I noticed Signal showing on my battery most use list. I'm using GrapheneOS in a Pixel 5. Battery optimization is disabled since I'm not using Google Services for push notifications. Signal is version 5.44.3. previous two versions showed the same problem. |
|
Same issue on Pixel 6a with GrapheneOS without Google play services.
Pixel 6a |

Exactly the same issue with LineageOS 19.1 on OnePlus9T without google services. If my assumption is correct maybe we could poll in intervals which could probably lower the battery drain? I don't need to get every message instantly and I'd be happy to have a setting allowing me to check for new messages every 1-5 or so minutes. Side note: I'm pretty sure it's been happening as well on older versions of Android. I've been using signal this way without google services for at least 3 years and battery drain was always an issue. |
|
I had a Pixel 3 and for the past years I've never seen Signal in the top list of apps that used more battery. For me it's recent. +3 months I think. I don't want to install an old version to test it |
|
One thing I've noticed for sure is that if you lock your screen with Signal in foreground - then it's draining battery even faster. |

Hi folks, unfortunately there's not much we can analyze as Android doesn't surface this information to us to include in our debuglogs. We'd need an Android Bug Report which dumps A TON OF INFORMATION about your entire device. Which is why we don't like asking for them. If you are able to reproduce this on a test device and willing to send us a report, please do so via email to cody at signal dot org. If you're tech savvy, and want to investigate it using the tooling we would, then you can check out Battery Historian at https://developer.android.com/topic/performance/power/battery-historian to get more details on what exactly SIgnal is doing that's draining your battery. |
|
Once I get my hands on a free device to fiddle with I could probably debug it. But it won't happen for another month and I have barely any experience with Android development. Anything in particular what to look for? Any tips other than link above? |
|
I hope it's appropriate to drop some info here on what seems to be the same issue recently for myself. I can't say I've seen these warnings from signal over the last year, but seem to get them regularly for the last few days. Signal v5.48.2

I had to delete Signal on my phone, it killed my battery. Samsung A52s 5G |
|
Have the exact same issue here, Pixel 4 running GrapheneOS based on Android 13. Weirdly though I only started seeing the awful battery life after the Android 13 update so I'm not 100% sure it's entirely Signal's fault. Edit: looking again it looks like other android versions have the issue as well. |
|
I'm having this issue using calyxos on a pixel 4a, using websockets for push notitcations. Accounts for 15% battery drain over 10 hours, all the while I had not touched the phone. Same issue with my wife's pixel 4a running calyxos except she's using MicroG cloud messaging for notifications. Both on Android 12. Both signal 5.48.3 |
|
I'm also experiencing this battery draining issue with Molly-FOSS, a Signal fork without google play services and I think it uses websockets for notifications. My battery drain is at this level I have also posted an issue about it to the respective fork repo mollyim/mollyim-android#126 and apparently this issue is an upstream issue, so I'm also posting about it here The issue contains some more information and a debug log |
|
Same issue on a Pixel 6 with GrapheneOS without Google Play Services. Seems to be worse on mobile data than on WiFi. |
|
I don't care anymore as I'll be unsintalling signal once sms support is dropped. I'm not using multiple apps to communicate. Time for Element/Matrix |
|
How's it looking with 5.53.8? It used to be that Signal was consistently at the top of my list in battery usage, but now it sits all the way down at the bottom alongside my keyboard. I'd be interested in knowing if people are still struggling with this, or if the various improvements in the newer version have actually helped. |
|
Same issue with Pixel 7 Pro stock, so with Android 13. VIdeocalling is borderline impossible (20% in 10 mins, super hot phone) and generally Signal takes a lot of battery even for normal chatting |
I didn't see any difference, issue persists on newer versions. |
|
It has been a bit better for me. Signal is still topping the charts, but not with as outrageous numbers as before. My phones battery lasts at least for 1-2 days, so its at acceptable levels I'd say.
Can confirm. I made a group video call and my phone got extremely hot during it. I think other participants in the call also had to plug their phones into a charger because it was draining so much battery. Their devices had google play services installed though, so that's most likely an entirely different issue |
|
As of me I wouldn't call battery drain excessive, but definitly more than other messangers/apps. |
|
I've noticed on my Pixel 6a phone with GrapheneOS that if I launch Signal Messenger then back out of it or press home (leaving it in the "system tray" let's say) then the battery usage is quite high. If I however bring up the "system tray" and clear all apps from the "system tray" or background then the Signal battery usage goes way down and the Signal background service still seems to work fine (I get calls/messages). This is opposite to how I've seen it work when using the Tutanota client for example. If I clear the Tutanota client from the "system tray" then battery usage goes way up and if I leave it running in the "system tray" then battery usage is way down. After a fresh reboot for example without launching any apps then Tutanota would use lots of battery but Signal would use little battery. After launching both apps without clearing the "system tray" then Signal battery usage would go up but Tutanota's would go down. I would hope that there's a smart way for each app to find out if they're cached and then behave accordingly. Has anyone experienced this behavior? |
|
I am also experiencing severe battery drain with signal in the background. I'm using a Pixel 4a with stock Android 13. My battery went from 50% to dead overnight with signal being the biggest battery user in each two hour section of the battery usage graph shown below. I was also fast asleep during these hours, so I was not using the app.
|
|
I found the reason for my higher power consumption (compared to my previous installation). I use microG and this includes cloud messaging. Usually this can be used by apps, but it seems that Signal doesn't use it first. So it has to do this job on it's own. After delete and reinstall it recognises the microG service and returns to a moderate power drain. BTW: Power drain has been low in Flight mode. Please check that too. |
|
Same/similar issue here.
|
|
So after my comment yesterday, I changed Signals battery profile in Android 13 from Optimized to Restricted and charged the device to 100%. Waking up this morning, my overnight battery drain is waaaay better. I lost about 10% battery overnight vs the 50% lost when signal was set to Optimized. Signal is definitely putting in over time in the background when it shouldn't be. |

