GabyDoes overnight or any other prolonged charging damage a lithium-ion battery? And how can you take care of your phone to make it last as long as possible? The debate on this topic has been ongoing for years. It seems that experts have finally found answers to these questions.
Ritesh Chu, an associate professor at the School of Information and Communication Technology at CQUniversity Australia, explained that the lifespan of lithium-ion batteries depends on a number of factors. In particular, it is influenced by the year of manufacture and the chemical age. The latter refers to the gradual degradation of the battery due to variables such as temperature fluctuations, charging and discharging frequency, and the usage patterns of the phone. Over time, the chemical aging of lithium-ion batteries reduces their charge capacity, lifespan, and performance.
Research has shown that the battery smartphone A model released in 2019 can withstand an average of 850 full charge/discharge cycles before its capacity drops below 80 percent. This means that after two to three years of smartphone use, only 80% of the original battery capacity is retained. After that, it starts to discharge noticeably faster.
Whether can be to leave phone on charge all night ?
Most new generation smartphones take between 30 minutes to two hours to fully charge. The charging time depends on the battery capacity (larger ones require more time) as well as the power of the charger.
Charge the phone. throughout the night no only not needed – this is also accelerates battery aging. To extend the lifespan his services, it is advisable to avoid complete charging cycles (from 0 up to 100 percent ).
Charging the battery to 100 percent too often can shorten its lifespan. Therefore, the expert recommends charging the battery to 80 percent and not letting it drop below 20 percent.
By the way, many manufacturers have already implemented features to regulate this process. For example, the iPhone from Apple offers a charging delay function after reaching 80 percent. Meanwhile, Samsung Galaxy phones allow charging to be paused at 85 percent. Science Alert .
Can prolonged charging be dangerous for? smartphone ?
Theoretically, “overcharged” lithium-ion batteries can pose a risk of overheating and catching fire. The good news is that most modern phones have built-in protection. It automatically stops the process of “trickle charging” the battery beyond 100 percent, preventing any dangerous situations.
However, every time the battery level drops to 99 percent (due to background apps running), it starts to “softly” charge again.
Can a phone explode from excessive charge harvest ?
It is unlikely that a smartphone will explode as a result of charging, says Ritesh Chu. Moreover, most phones now have automatic protection against overcharging. However, in previous years, there have been reports in the information space about unexpected phone explosions. This usually occurred due to manufacturing defects, poor-quality equipment, or physical damage.
As the expert noted, lithium-ion batteries overheat when the heat generated during charging cannot dissipate. This can lead to burns or fires. Additionally, using a faulty or low-quality charger or cable can also cause overheating, fires, and damage to the smartphone.
How to prolong life battery ?
Here are a few ways to protect your phone’s battery.
- Install the latest software updates to keep your phone up to date.
- Use original or certified chargers, as the power of other chargers may not meet the required safety standards.
- Do not expose your phone to high temperatures: Apple and Samsung claim that their models work best at ambient temperatures between 0°C and 35°C.
- Limit the charge to 80% of the total capacity and do not allow it to drop below 20%.
- Do not charge your phone for an extended period, such as overnight; disconnect it from the power source once the battery reaches 100 percent.
- While charging, keep the smartphone in a well-ventilated area; do not place it or the charger under a blanket, pillow, or body when it is connected to a power source.
- Monitor the battery’s condition to timely detect unusual trends, such as prolonged charging delays or rapid discharging.
- If you notice that your phone is overheating excessively or the back panel is swollen, please contact a service center for inspection and repair.
