Phone barely lasts a day, drops 20–40% on standby overnight, or shuts down at 30–40% remaining. Lithium-ion cells degrade after about 18–30 months of daily use.
- ── What we replace

- ── Common on
- iPhone after the second year, Samsung Galaxy after the third year.
- ── Notes
- We always check battery health first. Replacement is only worthwhile when the cell is genuinely worn.
