A teardown by iFixit reveals that Donald Trump’s flagship MAGA phone, the
T1 Mobile, is a near clone of the HTC U24 Pro—a phone released two years ago.
Both devices exhibited similar internal structures upon CT scans and teardown, being functionally identical.
"They ran the phones through a CT scanner, tore them down to parts, and even put them back together into a functional Frankenstein phone with the U24 Pro’s board inside the T1 Phone’s chassis," highlighting their similarity
and confirming that the two phones are functionally identical. While there are slight alterations, such as a repositioned flash, differing speaker grilles, and variations in the chipset—Micron supplied parts for Trump Mobile, while SK Hynix provided them for HTC—the core components remain consistent across both models.
As for the battery, the T1 features a slightly larger cell manufactured in the Philippines, supporting slower 30W charging compared to its predecessor.
The T1 was initially marketed as 'Made in the USA,' though that claim was later diluted to 'brought to life right here in the USA' amidst criticism.
The striking similarity has raised questions about design and manufacturing strategies, as
"everything we've seen suggests that the T1 was manufactured in the same factory."Sources:
