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.

Hey XDA friends. I got the Verizon HTC One a few weeks ago and battery life started out fantastic. When I put away to go to sleep it only lost 7% all night with GPS on and wifi on and all that and I was astonished. However as time went on I found those results kept getting worse and worse until I was draining 30% in a night. I went and uninstalled battery guru and now I only drain 12% a night. Some nights however I still lose 20% in a night with sleep mode on. How do I check what keeps waking my phone up and draining my battery. I'm afraid this will affect my phone's battery in the long run. I will start disabling GPS at night but I wish I still had that 7% in a night. How do I check what is messing with my phone???

go to settings/power/usage. this will tell you which app is using the most of you battery. also you should never have gps on while youre sleeping. you might also want to turn off auto-sync and then re-enable it after you wake up. you can create a widget to do just that. if you need help with that, just let me know.
Turn data Wi-Fi and gps off lol.... You are asleep

Do you use blinkfeed, that will kill your battery pretty fast. Even if you don't think you are using it, go check and see if it's syncing anything in the settings. I thought mine was turned off, but then I logged into facebook (turned sync off in facebook), later I found that blinkfeed was syncing it anyway w/out my knowledge.

You can go into settings and make sure everything is unchecked. Mine had several checked by default and it was draining battery.

Update: Battery only drained 10% last night with GPS off, Blinkfeed never updates on its own and all social networks are checked off (I don't like my social networks on Blinkfeed) other than that though everything seems to be in check. If anyone else has anyway to improve that 10% let me know (by the way the 10% was drained during 9 hours of constant sleep I went from 77 to 67)

Really, 1% per hour on standby with cellular radios on is pretty acceptable. Depending on signal strength, the radio could be pulling that just to maintain a connection to the tower.
Thanks everyone!
With GPS off, Sleep mode on, and NO BATTERY HELPER APPS (Battery guru was diminishing my battery life) I got a record breaking (for me) 4% loss in battery life during my 8 hour night's sleep, not bad if I do say so myself, after that my battery has been a lot better. I wish Verizon would give us HTC's battery saving software back but let's not ask too much of Verizon or they might give us timely updates.

Glad to hear this!!
those battery saving apps are so pointless IMHO, it's just another app and if coded incorrectly will do exactly what it did to you, destroy your battery that is working fine. very happy you can now enjoy your phone the way was designed to be!

Hey..I had the same problem so...first download wakelock detector from play store..after installing jus use your phone like as usual..after 4 to 5 hrs or right before you charge your phone, open the wakelock app and check what's waking up your phone during sleep..for everyone it seems the battery is drained by Google services ..the main culprit being the location services.. so switch off the location services in settings..and also in Google maps, go into setting and then into Google location settings and make sure location reporting and location history are disabled, make sure they are unchecked.. that's it..restart the phone..fully charge it and test it out ..and DON'T use any battery saving apps ..and also uninstall wakelocker app after your battery life is back to normal..I'm an average user and I unplug around 9 in da morning and when I come home around 6, I still have 65% left..I don use facebook .. heard even facebook app is major battery drainer....you jus have to tweak and play with settings till you find your desired battery life expectancy cos everyone uses their phone differently..and we all have different apps so the main thing is to find out what's eating the phone battery most...I'm just pleased with my decision in picking HTC ONE over galaxy S4
similar problem here....google services is killing my battery (relatively). location is part of it, but google hangouts is also going crazy (watchdog alerts me to excessive usage....over 50%, but hangouts was at 100%)
i was spoiled on my g-nex, where i left wifi, bluetooth, and GPS on 24/7 and could easily go 24 hours. now i'm lucky to get 12 (with about 1 hour of screen on time).
I'm hoping things will sort out, device is only about a week old, but google optimized location usage (iirc) such that it isn't supposed to constantly ping and kill battery. we shall see, i guess.
I'm not sure what the problem could be but I'm just gonna say that yesterday I got around 18 hours of battery life with over 5 hours screen on time which I consider awesome battery life.
I'm stock, so it's definitely possible to get good battery life.
10 percent overnight? Thats not that great but not horrible. My dna is running carbon (android 4.3) I use tasker to turn off autosync and data/wifi and put it on silent at whatever set time I make it. My phone drains about 5 percent max overnight, usually a lot less.

