Battery life discussion - Asus ZenFone 3 Guides, News, & Discussion

Would like to know what battery life you guys are getting. A relative bought one and his battery life is really quite impressive, much better than his previous phone, the LG G2, which by all accounts has solid endurance.

I've only had the Z3 (ZE552KL model) for a few days but the battery life is absolutely stunning so far. I am *so* pleased with this phone.

Amazing battery life
The battery life is a thousand times better then my previous phone s6

Very Good so far. Only been 3 days
Quite pleased with the battery life so far and the phone overall except for a few nit picks on the annoying Asus software and bright settings screen. Was hoping that with USB-C it would have a quick charge type of thing going but I find it seems to take about the same time as my Nexus 5.
Probably not as good as the iPhone 6s and above but close in my opinion. Excellent phone so far. Does not compare to the Oukitel K6000 Pro with a 6000mah, that phone is a beast though and unfortunately useless for most carriers. Hopefully this battery lasts as well as my Nexus 5 has for almost 3 years.

I directly upgraded my ze520kl to nougat when buying and it's still have quite impressive battery life. I could get 4 to 5 hours of SoT including playing games for around 1 hour.

I'm so pleased with this phone battery life. Receive many updates too (at least 4 from the day i bough it). It's better after updating.

I think battery life has been decreasing since the first days. So I start to look for tips on this and others forums.
So I find this: Just disable everything you can from Mobile Manager and make Dozer from Android make their job.
Now I have incredible standby performance, very close to 0% for hour.

Whitout games I could take more than 9 hours. But happens only that time. I had something between 6-7 hours SoT in a casual day.
But I had disable Mobile Manager these days and I could get more time without a charge than never.

I am stuck between the LG G2 and the Nexus 5. I will buy the phone unlocked. Both are priced the same in my country. I've been to multiple stores and tried the devices.
I really like the nexus 5 but the battery life is main concern.
My daily usage is somewhat like this:
2 hours of offline music (screen off).
30-60 minutes of web browsing
10 minutes of phone calls
30-40 minutes spent on apps like feedly and 9gag and other such apps
Average amount of messaging
Don't click a lot of pictures (1-3 in a day or even none)
Average amount of messaging
Most of the day is spent on wifi
Network signal strength is good. No LTE in my country so I use 3G
Little to no gaming on the phone (1 hour cumulatively in 3-4 days, mostly 2D games)
So can I get about 13-16 hours with this kind of usage? Will android lollipop make things better?
Or should I go for the G2. I know that the battery life is much better. But Personally I don't like the user interface on the G2. Plus I've heard that the bootloader is locked on the G2. I know about the Loki bypass but it has been patched up in the 4.4.2 update so I don't know whether I'll be able to flash a custom rom on the G2. Also I've heard that developers are now reluctant to develop for the G2 because of this?
So please suggest what should I buy. Should I get the nexus 5?
G2 will get lollipop update .... That will change ui to that of g3. ...
Also since ur usage is above moderate ... G2 will be better..... my choice would be g2 it suits ur need better
G2 = bigger battery
N5 = updates
And as said above it will get the g3 ui but i heard somewhere that it apparently lags a lot...
That would be it
I don't think anyone can or should decide which phone you should buy. Looking at your list I think it should best for you to decide what you want most from your phone.
I personally have to charge my N5 once a day, sometime twice depend on the usage.

Than you for your reply, but I figured out that much by reading the spec sheet of the phones. You're stating the obvious. What I really wanted to know is how the nexus performs. Since you are on this thread, I assume that you have a Nexus 5. What I want to know is how does the battery hold up with your usage. Please elaborate on your usage. Will I be able to get a day out of the nexus with my usage?
I really want the nexus, but the battery life is holding me off, if I can get the usage I want, then I will get the phone

I agree that I will be the one finally deciding the phone. But I really value you opinions. They will ultimately help me decide. You say you charge you phone once or twice in a day. What is your usage pattern? How many hours do you get out of a single charge? Can I get the usage I mentioned in my first post out of a single charge?

Again. all of this is subjective. Depends on what all apps you've installed and how you've setup your phone. With your usage pattern, it will be slightly difficult for you to pull this off.
The same usage patterns will differ from person to person as it depends on a lot of variables.

