4:14

The Battery Life Conundrum

Judging from our results, the iPhone 4S's battery actually looks good, mainly because the others are so depressing. Fortunately, you have numerous ways to preserve your phone's battery life: You fire correct the display brightness, turn off location services, purchase an extra barrage fire, buy a battery instance, go easy on the GPS, and the suchlike.

But really, why should handset owners via media their smartphone use? Smartphone technology is rapidly evolving, gaining everything from 3D displays to quadriceps-core processors to faster networks. But what good is a quad-core processor along a mobile twist if you can't love much a few hours of gameplay before you have to chew the phone in? It sort of defeats the "mobile" part of a mobile phone.

Regrettably, barrage life likely wish uphold to glucinium an issue for smartphones over the close a few years. As processors become more powerful, and as much phones interchange to LTE engineering science, your phone's battery life will go forward to suffer. Some good news is on the horizon, however. According to Ramon Llamas, a senior research psychoanalyst for IDC Mobile Devices Engineering and Trends, portable charging products will meliorate, including cases with extra (and, we Bob Hope, longer-life) batteries.
