Firefox for Android v122 high battery usage

allabouteve — Thu, 25 Jan 2024 18:23:25 GMT

Hi members,

After updating my Firefox to version 122.0 (latest at the time of writing this), I have noticed a significant battery drain on my Samsung Galaxy A24. I believe the battery drain is due to the background CPU usage by the app which is higher than other frequent apps that I use. I do not keep tabs open in browser nor extensively use the browser as compared to other apps.

Few details that might help developers

- Handset: Samsung Galaxy A24 4G
- OS: Android 14 OneUI 6.0
- Google Play System Update: 1 November 2023
- Addons: uBlock Origin, TWP-Translate Web Pages, Google Search Fixer

Share your thoughts or suggest a fix. Thanks

I am also noticing this. It has used 39% of my battery since last charge with 1hr 52min running in the background and only 11min of screen time... which is odd since I only use mobile browsers in private/incognito mode, and it should be auto-closing. For now, I'm going to try setting it to restricted battery mode as I don't need any mobile browsers running in the background anyway.

The annoying thing with background usage limit is the refresh of opened tabs eveytime you briefly exit the app

Re: Firefox for Android v122 high battery usage

allabouteve — Tue, 30 Jan 2024 16:01:09 GMT

:: Update ::

This seems to be a deeper issue. The battery restriction mode (background usage limit) did not help so I installed Brave browser to use it temporarily. I kept Firefox, force stopped, deleted cache and put it in deep sleep and have not used it at all. This should, theoratically, disable the app, but to my surprise it is still running in background and consuming CPU resources.

Now what's left is uninstalling the app and reinstalling it. If the issue persist, I will report this bug on bugzilla.

theagentsmith — Sat, 03 Feb 2024 12:11:37 GMT

I have noticed my phone got noticeably hotter and draining battery faster than the usual while watching YouTube videos on Firefox 122.

Hope it can be fixed soon

Re: Firefox for Android v122 high battery usage

Mizar — Sat, 03 Feb 2024 14:07:33 GMT

Do you have sync enabled?

If so, try to disable it.

Re: Firefox for Android v122 high battery usage

theagentsmith — Sat, 03 Feb 2024 18:42:38 GMT

I have signed out of sync, let's see

Re: Firefox for Android v122 high battery usage

Vibi — Thu, 08 Feb 2024 02:44:26 GMT

Will also be trying to disable sync. Setting it to restricted battery does not seem to have made any impact.

edit-
Disabling sync has not made a difference on my end. I'm wondering if Android is misreporting the usage and using Firefox as a catchall for some other apps or services. I'm going to try uninstalling for a day and seeing if the drain is the same.

Re: Firefox for Android v122 high battery usage

JorisCS — Fri, 09 Feb 2024 12:07:46 GMT

I am experiencing the same issue on my Pixel 7 Pro. I have 51 minutes of screen time, which 5 minutes of those were spent on Firefox and its way ahead of any other apps that I've used so far, with even more screen time

Re: Firefox for Android v122 high battery usage

Mizar — Sat, 10 Feb 2024 18:16:07 GMT

These battery spikes are also massive on my end.

Will uninstall and see what happens as well.

Re: Firefox for Android v122 high battery usage

michaelsmith — Sun, 11 Feb 2024 15:59:41 GMT

I also notice that when I am using the firefox browser on my mobile. So, in a few minutes my phone is very drain and heat. Suddenly, the battery is quickly start to down and after that mobile is switched off.

Re: Firefox for Android v122 high battery usage

Mizar — Mon, 12 Feb 2024 12:22:37 GMT

Well, the battery spikes are gone.

So much for the mobile experience.

Re: Firefox for Android v122 high battery usage

skast — Tue, 13 Feb 2024 05:47:50 GMT

Same here, my phone (Pixel 7) is on flight mode while sleeping and Firefox is the only app that is draining the battery.

Re: Firefox for Android v122 high battery usage

captain_flint — Wed, 14 Feb 2024 22:47:49 GMT

Same issue for me on a Pixel 7 Pro. I used it for 22 minutes and its reporting 42% battery drain. Any plans for a fix?

Re: Firefox for Android v122 high battery usage

rafaelf — Fri, 23 Feb 2024 10:15:04 GMT

I had the same problem and ended up uninstalling the app. Now I noticed in PlayStore that Firefox has been updated to version 123.0. Does that solve the issue?

