[Q] Note Battery drain? Rate Your battery Life!O_o?

Hello,
im thinking on buying the Note =]
i wanted to ask "heavy","excessive" users how is the phone battery drain ?>
*how long your phone lasts without charge (excessive,heavy use)?
*how long your phone lasts without charge (normal use)?

Im only use any of my smartphones with excessive,heavy use.
I have only 2 full battery circles and im using stock root rom/kernel.
All my phones was with very good custom kernels and lower voltages cause i wanted to stay alive during the day (8-23:00).
Now,my battery keep up the day but more easy than my previous phones (you can see which in my sign).
So, even my battery is new with few full circles, even im not using custom kernel for uc or uv, its better than my previous smartphones.

For a 5.3" display the battery life is exceeding expectations.. Based on my usage it has more battery life than the Galaxy S2 altho movie time is still the same at 8:30hrs to 9:00

I think it's very hard to define excessive vs normal use. Also the usage patterns of different people varies greatly. mostly because some use wifi on 100% of the time, others just turn it on here and there to check emails. Same for background sync and autosync which are battery drainers . So it's really hard to compare...
I keep my Wifi constantly on, background sync on, autosync is off but I have a task in Tasker to autosync every three hours manually. I have some push emails in K9 and twitter, gtalk and tapatalk syncing.
So on a day of super heavy usage the phone will last about 16-17 hours (ofcourse that includes about 7 hours of sleep time). With normal to moderate use I can make about 24-27 hours.

Hi people! I'm noob here! (wanted to write new but couldn't resist!)
I recently bought the Note and been having a few hard times with a couple of things.
One of the specifics concern battery life. Having been showered in the awesomeness of a 2,5 ma battery i thought the battery would be invulnerable but i was wrong.
The first 4 days the battery lasted me quite fine having to charge the phone once every two days. Heavy consumption was done for brief periods of 1-1:30 hours where i would try to shape my phone in the image that i wanted.
By the end of the fourth day i had a respectable amount of apps inside but not too many to explain the fact that my battery life now has decreased to 1 day.
I kinda panicked when i noticed the difference and went ahead to install Juice defender and advanced task cleaner apps. What's weird is the fact that before i did i would charge the phone before going to bed at night and then pull the plug when it would be full. By the morning the phone had lost about 25% while inert!
Noticing that i would go to the battery use feature in settings and see that the radio(!) which i hadn't been using was eating away my battery's life along with the screen which was inactive as a consequence of the phone in locked mode and a few other apps which filled the rest of the loss.
I tried to kill apps and i use Juice defender pro in custom advanced mode effectively rendering the phone dead after locking. It still consumes the same percentage of battery although now it blames the radio less and the live wallpaper more.
Am i to assume that my battery has reached it's "puberty" and that's "normal" from now on or is there a problem i just can't diagnose due to lack of experience?
This phone is my first android device. I do not know my way around it although i am learning more and more in a rapid learning curve.
Please note anything you might think has escaped my attention.
Thank you.

Your question is a little OT but i'll try to answer real quick.
25% loss of battery sounds about right if you have your Auto Sync ON.
Disable it and you'll go down to about 10% a night. Am i right or am i totally off here ?

I'll try it and see tonight. Thanks mfractal. Having been an IPhone 3G owner i gotta say, it's still kinda disheartening to see that 10% battery loss overnight is considered "normal". Will work my way around purchasing a second backup battery for emergencies.
Thanks again.

i also come from an iphone, and yeah, you have to make some adjustments.
you can take that drain to 1-2% if you disable Background Sync.

this was my batteries first full cycle. but you should get a general idea of how it performed.

this was what i would consider 'heavy' use, atleast by my standards. Edge only, Auto sync on, brightness at 75%, fairly frequent use.

