    I they were going to put in a new larger one but it's just taking a Razr apart.

    Fascinating to watch but I wouldn't want to do it.

    As mentioned by me in another thread, there are a couple things this video doesn't address that could cause people to be a bit apprehensive and should cause them to pause before choosing to tackle this. First, the battery is adhered to the back plate with double-sided tape. Removing the back plate requires a good bit of patience and muscle, but not an aggressive pull - rather a steady firm pressure that maintains a consistent level of prying action to prevent ripping that double-sided tape, and also without cracking the hard plastic bezel (surrounding the Kevlar). The video shows that the cover once removed is very flexible, but the plastic bezel is still succeptible to cracking or stressing from being bent too far.

    Also, when using the spudger (case pry tool), you must be EXTRA CAREFUL not to jam it into the very delicate foam rubber grommet at the bottom that surrounds the noise-cancelling microphone. It's visible in the video as a small grey teardrop shaped thing with a hole in it at the bottom of the inside after the case cover has been removed. The fact that you need both a T5 and a T3 driver to remove the battery connections and the stabilizer bar at the top of the battery will make it less likely an ammateur will tackle this task since the drivers are somewhat hard to come by. They can be ordered online but you generally can't buy them at local hardware stores.

    Next, the clips that hold the back cover on are only meant to be closed and locked once during manufacture, meaning they weren't engineered to be removed and replaced multiple times. This may cause the clips to lose some of their holding strength the first time they're removed (and every time thereafter), so the back will not be as secure going forward. Also, the double-sided tape will pick up all sorts of junk including airborne dust, dirt and oils from your fingers, etc., making it less sticky going forward. Considering the design incorporates the battery and back cover into the frame so that the entire phone becomes ONE SOLID laminated device, any damage to any of the clips or adhesives will reduce it's strength making it more succeptible to flexing.

    Finally, things you must also consider are that once opened, you may be eliminating any water resistance since the "coating" is only mollecules thick on parts and gaps, so tearing off the back will break those seals along the phone's edge and may also disrupt the coatings on components inside simply during the flexing while removing the back and battery. You'll notice that when he removed the battery it was actually bent slightly in the middle from pulling the tab, so the battery is somewhat flexible as well since it consists of only several laminates of plastics, metals, and pastes.

    Bending the battery may actually cause it to fail and could be catastrophic failure if laminates are able to make electrical contact causing an internal short. :mad: Also, the battery is capable of dumping a very large amount of its stored power in a flash and can be a fire hazzard if the contacts are shorted. :mad: Not only do they risk starting a fire by heating up whatever they touch, but the battery itself can overheat again potentially being a risk of fire or explosion. :mad: Handling a Lithium Ion Polymer battery (especially one that is naked such as this one) should be done with considerable care. :blink:

    Have you ever taken a Razr apart?
    Looking at two different sources, I see NO double sided tape on either the flexible back cover, or the battery to the components below it. So, please give some verifiable information as to this use of two-sided tape.

    As for the plastic retainers. I have not taken apart a Razr, but plenty of other electronic components and vehicle dashboards that use the same type of retainer clips. Be careful, take your time and they will not break. They retain their secure holding very well, even after taken apart quite a few times. (Break one and you have other options, but best to not break one). In addition, considering the flexibility of the rear cover, if you use the tool and primarily bend the back cover off the more solid retainers on the plastic frame of the phone will help you to not break a retainer.

    As for the water proofing; I would agree. Removing the cover will disturb any type of water proofing added to the phone. (I wonder how the tech will fix this problem.)

    This phone is designed to have the battery replaced by certified technicians, but that does not mean you can't replace it yourself. I would guess by removing the back and the battery there could be some way for a factory tech to verify so that the warranty could be considered void.

    I'm looking forward to somebody installing this and reporting back on how easy or hard to was to do.

    I'm also wondering how good the 3500mah battery will be? Is it like the cheap Chinese batteries that only last for a few week's before they start loosing their charge? I wouldn't want to have to replace the battery again anytime soon.

    Interesting information, FoxKat and Regt.

