Question about Android system drain!

So we have two apps in battery drain... First is a game Royal Revolt 2 that is a tower defense 3D game that run 42minutes (not in a row) and Android system that also run for 40minutes...so both of them drain about 10% of battery... How this is possible I mean the Android system drain the same amount of battery as a 3D game?

Do you still get the Android system drain if you don't play the game?

I get about 40minutes drain on 12Hours usage (not SOT) and according to GSAM biggets drainers on Android System is ActivityManager-Launch and ConnectivityService...but im not wondering about the drain of AndroidSystem only why it drains so much as a 3D game!

I had a similar problem but I seemed to have fixed it. I am currently on Omni Rom latest nightly, installed Franco Kernel, and installed Greenify to hibernate apps that cause wake locks and run in the background continuously. Since I have done these 2 things my battery life has been much much better. Before I would be lucky to make it 8-9 hours on a single charge. Now im averaging 14+ hours. Still not amazing but better. Give these two things a try.

Im with stock franco and greenify...i have at least all my apps that i dont need notifications greenfied....but i still dont get why android system drain as much as a 3D game!

I have the same problem. This question will never ever be answered clearly.
Aaand..location reporting off.

10% drain on android system is not high at all, its very normal.

I have been using My phone all day so far mainly to listen to music
Android System is only 7%
Compared to the other apps I have been using all day I don't think 7% is bad so 10% may be normal. However this is over a 7 hour period.

Yeah simms but why it have the same drain as a 3D game??games need more resources..CPU and GPU I/O etc....android system are just some OS features...

Many things can make Android System drain go up, it's not just one process. I believe Widgets battery drain shows up here as well. How many widgets are being used and how often are they updating?

hmmm....maybe your right...if we add all the features that drain with android system and think that revolt isn't such a heavy game it make sense that they drain the same for a specific time...

Battery life is is bad now. 4+ hour wake time.

So I had great battery life not too long ago but now I can barely make it a whole day. My awake times are very high and I can't pinpoint the cause. I attached some wakelock detector info. Right now I have about an hour and a half of screen on and 16% battery left.

I am having same issue with phone getting really warm. No new app installs other than things like wakelock detector. I can't figure out what is causing it and better battery stats isn't showing me anything.

Add me to the list. Never needed my third battery until yesterday. No out of the ordinary modifications.

Try freezing maps and other not needed Gapps, it solved my long wake times. I also use Tasker to hibernate all my apps then put the phone in airplane mode when the screen turns off then waken them up and turn wifi back on when the screen comes on, battery life through the roof

So what's a normal awake time?
I've had battery problems in the past with other phones but usually wake lock detector can find the offending app. Nothing is jumping out at me this time. Google seems to be using a lot but I would like to keep using those apps unaffected.

Same here I took my phone off the charger at 10pm by 1am I was down to 37% with 17 min of sot, something isn't right, I'll try to grab ss tonight. And yes the phone gets really hot

I just had my G3 replaced after my new one suddenly died on me.
I notice a couple of subtle software changes by AT&T.
Yesterday my battery was on 60%. Before I left the office.
When I got home (45 minutes) I took the phone out of the pouch and it was really hot and the battery wad won to 19%.
First time this has happened to me. Will have to monitor.

I got fed up with it all. I did a factory reset. I'm going slowly re add apps back. I certainly noticed a performance bump after the factory reset. Night and day. I didn't even realize how much it slowed until i reset it.

wake lock detector isn't really a good app for telling you exactly what the issue is. betterbatterystats is your best bet to find out exactly what the issue is - it will tell you precisely what the issue is holding your phone awake.
Sometimes, shutting down and pulling the battery out for a second is all it takes to fix the problem. rebooting doesn't always solve whatever it is...

My phone "freezes" now and again, it always has something to do with me texting, but screen off and on will fix it..and it does get warm when frozen per say...but it will normally fix itself with me interacting with it. But if your guys are not holding it when it happens I can see it draining out your battery stuck at higher clock for no reason...now wonder if I should pull logs....
When I say interact I mean I have to push the power button. Knock on won't work. Similar to the dreaded sleep of death but seems to pull out of it.

