A54 5G Battery draining after few days

VincentKen — Thu, 13 Apr 2023 09:57:39 GMT

Hi all,

has anyone noticed battery draining after few days of usage? I leave my phone without WiFi overnight on Power Saving mode with 4G/3G/2G enabled. For the first few nights the phone uses minimal battery capacity (1-2 %), but after few days it uses over 15%. Usually restart helps.

Any ideas how to resolve this issue?

Thanks!

Hey @VincentKen

The A54 5G can last up to two days from a single charge! As for the battery usage, if there's any apps running in the background, this could cause the battery to drain. If you're unsure, or if you'd like to get a closer look at the battery usage, head into Settings > Battery and device care > Battery > Tap on the graph.

Thanks for the reply. I checked the graph and there is no background app, but still the battery goes down...

@VincentKen: To gain a better understanding of what might be causing your battery to drain, please charge it to 100% before you go to bed. The following morning, head to Settings > Battery and device care > Battery > Tap on the usage graph > Make sure that 'Since last full charge' is selected via the tabs at the top of the screen, then check the breakdown below the graph itself. Does anything stand out as using a higher than expected amount of battery?

In the meantime, please make sure to close any apps you're not using via the Recent button in your Navigation Bar (3 vertical lines). Also, head to Battery and device care, and select 'Optimise now' if prompted, followed by Memory > Clean now.

Hi @AndrewL ,

Thanks for the tips. I tried that as well as Cleaning the memory before sleeping. However, the battery still drains with no cause displayed (see the screenshot below):

Mine is the same. Charged to 100% before I went to bed, at 88% when I woke up. I've been to battery and the only thing running in the background is Google play services, but says that has only used 1%.
I'm at a loss!

After a bit of experimentation, I think I might have found a way to improve it. The following steps seem to improve the behavior:
1. Settings -> Security and privacy -> Find My Mobile -> Offline finding -> Switch off
2. Settings -> Lock screen -> Always On Display -> Switch off (despite having previously only Tap to show)
3. Restart the phone

It would be good if Samsung shows in the battery usage what percentage is used for the above features, so user can do an informed decision which to disable.

Hi All, thankyou so much for your message, unfortunately I've experiencing the same issue and I am really disappointed as was really looking forward to getting my phone. I've had the A54 for a couple if weeks whereby I was waiting to get a phone case before taking it out the house and using properly. However overnight my battery drained near to 20% I haven't been using the phone excessively at all. No videos and disappointingly not even tried the camera. I charged the phone today and already at 80% with very minimal use. I only am texting on WhatsApp that's it. I have posted the same query today. I have tried to do device maintenance but to no avail. Really upset as I've barely used the phone and explored what it can do 😪

Have you seen any improvements with the changes that you've made? I had about 15% battery drain overnight and I am thinking about returning the phone.

One additional detail I noticed - I have 5G disabled as my operator does not support it. If enabled, then it also drains battery overnight.

The Good Guardians Battery Tracker gives you more detailed info on battery usage...might be helpful.

Yesterday, I was able to finally see the pattern that triggers the battery draining. I used the phone in the same way as other days, however there was a short phone call in the morning. After it the battery just went down. Phone reboot fixed the problem as it is visible on the battery usage.

Is any Samsung person able to comment on this if a fix is coming? Rebooting phone after a phone call is just crazy! Thanks!

Interesting. I have not tested this myself, but will report back if I find the same behaviour.

Otherwise turning off Offline finding and 5G did help a lot with the battery drain. I only got 4% battery drain over ~9 hours overnight.

It seems this app is not available world wide. I can find links to it on the Samsung store if I google it, but once I click the links I get a message the the app has either been removed from the store or that it is not available in my country.

Where are you? It's available throughout USA and Europe. https://apps.samsung.com/appquery/appDetail.as?appId=com.android.samsung.utilityapp

I have noticed the same thing. Mine drains about 2-3%/hour. I'm gonna test it a bit more but if that's how it stays then back to Samsung it goes.

After yet another night of 15-20% battery decrease and no app reported as the battery drainer, I went over apps via "Apps" and noticed couple of Samsung apps with the same metrics:

Surely, Device Care app should not consume 10% over 8 hours when phone is not used.

I am having the same issue. 15% or more drain when phone is idle at night when I'm sleeping (with everything off) and then normal battery throughout the day

if i try the diagnostics tool the battery is normal,

But what I've noticed that it happens every two full charges. Let's say i fully charge my phone today and have the problem, if i charge it again the next day this doesn't happen. Usually restarting or turning off the phone for a couple of minutes solves the problem.

No unusual app found draining battery

I found something that might help figuring out why the battery is draining faster than expected. The first sceenshot below shows battery usage over time, together with CPU Utilization % and CPU average frequency.

Note that for the whole of Sunday, CPU utilization remained close to 100% and CPU frequency was almost constant until I restarted my phone (as indicated by the gap in the data). After this point CPU utilization varied normally and only increased when the phone was actually in use.

It's seems that the abnormally high CPU utilization caused the battery to be consumed much faster than expected. In the second screenshot this is clear as indicated by the steep slope for battery usage compared to the much flatter slope after the restart.

It is also worth noting that this high CPU utilization has been persisting for more than a day and throughout a charge before I noticed it, so it may be the case that a restart is necessary to fix the issue.

@VincentKen I checked and this increase in CPU usage was not triggered by a phone call in my case.

I suspect that it must be some system process that is causing this issue, since no app is indicated as the culprit in the battery monitor or in Gsam.

> I suspect that it must be some system process that is causing this issue, since no app is indicated as the culprit in the battery monitor or in Gsam.

That's the same conclusion I came to as well. I suspect that poor 5G connectivity in my areas has something to do with that, but I have no proof. In any case, I see no difference between larger 5000 battery on A54 and my old S22 with 3700 I'm trying to replace (cause I wasn't happy with the battery life) - they both seem to last about the same time. Not happy. Sending it back to Samsung.
