* These battery issues appear to be related to iOS5 itself, the version which introduces Android-like background notifications and widgets. Everybody knows these background tasks drain more battery, but this implementation was touted as being better: “Multi-tasking done right”.
* The A5 processor (the marketing name for Apple’s own dual-core Cortex A9 chip), is already de-clocked at 800mhz (vs 1ghz in the iPad2), in order to reduce battery consumption.
* In their defence, battery-life concerns are often extremely difficult to diagnose, without a system log dump or background system monitoring apps (but you’ll need to jailbreak for that).
* The 4S has an official lower rated 3G usage time than the 4, despite a slightly bigger .05wh battery. Presumably due to it’s dual-core architecture, and thirsty GPU (it’s PowerVR SGX 543 is listed in Wiki as being 65nm, where the SGX 535 is a 45nm chip).
* As we know, extended or spare batteries, alternative OS’s or alternative handset models are not an option.
* Job’s goal for end to end integration of the entire ecosystem has always been to ensure minute control of all components and their functions for a better user experience (see the turtle-paced evolution of the iPhone through the years). But, ONLY if it’s executed to perfection, which is where Scott Forstall needs to follow-through.
* I contend that for all their depth of employees, huge cash hoard and results-driven attrition-based corporate culture, that consistently, Apple has proven to be technically incompetent (especially in software/OS), a somewhat scary thought as they enter the realm of cloud computing. The problem for many end-users of course, is that they are unable to use an alternative.