Draining twice as fast after an update on apps this morning!
Hmmm, I have been using the Note for about 2 weeks now. With Juice Defender installed (with aggressive settings), I get by OK with the battery for a full day.
Well, that was until this morning when I ran an update of a few apps, and now I barely got to noon when the battery went completely drained. Same settings on Juice Defender.
Any clues on how to deal with this? I am thinking of reverting all the updates to double check.

guys, the steps to analyze battery drain are quite standard.
Download BetterBatteryStats (there's full version for free for XDA users, search the forum)
Download CPU Spy
Charge to 100%, reset statistics in CPU Spy and let the battery drain to 10-20%.
Then Analyze wakelocks in BetterBatteryStats and you will see which programs keep your phone awake.
If you want to make sure the phone is entering sleep mode and staying there, reset cpu spy stats before going to sleep and check in the morning. more than 90% of the time the phone should be in deep sleep. If not - again, betterbatterystats's wakelocks will show you what's keeping the phone awake.

That's EXACTLY what happened! I am stunned! I left the phone last night at 97% and found it this morning at 95%!!! When i saw it i was dumbfounded!
Thank you very much mfractal!

sure NP.
problem is that background sync is required by quite a lot of programs to function correctly. Hell, market won't even open with it disabled.

My battery life is pretty good atm considering its still a new toy and gets a heavy workout.
The battery life will improve over time as my usage will drop but with the screen it pretty much can replace my pc for any basic web stuff outside off the heavy duty work only a high spec PC is good for.

Disabling background sync defeats the purpose of having a smart phone, no?

I do like my phone and the screen real estate, and understand that, it can be major battery hog. But I would really like it to be super efficient when the screen is off.
I was looking at my battery drain graphs, (Settings>About Phone>battery usage) and noticed that my phone is active almost all through the night, (even when the screen is off).
So i loose 25-30 overnight, on IDLE.
Is this normal?
I'm using Exchange instead of the Gmail app for my mail. Does that use more battery?
Regards

Of course gmail use more battery like every app running in background and syncing.
But your battery drain overnight is really so much.
The normal is 1% per hour without any app syncing in background and about 2% or 3% with background syncing apps.So you must check your apps.Something draining your battery.
Overall,i don't believe that note battery isn't good.i think Samsung haven't done so good work in filmwares and apps.
I have removed the most of Samsung apps and my battery is great.
Maybe a update from Samsung solved battery issue.In nexus previous days released a filmware update which change amazing the battery life.users mention that they loose 2% overnight.And before this update nexus battery sucks!
So, we must pray for something similar in our note from Samsung...
Sent from the best smartphone, Galaxy Note...

Do you have auto sync on? If so please turn it off and watch the drain overnight drop to about 10%
If not then we got a problem

I got my Note two weeks ago and am since struggling with my battery usage as well.
It's hard to reproduce, but Android OS is the reason for excessive battery usage when the phone is idle.
Today I found this quite interesting. Please have a look at this screenshot:
Since a few days ago I'm using Llama to control some settings on my phone, but the drainage was present before I installed Llama.
When you look at the first gap in WiFi usage you can see the phone disconnecting from my WiFi router at home (TP-Link TL-WR1043ND) when Llama disabled my WiFi.
About 20 minutes later, when I arrived at the office, Llama reactivates WiFi and my phone connects to our WiFi access point at the office (TP-Link TL-WA801ND).
At this point Android OS usage goes up considerably and it won't stop, even if I disable the phone's WiFi.
Actually at the second, larger gap in WiFi usage I disabled the WiFi connection manually which caused my phone to stay awake until I activate WiFi again.
Edit: Using Titanium Backup I have frozen Wifi-Sharing and the Wifi Manager.
Apart from that, Wifi usage was never an issue on my old Milestone, where I had Wifi enabled permanently and the battery lasted for 4-5 days.
I'd be glad to provide more information if that could help figure out the cause of AOS's battery usage.
My phone is currently running:
PDA: N7000XXKK9
PHONE: N7000XXKK5
CSC: N7000OXAKK9
I installed FM-Kernel 1.4, hoping it would fix this issue. It did for a day or so...
Apart from the kernel it's the newest 2.3.6 stock ROM I received via FOTA though.

