Should I buy Redmi 6 in 2026-2026?
Buying this smartphone today only makes sense as a device for specific tasks: a phone for a child, the first smartphone for an elderly person, a device for navigating in a car or a music player. Its performance is no longer enough for heavy modern applications and multitasking.
The aftermarket price is extremely low, making it affordable, but many apps are gradually phased out of support for older versions of Android, and if you need a phone for calling, WhatsApp, and YouTube (in low quality), it will do just fine.
When choosing, be sure to check the screen for burnt pixels and microphone performance. These components suffer primarily from time. Also make sure that the set comes with a working charger, as it is more difficult to find the original one now.
