Battery Drain on 9.0 Pie

Hi people,
Can someone give me and opinion of the battery drain with a note 9 on pie?
I bought my Note 9 four days ago and updated to 9.0 pie right out of the box, I think that battery is still optimizing for usage but I find it very bad with battery life and SoT. I'm posting a screenshot, if you have some tips ?

I'm with exynos, 50% brightness display, exynos version, Bluetooth off

You answered your own question! Battery is still optimizing for usage! You have to give it 10 or so days before it battery gets better! Also turn off Wi-Fi, Bluetooth, 4G, Sync, turn the screen off turn everything off lol messing with you 2/3 weeks mine took to settle down!

I'm having the same problem. Android System was waaaaay lower before. It's always at the top of the list now. :/

There's plenty that can be done, especially if you have the exynos version of the phone.
-Unlock bootloader and install Dr Ketan's rom, it is fantastic.
-Then apply endurance kernel.
-Use Magisk manager to apply module: Universal GMS Doze
-Use Mtweaks to apply a few kernel tweaks
I haven't gone this far just yet as I'd like to see how the phone goes without it for a few weeks but you can also install greenify or if you want to really get serious, greenify xposed module. Personally I find the battery life of the note9 to be fantastic but you must keep in mind that the screen is enormous and hi-resolution. Whenever you are using the screen, especially at a high brightness level the battery is going to drain - it can't run on good intentions.
Try turning down the brightness. If you are absolutely serious about battery life over everything else, you can disable auto-sync, remove the official facebook apps if you have them and replace them with faceslim and lite messenger and modify the notification settings.
Doing all of the above and only turning the phone on when you need to make a phone call or use navigation etc should net you an easy 4 days+ of useage but then again, you may as well have bought a $30 powerbank phone.

Tripping Knox hardly sounds like a good idea if I'm honest.
If your Android System is high then something in the background is wrong. You could try clearing cache then give the phone a couple days to settle

Battery life varies significantly with any phone and any version of Android.
Often we assume, wrongly in my opinion that a very large factor in battery life is the version of Android , hence the numerous posts on this forum who wish to or have gone back to Oreo, for reasons I consider delusional.
What apps you have on your phone and how often you use them are significant, playing games that use lots of cpu and gpu is going to impact battery life.
Web browser and YouTube rather less so.
I have experienced lower and higher screen on time and standby time with the same apps and version of Oreo, and Pie (both on beta and released)
I am on Exynos Note 9
Bought and used since release date Aug 24 2018, haven't used so called battery life friendly charging (20% to 80% etc)
Can run battery down to 0% on occasion and charge to 100% using fast charge, often left on charge overnight.
Yes there are some optimisation that may help and I use a few, I couldn't tell how much they help though as just varying usage is a greater factor in my opinion
Battery performance from yesterday

Mi 9 lite battery drain \ cpu usage miui 11

Hi everyone,
I received my phone a week ago.
After first boot it updated to miui 11.
I noticed a day later that the battery is getting empty fast. Much faster than my old redmi 4x.
I figured out that the CPU usage is never under 19% @ 595mhz
I testet that with different apps that show the CPU usage.
In case of that the phone also never get into deepsleep and the battery drains and drains...
Is here someone who can help me please?!

Miui 11 is full of bugs, scrolling lagging everywhere... I recommend you to stay on Miui 10. I have around 9h screen on time with brightness on half

Sounds great! But how can i go back to 10?

First put phone into fastboot mode, then check antirool feature with command fastboot getvar anti if you have
anti: 1 it's all good, after that you need to download from Miui page proper recovery rom, put zip on your phone storage and then flash via Miui system update in settings. Don't flash wrong rom it can hard brick device if you have locked bootloader, also remove password for screen, fingerprints, all accounts, miui cloud

Thanks for that! I´ve downgraded to MIUI 10. But the CPU usage is still never under 19% . If the battery now will drain not as fast as before i will see., but i think it will be near the same.
Maybe you can do me a favor and check with the app " CPU / GPU meter & Notification " if your CPU is going under 19% usage. Maybe it is a issue with this kind of apps....