I easily get a good day out of mine with quite a bit of use. If use mine lightly I can get 2 days out of mine. If you are in need of urgent 3G switch 3G off to GSM to conserve battery life.

Sorry, I forgot to include it in my post.
Since I got the phone I have it set to 2G only, because I used up my monthly quota and am getting throttled to GPRS speeds anyway. So the 3G connection isn't the issue either.
Apart from that this happens in flight mode as well.

Huawei p9 screen on time

Can you guys post some screenshots what sot sre you getting?

Don't have a screenshot but I know I got +6.5hrs yesterday. I'll post a pic when battery runs down again. Still on MM.

In my opinion, P9 has pretty good Screen-On time.
Here is my average Screen-On time since 30th January 2017.

Have you been using the phone with full brightness?
In this battery test video, P9 with full screen brightness will last about 3 hours and 37 minutes.
In another video, a guy get 6 hours and 8 minutes out of his P9 from his normal usage pattern.
Most of the time, I would either be indoor or in my car. So, I think auto-brightness does not have to frequently increase screen brightness. That is probably the main reason why my screen-on time is good.
I also have an adblocker installed. Because Ad delivery system consumes a lot of battery.
This is an old article from 2012, but I believe it might still be true even today.
One example from their research, Out of 100% battery that Angry Bird app had used, only 30% was used by the game itself. The remaining 70% of battery consumption was used by tasks related to in-app advertisements.
If your phone is rooted, you can use Adaway.
If not, DNS66 is an adblocker that does not require root privilege.
Moreover, I mainly use my phone for communication (through Instant Messaging, E-mail, or web browser) and map. I do not have any 3D games installed. The most power intensive app I have installed is probably is Solitaire: Decked Out.
Additionally, some common causes of high battery usage are
- Proximity to cell tower. If you usually are in areas with bad reception, your phone will use more battery in order to connect to cell tower. Many areas have different signal strength for 2G, 3G and 4G LTE networks. Unless you really need to use high speed data, you can save battery by switching to networks that have the best reception.
- Wi-Fi consumes less battery than mobile data (3G, 4G LTE). Sometime people forget to turn Wi-Fi on. So make sure that you use Wi-Fi as often as you could.

Thank you soo much!!! Is there any way you can post some screenshots of your home screen just to see what other people have?

Difficult for me to give you an accurate SOT because I never charge my battery above 80ish % I never charge to 100% as it stresses the battery too much but I'm delighted with my SOT always use auto brightness. Coming from a 2 year old Note 4 the P9 SOT is outstanding!

Do you mind to share which firmware you are using right now? Recently I have upgraded my firmware and the battery life has deteriorated.

Question Asus zenfone 8 , I purchased a new Asus zenfone 8 dual SIM 2weeks ago . But the battery life is just shocking. Had anyone have any thoughts on this ?

Hi all
Just wondering if anyone who has an Asus zenfone 8 are having trouble with the battery life ?
Thank you

I'm not sure about everyone. I heard from some people on stock about 6-7 hours SoT, but i don't know how. 5-6 sound much real)

5-6 sounds about right . That's very disappointing considering it's a 4000amh battery . I would have expected slot more hours.

I find the battery life ok but in need of some tweaks (hopefully) on AOD, 2t2w, wakelocks, cpu governors and so on.
Hopefuly they'll put the effort into it.
In my usage, i shut off the 2nd sim when i don't need it, aod, 2t2w/fingerprint is on (w/out the aod icon), reception set on 3g w/ occasional 4g, 120hz (not that much of an impact) but i restrict some of the apps that pool lots of resources and (with a few exceptions) i have most of the battery optimizations on (adaptive bat, managed auto-start aps, bg app mgmt, w/ bat draining apps off.
On an average day outdoors, spotify streams on very high most of the time to BT (aptx hd), some occasional pics/videos, plenty of instagram, some browsing and some youtube. I usually go to sleep w/ 20-30% left. Charging is done w/ shed charging and ultra steady charging during sched charging.
It is my opinion that the screen on very high brightness just eats through battery (I mostly avoid extended usage in direct sunlight).
While excluding the 120hz refresh rate, second battery hogs after the screen would be the 2t2w, aod and the general standby opptimizations.
I hope they'll address some of these but otherwise I pretty much love the tiny guy - there had to be a comproomise for the specs and pricepoint.

