I used to get pretty crappy battery life at my old job. Signal there was decent, it would show 3 bars but definitely was a tad slow and I didn't have wi-fi. Over the 8 hour day with checking e-mails and fairly normal usage my battery would be at 30% easily. Got a new job in a different I have been there for a month, I have wi-fi and full signal at all times. With the same usage I am now at around 80% when finished with the day. It's really weird. Oh and I have my brightness set around 85%.
 
I get 12-14 hours on my iPhone 4s before its docked. Usually when I do dock I have 30-40% remaining at least.

During day..

Listening to music for hour or two via Bluetooth headset. Sometimes this can be TuneIn Radio over 3G rather than music from my library.
A few photos taken, uploaded via 3G to Facebook, twitter and instagram
Facebook and Twitter checks
Facebook messaging friends a few times
A half to a dozen phone calls.
30-40 text messages
Updating of my calendar and reminders several times
Quick play on a game or two (10-15 minutes each)
Check my emails, push turned off, fetch turned on every 15 mins.
Brightness is at 75% with Auto Brightness turned on
Wifi is on when in wifi zone
3G is on




I have no issues with battery life.
 
When I first got my 4S, I had sub-par battery life. I was also unable to restore it as my Blackbook with my 3Gs backups was a few hours away. Three weeks later I was able to restore it from my backup by right clicking my iPhone in the left hand side and select restore from backup. This did not restore the 4S, just put my old data back on. Battery life improved emmensly. I am very sure the old setting that I manually set thoughout the various plists has increased by battery life. Lots of the settings in question are in the com.apple.Springboard.plist and where found via searching the Springboard binary for strings that looked like they'd set something. This was in December of 2007 on iOS 1.1.1. Most of those old hidden setting still work and change things. It's like changing a setting on a 10.4.11 Mac OS X installation via the terminal and the defaults command and still having it set after upgrading through 10.5, 10.6, and 10.7. One of these hidden settings set then is SBDisablePhoneAutoLaunch boolean set to true. This didn't do anything on an iPod Touch, but it worked wonders on my 3Gs and now my 4S.
 
I've found sitting in the office all day where there's practically NO signal, the phone will burn through the battery (doing nothing) by the end of the work day. If I go in and turn cell data OFF, the battery doesn't drop at all. These things searching for a signal all day can kill the battery in no time.
 
6 hours for me, once I almost got 7.

That's mostly tapatalk, messaging and phone. I'd like to screenshots of these 10 hour claims.
 
Wifi ON, 3G OFF. I listened to music a good part of 1 day while at work, and the 2nd day I sat home doing nothing.

FYI, you should make sure you don't reduce the light so much that your eyes have to strain. That sort of thing seems to worsen your vision. Malcolm X talked about it anecdotally in his biography.
I don't like searing my eyes. Most of my screens are all the way down or close to it. I offer wish my iMac could go even dimmer.
 
"iPhone has been plugged in since last full charge". That renders those hours void.

I was on a phone call, not gonna let it die.

Those arent my normal usage hours, but I get regular battery life of 1 day standby and about 8 hrs usage
 
I get better battery life out of my Verizon 4S than I did out of my AT&T 4S. Not sure if its radio related or not but guess it could be.

On average with my Verizon 4s:

-3 hours of talk time
-3 hours of light surfing (in addition to above...can't surf/talk at same time on Verizon)
-Latitude and Waze running in background all that time
-Screen brightness set at 3/4 of bar
-WiFi enabled
-Bluetooth not enabled (if I do, subtract 1.5 hours from above)

Maybe a game of Words with Friends or Drawsome thrown in there also but that's it.

I had bluetooth on watched a movie on Crackle for 2 hours, played a game for two hours and surfed the web for probably 4 hours with a phone call here and there and some text messages. I was purposely trying to kill it though so I could calibrate it, it seemed like forever. :p
 
On the 4s without listening to music I can't get anymore than this is this normal or is my phone defective I have tried and read all the tips and tricks on this issue. I have iCloud in my mail because I need it for find my iPhone but that is inactive and backup is off could this be a reason. Also I have emoji on my keyboard.

Find my iPhone option depends on the Location Service.
If your location Service is on, then it'll be working.
If your iCloud is disabled (OR) not signed in (on your iPhone Settings).
That won't affect it at all.

However, there're many things could waste your phone battery life.
I think the most thing can decrease your battery life, is network coverage. If you are going from place to another or your area has a poor coverage, that will affect your battery as well. It'll use more than you think.
(If you try to use your iPhone in Airplane or just remove the SIM card, you'll notice a big difference on your battery usage).

Although, adjusting the brightness and disabling most of the iPhone features won't help enough, unless you close the apps that working in the background.
You can do that by double hitting the Home button.


Also, if you reset all your settings by (Settings > General > Reset > Reset All Settings). Can make sometimes differences.


;)

Here's another one I took last night for you debunkers. Again, wasn't going to let my phone die like I wanted to until the call came in.

No "iphone has been plugged" here. And while the hours reported are different than what I posted previously, it's all in how the phone is used.

I agree completely. How you use the phone will determine battery life. However, these pictures are meaningless, because you could unplug your phone and let it sit on a desk for 10 hours and no one can tell what was done, based on these photos. In other words, a person could 'exhaggerate' their batteries capabilities. (Not saying anyone is doing this, just that it is possible.)

This image from my Galaxy S2 breaks it down, so no exhaggeration is possible. (I wish the iphone could display like this so you know what to minimize/turn off to save battery.) This is an LTE phone, but was only using 3g, so less drain. Granted this is also using a 2250mA aftermarket battery, whereas stock is only a 1850mA battery, and the display was set at 50% brightness.

I hope they figure out how to get at least a 2000mAh battery in the iPhone 5. The new Evo 4G LTE has one. But that isn't helping it get through customs I hear :eek:
 
Yes, 25% brightness is ridiculous. You won't see anything in daylight. He might be a vampire, though.

The first thing I did when I got an iPhone way back when was set the brightness to about 30%, with auto-brightness on.

In sunlight, I sometimes have to turn it up a bit manually but other than that I'm content with the auto brightness function.

Anyway. Can y'all beat this one?