Probably apps have problem with readings..

I think below 19% when device in deep sleep or battery saving mode. Dont know about that app, maybe just reading in relatime. There is a case when i like your case, at first day using miui 11 stable eu, i can get 2days with 6h sot, most of it using wifi. Then i setup my phone completely. On next day, the battery getting drain fast, and it cant last for 1 day, and just 5h sot. Next i check battery usage, and whatsapp at the top rank. And i unlocking every task. The next day my battery back to normal. And when im writing this post, my battery have 85%, 2h sot, and 7h ago since last charge.

Miui 10 with airplane mode enabled

Since I upgraded to MIUI 11 the battery drains fast

not much draining for me but never go deep sleep, most used frequency is 576 mhz

Hi everyone,
I have the same sad issue.... changed from a 3 years old Redmi Note 4 to a 9 lite.
Battery life with my old Note 4 (same 4000mah) was twice the battery life on my 9 lite, after 3 years!!
I disabled everything in 9 lite, NFC, wifi, bluetooth, background and startup apps, animations, notifications, Gplay updates, face unlocking, always on display, enabled dark theme etc etc....
Same battery drain, 12-13% Android System usage on battery stats.
I hope it will be fixed on a newer MIUI update, but it is very irritating to have to charge a new phone every day, when on an older you had a double battery life.
Please update us in case we'll found a workaround....
Just a question.... How do you monitor CPU usage? I see the setting inside developer options has been removed.....

Same here. Tried many things. Looks like "Settings -> Battery and performance -> Battery saver" solved problem for me. Used to drain ~30% over night while idle, now ~7% in same case.

I suppose battery saving tries to shutdown functions I already disabled...
I tried to leave a feedback to Xiaomi.
Also I created android commands local file dump with code *#*#284#*#* and trying to investigate by myself...

I tried modify modify some settings and uninstall or disable some not used apps before. It made almost any difference.
Previously I used Samsung smartphone. With similar settings I had great battery life. It seems mi 9 lite just cannot sleep/deep sleep without Battery saver turned on. I did not notice any difference in performance, user experience or notification frequency while this setting is on, and it seems it works in different way compared to Samsung implementation. Just give it a try.

May be I'm out ; when I sleep if my screen is " up " I lost 25- 30 % of battery : ( when my screen is "return" 4 or 5 % : )

With my 3 years old (after 3 years...) Xiaomi Redmi Note 4, I assure you, battery life was at least triple of my new 9 lite...

Interesting.... I'll try....

I find it crazy how this phones loses 7-10% overnight while my RN5 lost maybe 2. I work and live in area with bad 4G but decent 3G signal. I try to force 3G when I can.
I just switched on battery saver to see if it helps my standby drain at all.
I'm currently at 1.5 days off the charger, with 37% battery left after 4 hours of screen time. I am a fairly light user and just browse Reddit, XDA, text, hangouts, and 2 email accounts. Reminds me of my Nexus 5 lol. So terrible considering I do so many things to try to squeeze as much battery life as I can.
Maybe my Galaxy Watch being constantly connected has something to do with it.
Top 4 battery users are :
Android system 20%
Phone Idle 12.7%
Cell standby 12.5%
Screen 9.8%

Have you tried a GSI? Does anything stop working, like finger print reader, etc?

Inserting code ##4636#*#* and accessing networks menu, I found that in both SIM1 and SIM2 is set as default (LTE/TD-SCDMA/UMTS if you have 2 SIM and you use Dual 4G, LTE/TD-SCDMA/UMTS on SIM1 and TD-SCDMA/UMTS if you have 2 SIM and don't you use Dual 4G as default), the chinese network TD-SCDMA (before or after LTE network)
Probably this cause waste of time, battery loss and an higher sar level, mostly when LTE network coverage is not at its best.
Unfortunately this setting can be modified inside this menu (setting for example LTE/WCDMA), but this is lot when you restart the phone.
My firmware version is PFCEUXM european Rom.
I wish this TD-SCDMA chinese network will be definitively removed in next rom upgrade!!!

