[Q] Android OS accounting for a huge part of battery usage

Hello all.
First off, bear with me if this has been discussed before, I have searched on google and in previous threads here (including the amazing 58.5 hr standby and 6 hr. usage thread) but I cannot find the culprit of the huge Android OS drain.
The battery lasts about 4.5 hrs of screen on time , which is pretty neat but nowhere near what other people are reporting. I know the battery needs to go through a few cycles before reaching its full potential, but the Android OS drain is what bothers me. Please note that I am unrooted due to warranty issues and an unreliable rootchecker.
I have done the following:
Disabled bloatware
Disabled LG MIT (P.S Do you recommend me to change other settings from the hidden menu?)
Disabled auto sync and backup in the settings menu.
Disabled Google Location services from Google Settings, although I kept the location settings in the settings menu due to widget.
I installed Lux to prolong battery life and it only operates upon waking the device.
Installed BBS and Wakelock detector
BBS shows 154 partial wakelocks in just 3 hours of standby from WifiOffDelayIfNotUsed and NetworkLocationLocator 191 partial wakelocks.
Wakelock detector shows a fair amount of Facebook wakelocks (86 in 3 hours - could that be the culprit?) and Viber with 21 wakelocks. This makes me miss Greenify - damn!
To round this off, can anybody please give me advice on how to solve this drain? As previously mentioned I am not willing to root it just yet. Feel free to include perfomance boosting tips as well if you have any
Thanks in advance.

I don't know how to solve the problem, but I can tell you this regarding root: Flashing a KDZ file after doing a full factory reset makes the roottripper reset too, including a showing of UNROOTED in the download mode.

Awesome news! Makes me reconsider rooting my device. I would still want to know what I can do without rooting. Thanks a lot for the info ?

Use Better Battery Stats to see exactly what is causing wakelocks and GSam Battery Monitor to see what's using other things.
"A huge amount of battery" is meaningless without context. If it says "50%" but that's .5%/hr, it means NOTHING else was doing anything really.

Disable KnockON, then Android OS will shrink to a few percents in your statistics.
I have tested it out, KnockON is causing the most part of Android OS.
Via LG G2

Wifioffdelayifnotused can be caused by going in and out of service. Disable optimizing in Wi-Fi, disable disconnect on low signal, set sleep policy to never.

well. As stated in OP I am using BBS but I will try out Gsam battery.
You've got a point there, but I'm not seeing 24 hours of standby, which annoys me. A side note- if there was no' something' draining my battery wouldn't it show as "device is idle" rather than android os?

Thanks for the tip. I am well aware that knock on uses up some battery but I don't recall the people getting 6 hrs of usage and 50 hrs of standby disabling this feature. Anyway I wouldn't disable this feature even if it would give me am extra hour of usage (unless in dire need) ??
And to the last post (which I forgot to quote) WiFi is set enabled in standby and the other option is disabled. The only thing I have checked in the advanced WiFi settings is lower battery consumption when device is using WiFi. Thanks for clarifying though.
It seems like. Android os is a mystery ?

The cpu power consumption is the biggest problem~
I had read a Chinese thread that CPU quality is the major problem causing this huge battery drain. Qualcom classified 7 quality levels. Slow, nominal, fast, very fast, ultra fast,....from class 0 to 6.(higher is better). the higher class quality means that cpu can use lower voltage to reach higher frequencies. The difference between C 6 and 0 is about 0.15V,,, :crying:

There has been some improvement but the phone was awake for 42 minutes more than screen on time . I posted some screenshots.

I'd say leave wifi optimization, set sleep policy to any other than never, and turn off the feature that turns wifi off if the access point you're connect doesn't have internet access. Or try aosp

If you're connected to more Wi-Fi than cell signal, leaving this on will do nothing to increase battery usage, more so increase it. Counterintuitive, but it is what it is. This is Google software itself, not hardware. Learn before you post BS. The phone uses more battery searching and refreshing for 4G data signal than it ever will on Wi-Fi. Do what this guy says if you spend most the day in Wi-Fi, and watch those counts hit the roof. If your of Wi-Fi most the day, just turn it off until you are, all good. Why waste battery when unneeded.

