Help re battery drainage and synapse optimisation

So I'm fairly new to the Android's scene, I've come from a jailbroken iPhone straight to the nexus 6 after doing a load of research on which phone I should get.
The iPhone is so much easier to work with, in it's jailbroken and default state. I've had my nexus for about 3 months now and only now feel alright using the words ROMs, kernals and flashing.
I want to optimise my nexus for maximum battery life, I know I'll have to comprise with animations and processing power etc.
Here are a few sc of how my set up is currently

I flashed my current ROM and kernal last night and did not charge over night so I could just see how much drainage there is when its on standby. This morning I charged it up to about 81% and used the phone normally and I've noticed my battery is actually depleting really quickly. Especially when you take into account I had my setting to power saver, and I was using pixel off battery saver and a kernal made for huge battery life.
I know the issue is with wakelock? But I can't find any help and what I can find is far too complicated to follow.
Also, synapse. That thing is a nightmare for a noob like me. If anyone could link me to a thread or website that explains each feature or somewhere where someone has shared their setting for getting the most battery life, I will be very grateful.
Thank you in advance

@icameforthehax Thank you for posting the perfect example of how to ask a question! You've provided all of the proper information, in order for someone who can help, to do so. I'm sorry I can't answer your specific questions but I had to comment on the quality of your post. Well done and welcome to Android! :victory:
I'm sure someone with more expert advice than I can provide you on this topic, will help you shortly. :good:
I will suggest this though, look into a third party battery stats/wakelock detector app to more specifically isolate any wakelocks or battery drain. Also, greenify is an excellent option for root access.

well, your play store and android os is way to high on battery percent used! screen should be the #1 battery drainer(or close). other things shouldnt be that far above the percent for screen use.

Yes, the fact that my screen wasn't the no.1 drainer is why I was concerned enough to start thus thread. Any recommendations as to which app(s) I should use?

android os i wont be too concerned about, since that changes depending on how you use the phone, but the play store.. were you restpring a bunch of apps or something? anyways, recharge your phone fully, then use it like you normally would, then past the battery results here, after a full use of the battery, and ill look at it again. next time past not only the main battery page, but if you press on the chart itll give you more info, paste that as well so we can see your signal, wifi, and if the phone is sleeping.

if you downloaded a bunch of apps, thay would explain why. anyways, the first 2 battery cycles after flashing a rom will be a little lower than normal. after, battery should be better.

again, you just flashed franco kernel, so youll have to give it a battery cycle or two to regulate, then you can start judging battery life. but your device is goung into deep sleep, so that's good. also, do you always keep wifi on? if you keep it on, but dont use it it'll drain battery. also, what do you have your brightness set to?

OK, thank you. The issue is me changing kernals and ROMs etc. I'll cycle my battery 2 time as you've said before I start to judge battery life ty.
Yes I keep WiFi on and use wifi. My brightness is dragged right down with adaptive off, I then change it to 50-70 if I'm outside.
Thank you very much for your help though

Synapse is confusing to anyone who doesn't know what they are messing with...try FauxClock or Trickster Mod...much simpler and you won't have to worry about changing things by accident by swiping to the next page as you would with Synapse.

Simms is absolutely correct - after a rom or kernel flash you need to give the phone a few days to build up its cache etc...only after that can you properly judge battery life and performance.

screen brightness is a MAJOR influence in battery life. i generally keep my brightness down below 15%. if i raise my brightness to 30-40%, then ill see 1 hour less screen on time. normally, ill see anywhere from 5-6.5h sot. another major influence is the quality of your phone/data signal. some people, no matter what they do, will never have good/great battery life, just because their signal quality is lousy.

Somewhat off topic, but Better Battery Stats is a great app for getting a much more in depth idea of battery life. It'll also give you all the wakelocks, which can be handy if you looking to do more in depth troubleshooting.

battery life results with galaxy tab s after lollipop update

So im pretty amazed with battery life on my T705 after lollipop update that sometimes i can believe my eyes i wanted to see if others getting the same worse or better . from last 3 tests ive done on standby it only uses 1% battery every 7hrs of standby , with wifi on all the time which is pretty amazing to me and with screen time i manage to get 7:20 hrs out of it with with still 20% battery left which again was amazing comparing it to almost 6hrs on kitkat share your experience after lollipop please

When things look too good to be true, they normally are not, Have you had any sudden shut-downs before the battery the battery is empty, if so the battery might need to be re-calibrated.

nop never had that issue but i have a friend whos suffering from that battery failure >< , why ?

I noticed this after the Lollipop OTA installation - spent a couple of days tracking it down... dunno whether it was the case with KitKat but anyway, it's a tip worth trying on any Samsung device -
If you have the Samsung "Toolbox" utility, that floats a button on the screen to access your choice of five apps from anywhere - turn it off. It causes the "security storage" process to peg at 20% all the time the screen is on if "Toolbox" is enabled. When "Toolbox" is disabled, "security storage" process drops to a couple of percent when the device is idle. There's quite a saving on battery drain.