I think 5-6hrs with moderate usage is alright
First of all it has an 888 and flagship socs in general are known to have an higher battery consumption plus the higher refresh rate (and depends if you use 5g all the time or if you get a better reception in your area and other usage)
You can optimise some stuff in Asus autostart manager,disable aod (which consumes quite a bit of battery) and some other stuff and get slightly better battery life though
But Asus might optimise battery further with otas though

I got a root. After that, I changed the minimum frequencies of the processor (they are high in the drain, no matter what mode we choose). Chosen by a conservative governor. Removed all Google software. I set the refresh rate to 60 Hz. Disabled AOD. Sim one is 3g, the other is 2g. But I still get the same 5-6 hours. I have a suspicion that the reason for the fast discharge is the radio module.

SAR value (head): 1,412 W/kg, SAR value (body): 1,582 W/kg (source)
I've attached the official SAR test report of the Zenfone 8, if anybody's interested.

Had mine a full day and the battery is appalling! Come from a p30 with bigger screen, smaller battery and less efficient soc and the ZenFone is draining about 40% faster. Came on here to ask the exact same question!!

Its strange, ZF8 has 4000 mah battery and battery is pretty poor. Seems asus lags behind in optimizing their software

Has there been any software update from Asus that improves the battery life? I've been reading that the battery is a big issue. I'm split between getting this phone or the Pixel 5. I'm currently using a s21U and have been using big screen phones the last few users but I'm ready to switch to a more compact phone, it's rare to find one nowadays. The market has more demand for big screen phones nowadays unfortunately and the current compact Android phone choices are very limited...

So, having used a few days now it has suddenly got much better. I'm off charge since 7am and am writing at 4pm and I'm at 80%. Not massive usage - 1 hour screen time with a little Pokémon go in between which seems pretty decent to me. I've disabled 5g, have screen on auto refresh rate and running latest firmware. I do wonder if low signal strength causes disproportionate power drain, the office saw me down to 30% by mid day work virtually no usage at all.

So I have Zenfone 8 since June and battery life is OK, I can get through a day. Saying that I am a pretty heavy user as I had to charge my pixel 3 twice in a day, while now when my father is using it, battery lasts for 2 days with 4-5h screen on time.
Here is my accubattery estimates. They have gone from 6h 10min to 6h 48m in the last week, so maybe the adaptive battery is affecting this.

Everything the same except AOD (only for night 8 hours) and auto-sync. Maybe auto-sync is the reason? It's setting in Accounts or some different auto-sync?

Thanks for your reply! Really appreciate it! Do you use two sim cards?

@dron39 just in accounts
@Harthouse no i use only one sim card

Question SOT is lesss really less

I've seen a maximum of 5 hours of SOT since I got the phone. My sot time is very short when I see other people's sot times. I always use the phone with the following features; +4G +always bluetooth +always location + no wifi +always sync +dolby atmos +dark mode +when i got notifications aod. Although I turned off the settings I used, I still could not do this for more than 5 hours.

Show us a screenshot of battery usage when you are at 10% - not at 80% - then we can see where all your battery fuel is going.

Sure its from 2 days ago

Battery is draining extremely fast on Android 12 (BULK) as well...
Is there a way to know if our phones haven't been manufactured by Samsung?
- There is Korea but also Vietnam etc... this might have an impact somehow?

What are you doing on whatsapp....that's a huge drain....

whatsapp is always a huge drain if you use to send and receive messages. My solution to this was enable multi-device login. I, now, use Whatsapp mainly on my computer when I'm at work and then revert to the phone when I'm off. The led to a huge difference. What used 25%+ for whatsapp..now stands at 4-5% over the day.