[HOW TO] Solve battery drain issue of YU Yureka.

If your YU Yureka's battery last upto only few hrs. Try this :
First check Battery status (Settings->Battery)
If you find Mediaserver listed number one battery drainer with more than 50% battery uses, then there is issue with Media storage
Now go to Settings-> Apps ->All, select Media Storage & disable it. Clear data & reboot. Now enable it & reboot.
Check battery uses after some time Mediaserver will not be number 1 & may not be in the list also. Even if it is listed , it will not take much battery.

How to save battery life on your Android device: 20 Tips
Most smartphones have either a Lithium Ion battery or a Lithium Polymer battery. Both are Lithium Ion though, and as such, do not have a ''memory'' which means you don't have to fully charge or discharge them at the beginning, and partial charging is fine throughout their life. In fact, these types of batteries suffer from low voltage, so it's actually much better to charge them, even if only a little, whenever you have the chance rather than to fully charge and fully drain them.
1. Use a dark colored background
2. Make apps darker too
3. Get rid of auto-brightness
Don't use display auto-brightness. It may sound good, but auto-brightness is usually way brighter than you really need. It's much better to manually set a super low brightness level that is still comfortable, and then just bump it up when necessary. This is one of the main ways to improve your battery life as the screen is one of the biggest battery suckers.
4. Vibrate away!
Switch off vibrate. Unless you really need that added awareness, turn off vibration. It actually takes more power to vibrate your phone than it does to ring it. Turn off haptic feedback too. Sure it feels cool, but it doesn't really add anything to your experience, and it's another battery drainer.
5. Don't use a knockoff
Only use original batteries or respected third party manufacturer batteries. Saving a few bucks on a battery that might damage your beloved smartphone is a poor choice indeed, and may also deliver sub-standard battery performance.
6. Having a timeout is good
Set your display's screen timeout to as short a time as is practical for you. Just think, if your screen timeout is set to a minute, it'll use four times the amount of power to have it on, every time you switch your screen on, than if your timeout is set to 15 seconds. Studies report the average smartphone user turns their smartphone on 150 times a day, so anything you can do to limit that frequency (through self-control or other methods listed below) will help keep your battery running for longer.
7. Get your notifications to leave you alone at night
Set ''sleep times'' or ''blocking mode'' to switch off Wi-Fi and mobile data when you don't need them. If your phone is basically off limits at work, set your device to not ring, vibrate or connect to the internet while you're at work. Likewise, you can set your phone to airplane mode when you're asleep or use sleep or blocking modes to set up limits for what your phone does during certain times of the day, whether that's while you're asleep, at work or in a meeting. Get to know the specific settings your ROM offers. Not only will you have to fiddle with your phone less throughout the day (or night), but you'll be saving on battery life too.
8. Your phone doesn't have to be smart all the time
Turn off smart features like air gestures, smart scrolling and the like, Unless you really use these features every day, they're just using battery power for a feature you don't use.
9. Nor do you need to be connected 24/7
Turn off GPS, Bluetooth, NFC, Wi-Fi and mobile data whenever you don't need them. Turning off location data, or setting it to use Wi-Fi or 3G data rather than GPS works perfectly well. Only turn on Bluetooth and NFC as long as you need them, and there's no need to have both Wi-Fi and mobile data turned on at all times. If you use Wi-Fi a lot though, say at home and at work, then it makes sense to keep set your Wi-Fi to ''Always on during sleep'' as this uses less power than to have your Wi-Fi reconnecting every time you wake your phone.
10. Try out Dynamic Notifications
