Hello guys, here are my results if anyone needs it.

Getting 7 hours of screen on time (13 hours since removed from charger) comfortably with moderate usage, no games, mostly browsing, some YouTube and social apps and making some pictures.

It was 6 hours of mobile data (part of it in metro with bad coverage) and the rest is with wifi.

It seems to be sufficient for a whole days use.

I am satisfied with it.
[Xiaomi Mi 9 SE Real Life Review] maikel2201:
WOW this looks great!

what version are you on? global, eu, china or Russia? and what update?
[Xiaomi Mi 9 SE Real Life Review] kenny59:
I am on Global 10.2.5.0 (PFBEUXM), stable

Oh and I forgot, bluetooth was on all along, connected to mi band 3. Not sure how much it affects the battery though
[Xiaomi Mi 9 SE Real Life Review] Harrison8c:
Yeah I had these >7h SOT but most realistic is 5h per 24hours without gaming. My SD625 LCD phone after 2.5years still had a better battery than this one.
[Xiaomi Mi 9 SE Real Life Review] fattymcdirty:
Pretty impressive.
[Xiaomi Mi 9 SE Real Life Review] morgs640:
The Snapdragon 625 was a legendary CPU battery wise.
[Xiaomi Mi 9 SE Real Life Review] Humpfrey:
Hi, i don't know how you get these SOT.

My SOT, most likely without WiFi, no games even installed. just a few pictures, maps and WhatsApp.

I'm on global stable 10.2.5.0. so far, not impressed nor very satisfied..

Cheers

My SOT has also been up an down. One day was around 5-6 hours. The next with some bluetooth, GPS, whatsapp, phone calls etc was 2-3 hours. On stable global ROM 10.2.5.0
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
Did you try with the dark mode? It should helps

Running 9.5.16 beta
[Xiaomi Mi 9 SE Real Life Review] G_4_B:
ROM used? Any particular settings for that SoT? Thanks
[Xiaomi Mi 9 SE Real Life Review] denzel09:
9.5.16
[Xiaomi Mi 9 SE Real Life Review] G_4_B:
I buyed MI 9 SE yesterday.

I'm thinking to unlock bootloader and flash xiaomi.eu (have it on my old 4X)

The stable is much worse then weekly? I prefer to not upgrade every week...
[Xiaomi Mi 9 SE Real Life Review] Harrison8c:
No they're essentially the same but weekly has risks of unknown newly introduced bugs. Don't upgrade every week then. I use weekly because at the time I want the latest features and I update like once in a year when there are features that I want to have.
[Xiaomi Mi 9 SE Real Life Review] checo79:
for mi 9 se???

where do you find?
[Xiaomi Mi 9 SE Real Life Review] G_4_B:
Thanks.

I'm interested in a good SoT, so if there isn't much difference in that aspect I flash stable xiaomi.eu (the global EEA have a worst SoT)
[Xiaomi Mi 9 SE Real Life Review] denzel09:
It's .eu version i think
[Xiaomi Mi 9 SE Real Life Review] PurPLe SKy:
My results are close to yours. Yesterday I pushed it quite a bit, been out in the sun in the morning (with auto brightness), did a little use of maps, whatsapp, telegram, a little bit of browsing and few photos. After supper I was at 30% with 2 hours of SoT. Yes the battery is very small but I was hoping for better results. The feeling is that the phone isn't optimized at all., my 6P did better with that failed CPU that was SD810 and a slightly larger battery. I'm on 10.2.2.0 PFBMIXM.
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
You should try another rom
[Xiaomi Mi 9 SE Real Life Review] PurPLe SKy:
From what I read there aren't significant differences between EEA and MI firmwares. And I would like to keep the global one right now.
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
At least on my device I see a difference

2 days of standby and 4.35hrs SoT
[Xiaomi Mi 9 SE Real Life Review] PurPLe SKy:
I'll wait the next update to see if it gets any better, then I decide if changing it with another phone or keep it despite the undersized battery life.
[Xiaomi Mi 9 SE Real Life Review] xXPhoenixXx:
That's some impressive battery life there. Mine is nowhere near, which is why I'd like to ask some question if you don't mind,

1. Do you use any "optimisation" Magisk module?

2. Where do you live and do you have custom network type set? (LTE/WCDMA, etc)

3. Do you use battery saver? (battery saver mode/adaptive battery)

4. Which ROM and Kernel are you using exactly? I'm using the latest stable Xiaomi.eu with Okitakernel V2.0, which helps with the battery life but it's still not optimal

5. Do you use any noteworthy battery saver method? Eg. a Magisk module, a custom setting somewhere, anything

6. Do you use AOD? Do you have auto-brightness enabled?

7. Finally, what is you 'Cell standby' and 'Phone idle' drain? I'm looking at the battery stats now and I have 2h 25m screen on time, which counts as 10.6% on the power usage screen, while Cell standby is following with a baffling 9.3%, followed by Phone idle with 7.5%. I'm mostly connected to Wi-Fi, using some messenger apps like Telegram and WhatsApp, so I don't expect 0 idle consumption, but Cell standby almost matching 2.5h of screen on time in terms of power drain is something I can't accept.

