What are the factors that affect the battery life of OnePlus 12?

The battery life of OnePlus 12 depends on several factors, such as the software, the hardware, the usage, and the environment. Here are some of the common factors that can affect the battery life of OnePlus 12:

  • Software updates. Sometimes, software updates can introduce bugs or glitches that can cause excessive battery drain. For example, some users reported that their OnePlus 12 devices started draining battery faster after updating to OxygenOS. This can be due to the system optimization, the app compatibility, or the background processes. Usually, OnePlus releases another update that fixes the battery drain issue, or you can try some solutions such as factory data reset or firmware downgrade.
  • Screen settings. The screen is one of the most power-hungry components of OnePlus 12, as it has a large size, a high resolution, and a high refresh rate. The screen brightness and the refresh rate can affect the battery consumption significantly. For example, using the maximum brightness or the 120Hz refresh rate can drain the battery faster than using the adaptive brightness or the auto refresh rate.
  • Apps and services. The apps and services that run on OnePlus 12 can also consume battery power, especially if they are running in the foreground or the background. Some apps and services may use more CPU, GPU, RAM, or network resources than others, which can generate more heat and drain more battery. For example, gaming, streaming, or video calling apps can use more battery than browsing, messaging, or reading apps.
  • Charging habits. The way you charge your OnePlus 12 can also affect the battery life and health. For example, using a non-standard or incompatible charger or cable can cause slow or inconsistent charging. Charging your device too frequently or too infrequently can also degrade the battery capacity over time. Moreover, charging your device while using it or exposing it to extreme temperatures can also cause overheating and battery damage.

How can I check the battery usage and health of OnePlus 12?

OnePlus 12 has some built-in features that can help you check the battery usage and health of your device. Here are some steps that you can follow:

  • To check the battery usage, go to Settings > Battery > Battery Usage. You will see a graph that shows the battery level and the screen on time over time. You will also see a list of apps and services that have used the battery since the last full charge. You can tap on each app or service to see more details, such as the foreground and background usage, the mobile data and wifi usage, and the battery optimization settings.
  • To check the battery health, go to Settings > About Phone > Status > Battery Status. You will see the current battery level, the battery temperature, and the battery health. The battery health indicates the percentage of the original battery capacity that your device can hold. For example, if your battery health is 80%, it means that your device can only hold 80% of the charge that it could when it was new. The battery health can decline over time due to various factors, such as the charging cycles, the charging habits, and the environmental conditions.

How can I extend the battery life of OnePlus 12?

There are some simple and effective ways to extend the battery life of OnePlus 12. Here are some tips that you can try:

  • Update your software and apps regularly. Updating your software and apps can fix the bugs or glitches that may cause excessive battery drain. You can check for software updates by going to Settings > System > System Updates. You can also update your apps by going to the Google Play Store or the OnePlus Store and tapping on the Update All button.
  • Adjust your screen settings. You can reduce the battery consumption of your screen by lowering the brightness and the refresh rate. You can also enable the adaptive brightness and the auto refresh rate features, which will adjust the screen settings according to the ambient light and the content. You can access these features by going to Settings > Display > Brightness and Settings > Display > Refresh Rate.
  • Optimize your apps and services. You can optimize your apps and services by closing the unnecessary ones, disabling the automatic startup, limiting the background data, and allowing the battery optimization. You can also use the device’s built-in optimization features, such as the Game Mode or the Smart Boost, to enhance the performance and reduce the heat. You can access these features by going to Settings > Apps & Notifications > App Info and Settings > Battery > Battery Optimization .
  • Use the battery saver mode. The battery saver mode is a feature that can extend the battery life by reducing the device’s performance, limiting the background activity, and turning off some features, such as the wifi, the bluetooth, the location, and the sync. You can enable the battery saver mode by going to Settings > Battery > Battery Saver. You can also set it to turn on automatically when the battery level reaches a certain percentage.
