[Fixed] Why is My Phone Battery Yellow and How to Fix it?
If your phone has been working well but suddenly, upon unlocking it, you notice the battery icon in the upper right corner of the screen has turned yellow, you may start to wonder what has happened. Rest assured, there is nothing wrong with your phone.
1. Why is your phone battery yellow?
When the phone battery turns yellow, it means that the device has entered low power mode.
This mode aims to prolong battery life by temporarily decreasing background activities such as mail fetching and downloads until the battery is sufficiently charged. It's worth noting that the color of a mobile phone's battery typically changes based on the battery level.
Usually, the battery turns yellow when low power mode is manually enabled or when certain phones automatically activate power saving mode when the battery falls below 20%.
2. The color of the mobile phone battery display at each stage
The color of your phone battery changes depending on its charge level. Typically, when your mobile phone is fully charged, the battery icon appears green (or white). The color green signifies safety and normality, and it indicates that the battery life is at 80% or above.
When the battery level is between 80% and 20%, and you enable power saving mode, the battery icon turns yellow. On the other hand, if the power saving mode is disabled, the battery icon remains green from 100% to 20%, and only turns red when the battery falls below 20% or 10%, depending on your phone brand.
If the battery life drops below 10%, the battery icon generally turns red, indicating a severe shortage of battery and the possibility of power failure.
3. How to switch it back to the normal color (green or white)?
Generally, you just need to turn off the power saving mode to change the battery from yellow to green or white. To turn Low Power Mode off, go to Settings, Battery. Besides, you can also turn Low Power Mode off from Control Center: Settings > Control Center > Customize Controls, and select Low Power Mode to add it to Control Center, then you can simply toggle it off or on.
4. What to do if my phone battery is still yellow even if the low power mode is off?
In most cases, it's unlikely that your phone battery will remain yellow when low power mode is not activated. If you encounter this issue, try restarting your phone to see if it resolves the problem. If the battery icon still appears yellow, it's possible that the battery health value is low, indicating that the battery is either old or damaged and can no longer support your phone's normal performance.
To check the battery health, navigate to Settings > Battery. If you find that the battery health is compromised, it's advisable to consider replacing the battery with a new one.
5. How to maximize battery life and lifespan
In fact, your phone's battery starts to wear out the first time you use the phone. However, you can take some effective measures to delay this wear and prolong the lifespan of your mobile phone battery. And here are some good tips to maximize battery life and lifespan:
- Enable battery health management. Some certain phones such as iPhone have built-in battery health management, which helps you to optimize battery charging and optimize charge limit to adapt to your daily usage to preserve your battery lifespan over time. You can simply enable it on Settings.
- Avoid extreme ambient temperatures. In fact, extreme temperatures are the biggest challenge for lithium batteries, so it’s especially important to avoid exposing your phone battery to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity.
- Avoid using irregular charging accessories. Using uncertified and substandard chargers and cables may cause certain damage to the phone battery.
- Avoid using your phone while charging. Using your phone while charging may cause the phone to overheat very seriously, thereby damaging your battery health.
