iPhone Battery Life


iPhone Battery life. You're probably wondering how long this wonder device lasts. So far I'm going to rate this as fair.. I'm sure that there were a few things that Apple could have done to get a better and longer battery life but the quality would have suffered massively. For example the sharp screen could have used organic screens... making it less thick and more energy efficient... however the organics are not quite where LCD needs to be and not only that reading an organic screen in direct sun would prove to be useless.

I can see my screen just fine in the sun light! It works great in all light and I thank Apple for making the auto adjustment! It's awesome!

Battery life is supposed to be:
  • Talk time: Up to 8 hours
  • Standby time: Up to 250 hours
  • Internet use: Up to 6 hours
  • Video playback: Up to 7 hours
  • Audio playback: Up to 24 hours


  • Of course I get no where near this unless I pay close attention to the fine print on the apple site:

    Talk Time: Testing conducted by Apple in May and June 2007 using preproduction iPhone units and software. All talk time testing was done connected to a 1900MHz network. All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks was turned off. Battery life depends on the cellular network, location, signal strength, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary.

    Standby Time: Testing conducted by Apple in May and June 2007 using preproduction iPhone units and software. All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks was turned off. Battery life depends on the cellular network, location, signal strength, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary.

    Internet over Wi-Fi: Testing conducted by Apple in May and June 2007 using preproduction iPhone units and software. Internet over Wi-Fi testing conducted using a closed network and dedicated web and mail server, simulating browsing to 20 popular URLs and checking mail once an hour. All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks and Auto-Brightness were turned off; WPA2 encryption was enabled. Battery life depends on the cellular network, location, signal strength, Wi-Fi connectivity, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary. Internet over EDGE: Testing conducted by Apple in May and June 2007 using preproduction iPhone units and software. Internet over EDGE testing conducted over a 1900MHz EDGE, using a dedicated web and mail server, simulating browsing to 20 popular URLs and checking mail once an hour. All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks and Auto-Brightness were turned off. Battery life depends on the cellular network, location, signal strength, EDGE connectivity, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary.

    Video Playback: Testing conducted by Apple in May and June 2007 using preproduction iPhone units and software. Video content was a repeated 2 hour 23 minute movie purchased from the iTunes Store. All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks and Auto-Brightness were turned off. Battery life depends on the cellular network, location, signal strength, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary.

    Audio Playback: Testing conducted by Apple in May and June 2007 using preproduction iPhone units and software. The playlist consisted of 358 unique audio tracks, a combination of content imported from CDs using iTunes (128-Kbps AAC encoding) and content purchased from the iTunes Store (128-Kbps AAC encoding). All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks was turned off. Battery life depends on the cellular network, location, signal strength, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary.


    So... with all this in mind... Here's the real world experience battery Life:
  • Talk time: Up to 2.5 hours
  • Standby time: Up to 8 hours
  • Internet use: Up to 2.5 hours
  • Video playback: Up to 3 hours
  • Audio playback: Up to 6 hours


  • It's a guarantee that If you don't turn off your Wi-Fi radios the battery is gone in less than 5 hours no matter what you're doing. I can promise in the real world environment that you'll be recharging your iPhone twice a day no matter what. So just get used to it. I split it up like this... Overnight charge: Makes it fresh for all morning. End of work day charge: Lasts me for the next 3 hours to show my friends my cool phone.

    I wish I could change out the batter but then again... so does everyone else but don't worry we can all purchase this with our hard earned money with the next iPhone 2.0.

    My nifty handy dandy Corporate done (not drone) device seams to out perform your iPhone. Hmm, imagine that, Steve Jobs couldn’t mass produce a device designed in California to provide the same level of functionality that a mass produced device made in China designed by Research in Motion.

    In fact, my Blackberry 8800 has an outstanding battery life, with Bluetooth radio enabled at all times. I can go two to three days without needing a charge! SMS, MMS, no problem. Cut, copy, and paste a snap. E-mail? Yeah, I got that too. All through a carrier that understands my needs to send unlimited SMS messages, unlimited MMS, and unlimited data.

    yeah but your piece of junk is twice as thick, doesn't do video, certainly has no web browser like safari and doesn't do wifi.
    iPhone users sit tight. Nobody beats Apple for upgrades. Just wait and see. You don't think that Apple will constantly be upgrading the phone through your itunes software on a regular basis? You bet they will. Even as is the iphone kicks butt. It will only get better. Look at everything Apple does. The OSX, iTunes, ipod, etc. they always are improving the software!!!

    I understand why we have so many followers of the Apple faith; the products are so shinny with clean lines and sleek curves. Interestingly it is an Apple, which was used to deceive before, hmm any similarities? To be fair Apple made a good consumer device with the iPhone, but it will not replace corporate type devices such as the Blackberry. How many corporations use yahoo as their e-mail provider? I would venture to say small, very small businesses may, but really Exchange, Lotus, and even Groupwise are more prevalent in the business world. Perhaps that is not the demographic that Jobs is targeting anyway. Consumer seams to be the hotspot for the shinny sleek iPhone, nothing wrong with that. But really one can’t compare the iPhone, with a Blackberry, it’s just not the same tool. If I need to get work done, do it fast, and have e-mail push with tasks, contacts, calendar, and e-mail synchronized with my desktop via wireless technologies (EDGE/EVDO whatever) I pick up my Blackberry. If I need to try to impress someone with 70kbps connection with Safari then I pick up an iPhone (not really).
