Sorry my comment had nothing to do with impressing anyone. It was a relational statement.
In addition to NORAD i was a Software PM of an Aegis Weapons Basellne. Point being NORAD, Aegis and many other systems in the world, defense or not, are large and complicated. Think those litle devices are more complicated than a fighter jet? Look at the Apple products as mini-systems. All of these have tens of millions, even hundreds of millions, of lines of code if not more. It's all very complicated. But like real CMMi processes to Level 5 teach - never get bigger than you can test - often. This battery issue was not some complicated issue where a minimal set of users were hitting a complicated set of buttons. As such no matter how complicated it is a VERY EASY thing to test got by. if you think otherwise or if Apple thinks otherwise that would be foolish. Have you seen the problems RIM is having? How do you think that started out? Think Apple products are more complicated by a factor? Even twice as much? Again your testing and QA and your ability to test, track defect density, regression test and know exactly what is going on has to be as good or better than the technology in the baseline cose or eventually you will fail. I wonder if they used Agile? Isn't it's hallmark quality over schedule and cost?
I can point to all kinds of industries that did complicated groundbreaking things that lost it. What do you think the root causes in common were? Arrogance was surely one of them. As was complacency, sloppiness - something less than Six Sigma quality.

Nov 13, 2011 8:04 PMby Tefimom,I too have seen a significant increase in battery drain since updating to iOS 5.0.1! I have a brand new iPhone 4 and had no problems with the battery before the update. After the update I can literally just watch it go down. I just spent less than 10 minutes checking weather and Facebook and lost 8%!! This is a major concern for me since I am a single mother with 2 special needs kids and a full time student, I need a phone I can depend on to work when I am away from my kids! This is insane! I never thought I would regreat buying an iPhone, but I am starting to!

be sure to go through these steps:
1. Reset all settings (settings-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there)
3. Turn off system location services timezone and iAd
4. Fully discharge battery
5. Fully recharge battery
In my experience this improves the Standby battery drain issue significantly. It reduces drain from 2-4% or more per hr to 0.5% or less. It worked for many users now. Check my thread here on the process, settings, etc

Nov 13, 2011 10:31 PMby Stony667,Last night I restored my iphone 4s to a new iPhone and put back everything manually and not through a backup copy. Had hoped that this would work but unfortunately after a night stand is already 20% since. I see a doctor to monitor the battery mobile phone 8 hours and 51 min was used. It has been corrupted so that at night or something got on the phone. Could have something to do with the SIM card or something that every time he is working with network? Another additional problem after updating to 5.01 Ios is Imessage sometimes more work than just nion should I switch to a Imessage times on and off and it works again. Since the update also get a message once a day invalid SIM card. Someone who is known for these things coming?

Nov 14, 2011 12:14 AMby virgilfromcolorado springs,A hard rest is a factory rest (restoring your iPhone as it was when you bought it). I have never had a battery issue with any iOS. I simply close all open apps clear cookies and data then clear history. Then power down for approx 30 sec. I do this every day and my battery life lasts 2.5x more than my wife ,son and ,daughter. I'm a heavy iPhone user. Now they follow what I do and they now enjoy long battery life. I also allow my phone twice a month run the battery all the way dead without charging.Then charge full.