Poor battery life on second P30Pro

Hello, I had p30pro and was perfectly satisfied with it but from curiousity changed it for oneplus 7 pro and then galaxy note 10+, wasn't satisfied with those devices because of worse battery life than p30pro, I had 8-10h screen on time with p30pro and ~5h with one plus 7 pro and galaxy note 10+. (gsmarena endurance rating is not correct, p30pro according to them has 100h endurance rating and galaxy note10+ has 107h, so I expected battery life to be pretty much the same but its far from that )
because of magnificent battery life on p30pro i changed back to p30pro, but this is second unit I got and battery life is not like on the first one. first one was 1 year old 8/128, current one is 8/256 3 months old and I have like 5-6 hours screen on time with new one which does not satisfy me, battery life is primary reason i got back on p30pro.
usage is the same, same applications installed as far as i am aware
I have screenshot from first p30pro with 8hours screen on time and 25% battery left, it was so great that I had to save it :laugh: and battery life was contant like that
Other pictures attached is from current device, 3h31min screen on time with 38% battery left, so by the time it drops to 25% like screenshot from first p30pro it would be like 4h30min screen on time, big difference. battery life is constant like that
any tips, solutions, suggestions, thoughts?
-i did wipe the cache in recovery
-i tried dark mode
-no app seem to be draining the battery
solutions that i am thinking about:
-wait for 10.1 update for my device and see if there is any changes
-sell this one and get third p30pro (really dont want to do that, I will lose money and time and would be furious if i dont get good battery like on first device )
-factory reset (really dont want to do that, I will lose half a day again customizing and installing everything)
is integrated battery info correct, could there be something /an app that drains the battery but is not showing correctly in battery usage?
FAULTY UNIT?

There must be somethnig draining battery , either delete one by one apk and see if it improved, then you will know which apk was trouble, or hard reset and manually reinstall all apks, do not use backup as faulty apk will do same harm.
Second phone was new or second hand? If second hand you should do hard reset first.., tip for future..

one thing I noticed on screenshot from first device is that I was using only one sim card back then, I turned off second one now and will see if battery improves, altough in Screen On Time thread I see people have 8-10 screen on time regularly with two mobile signals.
"there must be something draining the battery..." can there be anything like that but not showing in battery usage correctly? because everyhing in battery usage seems fine.
both phones was second hand and I did reset them, but from menu, dont know if there is any difference in reseting from recovery?

1. EMUI 10.1 have same battery in some cases may be worse battery than EMU 10
2. Why sell phone if this one is good just need find what eat battery
3. Factory reset thats in many cases fix drain problem but if you wont do that why you not do backup first than make factory reset
Solution
1. Try put all apps in sleep mode settings ---> battery ---> startup apps (there enable sleep mode on all apps only leave apps from where you want get notifications)
2. Dark mode i recommend you use it any time its not save your battery too much but it can help to save battery
3. Use Huawei optimizer app to clean junks and optimize phone
4. Disable synchronizatios
5. Disable GPS, NFC, Bluetooth if you not use it (if you use any navigation than just use GPS when you not need it)
6. I see your Google Chrome use too much battery use instead Kiwi Browser
7. Same about Instagram use light version of instagram or try InstaMod app its better for me
8. Your screen display use 24+ % battery try lower light i have set on AUTO BRIGHTNESS (Tips in settings display set lower resolution)
9. Cell standby try disable mobile data when you not need and btw try put sim in another slot
10. Disable or Uninstall all apps from Google i have disabled Google Movies, Google Music, Google Drive and mayn other apps just disable all apps which you not use
11. I see you are on stock launcher you can try Nova Launcher or Evie Launcher or Microsoft Launcher....(Tips Evie Launcher is one of the lighweight launcher and build for performance/battery i now use Microsoft Launcher which is same as Evie but with little more functions
If you need any info just ask

so I disabled second sim card yesterday and this is result I have now, much better! 1h16min screen on time with 86% battery, which corresponds with about 8h screen on time :good:
can't believe another sim card has so much impact on battery life. my signal is full!
in next few days I will try only 3g or 2g enabled instead of 4g for second sim card to see if that makes a difference.

