Frequently asked
When will the POCO X8 Pro stop getting security updates?
POCO commits to six years of security patches from the March 2026 launch, so the X8 Pro should keep receiving fixes until roughly March 2032. Four of those years also bring full Android version upgrades, meaning the phone can climb from Android 16 to around Android 20 before it settles into security-only maintenance. That is one of the longest support windows offered on any phone near this price.
Is the POCO X8 Pro worth buying in 2026?
Yes, if performance-per-dollar and longevity matter more to you than cameras. The Dimensity 8500 Ultra is quick, the 6500mAh battery lasts well beyond a day, and the six-year patch guarantee means you can spread the roughly $349 cost across six years of safe use, working out to under $5 a month. The main compromise is the camera system, which is a single strong sensor rather than a flexible multi-lens setup.
Is the Redmi Note 15 5G an AMOLED phone?
Yes, it has a 6.77-inch AMOLED panel with 120Hz and up to 3200 nits peak brightness.
What is the battery and charging spec?
It packs a 5520mAh battery with 45W wired charging.
