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.

Noticing your Galaxy S6 battery is draining too fast? This thread can help.
Part of the problem lies within a memory leak which is a known problem that Samsung is aware of and is reportedly patching in an upcoming update.
The other issue is Samsung attempts to load everything into memory and run several services in the background as well as hard loading the phone with bloatware.
Here is how I gained 30% better battery performance. Guaranteed
*Prerequisites
*Need to be rooted for every tip to work.
1. Disable anything you consider bloatware
2. Go to settings then application manager and disable both ANT radio service apps. You don't need this. Causes massive battery drain. Google it if you don't believe me.
3. Go to the app store and download "Servicely" from Franco. Paid app but worth the money...trust me. (Need root)
4. Once in servicely add running services and apps to your hit list, choose start at boot and run hit list while screen is off.
5. Reboot your phone. Give your phone a full charge and see the difference
Attached is a screenshot of realistic usage. I was on a poor lte signal for 9 hours and conducted several calls and used my phone moderately heavy. As you can see i got through my entire work day and still have 6 hours left at moderately heavy use.
Remember, this is realistic. I could have shown you a screenshot showing 18 hours left after only using it 1 hour. What I'm showing is a legit 9 hours of usage. Before I made these tweaks I would be at 10% battery or less after nine hours of the same usage.
Post your screenshots after 24-48 hours and let's see how much you are saving.
Follow me on twitter @bash_array
This will be great for those that have the battery drain problem when safe root is achieved.
I got good results just disabling all the junk apps without root.
Waiting for safe root.

Hi All
Disclaimer: I'm new to the forum so apologies if this is in the wrong discussion area etc!
I got my Galaxy S9 on Friday 9th, prior to that I had an LG G5 which is now gone. In the last few months of using my LG G5 the battery life was questionable - the phone would get hot (sometimes without even using it a lot) and the battery would drain by 30% an hour. I noticed, but didn't test fully, that Google Play Music seemed to really cane the battery and phone - i.e. was getting hot and draining quickly. As an example, I'd leave home at 7am taking it off charge at the last minute (100%) and get to my office at 9am and it'll be at 50% and very warm. Prior to that (can't exactly pinpoint when the drain started to really kick in) it would only drop to 85% - much more acceptable.
The G5 has a replaceable battery - 2800 if I recall . So I threw down £50 on an official LG site for a new slab of Lithium - slight improvement, but still terrible and warm. 55% instead of 50%.
"Right - time for a new phone" as I assumed that 2 years of app updates meant the CPU was lagging. Bagged a Galaxy S9 - today was my first commute into the office. Started on 100%, arrived at 55% with a 3000 battery! And it got super warm like the G5.
Most of that time I used Google Play Music, which according to AccuBattery the discharge speed was "33% per hour". Second was Google Chrome at 30% per hour (though I didn't use it much at all on the journey).
My question is - what logs can I check, or apps I can use, or something to find out what's going on? I need to test a few things of course to pinpoint the issue. If it helps - I restored from my G5 when I setup my S9.
seems like you might have have some options enabled in Google Play Music / chrome - that is keeping the phone awake
generally when you switch phones they apps and their settings get transferred automatically now - worth maybe uninstalling them for a day and see if you're still experiencing this issue
other than that it could be that your commute involves travelling thru areas of no signal where the phone keeps trying to find a signal - that can drain battery a lot

Thanks - I'll try that next time. Might also try a factory reset but not restore from the LG G5 backup to see what happens then.
how bright is your display? do you leave it on all your commute?
Got your wifi enabled which hunts for a signal even though you aren't using wifi? try turning it off. Same with location setting.
And how strong a signal do you have on your commute. Streaming lots of data on a really weak signal will kill battery, too.
Go into settings and see whats draining your battery.
Battery Drain Issue of S9 - Resolved
:laugh:Hi All,
I could resolve the Battery drain issue but not touching any other setting of the new phone by just disabling the backend data usage of all application expect few like Edge screen, Gmail, Flipboard etc... Now the android system power usage is back to 4-5%. Previously it was 21%-25%. So issue resolved. Need to find out the way to inform this to Samsung so they can identify which app is consuming full battery power.

