If you want to use less data in Free Fire, you might want to try the following ideas:
• You should play the game on Wi-Fi whenever you can because it uses a lot less data than mobile data. Free Fire will not sync data when it is running in the background if you disable background data. Downloads and updates can only happen over Wi-Fi connections.
• It's possible to lower the amount of data that the game downloads and shows by lowering settings like resolution, frame rate, and textures. Voice communication uses more bandwidth, so turning off voice chat when it's not being used can also help save data.
• You can find apps that use a lot of data and change how much you use them by checking your phone's settings or using network tracking apps. Some other tips are to turn off in-game ads.
• If these steps don't help and Free Fire is still using too much data, you might want to contact Garena support for more help. They might be able to fix the problem or give you more information on how to effectively manage your data use.