Morning 7 to 5pm I m using WhatsApp for work. I m using 2 WhatsApp. Work WhatsApp isn't stop every minute always receiving several message. I can't stop WhatsApp because of work. I think that's why WhatsApp percent is so much

I've seen a maximum of 5 hours of SOT since I got the phone. My sot time is very short when I see other people's sot times. I always use the phone with the following features; +4G +always bluetooth +always location + no wifi +always sync +dolby atmos +dark mode +when i got notifications aod. Although I turned off the settings I used, I still could not do this for more than 5 hours.

Does your battery run out by the end of your typical workday? Do you have to charge it during the day everyday, or can you get to the charger comfortably when going to sleep at night? SOT by itself isn't a very good metric when seen in isolation.

In a day average I have 4 hours screen on time and I m using in a work phone around 4 - 5 hours. That's mean every noon I m charging phone if not it finish before leave work.

So your battery level goes to 20% or below by every noon? Sheesh, that is indeed potato battery life...
But your screenshot suggests a pretty good standby time, nearly 11 hours usage and 72% remaining...
Maybe post the battery usage screenshot once your battery dips below 20% so we can try to pinpoint the issue?

Actually my battery level around %50 in noon. For example this screen shot is today after noon. In noon was %100

I am 90% sure that your battery drain is caused by the mediocre 4G signal which is used for internet at all times. A lot of power is basically being allocated to get a better signal and thus while you use WS all the time, your batt drains FAST. If you happen to have Wi-Fi for a day or two and the signal is maxed out, the battery will surely last longer. Generally speaking though, you cannot compare other peoples SOT to yours as most people do not use WS as much as you, nor 4G at all times.
There might be some other extra settings that could be altered to improve battery, like:
adaptive battery ON
enhanced processing OFF
location OFF
background data OFF
resolution to FHD
background usage limit to put rarely used apps to sleep
NFC OFF
nearby device scanning OFF
And of course the last version of android 11, as it seems A12 is not yet worthy or ruling the S21U. Sadly I have a feeling that Samsung might not fix A12 for the S21U as they are now releasing the S22. Hope I'm wrong.

The Big Battery drainers:
Screen - If you have manually set it high - Try Auto
Mobile Signal - Nothing you can do if its poor - unless possibility of WIFI
Location - Always On is a no no if you can help it - try use when app open only.
Background Data - Turn off for apps which its not reqd .
Also Since Android 12 I also seem to get lower SOT although my phone battery has been same since android 11. Im not sure if they changed the way they show/measure SOT now.

Question Excessive Idle drain / general battery drain

How much percent is your Vivo x90 pro+ loosing per hour? I am at 2% - this is pretty ridciulous I feel.
Installed messengers:
Wechat
Line
Signal
Facebook messenger Lite (nut not Facebook itself)
Whatsapp
Telegram
Social apps:
Instagram
email:
gmail
SMS:
google messenger
Phone:
google phone (because the inbuilt phone has inferior spam call protection)
Various:
Banking apps on high power use - none.
Garmin Connect - Bluetooth is on to sync with my garmin smartwatch and after activites my garmin edge 1040.
Sim card: - right now 1 active on 4G. But this does not seem to make any difference in power use. 4G or wifi seems to be identical in power use for me. Also having a second Sim card active or not does not seem to change anything.
Even overnight in airplane mode it's losing like 6-7% in 8 hours. During the day I lose 2% per hour. Vivo.pem is uninstalled - because with it I get no notifications after several hours of non use from several apps. On my old P30 Pro the same set of apps but actually some more banking apps on autostart/high power use I had only 1% per hour.
I feel like removing vivo.pem turns this phone into crazy battery drain - but with vivo.pem it's a brick.
Battery drain otherwise is
10% for surfing on Chrome 1 hour with Screen on at WQHD 120hz variable if indoors, 15-20% in bright light outdoors.
25%/hour for camera use
20% per hour for google maps with screen on in bright light.
So that gets me 6 hours of SOT with my phone at 5-10% at midnight. Not really good at all I feel. While the battery drain from surfing with Chrome is okay (not great, not bat - seems other phones aren't much better) the idle drain is clearly way too much. At 2% per hour that means 32% of idle drain from morning to night. My old Huawei P30 Pro managed with around 15% (and getting all notifications on time, no worries - and less other apps killed all the time and nearly 3 year old 4200 battery instead of new 4700 battery.. With proper power management this should be 12% here. Which would in turn give me 8 instead of 6 hours of SOT per day and be a good value.
AOD is off (because it's useless anyhow on the X90 as it cannot display many apps).

