Before I started the week of cycle charging I would lose like 4% battery life by just posting a reply on this site. My battery was literally dying after being off of the charger for 3 maybe 4 hours with very minimal usage.

Noticed day one the battery was draining faster then my iPhone4; I set iCloud to manual instead of push and it fixed the problem for me. Still have my corporate Exchange and personal Gmail on push. If you don't need push set it to manual. I do this for calendar subscriptsions; open the app and it checks for updates.
Also remember that anyone new to Siri like I am is going to have some data uploaded to Apple; I'm not sure how much or how long it takes but it is something else that will use data.

Only able to get 6 hour of usage after normal recovery on day 1 and DFU on day 2. Wifi seems to be okay, but as long as it is on LTE or 4G, the battery goes very quickly. Set up as new phone or recovery from old doesn't seem to make a difference.

I took me 2.5 hours to charge to 100%. I think the hardware is good if it takes a long time like 2.5 hours to charge. Our problems are likely because of IOS 6. Apple had this similar problem for those who first had 4S. The patch came out a month later.

I'm sure there will be a 6.1 (might save this for iPad4) or 6.0.1 update soonish.

yeaa you're right. that's exactly what i did to get a more reasonable battery life out of this thing. Some ppl are reporting the push email doesn't work so i m guessing the push is also behind the whole battery issue and it makes sense since push is one of the background processes that consumes alot of data. i wonder though, my ipad 2 is also on iOS 6 but it's working perfectly. i get push email on my ipad but not my iphone 5 even i had it turned on. If it is indeed a software problem then the effects should be identical across all devices that are currently running iOS 6. As far as i can tell my ipad 2 and 4S are working very well.

Kind of hard to compair the two sometimes; the iPad2 has a rock solid battery and if you only have the Wi-Fi version like me there is no cell chip using up power. I have to watch podcasts all day on my iPad to kill it and even then most days I still have 40~50% left when I plug it in.

I was thinking my battery life was doing better after making a bunch of adjustments but not so sure anymore. Charged phone to 100% and when it got down to 1%, I checked the usage stats and it showed:
Usage: 6 hrs 36 min
Standby: 21 hrs 6 min
Not sure where that 6 hours comes from since used it maybe 2 or so hours at best. Regardless, seems like should be getting better performance than this after using 99% of the charge.

I ran across the following at https://discussions.apple.com/thread/3526981?start=0&tstart=0 ,, written by 1AppleADayNoWa back in Nov. of 2011 in relation to the iPhone 4s battery. However, I found some of the information very relavent to our iPhone 5 discussion so I'm sharing it with you.
What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...
General info and specs
First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
... you didn't read it? loll Always remember this i.e. the definition of "usage":
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
Optimize your settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
- Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
- Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
- Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
- Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
- Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
- Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
- Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
- Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
- Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
- Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
Standby time: Up to 200 hours (0.5% per hour drain)
Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
Video playback: Up to 10 hours (10% per hour drain)
Audio playback: Up to 40 hours (2.5% per hour drain)
So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.
Apple's test methodology for claiming the specs:

I completely understand you are just trying to help but most of us have taken a fine tooth comb to our phones to try and get better battery life. Its to the point where I have disabled more features then on my 2 year old iphone 4 to try and get the same battery life with the 5. My favorite of those "tips" is part where it says to disable the phone (airplane mode) to get better battery life! I got a better tip why not shut off the phone completely it will last you weeks!!!

Here's my experience with iPhone 5 & iOS 6 battery life.
After restoring a backup from my iPhone 4 to iPhone 5, I noticed that battery life was unusually short. More particularly, I saw that in usage stats the Usage and Standby times were always very similar when in fact there should be much more Standby time than Usage time. After all, my iPhone was in sleep mode most of the time.
I tried pretty much all suggestions:
- Reset settings
- Delete all mail accounts
- Remove iCloud account
- Disable Facebook & Twitter
None of that worked for me.
The only thing that seemed to fix the usage stats and battery lift was restoring the iPhone as a new device ("Reset settings and delete all data"). So now, the Standby/Usage ratio makes much more sense and the battery life seems to be way better.
I just installed a handful of apps, iCloud & Photo Stream are enabled, LTE enabled. I didn't add any mail accounts yet. That will be the next thing I'll do and see if the problem returns.
That's it for now!

Have not changed my daily usage or settings. I am at 38% after 12.5 hours since I took of charge this AM. Not sure why there is such wide variances on the phone?
