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.

I was wondering if anybody else had this issue or had any suggestions.
Battery life is normally great on the tablet, except every once and a while it gets stuck awake overnight. There doesn't seem to be a 3rd party app that is holding it awake, as Android system and OS is what's using most of the battery.
As you can see in the screenshot, Doze works fine and barely any better is drained, I used it briefly, came home from work and half the battery had been drained.
Thanks for the help
Not sure if it's normal but mine does the same.

I've seen a 30ish % drain sitting overnight a couple of times over the past 2 weeks. Can't seem to find a rhyme or reason for it.
I can't imagine it being "normal" since, with Wifi set to off while sleeping that the device should drain that much.
It's odd and happens randomly, I'm on the same page as you bluestang.
It happened to me once, at night it wastes a 15% battery.
I changed in wifi advance options to not maintain WiFi always awake, only in charge.

That's the setup I have though - so I get no notifications or anything when it's not on. Yet something is still keeping the device up.
I have *exactly* the same problem with an all new device, and with nothing but a game installed on it. After a reboot, if I let the Pixel C right there for a night, then it only drains ~3/4%.
Then I play the only game I have for 5 minutes, and let the device again for a night => it now wastes a 20% battery!
No idea what's going on... "Android OS" appears first in the list of app, but this does not help me so much to find what is actually happening...
The issue still appears even after a full reset of the system (I'v tried, without success).

Exactly. If I reboot the device and let it sit, doze works fine, the second I open an app, use it and put the tablet down, something hangs and keeps it awake. Always Android OS that is keeping it awake as well...
I have this issue too. Are you guys on xceed Kernel?
Whats really interesting even better battery stats Shows no culprit.
I'm on the stock-just-reset-again last version of the system.

I'm on stock - not even rooted
I'm on stock MM here as well.
Also, not sure if it a coincidence or not, but I changed this and haven't seen overnight battery drops anymore. In Settings>Location I changed the Mode from High accuracy to Battery saving. Since the Pixel C doesn't have GPS device, then why use it.
Like I said, not sure if it a coincidence, but battery life has been great overnight since.

So last night, I rebooted before I went to sleep, but overnight the battery drained from 85% down to 57% in about 8 hours.
I decided to check my location settings as per your post and found it was set to high accuracy, so I changed it to "Battery Saving".
I did nothing else(no reboot) until I checked my battery now about 3 hours later, it has only dropped by a further 2%.
Looking at "Battery Monitor Widget Pro" history statistics, it is clear to see that overnight the battery was draining considerably more.
It takes readings every 10 minutes and was showing between 450 and 275 mA being used every 10 minutes overnight.
Since I changed the location settings, most of the time it is 15mA with occasional jumps up to a max of 297mA.
Although this could not be classed as conclusive proof, it does seem to have had an effect, I will keep monitoring it to see how it goes.
Yep, I change that setting on the 19th or 20th and haven't seen any major drains overnight.
I think I may have found a winner with that little tweak
So far so good for me too. I don't know if it is related to the GPS settings, but no more inconsistent major drains so far.
if location services is on it can drain a good deal
Just to add that I had exactly the same issue on stock 7.1.2, tablet was staying awake and draining. Reduced location precision and now only a 2% drain during an 8 hour sleep which is a massive improvement.
Hi everyone
hope this is a good place for this. I just bought a brand new P2 and yesterday I was doing some configuring for it and updated it to 7.0 (S244 stock). I did wipe it after all the updates according to instructions on this forums. Before going to sleep I charged it to 100%, unplugged the charger and left the phone with all connectivity (wifi, lte, bt, nfc etc.) turned off. I expected 2-5% battery drop but when I woke up in the morning it went down by 25% (!). Also my wallpaper changed to black colour(?). Something's definitely wrong What can I do about this?
Power manager shows the system as the main source of battery drain.
Another thing I noticed is that the video (YouTube, VLC) and alarm sounds are stuttered, there is like 0.5 sec lag every 10-15 secs...
Please someone tell me if this is normal and what can I do? Should I do factory reset once again or maybe flash the firmware? Can that help?
UPDATE:
I have found that the cause of the baterry drain problem is the CPU, it does not go to deep sleep at all and CPU-Z shows that it constantly jumps beetwen 652Mhz and 1401 or 1689Mhz on all 8 cores (even with no apps in the background and all connectivity turned off). Please have a look at my screenshots from GSam Battery Monitor:

Clearly something is wrong, any suggestions? Please guys tell me something.
Is nobody else experiencing this? Does no one have ANY suggestions for me whatsoever? I did a factory reset, phone is still losing 1-2% battery per hour with all connectivity and screen OFF. So basically it loses per hour what it should lose during whole night.
Are you on Nougat or Lollipop?
Can you post up the system battery stats from the phone.
Which apps have you installed?
Try these...