Use lock screen widgets or notifications if your ROM supports them, or install an app that does it for you like Dynamic Notifications. You'll be able to get basically all your content without having to unlock your phone fully and navigating around. You still need to light your screen up, but you'll have it on for much less time than normal. using a lock screen notification app with a black background can save your battery life significantly.
11. Don't get bogged down by widgets
Ditch widgets you don't really need, especially those that are connected to the internet like weather widgets.
12. Don't let your apps fall behind the times
Keep your apps updated. There's a reason developers constantly update apps, and many of these reasons are memory and battery optimizations. Keeping your apps updated also means you have the best optimizations available. Likewise, delete old apps you no longer use, as these may be running background processes that chew up RAM and battery life.
13. Use your battery saving mode, now!
If your phone has a battery or power saving mode or other battery management option, make use of it.
14. Explore the battery saving features on your phone
All ROMs, whether it's stock Android, OEM UI's like TouchWiz or custom ROMs like CyanogenMod, have various settings in the menu to help conserve or optimize battery consumption here and there. Find these various options for your device and ROM and make them work for you!
15. Choose when you sync your data
Turn off auto-syncing for Google accounts. If you don't need every single Google account updated every fifteen minutes, just go into your Settings and Google account and turn off auto-sync for those apps you don't need constantly updated.
16. Be the master of your app updates
Set apps to update only when you launch them. If you rarely (or very frequently) open an app, it might be better to only have it update when you do so, rather than updating automatically all the time via push notifications or sync intervals. If you only check email once a day, why not let the app update then only, and if you're on a widget or app every couple of hours anyway then why not have it update each time rather than every fifteen minutes when you're not even looking at it
17. Be app update savvy in the Google Play Store
Change your Google Play Store settings to manual update your apps. If you have the Play Store set to auto-update, you might have fifteen apps updating when you least expect it, destroying your battery life (and data plan) without you realizing it. If you use even half of these battery saving tips you'll see a marked improvement in your battery life.
18. Turn off Google hotwords
Stop your phone from always listening. Google's "Ok Google" voice searching is a fantastic and often very functional feature. The problem is that it can play havoc with your battery. Go into "Google settings" from your app drawer and tap the "voice" heading. On the next page, select '"Ok Google' detection". In this menu, the best option for battery life would be to untick all boxed, but if you are a fan of "Ok Google", tick only the "From Google Search app" box to ensure your device is only primed while in the Google app.
19. Get rid of animations
Disable animations. This process may differ slightly from device to device but the crux of it should remain the same. Go to your settings and to the "about phone" page. Tap on the "build number" around 7 times. You will be notified that you have become an "Android developer" (don't worry, enabling the Android developer options doesn't have any adverse affects, it just adds another option in your settings menu). Go back to your settings and tap on the newly inserted "developer options" menu at the bottom. On the next page, scroll down to where it says "window animation scale," "transition animation scale" and "animator duration scale", and switch all of these off. Your device's interface may no=longer look as pretty, but the battery life will be better.
20. Make your location services more battery-friendly too!
Turning off location services isn't just a fantastic way to save on your battery, it saves on your data plan too! Go into your settings and you will find "location" under the "personal" heading - tap on it. At the top of the next page it you will see "mode" in this menu you will be able to set the options for how your smartphone determines your location. Select "battery saving" on the following page.

