What this sale actually covers
Xiaomi is running discounts across four devices: the POCO M8 (256GB at £209, 512GB higher), Redmi Note 15 4G at £129, Redmi Pad 2 4G 256GB at £135, and the entry-level Poco C85 from £94. These are Prime prices, so availability isn't guaranteed to last. The HotUKDeals heat score of 985 degrees suggests the community thinks at least some of these are legitimately good - not just nominally discounted.
Where the value actually sits
The Redmi Note 15 4G at £129 is the most interesting proposition here. For someone replacing a cracked older phone with no budget for a flagship, it does the basics competently. The POCO M8 at £209 with 512GB of storage is harder to argue against on pure specs-per-pound terms, particularly if you've ever filled up a 128GB phone halfway through a holiday.
The Redmi Pad 2 at £135 makes sense for a child's tablet or a bedside media device. As a productivity tool, less so.
The honest problems with budget Android
Here's the thing nobody puts in the press release: budget Android devices across the board suffer from short software support windows. Xiaomi has improved, but you're unlikely to see more than two or three years of OS updates. Security patches drop off too. That matters if you use mobile banking or store anything sensitive.
The cameras are also fine-for-the-price, which is a diplomatic way of saying they struggle in low light and video stabilisation is an afterthought.
If you're amortising a £129 phone over two years, that's about £5.40 a month. At that maths, the Redmi Note 15 is hard to dismiss for a secondary device or a first smartphone for a teenager. The POCO M8 takes a bit more justification - but 512GB storage at that price is genuinely difficult to match.
