The lifespan of a phone battery depends on various factors like manufacturing age, its chemical age, and usage patterns. Here's how you can extend it and what to avoid for maintaining its health.
Battery Lifespan Factors
Different factors can impact a phone battery's lifespan. The first is ‘manufacturing age', which refers to the period since the battery was produced. The ‘chemical age' of the battery, which is a measure of how much the battery chemicals have degraded, can also impact the lifespan. Lastly, usage patterns, such as how often and how much you use the phone, play a role as well.
The Effect of Chemical Ageing
Chemical ageing is one of the factors that can reduce a battery's lifespan. It can cause a decrease in charge capacity and overall performance. For instance, iPhone batteries are designed to retain up to 80% of their original capacity for 500 complete charge cycles. However, by 2019, smartphone batteries have improved enough to undergo 850 cycles before dropping below 80% capacity.
Charging Patterns and Their Impact
Time to charge a phone battery varies greatly, it depends on both the battery capacity and the power of the charger used. However, if you frequently charge your battery to 100%, it may affect the lifespan negatively. Additionally, keeping iPhones at full charge for extended periods might compromise the battery health. Although lithium-ion batteries can theoretically be overcharged leading to overheating and fire risks, most modern phones come with protections that stop charging when the battery reaches 100%.
When a battery drops to 99%, it enters a state of ‘trickle charge', which can wear it down over time. To counteract this, many manufacturers include features to regulate trickle charging. Thanks to these automatic protections, it's very unlikely that phones will explode from charging.
The Risk of Overheating
Overheating during charging can occur if the heat generated can't dissipate. Incorrect, faulty, or poor-quality chargers can contribute to this issue and may lead to both overheating and damage.
Recommended Battery Care
- Regular software updates
- Use only original chargers
- Avoid high temperatures
- Do not charge beyond 80% or let it fall below 20%
- Avoid leaving your phone charging for extended periods
- Disconnect the charger once it reaches 100%
- Keep your phone in a well-ventilated area while charging
- Monitor the battery health regularly
- If your phone heats up excessively or swells, get it checked at the service centre
Remember, for specific information on your phone and battery, it's best to follow the manufacturer's guidelines.