Sorry about all these questions but you'd really help me out if you provided this info and anything else that comes to your mind! Thanks a bunch!:)
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
Check my answers in red. Im not sure what is the problem. With the stable one you should get a decent battery time.

Global. One round im fortnite, watching YouTube and reading forum. Everything on dark themes etc. I don't have xiaomi account and don't use apps from xiaomi. synchronization only with google. I changed one option in the system itself. Searching for network signal - LTE / WCDMA search
[Xiaomi Mi 9 SE Real Life Review] xXPhoenixXx:
Thanks a lot! I managed to find the culprit. My email client (bluemail) had some buggy push setup where instead of push it was fetching real time, generating background activity and preventing the phone from going into deep sleep. My battery life is still not as good as yours but I reckon I will wait and get MIUI 11 instead of getting obsessed with all this optimization business.

Also, thanks to everyone else for sharing your SOT!
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
Im now trying the lastest beta without custom kernel and the consumption is higher than before.

I think Im going back to my last setup
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
I guess I was wrong.

This is what I got with the new beta (9.6.13)

2 days and 5:40hrs SOT . BT always on, no power safe mode and mostly WiFi use
[Xiaomi Mi 9 SE Real Life Review] sxxorp:
Testing battery life without 4G

As I read some suggestions that weakly optimized 4G can ruin battery life I did a test without it: 6hr SOT in 2+ days -67% of battery.
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
Thats great!

So basically running wifi all day plus mobile off?
[Xiaomi Mi 9 SE Real Life Review] sxxorp:
That would mean that it's not really a phone anymore :) No: I made most of available setting optimizations (no root), dark mode everywhere, Kiwi Browser, Greenify, Adguard Beta program, most of redundant Google apps disabled, etc. I'm in airplane mode only during sleeping, otherwise Mobile Networks are set 3G Preferred, but they are on (4G might be set on those rare occasions when WiFi isn't available).
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
I guess the most important thing there is the airplane mode, but hey its a good one
[Xiaomi Mi 9 SE Real Life Review] sxxorp:
I have always used airplane during the night (in MIUI 8 it was a perfect automated task...) that's not the difference, but 3G Preferred instead of LTE/4G Preferred.
[Xiaomi Mi 9 SE Real Life Review] xXPhoenixXx:
Amazing battery life guys, also, in case you haven't noticed there is an updated(v2.5) version of Okitakernel which claims better battery life. I just flashed it, looking forward to see how many hours I can squeeze out of it. Thank you for the hard work [MENTION=7190920]yuneharuka[/MENTION]!
[Xiaomi Mi 9 SE Real Life Review] maikel2201:
give us an update after your tests, please
[Xiaomi Mi 9 SE Real Life Review] xXPhoenixXx:
I've put the phone in airplane mode for the night(about 8h 30m sleep) with wi-fi turned on and nothing else, no bluetooth, no nfc no nothing and I lost 7% of battery. Something doesn't add up. I'll keep testing.
[Xiaomi Mi 9 SE Real Life Review] spix123:
With fingerprint enabled (and always show setting enabled) there doesn't seem to be any way to avoid ~1% per hour standby drain.
[Xiaomi Mi 9 SE Real Life Review] xXPhoenixXx:
I heard problems about 'always show fingerprint', but just by having fingerprint enabled I haven't had any problems. About 5% a night was normal before (no airplane mode).
[Xiaomi Mi 9 SE Real Life Review] okitavera:
For the record, the qcacld module are loaded from the vendor partition, not from the kernel itself.

So for now, that kernel don't have any tweaks for the wi-fi departments. Sorry.
[Xiaomi Mi 9 SE Real Life Review] xXPhoenixXx:
Seems to be behaving normally now. During the night, the "Phone idle" consumption was massive. It's usually the "Cell Standby" that I have problems with. Right now, both are showing normal values. Airplane mode must have triggered something.

Battery drain

Hello everyone - I'm new here.

I have a problem with my mi 9 se, what it is "Google" aplication?

I don't know why it drain battery so much...

Do you know what to do ?