To those newly posting on this issue, are you using the background websocket without google push notifications or using push notifications? Additionally, if you are able to reproduce this issue on a test device, providing an Android Bug Report is the most helpful for looking at battery drain issues. I call out test device because an Android Bug Report contains a ton of personal information we'd rather you not send us and likely you'd rather not share. Here's the tool we like to use to look at battery usage, feel free to use it yourself and report back what you see: |
|
@cody-signal since I am using stock Android 13 (not rooted), I am assuming that I am just using google's push notifications as is. I'm going to look around for a test device that supports the latest version of Signal to see if I can gather more data. |
|
Hi, just to be sure on the push notification questions. If i go to App-Info on Signal and then notifications all are enabled. In case of other things for testing - let me know. Edit:
|
|
The easiest way would be to look at your debuglog and in the top block there will be a line like:
If it's false, you are in websocket mode, and if true, you are using Google's push notification system. Based on your device details I'm going to guess you are in push mode, but it's worth double checking. |
|
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions. |
|
The problem is still present, so the issue should stay open |
|
Signal should implement unifiedpush |
|
Yeah, issue is still there. I've just learnt to live with this fact and I just don't let signal run in background. Means I'm missing a lot of messages right away but I've just learnt to start up signal whenever I grab my phone. Better to do that than have really short battery life. |
|
Whatever downstream changes Molly messenger did, worked for me for this issue. Signal should merge these related changes. |
|
@Ronkn since which molly version you are seeing improvements? Are you using websockets for notifications or UP? |
|
I also installed Molly today (v7.8.1-1) to also test the power consumption behavior while being fully reachable again (no app power management restrictions). Let's see. |
I've been on it for a while now. 4 months or so. Yes I'm using websockets for notifications. Currently using the latest version available on fdroid. |
|
Molly with unified push moves the battery usage to ntfy (the app that triggers signal when there are notifications). The total battery usage of both apps is down to 10-15% of the battery per day from whatever it was signal had (it's been so long since moving to Molly).
Even without unified push, the mentioned fix (that still hasn't been merged by the signal team) had reduced battery usage to more normal levels even before going unified push.
|
|
The ideal solution is definitely for signal to enable unifiedpush |
|
@Ronkn @LoveIsGrief can you please share what is the size of User Data for Molly under App Info page? eg for me its more than 20GB(on Signal). I'm trying to understand if that may also have an effect on battery drain. |
@Ronkn molly or molly-foss? |
|
My molly only has 3.27GB usage.
|
|
@jayb-g If it matters, I have all of my conversations set to delete after 2 weeks. I did this on signal too though when I was on it. |
|
@Ronkn Ok, I think that's good enough for comparison |
|
This problem still persists and almost makes my phone hard to use with the high idle drains. A fix would be really appreciated. Edit: |
|
@kushagra-xo do you use google services? |
|
The only solution to use signal without battery drain, for now, is to use molly unifiedpush version with mollysocket. It brings down total battery usage of molly-up + ntfy up to 5% at max. As I figure it has been years since the issue and people can't wait forever for signal to fix this. |
no, i do not. |
you need to self host mollysocket, which i don't find feasible for me. |
Ah! with only mollyup + ntfy.sh I won't get any difference at all? |
@duven87 this is as good as it gets. For now. On signal you might get up to 50% or more battery usage as reported by users.
Fly.io used to have free quota, the answer already links to the repo mollysocket-fly, which guides on how to set it up. Even if not free, it might cost you well under $5 or you can try aws but I have no experience with it. |
After several days of testing I have realized that the consumption has not changed anything with LOS+bitgapps on Pixel 4a.
|
|
@aventura-ms Langis might not be up to date. Whereas molly is same as latest signal as of now, and fast enough with follow up updates. |
|
that the updates go a little slower in exchange for having a phone that will last many hours more battery, I prefer it.

What a parasite, not even with google apps yields the battery. |
