[Q] Why does android's standby time suck?

I've used around 5 Android phones (starting from 2.1 now up to 4.3) and for some reason, they all have a pathetic standby time. When I say standby, I mean when you press the power button and it turns the screen off and you don't touch it. Why is android the only OS that has this problem? WP, fine. IOS, probably the best one (only good thing about it).
I've tried different kernels, using no apps from the play store at all, turning off Google's location service, using greenify, and a bunch more. My battery still drops to ~70% at 4:00 starting at 100 at 7:00. When I briefly had an iphone and windows phone, I always was amazed at how my battery was around ~90-95% at 4:00. I know most people actually USE their phone during the day, so its probably not as noticeable.
Does anyone know the real reason for this? By real, I mean the deep down reason for this. Is java just a hog?

I think the main reason is the backround apps that are running. I used my old sensation just as a phone and so I deleted all the apps from it (Facebook, Viber etc.) and the phone lasted 5-6 days on standby with a 1 year old batery. Before I removed those apps I couldnt get 2 days on standby. I think backgrounfd apps in Android are allowed more "freedom" so they use up the CPU while on standby. That is my experience and opinion.

Yeah I thought that, but I said I tried it with no apps installed. Same thing.

Weird, I don't experience that kind of massive stand by drain.
If I turn my screen off or let it time out, my phone can sit for a almost a couple of days before it shuts down - sometimes two full days. This was true with my Nexus 4 and Galaxy S3, and now the One.
So I have no clue what you're talking about, generalizing Android like that.

i disagree
My battery drains 1% every six hours

I'm generalizing Android because I was talking about "Stock" android. Not what we do here. I really have to find a fix for this. I dont know what I'm doing wrong here.

Mine also has great standby time...

I am talking about stock Android as well. I have had great battery life with my last three phones.

I've had no such problems with "android" in general. Some roms / apps yes. But after fixing those issues it was pretty much what would have been expected / what reviewers/other people get.
I would recommend getting something like gsam battery monitor and let it run at least a day and then post some screenshots. Maybe we can give some concrete advice then.

Terrible Standby Battery Drain

I was super busy today so I barely looked at my phone so I was expecting my battery life to be in the high 80s but when I looked at it, it was at 31%... with only 28 minutes of screen on time...
By percentage the biggest drainers are Google+ (13%) - which I do not even use... -, Standby (10%) and Screen (6%).
I'm rooted on Pure Shamu with Elemental Kernel (for RGB control, no other mods with the kernel), if that matters. I can't think of anything I've enabled that would kill the battery so hard.

Sounds like a wakelock in either the ROM or kernel to me.

I'm having a similar issue with Lean Kernel.

Yeah, Google+ had almost 9 hours of wake time and 2 hours of CPU time. I have no idea why, I don't even use Google+ and I have location services and photo backups disabled.
I've completely deleted the Google+ profile though and I've disabled account syncing for everything other than Gmail. I'll see if that makes any change tomorrow.

Fwiw G+ plays fine on my device and doesn't nuke the battery

Delete Google+ , I've had the same issue on a note 4 aswell.

if you're not using G+ why not disabled it.

How do you disable it, it is not listed as an app.

Or uninstall the app. No point in having the app installed but disabling it, it'll take more space.
This is why I prefer minimal gapps, Google includes so much bloat ware.
I also recommend using app ops to deny access for keep awake on play services. It'll help with standby battery significantly.

i found this foe google play services last night, so i disabled iys background data use. i dont remember being allowed to do that for google play services. which i also assume will keep it from waking the device when its sleeping(since data is not allowed).
anyways, to the op, do you have photos uploading to the cloud? if so, disable that service, thats what uses the g+ app when you dont use it.

No I had photo uploading disabled. But I disabled Google+ all together before I plugged it in for the night and I'm having much better results. I've only had about 9% of battery drain with mostly standby and some light browsing before I got out of bed this morning (I've been stuck at my computer all day so I haven't needed to use my phone much). Much, much better than the 70% drain I got yesterday from the same.
Since uninstalling isn't a default option in app setting for G+ I imagine I'd need to download something with super user access to do so? Any recommendations?

I am getting killed by the Google Play Services. It was fine till yesterday. Suddenly from today it starts drinking battery!

This is a cool phone. Google has released new software (lollipop). But it just really sucks that a phone with such a beautiful ui and really cool features is such a mess. And yes this os is a mess. Most of us are disabling features such as ambient display, google apps, location etc.. just to be able to last anywhere from half a day to a day. Really depends on how much a person has had their screen awake and how much is disabled to attempt to make it through a day. The battery is just not large enough for the 4k display. If everything were operating correctly I would feel like I'd spent my money as well as I ever had on a mobile device. What is the value of having a 2.7ghz processor if we have to under clock it? I'd like to use the speed of the processor but I slow it down also as I am fighting for battery life as much as I can. Today is the first time I've used battery saver and my experience is that it helps tremendously on my phone personally. But it also ruins many of the reasons I bought the phone. I like the animations of lollipop. I've always reduced animations to .5 through developer settings. I hope Google is seriously trying to iron this out. It's a big deal that all of us are fighting for battery life and Google apps gone wild are hurting many of us. As far as I can see my opinion is this os is a great concept but needs much work to be considered anywhere near as efficient as KitKat was. But the real question after all I've said is Have any of us that purchased a nexus phone never had to fight for battery life? We knew what we were getting into when we bought a nexus. Things will get better. I just wonder when and if this screen will ever be controllable with IMO such a small battery for such a large 4k display. Enjoy your nexus'. I am the best I can fighting for battery life.