My tab s 8.4 wifi on lollipop seems to drain battery a little faster than before. I managed 5 hours SOT with 18% battery left. Not sure how much better it was before under KitKat but I think battery was better for me under 4.4.2.

Toobox off. I didn't do a factory reset before and after applying Lollipop OTA so that might play a part in slightly faster battery drain. I always leave auto brightness on so that could also be the culprit for shorter battery life as the screen under Lollipop in auto mode is slightly brighter than how it was under KitKat.

Second and third cycle, you left the tablet plugged into the charger while using it?
There is no way you can have over 9 hours of screen on time and still be at 92%

Oh thanks for the clarification. Not sure how you were able to achieve so much SOT. Did you set it to really low brightness?

Brightness is set to auto at 5.... I use it to browse over Facebook app, tapatalk, movies, WiFi all the time on, even if there's no signal, comic reading..... Very multimedia use... No custom kernel, no deodex, no mods, no xposed.... Greenify, yes.... I think that's the key here....

So, if I am getting around 7+ sot and we are having battery issues.... When they fix it we will have around 12 hours sot?

I noticed my battery life definitely is better. I'd say by at least a hour. I'm also extremely debloated on the stock ROM so there's not much at all running. Like 6 programs on TW. Everything has always been very snappy for me, in Kit Kat as well. So I don't notice a speed difference but no bugs and better battery life so far for me. Im about a week in on 5.0.2

Great Battery life with everything enabled.

It's been a week since I turned on most features on my S6. Bluetooth all day. GPS enabled. Auto brightness. Apps syncing every hour including weather widget with location on. Ok Google on system wide and a lot more on too. I don't focus on SOT too much because I'm not on my phone constantly. I focus on overall battery life.

With only 3 hours screen on time of course overall battery life will be decent. I typically lose less than .25% an hour when my phone isn't touched. Slept 10 hours Saturday night and only lost 2%.

when you buy this phone you have to rooted and flash a kernel and a custom rom thats it!! for me im running vindicator r3 and xtretos lite and everything is work! is a huge difference from stock! for me this phone is perfect now. i multitask i do split screen everything you can do. i can't complain

I understand that. My point is that I have most features on all the time that people usually turn off just to save battery.

Everything you mentioned works fine without doing all that complicated rooting and ROM flashing process, then having to back up all your apps and messages and wait like 20 minutes to get it all back on there.

You could just buy an external battery pack case and never have to worry about battery life ever running out again within a 24 hour period.

I'm running stock rooted, I'm losing about 1% per hour while I'm sleeping. I'm hoping the battery is still settling in because I'm not able to get great SOT as of yet. I've had the phone less than a week, came from Verizon with the S6E. Would get about 4 hours SOT max there...
Sent from my SM-G920T using Tapatalk

My stock S6 will lose about 10-15% overnight when I'm sleeping, I usually end up turning on Battery Saver and enabling Airplane Mode and I still lose about 5-8%. I have to charge my phone a few times through out the day, I'm actually even happier with my JBL PowerUp speakers w/wireless charging, I have them at work and just set it on there when I'm at my desk so I can at least get more juice out of it.
I need to look in to flashing a custom ROM on this, I really don't care about tripping KNOX as Samsung Pay won't even be available for quite some time. Are there any other downsides to tripping KNOX? I know there are ways to get around it without tripping it, but I don't really know if I should care or not.

Turn off lte use only 3g-4g that will help with ur battery drain

Great battery life here with these tweaks:
1) I have a macro (Macrodroid app) which kills select background apps (excluding email, messaging, and such) when the screen goes off.
2) KTWeaker installed using the Asking Alexandra profile
3) Flyon Mods app is also installed and all tweaks are enabled
Under average use the phone can easily make it 24+ hours without a charge

battery life

Hi guys. I just bought my phone today installed all the apps and then fully charged it. However I am getting poor battery life. What is causing my battery to be crap? I don't see what the issue can be as it is a brand new phone. Coming from the sony xz premium i feel as if its a downgrade on the battery end of things. Does anyone have a suggestion

I thought my battery was terrible at first when I got it. I noticed lately I have not noticed so much anymore. Right now phone been on for 2 hours straight and lost 25% with brightness half way. Just give it time

It scares me that battery life is not going to be any good and I have to hunt for the charger through out the day. With my xz premium with about 4 hours usage i normally had 40 to 50% remaining. I don't want to think about charging my phone just to get through a day. Lets just wait and see if it gets any better

Android needs some time to adapt to your apps.
I bought my Note8 three days ago and don´t used it permanently respectively don´t have so many apps installed.
I charged it 2 days ago (at 18 o´clock it was fully charged!), now I have 48%
Before I bought my Note 8 I had a Mate 10 Pro with 4000 mAh and 60-70 apps. Android needed 3-4 days to adapt. In the first days I had to charge every day. After a week the Mate 10 Pro had to be charged only once in 2 days.
So do not worry!

Watching this with interest. Mine is a week old and I feel like I need to keep topping it up. On the road all day today and worried she won't make it!
I've a charger in the bag. But going to see how far I get!