Re: Firefox for Android v122 high battery usage

Mizar — Fri, 23 Feb 2024 10:40:23 GMT

Only one way of finding out...

Re: Firefox for Android v122 high battery usage

captain_flint — Fri, 23 Feb 2024 15:41:28 GMT

No it doesn't. If anything it's even worse - 12 mins of screentime on FF used 21% of battery!

Re: Firefox for Android v122 high battery usage

rva60481 — Fri, 23 Feb 2024 21:03:27 GMT

Same thing for me since FF 122.0 and 123.0 :

High battery drain, phone and tab overheat when I watch video on Youtube (with ublock) !

I have noticed same thing with my phone and my 2 tablets :

S24 Ultra - Galaxy Tab S9 and Galaxy Tab S8 Ultra !

And last thing : Youtube video "lags" (10 FPS max). I have to pause the video and then restart it to get a smooth image...

I'm sure it comes from the last 2 versions of Firefox... nothing with FF 121.0

Re: Firefox for Android v122 high battery usage

rva60481 — Fri, 23 Feb 2024 17:16:47 GMT

Not solved... I have to desinstall FF for now

Re: Firefox for Android v122 high battery usage

rva60481 — Fri, 23 Feb 2024 21:06:28 GMT

I installed Firefox 121.1.0 from Aptoide and no more battery drain with youtube...

Edit : I spoke too fast, battery drain starts again (2000mAh vs 800mAh usually on my S9), but no more lags !

Re: Firefox for Android v122 high battery usage

captain_flint — Fri, 23 Feb 2024 19:13:35 GMT

What about in general? Does it drain battery with just general browsing the same way F 122 and above does?

Re: Firefox for Android v122 high battery usage

rva60481 — Fri, 23 Feb 2024 21:07:00 GMT

I think so...

But I will continue my research, and I suspect Android 14 compatibility issues with FF 122 and 123.

I will follow the list of developments since version 122

Re: Firefox for Android v122 high battery usage

Votterbin — Fri, 23 Feb 2024 22:22:42 GMT

I was experiencing the same on my S22 Ultra, went all the way back to v115 and haven't had any issues. I'll wait a few months and see if it's improved at all by that point

Re: Firefox for Android v122 high battery usage

mlargo — Tue, 27 Feb 2024 13:47:16 GMT

reducing battery drain should be the priority for the mobile teams of firefox!

I understand this takes work to accomplish but please focus on this.

Re: Firefox for Android v122 high battery usage

MythEng — Wed, 28 Feb 2024 16:24:32 GMT

Same thing happening on my Pixel 6 Pro with version 123.0 and I haven't even opened Firefox this today...

I tried restricting it's battery usage on device but it's still using around 30% of my battery and I may end up having to uninstall it for the time being.

Re: Firefox for Android v122 high battery usage

Tank — Fri, 01 Mar 2024 07:21:16 GMT

I just uninstalled and switched to Chrome. I like Firefox better, but the battery drain just kept getting worse it seemed. 37 min battery used with screen on... 6 hours and 37 minutes used in the background. No Bueno. What is it doing when not in use? Egads...

Re: Firefox for Android v122 high battery usage

allabouteve — Sun, 03 Mar 2024 12:03:10 GMT

It seems like the problem is not limited to Samsung Galaxy phone but Google Pixels are also experiencing the same and I would like to share few more encounters.

I tried Brave and Vivaldi browser because the problem still persists. Both of these browsers are Chromium based and do not provide the Firefox experience, that we all love. I found that adblockers do not work well, even with 97% score on d3ward adblock test and some sites do break!

So I had to return to Firefox and I installed version 123.0 in hope that the issue has now been fixed - It did not!
In fact, today received a notification (screenshot attached) saying Firefox is using system resources extensively which is a surprise because I barely used Firefox all day!

I believe Firefox backgroud processes are upto something - you can check them under Developer Options > Running services or Show cached processes (top right). I have now put the app into Deep Sleep state which seems to fix temporarily but will drain battery when ever you use Firefox!

I request Dev Team to please look into this matter or explain what are those background processes doing..