I second this! I'm usually around charger at all times so, battery life doesn't really hurt me much. But, when I know I won't be around a charger, I do carry a powerbank in my backpack!
I am currently running the newest android 5.0 dev preview, and since installing it my battery life has improved drastically. And android 5.0 has a battery saving mode that kicks on at 25,20,15,10, or 5 percent, you choose what percent to set that at. I am a power user to the extreme. I really mean extreme. I have nfc and Bluetooth on all the time, on the web multiple hours per day reading and watching videos, on calls for 1 hour per day. I top off the battery on a wireless charging pad for one hour during lunch, and i leave it on a charging pad overnight. And i get by just fine. But everyones usage will very depending on how you use and set your phone up. I would not let battery life determine my decision if i were you. Look at other features, size, feel, etc. Personally ive had a n5 since launch and i wouldn't trade it for anything at this time.
I had the G2 for a long time. While it was a great phone, with awesome battery life, after now getting a nexus 5 I much prefer this phone even if the battery isn't as good. But its all personal preference. I love this nexus 5.

Sorry i answered to quick. The n5 can give you 2 days if you want but this means that you are on a good kernel (stock or elemental) and on a good rom (stock is the best i think). In this 2 days I dont use data much so the phone is mostly on wifi and i get around 5- 6hrs screen on. I dont dimm the screen i leave it on auto mostly and i have it oveclocked to 2.5. I also cover a lot of browsing in tapatalk, reddit and also in chrome (which became a big batt sucker lately but things are improving). So at least 2hrs in these apps. Also around 20min talk time. All the time i am on 2g with a very good sigbal. My conclusion... It should get you through the day np
Regarding android l people are reporting better battery results
And just to clear it even more. Yesterday i flashed the pa beta 6 build (had enough of L) and left it on the charger through the night. I woke up downloaded a 2gb file via wifi reinstalled a lot of missing apps listened to some music for 30min (i use viperfx which drains the batt even more) and in the end of the day i have a 2hr sot with 12hr standby and 54%. The 2hrs were browsing in bacon, chrome and tapatalk. But this is the first cycle and as you know it needs a bit to settle so battery life gets even better. So in a few days i would expect a 2hr and 30min sot time with the same usage as i had today. This would be it. If you got any more questions just ask
have both these phones in my family... if you get the chance put them side by side.... nexus 5 has a yellow screen
i never notice until i mess with my wife's g2, as my eyes accept the whites on my nexus 5 as normal.

I think the yellow screen can be replaced
Imo kernel has a very less effect on battery life.... It solely depends on your usage, network and display brightness..
The Nexus has a battery results thread in the general section. How about checking that out. There's hundreds of members battery times already there to review. ?

Since you don't have LTE in your country and you don't do intensive gaming, you might want to consider the Moto G 2014. The battery life on the Moto G will be better than the Nexus 5, and unlike the G2 the Moto G is unlockable and the software will be up to date for a good long while. It also doesn't hurt that the G is like half the price of the N5.

3 of my friends have the 2014 Moto G. I've used it and I must say I was impressed. But there are two major shortcomings of the phone. First the barely over 4GB of space for apps. With ART being the default runtime in Lollipop, Apps will only get bigger in size. Second is the 1GB RAM which limits the multitasking to a certain extent. Also I do play intensive games on my phone, on weekends or on my days off when I'm at home, so there's that. More importantly I don't know how the Moto G will hold up over the course of 18-24 months
If someone has no interest in big graphics games, or any CPU intensive activities... And doesn't care about having the "best" phone out there..... The G seems like the best bang for your buck deal out there. ?

Battery Life Discussion

Before purchasing, I was a little concerned about the amount of battery time between charges on the S6. I picked up the phone yesterday and was able to get 4+ hours of Screen On Time (SOT) with my first full charge. I didn't think that was too bad. I think the fact that it is a new device, I tend to "play" with it more in the beginning. I'm hoping it will get better as it settles into my routine. I still am a little concerned though as I didn't even have an hour of talk time to go along with the SOT, didn't stream music, play any games or really use any other apps. It's been quite a while since I've had a smaller sized battery in a phone I've owned so I may be hoping for too much when it comes to battery life. I had the LG G2, Galaxy S5, LG G3 and Note 4 prior to purchasing the the S6. I love the phone and don't plan on switching. I just thought I would get others opinions on it.
Battery life is bad. This is what it predicts for me. I get 15 hours basically with only chat and web browsing. I sleep off the charger and the phone loses 10-12%
Gps and playing music during a drive just gave me 4 hours. I'm trying to break the battery in by bringing it to 5% and recharging, but this is laughable.

