Another battery moaning thread

I have read a load of threads relating to the battery life, but this is slightly different. I'm on jm1 official and have been for weeks, its was fine until a day ago, now I'm sitting at work, watching the battery percentage go down everytime i look at it, I'm now talking about now when I'm using 3g, just when phones idle.
I went to sleep last night and unplugged phone before I did, fully charged. Woke up and it was on 94%....
Really my question is, is there any way to find out what's using all my battery apart from the built in function which seems to only refresh every hour! I'm not looking for juice defender or such apps

Spare parts can give you, sometimes, some rough approximations. Really, if you started experiencing issues one day, you should try to remember what you downloaded most recently, it might be poorly coded and you should look to replace it with competing software.
Also, there are somethings you wouldn't want to intentionally or unintentionally leave running in the background. Use task manager (not ATK cuz it doesn't track "running" processes very well unless they've updated) to find out if anything is running. Even the marketplace will run in the background and not let your phone properly sleep.

Also, 6 percent seems about right. 2% for all services and 3g off, 6% for 3g? I'll have to look into it when I'm not on my phone. Especially if you dress your batteries by running them down to 0s%, this is bad to do to li-on batteries, I don't know how long it takes to feel the effects but short cycles are better for the batteries health.

Ok, 3g is never on at my house I can't get it there anyway.
The only reason I run it down to 0% is because I'm using my phone and it doesn't last, its stupid to say use it in low cycles because then I'm really only getting 20% battery life anyway...
I have advanced task manager but don't really use it from what ive read I shouldn't have to. And I had thought about the recent apps I've installed and I have installed nothing much new apart from angry birds
Just not happy with the noticeable change in the space of a few days.

If consumers keep "living" with things then they deserve the crap they get. As a consumer, you have the right to be heard so make sure the people you're giving your hard earned cash to is taking your feedback and providing products and services for YOUR needs, not the company's needs.
I'm loosing 10% every night too. It's a joke and I'm hoping the updates will improve it somewhat.

ye i know. but funny thing is, it's rather random. with the same settings and nothing changed at all. sometimes overnight, it drops close to none. and some nights, it drops 10%.
i've lost 10% over 4 hours today with no usage (idle) so lol. i'm glad i'm at least getting 2 days worth of usage.
let's hope this famous froyo does something. sometime soon...

Make sure all applications are dead (ie. use samsung task manager).
Turn off apn (so that you can guarantee no apps are using data).
If you do those two things, I'm sure you won't lose more than 5% overnight.
Personally, if I do that, I don't lose more than 1% overnight.

maybe it's due to over-flashing and all. de-calibrates the battery or whatever. either way, meh.
i've probably only got this calender widget refreshing itself every 12 hours to update the day's events and my Google account on active sync. maybe some applications screwing up somewhere.
to point out, a fresh flash always gave me no problems with battery draining. (after "re-calibrating")

just updated my phone to the TEST firmware JPJG8 which is currently the latest one available thru kies which includes arabic, and have seen no changes from the original firmware the phone came with ( Originally bought from Abu Dhabi with whatever firmware that had the android market not being available )
toying with juice defender for 2-3 days my SGS laged like hell even with the RyanZ lag fix OCLF from the market and it said that i saved 1.5% more juice tho i didnt see any diff with batt, it still drained fast (full charge overnight + extra charge with phone off on my way from home to work and starting @ 100% once leaving my car and ending @ 30-20% in the afternoon about 4-5pm, need to charge a little more if i wanted it to last till 10pm T_T )
deleted it today and thought why not simply use the extended control widgets to disable the connection when the screen was off + switch off the auto sync, like how the program did but manually and amazingly batt life felt like a big nasty battery i felt the diff immediatly.
kept the program juice plotter to see how steep the batt was used to compare the results.
1. keeping my phone on 2g almost all the time except for when i need to browse the net/use msn on phone - i do use facebook/twit and i might be missing the fast notifications but 2g is good with those 2 and battery life sure is extended as i can see.
2. closing the apn when locking the phone and bringing it up when screen is on is a great idea and u can almost instantly tell ur battery life is better
3. keeping screen off as much as possible helped my batt too tho i dont like it but it works.
really noticed a diff in battery usage today so im currently backing up the phone and after a fresh format/restore session will apply root and OCLF and keep you all posted on how long the battery lasts using this method
will test for 2-3 days before reporting again.
Current Battery stat killers are
1.loads of calls
2.display due to a large amount of sms's
see you again after my test in a couple of days

