Add Note Edit Step 1 — HTC Evo 4G Teardown  ¶ 

  • Today is a glorious day in the history of teardowns. We welcome the HTC Evo 4G to grandest stage of them all.

  • The Evo 4G's technical highlights include:

    • 1 GHz Qualcomm Snapdragon processor

    • 4.3 inch LCD Display

    • 512 MB RAM

    • Dual cameras (1.3 MP front and 8MP back)

    • HDMI output (requires adapter)

    • Android 2.1

Add Note Edit Step 2  ¶ 

  • The top of the Evo's smooth-contoured rear case is dominated by an 8 Megapixel camera and its two LED flashes.

  • A flip-out stand on its bottom edge allows the Evo to sit horizontally for watching videos on the 4.3" behemoth of a display.

Add Note Edit Step 3  ¶ 

  • After a bit of careful prying, the rear case easily pops off the Evo.

  • Holy red innards! Maybe it's because the Republic of China's flag is 3/4 red?

Add Note Edit Step 4  ¶ 

  • Like most reasonable phones, changing the Evo's battery is a snap.

  • The 3.7 V, 1500 mAh rechargeable Li-ion battery weighs in at 31 grams.

    • That's 23% more capacity than an iPhone 3GS, 15% more than a Droid Incredible, and 7% more than a Nexus One.

  • Look out! There's a liquid damage indicator on the battery's top edge.

Add Note Edit Step 5  ¶ 

  • We delve deeper into the Evo 4G by removing six T5 Torx screws and carefully prying off the internal frame with an iPod opening tool.

Add Note Edit Step 6  ¶ 

  • The internal frame is easily removed from the rest of the Evo.

  • It houses the stand, antennas, LED flashes, and speaker.

Add Note Edit Step 7  ¶ 

  • Two small Phillips screws secure the LED flash to the internal frame.

  • The dual LED flash assembly consists of no more than two LEDs soldered to a small interconnect board.

Add Note Edit Step 8  ¶ 

  • A small Phillips screw near the top left corner of the Evo is all that keeps the left side of the logic board snug in its cradle.

Add Note Edit Step 11  ¶ 

  • We used an iPod opening tool to separate the glass from the LCD and frame.

  • Removing the glass is not terribly difficult with the Evo 4G. This is great news for those unfortunate enough to drop their shiny phone and crack the glass.

Add Note Edit Step 12  ¶ 

  • Standing out on the board:

    • Several rows of pressure contacts connecting the antennas to the logic board.

    • The vibrator motor for...well...vibrating.

    • 8 Megapixel camera sensor.

    • Battery connector.

  • The other side of the board is about as featureless as it can be.