Here's what I've got for the day
So far I'm not happy with the battery life. I'm coming from a G3, where the phone would stay at 100% for several hours, and by the end of the day would be anywhere from 30-50%. I received my S6 yesterday, got everything set back up and use the same apps as my G3, but within a couple minutes the battery was already at 99%, then 20 minutes later was in the mid 90's.
This is the first full day on a charge, with very light use, and this is what I have so far:
Taken off the charger around 6AM at 100%, and now at 7PM it's at 13%.
13 hours on battery
1h 32m SOT
I installed Greenify and GSAM battery monitor, hopefully that will help.

I think we've been spoiled by the LG batteries and then I went to the Note 4 so that doesn't help my comparison either. Today was better for me then yesterday though. Yesterday I was ready to take it back and tell them to keep it. Right now I've been off the charger for 90 mins. I'm down to 91% with 24 mins of calls and 23 mins of SOT.
So far my battery life is soso. Took off charger at 5:40am Saturday morning Eastern time. Currently at 21% with fairly light usage. Texting, little bit of Web browsing, some reading on Kindle app. I expect with normal usage I'll probably get in the 15-16 hour range. Which is uninspiring. perhaps an update will increase efficiency.
Cell standby is the #1 drain for me, comparible to many of the complaints in the main S6 forum prior to the vzw variant being released.

I think that is pretty good. Over 5 hours SOT and still 16% battery life left. Anything over 5 hours is very....very...good.
Looks to me like if they fix that cell standby bug we'll have a monster of a phone. 5 hours screen on time and its only 10% of the battery drain.... I'm curious to know if this cell standby bug is just a mistake in how battery stats are being reported.

I've seen a big improvement in battery today. No change in use. I have over 2 hours of talk and over 3.5 hours of SOT. Still have 22% and it's been 18.5 hours since the charge. My concerns are starting to go away.
Ok so here's all my info for you guys... I am on Verizon, and turned off the VOLTE calling when I got the phone based on the stuff I'd read. I had high cell standby usage. I turned it back on and it went awY to normal.levels, even with WiFi on all day and crappy signal.
I am using Nova launcher, and no theme. I do use a black background, basically a picture of a clear night sky with tons of stars. The day in the picture was a day of heavy Waze use with screen on, heavy Web surfing and some youtube. As few texts and some bacon reader.
I don't see volte calling anywhere I settings. I see "advanced calling". Is that it?
Verizon GS6

The problem doesn't seem to be SOT, but standby time. When I use the phone for an extended period of time, such as when I'm in bed for an hour, I only loose a few percent. However it seems to drain nearly as fast when it's in my pocket. This is why some get 5 hours of SOT while people like me who dont use it much are lucky to get 2 hours. Standby time seems to max out around 12-14 hours.

Yep I noticed this, got mine yesterday and to sleep at 89 percent woke up at 79. Lost 10%. Hopefully an updates helps because while in use It's fine.

My Verizon S6 (64GB black) also has Cell Standby as the number one drain on the battery. It's significant compared to my Note 4, where Cell Standby is much lower on the list, and which loses a lot less battery power when idle compared to the S6. Doing a full factory reset, wiping cache doesn't change this fact on my device. Good to see that others have this issue, though I wonder if Samsung/Verizon will really do anything to address it. I love some aspects of the Galaxy S6, but the battery life is an issue for me.

Yeah, this is exactly what I see. My S6 lost 11% of battery as it idled while I slept, with Cell Standby as the largest user of battery (by far) during that time. It has to be a bug, as my Note 4 (with Lollipop) doesn't have this issue.
So my first two cycles on Friday and Saturday were pretty normal and the phone idled incredibly. Then all of a sudden the last couple of cycles (and this one I'm on now apparently) are being killed by Google Play Services, even while idle. I hate that app (not really). I wish it was more clear what within it was eating up the battery.
My experience: Got a S6 Edge from Verizon Apr 10. I was having data issues where I couldn't load pages even though it said 4G. My Cell Standby was pretty high 30%-40%. I was attributing the poor reception to the Cell Standby. They finally gave me a new phone yesterday. The data issue was fixed but my Cell Standby is still high at 30% (I turned off Advanced Calling). I'm assuming this isn't a hardware issue unless I'm really unlucky.

Owners: How's the battery?