Re: Firefox for Android v122 high battery usage

AurelionLily — Tue, 05 Mar 2024 07:36:22 GMT

experiencing the same on pixel7a, went from 85% battery before sleep to 65% in the morning, was curious what caused it and the phone's reporting that firefox was the cause for 55-85% of the drainage per hour for the whole 8 hours

Re: Firefox for Android v122 high battery usage

captain_flint — Tue, 05 Mar 2024 15:53:42 GMT

Does anyone know if anyone at Firefox is looking into this? Is there a bug report filed with them? I went on the play store and nobody seems to mention about the battery, which is odd as its all over reddit etc. Yesterday it took 46% of my battery with 13 minutes of use!

Re: Firefox for Android v122 high battery usage

sBRB4Q7 — Thu, 07 Mar 2024 12:29:50 GMT

I've also noticed an increase in battery use.

My phone use is very minimal, just browsing mostly static sites, no videostreaming. On my motorola phone (G71 5G) with Android 12 my battery use after a single workday is nigh on 20%! It used to be it used about 10% if I was being conservative or around 13-15% at a max.

Currently it's sitting at 82% from 100% charge after about 7 hours of use. It used to be at around 90,92 or 89-85% in the old versions. It also never used to say Firefox has used 20% battery at the end of a day!

I used to have to charge on the 3rd day of phone use, now I need to charge after 2 dsys because it has used 50% of charge in 2 days!

Mozilla, please fix! Community, please file a bug! TYVM!

Re: Firefox for Android v122 high battery usage

sBRB4Q7 — Thu, 07 Mar 2024 12:47:51 GMT

I forgot to add (Why can't one edit in this forum?) are Firefox for Android derivatives like Fennec or Mull by Divest OS from F-droid affected by this bug?

Could someone check? Thanks in advance!

Re: Firefox for Android v122 high battery usage

tsenovIvam — Sun, 10 Mar 2024 20:10:26 GMT

My Pixel 6 does the same thing.

I reinstalled Firefox multiple times. I tried without sync, no extensions. Battery settings to restricted. Everything I could think of.

I had to switch to Vivaldi for now.

Re: Firefox for Android v122 high battery usage

allabouteve — Mon, 25 Mar 2024 18:37:21 GMT

:: Update ::
The issue continue in WaterFox as well. I have tried using it without addons but the battery usage is still high. Clearing cache and data maybe helps a little but im not sure. Ignore the solution below.

:: Temporary Solution ::

After the recent minor update v123.1.0 the issue persists. There are some background process running that Firefox dev team should explain. What are they doing?

However, since browsers like Mull and Iceraven are not available on Play Store and I'm not a fan of side loading apps, I found WaterFox browser to be a great alternative to Firefox. It is based on Fenix and has addon support too. I've been using it with the same addons that I use in Firefox and It has been working perfectly without any battery drain.

Re: Firefox for Android v122 high battery usage

allabouteve — Sat, 16 Mar 2024 15:35:52 GMT

I have used vivaldi and it is better than others but even with ublock origin filters, it shows ads on youtube and on certain websites. Give WaterFox browser a try

Re: Firefox for Android v122 high battery usage

allabouteve — Sat, 16 Mar 2024 15:37:39 GMT

I'm currently using WaterFox which is based on Fenix. So far, i have not seen any abnormal battery usage. In fact, I have been using browser frequently now without the fear of unwanted battery drain.

Re: Firefox for Android v122 high battery usage

Anonymous — Fri, 22 Mar 2024 16:00:26 GMT

You can use Firefox without the battery drain issue if you clear data and cache and don't sign in. When you sign in, its done for. Even when force stopping after sign in, it may still start itself back up. (I don't remember testing sign out and probably should as the person above didn't state what happened there.) That equals a very high probability of it being related to sign in / syncing / connectivity stuff but could be a bug as a side effect of doing so.

WaterFox, from what one review states, it seems like the syncing has a problem with it. Its possible that is an explanation as to why the above person isn't seeing the drain. But, that would have to be confirmed. That might also mean that it will see the battery drain in time.

I could build from source and debug it but I have my reasons to not. Did it before years ago and the issue was fixed something like 3-5 years later so its not necessarily worth doing anyway.

Have fun solving it however you each solve it 🙂

Re: Firefox for Android v122 high battery usage

vpsj — Thu, 28 Mar 2024 06:33:49 GMT

Currently using Firefox v124.1.0 and I'm getting the same battery drain on S23Ultra. I had a OnePlus before that was literally 6 years older and that did not suffer from any battery drain on Firefox.

