Today's smartphone batteries are mostly made from lithium-ion technology, which is famous for its superior performance but is also quite sensitive to user habits. One of the most common questions is: When should I charge my battery to avoid damaging it?
About lithium-ion batteries
Before we get into the best charging times, we need to understand how lithium-ion batteries work. Lithium-ion batteries operate optimally between 20% and 80% of their capacity. Overcharging or letting the battery completely drain can lead to faster battery deterioration.
How much battery percentage should the phone have left before charging to avoid damaging the battery?
When should I charge my phone?
1. Avoid letting your battery run out completely: One of the most common mistakes is letting your battery run out completely before charging it. This can damage your battery over time. Ideally, you should charge it when it has about 20-30% remaining.
2. Don't keep your battery at 100%: Many people think that charging to 100% is the best way to ensure a full battery throughout the day. However, constantly charging to full can reduce battery performance and lifespan. Most experts recommend only charging to around 80-90% to best protect your battery.
3. Frequent short charges, instead of full charges: Instead of letting the battery run low and then charging it up, try frequent short charges. The constant supply of energy keeps the battery operating at its optimal level of 20% to 80%.
Some other charging habits to watch out for:
Avoid overnight charging: Overnight charging can lead to overcharging if there is no automatic shut-off feature. Although many smartphones now have automatic shut-off features, leaving the charger plugged in for long periods of time can generate heat, which can damage the battery.
Use genuine cables and chargers: Genuine accessories will ensure stable current, protecting battery life better than products of unknown origin.
Charge at the right temperature: Temperatures that are too high or too low are not good for the battery. You should charge the battery in a cool environment and avoid leaving the phone in direct sunlight or near a heat source.
Battery management application
Most smartphones today are equipped with smart battery management applications, helping users monitor and optimize charging times. Take advantage of these applications to remind and optimize your battery usage.
