@frankbustos  - Thanks for the update and I was happy to help.

resetting wireless worked. thanks!

I've seen battery improvement after a simple phone reboot (a symptom you might notice is the phone is often unusually warm, even without much use).

To reboot, hold the Home button and Standby button until you see the Apple Logo, then release.

Is it jailbroken?

The link itself was not content-free, but there was no proposed solution. Without the link, the post would not have helped much or at all. That is our test. The rest of the posts are posting actual ideas. Thanks.

duncanb's link to that zdnet article was not content-free; the content was in the picture slideshow, not the text.

duncanb - your post was essentially a content-free link. Please post solutions in your own words in future.

A reminder to everyone about blind links :

One thing that works well on my iPhone 4s is to change email from push (always checking) to check manually (on request) or every half hour (and you can still check manually).

I went from 3 hours to most all day.

If you charge it fully and let it discharge fully so that it turns off before recharging it, does it hold its charge for longer?

Have you backed up your phone, reset it and reinstalled the latest iOS via a PC?  If not, I would recommend it.

Turn off all unwanted background applications as they can drain the battery Settings> General> Background App Refresh.

Have you got any Exchange Activesync accounts setup on the phone?  If you have, set the sync to manual not Push and don't check your mail - does that improve life?

it is hard to find out exact root cause. it prefer  to reduce power consumption for  whole system improvement
