The 3.7V Li-Ion battery inside the Galaxy Tab lists a capacity of 14.8 Watt-hours or 4000 mAh.

Samsung claims that the battery provides enough juice to watch seven hours of movies.

That seven hours isn't quite enough to last you though your favorite movie trilogy, something that the iPad would handle with ease.

Weighing in at 81 grams, the Galaxy Tab's battery is about 55% the weight and 60% the capacity of the iPad's hulk of a battery.

As highlighted in the third picture, the Galaxy Tab's battery is approximately half the size of the iPad's battery.

The rear-facing camera connector is pried up from its socket on the motherboard with the edge of an opening tool.

Say goodbye to the rear-facing camera...

Removing the motherboard requires disconnecting several connectors:

• Headphone jack/microphone cable
• Volume control cable
• Touchscreen cable
• Control button LED cable
• Display data cable

The motherboard is secured the rear panel by seven Phillips screws.

Removing the motherboard requires lifting it away from the rear panel.

The front facing camera easily separates from the motherboard assembly.

Let's lift that ugly EMI shield so we can take a peek at the Galaxy Tab's circuitry.

Let's examine the lineup:

• SanDisk SDIN4C2-16G (MLC NAND Flash 16 GB)
• Maxim 8998 (Power Management IC)
• Samsung S5PC110A01 + Samsung KB100D100YM (1GHz Hummingbird Multimedia Applications Processor + 8 Gb of MLC Flex OneNAND, 1 Gb of OneDRAM, and 3 Gb of mobile DDR).
• Infineon PM9801 (X-GOLD 616 HSDPA/HSUPA/EDGE Modem Solution)
• Wolfson Microelectronics WM8994 (Audio Codec)
• Infineon PMB5703 (RF Transceiver)

Chip lineup continued:

• Broadcom BCM4329 (Bluetooth/FM/WLAN receiver)
• STMicroelectronics L3G4200D (Gyroscope)
• ATMEL MXT224 (touchscreen controller)
• Broadcom BCM4751 (GPS receiver)

Two loudspeakers near the dock connector provide on-board audio for the Galaxy Tab.

So what makes the Samsung Galaxy Tab a true iPad competitor? The answer lies in the processor.

The Galaxy Tab is powered by the Samsung S5PC110A01 Multimedia Applications Processor.

Much like the iPad's A4 processor, the 1 GHz Hummingbird processor is an ARM processor featuring package-on-package construction to improve the speed and efficiency of internal processes.

Samsung takes advantage of the Package-on-Package architecture by embedding 8Gb of MLC Flex OneNAND, 1 Gb of OneDRAM and 3Gb of Mobile DDR into the processor.

The iPad's A4 processor embeds two layers of RAM (Samsung K4X1G323PE) into the processor's three layers.

One Phillips screw secures the headphone jack/microphone assembly to the rear panel.

After lifting it off some adhesive, it can be removed from the Galaxy Tab.

Luckily, the headphone jack is completely separate from the motherboard, making replacement trivial if you happen to break it when you drop your Galaxy Tab with the headphones plugged in.

Apple had similar ideas on the iPad.
