For everyone wondering if the original razr can accept the razr maxx battery, the answer is YES! Ive taken both of mine apart, and it would appear that the battery compartments are identical, but the one on the maxx is deeper ofcourse. So then I took the rear cover from the max and put it on the razr, it fit perfectly but there was a gap between the sim card door and cover, the gap isn’t that bad as you can see in the pictures. So, if you can find a maxx battery and rear cover, do the mod! And for all asking if it would be worth it. The answer is hell yes!!!!
