A simple Reliability analysis on the battery component would have let the engineers know of the expected life of the batteries with a certain confidence (usually around 95% confidence). This should have been followed by an accelerated life testing to determine the age. Seems like they didn't do this proper Reliability assessment properly or discovered it after he products were launched (through extended Reliability tests and/or warranty analysis) is that's pretty dumb. 

Not everyone uses the battery the same, the issue is not the battery reliability  at all ( except for the batch they replaced for the iPhone 6). At least try to read the actual issue.

One can make a fairly good predictive model on the analytical data to predict usage with a fair amount of certainty. Obviously, it isn't a 100% accurate model of the usage pattern, but from a pure reliability engineering standpoint, I'd accept a model that's even 80% accurate to aim for a reliability estimation of the usage. 

Their reliability Engineering team needs to be fired for this fiasco. Guess they relied on the vendors assessment of Reliability estimation (and ask any experienced Reliability engineer and he will never accept a MTBF/MTTF number from a vendor and will perform their own analysis and testing). I know this from my current job in medical devices where we are required to predict battery life for lifesaving medical devices that we design. 

Hey buddy, got 30 years of computer engineering behind me (graduated from Polytechnique) so stop trying to be clever.
Everything you say is irrelevant. This has NOTHING TO DO WITH RELIABILITY. Actually read about the issue or stop posting about it.
You are the epitome of the low information commenter.

BTW, a medical device's range of use is way way way way more constricted than a consumer device in the hands of hundreds of millions (that goes without saying).
You can have people playing AA games all day long while others only use their phone to call and text.
This device which also has the power of a laptop with a battery 1/5 the size..
The peak usage of the latest A SOC's demand a lot more from the battery than in any other device that size.
Top of the line Androids have barely caught up single core performance of the A9 (the one in the 6s).

Not to mention that things like device size are key selling point that consumer actually want runs counter to provide a big battery.
Its not just Apple that wants a smaller battery, it's the consumer too. That the consumer doesn't quite understand the implication of this is pretty clear.

Also, even if only 5% of buyers are very heavy users who charges their device fully twice a day (0-10% to 100%), a lithium battery will be close to worn after 12 months (depending on ambient temp of use).

Those lets say 5% of users   (could be a higher or lower percentage), probably the most techies of users, are in the millions and they're likely some of the most active online. The result is predictable. Their voice will be heard all over social media. The fact is that other than changing the battery, Apple can't do much for these users other than keeping their phones from not functioning at all, which they did. I sure  The fact that they're heavy phone users means they've probably had early battery replacements in the past (cause otherwise their other phone would also be dead).

Should Apple actually spec their battery so those heavy users can use their phones for 2 years? Or will they more reasonably make sure 90% of their users can reach 2 years without changing batteries.

I said from day one when this first errupted this would be a huge PR problem for Apple. I wasn’t wrong. This is a good step though I agree with Ben Bajarin the $29 battery price should be permanent. Also I’m seeing quite a few posts from people saying their phone was fine with iOS 10 but when they upgraded to iOS 11 it really started to slow down. Seems there’s more issues than just the battery. Hopefully future point releases will fix these issues.

That huge PR problem exists in your wild imagination. No serious engineer talks without getting the results of the tests, benchmarks and other analysis. And Apple is managed by a serious engineer.

Ha, if it only exists in my imagination why did Apple release a statement? Why did they reduce the price of a battery replacement by $50? Why are they adding new features to iOS to give customers more visibility to the health of their battery? This was a huge PR issue that has affected Apple’s reputation and people’s trust in the company. You have have your head in the sand if you think otherwise.

Because it’s easier to spend money to change the narrative than trying to fix rampant misinformation and recall the distorted narrative that’s already out there. 

Easier , to accept you did not communicate properly and that some people may feel hurt by this error, and fix the perception issue to what amount as buying the peace. Letting the narrative, no matter how false it is, escalate further, may have damaged the brand which is far more costly.

Every new iOS version has this slowing effect in the first versions, want me to dig out the posts on iOS 4 5 7  8 9 10
good grief, there is a reason why mass hysteria and the placebo effect exist, people have terrible memories and also good at seeing things were none exist: aka conspiracies

I would think one of the main issues with a product like this is that it would just waste quite a bit of energy. It seems like it sends the EM radiation in a omnidirectional manner as a typical light bulb does. Only the EM flux that passes through the cross section of the collector (which I assume is a coil) provides useful power. The rest will just scatter and be absorbed by the surroundings.

It looks like their charging scheme is a lot better (more efficient) than a "space heater" radiator.

Their product page (http://http//www.energous.com/technology/receivers/) says this:

"WattUp® uses pocket-forming technology to accurately direct energy to the receiver. The technology dynamically adjusts the shape and content of the RF waves so they can be directed to a specific location in 3D space. (my emphasis) There, the energy is gathered by the receiver’s special antennas where WattUp® ASICs convert the RF signal to DC current, delivering a charge to the battery."

To me, this implies some sort of steerable (transmit) antenna, although "pocket-forming" means nothing to me. Their software technology page touts a highly configurable system of charging multiple devices at different power levels (and 3D locations), so there must be some micro-location method (beacons?) to tell the transmitter the device's exact 3D location. Of course, I could be reading too much into this.

I couldn't find what happens if you move the device during charging. Will it stop charging? Will the system redirect the charging signal dynamically as the device is moved?

You can form "pockets" in your field by simple interference pattern I guess if you have more than one transmitter, the more you have, the more you can tune your field, diminishing power in one transmitter, boosting another, beam forming, etc. This would require for sure that transmitter to know the position of the receiver.

The issue is Apple should’ve been for forthcoming on decisions like this. But it wouldn’t stop the conspiracy theories. 

We all know Apple is doing this to make people upgrade to either an iPhone 8 or iPhone X. /s

I bet there will soon be a lawsuit over this with some dipshit and some scumbag lawyer claiming this is what Apple is doing with no real proof what so ever. 

Apple is damned if they do and damned if they don't. 

They could at least let us know what they are doing. It's no secret for years that IOS updates slow down older device! There are plenty of Apple Fan boy who didn't want to here that, until now they get it from Apple LOL

That’s still not the case buddy, the phone would be deader without this so I fact really “slow ».
now most along with you “fanboy” shit