I suspect it's an Android 14 + Firefox issue (since my OnePlus was on Android 10).

Are there any workarounds? Anything at all? My primary browser on my computer is Firefox so having it on my phone is super convenient since I can just 'resume' from where I left off and/or check my browsing history. It sucks that I am losing a couple of hours of battery life each day even if I am using Firefox less than 10-15 mins on my phone

Re: Firefox for Android v122 high battery usage

hongsj — Sun, 31 Mar 2024 15:33:30 GMT

My S23U was doing same, onscreen seems normal but background 5% in 1~2min.

On the other hand, Motorola Think phone with Android 14 showing no symptoms less than 1% for a day, with sync on.

Re: Firefox for Android v122 high battery usage

Synertic — Wed, 03 Apr 2024 20:17:27 GMT

I'm experiencing the same on my S24+. It drains so much battery even if I don't use it at all. The issue still persists on v124.

Re: Firefox for Android v122 high battery usage

vpsj — Sun, 07 Apr 2024 14:57:27 GMT

Tried Fennec as well. It worked fine for a few days but now it's draining as well.

9% for just 1 min of browsing? That's horrible. Genuinely no idea what's wrong with Firefox

Re: Firefox for Android v122 high battery usage

daaaaaavis — Wed, 10 Apr 2024 07:10:36 GMT

Same for S23 with OneUI 6.1.

I've been an avid Firefox supporter for years, but now I've been forced to switch to Chromium based browser. I removed Firefox completely and gained 1-1.5hrs of SOT a day. Battery stats showed Firefox consuming ~22% of my battery, even with actual usage being ~1hr. Switching to Vivaldi shows 4% battery consumption with the same usage.

Re: Firefox for Android v122 high battery usage

Foxrunner — Wed, 10 Apr 2024 18:08:51 GMT

I have tested Firefox, Fennec and waterfox. Sync off, battery restricted, no addons: all have the same behavior.

Mull on the other hand seems to work fine, no battery drain, yet. I'd guess it has to do with some background server sync, since Mull is the only fork that has strong fingerprinting protection and works better without addons.

However, it shouldn't be like this. I don't want to switch to chromium! Mozilla must fix this.

Re: Firefox for Android v122 high battery usage

SiggiB — Tue, 16 Apr 2024 08:50:39 GMT

Just to confirm having the same issue. Firefox 124.2.0 on Android Android 14, Samsung Galaxy S23 Ultra, UI 6.1. Consumption is 0,6%/h doing nothing at all. That results in about 10% a day.

Re: Firefox for Android v122 high battery usage

SiggiB — Wed, 17 Apr 2024 05:06:48 GMT

Running Fennec now. Perfect so far. Currious to see if consumption changes.

Re: Firefox for Android v122 high battery usage

mojali — Sun, 21 Apr 2024 11:42:16 GMT

We kindly request your assistance in resolving the battery issue on Firefox. We would prefer not to use Chrome on Android.

Re: Firefox for Android v122 high battery usage

SiggiB — Mon, 22 Apr 2024 11:26:15 GMT

Fennec still with normal consumption (not using it -> 0,1% in 12h)

Re: Firefox for Android v122 high battery usage

mojali — Tue, 23 Apr 2024 00:42:23 GMT

[Update] Closing all tabs and only opening a few tabs resolves this issue. It is likely that a specific website is causing Firefox to run continuously in the background.

Re: Firefox for Android v122 high battery usage

bwwh — Wed, 24 Apr 2024 21:20:23 GMT

Maybe it's the Notification Permission. Recently no drain with no Notification permission or they fixed in the current Nightly version.

Wait about 10-12 days. After that period consumption raised on my device.

Re: Firefox for Android v122 high battery usage

Aleksandr — Wed, 01 May 2024 13:32:32 GMT

OK, I will check and let you know

How many open tabs did you have? Was Mozilla Sync active?

Re: Firefox for Android v122 high battery usage

SiggiB — Sun, 05 May 2024 18:02:28 GMT

sorry for late reply.

Usually 2-8 tabs with automated closure after one day. Mozilla Sync was on.

Currently I have Firefox Beta installed, version 126.0b9. Let's see if the behaviour is the same.

Re: Firefox for Android v122 high battery usage

Aleksandr — Mon, 06 May 2024 07:31:35 GMT

Hi. After 1 week.

