My iPhone 5 just charged from 63% to 83% in 20 minutes
This was using the included charger and lightning cable – I can’t remember my 4s charging so quickly.
It’s risen another 4% in the last 4 minutes. Further testing is required

I can’t wait to see how fast the next iPad charges (I imagine Apple were not delighted with the ten hour charge time of the current model)

Update: I will keep posting unscientific observations here
1. Monday Oct 1st – at least an hour off the charger and still at 99%
2. Eight hours off the charger now and my battery is at 84%
3. Tuesday Oct 2nd – 17 hours off the charger now and we are only down to 70% (a lot of this had to do with not leaving the house, but it shows how good the battery life can be when the iPhone isn’t struggling to amplify its connection)
4. 40 minutes charging and we are up to 92%
5. Tuesday Oct 9th – Charge the client iPhone 4S today, 10 minutes to charge to 2%
6. Saturday Oct 13th – From 28% to 90% in 61 minutes

I haven’t given this much thought for a while, but my iPhone was on 5% today at 8:34pm.
I put it on charge and by 8:46pm it reported 30%. In the last 4minutes it has added another 6%
That’s pretty amazing – Lightning by name…
