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

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.

[Q] Rapid Battery Life depletion during sleep

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.

New Moto 360 battery died after 3 hours!

I've just changed from a Gear Live to a Moto 360 and after charging and syncing the battery died after three hours! Horrendous. Someone please advise! My gear Live with the same settings never did this.

Hi,
I just received a Moto 360, and I know what you're going through!
I've gone from 3 charges a day previously, and today the watch is reporting I have almost 2 days remaining of charge.
First, FULLY cycle the battery. Leave it on the stand over night, run it until it turns off (if you're in a rush, ambient display, full brightness!). Then, full charge to 100% and leave it for an hour on the charger once it is full.
After that, do a factory reset on the watch (in settings). In Android Wear on phone, use the settings menu to resync your apps.
Do one more full discharge and full charge, and you should be sorted.
If not, use the Watch Battery section of the wear app to identify problem apps. Before today, I had never seen a "watch idle" entry, because an app was holding the watch awake. Identifying and removing that app has solved the rest of my problems.
Hope all this works. Some of the steps seem/may be unnecessary, such as the factory reset, multiple full charge cycles. However, I speak from experience that they do work!
Edit: Do be aware that the charge cycles where you do a factory reset and sync will drastically drain the battery, giving the illusion that the problem is still there.

So which app was that. Could you be specific please? I've had my 360 since October and had no issues with battery life until about 2 weeks ago and now it can't make it through a work shift all of a sudden. I've seen the 'watch idle' and the android guy with no title in the battery stats (as well as 'Bluetooth', which is mind blowing) as the main drains but I can't figure out which apps need the boot. Thanks in advance for the help, this problem is driving me crazy!

For me it was WeChat. I didn't even know it had a wear component. However, using Wear Battery Stats (available on Google Play) I noticed that there was a missing icon under "app activity" because it had updated that day. Tapping on this blank icon told me it was an activity belonging to WeChat. Using this, I deduced that was the problem app. Removing it seems to have solved my issue. I'd recommend a similar process, although I only found this app on that day due to it updating, so you may struggle. I get the impression the standard of coding of wear apps so far is pretty shoddy, I don't think not providing a package name and icon is unusual or specific to this one app.

Thanks for the reply. I don't use that specific app so no luck there. Good call on Wear Battery Stats though. I actually already use it but I'll use its stats this time instead of the standard wear stats. Thanks again, hopefully I can find the culprit, been having issues with my phone battery as well recently too.

fyi - i haven't tested this since it happened, but i disabled BT on my phone (just disabled in settings, without disconnecting the wtch first) and the watch drained itself in probably about 20-30 minutes. When I finally got it charged, it said BT took everything.

When I was having app issues, I also noticed very high bluetooth consumption. This could likely be a poorly coded app constantly trying to ping your phone for data and receiving no reply as it is not designed for a scenario where your phone is not connected.
The alternative of course is defective hardware.
A step I did not include in my original post was that I also clean-flashed a new rom on my phone. I felt this was due to a unique problem that I had (bluetooth problems in car also) but nonetheless thought I should mention that too. It's hard to be sure which step exactly cured my watch.

Same was happening to me, after several master resets and trial and error, i found that on my Samsung s7 edge i had my watch set as a trusted device so when it was connected to my phone my device would unlock without passcode. After turning that off, battery life is normal again, 24hrs plus. I think the constant bluetooth checking to see if it was attached drained battery extremely fast, hopefully this helps someone

[TIP] Factory reset after 5.1 update to fix battery life issues

A lot of us SW3 users are having battery life issues after the Wear 5.1 update. My Smartwatch 3 went from 50% to dead in 90 minutes without using location or Wi-Fi. But after a factory reset (and long resync) my Smartwatch 3 is lasting longer than ever with Ambient Mode still enabled. I recommend factory resetting (the only things that will be lost are preferences and sideloaded apps) and disabling Wi-Fi after setup. If you can tolerate it, disable additional features like tilt wake and GPS (location). See if battery life improves and reenable useful settings after a few days.

Trick didn't help me. After 2 resets battery life is same. Drainig battery is here. Now for 2 days I am looking what is draining battery.

Ive done 2 factory resets since the issue started.
I've also turned off gestures, GPS, wifi and cloudsync.
Nothing seems to make a difference...

I think that some apps are not optimized for newest version of Android Wear, my Smartwatch after update has problem of battery draining, I've done 2 resets but nothing, then i uninstalled all apps and installed 1 app every 4-5 hours to find what causes problems. For now I found WatchMaker Pro that causes battery draining. Now using my watch normally, with wifi on, wrist gestures and some watchfaces installed from yesterday at 6 AM, today at 4:30PM i have 35% of battery, is not so bad!

I suspect this might be true. For me, Muzei app and possibly FORM watchface suddenly consumed 400mb of cellular data within minutes and sent my battery diving. Uninstalled both apps and battery life has been back to normal, even within Wi-Fi turned on (albeit rarely utilized since I'm hardly away from my phone).

Battery life issues after 5.1.1 update

I had good battery life before 5.1.1 despite many apps loaded including WatchMaker Pro. Was able to get through end of day and then some.
After 5.1.1 update can't get more than 7 hours. I tried completely resetting watch, removing/reinstalling Android Wear/Moto apps from phone and clearing BT. Tried removing many apps, turned off WiFi, turned off card flip, ambient off, even turned off flip to wake which I had on before. There are less battery munching things installed and more functions turned off yet much lower battery life.
Battery Level indicator shows...
- Android Wear 8%
- Bluetooth 6%
- Android System 4%
- Screen 3%
I saw post about clearing everything off phone and starting over, which I've done.
Any suggestions?

Edit: Based on responses below, it has been fixed.
Here is exactly what I did that solved my battery life issues after 5.1.1 update. I don't know if all steps necessary but is what worked for me...
- Go to Android Wear app on phone, Settings>Moto360 Connected>Forget Watch at bottom of screen
- Phone App Manager in Settings, Select Android Wear - Clear Data, Clear Cache, Uninstall App. Also uninstall Moto Connect app.
- Check Bluetooth, unpair watch if still there. Turn off Bluetooth.
- Reboot Phone (Do this, I missed this step and had issues)
- Do a factory/hard reset on Watch from Watch Settings
- On phone, turn on Bluetooth after rebooted.
- Install this version of Android Wear (this may not be required but is what I did)...
http://www.apkmirror.com/apk/google...roid-wear-1-1-1-1956917-android-apk-download/
- Setup as if new watch
- Check battery level over time and hopefully 'Watch Idle' is on top of list
- After confirming battery drain resolved....
- Goto Android Wear, Settings>Moto360 Connected>Resync apps
I now get well over a 24 hours battery life with many apps installed and complex Watchmaker Pro face - everything turned on except WiFi, ambient screen. Watch Idle shows as top item in Battery level screen.
I eventually let Android Wear app update under Google Play and all was fine. It may not be necessary to install older version first but is what I did.

I have had the same results. I used to sleep with my watch on and the battery would drain about 18% in 7 hours. Since installing 5.1.1, my battery life is much worse. This morning i woke and only had 2% charge left. Today I went from 8:30am to 2:30pm and had 39% charge left with minimal use, so it burns around 10% an hour.

Is there an app syncing data to your watch (Play Music) or anything? Here are my stats so far today:
- Idel 8%
- Android Wear 4%
- Android System 3%
- Screen 3%
- Bluetooth 2%
- Wifi 1%
(I had 4 other apps at 1% each that I did not list)
I have had my watch off the charger for 9 hours and lost 37% battery (4.1% and hour). The only thing I see is that your Bluetooth and Android Wear seem high, which would make me think there is some app syncing data to the watch.

Unninstall the Android wear APK that updated on June 18 on your phone, install the May 26 APK and deny the auto update feature, this worked for me.
With the update the watch lost 10% in 1 hour now it loses 10% in 7 hours
the link for the android wear apk is:

Thanks all. I reset watch again, installed older version of Wear above and rebooted phone (important step I didn't do before). Am now getting 24+ hours even with a complex Wacthmaker Pro face I created that shows heartrate/steps/weather and 10 other stats. Am happy camper again. Watch Idle is now highest on battery activity.

BTW, Android Wear updated in Google Play to latest version and still great battery life.

7 hours is great. Mine died in 45 minutes. I got up - took it off the charger - it was at 100% - 45 mins later it had 12% left and a minute later died. I'll see how it goes tomorrow but 45 mins of battery time for a relatively new device is insane. It says that 98% of the battery is used by Android Wear.

The battery drained in 3 hours of no use, wtf happened? any idea?

I posted exactly what I did to solve my problem in the second half of the first post.

Go to Android Wear app on phone, Settings gear icon>Moto360 Connected>watch battery
edit: Seems odd it's so deeply hidden but the reason is because they now support multiple Wear devices so you have to select which device you want to see stats on even though most only have one.

I just bought it today but my batery life is just horrible. I updated to 5.0.2 and I don't think I should install 5.1.1.
This is what happends:
- I charge to 100%
- after 1 hour its dead.

drop down on the watch or open the android wear app tap the gear at the top right then select moto 360 and there is an option that reads watch battery.

Since the update I can't seem to get to bed with the 20 per cent of battery I used to. I have tilt, ambient, gestures, wifi and auto brightness on. Should I turn off wifi or something?

Check battery level in Wear app and if Screen is high, it might be tilt, ambient, auto brightness. I'm not sure where WiFi shows up, maybe as Android System. I have WiFi turned off, would think it would be biggest battery muncher. Ambient also known to munch.

do you know how to remove moto heart rate software without root ?

I've been having really good luck with battery life considering. I lose about 3% an hour on Bluetooth and about 4% an hour on WiFi. I can't take my connected phone to work so I use another phone to create a hotspot. My watch spends about 9 hours straight on WiFi and I am having better than expected results. Tilt on. Ambient off. 180 min WiFi timeout. Stock rotate watch face. Auto brightness.

I've got no issues with the watch on 5.1.1, but my Samsung S6 has been hit hard with the latest Android Wear app... fk me.. I used to get almost 5 hrs SOT, but now its just on 3.5hrs..

I think the watch/software is just buggy. Like today I got out at 10AM and it's now 11PM and it still has 58% battery. The other day it died in less than an hour.
PS: Perhaps it should be restarted every now and then. Reminds me of old times with Windows 98. Restart usually fixed lots of problems.

After doing the whole process of deleting apps, resetting the watch and pair the watch to the handset the battery lasted 2 and a half days