I don't think jg8's a test though unless it's a new rev by kies. used it a month back, pretty awesome but I've switched.
heading to bed now, shall see what happens tonight! such adventure and excitement every night.

jg8 isn't a new rev, it was out for a while and cant be found without using the ctrl+alt+u+p (and if that = test then its not an official release) at the firmware update in kies, its a middle east version with arabic support.
ok impressions on how things went.......
voice calls = 49% with 1H 13M 23Sec
Display = 35% with 5H 0M 9Sec
Cell standby = 7% with 16H 58M 44Sec
Phone idle = 4% with 11H 58M 34Sec
Android System = 3% with 42M 30Sec on CPU Usage and just 20Sec on CPU foreground
batt did last a full day for me i guess ending @ 6% when i got home
but what use is trying to save the batt life when i hardly use the phone
lets say i browsed the net for a 30min-1hour session, watched a few youtube video's/even downloaded video's for that matter or played a game or 2 for like 30 mins to an hour
ofcourse the display will be the major batt sucker by doing this and i doubt it would last an afternoon if i did so in the morning/noon time
I guess my only solution would be an extra batt or 2 for that matter if i really wanna show-off the phone and enjoy it fully for a full day. But the problem would be charging them all without a phone stand with extra batt charger
Anyways, does the batt last a full day for me , yes it does
am i satisfied doing what i did to make the batt last , N O

I got sick of my battery running out at around 3pm at work every day so I've now bought 2 extra batteries and an external charger from spider-foot.com

Well, greetings to all.
I just wanted to share my experience regarding the battery issue.
As I purchased the phone some 12 days ago, my experience is short, but somewhat effective.
First couple of days the battery lasted for app. 24h, with lots of usage (wi-fi surfing, lots of applications installation, calls, games, music, etc.). Then, I installed some "battery-indicator-related app", fully charged battery and used the phone for 15 minutes or so and went to sleep. In the morning my battery was at 80% !(it was on stand-by the whole night), and till 2pm it was at 15%, without using the phone at all.
Battery usage stated 64% "cell standby". I thought - what the .... ?
Than I did the next thing.
Uninstalled that crappy app, installed another one (similar, but other manufacturer),turned off the phone, fully charged it, turned it on, checked that wi-fi and BT are off, turned off 3G and syncs and updates, set brightness to lowest, installed black wallpaper, used task killer to kill all unwanted apps, and decided to see for how long will battery last with that settings and very little usage (couple of calls, sms and some sudoku playing).
The result:
4 days, 18 hours - since unplugged. Battery at 39%.

@ some of your replies
overflashing - ive only flashed once.
be lucky it only drops 6% when totally idle - the whole point in writing this thread was because ive previous lost 0%! when idle for hours and hours...
I have background data off (which i dont want to have to do) i have an APN switch which i use sometimes, but tbh its tedious and i shouldnt have to do this.
as far as im concerned, when i idle the phone, it shouldnt do ANYTHING

incredible s battery not soo incredible

hey everyone,
firstly, i just wanna say that the HTC Incredible S is a solid and terrific device, previously owning an iPhone 4 i might like the HTC better, except for some things...
The battery:
i read some reviews before buying and every reviewer seemed to love the phone and what the battery has to offer. I've owned the phone for a week, and charge it through the USB cable, connected to my PC, and sometimes the wall socket.
But it seems to me that the battery is a bit short.... if i want the battery full i will let it charge overnight, the next day i powered it on, sent a few texts and listened to half a song and the battery has already drained to 70%, coming to this from an iPhone 4 is disgusting.
I've got Auto-Sync and background data working, i like push notifications for Emails and Facebook and i like the weather to update on its own, also HTC sense incase i need to do things remotely, everything else has been set not to sync.
One of my favorite features is Auto Brightness, which is enabled on default, but when i check battery use it says that 70% has gone to the display, 12% cell network and everything else. I have a task killer that kills all processes when i turn the screen off..
Any help??

