I-Firefox ye-Android Community Forum

Hello, Long time user and lover. Never had any problems with your great browser. This past week, on my phone, Firefox has been flagged "high battery background usage" and is continuously trying to put app to deep sleep. What has happened? How do I stop this? Any help or suggestions would greatly be appreciated Thanks Scott

Android 14, One UI 6.0, Samsung S22+

Firefox is using a large amount of battery while idle. You can see my app runs open a lot of the day, but not in use much. It has drained 20 percent of one days battery, and I am watching YouTube videos on another app (Grayjay btw check it out!) and it has used far less battery. If I set Firefox into a sleeping state, the app still drains a lot of battery. When in deep sleep,it stops draining as much power, but then Android keeps auto pushing their own browser to be my primary browser. I'm not sure what to do in this case, as it's too much of a hassle to have links not auto open in Firefox when in deep sleep. This excessive battery drain doesn't make sense, and I was wondering if there was any fix for this. Thanks for taking the time.

Despite updating to the latest Firefox version (127.0) and performing a reset, I continue to face high CPU usage issues. The battery monitor reports extensive CPU consumption for minimal use, even when only a single tab is open. This problem is not exclusive to the main Firefox app; it persists across other Firefox-based browsers as well.

Device: Xiaomi (HyperOS - Android 14) Issue: High CPU usage across multiple Firefox versions Troubleshooting Done: App reset, tried alternative Firefox-based browsers

I urge the development team to investigate this recurring issue, as it significantly affects the performance and battery life of mobile devices. Your prompt attention to this matter would be greatly appreciated by all users experiencing similar problems.

I really like this app. I always use it on desktop also but after a few last updates I noticed that battery usage of this app increased a lot and the percentage is very high. 1 hour screen time on youtube was 4% battery usage but on the firefox side it was 17 min / 11% battery usage. If you fix this It will be perfect for me. Here are the screenshots with different days. And I'm using sync feature and ublock addon. I always close the opened apps and I use deep sleep feature on my samsung device. And I forced to close the app. For now I stop using firefox for test purposes.

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,

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.
