I’m a heavy user and let’s face it; our iPhone’s battery is inadequate. Take it from someone who has 2 chargers at home, a car charger, several iPhone USB cables and a portable external charger (called iPwr). I personally consider a 1 day battery life is a miracle. and I have looked everywhere for tips and tricks on how to extend its life… and I’d like to share my experience with you.

Turn Bluetooth Off: [Settings/General/Bluetooth]
Some people who use bluetooth headsets or have car kits, tend to forget to turn it off.

Turn Push E-Mail Off: [Settings/Fetch New Data/Push & Fetch]
And this is especially useful in areas of low signal. Turn Push off and set Fetch to Manually

Turn Wifi Off: [Settings/Wi-Fi]
Stop it from searching for networks all the time. Also turn off Ask to Join Networks.

Turn Equalizer Off: [Settings/iPod/EQ]
It requires a lot of processing power.

Closing Apps:
Press Home before pressing Sleep/Power button. You may not see it but the apps still run in the background… Especially GPS apps and Google Maps.

Turn 3G Off [Settings/General/Network/3G]
To keep connected to 3G, the iPhone constantly searches for it, especially when you’re NOT having 3G signal which drains battery… and they admit it under the slider setting.

Use Airplane Mode: [Settings/Airplane Mode]
If you’re in a building with no signal, conserve your battery by switching it on. Hunting for a network – and can’t have it- all this time is a power hungry process. This is true for all phones, not just the iPhone.

Lower Screen Brightness: [Settings/Brightness]
While it takes the joy out of screen, it’s a MAJOR power saver. Turn it to your least tolerable setting (the lower the better) and turn Auto Brightness off.

Turn Auto-Lock On: [Settings/General/Auto-Lock]
Set it to 1 minute (recommended). This ensures your iPhone conserves battery when it’s inactive.

Disable Location Services: [Settings/General/Location Services]
Turn it off when not required, like when not using Maps.

Turn Sounds Off: [Settings/Sound]
Alert sounds can consume some power. Although minimal, some recommend doing so.

Turn Vibrate Off: [Settings/Sound]
Turn it off for calls, and in games if possible.

Charge Cycle Every Month:
Charge it to 100% and drain it all the way before recharging. Go to www.apple.com/battery for more information.

Turn Notifications Off: [Settings/Notifications] iPhone OS 3.0 and later
Receiving push notifications all the time from apps, like Mail, drains battery.

Ideal Temperature:
for the iPhone battery to work efficiently, it needs to be in a temperature between 0 and 35 degrees Celsius. Don’t let your iPhone bath in the sun and don’t put it in your pocket for too long (wear a holster :) )

Turn GPRS/Edge/3G Data Off COMPLETELY (carrier data NOT wi-fi):
From my experience, this is a golden advice. My iPhone was driving me crazy. I have an alarm clock with AM/FM radio next to my bed. Once I jailbreak and install “my essential list” of apps and tweaks and put my iPhone to charge at night next to the alarm clock; it goes CRAZY with that distinct stuttering sound.

You know THAT sound when you put your phone next to any speakers while having a phone call? this is it, and it keeps going without end.. and it drove me and my wife insane and wished we could smash the phone, and I had to put it severals feet away from the clock. Obviously, since I’m not having calls, this is the result of an UNAUTHORIZED outcoming/incoming data exchange.

I tried to exclude which app does that by installing a firewall. But i removed it as it did harm more than good. And I had hefty amounts of data usage every month on my bill.. and may I add that I’m on the iPhone 1 GB plan !! (1 GB of data every month for free). I requested a detailed bill and to my surprise, i found the iPhone keeps sapping data all night for whatever evil purpose it has (not much every night, but multiply it by 30 nights).

I have surfed all over the net trying to find the simplest way to disable data with a single click. After much research, I came across my treasure chest: iphonenodata.com … You simply point Safari to the site, which only has one button for that sole purpose. It stops all outgoing data by installing a custom profile. When I want to reactivate the data, I simply remove the profile [Settings/General/Profiles] or -on rare occasions- re-spring to re-install the custom Vodafone APN profiler from unlockit.co.nz .

And finally.. the sound stopped and I had good night sleeps again. And for the first time, the iPhone was still having 4% of power after full 36 HOURS !! (I was using it in moderation while applying most of these tips: around 10 calls, only surfed 4 sites, and no games)

Here’s also the most powerful battery draining things to do:

1- Surfing the net (especially while on 3G/ with High Brightness)
2- Playing games (especially while leaving 3G/Wi-Fi On for online leaderboards or online multiplayer/ with High Brightness )
3- Listening to music (especially while playing your music in-game [iPhone OS 3.0 and later] )
4- GPS related apps (with High Brightness)

I hope everyone makes use of these tips :)

    @Moemen: Brilliant advice.
    I personally found Lower Screen Brightness: [Settings/Brightness] to be the best battery saver for me.
    You are kind of scaring me with the whole unauthorized data exchange issue, I wish that you had found out which app that was sending data back and forth.

    great tips , i found out that turning 3g off worked wonders for my battery life.

    @admin: Glad I could be of help :)

    The issue of iPhone security was on my mind since day 1. And it came in the spotlight when Jay Freeman (saurik; the creator of Cydia) released an app called PrivaCy, which aimed at stopping your iPhone from sending data to a specific establishment called Medialets ( if i recall correctly ) which collects iPhone usage patterns WITHOUT USER PERMISSION ! ( see more information inside the cydia package).

    Then, in February this year, modmyi.com posted this very important post on their forum:

    http://modmyi.com/forums/iphone-news/699423-beware-rogue-app.html

    I have the same advice for everyone: Be cautious… Be very cautious.

    @nihil: You’re welcome :)

    Actually I dont worry about it anymore. Although I do turn off wifi/bluetooth when not in use but I end up draining the battery daily anyway. So I just dont bother, I use it however I like all day and let it sleep in the charger at night. I rarely needed a charge outside either!

    And why the hell do you still need an iphone if you turn all these features off? Go and buy yourself a regular LE 200 phone from China with long battery life and bother us with stating the obvious. You shouldn’t have bought an iphone from the start….Unbelievable!!

    Dude, don’t get so hostile. Different people have bought/continue to buy iPhones for different reasons. I use nearly every single feature on my iPhone but it’s not constantly on, which makes it lasts about a day for me. I’m happy with that.

    Some people keep their iPhones on for longer periods of time but for a particular function or use and can benefit from prolonged battery life by disabling the features they don’t use.

    These tips aren’t applicable for everyone. They’re a collection of things for each individual iPhone user to pick and match from depending on their usage habits to help prolong battery life. As a matter of fact, I’m sure the tips provided by Moemen are applicable to all mobile phones, iPhone or not.

    i found something but, i don’t know .
    my friends & me keep telling that ipods & iphones when charged from computers stay longer than plugging to direct electricity.

    IS there anyone found the same thing or has an explanation ?
