I am sorry but I agree with yout that your battery life on your iPhone 4s does not look good at all! iPhone 4 would do for example sooooo much better!
enx23,
the iPhone 4 and the iPhone 4S do not have the same battery specification. this info was provided by Apple before the phone was released and is currently stated on the product pages of the product. in my experience with hundreds of users now, the 4 typically gives users 1.5 days (heavy use) to 3 days (light use) wheras the 4S typically gives users 1 day (heavy use) to 2 days (light use) for normal operating phones. again, this mostly is the result of reduced standby time in the spec by 33% (i.e. from 300 hrs to 200 hrs). there was also a reduction of 10% in wifi data usage (i.e. from 10 hrs to 9 hrs).
Also you should consider that in time the battery will wear down and this means that provably in one or two years your battery of iPhone 4s will not last until the evening if the same day!!!
specifications for almost all products are given for new. anything beyond that... warranties, etc will have all sort of exceptions, expected wear, etc. there too many variables in usage patterns to determine where that battery will be in 2 years for each individual. the main thing we want to determine is if the phone is performing to specifications new or within a reasonable amount of time. if it is not, is it software issue or a real hardware issue. in my experience, less than 30% of buyers are having battery issues that are not with in spec. of that 30% with the issue, less than 10% of those have a "real" hardware/battery problem according to spec. the majority of the battery issues are caused by old backups, corrupt settings, corrupt mail or roque apps that can be addressed through various methods. note, that i have seen these issues with every iPhone release except for the original.
