Put a RAZR Maxx Battery in an Atrix HD
It’s no secret that there are many Motorola customers who envy the battery life of the Droid RAZR Maxx. Compared to the Droid RAZR and the Motorola Atrix HD, the Droid RAZR gets way better battery life. We brought you news about a method to put the RAZR Maxx battery in the Droid RAZR. Now there is a method to do it to the Atrix HD.
XDA Forum Member smogtdi has posted a thread that is a compilation of other threads that actually show you the process. So far there isn’t a method that has pictures for every step, but the ones that do exist do have pictures showing the end result.
Essentially, the mod is based around getting enough space in the Atrix HD to fit the RAZR Maxx battery. What most have done is cut into the back of the Atrix HD to make extra room. As with most hardware mods, this can cause irreparable damage to your Atrix HD as well as void your warranty, so be extra cautious while doing it. However, once installed, users have reported getting up to double the battery life they were getting with the stock Atrix HD battery. Of course, any additional methods to get it done are welcome in the thread.