The temporary solution for the YU Yureka heating problem is to switch the mode of phone from performance/balanced to battery saver mode. This reduces the continuous heating of the device
Hit thanx if helped.

Scheduled power on and off option yu yureka- any codes
there is no inbuilt scheduled power on and off option in yu yureka. It is possible to write code from developer options?

[Q] Battery drain and slow charging issue in Micromax Yureka

Hi android users,
I got a new micromax yureka and am having an issue of battery drainage from the very first day. I just installed few apps like whatsapp, facebook, mx player etc. Sometime later, I observed that my battery is discharging very soon. It seems like, can discharge from 100% to 0% in just 2-3 hours.
I checked the battery status and found that "Media Server" is listed on the top with 51%. For this, I did this:
Settings-> Apps ->All, select Media Storage & disable it. Clear data & reboot. Now enable it & reboot.
Referred from: http://forum.xda-developers.com/yureka/help/solve-battery-drain-issue-yu-yureka-t3015549
Now somewhat battery is discharging slowing but still results are not good. Also, mobile is charging very slowly. (Say <=20% in an hour). I googled other solutions for this problems, but none worked. Can anyone help me in this?
PS: My device is not rooted.

Yureka has released one update. Just checked if that resove this issue or not.
Also use auto brightness, this enhance battery life
You can also use Greenfy app to boost Yureka's battery life, but yureka should be rooted.

All ROMs, whether it's stock Android, OEM UI's like TouchWiz or custom ROMs like CyanogenMod, have various settings in the menu to help conserve or optimize battery consumption here and there. Find these various options for your device and ROM and make them work for you!
15. Choose when you sync your data
Turn off auto-syncing for Google accounts. If you don't need every single Google account updated every fifteen minutes, just go into your Settings and Google account and turn off auto-sync for those apps you don't need constantly updated.
16. Be the master of your app updates
Set apps to update only when you launch them. If you rarely (or very frequently) open an app, it might be better to only have it update when you do so, rather than updating automatically all the time via push notifications or sync intervals. If you only check email once a day, why not let the app update then only, and if you're on a widget or app every couple of hours anyway then why not have it update each time rather than every fifteen minutes when you're not even looking at it
17. Be app update savvy in the Google Play Store
Change your Google Play Store settings to manual update your apps. If you have the Play Store set to auto-update, you might have fifteen apps updating when you least expect it, destroying your battery life (and data plan) without you realizing it. If you use even half of these battery saving tips you'll see a marked improvement in your battery life.
18. Turn off Google hotwords
Stop your phone from always listening. Google's "Ok Google" voice searching is a fantastic and often very functional feature. The problem is that it can play havoc with your battery. Go into "Google settings" from your app drawer and tap the "voice" heading. On the next page, select '"Ok Google' detection". In this menu, the best option for battery life would be to untick all boxed, but if you are a fan of "Ok Google", tick only the "From Google Search app" box to ensure your device is only primed while in the Google app.
19. Get rid of animations
Disable animations. This process may differ slightly from device to device but the crux of it should remain the same. Go to your settings and to the "about phone" page. Tap on the "build number" around 7 times. You will be notified that you have become an "Android developer" (don't worry, enabling the Android developer options doesn't have any adverse affects, it just adds another option in your settings menu). Go back to your settings and tap on the newly inserted "developer options" menu at the bottom. On the next page, scroll down to where it says "window animation scale," "transition animation scale" and "animator duration scale", and switch all of these off. Your device's interface may no=longer look as pretty, but the battery life will be better.
20. Make your location services more battery-friendly too!
Turning off location services isn't just a fantastic way to save on your battery, it saves on your data plan too! Go into your settings and you will find "location" under the "personal" heading - tap on it. At the top of the next page it you will see "mode" in this menu you will be able to set the options for how your smartphone determines your location. Select "battery saving" on the following page.

Hi android users,
I got a new micromax yureka and am having an issue of battery drainage from the very first day. I just installed few apps like whatsapp, facebook, mx player etc. Sometime later, I observed that my battery is discharging very soon. It seems like, can discharge from 100% to 0% in just 2-3 hours.
I checked the battery status and found that "Media Server" is listed on the top with 51%. For this, I did this:
Settings-> Apps ->All, select Media Storage & disable it. Clear data & reboot. Now enable it & reboot.
Referred from: http://forum.xda-developers.com/yureka/help/solve-battery-drain-issue-yu-yureka-t3015549
Now somewhat battery is discharging slowing but still results are not good. Also, mobile is charging very slowly. (Say <=20% in an hour). I googled other solutions for this problems, but none worked. Can anyone help me in this?
PS: My device is not rooted.

Hello!
The perfect way is to root your device! (Note that rooting YU doesn't void Warranty) .
By Rooting, you can install many battery saving apps like Greenify which puts all the apps into Hibernation, which prevents them from running in background when not in use! And also, this is done automatically if your device is rooted!
If you install a custom Recovery like CWM or TWRP, you can flash custom Kernels, which give you the complete access to customize everything(literally) of your hardware and if you optimize the settings correctly, the battery life will be Awesome!!
Hope this Helped! :laugh: If it did, hit the Thanks:good: button! And hesitate not to ask anything regarding this!

