What "cycle life" means
| Term | Meaning |
| 1 cycle | One full charge (0% → 100%) |
| 2000 cycles | Battery still retains good capacity after 2000 full charges |
Partial charges count less – charging from 50% to 100% is ~0.5 cycles.
How long 2000 cycles last in real life
| Usage | Years until 2000 cycles |
| Charge every day | ~5.5 years |
| Charge every 2 days | ~11 years |
| Charge every 3 days | ~16 years |
Most users will replace the device before replacing the battery.
Capacity after 2000 cycles
| Cycle count | Expected remaining capacity |
| 0 cycles (new) | 100% |
| 500 cycles | ~90–95% |
| 1000 cycles | ~85–90% |
| 2000 cycles | ~80% |
80% after 2000 cycles is excellent – industry standard for quality batteries.
What affects battery life
| Good for battery | Bad for battery |
| Charge with 65W+ PD charger | Cheap non-PD chargers |
| Store at 50% if not using for months | Store at 0% or 100% for months |
| Keep cool (50–80°F / 10–27°C) | Extreme heat (car in summer) |
| Use regularly | Deep discharge (0%) for weeks |
Intelligent BMS protects against overcharge, over-discharge, and temperature.
Signs your battery is aging
| Symptom | What it means |
| Runtime feels shorter | Normal after years of use |
| Takes longer to charge | May be aging |
| Swelling or damage | Stop using – contact support |
Most users won't notice degradation until after 3–5 years.