5 hours & 40% still left, always using data connection. Mainly browsing and watching videos.
VOG_L29D EMUI 10.1.0.126, firmware updated using hisuite proxy

But also any other firmware version was giving the. Same SOT

Yes brightness is always automatic (indoor and outdoor) , i rarely use wifi,
Usage, facebook, YouTube and emailing, and some light gaming.
Also I'm using two sim cards but disabled 4g on the first sim card wich i use in calls and left the data line 4g.

I think I found your cause of drain. Go to settings, apps, apps, on the top right click on show system apps, then check for hms core. Click that, then on the top right you will se a gear. Click on the gear and carefully untick everything that has to do with data sharing, analytics etc. Check your battery again and let me know mate ??

"Poor" battery life on a brand-new S20 FE (Android 12)?

Hi everyone,
I got my new S20 FE just a few days ago, and I'm still getting used to it, but I wonder if having to charge the battery every day on average is "normal" or not.
When I plug the phone into the charger, the battery is never flat. Rather, it's hovering at around 30%, and I usually stop charging when it reaches 85 to 90%. I use the 15W (?) charger that was in the box, so no ultra-quick charge for this one.
I tried to plug it into a Xiaomi/Poco 33W charger for a few minutes, just to see if it would speed things up, but the remaining charging time was the same as with the regular charger so I reverted to it, just to be on the safe side.
Still, I wonder if it's normal to have to recharge the phone every day, when my Poco X3 Pro needed to be charged every two days on average. Granted, the Poco has a bigger battery, but it has an LCD screen instead of an AMOLED.
I spend a lot of time on Twitter, especially in the evening, mostly, but that's it. No gaming of any kind.
What say you?

Hi,
I've turned Auto brightness off. I'll tell you if it changes anything in terms of battery life. I've also set AOD to fixed brightness instead of auto.
Thanks for the tip!

No problem, thank you for the question!

I think that debloating is not a bad idea, also try to go to all individual apps settings and set the battery to Restricted, except mail and messaging apps, so they won't drain the battery when you're not using them. Lowering the screen refresh rate also helps a bit, as well as restricting mobile data to 4G only, if you don't need 5G. Also, you can limit processor speed, turn Adaptive battery on and Enhanced processing off.

Hi again!
I've changed network settings to 4G and below since my SIM doesn't give me access to 5G yet, but battery life was still iffy. I then changed the network settings to something called "GLOBAL", and it's a bit better, though I don't know what that setting does exactly.

It also depends on how much your using your phone, what apps your running (games vs non-games, etc).
For example, I've played some games, but mainly have been on the internet via apps like social media, email, web browser.
I'm currently at 55% And it's been over 24 hours since I last fully charged it. The Battery graph says based on how I've been using the phone that I still have about 1d 3h left.
I do usually charge once a day, but it's definitely more than 24 hours after the last charge. I went to bed last night with over 62% left after having charged it probably 12 hours prior. When I woke up this morning, it was done to 59% and since then, is now at 55%.
So I've been pretty pleased with the battery life for me. Whether that's good or bad, I have no idea but it's definitely better than my last phone.

I don't do games on my phone (in fact, I don't do games at all, period), but I think the AOD being set on automatic lighting could have something to do with my relatively poor battery life. I'll try to set it to a fixed brightness and see if it changes things, though the brightness scale is pretty rudimentary. Maybe the light sensor is turned off when automatic brightness is off.
I usually spend more time on Twitter when I'm on the phone, so this could explain that.
Another possible factor is my application launcher: I use Microsoft Launcher, which I adore, but every time I wake up the screen, it does a position fix to update the weather widget. That could also explain why my battery drains faster than I expected.
I've just set AOD to fixed brightness. I'll tell you if it helps or not. Thanks for your input anyway!