XZ Premium owners, how are you finding the battery? My Z2 and now Z5 have never guaranteed me a full day, and now that my Z5 is a bit older I'm charging twice daily. So I'm torn between the Z5P and the OP5, for all it's flaws -- is battery life better than the Z5? I'm particularly interested in dual-SIM, but I assume the battery life won't be all that different to the single-SIM handset.
My last Sony phone as a daily driver was my Z3. Battery was fine on that until I did anything that made the CPU go into meltdown.
On the XZ Premium, Sony and Qualcomm have got things nicely under control - which means the phone doesn't run too hot (which in itself plays havoc with the battery, and can make it near impossible to charge) - and the battery doesn't seem to take much of a hit even when playing video or taking photos.
My phone can still get hot when taking photos and give me the warning, but despite me using the phone heavily, the battery (given its size) works commendably. Especially if you enable any of the stamina modes
I could live with most of these modes enabled all the time, with the only issue being when using an on-screen keyboard (it missing characters pressed), and then the battery lasts even longer.
tl;dr - the battery is good and I'm very impressed. You should get a whole day of usage without fear, and with a good deal of screen-on-time.
I got this phone yesterday. My previous phone was the Z3 Compact which was the king of the battery life back then, but now i think the XZ Premium is better than the Z3c while i use certain apps and it consumes more battery only when i use the Camera, Photos app, Video app and Youtube. I haven't used Stamina Mode yet.
Mine battery life is good, my best was 31 hour running always under 4g with 4+ hours of screen on
I do a day and a half with every single charge at the moment
Thanks everyone.
@Katsigaros, could you let me know how you're getting on after a week or so? I don't plan to buy until the start of this month, so I'd be interested in progress.
@Tonyevol that's impressive for standby, but is 4 hours SOT good? I had the same response from a few people on Reddit, with 5 hours of SOT, but I though 6+ was kind of the norm these day, with good phones getting 7 or 8.
I am getting 5-6 hours SOT as of now. Over a month, I have seen marked improvement week on week. Once we get root/ twrp, we can disable some processes and programs that aren't required thereby maximizing the battery juice.
Little better than Galaxy S7 Edge which is my previous before. I am quite happy with battery.

After the first time I used it i performed a full recharge from 1 to 100 % to calibrate the battery. I am watching a lot of videos and because of that the battery lasts me 1,5 - 2 days. If I am not watching videos I can get almost 3 days.
I will have a clearer view on battery life after one month but right now I am very satisfied with it.
It depends a lot about the way you would use it. For example I'm all days around without wifi connection avaible and of course 4g connection all the time working drains a lot of battery juice. Also having Facebook running all the time with instant messaging always on makes differences. Without using Facebook and limiting display luminosity would grant a much SOT

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy S9+ before depleting the battery.
Then, drop a comment if you have anything to add!
I go my phone on thursday the 8th and I'm currently I'm getting about 3-4h of SOT.
I would say I'm a pretty heavy user, a lot of Podcasts, Spotify and Youtube (I've installed the Vanced version of Youtube).
I'm also not running the phone on 2k but 1080p settings. I have yet to enable batterysaving mode but I might try having it on medium where it limits CPU power to 70% and decreases background tasks.
Over night when its not plugged in i'm loosing about 1.4% per hour, during the day when I'm using it about 10-11% per hour.
Not really that impressed by it to be honest.
Although I'm coming from a Mi MAX that was designed for batterylife and that I modded to be as efficent as possible.
The phone is not rooted but I've just installed SABS, BK Disabler so I'll be disabling some bloat (I don't use SHealth, GearVR etc) and I'll see if it Improves when the phone stablizes over the coming days.

I'm getting about 3-4h of SOT with an unrooted Galaxy S9+. No power saving modes enabled and a lot of use such as Podcasts, Youtube, Spotify and such.
I am a heavy user. Today is my first full day with the phone. I restored the apps from Samsung cloud, and the messages from other phone using dongle. Yesterday I managed to fully charge the phone after restoring and configuration and it seemed fine as I achieved around 4hours sot and plugged the phone with remaining 20% battery. Today the battery went dead in below 3hours of sot and it was before 17:00, phone was unplugged around 8:00. This is not bad. This is shocking. I will maybe factory reset and restore everything from cloud, if the battery life won't improve, I will be giving the phone back..I have 6,5h of SOT on Pixel 2 XL which is satysfying. I was hoping to get around 5, but 2.5 is unacceptable.

