Most Xiaomi phones use Li-Polymer (Li-Po) or Li-Ion batteries.
Features:
high energy density

Under normal conditions:
1.5 – 3 years daily use
after ~500 cycles visible degradation begins

🔻 It downloads very quickly
🔻 It heats up excessively
🔻 The casing starts to swell
🔻 Slow or unstable charging