Hi, i'm facing ridiculous drains too and factory resetting hasn't seemed to help. I'm trying your resolution, but I don't entirely understand you. Could you kindly guide step by step? also, if you mean going to optimise battery usage, when i go there and select the 'apps not optimized' all the apps there are greyed out therefore not allowing me to select them.
As above, in recent days, for no apparent reason I am getting a bad battery drain. After using GSam battery monitor & the in built battery stats, Android System is responsible for 33% battery drain!!!
Any fix or solution? I am rooted with recovery on 8.8.30 MIUI 10.
I do not wish to wipe or flash as my device is perfect in every way, only a battery drain from Android System.
Any ideas? Thanks in advance

Me too, always awake it never goes into deep sleep
The same thing happened to me and with the Gsam Battery I verified that I had in a short time thousands of calls to the LocationManagerService. After trying and testing I think that the time widgets that I installed (HD Widgets, Xperia Clock, ..) are due. I have taken them out and now my battery consumption is normal. Anyway, this must be a Miui bug. I spent as much with xiaomi.eu as with Revolution OS.
^ Thank you so much guys for the response, but this is so strange because it only started to happen many weeks after using the rom. It was fine as normal then suddenly this battery drain issue started.
Even tried battery hibernation apps/greenify, now difference.
Previously, I used to get 11-12 hours SOT, now only 7 max. Really disappointed...
After prolonged trial and error plus googling. I managed to finally fix my MIUI10 battery drain.
1. Under Settings>Battery & Performance, disable ALL smart scenes.
REASON: smart scene detection causes wakelocks. A MIUI10 bug.
2. Under Settings>My Device>All Specs, click Total Storage 5-6 times to get into Phone Info Testing menu. For both Phone Information1 and 2, set to your local band. Xiaomi.eu uses LTE/UMTS auto (PRL), while some users recommend LTE/WCDMA. [This setting persists until next reboot/airplane mode/network change, then you'll have to set it again. Leave default setting when roaming]
REASON: Default setting enables TD-SCDMA band scanning, which is only used exclusively in China. When disabled, will save some juice as network signal strength fluctuates.
3. Of course check Battery Use of your apps to make sure no rouge apps are keeping your phone awake in the background. Consider adjusting (a) Start in Background Permission, (b) Autostart Permission, (c) locked apps, (d) app battery saver status, and (e) toggle Developer Options>Inactive Apps

I wasn't able to find any setting called Scenes or Scenarios (saw that name used in another thread) on MIUI 10.3.2.0 global stable. When I open the Battery & Performance menu all I get is Battery Optimization, Power Usage, User Adaptive Battery, Choose Apps (for app battery saver), and Extreme Battery Saver. I also searched for them using the search function. Is this available on all MIUI versions?

Hi guys i have my pixel 3xl and my battery is drain too fast when i dont use it in night fo exemple a left him 100% after 6hours i found him 70%
I chek if thers is an app in background and nothing i Factory reset it 3 times and same thing
Let it drain down to about 10%, and then check the battery stats to see what is high on the list. I get less than 1% an hour, and have for the longest time. Running Android 11 since beta 3, and now official.
Hi! I got exactly the same thing with my Pixel 3 and got the same issue, it seems like our device cannot deep sleep. Here is my battery usage and wake lock on EXKM (Running latest Kirisakura, screenshot attached)
Also mine, last night it was 100% then this morning, when i checked it, its already at 95%. Also i noticed that my 3xl now is draining too fast, any tips on regarding this to save or extend my battery? Thanks guys
First week(nearly) after factory reset or flashing img your google play services should drain too much battery which is normal as settings are calibrated, usage patterns adjusted, small updates installed etc.
Most battery issues are related to some rogue app, bad signal reception(it does not need to be full bar, even selected frequency by carrier or phone) or confused google play services. If it is google play then root needed to find root cause(pun intended )
For my case a full day with 1h+ gaming and whatsapp, phone and other stuff 4hrs sot and generally less than %20 percent battery at evening to start charging. You should be happy if you are near this values.
Hi! Thanks for the insight, I'll try to wait until a week and going to post an update here! Just curious because I can't find any information about the kernel wake lock that constantly occurring on my new phone
Edit 1:
So after a few days of searching, I found out the one who cause the deep sleep issue was my modified settings for the Entropy (I modify it via EXKM), after I set it back to default the Deep Sleep issue completely gone and I can stay 0.2 ~ 0.3%/hr when the phone is Deep Sleeping
I hope my issue can help you, and try to reflash it via fastboot with the latest (Android 10 / Android 11) pixel image just to make sure that there is no corrupted data
