The Ultimate iPhone iOS5 Battery Drain Solution Compilation:

Battery Saving Tips:

1: In Settings/Location Services/System Services - Turn "Setting Time Zone" to OFF. (Seriously recommended by a multitude of reputable sources!)

2: In Settings/Mail,Contacts,Calendars/Fetch New Data - Leave "Push" ON but set "Fetch" to "Every 30 minutes" or "Hourly" - then go to "Advanced" - Set "iCloud" to "Fetch" and any mail accounts that are non-urgent to "Fetch" instead of "Push".

3: In Settings/iCloud - (Optional Changes) - Turn "Mail" to OFF, "Calendars" to OFF, "Photo Stream" to OFF and make sure "Find My iPhone" is ON.

4: In Settings/General/Bluetooth - If you don't use "Bluetooth" then turn it OFF. (Minimal savings especially on the iPhone 4S with new bluetooth technology).

5: In Settings/Notifications - Look carefully through your list of "Apps" and open each one you don't need/want notifications for - Inside each "App" you will see a "Notifications Centre" option which should then be turned OFF.

6: Check the applications running on your phone by double tapping the "Home" button on your phone and holding your finger over the icons at the bottom till they shake to close any unnecessary applications that are open. Although it makes little difference to most people - its worth knowing how to do it.

Good Practices:

1: iCloud is designed to connect via WiFi every night at about 2:30am and sync / backup all your iPhone data. This is also suppose to work with the phone plugged into the charger. So charge your phone overnight - every night!

2: Once a month let you phone run the battery down to 1% then let it charge back up to 100% without any interruption. This will keep you phone battery in good shape. 

Myths:

1: Some people falsely think "Location Services" like "Find My Friends" or "Google Latitude" use a lot of power - They are very carefully engineered to use minimal power by turning on only when you change cellular base stations or if someone probes your location - It does NOT use the GPS permanently to check for a position change - it uses data that is already available from the cell network. You will find these application use less energy that your push email ever will!

2: A few believe that wiping your phone back to factory settings and restoring from the cloud will resolve battery problems - Well this is only the case in a few circumstances. People with permanently hot phones who have closed all running apps (after a full reboot too) may look into this but everyone else should not waste their time with this myth.

3: Many report that by turning your WiFi off will save power but generally this is not the case and often having good WiFi connectivity can in fact save power for a lot of people.

Advanced Battery Saving:

1: Try turning off sync over WiFi (If you use it) - It can only be deactivated from inside iTunes itself - not the phone.

Note: All tips are compiled from a multitude of reliable sources but are of course subject to opinion and may of course change in the future. If you have any useful information to add then by all means post a comment..

2: In General / Siri settings turn 'Raise to Speak' OFF - this should marginally help battery power as it will stop the iphone from leaving the IR sensor permanently on while the phone is active. This is done to detect the distance to your face. Actual battery savings is unconfirmed.
