Calibrate your batteries. I did and now my 4S gets about 1 hour per 10% of battery used.

A lot of people on here think it's pointless hocus pocus, but it worked for me and done it on all iPhones. I've done it on my GSII as well, it helps to have the battery readings correct. I.E. phone could be shutting down earlier when it really has life left b/c it's not read correctly. No different then calibrating on my Macbook Pro's where I saw a difference on both computers after doing so.
 
What's your screen brightness though?

50% with Auto set to on. I'm indoors mostly.

I leave wifi and bluetooth on all the time. Wifi is not set to ask though, it just auto joins known networks. Push is on, lots of notifications on, location services on for everything except some system services like setting time zone or traffic.

I admit I was one of those people. But I noticed something when I did it. It dropped like a rock to the 5-3% mark and then it took almost an hour to go from 3% to 1% and 1% lasted another 30-40 minutes. After that it shutdown, obviously, and then I waited about an hour before charging up to full. Since then it sips battery. I'm very pleased.
 
I'm also jailbroken and my battery is draining as fast as can be really.

Started class at 9 the other day and finished at 3.20 and the battery was at 35% from the 100% if was when I left home. All I did was half an hour of web browsing and 20 minutes of listening to music. Went to Wimbledon qualifying to watch the tennis after that and after about taking 50 pictures in 2 hours the battery died completely from the 30% it was when I got there.

Before the battery used to drain very fast when using it but now even in standby it is. :(
 
I get a full day of heavy usage with about 30% left over. I do keep brightness all the way up and push on. I am in an area with very strong Verizon signal.
 
I haven't used my iPhone for a while (this Nexus tops out at 2 hours of usage) but I think my average was 7 hours of moderately heavy usage. It can depend on several factors, particularly on cellular signal and activated antennas (Bluetooth, WiFi, etc.).
This quote is actually accurate.
2 hours of usage on a Galaxy Nexus is shockingly what the battery allows for. I'm talking about screen on time.
Standby time will always get you through a day. It's a non-issue now.
If you check your email 50 times in a day, but for two minutes each, you still will make it through a day...easily, even on a galaxy nexus. So the brightness level is the #1 thing that people need to mention before you even begin talking about appropriate battery life.

Screen on time is what you care about...and my general rule is that for the iphone, double what the competition's screen time is. The 3.5" screen helps alot with conserving the battery life, compared to 4.8" screens...although the iphone does have a smaller battery...

Our 4S and 3GS are jail-broken with a lot of apps and no difference in battery life vs stock iOS. You may have a corrupted app/file but a pain in the ass to check as you have to delete and add 1 by 1 but monitor each before adding the next to see if anything changes. Or could very well be a glitch in the OS, or you live in area that's creating heavy searching and draw on a bad signal.

I can tell you though the battery should last longer but not to expect 9 hours straight use browsing and video recording etc no matter what Apple says, it's just like their est life on the Macbook Pros etc, never gotten what they said even with everything turned off screen brightness way down and using a mouse instead of trackpad to save life (which usually ads at least 45+ min vs trackpad). Apples testing for life is biased "quirky" if you know what I mean ;) , Our replacement 4S is better on battery life than the 1st one but still not near my 4 or GSII in use or standby.

I would nearly halve any Galaxy SII or SIII's battery test results, b/c they cheat in my book. Their screen brightness, even at auto, which is what some tests rely on, is so dim as to be unusable. I read that the SII's max brightness is something like 330 nits, which is way less than an iphone's 525 nits. The Galaxy SII, at half brightness, of course is going to do pretty well...but crank up the SII to full, which would still be probably the iphone's 50% brightness, and you'll have more of a fair comparison. The only thing that would potentially negate my argument is that somehow an AMOLED 330 nit screen would "appear" as comfortably viewable as a 525 nit IPS screen, b/c of the increased contrast or something like that. I personally don't see it, but I have heard this argument raised before.
 
Ok I fixed it by erasing all settings. I now get 7-8 hours. Which seems ro be the norm. Now my question is my battery damaged by the period of intense drain from mid April when I first got it to today?
 
What apps are you running?

I have a jailbroken 64gb 4S from April and my brother has a 16gb non-JB from earlier this month. We both get around 4 hours 30min to 5 hours of battery life according to the Usage tab. Standby time didn't seem to affect the battery much, as I get the same amount of run time wether or not it has 1 minute of standby or 10 hours. It also didn't matter if I was shooting video most of those 5 hours or just texting and web browsing.

Does this sound normal? I know the 4S drains battery but this seems a little too fast.

=========================================================
That actually sounds about right, if you're gaming and using GPS, ya know. Something that is intense in CPU or cellular usage. GPS like gaming can make the 4S run a little hot. So that's not unusual, depending on the type of usage!!
 
Just some info. Read- this might be relevant for those who is getting 30 hours of usage!
I noticed that the usage meter and the standby meter resets at the 90 percent point when you charge your phone up to 90 percent and above.
So if you guys are getting weird timings for your usage, its probably because you guys don't usually charge up to 90 percent and above and continued to unplug and use the phone after your partial charge.
 
Can get around 7-9 hours of usage and 1+ day of standby.

Got Notifications (far from all apps) and LS (again, few apps only) on. Got it to fetch e-mail (2 accounts) every hour.
I'm on 3G like 6-7 hours per day.

My battery has been perfect since I bought the phone in October.

If that is done, the usage times will say "This iPhone has been plugged in since last full charge." rendering the long hours void. I don't do this, but rather only charge my 4S once a day.
 
If anyone is curious, here is the continuation of my data I posted earlier in the thread.

I got my 4S *two weeks ago. Here are some stats I've been taking over the couple weeks while at work (~7:00a-~3:30p):

Standby= 8h 22m, Usage= 4h 5m (9% battery left)
Standby= 8h 12m, Usage= 4h 5m (22% battery left)
Standby= 8h 3m, Usage= 3h 29m (37% battery left)
Standby= 8h 19m, Usage= 2h 46m (50% battery left)
Standby= 8h 15m, Usage= 4h 18m (27% battery left)
--continuation--
Standby= 8h 6m, Usage= 2h 15m (52% battery left)
Standby= 8h 19m, Usage= 2h 5m (56% battery left)
Standby= 8h 18m, Usage= 2h 12m (52% battery left)
Standby= 8h 21m, Usage= 2h 14m (49% battery left)

Let me know if anyone has any questions.

That seems good since if you total the amount of battery you have left with the amount you used it looks like it can average about 6-7 hours.

Mine is currently at 18% battery with 5 hours 30min of usage and 22 hours of standby looks like it will reach about 6 hours or more to the end. I think in finally getting normal usage hours after resetting all settings. However I am worried that the battery might have been worn more than it should in that period of intense discharge from when I bought the phone in mid April to now. You guys think the battery is okay? Since my phone is JBed is there anyway to check the health with an app?
 
My battery sucks. When using it for text and FB I can literally watch the battery drain. Just for those mentioned uses, I was down to 62% by 10 AM after leaving with 100% @ 7AM. No calls. I have to charge it before half the day is over.
 
Yay, yet another one of these silly battery threads where nobody can tell you of it's 'normal' or not becuase there are far too many variables.

Agree. Unless someone is with you 24/7, it's going to be difficult to give you an accurate assessment of your battery life.

----------

I could set my phone to Airplane, start a music loop, turn off the screen and get well over a day of usage.

This is exactly what some of these people posting in threads about astounding battery life are doing. Or something very close to this.