All looks good. Firefox sync is on, auto tab closure is off. No installed add-ons.

Re: Firefox for Android v122 high battery usage

firefox_user — Thu, 09 May 2024 13:40:35 GMT

Is anybody at Mozilla listening at all? This horrendous Android battery drain issue is going to be the end of Firefox mobile unless it gets addressed immediately. I've been a user since the Netscape days but this is a deal breaker. Their indifference and non-responsiveness are unacceptable.

Re: Firefox for Android v122 high battery usage

I'm using version 126.0 for 3 days now and the battery consumption seems okay. Right now at 3.2% with 23 min on screen. S23, sync on, uBlock Origin. Still testing, but looks promising. Can anyone confirm?

Re: Firefox for Android v122 high battery usage

Re: Firefox for Android v122 high battery usage

captain_flint — Fri, 31 May 2024 14:44:48 GMT

I had to uninstall Firefox and switched to Vivaldi - even though I would prefer to avoid a Chromium browser. On a Pixel 7 FF was consuming over 50% of my battery for around 35 minutes of browsing. The background usage was also insane. I don't know what the app is doing in the background but it was using a lot of battery. I did not have sync turned on - just uBlock was the only extension. Firefox have completely ignored us as well on this issue - we are talking into the void here. So I had no choice but to switch over to Vivaldi which uses a tiny amount of battery in comparison.

Re: Firefox for Android v122 high battery usage

I was experiencing this issue after transferring my Android profile to a new phone (upgrading Pixel 5 to Pixel 8). I cleared all cache/storage and did a clean reinstall of Firefox which seemed to resolve the issue.

Re: Firefox for Android v122 high battery usage

captain_flint — Fri, 14 Jun 2024 16:28:29 GMT

Hate to tell you, but it resolves it only temporarily. Battery issues come back after around a week of usage in my experience. Firefox really needs to fix this.

Re: Firefox for Android v122 high battery usage

oasis006 — Fri, 14 Jun 2024 19:41:17 GMT

Firefox consumes more battery than Chromium browsers for the same period of use.

Re: Firefox for Android v122 high battery usage

Guillaume42 — Sat, 15 Jun 2024 15:21:44 GMT

For those who were anxious about switching to another mobile browser, I moved to Vivaldi as the battery issue wasn't addressed for many months and it's been very smooth. Syncs with desktop, performance is great, adblocker, and the chrome extension store. No more battery issue, no more Firefox ... 🥲

On my Sony Xperia 1 V also very high consumption in the background 😥 even if I am logged out (so as not to synchronize). Uninstalled and switched back to Chrome for now.

Hopefully this issue will be resolved in the future.

Re: Firefox for Android v122 high battery usage

So far normal consumption.

lilly — Fri, 06 Dec 2024 07:13:03 GMT

Hi there,

I’ve also noticed increased battery usage with Firefox 122.0 on my Android device. It seems like the app’s background processes are consuming more power than usual, even when I’m not actively using it. I’m using a different device (e.g., Pixel 7), but it sounds similar to what you're experiencing with the Galaxy A24.

A few things I’ve tried that might help:

Disable unnecessary add-ons: Some add-ons can cause additional CPU usage, even in the background. Try disabling them temporarily to see if there's any improvement.
Clear cache/data: Sometimes accumulated data can slow down the app. Try clearing Firefox’s cache and data in the app settings.
Check for background processes: Ensure that Firefox isn’t running processes in the background that you don’t need, like sync or media playback.
Update the app: Make sure you’re on the latest Firefox version, as updates often fix bugs like this.

If none of these steps help, I’d suggest reaching out to Mozilla’s support or submitting a bug report so they can investigate this issue further. Hope this helps, and let me know if you find any other solutions!
Best Regard:

Thanks for the suggestion, SiggiB! I appreciate the tip about updating to the latest version of Firefox. I’ll definitely check if version 134 addresses the battery usage issue. Sometimes, updates can fix bugs or improve performance, so it’s worth trying out. I'll let you know how it goes!

Same here, version 133, pixel 9 pro xl. I put plane mode at night with 35% battery remaining and I wake up with 2% battery. I love many of Firefox' features so I want to keep using it but I also want to be able to have battery for the day...

Is this still a common issue? Switched to FF on my pixel 7 pro a few weeks ago and it's got quite bad. Last I seen is some people being fixed in January and some still having issues