Obviously the deep sleep is not happening in your unit. Let's see what is the root of this problem:
1) Settings > WLAN > cog-wheel icon > Keep WLAN on during sleep = Never.
2) Settings > Power manager > Battery saver > On.
3) Settings > Data usage > Data saver > On. Ensure zero apps is allowed to use unrestricted data when Data Saver is on.
4) Charge the device till 100% (do it before bedtime).
5) Turn on Airplane mode.
6) See the per hour drain the next morning. It should be between 0.1% to 0.3% per hour in the GSam Battery Monitor app (assuming you slept for 8 hours).
If the above result is true, meaning, there is / are 3rd party apps that trigger the wake lock activity. But which app(s) to be blamed? Please list down the apps list for us to test in our unit.
@Treboeth, Nougat (s244) as I wrote in the first post. Battery stats after the night attached below.
@azeemzuhair Thank you for your input. Im going to describe what I did. Yesterday I did the factory reset, I didnt install ANY new applications (except for Alarmy but I needed it and phone was losing same amount of energy without it). So the only apps that drain the phone are the system apps themself. Before going to sleep I charged the device to 100%. As for points 1-3 from your post both WiFi and Data were OFF as well as bluetooth and NFC. I left it for the night with screen OFF. These are results after the night (SoT 1 min., standby 9 hours, 22% of battery gone, so that gives approximately 2% discharge rate per hour). This is clearly terrible. Any ideas what next?

Airplane vs active SIM stand-by drain...
Airplane mode stand-by drain @ 0.1% per hour:
Single SIM Active mode stand-by drain @ 0.5% per hour:
Ok, so I left it in Airplane mode for the night and the discharge rate was 0.2%, that is some progress. After that I charged it to 100%, unplugged, disabled the Airplane mode and left it for 5 hours. Battery drain is due to SIM card and phone although they were not used and the signal was good. Everything can be seen in these screenshots:

My hypothesis is that the "Alarmy" app caused the wakelock. By judging at the Airplane mode, Alarmy still wakes the "CPU". You may try to uninstall it and monitor the energy consumption for the next 3 days...

Try "Network Reset"
Still the same? Wipe cache partition in the stock Lenovo Recovery.
Finally, hard reset is the last resort.
Thank your for your reply. Removing SD card fixed the SIM management drain but the "Phone Services" still drain the battery. I did the network settings reset and will see if it helps. As for cache wipe and factory reset I'd like to remind that the whole troubleshooting process started with factory reset so I dont know if that can help.

I decided to return this chinese crap, took Samsung instead, no battery drain so far. Thank your for your help!
I'm a really light user. I lost a little less than 2% every hour. Basically I use it as a purely communication device. Mostly check facebook messenger, my emails, and occasionally, browse facebook, reddit, 9gag or watch a short youtube video. I stay up about 16 hours on average and at the end of the day, I was regularly around 80%. If I left the phone unplugged overnight while I slept, I only lose about 6% over 8 hours. I was really happy with the battery life. I could very easily see 3 full days out of my phone off a single charge. This was before the Pie update. I tried both the Beta and the Stable once it released, and my battery life has suffered severely. I'm losing 6% every hour, even with the screen off the entire time. At the end of the day, my phone is in the red and has already turned on power saving mode. Android Pie has killed my Pixel 2 XL's battery. I gave it 2 weeks to "learn" my usage habits, but ultimately, I factory reset and even went back to 8.1, but I still suffer from battery issues. Battery usage gives no hint to the culprit. My phone has been unplugged for 7 hours, with 45 minutes of screen on time, and at 54% remaining battery life. Screen On time is the highest battery drain according to the system battery stats. I didn't have this issue until I installed Android Pie Stable.
I have no idea what could be going on, but could really use some help with this.
TL;DR: From 2% to 6% per hour battery drain on Pie. Reverted to Oreo and FR but still an issue. Advice?
Did you check if the WiFi scanning is turned ON? Settings --> Location --> Scanning
I feel its the only issue, nothing should drain your P2XL crazy if apps remaining constant factory reset.
-- personal experience.
I also use it very similarly to you and easily get 2 days with a single charge on Pie. During night my device drains 1 or 2 % only (wi-fi, bluetooth and 4g on), but I have wi-fi scanning off. Google location services are on (including Location Accuracy on). "At a Glance" is turned off but still using stock Pixel Launcher. No hacks/mods installed.
Same except I have at a glance enabled. I disable it 6 hours ago to test and didn't affect battery drain at all. Still losing 6% every hour. Location and scanning settings default except connect to open WiFi is enabled. Right now testing if connect to open WiFi and Bluetooth WiFi location improvement affecting battery drain.
Testing that now. Will report in a day. Heading to bed now. Gn
Does the phone charge all the way to 100%? Does the phone ever turn off by itself when low on battery ~10%? Install and run Accubattery. After a few charging cycles you will get a very close approximation of your battery's remaining capacity as compared with new in mAh. Battery capacity will be located under the health tab. The more charge cycles you monitor, the more accurate it gets, but it will zero in on a number pretty quickly after the first 2-3 charges. Could be the battery... stranger things have happened. This also assumes the user has fully wiped the phone several times going between DP's, Pie and reverting to Oreo.
Does the phone charge all the way to 100%?
- Yes
Does the phone ever turn off by itself when low on battery ~10%?
- Honestly, I don't know. I never let my battery get that low.

