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.

My battery life has been great with the current set-up, but in the past 3 hours something screwy happened. I basically went to a function and I turned off BT, Wi-Fi, Mobile Data and GPS. Only thing on was the cellular network and I swear I didn't use it for more than 5 minutes. The battery was at 98% before leaving, now in those 3 hours it came down to 50%. What the crap? The only thing I did was to play Super KO Boxing 2 before leaving for about 5 minutes(It still shows its battery usage as 20% but no option to force close, so I am presuming it isn't running). I did open Maps and HTC Locations(Sense 2.0) for 2 minutes but I closed it because I didn't need it anymore, I also disabled GPS right after that. Now after all of this(game and gps stuff) I had 98% battery. Yet 48% of my battery went into thin air just like that, my battery use is Display: ~40%, SKOB : ~20%, Voice calls: ~15%(About 3 minutes), Cell standby ~2%, Wi-Fi ~4-5% or something like that. These are from memory since I turned it off and kept it for charging.
Any ideas what screwed things up?
Edit: Just noticed you are already familiar with the battery %age lcations.
From what you describe, it sounds as though there were some apps running in the background, slowly om nom nom'ing your battery. I daresay there are a few apps on the Android Market and elsewhere that can tell you what services are running at any given time, so you could get one of those.
If you're after ensuring maximum battery life, however, your best bet is to shut down the Desire, then fire it up again. That way, you can be sure there are no background services to drain charge. Couple that with lowering the screen brightness and display idle timeout (not to mention upgrading to Android 2.2), you should be able to go at least a couple of days on standby.
Sounds like one of your apps is keeping your device awake. I'd suggest getting app monitor like SystemPanel and run the monitoring for a few hours to see which app is consuming the battery.
And get WatchDog. It will notify you if there's any app that use the CPU more than 20%. You can set the percentage yourself btw.
All right, I'll be formatting the phone and flashing the RCMixHD v8 ROM(Was using v7) and then see what happens. i can bet my life that it was either HTC Locations or Google Maps screwing things up.
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.
Sent from my GT-I9195 using Tapatalk 4 Beta
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.

Up to now I'm happy with my Z1C.
But in the last weeks the battery drain went up.
Before that I could get a day and a half to two days of use , I am a moderate user during the day.
Most of the time wifi is off, 4g is off but bluetooth is on, day and night.
Before I had bluetooth turned off when not in the car.
But because I bought a Smartband talk I switched bluetooth to on without turning it off again.
Up to last week the battery was draining faster because of the bluetooth use but it was still good enough for me.
The last weeks / months I downloaded a lot more music on the external card and switched USB use to MSC so I could use it in my car. I listened to music in the car when driving to and from my workplace (1 hour drive single way).
Because it was charging in the morning and in the evening I did not notice any abnormal behavior.
Before I started to use the phone as a mediaplayer in the car I could get 1.5 to 2 days.
When using it as a mediaplayer this did not change, probably because of the charging in the car
Now I switched from workplace and stopped listening to music in the car.
Now my phone lasts for 0.8 up to 1 day max.
When looking at the battery stats it seems to me the mediaserver was eating up a lot.
So I deleted all data from the phone and I did a reset to factory settings. I also removed 80% of the music on the external sd card.
But even then I get a battery drain from 30-35% in about 7 hours time during the night.
I'm running again with only necessary apps installled.
So for the time being no xposed modules, no smartband talk and only switching bluetooth on when using the phone in the car.
But the problem does not seem to be solved.
I have a weak signal at home (1 bar), I had a weak signal at my previous workplace (1 bar) and I have a weak signal at my current workplace (als 1 bar max).
I wonder what is eating the battery so fast?
Is it the weak signal?
Is it because I charged the battery too much (every morning and evening in the car)?
Is my battery dying?
Is it related to an app (multiple apps)?
I have this phone since april 2014.
I am on 14.4.A.0.108 / unlocked / rooted with the doomkernel v22.
So can anybody tell me what monitoring app to use and how to interprete the results from such an app?
I'm in stamina mode.
Estimated lifespan battery is at 2 days when an actual battery percentage of 42%.
I already have betterbatterystats but I do not know if this is the best app for monitoring.
Is there something else I have to look into?
Today I was trying to get my settings in the state I need them to be and when looking at power management / battery usage I can see the screen is the biggest battery user but that seems normal in the current situation.
What about deep sleep, how to monitor this?
How to identify apps being the biggest battery consumers?
What about the apps in manage notifications, there's a lot of them, will it help disabling some / a lot of them?
I really like to get back to charging the phone only once every 2 days.
Any help would really be appreciated.

Better Battery Stats is you friend, it will help you locate what it depleting your battery and keeping your phone awake, as well as listing the deepsleep times .
If you have a rooted phone download Disableservice from the playstore. Reading your post you use a fitness tracker so disabling all of these might not work, but it's worth a go.
Once it's installed, open the system tab, open Google Play Services, then untick (disable) the following:
ConfigFetchService
FitnessSyncAdapterService
GoogleLocationManagerService
GoogleLocationService
NetworkLocationService
ProximitySettingInjectorService
UserPresenceService
WearableControlService
WearableService
WearableSyncService
then reboot your phone.
Disabling these from running should have no impact on your phone, it doesn't for me, and will give you 10-15% more battery life.
Turning of sync on your Gmail also saves a lot of battery, especially if you live in a poor reception area, as it polls the Gmail server every few minutes. Likewise sync on your normal emails. It means you have to check yourself to see if you have any mail, but will put a few extra hours on your battery.
The other thing that extended my battery life was deleting the cached data. Settings\Storage and hold down on Cached data until you get a popup asking you to delete it. I know it sounds bizarre, but it really worked.
Try putting a stock kernel back in for a few days and see if that makes a difference.
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 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.