Wiping the battery stats a few times helped me, I used to recharge the phone to full battery and after unplugging it from the charger, it would drop to 94% in a few seconds...Oh, after 2-3 weeks, not after a week!
Also I get twice the battery life on Cyanogen 7.1, than on any other Rom I've tried...I get at least 2-3 days with good usage, tons of mails, sms, calls, weather apps etc. Wifi and BT always on. No juice defender or anything like that...

Dropping to ~95% can also be normal though. To preserve the battery the charging circuit should cutout when it reaches 100% charge and let it discharge to 95% before turning on again.
If you do wipe the battery stats make sure you read some guides and do it properly as I've found that more often than not it will have a detrimental affect (from needing to charge before it has fully discharged, or needing to reboot etc).

wipe the stats? sorry im still new to android but so far so good, im impressed with everything else in the incredible s, its very snappy and has a bigger screen vs iPhone 4.
if it helps, i have the phone fully turned off if i charge it overnight.
also, i read on another forum that while it's still brand new it needs to run a few charge cycles to strengthen the battery, if that is true.

It always drops to 95% when the battery is fully charged. S-ON Incredible S is not allowed to wipe battery status. Should I unlock it?

Yes, I forgot to mention...to wipe the battery stats you need to unlock the Hboot...If you have Hboot 1.16.000, then the only option is this:
http://forum.xda-developers.com/showthread.php?t=1337105
Unlocking the Hboot is giving you a few benefits, you get to install the CWM recovery and do a full backup of your Rom...Without unlocking the Hbtoot, if your Rom crashes, you can't flash any Rom so you have to send it back to HTC Service ...With the Hboot unlocked you can install custom Roms, you can restore a full backup, you can flash GAPPS etc, wipe battery stats directly from recovery etc etc...
So many benefits...
Now back on how to wipe the stats...The principle behind is simple, if 100%=4.3V and the stats are incorrectly set for 100%=3.9V, then you're never actually recharging the battery to full capacity, which is rubbish...
The way I do it is this - charge to 100%, boot into recovery and wipe the battery stats. Now use the phone until it's shutting down and then charge to 100% again.
Very important is to avoid rebooting the phone after the stats were wiped until the phone is fully recharged. Here is a thread about this process:

In my view, recharging while the phone is off makes no difference.
Yes, it's true. With all my Android phones I went through the same thing, first week or so, the battery was rubbish, but after about 2 weeks it improved a lot.

yeah, i've had it for around one week. so i might take your word for it and give it a chance, maybe for 2 weeks. i was thinking of bringing it back to the store but i'll give it a chance.
a part from the short battery at the moment it's a pretty terrific phone and i like it more than the iPhone 4.

Once the battery is conditioned, phone is rooted, custom Rom installed, bloat frozen out or uninstalled, then you can expect your phone battery to last a good full day with regular usage. No need to switch off when charging over night.

Well its incredible enough for me
It lasts a day, which is just right for me haha

Did u remove the USB immediately aft the charging?
Sent from my HTC Incredible S using XDA App

well i've had it for almost 2 weeks now. I charged again overnight last night and used it to listen to music and play NinJump/Bejewled on the way home today, battery uptime was just over 30 mins and the battery was down to 70% remaining. That's a bit quick if you ask me.

Not sure what's happening with your phone...but my Inc S has really good battery life, similar to Iphone 4...
At the moment is not rooted (that's why I couldn't take a screenshot) and it's on stock 2.3.3. With BT and Wifi always on, with tons of e-mails daily, browsing, calls (at least 20 minutes per day), tons of messages, etc etc
Screen brightness is always set to maximum and I get at least 2 days battery life, see attached photo...
I'm not playing games or listen to music...so I can't test that side of things and maybe that's where the problem lies.
What's your Battery Usage app saying?
Is there anything unusual listed there?

Maybe try disabling the Optus bloatware. Had a bit of an improvement when I did it to mine. Also be mindful about what apps are running in the background constantly, they could also have an impact on battery life. Screen is a huge battery killer if its constantly on, autobrightness can help slightly if you haven't enabled it already.

