The reason many think that Apple users are a cult is precisely because of the never-ending Apple apologists. Apple can do no wrong in their eyes.
The iPhone 5 and 5s battery sucks, no need to do Apple's damage control for them. Yes they seem to have slightly improved it in the 5s, though not nearly enough. Every phone out there has twice the capacity and lasts through the day. I've used a 5 and a 5s, I use my phone like all smartphones are meant to be used - a mini computer. If I wanted to just use my phone for talk time to make it last through the day I would have bought a cheap flip-phone.
Apple specifically markets this phone to be your personal assistant, to handle your music, to handle you life, yet when it is used that way it is dead mid-day. That's not acceptable, and no matter how much you optimize phone efficiency you can't beat the fact that the phone is lacking enough juice to fuel its power. Increasing the display area by nearly 40% while slapping minor increases to the battery cannot be made up for by optimization alone. Look at every other phone out there, the GS5, the MotoX, all these phones last much longer than a day and that's with the allegedly "horrible" android optimization.
Apple isn't magical, they can only go as far as physics will allow - something they don't have a lock on no matter how much others would like to apologize. I hope this report isn't true and we see some improvements to battery life, otherwise we will have another two years of the same complaints we've all seen with the 5 designs.
