I have been humming along on the P900 with the HyperDrive rom which just seems to work flawlessly and give good battery. Reading many posts that talk about battery life decrease on lollipop for not many more functions. I want a touchwiz rom because of the multiwindow functionality.
Does anyone have any comparison comments between a solid kitkat rom on P900 (like HyperDrive) to LL on the P900 (like civato ROM)?
Trying to decide if it is worth the investment to change it out and test etc. Thank you.
To be honest with you I was chomping at the bit for lollipop on the Note 4 due to the additional multiwindow feature of having the ability to swipe in from the upper corners to convert a fullscreen app into a windowed one. That function alone was enough for me to switch.
I've been on Civato's lollipop ROM basically since it came out and the experience is solid. I have no battery life complaints - to me battery life is less ROM dependent and more user software/use dependent. Everyone's mileage varies based upon load placed upon the device so manage your apps and you will be fine. For me i use Xposed module Amplify to control a handful of wakelocks and alarms to reduce standby drain, I also use Greenify to hibernate apps (and have ALL of the xposed based greenify features turned on). That combination gets me great standby drain of under 1% per hour (well under at times). Currently my battery is at 85% having been unplugged for 9 hours and having an hour of youtube streaming on it.
I'm not sure what features one may be fearful of losing on the move to LP but i don't think battery life should be a major concern but that's just me.
this tab should never lose 1% per hour idle. ever ever ever lol
it has a pretty large capacity, 9800 mAh, and is not cellular. I don't run any kind of hibernation or kill mods, and can go almost all day idle per 1%
I am using Hyperdrive, and my friend also has the p900 -- his on civato LP. same result
I do wish I had that multi window minimize option, but I like the stability, smaller resource footprint, and mod compatibility of KK. I use/do a lot of things that most other ppl who mod probably wouldn't though.
also the full screen Recents screen on LP would bother the hell out of me lol anything that goes full screen disconnects me from a couple games I play (as if I received a call or something). on KK with partial screen Recents, I can kill apps anywhere any time without having to minimize or close the current app(s)

Never say never. Depends upon what software people put on their devices that may produce wakelocks or frequently wake the device. Things like weather apps, multiple social media apps at once, multiple email accounts with lots of incoming email via push etc. I mean I totally agree with you, these tablets have a great kernel and sip power well at idle but OP brought up battery life as a concern over switching so I addressed that and arbitrarily tossed out a number and qualified it with a well under remark to boot. The typical reality for me is when I set my tablet down in the morning at work and pick it up 4 or 5 hours later the battery percentage hasn't changed more than a percentage point.

i don't use social media apps but my friend does. neither of us kept the email apps -- uninstalled from /system
I have like 20 push-notification enabled games and other background services including weather. he probably has about 50 or so push notification games. he's always struggling to find room to keep games installed lol point being we both have what would and should be perceived as monstrous wakelock
issues, but in spite of that still get great sleep times
idk how much we can credit the kernel for the long sleeps to be honest. I know kernels have a large impact on it but I've owned 7 android devices for 2+ years and all rooted within hours out-of-the-box
this one is a survivor, above all expectations I feel that the battery capacity is the largest factor here, because, for example, 10 wakes in an hour on a phone and 10 wakes on a tab, both with tuned custom kernels, should drain almost exactly the same power as each other. only with very minor differences
but that amount of power, is a smaller portion of the larger battery that was necessary for the giant screen. see what I'm getting at?

Definitely do yes and agree, the high capacity of the battery compared to other devices makes a huge difference in observed standby drain. I'm just not as comfortable as you are in speaking in absolutes, these subforums have far less battery related posts for a reason and that's the main one.

