The pace at which new iPhone a.k.a iPhone 5 leaks are being brought to the scene, it is quite likely that we’ll have a fully functional handset before Apple makes it official on September 12th event. The latest leak relates to the next generation iPhone’s slightly more powerful battery, as newly surfaced photos of alleged iPhone 5 battery packs indicate a capacity of 1440 mAh, as noted by 9to5Mac. The source also points out that a battery with capacity of 1430 mAh is installed on the iPhone 4S while one with 1420 mAh is hosted the iPhone 4. Similary, leaked photos of battery packs show a higher voltage of 3.8V.
Detailing from the source:
Along with the increase in battery capacity, the new battery also features a new voltage of 3.8. This is up slightly from 3.7 on both the iPhone 4S and iPhone 4. The new battery also has an increased watts-per-hour measurement (wHr), 5.45 wHr, which is an increase from 5.25 and 5.3 on the iPhone 4 and iPhone 4S, respectively. This is a proportional increase due to the increase from 1430 to 1440 mAh.
According to the battery’s labeling, it appears that it was produced in June, 2012. That’s right on schedule for next-generation iPhone component manufacturing.
Looks like the jump in battery capacity from the previous iPhones to this new one is not going to be that prominent after all.
