My Nexus 5 still runs for a week on battery. I believe Apple shipped low quality batteries as part of the planned obsolescence.
It's like committing two bugs. By themselves, they aren't a problem, but together, they open an NSA backdoor. If anyone is caught, they have plausible deniability.
Same here with Apple. They're so evil, they though ahead on how to avoid punishment for doing bad things. They'll skip off to the bank with bags of money while ignorant iPhone buyers just keep buying more iPhones instead of a quality device.