Took a look at my battery just now and I'm at 70% and the phone has been unplugged for 15+ hrs (I'll include a screenshot). Because of this, I thought I'd share my setup just incase it could benefit someone. This isn't a fluke, I've been experiencing this with the rom/kernel/modem combination for over a week now and I'm hesitant to change roms .
I will say there is nothing different about my battery life while using the phone heavily and that's to be expected. Like yesterday I was on my phone ALL day and the battery lasted about 10hrs (few phone calls, gmail push, HEAVY data use, low reception area for a while, GPS Navigation multiple times). The biggest gain comes from idle time. I use my phone pretty much like everyone else, may take a few calls, normal gmail push, data for streaming vids, twitter, fb... things of that nature. With other roms I've had up to 40% of my battery drain overnight while doing nothing! But with my current setup, I've gone about 36hrs (once again with normal to light use) without plugging the phone up. My setup is as follows:
AT&T Samsung Captivate
ROM: Phoenix 1.0
Kernel: Supercurio's stock + voodoo captivate kernel (Voodoo disabled)
Modem: I897UCJJ4
Theme: Custom concoction put together by me
Now I say I'm hesitant to switch roms, but to tell you the truth I really have no choice lol. I have a release date model Captivate and any non Captivate modems cause me to loose signal randomly therefore I must stick with Captivate roms. As sucky as that may be, I must say I'm not disappointed in this roms performance.
O, one other big thing I've found is that your launcher plays a CRUCIAL role in battery consumption. I've gotten the best life using Zune Home. The dev of that has two programs, Zune Home and Faded home. Zune Home is the one I used. It's very basic and some may not like it. I currently am using Open Home as my launcher and the battery life with it is great as well.
Well I thought I'd share this info just incase it could benefit someone out there. If this is the wrong section please don't hesitate to move it.
That's a beautiful thing. I'm sure lots of people are jealous! Luckily, I haven't had to much of a battery issue. I'm on Serendipity 2.0 and with heavy usage I last HOURS.
Not a big fan of either launcher and that does play a huge role. My launcher usually usually runs about 23-28MBs in the task along with Widget Locker which is about 5-9MBs.
I finally decided I would take some extreme measures to aide the BL of my Androids. I have an HTC Inspire and HTC HD2 with Nexus S Android. The HD2 isn't all that bad...much better BL than the Inspire, but I wanted to apply this measure to both phones. Will it help? Only time will tell.
I started by removing all screen widgets. Then I sorted the screen icons so that a minimum of homescreens were needed...got it down to 2 homescreens. Then I deleted all widgets without apps not able to be opened through an icon. Then I went into Applications manager and cleared and stopped all non-used apps and services. I also deleted all duplicate services such as OEM email accounts and their associated syncing....using add-in apps for them. (example: built-in apps and widgets like Facebook, Twitter are uninstalled or disabled and am using another combining app like Seesmic. Same goes for the email app)
What I currently have is an Android iPhone. I'm using only icons on the 2 homescreens. And this makes me understand why Apple refuses to use widgets and stick with icons...to preserve BL. I hope this will improve the BL of my Androids because it is purely horrendous. And it is horrendous with all Androids I've tried and used.
Until the recently announced battery tech breakthrough is made available, this might have to be how Android is used from now on. But I doubt these extreme measures will actually help.
What is the difference between a widget and an application?
An application is a single, whole program package that is loaded into the phone. Examples would be Tapatalk, the default Calculator, and Angry Birds.
An application can have one or more widgets in it -- a widget is an interactive thing you can place on the home screen. It can give you information, and you can tap on it to change what it says. A good example of that would be Beautiful Widgets, or the little Android guy that tells you about how to use your new phone.

@Marty, how long was your battery lasting prior to the "Extreme Makeover"? Mine currently will last me 2 days. Admittedly, I've not loaded a lot of stuff on the phone yet, and I have the power saver mode start at 70%...but I only need to recharge every other day.
My desire lasts around 2 days with moderate usage. But on a good day (read: many boring moments), it's completely depleted by the end of the day. My biggest battery drainer is whatsapp, if I uninstall the app my battery will last a LOT longer.
If i really need my phone to last for a long time (when Im on a big trip or on a festival) I always use JuiceDefender with a very strict setting. This is a big help, but not for everyday use
whats the point? Where ever you sleep you have access to a plug/usb w/e so whats the big deal ? how hard is it to charge the phone every night? even thought my galaxy s2 hold battery for 40hrs+ i never need that :|
Ive dont the same thing, I also found some build prop and init.d tweaks that improve battery life.
my brightness is always at minimum, i have only one widget,
My battery could last two days BUT i use my phone a lot. like its on for 7 hours with 4.5 hrs screen on.

