Wifi draining battery??

I've only had my nexus for a week now and I'm trying to hunt down the reason I'm getting poor battery life. At first it was nlp wakelocks but that went away on its own somehow. Now its my wifi draining battery, in 8 hours of idle overnight it went from 100% to 79% and wifi was the top usage. I've never seen this before on any phone with any rom so I'm not sure what to do about it.

Hi,
Try Settings/Wi-Fi/Menu/Advanced/ and untick Scanning always available...

This is what I did to improve my battery:
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email. Another thing I noticed was that some widgets are just more battery intensive than others. For example I found HD widgets consumed nearly twice as much battery as Chronus on the home screen but both displayed the same information.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.

Wifi battery usage

Hi, dumb question here and I know the answer is mostly dependent on several factors but I'm hoping for a simple answer. My phone goes through 2% battery overnight (8 hours) with everything turned off including Wi-Fi, Turning on Wi-Fi the phone goes through 2% per hour. I'm fairly certain this in not normal. I have had this problem since I install the ICS update back in 2012. Resetting the phone, installing new roms and disabling any and all features/settings have no effect. I discovered in Network Log that the kernel is using the network all the time. I tried blocking the kernel in Droidwall and AFWall+ but the kernel still has access to net. Below is a list of things I have tried which had no effect. I thought maybe flashing a kernel but since Slimkat, which I'm using now, has a custom kernel I doubt if that would fix the issue? If 2% per hour is normal then please let me know or please help me fix the issue if possible,
Fom the beginning
Put in new battery in case the old one is bad
Erased all files on internal storage

Using Slimkats simple and dark background
Display Timeout set to 1 minute
Display set to Low brightness (about 10% to 25%)
Only installed 5 apps: Wakelock Detector, Better Battery Stats, AFDroid+, Network Log, Greenify
I have since installed my all my apps believing this can’t be fixed or it’s normal but it was not like this when I got the phone and it had GB on it.

Simple answer, 2% over night is very good. You're not going to be able to do any better than that.

You misread the post. 2% overnight when wifi is off. 2% per hour when wifi is on. so I lose 16% overnight with the wifi on.
But it looks like I may have fixed of at the very least improved the situation. As I said I have already installed all my apps. I have 3 running in the background (sound profile, Halo, and Greenify). I also change some of the settings back as well (enabled sync, extra Slimkat graphics, Slimpie, Heads up, OK Google and a couple others.) I then flashed the Wild Kernel and installed the companion app, Tame. I set the CPU to Intellidemand/SIO. For the last 4 hours I haven't touched the phone and only 3% battery has been used. That's a much better battery drain then before. For overnight that would be 6% vs 16%. But from what I read that's still to much since the only difference is the wifi being on. I can live with it though. I did notice the kernel is still hitting the internet a lot for some reason. I can live with this though.

[Fixed] Standby battery drain

Hello everyone!
So this thread is for those guys that are still having the standby drain even after trying everything and got no help.
My Device Is not Rooted​Since last 2 weeks my device was having super standby drain and I couldn't help that.
First I thought that it was due to the battery wearing out. But I had this phone(exynos version) for around eight months and that is not enough time for the battery to drain out fast. So I started looking for the fixes in the xda threads but none of them had a mass effect on what i was suffering from.
Then I read about that app named the "Better Battery Stats".
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
I used this app to monitor the usage that was being done by different apps.
Most of the battery i.e 61% was being consumed by the apps that were running in the background. And the second big consumer was the android system. So as was mentioned in most of the posts what I tried.
1) Settings> Display> Resolution> Fhd to hd
2)Settings> Device Maintenance> Battery> Save Power and All apps put into always sleeping apps.
3)Setting> Connections> Location> Google Locaation History and disabled it.
4)AOD Disabled.
5)Sync Disabled.
6)Wifi> Advenced> Keep wifi turned on while sleep and set it to never.
7) Reset> Reset network settings
8) Boot into recovery and wipe cache patition
9) Reset factory data(Wipe everything).
And after doing all these steps nothing much changed my battery life since when i after resetting my phone again updated all apps from play store and resetting battery got an SOT of around 3 hours.
Then I again started searching for the problem.
I installed the accuBattery app from play store.
https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en
And saw that phone was not entering deep sleep for hours that was causing the standby drain!
The major reasons for the drain were.
1) TOUCHWIZ HOME!
2) Google Chrome.
3) Facebook app.
To fix that I applied Lawnchair as my default launcher.
set the theme to dark. Disabled the location permission in the facebook app. And disabled google chrome.
Other settings that also helped were
Change the resolution to hd. Disable google location history.
And boom.... It worked Like a Charm....
Now to add an extra something to the battery life i switch to MID Power Saving mode. That Also helps alot when phone is not being used as it stops background data usage by apps.
Now the average sot that i get from my phone is around 6 to 7 hours.
And the phone sleeps like a baby. 5% Drain in 10h and wifi was on for the whole night. Deep sleep for 9h 41m.
PS: I use most of the time my phone for gaming and heavy usage.
Hope this will work for you guys too.
Screenshots Are attached for the proof!!