you can turn off updates in facebook and its not bad, but yeah if you have autoupdate on, it can kill the battery.
as far as the OP, I don't get why you don't charge you phone while you are sleeping. Seems like the perfect time.
Turning GPS off shouldn't affect your battery life. If you're not using your phone, the phone isn't going to use the GPS for anything. So it shouldn't be using your battery. The culprit is usually an app that is wakelocking your phone. So you need to find which app it is that constantly wakes your phone from deep sleep. Turning off autosync would help a bit if you are really paranoid. The big thing that hurts our battery when the screen is off, is the LTE radio, but most people are connected to WiFi when they sleep so it's not a big deal.
Just an FYI, turning off GPS has been ineffective since 2.2 Froyo. When Gingerbread 2.3 was released like 2+ years ago, it allowed for the GPS to only be used when an app called for it to be used. Otherwise GPS will not do anything unless you pull up an app that calls it to do something.

I am running on android kit kat 4.4.2 (not rooted) Since last update Google play services keeps my phone awake even when phone is in sleep AND in safe mode. Like I said, I was using my phone in safe mode for twelve hours just to be sure that none of installed applications is not draining my battery. When I went to sleep last night battery was at 76% and after 6 hours battery was at 11%, when I checked battery history, wi-fi was off while phone is at sleep, "network signal" line was solid (as it suppose to be) and "keep awake" was solid blue also and it was running for 7 hours 16 minutes, straight (which is NOT suppose to be). And imagine my surprise when I saw GOOGLE PLAY SERVICES among running apps exact period of time!
It is obvious that Google play services drains battery. What can I do to prevent mentioned app to suck out life out of my battery and still to be able to use application that needs Google play services.
Thank you in advance.
I forgot to mention that I am dealing with this problem 15-20 days already and that I tried almost everything. Location is on gps only, wipe cash in recovery, remove battery, battery calibration, right now running in safe mode.........etc, etc, etc

Hi
have you disabled google play services ?
or you can try the following Google settings >location >location mode >choose battery saving mode or device only
battery saving and device only should reduce battery drain if you have to have gps on, otherwise shut gps ,Google play services can still function without gps .i think high accuracy while more accurate it is not yet optimized for day to day use yet
The Google play services affects most devices which have kitakt
Several of my coworkers have this phone on Rogers. They have had this problem for years. The phone stays "Awake" all the time, even when the screen is off.
I have the same one but on Bell. It worked fine for about 2 years. All of a sudden this week I have the same problem as them. Phone stays awake all the time and battery now goes dead in ~4-6 hours instead of 2-3 days when not used.
Very frustrating. Any known fix is appreciated.
Hello! I've been lurking around trying to solve my battery drain issue for two days without success. I have a d2att with severe battery drain, where battery would last for around 2 hrs MAX before shutting down at 40%. This was apparently an issue before (my brother was using it) when it was on stock unrooted 4.3. I installed Carbon 4.4.4 to look for improvements.
Symptoms:
Rapid battery decrease during use
Shutoff at 40% (when rebooting it would show 0%, when charging it will start at 40%)
Constant wake (I believe from the systemupdate wakelock that is unstoppable)
Feels warm during short times of use, cool when standby
Attempts to fix:
Using GSAM to monitor battery drain (just installed Betterbatterystats, will update with that info later)
Installed MyAndroid Tools and Disable service to stop systemupdate and checkin services
Autoruns to stop all systemupdateservice receivers
Dalvik cache wipe to try to fix the 40% shutoff
Privacy guard to turn off keep awake for Google play services and Android system
Privacy guard to turn off location for GNow
Have not done:
Replace battery (just ordered one that's coming in two days)
Clearing batt stats, as apparently that doesn't help
Factory reset, as it's a pain to setup again (Should this be next?)
Greenify
Xposed
I am just generally confused at this point at whether systemupdate service is turned on or off, or how to solve that, or if that is even the main problem, and what my next steps should be. I'm not an expert and can only understand half of what's going on, so any advice is greatly appreciated!
*Update: It seems that the phone is able to go to deep sleep (~50% of the time). When I use it just 5 minutes for texting, the battery can drop 5%. After reading from another thread, I re-enabled systemupdate services from Disable Services/My Android tools to see if that would solve the problem, and it looks like it is not hogging wakelock anymore; however it does revert on boot, similar to this: forum.cyanogenmod(.)org/topic/96459-systemupdateservice-wakelock-on-cm11-m7-massive-battery-drain/
Update 2: I flashed Liquidsmooth 3.1 stable instead. This time I used autoruns manager and wakelock blocker (included in liquidsmooth settings) to disable the services, but systemupdate service still manages to run, so I have to disable the block to somehow make it stop with every boot. Once that is fixed, deep sleep functions normally, but now the new problem is that Chrome browser app seems to be stuck in an AudioMix wakelock. I uninstalled Chrome updates and this seems to have fixed that issue, however battery drain is still severe (5%/2min) during active phone use. No application stands out in constant wakelock anymore, so I'm suspecting it may be the battery itself? I will switch to a new battery tomorrow to verify.
Update 3: Well since no one bothered to help, I will just post this for future reference as a log, since I solved the last part by the battery switch to an Anker battery. The phone still gets hot, and I still have to manually deactivate systemupdate service on every reboot, but now it runs for "normal" times 5-6hrs (heavy use).
To be honest, it sounds like you had a failing battery. It happens.