Hilarious.
ther have been many apps and disucssions on BL. heres some common tips.
screen to lowest brightness possible setting. background data always off unless using market. disable -use wireless networks- options, no gps, no location. also turn off *back up my data*. wifi always off not in use. screeen timeout no more than 2 minutes. turn off animations and transitions. setcpu with moderate settings (if you can do a screen off profile it will be beneficial but beware Sleep of Death.) no live wallpapers. minimum widgets or none. minimum homescreens or 1. startup manger. adfree. location cache app. and battery calibration to get the most juice.
the issues seems to be alot with hardware the Htc inspire and HD2 have 1250 Mah Batteries , which are very small.
If some people are just like me... I can kill at 1800mah battery in 5 hours even at full charge...
I do everything on my smartphone. So anything to save the battery is a good way.
I have the Galaxsy S II and I've managed to drain the battery in 6hours of usage and since I'm not near a power source most of the time then yeah I need all the juice....
I don't sit in an office or am near a power source 80% of the time. I usually carry 2 spare batteries with me and a charger for them just in case.
Cheers! (Extreme power user).

Whats the point??
Here is my daily usage :
Alarm goes off at 6:30am (phone gets unplugged)
Blahblah (at work) reply to emails and messages throughout the day, on twitter A LOT (plume premium)
2 calls approx 30 mins each
Play some games at break and lunchtime (Drag racing KILLS my battery, a bit of plants vs zombies, grave defence HD and maybe some pinball deluxe)
more emails and twitter
another 20min call
a little more gaming while im waiting on customers (1hr or so??)
6pm go home for 6:30pm
BAM! battery is at 10-20% and i need to plug it in again.
this is a typical 12hr day for me and im sure others have longer days and i would appreciate not having to rush home (sometimes) if im expecting a call.
so as far as im concerned anything which will save some precious battery on my devices is appreciated.
btw i have reduced my homescreens to 3 and only have 2 widgets running and that has made a great difference to my battery life (esp. on the DHD)