Thats what i was saying while i have the chance i might return it and get the Pixel XL 2 or the mate 10 pro. I believe both have better battery life. The pixel loses out on screen quality but makes up with software and battery life. The mate 10 pro loses on software but kills it on battery life. So tough choice to make. However i can't stand poor battery life especially never having to worry about battery life on the sony xz premium

Had mine since day one and the battery gets better the longer you use it. I have several things disabled that are big battery suckers - Bixby for one, don't want or need it. I can go 1-2 to days of moderate use, using an ereader app but no game playing.

The better question is, what apps did you install? You need to just use your phone for a few days. It will begin to background/sleep apps you aren't using which will extend your battery life.

Like myself and others have said, just use the device. You're comparing a device you used for a period of time to a device you just got just over 24 hours ago.
Those apps are considered battery hogs because they don't sleep. Also, Xperia devices have a sleep function implemented. They were the first ones to ever have such a robust background sleep function of Android devices.
The sleep function should be on automatically during setup but it could be turned off. Look under battery settings and it'll be there with the option to turn it off. I recommend keeping it on.

Those apps are considered battery hogs because they don't sleep. Also, Xperia devices have a sleep function implemented. They were the first ones to ever have such a robust background sleep function of Android devices.
The sleep function should be on automatically during setup but it could be turned off. Look under battery settings and it'll be there with the option to turn it off. I recommend keeping it on.

Yes i will give it a week and see if it settles. If not by hy note 8 and hello next phone. Lets see what time will show

Not sure where the setting do turn sleep on and off is, but the phone has sleeped (is that a word?) a bunch of apps. Battery is looking good so far today.

There was a video showing ba they life from a s8 a s8÷ note 8 and the late. And the note 8 lasted 2nd best.

I've disabled knox, security folder, bixby, ant radio all the t-mobile apps, several of the edge screens and a few others.

As others have pointed out, the device needs some days and several charging cycles to achieve a good performance, besides, and very important, in settings>device maintaince>battery, there are 2 groups of apps that you can choose, always sleeping apps and unmonitored apps, there you can control their behaviour

I got better battery stats with Bixby not disabled. I may introduce and disable further packages one by one.

Yeah some of the Samsung apps and services being disabled will actually cause more drainage to occur.

having bad battery drain?

Hey guys. I used to have bad battery drain on my note 9. But after clearing the cache memory it is completely resolved. I'm not really a tech guy but this worked so well that I feel I have to share it with you guys.
For those who are new to cache clearing, it's quite simple.
Power down phone
Press and hold bixby button volume up and power button till you see the Android logo. Then let go of all
You'll enter a recovery page. Navigate using the volume button and select using the power button.
Choose clear cache and click yes.
Now choose reboot and you should have amazing battery life again

this does not solved my problem.. it's a bit better, but Android system is using too much battery I think.
is this normal? I can last a day, but It should be better

Have you turned off the background activities from the battery section?

There's a Samsung app "smart things" that needs to be disabled if you don't have a Samsung Smart TV or other "smart" appliance. There should be a message in the Samsung App Store!
This alone gave me 33% more battery life!

PS. I suspect that if you do have a "smart" device and set the service up you'll also have decent battery life!

Same here, clearing cache doesn't change anything, Android system and/or SystemUI draining the battery around 3-4% per hour, huge number of wakelocks (mostly PowermanagerService and mmc0_detect as stated by BetterBatteryStats), "doze/active with screen off" ratio 1:2 without touching the phone at all and I simply can't find out the real cause .
As far as I can tell the issue started with december security update, didnt have this problem before...

Been asked before but not a answered. What thing in galaxy store are you referring to ?

How long you had the Note 9 ? Mine was real bad 40 ish % i was losing over 8 hour span. That’s with my Note 9 in my pocket 4G on sync on that's it..
i didn’t even touch the phone and i was losing around 40% pure joke! i phoned up Samsung got a brand new replacement off them! One thing i did notice, as i had the phone for 30 days on the 28th day battery did get much better i was losing about 2% every 8 hours! I was about to cancel the replacement i thought f it. I might as well get a new one off them.
Your battery drain will settle down, try a couple of restarts. Also I did run my Note 9 in safe mode! Which is pointless if your trying to find witch app is draining the battery. But try running your Note 9 in safe mode, and use for a bit, Then boot back to normal mode it should get rid of the drain..
Forgot to mention. if I would turn on flight mode, I would have no battery drain! Try that when you go to sleep tonight to see if it’s signal network related battery drain!

I have it since end of August 2018, and has been rebooted many times since, so it should have settled down already It worked OK until december update, but then all of a sudden it has changed.

I'll try the safe mode trick, maybe it'll help. Thx for the suggestion.

The native Samsung App Store that mimics the google playstore, in my messages it had a "notice bulletin" to disable it after updates to the "Smart Things" App, you know like Samsung's refrigerator that talks!
Photo's by Sully using SM-N960U
I forget actually where exactly it/the setting is but it's related to this:
android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS
The battery opt page but truthfully I forgot how to get there, I'm coming from s5 Active and keep forgetting where stufffsss iz [emoji849]

I never got that. Thanks. But I just uninstalled smart things.
