I amusing Battery XL at the moment, can't see that much energy savings..
Not using it
Seriously, though, there is a thread in the General forum that goes through many of the ways to improve battery life. I personally have found that battery savers just do not do what I want, and sometimes they use more battery when installed. I like to set it all manually. It is a lot of work to set up, but the battery savings can be great.
A lot of it requires root access, but I think this is a must in any case, even if only to be able to set up a firewall.

It's useless,
there're steps for saving batteries.
1. Reduce brightness to less than 30% during indoor, this should be enough for most people;
2. Turn off mobile data and use only wifi whenever you in wifi-spot
3. Don't always use live-wallpaper
battery saver apps are designed to kill apps/processes to reduce battery usage. however, this ends up being a waste of time as these apps and processes will often reopen themselves after. so you end up in a boot-kill loop for every app, which ends up using more CPU cycles which ends up killing the battery faster.
you're better off leaving these apps in the background since they dont use CPU cycles when theyre inactive.
if you want to save battery, turn off wifi and bluetooth when youre not using them. otherwise your device will constantly waste battery by trying to ping local wifi hotspots and bluetooth devices.
turn the screen brightness down and use dark backgrounds. on amoled displays, black means LED off which means no power consumption. white means LED on which means full power consumption (a white screen on an amoled display consumes more than twice the amount of power an LCD display would use).
dont use live wallpapers.
turn off mobile data when youre not using it. or if this is inconvenient for you, disable any widgets that constantly use your data (ie. weather widgets) or set their update interval to every 3 hours or so (lets face it... who needs to know how much the temp changes every minute...).
I hate this feature, my tablet is basically useless when battery drops below 5% especially outside/during the day. Further more my battery stays at 1% a lot longer than it shoud, so it feels like it's dimmed roughly at 10%. There is an app adjbrightness that can do this on rooted galaxy s4, but won't work on my n5120 rooted stock 4.2.2. (All battery saving features are turned off, and brightness slider in notification disappears when battery below 5%)
Any way to disable this irritating feature?
Don't know if it's possible, but I'd love to see a fix too.
The only thing I know is dump the stock rom, and switch to AOSP.
You can disable DVSM with Xposed framework and Wanam Xposed. That will correct the odd nature of your battery being slow at updating percentage.
I normally do not operate the Note 8.0 below 10% so I never see that.
Also I came across an xposed setting to set the minimum battery level and another to disable low battery alerts... maybe the screen saver mechanism is part of the alert process. Donno.
Recently my N7(2013) will shut itself down when the battery is low (about 10%) without any warnings, not even the "Shutting Down" dialog that it should show whenever it shuts downs (except for the usual low batt warning when it reaches 15%). After the shutdown, I cant even turn it back on not even the screen, nor the low batt (waiting for charger) screen is showing up until I plug it into a power source the it will show the charging screen and then I can turn it on again.
Its been a few times now, not sure its a hardware or software problem though. It shouldnt shut down when it still has 10% in it right?
Attached is the screenshot of the Battery Usage that shows the battery level shots down to 0% immediately from 10%.
Nexus 7 2013, Stock, Not Rooted
Are you using a battery monitoring program (battery doctor, better battery stats, etc)? If so, look in their settings, to see if they are set to shut down @ 10%...

Nah I don't trust these apps so I don't use them. Moreover I'm did not root it so even if I use them they shouldnt have the permission to shut it down
Simple fix
It is an issue I have suffered with a couple of times and it appears we are not alone. It seems that the battery calibration is out of whack. When you charge your nexus up does it stay at 100% for quite a while? I
tried factory data resets amongst other things and nothing worked. I stumbled across a thread with a really simple fix. Turn your tablet off for 2 hours. Then turn it on again. Mine miraculously lost 26% of battery in that time (from 100% where it had been for 8 hours down to 74%). Then it started to use the battery at a normal rate. Working fine now.
My battery will completely drain after <10 hours while the screen is off!
However I was able to find out thatquickgooglesearchbar is always the top app.
Those screenshots are a bit old but it's still the same thing, I did manage to root it today, and I was testing Greenify which did nothing even with the Xposed modules, service disabler apps just did not show that specific service for some reason. I was able to remove the widget with Xposed GEL settings but it was still running even though the widget wasn't there.
So can someone please help me out here, maybe the search bar isn't the problem but I just want some battery life.

search and install betterbatterystats (read the whole first post) and it will tell you if its wakelocks etc.
Service disabler apps will need a setting to show system apps (or something similar) ticked or switched to etc.
greenify system apps in greenify also needs to be selected. You may also need to cut wake up paths to get it to stay greenified.
You could alternatively delete the apk of hibernate it (byfar the easiest option of all this).

I don't need betterbatterystats, I have battery Battery Historian, check the screenshots, It's clearly the search bar, on my other phone It isn't shown as a top app.
Also I went in the system folder /apps and there was no googlesearchbar, or in any other system apk remover tool, perhaps it was removed by another app, but it's still for some reason running.