Basically kill factory and carrier bloatware and you are getting better.
One thing I was amazed about was the eBook reader that comes with our Galaxy Tabs, and suppose others too.. it always working even if you dont have or use it.
And remember, the screen is what takes most out of your BL, always. Lower brightness? Get a better ROM with no bloatware and maybe undervolt the screen.
Homescreens dont change a bit. Widgets do, if they update a lot.. more than that notification stuff do. Like if you use a antivirus or antisomething, just check of notifications.. check of any unneeded notifications.
Vibration theorically is what consumes the most.. but since its not as used as the screen, you dont even compare them. But every little bit helps. Check off keyboard clicks and hepatic feedback - vibrations.
Wifi, bluetooth, data... don't actually consume much.. actually it's better if you leave a service stable on, than keep sleeping and switching it. So leave wifi always on, no sleep policy. But when you go out turn it of so it doesnt keep scanning all the time (unless you want to ).
Just like any PC, the more you install.... Just check what you got going on, learn how to check processes and services that keep on all the time, and there are some utils to help stop some crap from starting up. I use ROM Toolbox and Autostarts.. some stuff get activated just because you plug you device to charge!
DONT use task killers... dont let anything like that keep running... and no, GMail push notifications wont use any batt. Maybe pop/imap emails always pollling will use some.. but probably nothing compared to the examples above.
Cheers for my 2 cents.
EDIT: and after Xmas, remove those animated wallpapers!
Is Juice Defender a task killer? Not really sure what is it but I've been wondering about that.
Juice Defender Ultimate has been giving me about a 1/3 more time with screen on max. Why is my screen on max, because I was trying to drain the phone. It's on about 40% now which is still pretty bright. I wouldn't be mad to get more life but I think 20+ hrs with moderate use isn't bad. I think the most I did was search the net about 4 hours total. But I was also, customizing, so it the screen was lit for a while.
This is a TMO GSII I'm talking about.
There are a ton of things you can do, but the truth of it all is that our 3G/4G radios pull so hard they drain the battery, which is why you were on the right track when you disable active since, Facebook and Twitter.
The main two things I do, is
1. add a widget for turning off 3G or 4G (If its in your area).
2. Installed Startup Manager ( it disables startup programs in the unseen background, (my phone is rooted)).
by doing these two things I am able to get 17hrs+ on a standard HTC EVO 4G battery. Keep in mind the more you use the Internet the more it will drain your battery. So I only turn the internet connection on when I need it or the app needs it.
*I also only use one screen and remove unnecessary widgets but I find that doesn't help the battery life all that much, (my personal Preference)
*When I or my sons game on my phone I put it on Airplane more which turns off all Radios including the Phone (call/text)
*Drawback to turning 3G off, you have to wait a few second for the internet to come back on and MMS won't download through your messenger unless have it one.
I've been off the charge for 8hrs and my battery life is still at 65%
Sorry to be long winded but if I know anything its battery life
Completely agree. What's the point. Either you don't use your phone for ANYTHING, and watch the battery last for 2 weeks (literally), or you use it so heavily that it lasts only 2 hours....
I was sick recently, and as such couldn't use my phone (I couldn't open my eyes without getting dizzy, and even closed.... still was). Suddenly my HTC Inspire 4G used only 20% of the battery in 10 hours. The previous day, heavy mail, "friendstream" (HTC's facebook/twitter/etc app/widget), listening to music (well, audiobooks) for about 8 hours, and I had only 20% left. And i've found that overclocking the phone to 1.3GHz helps more than any other tweak.
Don't get me wrong, I'm obsessive about using my phone *and* getting awesome battery life out of it. But the ONLY way to true "maximize" your battery life is to *minimize* your usage. But then you might as well buy a feature phone.
And I know a few people with iPhones. a 3GS and a 4 and a 4S. They don't get any better battery life than I do. Heck, they get worse. Even under the same type of usage.
For me, the problem isn't the usage, isn't what's running, or what's loaded (but it does help/hurt). The problem is that battery technology has NOT kept up with consumer needs, or IT development. Your battery is dying as soon as it leaves the factory. Your battery is dying every time you change it. Especially when it gets hot. your battery dies faster when it's cold outside. We need better energy storage medium. Period.
Buy the biggest battery I can find on eBay....
Use the fsck out of my phone all day and have plenty of battery left.
Problem solved.

<<<< What he said
I don't think the use of WiFi could be overstated.
On my Skyrocket, leaving Wifi on (indoors), it'll sip about 1% every hour. I go out and have 4G LTE on, it drinks up about 3% every hour.
Minimizing widgets also helps. I saw noticeably better battery after removing my facebook and Latitude widgets.
The screen also sucks up the most battery. Turn it off on every occasion. Just turning it off instead of letting it shut off by itself has made a difference for me.

Battery technology has kept up with usage. However, battery size in relation to the power draw, has not.
Compare the size of the back cover on your phone, with the size of the battery. Why is the battery this tiny little 2" square, when the phone is 5" tall and 2.5" wide? Why aren't batteries the same height/width as the phone? Why isn't the battery the same size as the back cover? Why aren't phone manufacturers optimising the size of the battery (meaning, making it as big as possible)?
It would be so nice if phone manufacturers would stop with this stupid "race to the thinnest" crap, and started:
- releasing phones that are actually comfortable to hold like a phone
- releasing phones with batteries larger than a pack of matches
your battery dies faster when it's cold outside.

