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.

Since updating to Android 14, I have had this issue twice now. I notice that my phone has way less battery than normal at the end of the day. When I check what has used all of the battery, I see that firefox has used over 10% with only like 3 minutes of screen on time. Reinstalling the app seems to fix it, but I don't want to keep reinstalling.

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.

Background battery drain issues

I have noticed that for the past several months Firefox for Android begins draining my battery after being installed for around 2 weeks. I'm using a Google Pixel 7 (128GB) running Android 14 (AP1A.240405.002) in the UK.

At first, I thought this was being caused by an add-on, so I reinstalled without add-ons and slowly started enabling them day by day until I caught the culprit (which if I recall correctly was Dark Reader). However, even after I disabled the Dark Reader add-on the problem persisted, and no matter how many times I uninstalled and reinstalled the app, the background battery drain issues would eventually come back after ~2 weeks of being installed.

At present I have only three add-ons enabled in the browser: ClearURLs, Decentraleyes, and uBlock Origin. I have used these add-ons in the browser for years without any issues.

It's now got the point where I am so fed up with this issue and the need to constantly reinstall that I will be using a different browser for the time being until this is fixed. I really want to use Firefox as I use it on all my other devices, but this is too much of an issue for me to ignore.

I've included screenshots of my phone's battery consumption whilst I'm asleep, and whilst I'm watching Youtube on my TV over lunch. Both of these are times I'm not using Firefox.

Any help on this issue would be greatly appreciated.

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.

Firefox Consuming High System Resources on Xiaomi Redmi 13C with HyperOS Android 14

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.

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!

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.

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.
