Here are some of the highlights from the teardown:

  • Motorola supplies a rear panel removal tool to assist owners in getting into the back of the device (although why it needs a tool I'm not sure).

  • There's a large sticker covering the battery with identifying information for the phone, as well as several statements telling the user that the battery is not removable. This is a negative departure from earlier Droids where the battery was user-replaceable.
  • The battery is a lot larger and more troublesome to remove than last year's model. Two T5 Torx screws and gobs of adhesive hold the battery in place. The adhesive is so strong that you may accidentally bend the battery too much (and cause it to possibly ignite) if you try removing it with just your fingers.
  • The Droid 4's keyboard pressure sensors are attached to the back of the motherboard, so you'll have to replace the entire motherboard if a key fails on your keyboard.
  • According to iFixit, the keyboard seems to be the best Droid keyboard yet.
  • Chip rundown: - Samsung K3PE7E00M-XGC1 4 Gb LPDDR2. - Hynix H8BCS0QG0MMR memory MCP containing Hynix DRAM and STM flash - Qualcomm MDM6600 supporting HSPA+ speeds of up to 14.4 Mbps - Qualcomm PM8028 chip working in conjunction with the Qualcomm MDM6600 to provide wireless data connection to the phone - Motorola T6VP0XBG-0001 LCM 2.0 LTE baseband processor - ZE55431140KHD, which appears to be the RAM sitting atop the 1.2 GHz main processor - Infineon 5726 SLU A1 - Skyworks 77483 700MHz LTE PA module - Avago ACPM-7868 quad-band power amplifier - Texas Instruments WL 1285C WiLink 7.0 single-chip WLAN, GPS, Bluetooth and FM solution - ST Ericsson CPCAP 6556002 System on a Chip

  • The LCD is not fused to the glass display, which means users won't have to purchase the LCD if they break the glass. On the downside however, users will have to replace the touchscreen controller when replacing the front display glass.

Because of the sticker and glue on the battery, the keyboard being integrated onto the motherboard and the touchscreen controller being integrated into the glass, iFixit have given the Droid 4 a repairability score of 4 out of 10 - the lowest score given to a smartphone bearing the Droid name.
