I found an article detailing how a normal Droid RAZR's battery was swapped and fitted with a RAZR MAXX battery after some small modifications.

This led me to search the Internet for a replacement battery for the Droid 4, and I found the following.
Motorola Droid 4 XT894 Battery SNN5905A

Now, after reading these articles and seeing pictures of the battery being removed from the Droid 4, I feel very optimistic about an aftermarket company being able to develop a larger battery and back cover for the Droid 4. If all that needs to be done is peel the sticker off and remove a few small screws then that seems easy enough. I have noticed that when I take the back cover off my Droid 4 there seems to be a little extra space in between that may be able to accommodate let say a 2,500 mAh battery. I would like to see templates for at least two different sizes, a 2,500 mAh and a 3,300 mAh battery that could rival the RAZR Maxx. Now, I know we are still early in the life of the Droid 4 and I don't have any intentions of trading my Droid 4 in for a RAZR Maxx but I still wouldn't mind having a little extra juice for my Droid 4. What do you guys think and would you like to see a larger capacity battery/back cover developed for our Motorola Droid 4?

Ehh I would only consider doing a mod like this after a year since peeling the sticker voids the warranty..

For me, the question that keeps coming back is, 'WHY?!!'

What could be the reason that vzw demanded Moto put us through all these absurd gyrations?

It's not, as it's always supposed to be, about the money. The plastic bag hybrid battery costs more.

It appears that some vzw genius thinks that the best way to compete with Apple in this maverick Android market is to force us to buy Android phones that are more and more like iPhones.

Brilliant!

There are still folks out there that think Android style. Mozilla is about to out-Android Google:

What I want to know is where you get this idea that VZW is behind the non-removeable battery? Moto designs the phone, then shops it to carriers, either they bite or they dont.

Nah. No manufacturer makes anything without an eye to the market. Many, if not most, produce to fill customer orders.

In this case, it is well-known, for example, that Moto makes global phones and that vzw then demands that the GSM capabilities be disabled -- like with the D4.

The 'RAZR' concept is all vzw, not Moto. The Lady in Red, like Lola, gets what she wants. And it was her addictive mania for cellular anorexia that demanded the expensive, inconvenient, potentially dangerous, and altogether unnecessary polymer hybrid battery-in-a-bag.

Thats a great story. Got any evidence to back it?

That os has nothing to it if that is really what Firefox os really looks like

Well, I was wondering if Motorola has a patent on this battery design that could prevent an after market company from making a compatible larger capacity battery for the Droid 4? Maybe we'll have to wait for when the mythical Droid 4 Maxx Global becomes available and their batteries and spare parts start to show up on Ebay:biggrin:. Now, I would like to make it very clear that I am satisfied with the D4, but I guess I have the itch to supe it up even more than just rooting it. Right now we are just waiting on fastboot for D4, ICS:blink:, after market replacement parts, and the possibility of a future software update to enable the GSM radio (going to Germany for 2 weeks this summer). All these seem obtainable and not so far fetched to me. Check out this additional information in the links below.

No Moto patent. It's the same battery tech used in iPhones.

What I'd really like to see is a std Lithium hard metal case extended battery that would fit the D4. So, it'll be a major brick in my pocket -- it'll be a much more useful brick!

Nope. Totally different concept. More along the lines of Chrome OS.

Don't be too quick to count Mozilla out. The Firefox browser beat out IE when MS had 90% of the market. Firefox, of course, is a browser and not an operating system.

Btw FF11 browser out March 13 does have Flash support.

3D printing to make back cover.

Getting a larger back cover shouldn't be so hard or expensive. With todays 3D printing services you can choose to make it out of metal or plastic and since its a small object it will be inexpensive. Drawing the template shouldn't be so hard either, since using the old cover for dimensions.

If VZW told Motorola to make phones with non removable batteries, then why do the international versions of the RAZR (including the various Chinese models) have the same setup?

RAZR is completely Motorola's thing. The only thing VZW has is the name Droid, and they are paying Mr. Lucas to use that.