Like another user mentioned pulling battery or at least resetting the phone periodically helps with battery and helps keep things running smooth. Using Better Battery Stats and looking at Alarms and Partial Wakelocks is a good way to determine if there is a rogue app killing your battery. A couple good Xposed Modules, if you're not using them or aware of them, are Greenify to help hibernate apps that like to constantly wake the phone and NLB Unbounce module is a good one for if you want to keep your location on and keep Google Now functionality. You can set how often you want the wakelocks and alarms to trigger and with the donate you can do the same with any wakelock/alarm. Just be cautious if using the pro version as some alarms or wakelocks if disabled or tinkered with incorrectly could make the phone unstable. Just a few tips/ideas. I have the VS985 and have had pretty good battery life since getting everything set up and debloated. Usually about 17-18 hours on battery (I don't sleep much) and 4-5 hours screen on time. I like the screen on the brighter side as well, which usually I adjust with the status bar so I don't have an exact percentage for the brightness. For some other tips and apps or even maybe something you haven't thought about check out this thread: G3 Battery Tweaks :good:

Factory reset.

I noticed my phone was getting warm in the pocket too, with bad battery life. I finally figured out the phone was waking as if it thought it was getting the 'double tap' to wake. I believe you can disable the double tap in the secret menu (3845#*850#)

Help finding/fixing idle battery drain

Hi my wife bought a Note 5 two days ago (9/30). She did all setup, app restoring, etc that evening and fully charged the phone overnight. However her phone is experiencing idle drain that I need some help fixing.
Some other info: battery saver modes are off, wifi is always on (but only connected at home), bluetooth is always off.
10/1: Arrived at work with 100% battery
A little over 4 hours later, with light use, the phone was at 51% with less that 45 mins SOT

With facebook as the biggest offender I suggested she turn off the setting of pre-loading pics and videos.
When she got home she charged phone to 100%. I also changed mobile network to CDMA/LTE. Here's how the battery looked with light use before going to bed:
10/2 - Left the phone unplugged over night to see what would happen, it lost 12% sitting on the nightstand for 8 hours.
Will report back later this afternoon to see how the day is progressing.

First step for me in reducing battery drain was to disable the Facebook app. It is a battery hog and was always at the top of my list. Instead, use a browser and create a shortcut to facebook.com or install Metal from the Play Store which is a web wrapper for Facebook and so much lighter. Sometimes I still get strange battery drain from Android system (up to 35% sometimes!). But this usually gets resolved just by opening up recent apps and closing all.

Hmm, I don't have problems with Facebook app on my droid turbo

Some people want notifications.

Regardless, Facebook doesn't seem to be showing up at the top afte the setting change. I'm interested to see what she has this afternoon. Will have some updates screen shots later on. I also asked her to charge ~3pm then drive home with nav on to see what the battery looks like under heavy usage.
I need to dig into Android System to see what's going on there, any ideas? Will GSAM pro give more insight here?

Not looking good, 22% used in 2.5 hours with 20min SOT

Where is the setting for turning off preload pics and videos in Facebook? I dont see it in the facebook app settings.

I lied, facebook setting is "play videos automatically", I have to assume turning this off will save data/battery. Also Instagram has "use less data" setting. I thought I read that this stops pre-loading of videos/images, but I might have imagined that?
Anyway, for facebook setting hit the menu button next to the notifications icon then scroll to "App Settings" near the bottom of the screen.

After most of a work day and light use she's down to 58%. Looks like facebook is back up there, odd because it's not a problem on my phone.
Does anyone know how to troubleshoot why Android System is using so much battery?

I have a note 4 and I'm having similar issue ls

Hi I'm facing kind of same problem but other device HTC one m7 and rom is aicp I don't know what is draining battery in idle time but almost 10 to 20 % is gone in idle and the fun thing is I use airplane mod all the time

You guys have to also take in consideration the Lollipop total connection time bug. Apps open up a connection and it won't close it when it's done... For example my first charge cycle I signed into instagram and it used 40% of my battery without me ever open again. The total connection time of most apps ends up being hours when it shouldn't be. That won't be fixed untill Marshmallow comes to the Note 5. Google is aware and has fixed it. It's on multiple Lollipop devices.