Thanks for this man

How are your notifications? I'm having a lot of trouble with delayed notifications, emails/messenger/etc just wake up when I take the phone and I don't even have to wait more than 5-10mins for what seems to be doze to kill everything.
I get whatsapp calls that I miss because the phone never receives it.
And STILL my battery life is far from great.. borderline bad I'd say. So sad

In settings go to device maintenance and hit battery you'll see an option for "always sleeping apps" enter any apps you don't want to run in the bsckground, which will probably be most of them. Saves a lot of data and a lot of battery.

Tips to For Increasing Battery Life on the Galaxy S9

Sooner or later you will find yourself looking to save some battery life. here are a few ways.
1- Disable Always-On Display
2- Put apps to sleep
3- Lower screen resolution
4- Use Dark wallpaper/ Shorten screen timeout
5- Auto Screen brightness off
6- Turn Wifi off when not in use.
The video shows how to do these if you're not familiar with the settings on the phone. Feel free to add to the list.

Honestly I don't get any better battery life when using the phone at FHD rather than QHD. If anything it seems to me that the software had become so optimized for QHD that it may actually turn out more SOT and general battery life times. But that may just be my experience, not sure

Every year someone makes this joke.

Here's a link to one of my recent posts of all the things that I disable. They all add up...
Also, never let the phone fall below 10% if you're able to control it.

Why not let it fall below 10% ?

I've yet to see any conclusive evidence that the battery life improves when you lower the resolution. Best argument I've seen for doing this is an improvement in scrolling and animations

And every year I laugh at it because every year people buy the best phone on the market and then make a list of how to disable everything and cripple it so they can squeeze another hour of battery life in.
I get it because I used to be obsessed with battery life but then I realized I have chargers, wired and wireless, everywhere.

Install BK Package Manager and disable all bloatware.

Quick tip for excellent battery life:
1. Go to wifi advanced settings and tell your phone to turn off wifi during sleep unless the phone is charging. ( helps a little)
2. Turn on data saver on your phone (so when ur phone is off it updates using ur data instead of wifi. since wifi is off during sleep if u did step 1)
3. Go into data saver settings and give unlimited data access to specific apps that you use such as Google play services( for account and data backup) messenger, gmail and any other important apps)
4. Go Into your battery settings, under unmonitored apps, remove every app sitting in there. Then go into always sleeping apps, and set everything to sleep except the apps you use the most and want to receive regular notifications for. (So of course Google play services and Samsung services if u use those to back up your data and some messaging apps and mail apps, messenger, snapchat etc)
If you do these steps you are preventing your phone from randomly syncing information. (The biggest culprits being the apps you don't really use such as the Samsung apps like AR EMOJIS, ant services, galaxy app store, etc).
this has saved me significant battery life. Averaging about 8hrs screen on time and get abt 2 days battery with relatively heavy use. (Inbox,YouTube, instagram, snapchat, bleacher report etc).
Hope this helps

Make sure you turn off your Bluetooth before you do that.

