iPhone 4S Battery Life: How Does it Stack Up Against Other Smartphones?

If there's one hot issue over the past weeks, it is the iPhone 4S's battery drain problem, a fact that has been admitted by the Cupertino company itself. Based on the fix that was provided previously, it seems that the iOS 5's location services poses to be the main culprit behind the seemingly degraded battery life of the new iPhone. Upon acknowledgement of the problem, Apple was quick to issue a firmware update in the form of iOS 5.0.1 which is now currently on its second beta. Now you are probably wondering how the iPhone 4S fares against other smartphone offering in the market in terms of battery life.

Battery Life
When the HTC ThunderBolt and Samsung Charge (both 4G capable devices) were released earlier this year, consumers reported poor battery life span. Well the folks over at PCWorld conducted a simple test in order to evaluate the top smartphones in the market with regards to their battery life. The test was conducted by playing a high definition video file on loop at its maximum brightness and with the audio set to the highest as well. That's until the battery dies out followed by the tester logging the total time. Check out the results in the chart below:
Smartphone Battery Life Test Results
Considering the recent outcry regarding the iPhone 4S's battery drain issue, one would think that it will rank lower in the test. But surprisingly it managed to rank in third place with a time of 6 hours and 14 minutes. Ranking in first place is Samsung's Epic Touch 4G, Sprint’s version of Galaxy S II phone with 7 hours and 22 minutes time. It is followed by T-Mobile's MyTouch 4G Slide with a time of 6 hours and 33 minutes. It is worth noting that the devices below the iPhone 4S have significantly lesser time managing only more than 4 hours.

PC World claims that this is merely a sample comparison and not the end all be all of battery life tests. This is because there are other factors to consider that may affect the results such as the carrier of the device. It is also worth noting that while the iPhone 4S did rank in 3rd place, majority of other devices are actually 4G capable which is of course a factor that contributes to battery drain.

It seems that in this day and age, battery life will most likely be an issue for modern smartphones considering just how advanced their features are. It’s frustrating that smartphone manufacturers continue to work on upgrading their hardware and supporting the latest network technology but somehow neglect to optimize their batteries.
