As I wrote a few days ago, my iPhone’s battery life is terrible. I did everything I could think of to maximize it but it’s still not enough to get me through a full day without charging it.

The only good thing that comes out of that is it helped me put up together a list of 16 things you can do to increase your iPhone battery life.

Apply all or some of these tips and your battery life should get better. Note that this article is inspired by Apple’s website.

  • Keep your iPhone off the heat. It works best from 32° to 95° F
  • Update your iPhone with the latest firmware (unless you’re a jailbreaker)
  • Turn off wifi if you’re not using it (Settings > Wi-Fi and set Wi-Fi to Off)
  • Turn off 3G if you don’t need it (Settings > General > Network and set Enable 3G to Off)
  • Turn off song EQualizer (Settings > iPod > EQ and tap Off)
  • Turn off Bluetooth (Settings > General > Bluetooth and set Bluetooth to Off)
  • Turn off Push Notifications (Settings > Notifications and set Notifications to Off)
  • Turn off Location Services (Settings > General > and Location Services to Off)
  • Turn off Push Email (Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off)
  • Fetch new data manually (Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually)
  • Don’t check too many email accounts (Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off)
  • Auto-adjust Brightness (Settings > Brightness and set Auto-Brightness to On)
  • Don’t play too much games
  • Go through a full charge cycle each month (charge the battery to 100% and completely run it down)
  • Set Auto-Lock for the screen to 1 minute (Settings > General > Auto-Lock > 1 minute)
  • Turn off Vibrate (Settings > Sounds and set Vibrate to off)

I understand it’s quite impossible to follow all these tips at once but depending on the situation, you can make these simple adjustments to your iPhone and it will undoubtedly increase its battery life.

If you have more tips on how to improve the iPhone battery life, feel free to share in the comments or in the forum.

    I have CONCRETE evidence OS 3.0 is the problem regardless of push and all features deactivated.
    When my 2g iphone was running 3.0, my battery would drain at a rate of % 5-7 percent per hour in standby mode. I spent a whole day no either talking or texting and after 20 hours my battery was almost depleted. Again, I had Push, Location, and continously shutting MobileMail down from sysinfo pro ’cause it would run on the background when contacts are called up (WTF has MobileMail to do with phone contacts anyway?).

    I was so pissed that I went back to 2.2.1 using iTunes 7.7 as it doesn’t mess with baseband on the 2g which stayed the same after 3.0 upgrade so I could downgrade with no warnings at all.

    Now with 2.2.1 I’m having a discharge rate of % 1-2 per hour and I charge the phone every -almost- 3 days.

    Wish there was an app that would set all those functions with the tap of one icon.

    In short turn off your iPhone. Function = battery life.

  • I use the 2G 16GB. It´s true, the battery live is not overwhelming- so thanx for this information. My solution: I reload my iphone with every FIRST coffee of the day 😉

  • iPhoNerd

    If we need to do all these steps why would I need an iPhone? Lol. I can settle with an ordinary cell phone. Wake up apple!!!!

  • Yann

    @Shug1. There’s one ! Sbsettings. Works great, available with jailbroken phone

  • Ra

    Turning half ur iPhone features to get more battery does not solve the problem. If so get another phone. Which is what am planning to do.

    In so manytime my iPhone runs out of charge when I really need it. Specially during long trips where you can’t charge :s. A reasonabily good battery life is essential for any mobile. And it’s more important the all other added features.

    Can apps run in the background and sap battery life? Things to look for if so?

  • Polemicist

    Let’s be honest… Turning everything off is a waste of one of the best phones you could ever play with. Yeah Firmware 3.0 has some issues we all know that. Hell they turned on a great big heap of features did you all think that was going to leave your battery alone? And then you have all the dudes bitching about the battery not being removable. Again who cares.

    Use one of them. If you want buy two and your set for ages. And then feel free to turn on every damn feature on your phone. 🙂

    I don’t own one cause I just plug my phone into my laptop for emergency power or plug it in at work during the day. I probably will buy one. I saw the ad for these on this very website. I’ve heard they are good. If someone knows something better than please feel free to say so. 🙂

    Don’t kill a great phone by turning it off.

  • Franchute

    WTF? Turn off your phone. That will increase battery life. Should drain in about 1 week.

    I’m actually getting very decent battery by turning off WiFi, location services, bluetooth and 3G…I turn them on whenever I wanna use them and my iPhone 3G runs consistently for approx 3 days without need for a recharge. One problem though, I wonder if anyone else has hit this…the phone dies out at 10% battery, so, my actual battery time is from 100% to 10%! Any ideas how i can use the last 10%, maybe I can push it to 4 days 😉

    • Ovrdrvn

      Zeeshan (or others) does turning off bluetooth, wifi and location if they are not being used actually save battery life? I have the search for wifi off but turning the antenna off saves? Same with others?

    I have to second Polemecist’s post. I got the Mophie Juice Pack Air and I can at least guarantee that I’ll have a charge through the day. And if I keep the Mophie charged, in theory I’ll double the life of the iPhone’s battery.

    Still, it’s kind of an expensive solution, and hopefully Apple will fix the firmware.

  • Steven

    I got my 3gs 1 month ago. The battery is not better than my old 2g (2 years old). It run faster but battery doesn’t last a day. I didn’t change my style. I hope apple wil make better battery for next one

  • Joseph

    Basically… do NOT use your iphone for any of the features that you probaly bought it for and you will get GREAT battery life. I love my iPhone but if I have to shut down the wireless, push notification and all those features then what is the point of even having it? Here is the solution, get a cheap car charger from ebay (i got mine for 3$) and get in the habit of giving it a little juice every now and then.

    Actually, turning off the 3G helps out alot. I find that I can still surf the net at a decent speed and it really improves the life but I still say you should just get a car charger and give it a little juice here and there. The IPhone charges REALLY fast and even a quick 15-20min charge here and there will really help you get through the day

  • I have the Mophie Juice Pack Air & I love it! I can go all day with battery life, plus have extra to play with. Best $$ I spent since I bought the iPhone, especially since my upgrade isn’t until October this year, so I had to do something, lol.

  • Carol

    I just wanna question about the auto brightness thing. When it’s set to automatic, doesn’t it consume more battery life?

  • It is difficult to design better battery, but thanks for the great tips.

  • Bob

    how do i turn off the aps running in the backround ???

    • DB04953

      Double click the Home button. Running apps show at the bottom. Hold an icon down till they all begin to shake and have “x’s” on them. Press on the “x” to close an app.

      Note that this function (double click home button) also reveals a settings area for screen orientation lock, etc. just swipe your finger across the running app icons left to right to reveal those controls.)