This is all I really do. Disable those apps and services that I don't use. I agree it's crazy to get a flagship phone to then just turn off a bunch of features that make it a flagship.

Any advise for standby drain? Thats where i seem to be suffering! Even greenify doesn’t help!?

Are you inside a building during most of the standby time? Or anywhere that would cause a weak signal? I found inside large building or places where cell reception is low causes a lot of battery drain during standby

No just no. Feels like i disabled every app there is. 4 hours sot. Maximum 24 hours total time. Draining 10% minimum during sleep if left unplugged for (7 hours) i put every app in sleep. Cant find samsung ar etc in (always sleeping apps tho) i set everything except for messenger. Snap.waze. bbs and spotify in always sleep. Still not sure it will work. Aod on. Auto brightness on.. maybe i shouldn't complain. But when people get 7 hours sot i feel like i need to complain. I had bad battery time with my s7 aswell.

I understand why you would be skeptical. i will try to get a screenshot the next time i have a chance.
Another thing I did notice is screen brightness is one of the biggest battery killers on the phone. Maybe try power saving mode but only use the -10% brightness option that should help a little bit or manage your brightness manually. Hope that helps

I'm pretty disappointed with the battery life on my S9+ to be honest. Today for example, with minimal usage, after unplugging at about 9:30 am I was down to 35% by noon.
I've recharged it and now left it sitting - it is consuming power at a rate of 1% per 10 minutes, just sitting on the table without me using it. I'm at home, with a strong 4G signal, WiFi router is in the same room, and Bluetooth is disabled.
I moved from an LG G6 to this phone because I was tired of the LG hanging and stumbling to do basic things, but at least the battery lasted a little longer - I could sit it on the table and I'd only lose a couple of percent over the course of a few hours.

WITH 52% battery left
Before I removed facebook it was about 30 hours or so.

[Fixed] Battery issues with 5.1.9

I've got the OP6 since release and haven't had any battery issues until i upgraded to 5.1.9. prior to 5.1.9 I used to get a 1-3% drop overnight. Post 5.1.9 I get about 1-2% per hour of stand-by. The drain is not so high like I have a misbehaving app, my phone sleeps ok with the occasional wake-ups to get notifications. I was just very happy with the SOT and stand-by times i was getting before i upgraded to 5.1.9 and just trying to get back to it.
Also it seems like i'm getting a little bit higher drain from google play services that before, it always shows up third on my battery stats list and before the update it used to be beyond the 8-10th place.
-Already cleared cache from recovery before this battery cycle (Beginning of previous cycle).
-Already cleared google play services Data before the start of this cycle (Beginning of previous cycle).
-Already cleared google app Data before the start of this cycle (Beginning of previous cycle).
-Already cleared app cache before the start of this cycle (Beginning of previous cycle).
-Scanning off, GPS battery saving, overnight data was on 4G not Wifi, advanced (aggressive) optimization on, all apps are being battery optimized.
I've read most related threads and haven't found anything that helped, What should I do?
Also I read on a thread that turning off Android system background process helps, is it safe to do that?
Update:
So I think I found a fix somehow.
-Clear data for all Google play stuff (service, store, games, Google app). Then restart.
- reset network settings.
- Also I traveled to another country and not using dual SIM as I was and only on one SIM now with LTE.
- stopped using maildroid and used Gmail for work email. It's the app I suspected to mess with my standby drain.
- Also I have found an anomaly with Google photos. There are three settings to back-up Google photos and all three do not talk to each other:
1- Within the app itself. Google photos> settings> backup & sync
2- Phone options> Google> Google photos backup
This one doesn't appear all the time, sometimes it's there and sometimes it's not! Haven't figured out why it sometimes show and sometimes not though, but last time it showed I made sure it's off)
3- Accounts> Google > Google photos backup
(Screenshots below)
All the above three options don't talk to each other at all. so if you have it turned off within the app and the Google settings menu it can still be on within the accounts menu.
I think that causes sync issues which leads to battery drain specially in standby.
My current setup that do not drain battery is as follows:
1- Google photos> settings> backup & sync (ON)
2- Phone options> Google> Google photos backup (OFF)
3- Accounts> Google > Google photos backup (OFF)
I get my photos synced on wifi without issues and no extra battery drain.
When I found out thy don't talk to each other and turned them all on (specially the one in the Google settings menu) I started getting extra battery drain and Google play services showed up persistently in my top three battery usage items. Screenshots in comments.
Standby drain is now back at 2-3% overnight.

