Having your phone on 100 percent charge may sound like the safest option to have all-day power, but it may be harmful to your phone long-term. Lithium ion battery is mostly used in most android devices and it degrade with time. Keeping your phone tightly charged all the time means it remains in the high voltage state, causes battery chemicals to age rapidly.
Research shows that fully charging your phone can reduce its battery capacity 10-15% more quickly compared to stopping at around 80–90 percent. Over time, it results in the battery life being shorter and a requirement to replace the battery much earlier.
However, the practice of charging to 100 percent sometimes, before traveling or on a busy day will not do much harm. The repeated habit of charging your battery completely slows down the wearing of the parts.
Best Charging Range for Battery Health
Most smartphone manufacturers advise people to keep their batteries between 50-80 percent whenever possible. Leaving your phone on a low battery or having it fully charged can cause the battery to wear out faster.
Fortunately, built-in battery protection is embedded on modern Android phones in the market today. For example:
- Samsung provides option of stopping charge at 85 percent using “protect battery” feature.
- Google Pixel has Adaptive Charging feature that limits the charging to 80 percent overnight.
These applications will save your phone a lot of time in maximum voltage and will maintain battery health.
Temperature & Fast Charging Matter Too
Apart from charging habits, temperatures are also play a major role in battery health. Extreme heat or cold degrades batteries much faster. It is should be maintained at 32°F and 95°F (0°C to 35°C).
Similarly, fast charging generates more heat, it may slowly reduce the battery capacity over time. It is convenient but relying on fast charging daily might not be best for long-term battery health.
Smart Charging Tips for Longer Battery Life
Some of the easy ways to keep your battery healthy are as follows
- Charge between 50–80% when possible.
- Avoid using your phone in extreme temperatures.
- Use original or certified chargers to avoid harmful changes of voltage.
- Activate Battery Saver mode when running low.
- Reduce screen brightness, turn off Bluetooth, and location when not in use.
- Check for battery draining apps in phone settings and updates.
There is no problem to charge smartphone to 100 percent, but doing it every day will reduce battery life. With proper charge range maintenance, sense of extreme heat, and battery optimization functionality features, you will extend the battery health of your Android phone.