Samsung is always like that at the beginning. Leave it to do it's thing and then check in a couple of days.
That's not my first Samsung, and I've never experienced that big battery consumption
Started of on my first charges with around 7hr sot, ended with the last two on around 3-4hrs, super confusing. I feel like the phone is draining so much in the background, so if i dont use it i wont get good enough SOT.
s9+ btw. Heavy user, snapchat/reddit gifs etc.
Are you guys using the exynos or snapdragon version of this phone?
Sent from my SM-G920T using Tapatalk
Exynos in my case. 7% batt with 3,5h SOT. That's a huge disappointment
23% with 5hr 18min screen time, 10hrs since charge. Also 3hrs of apple music and 1 hr YouTube over cellular.
I'm really happy with that.
Unplugged for 16hrs 9min. 19% battery. Screen Time 5hrs 42mins.
No complains here. The battery life is not outstanding but it is definitely acceptable.
When i turned on the device it had like 50-ish % juice and it managed to hold for like 6hours. Obviously not 6 h of SoT but just was using it on and off, installing apps, moving data, playing some media, etc...
Now its my first cycle since fully charged and i'm sitting at 50% with 4 hours of SoT. I did not do any gaming tho.
First cycle on my AT&T S9 Plus SOT over 4hrs and 52% battery life is amazing so far.

Well at 11% and got over 7hrs SOT for first cycle not bad at all battery life seems outstanding for first cycle will see how it goes once it settles after a week should get even better.

Early SOT Results
I received my Unlocked S9+ a little over 24 hours ago (US version). After setting it up last night and some this morning, I am finally on my first cycle of normal use. I am currently at just about 4 hours of SOT with 50% battery (see photo). I know it is way too early to measure the real battery performance, but thought i would share my early results. This is definitely on par with what I have been experiencing with my other phone (Pixel 2 XL) and the settings/apps are almost identical.
Standby battery drain
Charging the phone (S9+ Exynos) before bed, removing the charger and letting it drain the battery during the night, with wifi on, viber, WhatsApp & gmail syncing, I get a battery drain for the last couple of nights of 0.6% per hour, without AOD.
At least for me it's a bit better than my Exynos S8+ could manage.
Could it be, based on this post, that the SD845 version has better battery life than Exynos?

Not sure but it's all over New Snapdragon is battery friendly compared to Exynos , Which Exynos eats more battery. Snapdragon has got to the point is better in different ways from Exynos.

Someone mentioned having 4 hours SOT and they're at 50% on the Snapdragon. I'm on an exynos and I certainly would only be able to get 2.5 hours to 3 hours max on about 50% battery.
The question is, can the software be tweaked enough with updates to make the exynos more efficient, I wonder?
I am on exynos and have 4 hours en 10 minutes screen time when i am on 50%
The day before yesterday my phone was up fot 1 day and 10 hours and my screen time was 7 hours and 35 minutes.
AT&T S9 Plus Snapdragon as you can see SOT 2hrs and 1min on 72 % ,so battery life is is gonna keep getting better by the time i go down to 10% pretty sure i will hit 7hrs and half to 8hrs , I also get this type of SOT on my AT&T Note 8 Snapdragon , So not sure why Exynos is having battery issues.

Thinking about buying the phone. is there a fix to the battery issue?

Hi, so I heard that the batter is huge 5200 mah which is fantastic but unfortunately it's not working as it supposes to be, its working kind of like 4000 mah.
I would love to know if there's is any solution to that, for example maybe installing any ROM that fixes these fast battery drain or something like that, and also how much improvement is it?
I have a feeling that the new Mi 10 4800 mah will be much better than the 5200mah in the note 10, so I'm not sure yet which one should I buy. I do want the note 10 cause it has better cameras than the mi 10 and also smaller size, but I'm afraid the batter will be bad.
currently, I'm with MI 9SE
Thanks.
I don't have any battery problems so far. I have note 10 pro with global miui 11.0.13 from the box. Normal usage with 2-3 h with max resolution i Amazon prime video, i got 2.5-3 day without problem. I just removed all unnecessary apps. I come from s8+ and on 2.5y old samsung I still get 1.5day. So battery usage for my is something totally personal and depends on apps you use and yours needs. I need to mention that I'm at work 5 days in week for 9 hours without signal coverage, so my phone's searching signal for 9 hours, Bluetooth, wifi and mobile data always on.