After reading from another thread, I re-enabled systemupdate services from Disable Services/My Android tools to see if that would solve the problem, and it looks like it is not hogging wakelock anymore; however it does revert on boot, similar to this: forum.cyanogenmod(.)org/topic/96459-systemupdateservice-wakelock-on-cm11-m7-massive-battery-drain/
Update 2: I flashed Liquidsmooth 3.1 stable instead. This time I used autoruns manager and wakelock blocker (included in liquidsmooth settings) to disable the services, but systemupdate service still manages to run, so I have to disable the block to somehow make it stop with every boot. Once that is fixed, deep sleep functions normally, but now the new problem is that Chrome browser app seems to be stuck in an AudioMix wakelock. I uninstalled Chrome updates and this seems to have fixed that issue, however battery drain is still severe (5%/2min) during active phone use. No application stands out in constant wakelock anymore, so I'm suspecting it may be the battery itself? I will switch to a new battery tomorrow to verify.
Update 3: Well since no one bothered to help, I will just post this for future reference as a log, since I solved the last part by the battery switch to an Anker battery. The phone still gets hot, and I still have to manually deactivate systemupdate service on every reboot, but now it runs for "normal" times 5-6hrs (heavy use).

theres an xposed app called amplify that helps to block some wakelocks , startups and alarms. it might help.

Hi, I recently got my S9 but however lately I've been getting idle drain. With mobile data off, I lose about 2% every 2 hours and with mobile data on, I lose 4% every 2 hours. I have GSam installed and used ADB to give it permission for battery stats. Below are screenshots

It seems to be from IMS service. I read that it can be from either WiFi calling or volte. I do not want to turn off either. Had anyone else experienced this? I still have good battery but this idle drain isn't normal. I haven't left my phone overnight so I guess I might try that tonight and see how much it drains
Hi there,
I am re-opening this old thread since I am facing the exact same behaviour with my new S10+. Due to IMS wakelocks, my battery drains 30-40% overnight (while I'm sleeping for 7 hours). If I put my phone in flight mode, it loses 1% overnight. Did you manage to find a solution afterall? I really hate having to put my phone in flight mode every night. Thanks in advance :highfive:

Did you ever find a solution to this? Experiencing same problem now ...
Hi ... did any of the posters above find a solution to this issue ?
I am stuck at exactly the same problem: The phone (S9, stock-rom) drains approx 20% over night, doing nothing. Reason (according to GSam Battery Monitor) is the high power consumption of Apps > Android-System > 48 mins (264 count) wakelocks caused by ImsService.
If you look at the picture of batter usage in Gsam you clearly see, the phone stays active all night and barely sleeps/dozes :-(
What I already tried, without any effects:
- clearing cache of all "IMS*" Services in App Manager
- wiping cache partition
- disabling AOD (Always On Display) and VoLTE Telephony
- removing and re-adding google account
I am a little clueless and would like to avoid a factory reset as especially all those nasty "push-tan applications" will most likely need a re-authorization :-(
I'd heavily appreciate any hint.
After a long journey it seems that I found a solution: At least on Android 10 there seems to be a bug in google location services. If you disabled location history, the API requests are still made but get stuck each time (every 60 sec.) and keep the phone awake instead of returning to sleep.
The "bitter" solution was to turn on Google Location history again ... and suddenly the drain ends, as the detection and transmission of the location is ways faster, than letting the die in a timeout ...
