Hi there everyone, I managed just over 7 hours usage, and a total of 25 hours standby, with 25% battery remaining on my iPhone 5S (Wifi plus 4G - Facebook, Whatsapp, instagram, snap chat, safari web browsing, lots of texts, about 30mins of calls; iCloud email on Push, 2 email accounts fetching every hour, background app refresh on for Snapchat, Find my Friends, and Weather). I have also been able to return figures of about 7 hours usage and 26 hours standby on an iPhone 5 (iCloud email on push, 3 other emails fetching every hour, twitter, photo taking, photo editing, Vine, Youtube, whatsapp, viber, texting, background app refresh on for Find my Friends and Weather). I had experimented a lot over the last few days and have worked out what to do. You do NOT need to turn off notifications - only for those apps you do not wish to use. Leave location services running, and once again - only disable for those that you do not require it. Otherwise, there is no harm in having apps you use notify you and use your location if it requires it. Same goes for Background App Refresh (there aren't many apps that do background refreshing as yet). Here is my guide on better battery life: 1. If you are backing up to iCloud, Go to Settings > iCloud > Storage & Backup > Manage Storage - Under Backups you should have your iPhone listed. Tap on it, then "Delete backup". This is important as it clears data that could be causing bugs. 2. Connect your phone to iTunes if such a facility is available to you via USB cable. Press on the menubar on your computer for iTunes "view", "show sidebar". Right click your device, and hit "transfer purchases". This will sync all your apps to your computer. 3. If you're still connected to iTunes, on the summary page of your phone, hit "Restore" (If you have iCloud on your device activated, make sure to go to the Find my iPhone settings and turn it off so that your phone can be restored). This will download the software (if it hasn't already) and restore your phone. If you are not connected to iTunes, on your phone go to Settings > General > Reset > Erase all content and settings. WARNING : You will lose your data, but will have your contacts/reminders/notes/photos (via photo stream) backed up thanks to iCloud. 4. If connected to iTunes, select "Setup as new iPhone". If you are not connected to iTunes, your phone will appear at the "Hello" screen once resetting. 5. Swipe through all the questions - Enable location services, Use Siri, enter your iCloud details, use find my iPhone, etc. 6. if you are connected to iTunes, You can then click on "apps" via the tabs in iTunes and click on "install" for each app you wish to install. Then hit sync. Your apps will be reinstalled but without any backed up data. If you haven't used iTunes, Just go to the App Store, Tap on Updates, then on Purchases, and re-download Apps from here. 7. You can let your phone backup to iCloud now - that is ok. This is because all the buggy information stored in the apps has now been removed, and your phone will behave much much better. 8. Fully charge your phone. Even when it reaches 100%, leave it for an extra 10 minutes. 9. Lastly, if you use Facebook, every time you use it, make sure to double tap the home button and close it by swiping up. You will still receive notifications, however this seems to cause battery drain in the background (despite having no option in Background App Refresh). I shall conduct a battery test with this running without closing and return with my results. 10. Congratulations. Fingers crossed my guide results in helping you and increasing your battery life to respectable levels once again. Let me know how it goes. So far I have done this to my 5S, a friend's 4S, and 3 other iPhone 5's with flawless results. This guide is for those on iOS 7 who would like to try an alternative approach to gain better battery life. Hope it helps if you give it a go Also, for those that might not know: "Usage" refers to the total time the phone is active (including doing things in the background when you're not playing with it). "Standby" refers to the total time the phone has been inactive AND also the usage time - that is, the total time the phone has been running.