    I wonder how many tries and outtakes the guy had :p

    To answer your questions, YES, I did take one apart and have photos to prove it (see link to my Google Plus account https://plus.google.com/photos/115772237325720669006/albums/5696139162996003057 ). In the video, it is difficult to see the adhesive because they actually cut the video and fade to white at 1:21, and by the time they fade back at 1:22, he's got his thumb inside and the adhesive is almost completely detached. He fiddles with the last few clips, then with a final pull the last of the adhesive lets go. I guarantee you it took A LOT MORE TIME to remove the adhesive than the few seconds from the first clip disconnect and that last pull. For me, it was nearly 10 minutes altogether just to get the back cover off and to be sure I didn't destroy anything including the tape, since I didn't have a replacement tape to use if I destroyed it.

    In my pics, the clear double-sided tape can be seen if you look closely at the battery. You can see a slight discoloration and lines outlining the tape decal following across the bottom of the battery, up both sides, then across the top. There is a small cutout (about 1 square inch) in the middle where the battery doesn't have tape and that can be seen in one closeup. The cutout area includes the battery's power rating in 1750mAh and 6.7Wh, and also some of the warning ICONS. In the first very closup picture you can just make out the foam grommet around the noise cancelling microphone. In that pic you can also see the left end of the vibration motor and one of the offset weights (there are 2 weights, one on each end of the motor). Sorry for the picture quality, but I was in a low light situation and was using my D2 for the pics. There are also 2 double-sided tape swatches that can be seen on the back cover along the bottom edge inside.

    As for the plastic clips, they are not retainers - per se', meaning they are not separate clips (usually spring Steel) affixed to the case that fit into slots, like car retainer clips are. Instead they are simply bumps molded into the plastic bezel and there are corresponding slots molded into the mating bezel on the phone. These plastic "clips" are not really designed for multiple insertions. I am not saying they won't hold once replaced (mine did), and yes - if you take your time dislodging them you will likely do little if any harm to them, however most people doing this for the first time won't know exactly how to spread the sides and dislodge the clips without bending, distorting or possibly breaking off one or more. Removal is more a "spreading out" of the case cover, rather than a lifting.

    I have seen my fair share of the clips being bent or broken to the point where they no longer hold, in some cases the slot where the clip was intended to seat has been ripped open so there's no longer a thin sliver of plastic to grab onto, and even completely broken bezels when the person pulled too hard and in the wrong direction. In fact, the manufacturer is sort of counting on people who try doing such easily identifiable and irreversible damage so they can void the warranty if it is ever returned for a problem, whether related to the removal of the back or not. Some of these tiny clips are more hinges rather than snap-seat clips, so if you pull on them, you risk breaking them or the seat they fit into.

    My guess is that sooner or later someone is going to come out with a kit that allows you to use the Razrmaxx battery and cover on the Razr... Just makes sense.

    +1 again. As I said before, then we'll be able to get the MAXX out of our RAZRs! ;)

    From what I've seen the Maxx looks like the original without the bump on the back. So any adaptation would, I think, have to include a new back.

    But if you're going to do that, maybe just consider a Power Gen Ultra Slim which you could Velcro to the back? Not as slick, but more versatile and your warranty is still intact.

    Great shots, I'm still enjoying look at them. But I just noticed the battery ones say 1750 mAh and Moto's site says it's a 1780 mAh battery. It looks like there's a sticker over it too, as though it's been changed. Any idea on why or what that means?

    Same thinking here. First up is how much is the Maxx battery going for? Then, how much for the cover? Lastly, where? Once we have that I think we're home free. This solution would go a long way towards making me feel less peeved about the short release time between both models. The only down side is I'll need to buy a new Otterbox but that's not horrible. Always felt the phone was a bit too thin given the battery issues so this would make it ideal for me. Nearly double the battery life? Sold. With Actions Pro and this battery I should never have battery issues again.

    Yeah, I see that now that you mentioned it. It's not all that uncommon for either the manufacturer or Verizon to make such a mistake. I have to believe the label on the battery is correct.

    Also the area you mentioned looks like a label over the power rating is actually the 1" square area of the battery where they have a cutout of the double-sided tape to allow for the thicker area in middle of the Kevlar since that's where the Motorola badge on the back is attached and the inside has a plastic backing to support the badge. You can see the square plastic backing in photos of the inside of the Kevlar.

    If they didn't cut out the adhesive there, the back of the Kevlar wouldn't be smooth and flat as it is.

    That seems like faulty advertising to me. And, if it's just a mistake, why not correct it on their website?

    It just seems wrong.

    Just bought a t mobile branded portable external battery, supposed to be 1700mAh, I'll go with that and not risk the structural integrity of my phone, especially when its not meant to come apart
