Supposed iPad mini battery images reveal 16.7 watt-hour rating, much less that the new iPad

Supposed iPad mini battery images reveal 16.7 watt-hour rating, much less that the new iPad Two images that are thought to be of the battery from an iPad mini have surfaced overnight and they not only look legitimate but the performance figures of the battery seem to stack up too when placed against the new iPad and iPad 2; the images were sent to MacRumors.

MacRumors has received a pair of photos showing what is claimed to be the battery from Apple's forthcoming "iPad mini". The photos show a battery carrying a model number of A1445 and an Apple part number of 616-0641. The battery runs at 3.72 volts, offering 16.7 Whr of energy on 4490 mAh of charge.

The 16.7 watt-hour capacity for the iPad mini battery unsurprisingly places the device between the iPhone 5 at 5.45 watt-hours and the third-generation full-size iPad at 42.5 watt-hours. Given that the iPad mini has been said to be based more on the iPad 2 and lack a Retina display, the iPad mini's battery may be more appropriately compared to the 25 watt-hour battery of the iPad 2.

The battery figures would, if correct certainly appear to confirm what we have already heard and that is the iPad mini will not have a retina display but indeed be more in line with the iPad 2. Obviously the 7.85-inch screen would need less power that the iPad 2’s 9.7-inch screen, so to offer the same battery life, a smaller battery could be used. This particular battery is still in the testing stage and is not ready for a public release as there are blank areas for numbers and logos waiting to be added.

Not much longer to wait for all to be revealed, the iPad mini should be shown off at a press event by Apple on October 23; if all the recent rumors are correct. As that day approaches, expect more and more leaks and images of this exciting new Apple device.

This battery pretty much solidifies the rumor that the mini won't have a retina display, the battery capacity is way too small to run retina.

I agree. But, I'm kind of happy about that. Another way to look at it: Imagine if all that battery capacity in the iPad 3 (and CPU/GPU advancement) was applied to an iPad 2 rez display. Not only would it absolutely scream (in performance) but would run an awfully long time between charges. Or, it could be even thinner and lighter or some combination.

I realize that many love retina displays, but I'm not sure I'd make that tradeoff given the choice. I guess the performance and battery life are already good enough for most people, so maybe that is not a concern. It certainly would be nice if the iPad were a bit lighter.

I'm hoping the new mini is much lighter and thinner than it would be if Retina, especially that it will probably be popular as a reader or with kids. (In other words, I think Retina is a bit overblown as a feature, and poor trade-offs are being made, though I guess some with sharper eyes than me strongly disagree.)

Retina Display will be one of next year's features, after Apple confirms the mini is a hit. No need to put a Retina display on an untested product.

Yea, I'm sure it is inevitable. I'm not necessarily against it either, other than the tradeoff that is being made. I guess once it becomes the standard, then there won't be a non-option to compare with.

i don't think this is real iPad Mini battery, for many lied stay in Macrumor, and they released lots of fake news.

Amidst all-retina stalwarts, Apple could have definitely gone for a larger battery and a retina-supported display. This would now look less impressive among other devices.

Who cares how impressive it looks (among others). The question is.... will it get the job done? For that, it needs to be as light as possible, with a long battery life (and somewhat inexpensive). Retina display is a nice luxury, but it comes at the expense of other aspects.

After getting an iPad 3 for me and an iPhone for a couple of years now I have no desire to purchase a non-retina device. Call me spoiled but retina just blow non-retina out of the water.