Dont worry about the battery life. It is really great compared to other devices, it just could be a little better considering the actuals size, but that doesnt mean it has bad battery life. I charge my Mi Note 10 around every 2-3 days and didnt really manage to drain it in one day since i got it

You're lucky then. For some of us it barely manages a day on normal use - which is unacceptable given the battery size!
This depends on the way you use your Mi Note 10, for me, one and a half day easy ! I use Netflix, Boom Beach, Top Eleven, Youtube, Instagram, Telegram and Tapatalk, 7 to 9h of SOT.
I use 4G and when i´m at home i use Wi-Fi, so, compare to my "ex" (Mi 8), it kick is ***s LOLOL
Generally I have around 7 hours of SOT and I charge my phone every 3 days. The main battery issue I have is due to Whatsapp and has nothing to do with my Note 10.
The thing that helped me for a longer battery life was to disable fingerprint unlock. I get 10h SOT and 48h between charging.
My battery lasts 2 - 3 days on normal usage.
Wifi, 4g, fingerprint active.
I uninstalled almost all xiaomi apps except Themes, Cleaner and Xiaomi Store.
Hope an update will improve battery stats even more.
There is really no battery issue here. I am sure the battery life can be further optimized through an update, but it is overall very good.
I'm not a heavy user but I need to charge 3ach night I get about 30% left by bed time. My Mi A3 lasted about the same.

EU stock rom minus the xiaomi standard apps.
I'm mostly using the phone for maps, camera,browsing and light gaming (less than a hour of gaming). Neither of these should cause the battery drain I'm seeing.
Just today sith about 2h screen on time and taking around 60 pictures (rest spend browsing) I lost about 40% charge. That doesn't look normal?
Maybe it's a problem specific to the eu rom?
I think you can buy the phone. If you get the battery drain, then just reinstall MIUI. That should work. I am getting my bootloader unlocked tomorrow and then i will see if the battery issue will go away when I install MIUI.EU :fingers-crossed:
I have Mi Note 10 and I charge the battery everyday.
In 16 hours of use:
5 h of SoT,
1 h of vocal calls
Telegram, Whatsapp, Instagram Twitter
2 wearable connected
1 h music with BT headset.
At the end of the day i have 40-35% left of battery. I can't beleve someone could have 3 days battery life.
Fingerprint unlock drain battery
If you unlock it and install a custom rom like xiaomi.eu,miglobe which have almost no bloatwear and use something like nap time or kernel audiator you have much better baterry life than stock.usually i have about 10 hours sot or better with kernel fixes.i had 13 hours when i decreased the cpu clock by 25%.but is not good setting for gaming.

can you give more details about this? what is this MIUI.EU diffrenet than the stock MIUI? and what do u need to do to change it, is a root is necesary?
Thanks for everyone on replying here but it doesnt really help to compae each other batter life in "how many times you charge in a week", each one has its own use so if you charge once a week and the other one charge once a day it doesnt really say anything
I know that the battery is working well, like i said "its working like 4000mah", 4000 mah is a nice size of batter which can last pretty long time, BUT the battery is 5200 mah, if the battery is good enough for you, it doesnt mean that theres no issue; there is an issue, but u dont feel it cause 4000mah is enoguh for you.
As I see for now, theres no solution for that.. I thought that maybe installing custom ROM will fix these because the problem is generaly caused by the MIUI system right? so if we remove it and install fresh android, it suppose to extend the battery life dramticly cause it will now use the 5200mah batter, but it sounds like maybe the problem is more inside, maybe the number 5200 mah is not really 5200 and xiaomi just try to give it a baz name..
Thanks for everyone anyway

Try to backup your DATA in TWRP, wipe and then use the Global Version. I never used the european version and never had battery drain problems. With the update 1.0.13 the cpu frequenciy problem also seems to be fixed

You are right, installing a custom Rom improves battery alot, as i said before, it seems to be a System.img problem not a hardware problem so it can get only better with time. Also i dont think it behaves like a 4000 mAh. My GF has a Pocophone with 4000 mAh and i always have more battery at the end of the day even though i use my phone more than her.
And as i said before, XIAOMI didnt trick anyone, the battery size is around 5200 mAh.

do u recommend installing a ROM then? is it possible somehow without any root? i havent done this for like 7 years.. is there a ROM u can suggest that has for sure dramaticly improvemnt on the battery?
I remeber installing ROM was always annoying cause every ROM has some tweaks that not work right like Wifi or camera that constantly crashes.. is these things stil exist in ROMs these days?

No i cant recommend it at the moment. The only roms available are GSI's, so if you havent used roms in 7 years, i wouldnt touch them yet, even though the battery life is amazing. Also, you dont need root to change roms, but you have to unlock your bootloader and maybe TWRP for ease of use.