Would be interesting to see if anyhow actually has good battery life? In most reviews - if they are done somehow well and the phone actually been used - the battery life is pretty catastrophic - The best review of the X90 Pro+ so far that I have seen is this one - but mind its only in Chinese:
我想告诉你有关vivo X90Pro+的一切_哔哩哔哩_bilibili
从X50系列开始，vivo的产品力突然有了一个变化：外观设计、影像硬件、软件系统等方面都迅猛发展。半年一更超大杯并且从不倒吸牙膏，联名蔡司有真东西，产品线极其合理不和IQOO打架，vivo的发展有目共睹。看到国产厂商蓬勃发展，真的很高兴。相信终有一天，旗舰横评我们可以踢掉三星苹果，摆一排国产旗舰，骄傲的说出我们是最棒的。, 视频播放量 288928、弹幕量 2459、点赞数 18568、投硬币枚数 14047、收藏人数 3892、转发人数 854, 视频作者 凛光暗切, 作者简介 做手机体验视频的up主，商务vx：lgsumnscor（注明来意，相关视频：vivo X90...

Well and the reviewer used the phone as daily driver for at least 3 weeks, and he barely made it 12 hours! Not 12 hours of SOT, but 8:40 in the morning to 8:40 in the evening left over with 10%...
Huawei Mate 50 Pro and Xiaomi 12S Ultra with same usage would have been a little over 30% still - and that with the older Snapdragon 8Gen1+ which isn't as efficient and I guess the reviewer didn't remove vivo.pem..
Clearly the abismal software of Vivo here plays a big part - in summer my numbers will be minimum 25% shorter for SOT.
If vivo cannot fix the horrenduos idle battery drain - then I doubt the X90 Pro+ will ever have decent battery life. I really wonder where the problem is - because the hardware is supposed to be super efficient both SOC and display compared to older generation phones.

Just installed accu battery app, will keep an eye out the next few days.. But 2% an hour on average is not that much right ? This means your phone should last 100% - 7% during the night is 93% / 2% = 46 hours => your phone should last almost 2 full days...

2% is crazy bad. That means if I don't even touch my phone it's empty after 2 days. That's horrenduos. My P30 Pro actually does 6-7 days or so just lying around while still not missing a single email or notification. Yeah on the move it would be a bit worse - say 4-5 days. But I had 0.7% per hour average...
Oh and in airplane mode the X90 Pro+ still stucks quite a lot of power - while my P30 Pro would lose like 1-2% per day - so effectively I can let it lie around for 1-2 months then need to charge again without switching off.
Origin OS clearly has some severe optimization problems here (not sure about with vivo.pem installed and airplane mode - but that*s simply impossible because vivo.pem turns my phone into completely unusable..
And I'm not even using 5G which supposedly sucks your battery much faster than 4G (for now at least as 4G has been optimized for years now on hardware/firmware level).

OK... so the 2% is idle drain... I thought it was an average of using the phone during the day...
But you said 6-7% drain during the night... which is 8hours(?). So that is not even 1% pre hour... Why is idle drain half at night of what it is during the day ?