:(

---------- Post added at 01:55 PM ---------- Previous post was at 01:40 PM ----------

I disconnected mi 9 se from the charger in the morning.

Right now 45% SOC

1h 20 min on screen

The "Google" app is on the first place of battery usage, it consumed 38%.

Please tell me why ?
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
I got 7hrs SOT with revolution os rom and okita kernel
[Xiaomi Mi 9 SE Real Life Review] sxxorp:
Huh, my average is better on 10.3.1 Global stable without any fuss... I attached one of the best, only 2/3 battery is used to preserve its life. Just imagine if I had used it -21% like you to 12 AND I even had 1d17h of usage, +10h to contain more taxing idle time.
[Xiaomi Mi 9 SE Real Life Review] kris12151:
10.3.4 global stable, i reach everytime 5h SoT. No facebook and messenger app (using friendly, force closing after looking on new feeds), no insta, twitter etc., Just whatsapp on and gmail. No fingerprint unlocking. Signal settings changed to lte/wcdma.

Imo its pretty decent SoT. And with quick charge, the 3000maH isnt annoying at all, 5-20 minutes of charging is deal.
[Xiaomi Mi 9 SE Real Life Review] akiroJo:
I definitely agree.. getting almost 13hrs SOT, on mixed use in HM5Plus(vince), no gaming.

I am rooting for Mi9SE this year, probably the main selling point is its compact size, regardless of all the missing features I got used to, like audiojack, fm radio, notification LED etc.

Something must be using up your battery. Might be miui or some apps. Use a battery app to find out where it's going. I don't have much running in the background.
[Xiaomi Mi 9 SE Real Life Review] eeemmmbiz:
I've tried every custom rom for the mi 9 se and the most I've gotten is 6-7 hours SOT, until now. I just flashed the MIUI EU weekly rom (MIUI 11 based off Android 10) and I'm getting 10 hours SOT. I've included pictures in this post with the miui version and the battery stats. As you can see from 100% to 50% I got a little more than 5 hours SOT.

With the current lockdown, I installed the Bliss Rom, was on xiaomi.eu before it, and I gained a lot in battery life.

When before within 2-3 days I achieved something like 5-6h of SOT, I get 8-9h with the same apps, same usage.

Within 2 days cycle with VoWifi on and airplane mode on, I get more than 10h, really impressive this custom Rom.

And the most important, we get rid of all the bloatware from Xiaomi, even with uninstalling the maximum of apps with root.
[Xiaomi Mi 9 SE Real Life Review] rp158:
Can confirm this. I get on LOS 17.1, developed by [MENTION=3783116]pengus77[/MENTION] too, 10-15h SOT /2d. All due his efforts of optimizing Kowalski-kernel, vendor and system.

[Xiaomi Mi 9 SE Real Life Review] e_henning:
Does Bliss Rom include vendor and baseband.

I don't have telegram but I really would like to try this because it is offical and seems to be well supported. I prefer Roms that include vendor and everything. Can Somebody tell me if Bliss Rom includes it so I can perform a full wipe and clean install.

I would apreciate if someone could post a short installation guide that includes all steps. I am currently on Revolution OS newest version but it seems kind of buggy to me even though I liked the previous versions a lot.

Sorry for misusing this thread.

Thanks for help or pointing me in the right direction.

Hello forum, my SOT is awful for me.

Im not getting more than 3 Hours of screen on time

i am using Miui 12 Global Stable

i have the phone from year and a half and i never used it on Wi-Fi (because i have unlimited data)

Data is 24/7 on

AOD is ON

Listening 2hours youtube on background with bluetooth headset but not every day

Sync & GPS is on (Sync because of a email and GPS in casd my phone got lost or stolen

Is there any way i can get 7-8 hours of SOT like you guys?

Thats my apps and usage

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Xiaomi Mi 9 SE's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

Then, drop a comment if you have anything to add!
[Xiaomi Mi 9 SE Real Life Review] nevusZ:
There is one setting that influences standby battery drain very much - "mobile signal standby"

Have a look in your battery monitor.

I have got Mi9SE Global V10.2.5.0.PFBEUXM and my battery lasts longer now.

Go to Settings -> My Device -> internal storage (click 4 times until you are in test suite)

no go to telephone information 1 or 2 (according to your sim)

look for "set preferred network type"

default value is - LTE/TD-SCDMA/UMTS

but in europe there is no TD-SCDMA - so the phone searches for a mobile network that does not exist. this drains your battery

set it to LTE/WCDMA

enjoy much longer battery!

