Longest Battery Life Smartphone: Moto X (Teardown)

Below are some snapshot from Ifixit teardown of Google/ Motorola new cell phone. One of the key features of Motorola cell phones have been their very long battery life. Is it due to the combination of Qualcomm processor and the power management chip, some of the other chips, or their custom system architecture (software/ hardware)?

The key chips in Moto X are listed below.

Insightful, timely, and accurate semiconductor consulting.

Motorola Moto X Teardown

Step 1 — Motorola Moto X Teardown 

  • The love child of Motorola and Google is here, and we are dying to crack open the little Motoroogle.
  • Technical Specifications:
    • Dual-core 1.7 GHz Qualcomm Snapdragon S4 Pro processor
    • 2 GB RAM
    • 4.7-inch 1280x720 pixels AMOLED display
    • 16 or 32 GB internal storage
    • Qualcomm Adreno 320 GPU
    • .........

      Step 9 

      • Motorola claims the Moto X battery can power through an amazing 24 hours of "mixed usage."
      • How does the Moto X accomplish such a feat with a 3.8 volt, 2200 mAh Lithium ion battery? The secret is in the X8 Mobile Computing System.
      • The Motorola X8 Mobile Computing System is comprised of a Qualcomm Snapdragon S4Pro family processor, a natural language processor and a contextual computing processor.
      • Motorola developed a custom system architecture, which, when coupled with eight processor cores, allows for the delegation of processing power:
        • 4 graphics processor cores for "stunning clarity"
        • 2 application processor cores for "swift action"
        • 2 low-power cores—"awaiting your next command"

      Step 10 

      • Out comes the upper midframe panel, housing the speaker, headphone jack, more antennas, and pressure contacts.
        • Yay, pressure contacts! We like spring pressure contacts because they don't require any work to disconnect.
      • This is possibly the most modular headphone jack we've ever seen. It pops right out of the upper midframe panel, spring contacts and all.

      Step 15 

      • Notable ICs on the motherboard:
        • Toshiba THGBMAG7A2JBAIR 16 GB eMMC NAND Flash
        • SK Hynix H9TKNNNBPDAR RAM (we assume that the Snapdragon S4 Pro is also layered under this IC)
        • Qualcomm PM8921 Power Management IC
        • Texas Instruments TMS320C55 Digital Signal Processor
        • NXP 44701 NFC Chip
        • Skyworks 77619-12 Multiband Multimode Power Amplifier Module for Quad-Band GSM / EDGE and Penta-Band (Bands I, II, IV, V, VIII) WCDMA/ HSDPA/ HSUPA/ HSPA+/ LTE
        • Texas Instruments MSP430 F5259 Mixed Signal Microcontroller

      Step 16 

      • Additional ICs:
        • Qualcomm WCD9310 Audio Codec
        • Qualcomm WCN3680 802.11ac Combo Wi-Fi/Bluetooth/FM
        • NXP TFA9890 High Efficiency Class-D Audio Amplifier
        • Skyworks 77737 SkyHi™ Power Amplifier Module for LTE Bands 12/17 (698-716 MHz)
        • EPCOS 7 959 Wireless LAN / Bluetooth Filters (IF)
        • 0V00660 A56G 1B