Heres some of the things I do to maximize battery,
Every one is different though,but these work for me
Use dark theme always
Don't use aggressive doze
Don't optimize apps that you really need notifications from
Turn off Bluetooth,location
Use nova launcher with dark theme
Low to medium brightness,no auto brightness
Clear cache from cached data in storage regularly
Occasionally do deep clear from advanced
Don't use face unlock
Turn off unused gestures,
Just some tips,but I do get small battery drain at night anyway, I don't think you should worry about it

Just a recommendation I got before from users on OnePlus forums, the concensous generally there is to just use normal optimization.It does seem to drain less

I've been using advanced optimization since I got the phone and was getting very good results up until my aforementioned problem. Will give it a shot.

settings/wifi/wifi preferences/advance
check for keepwifi on during sleep...put never
check network notification...switch off
i hope this works

Nothing to do man, bull**** to use more 'optimization' by turning wifi off, using theme and other things. I mean we should use the phone how we want right?
Just wait for a new update...
All OP6 users got standby draining. Annoying asf.

Just a note, clearing cache in recovery does nothing. This phone doesn't have a cache partition.

Try restoring network settings.
*Settings, backup and reset, network settings reset*
This helped me when I was on Samsung s7-e when I had some strange drains from an update.
I have no issues with my device on 5.1.9

You are right 100%..this is obviusly semi product..i fight with their support team, already change with them more than 30 mails, they just ask screen shoots for this ss for that...they should give money back, in my hand phone go crazy just like that loose overnight 36% with everiting off. Sometimes during day too. I have this problems since i get OP6, 4 weeks ago.

I was using the same settings since I bought OnePlus (OOS 5.1.3) and I had an amazing battery life on OOS 5.1.5, but since 5.1.8 also 5.1.9, battery life sux. It is a problem with the software. In their opinion I should turn off all the features, even take out the sim card, maybe I should turn off the phone to save battery...

Feels bad man. The Chinese Oxygen version did fix the battery drain issue on 5.1.10. So we can expect it to.
Or you downgrade to before 5.1.8 and update when 5.1.10 is out.
Or you just wait. Don't do these 'battery optimization'. Not needed when the OS is the problem. And not your personal usage.

So I think I found a fix somehow.
-Clear data for all Google play stuff (service, store, games, Google app). Then restart.
- reset network settings.
- Also I traveled to another country and not using dual SIM as I was and only on one SIM now with LTE.
- stopped using maildroid and used Gmail for work email. It's the app I suspected to mess with my standby drain.
- also I noticed an anomaly with Google photos
Standby drain 3% overnight with 6-7 hours sot depending on usage. (Screenshot below).
now after I got good results Im using maildroid for this cycle to see if it had any effect or not.

Also I have found an anomaly with Google photos. There are three settings to back-up Google photos and all three do not talk to each other:
1- Within the app itself. Google photos> settings> backup & sync
2- Phone options> Google> Google photos backup
This one doesn't appear all the time, sometimes it's there and sometimes it's not! Haven't figured out why it sometimes show and sometimes not though, but last time it showed I made sure it's off)
3- Accounts> Google > Google photos backup

All the above three options don't talk to each other at all. so if you have it turned off within the app and the Google settings menu it can still be on within the accounts menu.
I think that causes sync issues which leads to battery drain specially in standby.

Weird thing is that I do not have the backup options under the phone settings under google or under account.
The only place it shows to backup photos is within the google photos app itself
