Your iPhone sits on a desk at the end of a long day, and you unlock it to check a message.

Given this idea, you might want to know why is my iphone battery yellow. This guide explains what does a yellow battery mean on iphone, how to turn it off, and how innovative tools like Dr.Fone - System Repair can fix battery drain issues leading to Low Power Mode.

Part 1. What Does a Yellow Battery Mean on an iPhone?

The iphone battery yellow color means Low Power Mode is on, a feature that helps your phone save charge when the battery falls low. Hence, the icon turns yellow to indicate that power save mode is active, rather than the usual green or white. To clarify, this mode may turn on automatically when the battery drops below 20% after a prompt asks whether you want it.

Moreover, Low Power Mode disables additional tasks, such as mail fetch, app refreshes, and visual effects, to conserve energy. It may also reduce phone speed and dim the screen to extend battery life.

Besides, the phone may feel less smooth, and updates may show up late.

Part 3. 5 Tips to Prevent Yellow Battery Mode Frequently

To reduce how often the yellow battery icon appears on your iPhone, consider these 5 helpful tips:

tips for yellow battery icon

  1. Turn Off Screen Brightness & Auto-Lock: The screen uses the most battery, so keep brightness low in Control Center and avoid full brightness unless necessary. Moreover, adjust the auto-lock to a short time, say 30 seconds, to ensure that the phone goes off more often when it is not in use.
  2. Background Activity Control: Background apps can still consume power even when closed, so turn off Background App Refresh for unnecessary apps to save battery each day. Also, limit auto downloads, turn off alerts, and Lock Screen Live Activities so background tasks do not use up the battery.
  3. Control Connection Intelligently: Wi-Fi uses less energy than mobile information or 5G, so remain on Wi-Fi when there is a stable network, and it is ready to use at any place. Additionally, switch off Bluetooth, Personal Hotspot, or GPS-sensitive apps when you are not using them because every extra radio chip is using energy even when it is not in use.
  4. Optimize Charging & Battery Health: Turn on Optimized Battery Charging in Settings > Battery > Battery Health and Charging to help the phone conserve battery life and maintain peak health. Besides, one should never use non-trusted Apple chargers and cables, as this way the battery will get clean power and will not be ruined by cheap materials.
  5. Locate & Uninstall Battery-Hogging Apps: In Settings, go to Battery and then Battery Usage to find out which apps consume the most energy, and act right now when anything there looks excessive. Moreover, delete heavy apps, limit their usage, or switch to lighter alternatives, and update iOS regularly for better battery life.

Conclusion

To sum up, this detailed article has explained why the battery color on the iphone is yellow and whether it is safe to keep it for a long time. Moreover, some tips are provided to help avoid needing to access Low Power mode in the future. Still, if you experience frequent battery drain and use Low Power Mode, using Dr.Fone - System Repair is recommended, as the tool can fix 150+ iOS issues.
