Photos of iPhone 5 Battery Leak to the Web, Reveal Incremental Bump in Capacity
The battery also sports a slightly higher voltage at 3.8V compared to 3.7V in both previous iPhone devices (4S and 4), along with an increased watts-per-hour (wHr) measurement. The new battery for the iPhone 5 is rated at 5.45 wHr, whereas the one in the iPhone 4S is rated at 5.25 wHr and the one in the iPhone 4 at 5.25 wHr.

It will be interesting to see how battery life plays out in real-world usage scenarios. If the rumors and speculation are true, the iPhone 5 will boast a bigger size touchscreen than any previous iPhone model, along with 4G LTE support. Both of these will drain battery life faster than ever before, though depending on what other tweaks and hardware end up in the iPhone 5, Apple could offset the increased power requirements in other ways.

With AC, volt-amps to watts varies by power factor and impedance, but with DC, VA=watts. 1440 mAh = 1.440 amp-hours times 3.8V equals 5.472 watt-hours, not 5.45, so one of those specs is off slightly. 4G seeking is going to kill battery life unless you spend most of your time in an area where ATT has rolled out their LTE system. They also need to come up with a way to differentiate the LTE Verizon, Sprint and ATT use, since I doubt they will be compatible for roaming as they operate on different frequencies (just like 2.4GHz and 5GHz radios won't talk to each other even if they are both running 802.11n). |

Im curious to see if the larger battery has better chemistry too, otherwise between the 4g and larger screen there might be some disappointing battery life in store for apple fans. |

Bigger battery or not still cant swap batteries. They would make extra revenue if they did that feature maybe on iphone 5? Choose me for the corsair contest. Love corsair love hothardware |

So bottom line... is that I'm going to have to recharge my phone at the end of every day if I get the iPhone 5? That's why I like my crappy little LG phone, keeps its charge for almost a week before I need to plug it in. |

Do you not already have to charge it every day? Share with me your secrets, wise one! |
