T-Mobile G2 vs. T-Mobile G1 – Review

by Jerry D on September 16, 2010

It’s been two years since T-Mobile bravely launched the G1, the first phone to run the Android OS. Built by HTC, the G1 paved the way for smarter Android handsets like the HTC Desire, the Motorola Droid X and now the T-Mobile G2. How far has technology advanced? Let’s compare the two…

The T-Mobile G2 is equipped with a 3G/HSDPA (7.2Mbps) chipset, along with 802.11b/g/n Wi-Fi and Bluetooth 2.1 with EDR. It also boasts 4G connectivity using T-Mobile’s HSPA+ network where available, boosting speeds to 14.4Mbps. T-Mobile’s original G1 came with 3G/HSDPA (7.2Mbps), 802.11b/g Wi-Fi and Bluetooth 2.0 with A2DP as standard. (1-0)

Size & Weight:

According to the tape measure, there’s not much of a difference between the two cellphones – the T-Mobile G2 is 119.0 x 61.0 x 15.0mm; while the G1 measured 117.7 x 55.7 x 17.1mm. Overall, the G1 is smaller, with a distinctive ‘chin’. The T-Mobile G2 is the heavier is the two handsets. It weighs 184g, whereas the G1 is 26g lighter and weighs 158g. (1-1)



The T-Mobile G2 is equipped with a 5.0 Megapixel camera (2592 x 1944 pixels) with autofocus, an LED flash and HD video recording at 720p. The G1 launched with a 3.1 Megapixel camera (with autofocus), no frills, no LED flash, no video recording. It’s no match for the T-Mobile G2. (2-1)

Here’s how the raw technology of the cameras compare*.

1.0MP – 1280 x 960 pixels
2.0MP – 1600 x 1200 pixels
3.1MP – 2048 x 1536 pixels (T-Mobile G1)
5.0MP – 2592 x 1944 pixels (T-Mobile G2)
8.0MP – 3264 x 2448 pixels
10.0MP – 3872 x 2592 pixels
12.0MP – 4290 x 2800 pixels
16.0MP – 4920 x 3264 pixels

These are typical resolutions. Actual resolutions may vary


The T-Mobile G2 incorporates a touch-sensitive LCD display, 3.7 inches in size and with a resolution of 480 x 800. Packing 384,000 pixels into this 3.7-inch screen results in a pixel density of 252.162 pixels per inch (PPI). Like the G1, the T-Mobile G2 also includes a QWERTY keyboard, which slides out from the chassis using a clever Z-hinge mechanism.

The 3.2-inch touch-sensitive LCD screen on the G1 was smaller. It also boasted a poorer screen resolution – 320 by 480 pixels. In comparison to the new G2, there are only 153,600 pixels onscreen, which gave the G1 a pixel density of 180.313 pixels per inch. (3-1)



As for the processors and UIs, inside the T-Mobile G2 there’s a Snapdragon MSM7230 (with an integrated Adreno 205 graphics co-processor), rated at 800MHz. It might not have the allure of a 1GHz CPU, but early tests indicate that the extra Adreno muscle gives it performance to rival the Samsung Galaxy S. The G1, meanwhile, used a 528MHz Qualcomm MSM7201A processor.

The T-Mobile G1 is based on the latest Android 2.2 (Froyo) software, which is vastly improved from the original Android build launched with the G1. The original OS didn’t have a virtual keyboard, multi-touch or any customisable widgets (they were added in v1.5). There was also no video recording capability, no MS Exchange support and rudimentary media playback. But it was a start… (5-1)

Downloadable apps


The T-Mobile G2 boasts 12GB of storage (4GB onboard plus an 8GB memory card) compared to the default 1GB capacity of the G1. The T-Mobile G2 also includes a microSD card slot to ramp up the memory to 36GB. The inclusion of a microSD expansion slot on the G1 could only bump the capacity up to 8GB. (6-1)

Battery life:

With a full charge, the T-Mobile G2 boasts 6.5 hours of talktime according to HTC, while the G1 is rated at 6.8 hours. Standby time is rated at 420 hours and 319 hours respectively. There’s not much in it. (6-1)


The HTC T-Mobile G2 wins! (Obviously)

t mobile g2 T Mobile G2 vs. T Mobile G1 – ReviewTwo years is a long time in smartphone development and the T-Mobile G2 brings some cutting-edge tech to bear in this fight (6-1). In Android 2.2, it has an OS that is so much more versatile and powerful than the original version, adding Wi-Fi hotspot features and Flash 10.1 for desktop-like web browsing. It also has the highest-spec camera, the most memory, the superior display and it’s a super-thin phone. The next question is this: can it compete against newer smartphones like the iPhone 4 and Motorola Droid 2?