I used to use Microsoft Launcher, but then switched to Nova launcher. However, since getting this phone, I've moved to OneUI and I'm loving it. I haven't really changed anything. AOD is set to whatever it was out of the box and I've been on Twitter and the web since I last posted and I'm currently at 53%.
I think I have seen MS Launcher be a battery hog if I remember. Nova isn't as bad, but OneUI seems to work great.
Also, the number and type of widgets you have installed could also cause battery drain. For me, I only have one screen. I use smart widgets to "stack" widgets I need which are calendar, weather (from WeatherBug), Brave Search, PowerAmp (for music) and then the phone maintenance widget. So far, battery life is pretty good like I've said.
You can also go into Settings->Battery and Device Care and maybe check in there to see what might be eating up your battery the most.

I like the look and feel of MS Launcher, compared to others (I believe I've tried them all over the years...), even if I have to admit Nova is a close second. MS Launcher is a possible culprit, obviously. I may switch back to One UI to check how things are going, I don't know.
I've just topped-off the battery, and just idling, the phone is supposed to last over 2 days until the next charge, but I know it won't last that long.

So I got my phone used (only 2 months, still has back poly attached) and it came with august 1 update and the battery drain on it is abysmal. I can see the battery go down while I'm browsing insta or whatever, not even gaming. You know what instantly fixed it? Downclocking my gpu and cpu using FKM. But this is not a pretty solution as it requires root and I would like to experience stock without root for a bit.
Which makes me think the system isn't properly downclocking the soc when idle leading to increased drain. I would like to know if anyone has a better fix than just disabling all the options on your phone.

Well, considering it's used (was it refurbished or did you purchase it off eBay or some other market)? That might be why it was being sold. You said 2 months. Does that mean it was only used for 2 months or you've had it for 2 months? If the phone itself is only 2 months old, who knows how the previous owner used the phone.
Did you do a factory reset when you got it to ensure it was back to stock settings? If so, then it might be your battery is bad and could be the reason it was sold/returned by the previous owner. If you haven't factory reset it, that is possibly the only other option that I can think of if you've already rooted and downclocked it.
Mine was new when I got it a few weeks ago and the battery lasts 1.5 days for me, even with the refresh rate set to 120 Hz. And that's with moderate use (playing games a bit, browsing the web, texting, phone calls).
You might want to try setting your screen refresh to 60 Hz to see if that helps as well if you haven't done that yet.
Go to Settings->Display->Motion Smoothness and select "Standard" to set it to 60 Hz refresh. That will save some battery as well.
See if that helps as well. If not, and as I stated, if you haven't done a factory reset, that might be your only other option unless someone else has something I haven't thought of.

Did you do a factory reset when you got it to ensure it was back to stock settings? If so, then it might be your battery is bad and could be the reason it was sold/returned by the previous owner. If you haven't factory reset it, that is possibly the only other option that I can think of if you've already rooted and downclocked it.
Mine was new when I got it a few weeks ago and the battery lasts 1.5 days for me, even with the refresh rate set to 120 Hz. And that's with moderate use (playing games a bit, browsing the web, texting, phone calls).
You might want to try setting your screen refresh to 60 Hz to see if that helps as well if you haven't done that yet.
Go to Settings->Display->Motion Smoothness and select "Standard" to set it to 60 Hz refresh. That will save some battery as well.
See if that helps as well. If not, and as I stated, if you haven't done a factory reset, that might be your only other option unless someone else has something I haven't thought of.

Yeah I got it from a store second hand. Came with the back poly still attached and no damages on the body. A killer deal. As for the battery issue, I had flashed wrong region stock rom. After learning what csc meant and figuring out I was on the wrong region I flashed the right rom and now my battery life is top notch. On a side note it has only 54 charge cycles after I got it.

Glad you were able to figure it out. Even though the phone is reaching 2 years since it's release, I've been very happy with it. My S7 finally died over a week ago after 5+ years of dependable service.

This is actually the second device I bought this year. At first I upgraded my Redmi Note 5 Pro which gave me 4 years of great service. Could have reached 5 but then I would not be able to exchange it so I did and got a Redmi Note 11 Pro Plus 5g. Considering how much I paid for it I was more or less satisfied except the camera. Then I bought this after months of careful consideration and also because it was a killer deal. I got a brand new device for half the price. Flagship specs at 33k bdt. You can't get a better deal.

