Anyone figured out how to check and extend storage health on a Redmi 9AT?
I’ve got a Redmi 9AT (2/32) that I want to keep as a backup phone, and I’ve heard budget phones with eMMC can slow down or die from write wear over time. I’m a beginner, so I’m looking for simple steps and apps if possible.
Questions:
- Is there a non-root way to see eMMC “lifetime”/health counters on the 9AT? Any app that actually works on MTK/MIUI for this phone?
- If root/ADB is needed, what’s the safest, minimal method just to read those counters? Example paths or commands welcome.
- Does MIUI on the 9AT run fstrim automatically? If not, can I trigger TRIM without root to keep things snappy?
- What settings reduce write load the most on MIUI 12.x for this device? Things like:
- Disabling system ads/analytics/“recommendations”
- Turning off auto-backups or chat/media auto-downloads
- Limiting background sync for certain apps
- Using lighter apps that cache less (suggestions?)
- Internal vs SD card: is it better for longevity to store media on an SD card? Is adoptable storage even possible/stable on the 9AT, and does it help or hurt eMMC wear?
- If the phone already feels sluggish, would a factory reset meaningfully help by re-trimming/rewriting data, or is that just a temporary band-aid?
- Any real-world reports: how long has your 9AT lasted with heavy messaging and photos? Early warning signs before the storage goes bad?
What I’ve tried:
- DevCheck/AIDA64 show basic storage info but not health.
- Switched off a few MIUI recommendations and reduced some auto-syncs, but not sure if it actually cuts writes.
Would love simple step-by-step tips, specific apps, or Termux commands that work on this exact model. My goal is to keep it usable for emergencies without unlocking the bootloader if possible.