6-7% during the night in airplane mode. 2% during the day in idle.. Overall it's 1.5% whenever accu battery was running - which means airplane mode for 8-10h during the night and daytime in idle.
As you can see my average (albeit surfing a lot gives me a combined use of 19h50min for full charge down to 0... Yes that's a bit more than morning to evening - but far far away from making it into a second day. If I unplug it in the morning and would not recharge in the evening it would likely not make it to bedtime.. ..
Oh yeah - the quickest way to empty the battery for me is using google translate with camera. That sucks the battery at 27% when I for example want subtitles in a youtube video translated (subtitles which are inside the video - not a subtitle file - so there is no automatic way of translating - not sure if Pixel 6-7 live translate could do this on the fly...)

OK clear... I'll keep the battery app running the next few days and will post my battery usage...

I'm copy / pasting my response from the other thread.
My phone lost 4% in 9h, from 11:25 PM to 8:40 AM when I woke up. I had turned on: mobile data, wireless, bluetooth, location, alarm set for 8:40 AM, set for autostart have 6 apps and for microG autostart is not enough so I turned on startup. When I checked the consumtion, the only thing that standout was the Microsoft Launcher.
I have unistalled vivo.pem.

Better

Better to answer here:
I'll defnitely not do another factory reset - setting up this phone takes minimum 16 hours of time before I have all apps working again - without google backup that's a major pain. And no if I compare my times with many Chinese users it's still great. Many cannot get through 12 hours with the 90Pro+.
Are you using 4G, 5G, single sim, two sim cards? Which social media apps, which messengers...
Actually if I use the phone in battery saving mode the idle drain seems to be good, but while notifications seem to arrive on the phone (however without making a noise) - most don't arrive on my Fenix smartwatch anymore. But yes constantly running in battery saving mode got me good idle drain but again a not usable phone. so I have to go to ballanced mode in the normal settings,
Oh yeah - I had to enable on the battery usage the hidden "Unrestricted" mode - because with Optimized I would miss some notifications every few days for Signal and Line messenger. Either access this with code - or install "MIUI hidden settings app" - then under "All" click on "Advanced Power Usage Detail". Because this is not selectable by default (you can only select optimized or restricted, not unrestricted).
Oh and as you didn't mention it - I hope you ddin't start with 100% - because that is a random number - you need to start with 97% or lower for any serious testing as 100% is not full battery but less... The actualy max charge will differ but be 104-108%. So at the beginning seeing any drop is slow. Also I don't trust 99% and 98% after checking the voltage on Accubattery. So start any test with 97% or less - except a test that is full to empty.

Last night I lost about 13-14% charge. I did not use airplane mode. @extremecarver So that about matches your 2% an hour idle drain during the day. Not a big deal for me as I work from home most of the time, I have wireless charing in my car and can always charge my phone via usb on the laptop... But still it is a lot. I never noticed this because I can always charge the phone.
Using single sim on Edge (with 4g all incoming calls show 'unknown caller', forcing Edge data connection disables VOLTE and then I see incoming numbers/names. I do not have a toggle in setting to disable VOLTE). Wifi and location are enabled all the time. The apps that do not use the smart battery usage are Whatsapp, Tesla app, Ring app, Google clock, GMail...

Oh yeah - and maybe you activated sleep mode in battery settings? After missing notifications several times I had to deactivate that one too. But that would explain too for much lower battery usage at night. I want a fully working system with no single notification missed either on my phone or on my watch - something every other brand can do without problems. Actually I don't care if the notifications come only every 5 minutes - but if they don't come at all or 3-4 hours later - like often happens on Vivo - that is simply very bad. And it seems like I'm belong the majority of users with poor battery life - only the minority has good numbers (but likely very few apps sending notifications).
How many notifications do you get per day? I'm about 100 I guess. And yeah don't wanna miss them and any other phone I had didn't have those problems...

yeah I guess everyone getting notifications suffers from this drain. If you use dual 5G data it's worst. The 5g module seems to be pretty bad- as so many people in China now recoomed to use 5G only if you really need it on the X90 series... Seems like 2-3 years ago when all phones had battery trouble with 5G - but 2022 phones mostly got that right (like Galaxy S22, Pixel 7 where people didn't complain about less battery life with 5G vs 4G anymore).

