However it ought to make for a more rugged device. I suspect the day will quickly come when repairing stuff like this is impossible.
It seems like the only things I take apart any more are remote controls—when the buttons quit working you can clean the contact pads with rubbing alcohol and they're as good as new. Maybe if they were glued together a heat gun would work, but nowadays they're snapped—and I have no idea where the snaps are. I always wind up breaking a couple, so I have to tape the thing back together. Bring back screws—please!
A whole 0.2 wH? iFixit also states this might just be rounding up.
In any case, not really article worthy...Or worthy of me writing this. Touché
Or the news worthy thing may be that the famed secret Apple battery technology --- may be just a marketing hype. That you are getting amazing battery life because Apple put in a much better battery, but under-reporting their actual capacity.
The new battery holds 25 W-h?90,000 Joules?of energy. That's more than the old one (by a tiny bit). Who cares about amp-hours? The device will draw as much current as it needs. Drives me crazy on car batteries?so many "Amp-hours"?why are you telling me this? How much energy does it hold?
To keep it clear in your mind when trying to decipher what a batteries rating means try this.
Volts= how much work that the battery can provide at a given moment.

It?s there power management that they designed more efficiency, not the battery cell composition themselves.
There is no advanced battery chemistry --- they just under-reported the true capacity of the battery.
1) That is a page pertaining to notebooks, not the iPad.
2) It says the battery uses advanced battery chemistry; it does not state that they use any proprietary Apple chemistry.
3) Apple hasn't reported the capacity of the battery. The capacity is written on the battery itself, printed by the manufacturer of the battery (not Apple) and only visible to someone disassembling the product. It is not intended for the public to ever be aware of the battery's capacity.

Take out the AA batteries from your tv remote control, it will say something like 2000mah.
Since the beginning of time, batteries have been advertised based on mah.
ANYTIME a company uses a non-standard way to describe their products --- watch out. Apple is the only company to list their battery based on watts.
Consumers can't sue Apple because Apple is actually giving you MORE battery than they advertise. But the "secret" battery life technology --- nothing but marketing hype.

If only there was a way to determine mAh from Watts and Voltage. Hopefully one day we'll possess the math to figure it out.
Oh, and let's not forget that Apple is the company that lists realistic battery times for realistic usage and actually lists the audio, video, Internet for WiFi, internet for 3G, and talk time (for the iPhone). Show me a single other CE device that is that detailed or accurate.

The batteries in a device like the iPad are an order of magnitude larger. Comparing them to an AA battery in a remote is like comparing a lawnmower to a Humvee. Apple use a power rating that is perfectly understandable. I don't see why you have a gripe about this.
Why would anyone want to sue Apple for providing them with more battery capacity than they promised? Is this even the case?
You have again made the mistake of assuming that any battery technology Apple may be proud of is in the battery itself. Apple is proud of its power management. It doesn't make the batteries.
You seem to be determined to believe Apple is misleading people by hyping up some battery chemistry technology that doesn't exist. It has never made any such claims about its battery chemistry. Drop the cynicism; it's totally unfounded here.

Oh there is a way to do the math --- but Apple rounded off those watt figures so that you can't do the math accurately.
Nobody else lists battery life individually by tasks --- because no human being just use their device only for video, or only for audio or only for internet.
The emperor has no clothes. Apple just give you a bigger battery than they advertise --- which means that you as a consumer can't sue them (because you can only sue them for giving you something less than advertised).
I suspect Apple does this for competitive reasons. Apple isn't going to brag about how it manages to get the battery life it gets. That is one of Apple's competitive advantages. Further, consumers aren't meant to see the innards of the device.

Batteries of all kinds use mah ratings. Nobody else list their laptop batteries, or tablet batteries or feature phone batteries or smartphone batteries by watts.
The battery has a Apple parts number. Don't care who makes it --- it's an apple's part.
The so-called power management --- Apple give you a bigger battery than they advertise, gives you fast-task switching and no flash enabled browser.

He was being sarcastic. We know the maths is simple.
Your second paragraph has no point to it.
Why would anyone sue someone for giving them more than they advertised? Your mentality is baffling.

A million different kind of batteries from cell phones, to smartphones, to laptops, to tablets, to my AA batteries inside my tv remote control --- all are listed by mah ratings.

Dell list their batteries in the same way. Copied and pasted from Dell website '6-cell 48 WHr Li-Ion Battery' on the first laptop I clicked on. HP, Acer and Toshiba only state the number of cells in the battery, they don't even provide an empirical value of capacity.
For the love of all things holy, no mobile version of Adobe Flash currently ships. Ask Motorola.

There is nothing baffling. Apple found a LEGAL yet misleading way to advertise their supposed battery life advantage. Much like how Verizon found a LEGAL yet misleading way to advertise all their 3G territories --- that covers more cows than humans in the midwest.

You're being silly now. Apple has never claimed anything of the iPad's battery. It has only ever stated that the battery life of the product is remarkable, which is universally agreed.
Verizon cooked the statistics, Apple just states a fact. The iPad lasts 10 hours. It doesn't claim that you get some space-aged technology that makes its batteries better than everyone else's. It just states the iPad lasts 10 hours.
You'll find a lot just listing the number of "cells". It's simply amazing that Samab thinks Apple is so awful in having better than average batteries and isn't listing enough data despite listing more than the competition.

Glued together is never good from a repairability standpoint.
