A5 2017 SM-A520F high stand-by battery drain issue - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

I have the galaxy a5 2017 SM-A520F i have a bad issue where something is keeping the phone from going into "deep-sleep" mode when the screen is off.
This results in battery going down about 2% per/hour, so battery will go dead with in 2-4days when its not been used.
I have no sim card, Bluetooth, WiFi, nfc all off, areoplane mode and in battery saver mode.
I have tried a few xda custom roms, android-10 with latest twrp & rooted, and google account activated. But also drains if i reset and flash the rom and dont add an account.
I have reformatted and reset all partitions multiple times, no sdcard loaded.
With my old android7 stock rooted rom, i would get a month of standby.
Attached is a Screen of BatteryGuru.
Looking at the attached pic I see mmc2_detect wakelock is going for most of the time, web says its caused by a bad sdcard or internal storage, but i have formatted /data and /system multiple times, and i have no sdcard.
I know that old Samsung phones have the issue with the internal storage going bad, and getting high error rates, could this be causing it?
Whats that gnss_ipc wake lock?
Could it be due to my Australian phone not working with international roms? i also had the same battery issue with my old s7.

S4 Mini Battery life

Hi all fellow forum members! It was about time to retire my old Galaxy S2, and i decided to buy a S4 Mini. About the same size, better specs and everything. But i dont like the battery life at all. I dont think its normal for my battery to discharge 20% over 8 hours at night. Does anyone have the same problem? I have been trying different approaches. I installed Snapdragon BatteryGuru, put the phone on power saving mode all the time, even switched 3G off, although without 3G there seems to be an improvement, but I'll let you know how's that going. So my concern is that i might have a faulty device.. or software.. idk.. when i had crazy discharge syndrome on my S2 i just changed the kernel and/or the ROM. Any advice or opinions on the battery life of the S4 mini will be welcomed and appreciated!
I don't have too many battery problems, I guess. My phone has been off the charger for around 10 hours - and the battery has dropped to 85% - which I think it OK. I've sent some text messages, checked e-mails, used WhatsApp and had a few phone calls, not exceeding 10 minutes in total. Oh, and the GPS is on 24/7 for now, but I've just got the phone rooted, so this will not be the case any longer. The phone says it still have some 7½ hours left - which wouldn't be enough for an "all nighter" tonight.
I have disables many of the push notifications, which might be the reason why I think it's a fair battery life so far. I used to have the SGS2 as well, which lasted around the same as this phone I reckon. The biggest hog is the Google Services/Framework that takaroundes up 25% of the battery usage at the moment.
I have though of having getting an extra battery for this phone, as it's always nice to have one charged.
My I9195 uses about 3% during night (7 hours, 3G data and wifi off). Try to use an app to see wakelocks used on your device, e.g. Wakelock Detector or Better Battery Stats - they might provide you with some hints to apps that keep your mini from deep sleep, which can cause the battery drain.

If it's an I9195, can you try to disable NFC and see if it improves?
My biggest drain is the screen. The device lasts about as long as my friend's S2 (we were playing a coop game together) and then surfed the net over 3G for a while.
We both scrambled to look for a nearby charging socket at almost the same time
Thanks for your replies guys! I will try those apps and report back. Wakelock already found one of my apps that has awaken the phone 1200 times.. shieeeeeeeet.. hopefully now that I have disabled it things will go better..
Hi all! I have found the source of my battery drain. It's Google location services. Turns out it's a common problem on android 4.2.2. I tutned off Google location an I my phone drained 2% over 8 hours. Sync, wifi and 3g were also turned on. There is a fix over at the nexus 4 forums, but it requires root and I don't know if it will work on our galaxies. If you have root, google nip wakelock fix, try it and report back.
I had battery problems on my s4. Turns out it was the SD card. Removed it and battery improved. In the end I had to change it for a new one.