Question Critical battery drain

Hello
Yesterday i had the phone around 65% at 01h00, in the next morning (around 7h20) i wake up to find the phone at 1%, no wifi/4G/bluetooth/GPS...etc was active, even the battery saver was ON. As you can see in the screenshots, android system drain battery around 400% !!! what's up with this behavior ? happened the 1st time last week (49% drained in 8 hours) the problem seems gone after i fully charge and than reboot, but still today happened.
The phone is almost 1 month old.
The 1st few days, i disconnected the phone from charging at 100% and went to sleep, after 6 hours battery is drained by 6% without doing nothing. is this normal ??? screenshot
ROM : crDroid 8, latest magisk installed+microg+magiskhide props config and fdroid/aurora modules installed.
Thanks

clearly something is going wrong, I would suggest factory resetting, and optionally reinstalling your custom rom.

well, that must a bug related to optimiztion of the rom, report it to the rom mantainer

Exactly what happened to me same ROM same phone but I didn't root it. it drained from 54% to 6% during the night, next day I switched the ambient display off and the battery became better but so far I am also looking for solutions to make it similar to miui
I feel the battery is draining so much fast when I start using the apps unlike miui but the room is also great and fast , with my light use it gave me 1 day of use and remaining of 10% with 120 fps (3.3%/hr screen on and 0.6%/h screen off )
today I will test it with 60fps

No, only when charging of course (around 40°)

I'll wait and see if this bug happens again as right now i need the phone for the rest of the week, if happens again i might switch rom altogether on the weekend.

Wow, 3.3%/hr is seriously impressive for active drain, especially for 120hz. Can I ask you if you did anything special / your exact setup? I installed Ricedroid 8.0 + Sleepy kernel and applied the GMS Doze module + Naptime (as suggested by a kind poster on here), and this allowed my idle drain to go down to 0.2%/hr, but my active drain is still struggling a bit.

to be honest I am not sure if I report it correctly I have used accubattry app but I will post few screenshots from the app and you can see , I didn't do anything except disable the ambient display maybe my usage is light in default I don't know I also formatted the phone like 20 times during my testing for different ROMs. I found Cr-droid to be the best so far or miui

Ohh the 3.3%/hr is combined use, which takes account of both active drain and idle drain (through what I guess is some weighted average). But honestly, 6.7%/hr (or even 7.8%/hr tbh) is still pretty damn impressive, so I'll thank you for letting me know! Now I wanna flash crDroid haha.

I spent 1 day and half trying all custom roms in this forum because for long time I was on miui and didn't know how custom ROMs are now , after trying I found that all custom ROMs either are pixel flavored or very basic without any customization and I settled with Cr-droid because it offers best of both worlds less google and good customization options.
now regarding the battery after few days of using on 60 fps I have combined use 2.4%/hr and 0.8% screen off but I still feel that it drains fast during my usage compared to Miui , I have only used naptime for optimization do you advise me to add anything else for non-rooted device ?

MIUI very often switches off alarm (not clock alarm) and wakeups -- it's known for long. Your notifications often comes late when using MIUI. In real life situation, however you might never notice it, but it's there. It also sets higher priorities to known messaging, social media apps to receive notification/action faster than any apps that are outside "the list".
It's a good trade off for battery life compares to stock AOSP or lineage which put every apps on generic list of "optimized battery" based on your pattern. It will took a long before the pattern is useable.

I'm not sure about your possibilities on a non-rooted device honestly. I think Naptime can work on a non-rooted device, if you grant a few permissions through ADB first (if I remember correctly, the app itself will guide you through the process). Be mindful of which apps you're restricting though, as Naptime will likely cause delays in the arrival of notifications. You can whitelist apps through Android's battery restriction screen.

yes I am it currently after activation via ADB it made some improvement I felt , so far the highest consuming system apps are : Android OS [19%] screen [9%] and System UI [6%] can I do something about them ?

Hmm I don't have any further tips honestly, not about these specific things. In my case, using Naptime already improves battery life by a ton over the course of a day (not wasting entire %s in hours of idle time is already huge).

Try and see if greenify or its replacements helps.