Actually, keeping a battery cool makes it last longer, not drain faster.
Hey guys,
I've been battling location related wakelocks from Gnow et al recently and finally came to simply using Xposed and WakeLock Terminator to block those wakelocks (which appears to correct that issue) and instead, immediately after, had audiomix keep my phone awake (despite no video/music/sounds). Upon research, I just keep finding wakelock after wakelock after setting to debug and fix - is there actually any way to get a dependable device? Am I doomed to always hope the night before my meeting is not the night the phone decides it's playing imaginary audio all night?
I love Android, I love the Nexus 5, and I can deal with 1-2% idle burn, I can deal with 4-5 hours SoT, and I can deal with leaving some location related things off. What I ABSOLUTELY cannot deal with is never knowing. For a device I'm paying well into three digits for that's supposed to take notes, make reminders, keep me in touch, and so on, it had DAMN well be able to stay on. I hated the iPhone in many ways, but dependability was something it never failed in - it did always work.
I've tried settings, I've tried debugging battery, I've tried custom ROM and stock ROM, three different kernels (counting stock).
So, tell me, what do I do to be able to count on my phone (without disabling everything enjoyable besides radio)? Please do not flame me for this, but I'm actually losing my patience fast. Any help is appreciated (and yes, I've checked forums, looked up the "improving Nexus 5 battery" posts, and what not - I realize I'll lose battery with High Accuracy location on, I realize WiFi drains it a bit, that's fine. I'm simply talking about fixing the bullsh*t stuff).
Thank you so much in advance.
Well how long does your battery last? And what does your battery stats say you get for usage and screen time?
The whole Android system operates on wakelocks, if you get rid of em all you'll just have a brick. It's the excessive ones that shouldn't be you need to stop

Sounds to me like you're too much into finding a problem
Audio Mix is actually a number of things, not just songs playing or Spotify etc. how long does your battery last ? i don't even touch wake locks or battery saving apps and i get a consistent 3:30 hours screen on time with 14 hours standby
Thats with a usage of :
Chrome
whatsapp
facebook
youtube
twitter
Google Now on
Location high accuracy
tasker - checking network location
" ok google" everywhere
manual brightness
mix of wifi/3g
etc
You mentioned a lot of wakelocks and didn't actually mention the sort of battery life you're getting
You may be right about the finding a problem thing. I'm probably a bit paranoid now, but I do get between 6-15% burn per out SoT and seemingly indefinite idle (Carbon + ElementalX is nice) when it's working like expected - it's just the inconsistency that drives me insane. If it was ALWAYS 2%/hour idle burn, I could learn to deal with that. It's just when I go to bed with it at 30-40% and wake up with it dead that I can't afford to have happen.

It's difficult to be consistent all the time with a phone, the radio in a bad area can kill your battery just as you mentioned... That being said 40% overnight is insane
I seem to have fixed the wakelock by removing DSP Manager and blocking location wakelocks. I'm a little OCD with technology... lol
AudioMixIn? That's the OK Google hotword detection feature.
Battery has been consistent for me. The only time it isn't is when I'm in an area with weak signal and trying to use data, then power usage can go up 10x as high as normal even just idling. Otherwise, I always know what to expect but I have turned paired down the features that tend to drain uncontrollably when the phone isn't even being used such as WiFi Locations and Auto Syncs.

That shouldn't ever happen (never has for me), but if you want it to be full in the morning it's best to plug it in.
I wish battery threads would die a long, slow painful death.
If battery threads had a human form, I'd torture them like Theon in GOT.
The answer? Every device is different. No battery life from one user will be replicated by another user.
BOTTOM LINE.
There are too many various factors for battery to remain consistent as others have stated. The only thing you can do is attempt to be resourceful and your battery life should remain decent to high all the time.
Lower brightness, disable unneeded features, uninstall non-used apps, use Greenify on Facebook/Kik, use 2G radio when not connected to WiFi if you can deal with it.

Anyone have better battery life on stock kernel than on any custom kernel?

