Apple’s next-generation iPhone battery will increase in capacity slightly, but not as much as you might have expected. According to a recent photo leak published by 9to5mac, the iPhone 5 battery features a capacity of 1440 mAh and a new, increased voltage of 3.8.
This battery has only marginally higher capacity than the iPhone 4S’ 1430 mAh battery, and the 1420 mAh version of the iPhone 4. Also, the new battery—which is supposed to be part of the next-generation Smartphone—has a new voltage of 3.8, up from 3.7 (iPhone 4S and 4), and a slightly increased watts-per-hour measurement of 5.45 (5.3 iPhone 4S and 5.2 iPhone 4).
With this information in mind, we were wondering if the iPhone 5 will be an LTE-capable device, but we rapidly dismissed our doubts: LTE is a no-brainer, as the new iPad clearly shows where is Apple ringing the bell. With carriers around the globe set to upgrade their network to the much faster 4G network, and China Mobile already testing its Long-Term Evolution network, it is obvious that the iPhone 5 will feature 4G connectivity.
But as mobile users on 4G networks report, battery life is a “pain in the ass”, which means Apple’s 1440 mAh battery could cause a sharp drop in iPhone consumer satisfaction. The iPhone 4S’ battery life is already the No. 1 complaint of the iPhone user base. In addition to 4G LTE, the next-generation iPhone battery has to light up all 640 x 1136 pixels, so at first glance the 1440 mAh sounds like a bad decision. The battery ceases to become a problem if we consider two main change factors: Apple opted for the latest in-cell touch panel technology (or maybe IGZO panels?), and we expect the iPhone 5 to feature Qualcomm’s latest Gobi chips.
Why is this important? The key is power consumption. Apple has upgraded the battery by 15%, which sounds odd. But let’s take a look at what these new technologies mean in terms of power consumption. If Sharp will indeed be manufacturing the iPhone 5 display, then we expect the iPhone 5 to feature IGZO displays, technology famous for its energy- and cost-saving ability. An IGZO display means a 20% decrease in power consumption compared to the traditional LCD panel.
Going further, Qualcomm’s latest Gobi chips enable the iPhone 5 to connect to almost any network around the globe. In addition, the chipsets are implemented using a 28 nm manufacturing process, featuring significant improvements in performance and power consumption. To put it in numbers: the 28 nm process reduces both standby and operation power by more than 40%.
In other words, the iPhone 5 battery, which will hardly increase in capacity compared to the iPhone 4S’ 1430 mAh pack, will be able keep the next-generation iPhone up to Apple’s standards. Apple's current battery consumption stands at up to 8 hours on 3G, up to 14 hours on 2G, standby time up to 200 hours, Internet use 6 hours on 3G, 9 hours on Wi-Fi, video playback 10 hours and audio playback up to 40 hours. However, since this is a leak, it needs to be taken with a pinch of salt until Apple to confirms the iPhone battery specs in just 5 short weeks.Contact Us for News Tips, Corrections and Feedback
