Flip the Droid 2 over, and you’ll find the battery cover. Yes, that’s right, an actual battery cover—you can remove the Droid 2 battery and replace it with a new one, unlike some other cellphones. To remove the battery, slide down the battery cover, and then lift out the battery.
To replace the battery, simply put it back into place. Now you can turn on the Droid 2.
Near the battery, you’ll also find what stores half of the Droid 2’s memory: the MicroSD card, which is about the size of a fingernail, and much smaller than the normal SD memory cards used in cameras. This card may be small, but it can hold 8 GB worth of data.
The Droid 2 has memory in two places—in the phone itself, and on the MicroSD card. To see how much memory you’ve got left in both, tap the Menu key from the Home screen, and then tap “SD card & phone storage”. In the SD card section, you can see how much storage space remains on the SD card, and under “Internal phone storage”, you can see how much space is left on your phone’s built-in storage. The Droid 2 comes with 8 GB of built-in memory and 8 GB on the MicroSD card.
If you want, you can remove the card and replace it with a new one, even one with more capacity, up to 32 GB. To do so, from the Home screen press the Menu key, and then choose Settings. Scroll down to “SD card & phone storage” and tap “Unmount SD card”.
After you’ve done that, slide out the battery and then slide out the MicroSD card. To insert a new MicroSD card, slide it into the empty space, replace the battery, and turn on the Droid 2. It should automatically recognize the new card and storage.