Thanx everybody for the replies

That battery usage sounds awesome! I have mine on Auto Brightness and WiFi turned off but its nothing like yours. My battery usage app says most of it has gone to the brightness, of course that percentage goes down when i start opening apps.
edit: im also using the stock Android 2.3.3 installed from the factory. and disabled my Advanced Task Killer, battery is still the same, but the phone now lags a lot less. so thats a plus for now.

When i first got the phone i noticed Optus loaded it with rubbish apps i'd never even touch. I disabled auto updates for the bloatware and forced stop for all the ones running. it doesnt look like i can remove them though :\

Hi when you get such good battery life, could you show us how long your screen's on for?
do you get good reception where you live? i find that seems to drain most of my battery.
Thanks

ok atm my incredible s is saying 4 hrs 26 min uptime and 1 hr 21 min awake time, 50% left. my signal here is great, the speed of the internet even beats my ADSL 2+ sometimes. should i be thinking of warranty back to store?

Before i rooted my phone i was charging my phone twice a day - this was nothing new to me as i had been charging my 3gs at least twice a day for the past two years.
However like somebody else has said, once the phone is rooted and all that optus junk has been deleted it lasts a lot longer. And you can notice the difference, my phone has been rooted for 2 days now and i have been on it none stop, modding all the appearence and downloading apps. I have been using it a lot more than i was before it was rooted and it has lasted at least twice as long. So for battery usage i should deffo root. Its HTC sense/screen that hammers your battery. Go look at battery usage and yourll see what i mean.
Also, i know this might sound stupid. But charging it through a wall socket (for me) seems quicker to charge, and seems to last longer than if its charged through a laptop/PC. Although ive thought this for my 3gs as well. If its actually true i dont know haha.

sounds just about right. my iPhone 4 needed a charge like once every 2 - 4 days, i thought it was awesome. On the Incredible S it says that 62% of the battery usage has gone to display, with very little apps on the list.
The optus apps are just sitting there. Because im on Amaysim i can't exactly use them properly because you need an actual optus account. ive tried opening some of the optus apps, they're mostly just web links and theres a Mobile TV and a Music Store app i believe, but i never at all use them. so they cant be consuming any data, memory or battery or anything, right??
Im still unsure about 'rooting'. Im guessing it's android's version of the jailbreak or a godmode on the device? i might need some help on it, i know how to flash windows mobile and jailbreak iTouch devices easily.
But then again, a lot of people have bought this phone, they cant all be experiencing terrible battery life and i dont think every user would have a root on their device.
I bought it from DickSmith here in Aus, the guy there told me there's a 1 yr back to store warranty. The phone is solid and one of the best phones i've ever had, plus a good price tag on it, its a shame to let a weak battery spoil it.
im thinking of returning it, but i heard somewhere it needs a couple weeks to strengthen the battery, if that's the case then there's no point getting a new one only to wait longer, ill give it a little more time. Plus HTC is releasing 2.3.5 software for the Incredible S soon, and wikiPedia states that it's got "Improved battery efficiency". but ill still keep root in mind for when i get more use to the device.

Yes, about 40min to 1hour display on... sometimes more...I will attach a screenshot once I get throughout the whole battery.
Yes, generally good coverage and mostly 3G...I'm on Optus.
My phone has been rooted before, but now it's on stock Rom as an experiment...
I would strongly advise on rooting, it changes the phone completely.
And remove any animation (live wallpapers) those are killing the battery.

Also found one more thing. If you've got Facebook installed it refreshes every hour, i set mine to never refresh, but you can still receive notifications
But i still don't get why the battery drains soo quickly, even on standby.
edit: found one more thing.
uptime and awake time. when i turn the screen off and awake time should stop counting as the phone is locked and im not using any apps, right?? in some cases i've noticed the awake timer still counts.
example: awake time will read 1:52:39, turn the screen off at this point. go back a couple hours later it's been counting as awake the whole time, and has half battery life it did eventhough i haven't touched the device since locking it and turning off the screen.
in some cases the awake timer will not budge when i lock the phone and turn the screen off and still find the same amount of battery life remaining when i come back.

how to get normal battery life?

