Hello all, I Couldn't find a guide like this on Macrumours; and every other website I look at only have "simple" guides. I made this for power users and normal users a-like. If you see some information below that is inaccurate or want to help add new info, please leave a comment below and i'll amend this thread. Legend: Highly Recommended, Recommended, Not Recommended, Not Proven. Lower your brightness Info: Helps save battery a LOT. I recommend 30-40% if you want to still have a bright device, or you could use Auto-Brightness. Direction: Settings>Brightness Disable iCloud Info: Helps Battery, Saves wasted data and phone usage. Direction: Settings>iCloud Disable Bluetooth Info: If you don't need or use it, why keep it enabled? Direction: Settings>General>Bluetooth Disable 3G and/or WIFI Info: If you don't use either of these then a disable would do huge wonders for battery life. Direction: Settings>General>Network>Disable 3G Perform a full battery drain Info: There has been a lot of proof showing that i you fully drain the battery every month it lasts longer. Direction: Wait until your iDevice dies and then fully charge it. Close apps properly Info: This should not need explaining. Direction: Double tap home button, hold an app and press x at the top. Disable Notifications Info: Slightly helps with battery, somewhat recommended. Direction: Settings>Notifications Disable Push Notifications Info: Confirmed to help a fair amount with battery, fetch every 15mins is acceptable or just manual so you see them when you open the mail app. Direction: Settings>Mail,etc>Fetch New Data> Auto Look sooner Info: Change Auto-Lock to 1 minute - iDevice's screen sucks out a lot of battery juice. Direction: Settings>General>Auto-Lock Disable Siri Info: Siri has been known to make battery life worse. Disabling Siri could remove personal Siri info. Direction: Settings>General>Siri Disable Location Services Info: Disabling System services are recommended, other services arent as recommended because they are only active when in use. Direction: Settings>General>Location Services Disable Twitter. Info: Known to drain battery and use up data, scroll to the bottom to disable it. Direction: Settings>Twitter> Restricting Ping Info: Its reported this uses up a fair amount of unjustifiable battery. Direction: Settings>General> Restrictions Disable Diagnostics. Info: This "service" sends data to apple eating up your data and some battery along the way. Direction: Settings>General>About>Diagnostics & Usage Disable Spotlight Info: Not very noticeable difference and not entirely recommended. Direction: Settings>General>Spotlight Search>Disable all. Set Time zones Manually Info: Save your iDevice from having to constantly using GPS. Direction: Settings>General>Location Services>System Services Disable EQ Info: Not sure if this myth is true, but I added it just incase. Direction: Settings>Music>EQ Turn off Vibration Info: Only useful if you get tons of calls, texts, etc. Direction: Settings>Sounds Turn off Keyboard clicks Info: Only useful if you type a lot. Not very useful. Direction: Settings>Sounds Use Airplane mode Info: Have no phone service? This will make your iDevice last for ages. Direction: Settings>Airplane Mode Restore Info: Maybe there is something wrong you cannot find, a restore could help. Direction: MAC/PC>Itunes>Restore. Reset Network Direction: Settings>Reset >Reset Network Settings Disable Ask to Join Networks Direction: Settings>WIFI Networks Jailbreak Tips I don't plan on adding any tips relating to Jailbreaking as I realise that most "end users" wont use jailbreak. I will however mention that disabling launch daemons and deleting unused languages helps. I plan to keep this thread alive for at least the next 2 gens of iDevices. Of-course you can feel free to post this information on other forums and websites.
