In case anyone feels like taking their RAZR HD apart, here are some instructions:

1. Get the following items together first:
  • Little dish, to hold screws & parts so they're not lost
  • "T-5" torx screwdriver
  • Plastic or thick wooden toothpicks, for gently prying connectors apart
  • A box to hold the screen/pcb/etc. so they won't get damaged

2. Use the torx screwdriver to remove the two screws on the bottom.

3. This little plastic trim is going to fly out of the phone, so point it at your dish on the next step so it doesn't land under your couch.

4. Hold the phone like you'd hold a newspaper, and slide the screen up. (Like it was a slider phone). It should move about 1/4"

5. The screen will now unfold from the back. It's attached with 2 ribbon cables. You remove the cables by pulling on them

6. The screen is now detached. Put it in a box on a high shelf out of your way so it's not lost or stepped on.

7. There are 10 black screws to remove. Use your T-5 Torx screwdriver. Put all of them into your dish of safekeeping.

8. The metal camera clip (item 2) is now loose. Put it in your dish.
9. Remove the clear plastic over the speaker connector (item 1). It is held on with medium adhesive, you can use a thin blade to pry it away from the plastic. Put it in your dish.
10. Pry the button ribbon cable (item 3) off the PCB, it is held with a light adhesive. Then pull it out of the connector in the direction of the arrow (HINT: see maxx pictures)

12. The speaker cable plug is held in a "U" shaped channel. You detach it by pulling it towards you (away from the back of the phone). (HINT: see maxx pictures)
13. (optional) You can remove the camera by pulling the ribbon cable up. Not recommended- they are kind of annoying to re-attach.

13. Remove the plastic cover over the battery ribbon cable. It is held on with light adhesive.
14. Push/pull the battery cable down to detach it. (HINT: see maxx pictures) Remember to use plastic/wood to do this- when shorted, these batteries can literally melt metal instantly.

16. The battery is attached with double-sided tape. You have to pry it out by pulling on the sides. There are 2 "battery removal" stickers on the battery which suggest that is where you should pry. However, I found that I could most easily pull up the upper-left corner, which would let me put my fingers underneath to pull it off. Regardless of how you go about it, be gentle, as the battery is somewhat malleable (like clay) so you want to bend it as little as possible

Update:

Closer pictures of the back cover and chassis.
Also a picture of the EV30 battery electronics, for those considering attaching an induction charger. The arrows are:
Red: Where the battery leads are soldered. Clearly we can't attach charger there because it would bypass the safety electronics
Yellow: Snugly plugs into a socket on the PCB- no place to attach charging
Green: Where the plug is attached to electronics. Your best option.

Convert RAZR HD -> RAZR HD MAXX
Are you interested in frankensteining your RAZR HD to have the MAXX battery? YES, it can be done! You don't even have to remove the battery or speaker.

Once you have remove the PCBs from both phones, the back panels are an identical layout.

Yes the pictures + text are all mine. Have the higher-resolution pix but i downsized them all to 640x640 to fit on the forums.

Thanks for the compliments!

Great job - Grant2..Jut a small remark: I notice that the battery is 2460 mAh in your picture, and not 2530 mAh as the spec suggested.

I think our right, 70 mAh is is pretty small amount, could be a margin of error?

"2460/2530 mAh (min/typ)" ... i take that to mean:

2460 mAh = minimum (guaranteed by the manufacturing process and/or quality assurance testing)
2530 mAh = typical (most batteries will have this amount)

What's interesting is the "9.3/10Wh (min/typ)", which has double the tolerance (7%) as the mAh (2.8%)

2460 mAh @ 3.8v = 9.3Wh
2530 mAh @ 3.8v = 9.6Wh

So I suspect that the package, for whatever reason, overstates the "typical" Wh slightly.
