Firefox for Android Support Forum

I am experiencing an issue where the Firefox browser on my Xiaomi Redmi 13C device running the HyperOS Android 14 operating system is consuming a very high amount of system resources, particularly CPU and RAM. This is causing my device to heat up significantly and draining the battery life at a faster rate.The specific problems I'm facing are: 1.Firefox requires special permissions and settings to function properly on my Xiaomi Redmi 13C device with HyperOS, such as exempting it from battery restrictions or granting it "autostart" permissions. Without these settings, the app crashes or doesn't work correctly. 2.However, when I grant these special permissions to Firefox, the app then starts consuming an excessive amount of CPU and RAM resources, much more than my other browsers like Chrome or Brave. 3.According to the system monitor, the Firefox processes are consuming the following resources: RAM 372M, CPU 39.0% Process "org.mozilla.firefox:tab12" RAM 742M , CPU 20.0% Process "org.mozilla.firefox" 4.This high resource consumption by Firefox leads to my Xiaomi Redmi 13C device overheating and the battery draining faster, negatively impacting the overall user experience. I have tried various troubleshooting steps, such as clearing the app's cache and data, using a lighter version of Firefox, and checking for updates, but the issue persists. I would appreciate if the Firefox support team could investigate this problem and provide any guidance or solutions to resolve the high system resource usage on my Xiaomi Redmi 13C device running the HyperOS Android 14 operating system.

Firefox is working in background and draining the battery. That what I see in battery usage information. I have tried to limit and stopped Firefox but it is still on the top of battery usage.

Hello everyone.

I'm noticing an abnormal battery usage in my Samsung Galaxy S24 Ultra. Ive used other Chromium based browsers without issues. Sadly I'll have to stop using it.

Dear team, 1) thanks for your work! 2) I can observe a quite important problem which could make me uninstall the app. Mozilla is now draining much power, even while not using it (e.g. at night where I can monitor the problem). I can observe that since I switched to a pixel 8 phone. (Which has itself a poor living battery). The phone can hardly survive a day and a night without being charged. And when charged on everything. It can loose up to 30% battery until the morning. Another phone could be 5%. What really strange is android show me that during that period of time Mozilla was responsible for 90% of this leakage. I had sync enabled.(Tabs, history and bookmarks) I removed it, but the leaked percentage of Mozilla at night stays around 70%.

Hello,

I'm facing a severe battery drain issue that occurs with all of the current Firefox versions for Android (Stable, Beta, Nightly). I have noticed that the problem mainly arises when I have played any type of video through the browser, such as a YouTube video or any auto-playing html video through a website. And I don't mean that the battery drain occurs WHILE I have the browser open, I mean in the background, after I have exited Firefox. I have also installed GSAM battery monitor with the necessary ADB battery stats permission given, and it seems that the "Video On" wakelock is always on with Firefox. It's like that the thread that plays the video has not stopped, even if I have force closed Firefox, and killed the video tab. For example, I'm attaching two screenshots from the battery monitor, where I have previously opened Firefox and played a video for like 15 seconds (see the "Audion On"), then immediately closed all the tabs and force closed the application. As you can see, the "Video On" has not stopped, like the "Audio On" wakelock, and continues to count (35 minutes). This may go on forever, such as if I leave the phone at night, I'll wake up the next day with Firefox video wakelock displaying something like 15 hours of playback (something that of course, is not true). The only way to stop the drain, is to restart the phone and not open Firefox.

Though, the issue may not even be related with video playback. I have read in the forums (like here: https://support.mozilla.org/en-US/questions/1432706) that other people are facing this issue as well, and worked around it by not using Firefox as the default browser. I have not tried it but, even if it works, this is not at all convenient. Other posts on reddit that verify the same issue I am having: https://www.reddit.com/r/pixel_phones/comments/18xh7w3/why_is_firefox_using_all_this_battery_i_havent/ https://www.reddit.com/r/zenfone/comments/18zlow0/since_android_14_video_seems_to_be_the_top/ https://www.reddit.com/r/firefox/comments/174d13d/firefox_excessive_battery_usage_on_android/

I do not wish to switch to chromium based browsers. Please take a look at the issue and let me know. Thanks a lot.

Firefox has been a great browser on my new S22 however I have noticed recently that it has been dropping my battery percentage extremely fast, and I notice its lower almost every minute I check. This is confirmed in the battery settings menu where it shows an abnormally high amount of usage, when I mainly use Firefox for general browsing and close background tabs.

I have a strong phone sd 870 and 6gb ram so need to put the blame on that.. but this browser keeps refreshing the webpage as soon as I leave to other apps.. yes I tried with no battery restrictions but didn't solve the problem

Hello,

Firefox 120 is freezing my Android 11 phone when I start typing on the search bar (weirdly it start to happens when a space is inserted). It freezes so hard that pretty much it takes 30-min to 1 hour for the phone to restart or the battery to drain.

Reverting to 119.1.1 solves the problem immediately.

My guess would be that maybe the search bar or the suggestion related code introduced something weird, as I do have a lot of bookmarks. Nevertheless, it's definitely a new issue (been using Firefox mobile since first day around 2010) and introduced in 120.0.

Since the phone is hard freezing, I can't even connect in ADB and try to see any message hinting at what's wrong. If there's a crash trace maybe some info could be dug there.

Thanks in advance for the help!