Just to be clear, its not a 4k display and I'm averaging 4.5-5 hrs screen on time without disabling anything

Normal is relative. Is it a bit on the low side? Most definitely. Normal? Maybe. It really comes down to the apps you have and how you use your phone. I personally get about 5hrs SOT and I'm fine with that. Standby drain is more important to me than SOT. There are battery saving tips and trick you can try to google or youtube.

My phone drains like 3% per hour on IDLE. I don't have AoD nor anything in particular that should be causing this drain. I have no idea why. The battery life seems to be fine for actual usage, but teeeerrible for AOD.

3% per hour no AOD is bad. You have an app causing major drain for sure. You might have to deep dive in your battery stats to find the culprit. Last resort would be safe mode to see if your able to reproduce the issue. You should go to the battery life thread and ask around.

I'm not sure what it could possibly be since my old Note 8 did this too, but it alternated every other cycle or so where it would drain less than 1% or 3%+. I exchanged it for a new one and this issue is happening again except it was completely fine for the first week or two. There was no app that I downloaded between the time that it was fine and not fine.
I guess I'll repost this in the battery thread.

i am not losing battery overnight as much as you guys, my problem now is i can't get 6-7hrs of sot anymore, 4-5 is as much as i get, and it's only 1 month old.

There was a thread about Android OS drain.

I miss my note 4. I use to get around 5-8 sot. With this phone only 3 and half hours. That's with everything turned off too. On my note 4 I had just about everything turned on. Will be waiting for the note 10 to release then I will buy the note 9

Is my phone battery dead?

I got my note 9 two months ago, I downloaded Accubattery today to check battery life then I charged it from 7% to 100%. I was shocked when saw that the battery capacity is reduced a lot! The app says it is now 3505mAh !!! With only TWO MONTHS OF USE !!!
Is that app accurate ?
I play PUBG a lot but that is why I bought the phone; because it is powerful and SUPPOSED to deal with that much of usage !!
I also use VPN all the time
I use 4G only no wifi no NFC no BT
When sleep for 6 hours with mobile data off .. standby consumption is about 2-3%/6 hours
Any suggestions ?

Read this topical about battery on Note9 and do not use any battery monitoring program. Erroneous readings.

Accubattery is your problem my friend, not your battery.
Enjoy your device, stop worrying that much about the battery.

Two hours of screen time presumably playing a video game most of that time, and still have 70% battery remaining. Iphone users would kill for that kind of battery life. Think about it, 2 hours of game playing gets you 30% battery drain, then I can surmise that you can play nonstop for around 6+ hours before your battery dies. That's excellent by any standard. I remember a time when 2 hours of screen time was considered decent, and that doesn't include playing a battery intensive gave. And that time was really only a few years ago.

It seems I'm over-concerned about the battery stuff.
Thank you all.

Question High temperature ~ Low battery life?

Hello guys, i recently bought the Mi11, this is my first flagship phone (at least in terms of hardware) and i'm not used to a soc like the 888 that require this much juice.
Since the beginning i noticed that the battery wasn't so great, in particular the drain was quite high (almost 1.5%-2%/h even if completely untouched) and the phone tends to get quite high even with extremely light use (telegram, whatsapp, youtube at most), however i don't have a reference of what should be considered hot for this kind of phone and i initially assumed something was wrong with my battery.
Do you mind sharing the temperature of your battery during those very light scenario? Just chatting on telegram and similar?
Yesterday with around 22t.amb i reached 35C just by chatting on telegram!
At the same time. temperature during benchmarks like antutu seems fine...

I honestly don't know, a friends of mine is telling me that the range 30-35C is more than fine for this phone during extra light work but i'm not sure.

Make sure you read the comments before doing it. Some components I would consider important core components are being removed by some of their commands. Make sure you consider the implications before copying any commands from there - one of the commands listed in their thread would probably make your NFC nonfunctional, for example.

I don't use NFC and yes as I stated you don't need to implement all of the settings and choose what suits your need. And this will solve your temperature problem. As it did solve mine.

Running warm all the time with high standby/idle current draw means you're needlessly prematurely trashing the battery.
Find the power hogs and tone them down.
Anything that's polling the internet every minute at idle needs to dealt with; that's one way to find the offenders. Karma Firewall uses almost no battery and is freeware. Unfortunately it's logging feature won't work on Q and above. Perhaps there an ADB workaround, don't know as I'm still running on Pie.
Goggle Play Services, Google Backup Transport, Framework and any cloud apk are prime offenders. Disable these as needed well as Google Firebase unless you want bloody Google to inventory your database!
Disable all carrier, manufacturer and Google feedback.
FB, WhatsApp, Twitter, Instagram etc... ditch this trashware (you were warned).

I'm appreciating all those advice guys, i don't want to be rude but again, my question is much more temperature related than battery related.
I still don't know if what i'm having should be considered normal for a flagship phone (in particular with such a ****ty soc like the 888) or not.

It's not normal on an optimized phone unless doing a cpu intensive task ie some games, malware scanners etc.
If a you have apks using massive amounts (enough to warm it) of cpu cycles doing nothing constructive it's killing the overall performance needlessly. Using cpu cycles and probably internet bandwidth as well.
If it's running warm when idling... you got power hogs

Actually, what blackhawk is saying, i agree with that 100%. Those are the batt consumers. This is an issue since android 9. Your heating comes from the google framework and services.
However, i do not agree on the part that this is not normal. Why? Simple, every phone with the newest just-released-hardware has this heating problem, based in the android framework. I have seen this with my phones all the time, oneplus 6t a lot of trouble, xiaomi mi 9, oppo, and even samsung. The software and the framework is just not fully ready to be launched and actually takes a while for the company to solve it. All the phones i mentioned were bought on the release and all was fixed by fixing the google framework, no more random heating or batt drops.