Which one did you use? Sandisk 32GB?
I got an S4 mini for my gf with that card and it has terrible battery life.
The battery drained from 100% at 7 in the morning to 15% at 5 in the afternoon...
That's surely not normal...
Edit:
I noticed that the "media" service took up almost as much cpu time and power as (active for 1,5 hours) as the mobile connection.
I suspect, that some corrupt media files or whatever kept the service alive, which tried to scan the DCIM folder over and over again.
I checked the SD Card which was full of almost 5GB of old pictures pictures which for some reason couldn't be deleted because of "unknown errors".
So I took the SD Card out and put it in a card reader, to back up the files. Then I deleted the files, put the card back and formated the card.
Then I copied only some of the new pictures back into the DCIM folder... I'll see tomorrow if that helped.
Battery Drain
Hi iconata,
Can you let me know how to "disable" Google location services, which you observed as the source of battery drain? I believe I have disabled it but the battery drain issue still persists.
And FYI - the following is the message I wrote to Samsung and am waiting for their test to validate the result of my S4 Mini. Based on what Samsung told me, the Safe Mode calls out same phone settings as Factory Default, but it seems the following test cases did reveal different resutls from what Samsung told me...
Message to Samsung
-----------------------------------
Hi,
Thanks for advising to check battery under Safe Mode. The following is the 3 test cases I have done but I still have BIG battery drain issue with my S4 Mini.
All the test cases were performed under same conditions:
1. 3G on
2. Power Save Mode on
3. Standby for 8 hours overnight, from 12:00am ~ 8:00am
Test Case-1: All the extra apps installed
- Battery drain: 3% per hour (as I already reported)
Test Case-2: Safe Mode; long press volume-down key, with Safe Mode shown at lower-left corner on desktop
- Battery drain: 0.7% per hour
Test Case-3: Factory default settings; reset to Factory Default setting; all the data were deleted and no extra apps were installed; the phone was back to the original Factory default setting
- Battery drain: 2.9% per hour
Test Case-1 and Test Case-3 almost came with same battery drain issue at same drop rate, so those extra apps installed for Test Case-1 shouldn’t have contributed to this battery drain issue so significantly. However, looks like Safe Mode and Factory Default were very different, although you thought the conditions of the 2 should be same.
I still have battery drain issue even after rolling back to Factory Default Settings, and I cannot live with Safe Mode. Please help.

Hi pudin! You can turn off Google location services from maps app. Go to settings->google location settings and uncheck allow Google to use your location. And to further improve that you can turn gps off, and turn it on when you need to. Yesterday I decided to root my phone because greenify was asking for root permission and everybody was putting the good word for that app. Turns out it's a total croc... you can hibernate downloaded apps, but you can't do the same with pre installed. 0 use. Further more I started to receive an annoying notification that my phone's security has been compromised and it needs to reboot. Got angry, downloaded an official firmware from sammobile, preinstalled, turned google location services off and got this pretty decent battery life. Screenies are below, feel free to post your thoughts. Please note that I keep BaterryGuru and PowerSave on at all time.
Battery drain
Thanks for prompt feedback iconata! Now I can confirm the Google location services have been disabled on my S4 Mini. Also, I don't enable GPS unless I need it so those battery consumption numbers were tested without GPS running in the background. I got the call from Ssmaung tonight telling me my phone consumes more power than what they tested, so I'll return it to Samsung for further diagnostic tomorrow. Will keep you posted if any update.
BTW, I'm not that kind of guy brave enough to root my phone like you guys...

battery drain during standby
Hi,
Checked the image you posted and it looks like you were still doing something such as making calls and playing game over night. Your 3% power consumption per hour is similar to mine, but in my case Cell Standby and Device Idle are the 2 major items consuming the power the most over night, when the phone really enters the standby mode. Try to have your phone enter the standby mode without doing anything over night and check if the result is still the same.
strange thing... my battery was showing 16% left.. and went dead..

New FW update that improves battery drain
In coincidence I got notified of a FW update just yesterday night, one day before I sent my phone into Service, and it did improve battery drain significantly, from 3% to just 1% per hour over night after I checked the phone this morning. You guys may want to check the update as well, and I'll test my phone again tonight.

Which firmware?
I flashed the pre-rooted MG4 (over the stock MG4) yesterday, wiped the phone and froze all the samsung bloatware stuff.
That thing is still draining about 4-6% per hour while just lying around untouched. The phone is in power saving mode.
new test factory reset, all bloatware removed, just whatsapp is installed
screens
http://db.tt/nZFb2QKa
I still have 1.7% battery drain per hour I think is still bad
GMS arena seems to be the only site mentioning that issue:
Unfortunately the higher than average battery drain in stand-by mode prevented the Samsung Galaxy S4 mini from getting an impressive overall endurance rating. Even so it did more than well and if Samsung improves the stand-by time with future firmware updates, it might be one of the longest-lasting smartphones on the market.

Android System is using more battery than my screen.