Don't care about 5G (at the moment) 4G is fast enough for on the road. But at home I have a fast 1gb internet connection with multiple ubiquiti AP's, so I'm almost always using wifi.

Sleep mode is disabled, I didn't charged the phone, it was at 56% when I went to sleep. I'm on 4G network. My not restricted apps are WhatsApp, Instagram, Facebook / Facebook Messenger, Gmail, Revolut, another bank app, Vanced MicroG, Teams, Outlook.

yeah - but we all know to stay away from phones with Samsung SOC... I don't think it has drain that badly on 5G however (Pixel 6 had). The benchmark in general should only be 8+Gen1, Gen2, and Mediatek 8x00/9x00 phones (because Mediatek 1080 phones seem to be too good when it comes to battery life - but they have usually much lower resolution screens, often only 60/90hz - but yeah for standby drain there should not be a reason why a Mediatek 1080 phone is better than 8Gen2 - the small cores that should be the only active ones during standby / idle should not be consuming any better on a 1080).
Vivo X80Pro has horrible battery life on reviews - be it DXOMark or GSMArena which are actually testing a bit outside the lab too. DXOMark even has a pretty standardized test on the go/outdoors.. Idle drain there likely was a thing too.
Well as for battery saver mode - forget it. I think after 30 minutes of no use the phone doesn't give out any notification at all anymore. I think Battery Saver is pretty identical to vivo.pem. So not usable. As long as you frequently wake up the phone - everything works. As soon as for 30 or is it 60? minutes you don't use the phone - it goes into super deep sleep with only SMS and calls giving you a notification.
Idle drain was really good with battery saver on however. But it also killed Accubattery so no stats available...
I had installed Gsam Battery monitor too - and that one somehow survived. Basically with battery saver idle drain is perfect.
It clearly shows we would need some sort of battery saving mechanism that works normally, becasue battery saver and vivo.pem do not work (also not for Chinese user if someone brings this argument again - clearly Chinese users not only using the preinstalled apps - face the same problems.
It's too bad that without root there is no way to debug what is actually causing the drain besides 5G active.

So far (20 hours in) it seems Vivo fixed at least some of the battery drain in 4G in yesterday's trial version.
My battery life seems to have improved a lot, however notifications now arrive maybe 1-2 minutes late for many apps except those you just used before.
That would be an intelligent change. just push notifications once per minute.
In general I noticed the battery life is pretty good on wi-fi (except if wifi reception is very weak), but has been much worse on 4G data or even worse on 5G data. That may account for the big differences.

And well I managed to drain the battery today with 3:20 hours screen on time to shutdown.
Forgot to turn of google photos sync and my battery dropped like no tomorrow.. yeah surely the next 4G tower was 15km away. 800mhz. But I could literally watch the percentage dropping. The battery drain started literally as I took 150 photos or so shooting nice pics for sunset and the phone in the background trying to sync them. It literally lost battery like while running a benchmark like Geekbench nonstop
It's 4G/5G data that drains this battery like crazy. On wifi all is fine. As soon as you have average to below average reception the battery drain is crazy like I've never seen on another phone before. And surely it's not only me.
I tested against iphone 13 pro and screen off 4G data on same network at the same time with pretty identical speeds was 1% vs 5% for again a 20 minutes test. So fix that and battery life will be outstanding (yes on wifi it's better than iphone!). If that cannot be fixed this phone will be doomed for outdoor use if you need some GB per day...
Notice the crazy drain from 15% down to 3% with screen off. That was the phone trying to stay connected to cell data/towers on a bad mountain road. I didn't have anything running besides accubattery and closed all non locked apps to save some Juice. To no avail, if you have bad reception and don't switch off data that thing drains battery like no tomorrow. On the other hand it Vivo can fix the 4G and 5G drain and it's not a hardware but just firmware issue, battery life will be great. If it's hardware issue then it looks really bad for on the go.

So far overnight on wifi, bluetooth on, 4g on lost around 2% in 12h. Im on73% battery and 3h screen on time , 21h from last charge
