Part of the Best 10 Singapore Glossary › Tech & Gadgets › Battery Cycle Count
A battery cycle is one complete discharge and recharge of your battery — from 100% down to 0% and back to 100%. Every lithium-ion battery has a finite number of cycles before its capacity significantly degrades.
Battery Cycles & Health
| Device | Typical Cycle Rating | Replace When |
|---|---|---|
| iPhone | ~500 cycles | Battery health below 80% |
| Android Phone | 300–500 cycles | Noticeably shorter battery life |
| Laptop | 300–500 cycles | Battery dies quickly or swells |
In Singapore’s heat, battery degradation happens faster than in cooler countries. Heat is the #1 enemy of lithium batteries — keeping your device in a cool environment and avoiding charging to 100% overnight extends battery life significantly.