[Q}Lollipop Yotaphone 2 battery life - any fixes?

Hi all,
Having just bought a Yotaphone 2, latest model 801 processor and with Lollipop installed, I was impressed with it... lovely screen, sharp response, great display on the back ....until I realised that battery life on the EPD or indeed doing nothing was (and is) terrible.
This somewhat negates the point of having the EPD. Because whether you use the EPD or not, as others have found, the processor seems to be spending 100% of the time doing something like trying to connect to Google headquarters to report my unethical swearwords as I look at the battery level heading south.
To try and make sure the phone was using the least power, I went through all the running apps and services and terminated as many as I could, turned off things like Yotafit tracking, turned off the service that sends all your contact details to the Kremlin, and so on... then, I turned on the Yotaenergy mode and despite that, we are at less than 24 hours with virtually no phone usage at all. Fully 50% of all the energy according to the battery stats is being used by Android System and Android OS processes when the system is in standby. And the historic battery screenshot shows that the processor is active 100% of the time., even though the phone has not been touched. (sorry, not attached, I'll post at some point, but its not very interesting)
So, does anyone have any clues about how this can be fixed? I have seen screenshots where people have shown that their processors are not active the whole time, and I imagine they have Lollipop? I have heard Lollipop has got some kind of bug which means that data connections are live the whole time, not sure if this is related.
(This might explain the sudden appearance of half price devices on eBay around six months after launch in the UK.)
Many thanks in advance!

YotaDevices has acknowledged the problems on Lollipop battery life, which is the reason they won't be shipping devices coming to USA preinstalled with Lollipop, but with KitKat. Now that I've played around with the EPD and created some widgets/applications for it, I can spot many places where things can go wrong in maintaining battery life and still keep things working.
Personally I've been lucky with the battery life on all versions of Android. When I updated to the last version of Lollipop (firmware 1.44), the phone did show poor battery life for hours after the installation was finished, before calming down to the promised 5 days stand by. Are you on the very last firmware? (Settings - about phone - build number)
As a last resort if your device won't settle down, I guess you could roll back to Kitkat, which had a very good battery life for pretty much everyone. You can install it with Yota's flasher tool: ftp://fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe
Just carefully select your own region and then the last version of KitKat (4.4.3) they offer. As you are rolling back from one major version to another, I would suggest flashing pretty much everything. You will lose your data.
Yota has said that they are working on bringing Lollipop 5.1 or 5.2 to Yotaphone 2. Let's hope that that works better.

Thanks that was very useful. The question is, will Yota do another build ... or build another device? I'm hoping the Y2 has a bit of life left in it yet and they do launch in the US - it can only help the development community!
I reset back to factory/Lollipop last night as it was eating battery so fast I could not believe it, and I am on the latest build 1.44EU (and was before). Since then.. it doesn't seem to be misbehaving so much, but it does seem to insist that the WIFI is on (when it is switched 'off' in the settings) by 'on' I mean the battery usage recorder... I wil take your advice and 'take it slow' for now, but may flash back to Kitkat if necessary. It is a bit tedious having to reinstall all your apps by hand but this seems to be the only way to ensure it is relatively clean.
The screengrabs below show the phone doing nothing at all in Yotaenergy mode - per first post.

I am quite confident that they will release updated Lollipop sooner or later. They don't have the resources to piss off all their customers just yet.
Your Wifi still does some scans on its own for Google's location service, even if it's not enabled. You can disable this feature in the advanced wifi settings. But that is not the cause of your battery problem. Basically your device is awake all the time, meaning something is holding a wake lock. And by something I mean one of Yota's EPD compoments, which are counted as part of "Android OS" and "Android System" - your biggest battery hogs. It could be one of the EPD widgets that is misbehaving, or it could be some specific combination of them, or just something out of your control.
You could try removing ALL the widgets from the rear screen from Yotahub, then restart the device, and then let it run for an hour with the screen off. Then check the detailed battery log if the device went to sleep or if it was awake. If it went to sleep, you can try adding widgets back one at a time, and then check again if the device sleeps. Basically all the widgets which update periodically hold a wake lock momentarily (time, battery, calendar, weather etc). Of course if the problem lies on Yota's EPD framework, then this wont help at all.

