Apple seems to admit a mistake, after receiving several complaints. Personally contact the owner of the Apple iPhone 4S, to find out the cause. Similarly, as reported by Cnet, Saturday (29/10/2011).
An Apple engineer, contact one of the user to install a monitoring program to find out why the battery life becomes shorter. Until now, Apple has not found a solution on the reduction in battery life.
Apple claims the iPhone 4S standby time 200 hours, one of iPhone owners said they saw a decrease of 10 percent every hour.
Previously it was reported that the site iLounge, conduct a review of the iPhone battery 4S. The results of that review reveals, battery life is better than the iPhone 4 iPhone 4S.
These results were different from Apple's claim that the iPhone battery 4S better than the previous generation iPhone.