I changed some settings and now I'm getting 17mAh drain. Fixed.
The biggest battery sucker for me was having Auto-connect to open wifi enabled and fixing stuck sync tasks. It was preventing my phone from sleeping.
Great to know you were able to stop the draining, I think it might be of great help to other P2XL owners to know what were the settings you changed that fixed the issue.
What settings did you change?
I am having the same issue. I would be interested in hearing your changes as well. Thank you
Download and install Accubattery to monitor your mAh usage. Make sure you check your deep sleep percentage. By the sound of things, your phone is running hot when idle, so it's not sleeping like it should be. You can install Wakelock Detector Lite to see which apps are keeping your phone awake. Once you find out what apps are draining your battery, use the System battery manager in Settings to restrict battery usage for those apps. If that doesn't help, then uninstall the app (unless it is necessary to you). If an app isn't keeping your phone awake, then it may be your system settings. Turn off location scanning for wifi and bluetooth (in the GPS section). Turn off Wifi auto-connect to open wifi. Where I live I have pretty weak cellular connection. I opted to disable Mobile data always active in developer options (Go to about phone, and tap the build number 7 times, then enter your device password). While you are here, you can check Running services in developer options and see what you have running. Also, make sure your accounts aren't stuck trying to sync. If they are, cancel the sync and restart it. Depending on how far you are backlogged, this can take a while. If the sync still gets stuck, try removing and re-adding the account that is getting stuck.
After I restricted/uninstalled the misbehaving applications and tuned the device settings, I'm getting great standby time on my Pixel 2 XL. If I close all my apps before putting the phone back in my pocket, according to accubattery, I'm losing 15mA/h or about 0.4%/h. If I charged my phone to 100%, then unplugged it without using it at all, it would take 10 days for the battery to run out. It's pretty good. As someone who primarily uses their phone as a communication device and research tool, I'm a pretty lightweight user.
+1 What settings did you change?
Yes, please, don't keep us in suspense!
Just got a used one so trying to learn all about getting optimum performance.
Hello guys, yesterday I noticed an huge battery drain on my RN8.
The phone is new (received it on 18 December). I state that when I use it I always have 4G on (because right now I'm without wifi connection at home, damn my ISP) but of course sometimes when I don't use the phone I turn it off. I stay with GPS off, Google Assistant off, and still I notice a battery loss of around 3% every 45 mins, even when the phone is in standby, every 10-15 mins when in use (too much!)
And, as I use WhatsApp, I recently noticed that it is lirerally eating my battery, you'll see on screenshots.
For the charge, I always try to keep the phone from 30/40% to 80%.
What can I do? Are there some settings to improve? Maybe a way to manage apps working in background? I don't always want to stay on Energy Saving mode, or is it the only way?
oh that is a huge amount of battery drain, the Facebook app used to do that some years ago, and the advised solution in whatsapp make a backup of you data first, then go in to; settings, apps, and clear cache and data for the app. could also try reinstalling the app.
as you dont have a internet connection at home but you still have wifi, you phone/whatsapp might be trying to make backup but it can't cause of no internet. try change the settings in whatsapp to back over cellular aswell.

Hello buddy and thanks for the reply.
I haven't noticed any backup settings on: however I followed your tip and tried to reinstall WhatsApp, seems that now consumes are normal. I also tried to go on Settings -> Battery and performance -> Power save app -> selected WhatsApp and selected "limit activity in background" so maybe this is also doing its work. I know that I won't receive notifications if phone stays idle for a bit but its no problem as the first thing I do is to check WhatsApp when I get phone in hands.
Now on stats, screen is again at 1st position (as it should be I guess) with 35,66% power draining;
2nd is WhatsApp. (13,57%)
However there is still a bit of battery drain caused from something else. When I go to sleep I always turn phone off. This night it was at 43% of charge. When I turned it on it was still at 43%, but went down to 39% in less than 5 minutes even if not in use (used for, maybe 30 secs? Just checked WhatsApp).
I don't know what's going on.
idk why but this started happening on 11.0.3, before this it wasnt draining as much, but ya I noticed this very recently, it went up to 40% batt drain for me too, I reinstalled it and used the battery saving thing on it and my battery drain's fine now, I don't see WhatsApp in my battery usage menu, but sometimes I miss push notifications so that kinda sucks :/
hope WhatsApp and/or xiaomi fixes it, or if LOS or pixel experience gets stable enough I'll flash it, hope the battery drain's fine on those roms
I am also having huge battery drain in standby , around 2 -3 % per 1 hour.
Tried unistalling all social apps but the drain persists, also phone is not going to deep sleep. Now im trying PE rom and standby drain is down to around 1.6% per hour which is too much for this chipset (k20 pro in standby with same apps is around 0.5% per hour)