Agreed, I suspect the YotaFit app going bonkers despite my efforts to kill it.... or the Yotagram service, the thing is, looking at the Yota specific apps, you don't really need them, as you can flip the screen with the Yotamirror, and then use any Android app. Sure it would be nice to have notifications on the EPD, but my main focus for this phone is use in bright daylight, and long battery life, not to actually look at the thing 24x7 so I can respond to emails every 30 seconds.
At this point though I'm just trying to determine how bad the underlying hardware is. The GPS on this phone seems to a bit flaky, as does the basic reception of mobile signal. (And I'm not using a metal bumper.) So, I'm happy to flash back to KitKat 4.4.3 to try and give it the best chance..
So, any clues/links about the Yota flash tool? I've put the phone into USB debug mode, installed the flash tool on my windows 7 desktop, and installed ADB/Fastboot as well, but at this point I'm having a bit of an android driver problem, and ADB can't see the phone so that probably explains why the Flashtool says 'waiting for device' when I fire it up. I will go digging to fix that, but I assume that the Flashtool will do all the stuff like putting the phone into bootloader mode, unlock etc...

The widgets I'm running at the moment without any problems are Time, Mini Calendar, weather, battery, and communications (the small widget which shows phone calls, notifications and sms). And of course my own widget.
The best way to make sure there are no useless services running is to root the device and uninstall them completely, but that's another story.
For the flashtool to detect the device, you need to boot it into download mode manually. The easiest way is to turn off your device and plug the usb in while holding volume down -button. The screen will show "download" or something in very small white text. After that the flashtool should find the device. You probably don't have to flash the user partition (it asks for it separately), i.e. the simulated sdcard section which holds all your photos, documents and music.
Edit. And when you have kitkat installed, the first thing you might want to do is to disable automatic system updates. Otherwise it will nag you about the Lollipop update all the time.

I've been facing similar issues and am considering a downgrade when I have the time. I'm really disappointed in yota and won't be buying their next device.
I have found this thread useful, you may too.

thanks gents, oddly, the advice to let the phone 'calm down' seems to be working. I decided not to revert to KitKat (yet), as every day I use the phone the battery life seems to improve. Yesterday it was down to 40%, today 60% after about a days use. I'm thinking a week of running in will give it time to stabilize. I would love to root the phone but I want to use the Good app, and that doesn't run on rooted phones... (shame but I guess that's the flipside of working for a big corporate for you!)

Try putting the battery widget on your epd. If it shows 5 days remaining when you are above 85% and you don't use the phone, then the device works as advertised.
That Good app sounds like a real killjoy. There seems to exist some Xposed modules to disable the root check, but they seemed to be rather finicky to setup and very easy to mess up.

I was suffering from terrible battery life after the lollipop upgrade and the EPD battery widget was never showing much above 1d anymore. After much research and tinkering, it has now improved and I am seeing greater than 3d again. I think the culprits were maybe google fit tracking which I have now turned off and I also de-installed and re-installed the google play services updates which is a tip I saw in an android forum. I also over the last two days have received several yota widget updates which may have also helped. At least for now I am seeing a comfortable day's use again!

I experienced poor battery life out of blue again. I went through all the settings, cleared dalvik-cache and cache partition, tried disabling everything, but nothing helped. It only showed <1 day battery life at 100%.
But then I went to mess around in the developer settings, and when I set the animation scales from 1x to 0.25x and enabled "Force GPU rendering", the battery life returned instantly to 5 days.
Just thought I'd add this to the list of things to test out if someone's experiencing poor battery life. The forced GPU rendering might have some unexpected effects on some software rendering based games.

dont know if this will help but just seen some of the new features of android m "marshmallow" one of which is doze and there is a separate app available on play store for this. i have installed and it has helped battery life !!!