Yup, haven't had a custom kernel beat my SoT and idle drain, and tried most of them. Including wakelock blocking, underclocking, etc. Stock remains best by far, here.
Ymmv and sure some kernel fans will chime in and claim completely otherwise, and that's just fine :good:
For now enjoying 10+ hours of SoT and draining 3% per night being idle using the amazing stock kernel
I'm getting about the same, MAYBE a little better on EX Kernel. I use the custom kennel for features usually.
* Increase vibration strength
* Lower minimum MHz for less per drain when idle
* Increase Mac sound volume
* Disable swap file and Zram
* Increase read ahead to 2048kb (ideal with 32gb or more storage)
With the 7 pro I'm getting better battery then my op6 and I have forced 90hz all apps enabled 24/7 and resolution set to auto switch.
i do kernel tweaking on my own but not a custom kernel. Im on the latest h2os and i get 9 hours sot average. idle drain overnight for 8 hours is about 2%
Personally I don't run a custom kernel for power savings, I run it for wireguard support. The best way I've found to increase battery life and reduce idle drain is running xXx magisk ROM and debloating the crap out of the OS
Yeah, best battery and performance balance is the stock kernel.
Stock kernel...I don't need to look at the screen for 10 hours...doing what I do is more then enough to last for more than a day...
just hit 50% battery and I'm at over 6 hours screen on time
2 days 5 hours off charger with 7 hours screen time.
I don't know how some of you can achieve 10h SoT I literally tried everything - all kernels, debloaters, used Swifted to force most of apps to run in dark/black mode, used Automate to toggle off wifi/BT/kill unused apps that use resources in background (like fb etc), some magisk modules, kernel tweaks - I did all of that with all sorts of combinations (not all at once) and basically I couldn't improve bettery life by any noticeable margin, getting 6, sometimes 7 SoT, my goal was 8-8,5.
I don't any heavy lifting - main usage is Hangouts, Gmail, Facebook (maybe that is the killer?), Messenger, Chrome and sometimes other (telegram etc) - Never any gaming nor heavy programs.

For now enjoying 10+ hours of SoT and draining 3% per night being idle using the amazing stock kernel

I'd try sticking to the stock kernel, the problem is that OTG doesn't work properly.

Exactly what doesn't work properly? Can't find any peculiarities.

I don't know how some of you can achieve 10h SoT I literally tried everything - all kernels, debloaters, used Swifted to force most of apps to run in dark/black mode, used Automate to toggle off wifi/BT/kill unused apps that use resources in background (like fb etc), some magisk modules, kernel tweaks - I did all of that with all sorts of combinations (not all at once) and basically I couldn't improve bettery life by any noticeable margin, getting 6, sometimes 7 SoT, my goal was 8-8,5.
I don't any heavy lifting - main usage is Hangouts, Gmail, Facebook (maybe that is the killer?), Messenger, Chrome and sometimes other (telegram etc) - Never any gaming nor heavy programs.

I think some of those messaging apps (or ones that require syncing or wait for push notifications) are the cause.
You wont see the battery page showing that they consume so much battery because in a way they dont (as they are not in the foreground or doing any heavy computation). But i found that these apps prevent the phone from deep sleep.
You can find out by using things like Better battery status to see the wakelock/alarms of those apps. Some of apps wake up the divice periodically so frequently....
But on the other hand if you want to get notifications from an app and it is poorly designed (drains unnecessary amount battery), there is no way to avoid it. But if you just use jt occasionally and dont need timely notification, try using Servicely to disable wakelock/services of the app (requires root and may break the app, but you can just enable those disabled things to restore the app).

Yeah I suspected that as well and did track Wakelocks. I used Automate to kill Messenger and FB in background when the screen is off, also tried few other tricks and amount of % of deep sleep while screen is of was better - starting from 30% awake while screen off to as low as less than 10% but... Battery train in idle was the same and generally battery life didn't improve at all... Strange but True. That's why I went back to all stock without any tricks..

hummm...well right now im on blu_spark and this is the best battery life i am getting. My set up is described here:
https://forum.xda-developers.com/oneplus-7-pro/development/kernel-t3944179/post79844206
i think im stuck in the same shoe as you cus i rely on Wechat,google sync and a Bluetooth fitness band so the device is going to use quite a bit battery but i managed to get this far...
And battery life is what i require most out of a phone lol
here is a screen shot of battery usesage, its still early in the day but.
I expect screen on consumption will go to about 7.5~8% / hour when the day goes by, like usual.
One interesting thing is that, lol, i never tried stock kernel lol And seeing (in this thread) how people get good sot with stock kernel makes me wanna try it lol will give it a shot over the weekend