ATTENTION - after a reboot the setting is back to stock! you have to set it again or wait for xiaomi to fix it in a future release!
[Xiaomi Mi 9 SE Real Life Review] checo79:

I got Mi 9 se like 2 days ago and I already had read this post, so as soon as I got my phone, I switched to wcdma only as I only use 3g.. The battery life coming from SD 625, 4000mA was underwhelming but still got 7 hours out of it, 1 day and 2 nights usage to the max.. The thing thats bothering me is the cell standby time! It's eating away the battery in idle and during screen on.. Got 8 percent battery drain during the night with everything off and it's been the highest consumer till the end (screen time just took over it at the end).. I am on 10.2.2.. Apparently there is no help regarding this anywhere
[Xiaomi Mi 9 SE Real Life Review] ChocoHR:
You should try the 9.5.16.

[Xiaomi Mi 9 SE Real Life Review] pengus77:
Hi there, just made a quick test overnight and I "think" I found the root cause. I deleted the fingerprint data thus disabling the fingerprint reader and the results are a bit worrying... got 3% loss in 7 hours during the night. This morning I'm stable on 1% / hour drain with short calls and AOD on. I'll take a look in the kernel if I can find anything related to the reader power management, but I'm pretty confident the cause is in there...
[Xiaomi Mi 9 SE Real Life Review] christiantanjung00:
i dont think so bro, i'm not use fingerprint security and aod. but i wonder why android system spend bigger battery drain than the gaming apps, it was more than a half difference power usage. r u have other advice bro?
[Xiaomi Mi 9 SE Real Life Review] denzel09:
I see Cell Standby consumption really high, always at least 25% of battery. No changes with different sim, i tried all :eek:
[Xiaomi Mi 9 SE Real Life Review] spix123:
Mi9 SE standby is bad, even with no sim card. Drains 2x faster than mi5 even though mi5 battery is old and only has 2000mah capacity left. Mi9 SE in theory should be more power efficient due to newer cpu. Something is going on here.
[Xiaomi Mi 9 SE Real Life Review] spix123:
I'll let my phone standby for 2 days with fingerprint enabled, then disable fingerprint and let it for another 2 days standby to see if it will confirm your suspicion. I also thought the fingerprint might be causing standby drain as its new tech so could be unoptimized.
[Xiaomi Mi 9 SE Real Life Review] pengus77:
Sounds good to me. At the moment I'm at 77% after 7.5 hours of medium usage. 1 hour SOT, about 30 minutes calls, whatsapp web connected all the time and some background apps (telegram, bank app, gmail, calendar, etc). Connected to wifi 80% of the time, 20% in LTE with VolTe enabled. Also, AoD always on.
[Xiaomi Mi 9 SE Real Life Review] spix123:
That doesn't seem too bad but its hard to pinpoint standby issues when the phone is being used normally, even though it is still stealing your battery at a steady rate during the day. For example if standby performance was similar to other devices, you could expect to have 80-81% left now. Mi9 se is draining at least 1% per hour (airplane mode on,wifi on, fingerprint on, aod off) and other phones I have are at most 1% every 2 hours (some 1% every 3-4 hours) with the same settings. It all ads up during the course of the day and can be the difference between a single charge being enough for a day or not, and it gets even worse for light users who usually go a few days without charging, it wouldn't be possible with mi9 se due to the standby drain. Hopefully its fixed in future roms, 10.3 has been released in China almost a month ago, don't get whats the holdup for global users.
[Xiaomi Mi 9 SE Real Life Review] spix123:
I just completed same test on Redmi Note 5, both phones on latest MIUI 10 global stable.

Mi9SE 100-0% Standby time 4 days, 3000mah

Note5 100-0% Standby time 14 days, 4000mah

All same apps, all same settings, I made sure everything was equal.

Note 5 standby time is 350% but battery only 30% bigger.
[Xiaomi Mi 9 SE Real Life Review] pengus77:
Aye, it's problematic to check when using the phone all day, i agree.

About the chinese rom, I'm using the latest xiaomi.eu dev rom which is based on the china dev channel. It's actually the latest code they released and the drain is still noticeable. With this phone there are some issues, probably the baseband firmware is not really optimized or they changed the polling time in the telephony framework or whatever else. Without sources I'm not going to decompile half the rom to find out what they did... but I can at least look in the kernel and check if the modules PM is "done right". I also have a feeling that CAF is way ahead compared to the kernel they shipped and probably Qualcomm already pushed a load of patches for the 712 while xiaomi uses an initial kernel for this cpu. This will take a bit of time but I'm curious :)
[Xiaomi Mi 9 SE Real Life Review] djtinxo:
You can see it especially when checking the graphic of battery consumption. It never is flat when in standby. I only have got these even graphics a couple times and I can't figure what the scenario was like.