I was going through terrible battery life after Lollipop as well. Suffered, tinkered, tried various things. Eventually I just said screw it, backed everything up and factory reset it from recovery. Since then it seems like it's almost back to it's old self. Obviously having root and using some kernel control apps, greenify and some other things helps it but It will happily do at least a couple of days with little-normal usage. Still don't think it's as good as KitKat but it's not too far off. The EPD really does help spread battery out too.

I did the same thing but a 3 weeks on, the battery is as shocking as ever.
Today, on battery since 0730, now @ 1115 51% and 3hrs left!??
No obvious apps causing battery drain, just google services!

I have had the phone nearly a week, and these are similar figures I experience. What's the point of the epd if my battery dies by lunch!

I think it is something with Android 5.0 that is causing the drain issues. I can go anywhere from half a day to a week with good batteyr life and then it will randomly start draining again. Some background activity seems to hold a permanent wakelock and will not let go of it. I am unable to pinpoint what app is creating the wakelock with better battery stats or wakelock detector since there isn't access to kernel wakelocks in either of the apps for our phone. A restart always fixes things though, so I have a tasker script now that lets me know when idle battery drain exceeds a threshold for too long so I know to do a restart, it's not elegant, but my battery life is exponentially better and gives me enough battery life to make it through the day without a recharge and leave the eink screen on all night as a tv remote.

I got a new phone

In the end, I got a new phone after my Yotaphone decided to brick itself. Its a Zopo Speed 7, Octacore, dual SIM, nice screen, and does 4G very well in my part of the world. It is also around $200 at time of writing. Its a Chinese phone typical of the genre, Zopo seem to be moderately responsive to bugs compared with Yota... This Zopa phone is running 5.1 Android and I can tell you that Lollipop is not the problem...
That's after charging the phone and leaving it overnight, with the battery saver mode on... not too shabby. Of course it won't actually last 28 days, but this phone is nothing special and it is capable of running without all those services running that the Yota has.
The Yota spent its entire time when I had it trying to contact Moscow with that dodgy 'dictionary app'. What (honestly) is the point of the e-ink display if it doesn't save power...

If you are experiencing "always awake" and wifi always on despite your settings saying otherwise it may be worth going into your advanced wifi settings and changing "wifi frequency band" from "auto" to "2.4 GHz only. I remember reading this tip somewhere else for an Android 5.0 phone that was having battery issues similar to this. I made this change about 24 hours ago and have noticed a dramatic difference in battery drain when the screen is off. When I look at my battery stats I am no longer seeing a solid bar for both wifi and awake. Worth trying.
For what it's worth, I have had fairly light use today, some checking of emails and facebook, 40 mins or so of music via bluetooth (with screen off). Total screen on time of 35 mins. The phone has been off charge since 06:30 this morning. It is now 17:00 and is showing battery of 71% with an estimated 2d and 8h left. Better battery stats show deep sleep of 71% whereas previously it had shown awake at 100%. Far better than I had before.

Have you tried using the setting so Wifi is only on while screen is on? (Unless on charge...)

I think I found the issue, at least with my phone.
I was syncing with exchange, and there is a nasty bug with android 5.0 and exchange sync. The sync is taking forever and doesn´t sync everything. Calendar and contacts missing.
Then I removed the ActiveSync connection on my phone and set up the app Nine to sync instead.
After that I got much better battery. This may help for others as well. The phone is just hammering the exchange server all the time and this takes up a lot of power.

Excessive Battery Drain

Hello everyone, I am experiencing the worst battery life I could ever get from a phone, Any way to help it get better? I need to charge my phone 2-3 times daily!
Here are the screenshots of the usage.

Same here as well. I'm on the new Oreo that now has been pulled. Lots of errors, missing picture in picture, but biggest mistake is that all files are allowed to be installed without consent!. How to now go easy back to Nougat?

Are you also having the same problems?

