I've seen multiple posts alluding to this. How does restoring to factory settings improve battery life versus upgrading from an older phone?

On the surface, this seems to be a classic placebo effect..

They were spouting this when the 4S came out, too. My 5 and four others who all restored from the cloud are all getting great battery life!

Sometimes this place does more harm than good.
 
Also note that I did not do the initial back up off icloud but off synced backup from itunes.

I believe others have stated here that apple reps said that icloud backup is fine as it doesn't carry over a bunch of the crap that the itunes back up does.
 
Setting the phone up as brand new has nothing to do with battery life. Last night I got 10 hours and 57 minutes usage, with 1 day and 4 hours of standby. I restored from my 4S backup and didn't start fresh.

This is my exact scenario as well. Backed up from my 4S, battery life seemed shorter at first, but eventually after a couple of days and cycles, I've been able to get slightly better battery life than my 4S.

Care to cite?

Exactly. This is basically just a superstition. It's an oft-repeated meme, an urban legend.

If your settings suck for battery life, they will still suck after restoring from iCloud. That is not the fault of having done an iCloud restore rather than set up as new.

These people also fail to realize their phone is brand new and the battery gauge hasn't had a chance to calibrate itself yet, not to mention the battery needs to see some electron movement before it starts operating at optimal efficiency.

In short -- these claims are nonsense. iCloud backup/restore exists for a reason.
 
My iPhone 5 battery sucked until...

I stopped playing around with my new gadget and starting using it like my old 4s
 
My iPhone 5 today died after 4 hours usage. My partner, who also has an iPhone 5, had 5 hours 30 usage and still had 41% battery left.

We both took photos, bit of browsing and that's about it.

Something odd I noticed this morning too, is my battery was at 98% rather than 100%. This is after 8 hours charge. Then as soon as I turned it on, I watched it switch to 97%.

What exactly is "setting up as new". Does this mean, don't restore from iCloud and literally download all your apps, rearrange your desktop, manually add phone numbers, mail accounts etc? That'd be a nightmare.
 
My battery life has been fine.

I didn't set it up and new. What I did was made sure my 4S was free of anything I didn't want to transfer over and updated to iOS6 and had a fresh backup. I restored my 5 from a clean iOS6 iCloud backup from my 4S.

I don't actively watch the battery. The phone charges overnight, and gets tossed on the charger when I'm in the car.

The one day I didn't charge it at all, I went to bet at about 30% battery life remaining. That was with about 3 hours usage and 14 hours standby.
 
I restored from a profile... and my battery was like my 4S (about a day's worth of usage) until I let it run dry completely. It took me 2 days.

Last night I charged it up from empty, and today it only went down 13% after about 12 hours. (Normal usage, for me.)

May be worth a shot to let it run all the way down once or twice so it can calibrate.

You think that is "fine"? That is NOT good battery life. This is a screen from my wife's 4S with iOS 5.....and this is with HEAVY usage (streaming radio while surfing web, over a hour+ of phone calls):

Anyone claiming "great Battery life!" needs to post a screenshot to prove it...."great" battery life to someone who's owned a droid is COMPLETELY DIFFERENT than someone who knows what iPhone's arre capable of (the standard)...

That would be because you don't know anything about software it would seem.
 
I'm going to go out on a limb and suggest anyone posting usage times of 10+ hours must have either been playing music for an hour or 2 with the screen off, or streamed music via BT.

I see no way this phone can get 10+ hours of actual usage, by actual I mean phone calls, Internet use, apps and camera, etc., anyone can add 2-3 hours to their usage number by playing music or streaming via BT.

I'm very satisfied getting 8 hours of actual usage on a charge. My 4s was lucky to break 5.
