iPhone Battery Life and iPhone Battery Charging Tips – Extend iPhone Battery Life

If you’ve bought an iPhone, you’ve probably realized that its got a very solid battery life for all of the features that it offers. Though I have heard some complaints of faulty batteries, most stories of battery life have been very positive. If you need a little help making your battery last a little bit longer, here are a few tips to help you extend the battery life of your iPhone.

  1. Turn of Bluetooth – if you’re not using the geeky little headset to make phone calls, you don’t need bluetooth enabled. No need to have your iPhone search endlessly for bluetooth devices if you’re not planning on using any.
  2. Use the Auto-Lock Setting – I’ve got mine turned to 1 minute. This means that after 1 minute of inactivity, my iPhone will power itself down (same as pressing the power/lock button on the upper right of the phone). This is probably one of the biggest battery savers, as the screen will not remain lit while the phone is not in use.
  3. Get yourself in the habit if locking your iPhone when you’re done using it – After you make a call, send an email, check your stocks, or do whatever else you may need to do, click the lock button at the upper right hand side of the phone. Don’t wait for it to power the screen off on its own. Turn it off as soon as you’re done using it for the task at hand.
  4. Turn off the WiFi radio – When you’re not connected to a WiFi network; i.e. when you’re not at home, at a coffee shop, or some other place where you know that you’ll have WiFi access; turn off the WiFi radio on the iPhone. This will help to increase battery life.
  5. Drain the battery completely prior to charging – This is a good practice for anything with rechargeable batteries. I used to employ this tactic heavily when I was into racing R/C cars, but that’s an entirely different story. Learn your phone and how long the battery lasts FOR YOU and charge it accordingly. I can typically go 2 fulls days without a charge. The battery lasts just fine for me to do the following 2 days in a row without a charge:
    1. Listen to 1-2 hours of music (typically on shuffle with the screen off)
    2. Make calls (typically 15-60 minutes… I’m not a big talker)
    3. Check emails approximately 10 times through the day
    4. Send between 5-25 emails… this depends on how busy I am while not at work.
    5. Check stocks 3 times per day
    6. Check weather in the morning and evening
    7. Send 10-20 text messages

    My iPhone battery will last about 2 days while doing the above tasks. On the second day, the battery will fall into the red zone between 4-6pm and when I return it to the cradle in the evening, it will usually only have about 10% of its life remaining. I know this isn’t a “complete battery drain”, but it’s pretty close.

I’ve been using these tips listed above and have been getting great life from my iPhone battery. I’d love to hear if anyone out there has any additional suggestions that can be added to the list.

  1. Great advice. I’ve found the radios (bluetooth or wifi) to be big power sucks on many devices. For people who don’t use those features continuously, turning them off will be a big power saver.

  2. DO NOT drain your battery completely prior to charging the iPhone battery. Go to Apple’s website and read about Lithium polymer batteries and Apple’s recommendations to extend battery life. In the old NiCad and NiMetal Hydride battery days, the idea of draining the battery is correct. These batteries developed memory. A lithium polymer battery is a different animal. It needs to have its electrons moving. Completely draining a lithium polymer battery can actually shorten its battery life.

  3. Frank: Apple actually does say to completely drain your battery on their website. [ http://www.apple.com/batteries/iphone.html ] To quote: “For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).”

  4. I think that’s poor phrasing in that instance, because as apple says (http://www.apple.com/batteries/):

    “A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean a single charge. For instance, you could listen to your iPod for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle.”

    I’ve heard a bunch of times that for lithium batteries, not to drain them for the above stated reason, and I’m not sure what to make of this but I’m leaning toward Frank’s idea given what we’ve read from apple

  5. Lastly for people not in a 3G area all the time. Turn off 3G.

    This will add alot of life to the battery…you just need to remember to turn it back on when in a 3G area.

    I do this because I live in a remote area of Germany. While most of the more populated places are 3G. My home town isnt.

  6. Hi guys,
    My battery lasts around 6/7 hours, in this time I will.

    Have wifi switched on, but only being connected 45% of the time.

    Have 3G switched on, however my area is very choppy for coverage, (Manchester, UK) (o2)

    Check for email hourly on;
    Gmail- IMAP
    Google- Exchange contacs and calendars

    I send approx 6 emails

    About 4 texts

    Call 10 max

    Surf the net for about an hour or two

    Use palringo (instant messenger) (app store)

    Do you think my battery is defective for a change every 4/5/6 hours,


  7. Sme hppens to me 4-6 hrs max….
    I have to charge it all the time.
    It’s a new O2 UK phone….

    Battery SUCKssssss big time.

    I might go back to nokia…. :-)

  8. I think we should all ring apple and complain before the warranty runs out!!! Then we can have new batterys!


  9. This is absolutely retarded..
    Apple recommends turning off bluetooth, wifi, location services, blah, blah blah..
    If you have to do this, what’s the point of using the stupid phone?
    I don’t even use the phone features of my iphone and the battery lasts less than a day, with wifi, bluetooth turned off.
    I also have a blackberry bold with all of these features enabled and I use the bb as a phone. It lasts at least 2 full days with heavy usage.

    What good is the iphone if you have to carry a charger with you everywhere you go?

    Plus, the novelty of the touch screen is wearing off. It is cool, but really isn’t useful for typing messages and doing regular functions of a smart phone. The only benefit right now is the web browser and some apps that are available, but some of these apps drain the battery too.

  10. I have problem, this is first time i’m use iphone.starting i’m charge about 8 hours after that i used no problem untill battery weak and i charged the phone but nothing appear on my display phone, only label apple the with colour only ,its my battery in condition charging or not.

  11. Answer aris it better you charge your iPhone with wall after complete run down .. It won’t not charge in USB when your phone have no battery.. IPhone baterry it good no as people say that bad..

  12. Just a suggestion. I find that all the above features do help to keep the battery running longer, but the main drain i find is the brightness factor. I turn mine all the way down practically to where its just bright enough to see what your doing. This will help a lot.

  13. Apple DOES suggest a full charge and once a month a complete drain.

    Use iPhone Regularly

    For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

  14. Back from first road trip with iPhone. Great device (could leave laptop at home), but its battery does not even “safely” last one day. And the phone/mailer/messenger are THE most important productivity applications when on the road. Dead phone – no business!

    My BBerry just did not “feel” as vulnerable. For the iPhone to really work for road warriors, additional (external) battery back is badly needed. One more thing to lug around… :-(
    Or, I might just have an SEMC phone charged and move the SIM card over in dire straits. That phone can handle months if stored.