Go to device maintenance click on battery. Click on MID choose customize option at the top before you apply. I just leave the limit cpu speed on. I get over an hour sot every 18% YouTube alot and music. Only thing is apps start to lag when you switch really fast. But it probably won't if you don't close it. I have a habit of closing all apps before I turn my phone off. Whatever govener Samsung is using always max out the cup when you click something which drains the crap out of the battery. I use to charge my phone every half of the day until I did this. Closing and disabling apps didn't help at the beginning. This was the most effective way for me to see a big difference. Btw using auto brightness at 45%

Install a data monitoring apps, maybe you have some apps working in the background and draining the battery at the same time.

having data on chows battery, phone is excessively pinging towers, if you are on WiFi disable data in settings, make sure your location is set to battery saving (if using GPS yr battery will suffer, plus one only needs GPS for navigation), there are a bunch of bloatware apps and processes that run continually so install a package disabler or use a debloater to remove the 'junk'.

This time I tried something new, I entered *#0228# code when the mobile was at 15%, turned on Airplane mode and let the phone charge till 100%
I also turned location off and thing started getting better

Havng data on 24/7 will hurt, even just 2g/3g as phone is pinging towers for 3G, if you are i wifi area switch of Data, that'll be worth 20%

After Oreo update, I'm having the best battery saving of all time.
0.8%/h on stand-by (using dual Sim cards). 6-7h SOT. On Nougat, it was 3%/h on stand-by and only 4-5h SOT.
I did 4 things to achieve it (without root):
1. I followed this guide:
https://forum.xda-developers.com/galaxy-s8/help/guide-hunting-wakelocks-battery-drain-t3697324
Note: "Service Disabler" functionality was removed due to Google Play policies. Fortunately, the developers provided the previous apk with this functionality at their website: https://kunkunsoft.wordpress.com/news_2/
2. Switched to 3G when 4G signal was weak (2-3 bars).
3. Used Brevent app (must use adb commands every reboot, unfortunately): https://play.google.com/store/apps/details?id=me.piebridge.brevent
4. Used Tasker to: disable WiFi when Screen-off (except when Spotify is playing); disable Auto-Sync when Screen-off and enable it every 20 minutes; put Location Services to Battery Saving when Screen-Off (except when Waze or GMaps is running) and High Precision when Screen-On.
AutoTools (Tasker plugin) will let you modify some of those adjustments even without root (must enable it once via adb commands).
BBS and GSam are great tools to find out what's draining your juice. For me, it was mainly wlan_wakelocks (due to bad WiFi configuration), nlp_wakelocks (apps and Google apps draining when High-Precision is on), and Auto-Sync. Sometimes it's harder to identify the culprit because many apps wakelocks are hidden in Kernel wakelocks, so the first step above helped me significantly reduce Kernel wakelocks.

Why is your WhatsApp icon blue and why is it using so much battery?

You have used your S8 continuously within 6-7hrs.. S8 does not have bigger battery plus the apps like facebook, other social media apps drain battery like hell... getting 3-4 hours of Screen on Time is quite OK not Bad...
try using other app for facebook.. like FRIENDLY.. it almost same as facebook and battery friendly also...

After Oreo update, I'm having the best battery saving of all time.
0.8%/h on stand-by (using dual Sim cards). 6-7h SOT. On Nougat, it was 3%/h on stand-by and only 4-5h SOT.
I did 4 things to achieve it (without root):
1. I followed this guide:
https://forum.xda-developers.com/galaxy-s8/help/guide-hunting-wakelocks-battery-drain-t3697324
Note: "Service Disabler" functionality was removed due to Google Play policies. Fortunately, the developers provided the previous apk with this functionality at their website: https://kunkunsoft.wordpress.com/news_2/
2. Switched to 3G when 4G signal was weak (2-3 bars).
3. Used Brevent app (must use adb commands every reboot, unfortunately): https://play.google.com/store/apps/details?id=me.piebridge.brevent

Thanks a million!
I only went about 40% through the steps and here is the difference. Plus mobile data was never off!
Cheers mate. ?

GBWhatsapp aka Whatsapp Plus.
I use it most of the time that's why it uses much battery.

That's interesting, I use it all the time as well and for me it never goes above 2% or 3%. Only thing is that I don't do calls.
See my other post here.