Well yours stats look great, I would like to have stats like that as you said, using BT devices connected and messaging app I know I will not hit crazy SoT but still I want a bit better cause as you said battery is like too 1 priority for me I see we are very similar users thanks, in fact I didn't try blue-spark so far, I will give it a shot! I know standy drain will be laso related to Wi-Fi / 4g coverage (low signal = big drain) but I don't think I have such bad signal so I won't to get at least not more that 1% idlle drain per hour and 8-9% on screen and I'm good.
BTW what's your screen brightness usually?

yea lol our needs are very similar.
I just set screen brightness to auto, which changes between 30% ~ 50% when im indoor, whihc is like 90% of time. Then the rest is outdoor at noon lunch time during which screen goes to full brightness for a while.
Oh i also use OLED friendly wall papers and black theme in apps if available.
Ok so your screen brightness and setting (dark theme etc) is same as mine, so this is trsnge why I'm getting almost 2x worse drain... Must try this kernel.

i also forgot to mention that, with PlusBeat, the screen off drain goes up to 1.2 per hour.....and that is because of the wakeups...so i disabled it lol
7+ hours
Hi,
I read several posts where people talk about 7..9 hr SOT I start to doubt about the quality of the battery inside my pixel 4a.
Mine is usually depleted around 4hrs, no special apps no gaming only browsing, some YouTube, spotify nothing special. Most of the time using WiFi and good/moderate cell phone coverage.
I already disabled screen notifications, AOD display.
And not sure what else I can do to improve the standby time.
Any tips?
30wakups /hr seems a bit high?
Makes no sense to discuss alarms/wakelock/wakeups in the context of SOT. Besides, the former has little correlation to overall battery life with modern Android builds.
Panel brightness is generally largest variable in perceived battery life which is one reason comparing SOTs is problematic unless that variable is controlled. Consider your settings to see if it's a factor.
Radios (signal strength) and CPU are the next biggest consumers. SOT will almost certainly be less for active gamers vs casual browsers. Connected devices (eg: fitness band) can also take a toll. Make sure GPS receiver is only on when needed. A dirty finger scanner or stuck proximity scanner (rare) can be huge drainers.
If all that seems 'normal' the you may indeed have a bad battery. Device should be under warranty; reach out to Google or seller for a replacement.

Thanks for your detailed answer, I'll perform a test with lower display setting, although I already think this is not the issue here. Because over the day screen off I also experience battery drain -2,5%/hr.
Any test I can perform to check battery performance?

Ah - that's a different matter. I can easily score idle drain rates <0.2%/hr on my 4a. Biggest culprits for idle drain are social and fitness apps that intentionally evade Android's native power management tools. Verify 'adaptive battery' is enabled and no unexpected user apps are shown as exceptions under 'battery optimization'. Restart your phone in '"Safe Mode" (Google for instructions) to see if the idle drain persists. If still no joy install one of the legacy battery monitoring apps like BBS or GSAM (available in the play store) to see if they surface one or more culprits. You can also post a BBS idle dump in the BBS thread where 'good seminarians' will offer commentary on what may be causing the drain.

0.2%?!? Damn! I always look for and am happy with less than 1%. Crazy. You must get days out of the battery

That's idle (screen off) drain rate with only SMS (text) exempted from what is commonly known as 'doze'. Stock A11 configurations; device is not rooted nor have I gone to any length to optimize behaviors. It's a breath of fresh air after many years of 'tuning' hardware, kernels and ROMs to my liking.
Those running a handful of active social apps along with corresponding notifications will see substantially higher 'screen off' drain rates.
Yes, I can score "days" off a charge if I use my phone sparingly. Typical use is somewhat different; I usually recharge every other day with 30-40% remaining. That's obviously much better than others report because I use my phone only when another option (tablet or laptop) isn't readily available.
I usually use my phone 3-4 hours a day because I work 10 hrs but when I go to bed there's still 60% remaining. On the weekend I charge once a day and use my phone constantly (youtube/reddit) with a remaining 20%. Battery definitely doesn't last as long as my old 7t but honestly I have no trouble with it with dark mode/adaptive battery/auto brightness/ restricting permissions to "only when app is running". Like others have said I'd check your battery health and maybe tinker with your settings
