We’ve all gone through the dilemma of painful battery life on our Android devices. You root your device just install a custom ROM from one of the awesome developers in the community simply to get battery life from the optimized kernels. But the question that is asked time and time again is Why do we have to do this?
Cameron and I have both been testing out Windows Mobile Phone devices from HTC and Samsung and the battery life is simple incredible, which makes no sense at all!  Cameron is using the HTC Radar from T-Mobile and I have the Samsung Focus S from AT&T.  The Samsung Focus S has a 4.3″ Super AMOLED Plus Display and 1650 mAh so it compares closely to the high end Android devices we are all used to.
Windows Phone 7 Mobile is a complete multi-tasking operating system, just like Android.  I have my Samsung Focus S setup almost identically to my Android devices.  I’ve installed twitter, Facebook and 3 email accounts to name just a few.  I’ve made multiple phone calls, surfed the web and performed the same type of activity that I would on my android devices.
So why on earth do I get almost 3 days of battery life?  Cameron has had his phone turned on for almost 9 days without a charge, but this is with the phone not really being used.  Still amazing!
I’m asking any developers out there to try and explain why this is the case! Â Why are Windows Phone 7 Mobile devices getting much better battery life from their devices? Â Any kernel developers out there that have any experience with both technologies or just have some extra insight that might explain the differences! Â We’d love to hear from someone with the knowledge to really answer this question!