Your 3rd image shows googlequicksearchbox had 370ms (milliseconds) of wakelocks over a 9hr period. I really doubt that is your issue.
If it is your top app, then it is probably because of Google Now launcher listening for OK Google spoken keyword.
I seriously doubt that is your battery drain problem as almost 90% of people probably have OK Google turned on and are using Google Now launcher and only a very few have serious battery drain.
BTW wakelocks aren't the issue usually. In the past it has been "partial wakelocks" which means an app locked the device from sleeping, but never released the lock, so the device never goes to full sleep. If you see some app with partial wakelocks or if you see some app with hours of regular wakelocks then that might be an issue. Minutes or microseconds of wakelocks are inconsequential.
I suggest you flash factory image and install your battery tester only. Turn off wifi, bluetooth, nfc, cell radio. Test the drain overnight. That is a baseline for the minimum drain your device can have. Then enable what wireless stuff you normally have turned on. See what that drain is. Then start installing apps and see what that drain is.
If you have reasonable/expected battery drain with stock and everything turned off, then it is just a process of elimination to see what is causing your battery drain.
If you can't get reasonable/expected battery drain with stock and everything turned off, then you probably have a bad battery.
For the record, my overnight battery drain with everything turned off is 0-1% With wifi turned on about 1-2%. With wifi+cell about 2-3%.
IMO the biggest drains for standby are wifi and/or cell signal related. Either bad signals or apps sending data in background or apps that are polling all the time.

Factory reset didn't do anything a few days ago, the results were exactly the same that was when my phone wasn't rooted, so I guess I should return the phone, and get a new one?

What is your battery drain per hour with nothing installed and all wireless turned off and everything stock?
I'd only return it if that is significantly more than 0-.2% or 1% every 5 hours.
Otherwise it is something you have installed or something to do with the signal and how it interacts with your phone.
Once you start installing stuff or turning on wireless (wifi/bt/cell) then it is no longer purely about the battery and there are more factors that need to be isolated independently.
You really need to establish a baseline to see what the minimum battery drain is. Then you can determine if the battery is the problem or something else.
If you just install everything and turn everything on, there are too many moving parts.

Okay, I now have android N, and my battery life seems to be better, I will leave mobile data off. I will see tomorrow if my battery life has changed.
Do you think I should use Adaptive brightness for more battery life?

Which battery life was the one you think you have a problem with, standby or in use? IMO for in use battery time this phone is about average. Your title of "wakelock" made it seem like you were concerned about standby battery time as it doesn't matter if there is a wakelock if the device is already turned on and in active use.
When turned on, the screen is probably the number one thing eating power, so adaptive brightness could help, but if you are in a bright area, it might be worse than if you fixed the brightness below max.
Even if you have adaptive brightness turned on, the slider scale still is useful as you give the adaptive brigthness mechanism some idea what level of brightness you feel comfortable when the mechanism detects dark, med, bright situations.
One of the worse things for eating power is for the cell radio to be turned on but have no signal, like inside office building or just a bad signal area in general. The reason is the cell radio is power efficient once it establishes signal, but when it is searching for (or loses) signal it uses a lot of power.
If you are doing a lot of disk activity like taking video or hdr pictures, it would probably help to have your userdata unencrypted as this device does software (kernel) encryption and doesn't use the fast/more power efficient co-processor.

Standby is the problem, on screen times are good enough.
Anyway, I don't even know what to do at this point. Android N didn't help enough (cell data is off), I guess I can flash Android 6.0 again and then try to fix it using apps...
What do you suggest I should do, I'm out of ideas at this point.

Have you set "WiFi on during sleep" to "Never"? in the Advanced WiFi settings?
In the original release, there was a bug where WiFi would stay on even if you had set it to "Never" draining battery in standby.
Somewhere between MDA89E and MHC19Q they fixed it and WiFi will go to deep sleep after being in standby for a while, but they introduced another (or exposed existing) bug where WiFi will not resume after coming out of sleep, unless you cycle WiFi off/on. So you're standby battery should be better with this setting, but it'll be a little more annoying when turning on your device.
Does anyone know where to adjust the low battery notification percentage on Oreo? E.G. to alert at 5% instead of 15% etc.
On a previous Nougat handset it was under settings -> battery. I've dug around and haven't been able to find it.
If not inbuilt into Oreo, if there is an app to configure low battery alerts at a certain battery percentage, I'd be fine with doing that if need be. I'm rooted if it needs to be a root app.
Thanks all.

There is no native setting on the P2XL. There are several battery alert type apps in the play store. There's probably even an adb method to adjust it, however, I don't know what that would be.
Going to battery saver is only native way I could think of I never see low battery since I'm usually around 50 percent when I got bed the battery is happyer when charged more frequent then letting it die then charging unless you are doing it 5 times a day for 6 months
