iOS 5 has been out for a couple of weeks now and while it does have bugs, the most major one is definitely battery life. Users, specifically who have the iPhone 4S (but also the iPhone 4), have been claiming significantly reduced battery life and having the phone drain quite an amount of battery when in standby.

While nobody knows the root cause of the issue, there are certainly many things you can try to improve battery life on iOS 5 and the iPhone 4S/iPhone 4. Please keep in mind that not all of these solutions will work for everyone, so we recommend trying each one individually and looking for improvement.

Solution 1: Turn off sending diagnostic and usage data to Apple

The first possible solution that could solve your battery problems is turning off your device sending diagnostic and usage information to Apple. To do this, enter Settings>General>About>Diagnostics and Usage and clicking "Don't Send." Turning this off will have no impact on the features available on your device - it only stops Apple from receiving crash, performance, etc. reports.

Alongside this, we recommend turning off the location service for sending in diagnostic information. To do this, enter Settings>Location Services>System Services and turn off "Diagnostics and Usage."

Solution 2: Turn off unneeded location services, especially time zones

Another thing that may help you solve battery woes is to disable all or some of the location services on your device. To do this, enter Settings>Location Services. From there, you may want to disable any apps that are currently able to use your location for information. If you'd like to disable all Location Services, simply flip the switch at the top.

If you'd like to get more precise, go down to the bottom and select "System Services." From there, you can disable specific system-level services that are able to use your location for information. We recommend turning off "Diagnostics and Usage," "Location-based iAds," and "Setting Time Zone."

Solution 3: Turn off apps that are able to send notifications

Another source of battery drain, especially when your device is in standby, is apps that send notifications. These include Messages, Mail, Phone, etc. While you obviously would want to keep those on, games and other apps should be disabled from sending you notifications to improve performance and battery life.

To do this, enter Settings>Notifications and select which apps are able to send you notifications or not.

Solution 4: Disabling some or all of iCloud's services

A new feature in iOS 5 is iCloud, which keeps contacts, calendars, email, photos, etc. in sync between devices. While it is a very cool feature to have and use, it also takes up a good amount of battery life (for obvious reasons - constant checking and pushing of information).

To disable some or all of iCloud's services, enter Settings>iCloud. From there, you can turn off some services or all services. We recommend keeping backups on, as well as Find My iPhone (if you use it).

Solution 5: Disabling the obvious - Wi-Fi, Cellular Data, Bluetooth, etc.

This one has been a solution since the beginning. If you're not using services such as Wi-Fi or Bluetooth, we recommend turning them off. All of these things can be turned off in the Settings.
