Wow.
4 million suckers got dragged into purchasing the same phone 2 years running.
Only to find that battery has gone backwards.
Most of you geniuses dont realise that battery should get better with performance gains.
Take intel for example.
Every generation the power usage goes down with performance going up.
Basically the A5 is just a clocked up CPU with a better GPU.
iPhone 4S = Cash Cow.
Lower costs and higher margins make stock markets very happy.
My iPhone 4 has gotten faster with IOS 5 so i doubt the performance gap everyone is seeing is all to do with the A5.
Ill wait for the iPhone 5 when a real successor comes out that warrants a £500 upgrade
You keep doing everything you have to to validate your decision to wait another 12 months for a new phone.....the rest of us will enjoy the 4S
The battery is a little worse but its seemed to get better as time went on as I charge and run it down. Now to the point it's only about 10% less then my 4 by the end of the day.