If the device is rooted then you can try Greenify to hibernate the apps which are consuming the battery life.Try other simple solutions like disabling the Wifi and other tools when not using them.Sometimes Play services may cause the issue so try to fix them.There are some guides which may help you http://fixdroidbattery.net/fix-fast-battery-drain-problem-on-samsung-galaxy-note-5/
http://recomhub.com/blog/how-to-fix-samsung-galaxy-note-5-fast-battery-drain-problem/
Hope these guides will help you

The problem is ...because of the device used to be root although we flash original stock firmware it is still drain when device idle ...you can take a look in Android OS and see stay awake period ...one way is flash custom room that said deep sleep fix . Hope this comment could deal your problem

Marshmallow 6. 0 wifi battery drain bug, it's not actually draining

So I am back to the stock rom and recovery and the wifi drain bug is back. :'(
Though I noticed the CPU's runtime stays roughly the same at 22 seconds, the computed power use is 536 mah but there is no actual showing of power use and my screen on time in my lowest brightness + adaptive brightness setup is Still giving me a good near 10 hours SoT of constant use.
This means that the wifi battery drain bug is. Not actual drain, but it's just a bug that shows it like that. Notice how nobody actually has reduced battery life because of this? Those percentages the bug shows are a lot but nobody has less SoT because of it.

Same here. Android System keeps my phone awaken all the time, even if screen is off.

I never noticed this bug. Do you mean when you wifi is switched off its still showing like it was on all the time in the battery stats?
The only bug I noticed is the mobile signal drain when using dual sim roms on my single sim device.

Since it's not draining your battery I shouldn't worry to much.You could try clean dalvik and cache and if that doesn't help try a factory reset or reflash the whole rom.

I still have no problems with wifi draining though, I mean, look at the time it was actually on, if it was seconds, it really isn't draining, computed power use isn't actually what it drained.
I even went back to stock, updated all the way to 6.0.1, 2 days ago, same reporting bug is back but no actual drain.

Disable location scanning, and search for Wi-Fi on the background. After reset and the Wi-Fi status on the graph should stop. At least this is what I do, after using the maps or tinder, or other location app

I fixed the battery drain due to wifi
Go to settings, backup and restore
Reset the network settings, reboot the device and charge it to 100%
No more wifi eating battery

Something is messing my battery up.

While using Twitter or any app, my battery goes down at least 4-5%. I can't get decent battery on this.

post your android systems battery stats

is your phone band new ? if yes maybe you need to let the battery make some charging circles

It is pretty new. I didn't think that would effect anything. I guess I will let it have some cycles then.

I have some ideas that might be able to get the problem solved. I would first try turning off your phone for 5-10 minutes since it might be overheating. Then I would uninstall any new apps that you might have installed since you can remember the battery drain starting. There is a small chance you might be experiencing some battery drain issues from a third party app that caused a virus. Its also a good idea to get a security app like avg since its free. Other then that you might also want to check that your phone is not completely full on storage, and also consider turning off the facebook app since it can cause some serious battery drain issues as well. I think thats pretty much it if you want to get rid of facebook on your galaxy s7 here is how to do it. and it will really help with your battery life

So I used it up for a day and let it die completely. Charged it right back up and now its pretty bad today. These are screenshots from when I made it die.
I did disable Facebook. The Android System and Screen are using the most up right now. It went down about 7% for being almost idle. I used Twitter once.

Possible Solution to the DRAIN!
Ok, so I've had the same issues as you. My findings are as per Gsam Battery Monitor:
1. High Android OS and Android System usage~ 20-30%
2. High Phone Radio ~ 40% at times
3. Overnight drain of at least 4% (stanbby drain)
4. Screen usage 'while off' higher than 'while on'
This was frustrating and is as mentioned by other users to be a bug from updates and related to charging.
SOLUTION:
Today Gsam reports my Android OS and Android System usage and Phone Radio at 10% and below.
All i did was...
1. Let it drain to about 90% after charge.
2. Restart the phone.
3. Then plug in the micro USB to USB connector (the one that comes with the phone) with a flash drive attached and play a song/short video.
4. Unplug and enjoy great battery life.
This worked for me so it's worth a try. Will test a full charge soon and hopefully it doesn't require the steps above every time to stop the drain.
btw I'm NOT rooted, using LTE.........wifi,bluetooth, AOD and locations all off.