Why is my android system taking so much power all of a sudden? Worrying.
Welcome to the sad party We have been discussing this in the OTA update thread as well. I've never had Android even close to Screen usage before. Now it's constantly there. And sadly no root for greenify or wakelock viewing.
Mine just started this after a very long charge. Plugged it up at like 9:00 am and it just finished about 10 minutes ago, very strange. It seems to be going back down to normal though.....
It's been higher since the last OTA update. Hopefully it will be fixed when lollipop gets released.
That happens to me on the original build maybe once a month. I just restart my phone and it goes back to normal.
Android System battry drain after OTA update
I haven't read through the other forums, so forgive me if I'm suggesting something that's been suggested elsewhere, but I was able to fix mine by disabling HDVoice..
Settings>Data Usage>Mobile Data>Enhanced 4G LTE Services
After I unchecked that I'm back to where I was pre-OTA.
All of you having Android System running at high %'s, can you answer two questions?
1) When you go to Settings> General > Battery and tap on the graph, does your Awake graph show as mostly awake (solid blue lines) when the screen is off (no lines next to Screen On)?
2) Do you have an external SD card in your phone?
I'm asking because I'm also having high Android System battery drain. My phone is also always "Awake" according to the battery graph (in other words, it isn't deep sleeping, so my battery is draining faster than it should). I just removed my external SD card for a while and now my phone is magically deep sleeping. Well, obviously not using your SD card is not an option for many people... myself included... all my music is on mine! So I'm trying a few things to allow me to keep my card in and to have my phone deep sleep. I'm just wondering if there's any similarities between me and anyone else.
UPDATE:
OK, so what I did worked.
If you have an external SD card, then do this:
1) In Settings>Applications>SD Card, I moved any checked apps to internal storage.
2) I then copied all my music, photos, videos, etc to my computer.
3) Then, with the SD card in the phone, I went to Settings>Storage and formatted the SD card.
4) I then copied the files from (2) back to the card.
After that, your phone should not only sleep better, but Android System should begin to move down the battery usage list after many hours. Just over night, it went from about 38% usage to 20% usage and is now #2 on the list. Cell Standby is now #1. By the end of the day, I expect it be even lower.

And i haven't tried the sd card one, although i've gotten a new one.
Anyone try this with success?

It worked for me (obviously), but it wasn't exactly meant to be a solution for everyone. Eventually, Android System became the highest drainer again, but on Lollipop, it no longer is. Again, that's for me.
Try removing the card and leaving the phone asleep (screen off and not doing anything) for a few hours. If the awake time decreases dramatically, then it may be the SD card causing problems.

Maybe is battery wrong.
There may be a hardware issue. Did you bring it to the Samsung service? You might get a replacement...

[Q] Why Battery Draining Fast?

I have owned this phone for about 3 days, but I have some battery issues.
I attached 3 pictures, and on the first picture, you can see there appears to be no wakelocks, but on the 2nd picture, the Android OS used the vast majority of my battery life, and the 3rd picture, Android System has a lot of "Wake Up Device" (i don't know what the number means is it minutes?)..
I have uninstalled/disabled most of the apps I don't need, and have the brightness set to low, and on airplane mode with all sync off, and zenmotion turned off, and this still happens. I lost about 11% battery overnight with this problem. It seems like when I am using the device, the battery drops a percent every minute even when I am just scrolling through the Settings.
I only used about 1 hour screentime on this phone and the rest on idle.
I already installed both system updates.
Does anyone know why this happens? I know there is a memory leak problem, but I saw on another thread other people don't have that bad of a drain anymore...

I've got here two brand new models, which differ only for touch and battery version (Z2C3 01040005 1525 and ... 1526)
The 1526 doesn't show any drain. The 1525 does, as of its very first boot. I tried keeping same settings of course.
I'd like to point out that when connected and charging it shows big steps like going from 63 to 72% and it also reaches 100% in less than 60 mins.
When disconnected the discharge path exhibits about 1:15min of operation.
May I suspect the battery is defective?
PS: after a factory reset from recovery seems have fixed the problem for now at least...

When you tilt your phone app icon adjust to the tilt, yes looks cool until you realize how much battery you could save by leaving then static and not constantly running a fDucking tilt sensor.

Sim Management killing battery any help??

Hi All, after all possible ways to fix my P2, I am getting little angry, as thanks to help people here, I sourced full S233, and done full format and fresh installation, but still no any ringtones or sounds available, no problem, used backup form Z2, and this should be covered, media was high on battery drain too, no problem removed sd card, find out something is not right, as media gone back to normal, backing up 80gb of data a reformatting sd card, but what is wrong with sim management - hammering battery heavily, on gsam pro - showing 75 % of battery consumed by combined app CPU !!!
What is could be???? Tried sim 1 and sim 2 tray no difference. I know there is bug which keep Phone idle high, but this is nothing against sim management, anyone with any suggestions??? Many thanks..

I am now experiencing the same thing. Could you please elaborate?
I just switched devices and transfered the content from my daily driver P2 to my spare P2 via Nandroid/TWRP.
I think I've had this problem before and that it had something to do with using airplane mode for an extended period of time.