Hello all
i´ve got my 4x Hd since one month now, everything is okay but the battery live is terrible. In some reviews i read that the phone should get 6 hours of screen on time and a lot of users here say that they reach 2 days with this phone but the maximum i reached with my phone was 20 hours with 2 hours screen on time. And no, i dont play ANY games on my 4x and the screen is nearly on minimum brightness. I have tried EVERY Rom in this forum (rom folder contains 80gig, lol) but it is very hard to manage for me that the battery lasts a day. Better Battery stats says that Baseband wakelock and wifi wakelock drains the battery at most (even on v10h and v20a,I thought that these wakelocks are custom Rom related...?). Also ive tried a lot of battery saving tweaks like greenify for facebook, trickster mod to reduce voltages and underclock to 1ghz, but nothing helps much. I ordered a second battery too (polarcell) and it gives a light improvement, but coming over an day ist quite impossible...
I would be gratefull if someone can suggest me a good setup (Rom + Kernel + Apps) or some tipps to save battery...
Sorry for my "bad" english....:0

It is nearly impossible to filter good knowledge from a thread which has been started months ago so sometimes it is good to make a new start and share the most useful.

6 hours is overkill of onscreen time. 2 hours is what you should get with heavy use, 3 hours with moderate, 4h and up with video watching.
install custom rom and kernel, keep wifi and data off while phone is idle and you'll get miniscule discharge while the phone is not in use. if you need to sync messages or mails, use dsbattery saver, and let it turn on wifi/data once per hour for 2 minutes and force sync.
keeping data and wifi off will conserve a lot of battery.
baseband_xmm is weird wakelock. try werewolf kernel, as it seems he completely fixed it from overeating the battery. as for wifi lock, it seems that it's rom-related, and that stock has best stats with wifi on, but a bypass of that issue, is ofc, to use wifi only when you need it.
as for underclocking & changing governors, i didnt find that they increased battery life much (for me). only advice is to experiment, and from personal experience see what's the best you can pull off. (f.e., carbon 4.2.2 i could pump 4+ hours of onscreen time with medium use, but i've tested other (better) roms, with more functions, that i simply dont want to go back to it )

If that is true then the OP should have been able to formulate his own opinion as to which ROM and Kernel works best for him. The simple fact is that if he's only had the phone a month and has tried every ROM then he has only run each one for about one day - that is not enough time to form any kind of opinion on how a ROM actually performs. By far the best thing is to choose 3 or 4 ROMs that have the features you want and try each one for a week, take copies of the Bettery Battery stats and review after doing those tests.

Don't tell me what I can and can't do. This forum is a complete mess because we constantly get the same questions asked over and over again.

Threads started months ago? Really? Try putting the word 'battery' into the forum search engine and see just how many hits there are - even one started 3 days ago. This thread is no different to a 'Best ROM' thread - you will get 10 people replying and 11 different opinions as to what is best.

I completely agree about the mess you describe but the mess will not stop by saying "search, read etc.". It's human nature, we're lazy.
Let those who want to answer, answer. Dumb and repetetive questions will be ignored anyway.
I'm sorry if I was being unpolite by my words, but that's definitely not what I intended so please let's not create more mess.

If everybody could understand this fact, there would be less questions on the forum.
No custom ROM or kernel can create miracles when the power consumption of the screen is the unchanging variable in the equation and you have to turn the screen on to use the phone.

Thank you, actually i´m using a modded stock rom (p880-eur-20b-f1.zip) and because of wifi and data issues i moved to the werewolve kernel v8 because it promised to get rid of the wakelocks but everything stays the same...Disabling wifi is annoying but possible for me, but disabling data is no option because i need whatsapp....and i dont understand how a lot of people here say they have a good battery life without disabling anything... :l Carbon Rom had alot of other bugs for me (needed 10 seconds to show the lockscreen), 4.3 version was even worse for me :l

The baseband, wifi and most of time nfc wakelock won´t go away, even if i use a rom 5 days, so where is your problem?!
Edit:
Battery had 31%, then i listened to music (turned wifi and mobile data off) and the battery was dead after 35 minutes, this can´t be normal, can it?

Wtf ??? When you listening to music phone runs 51mhz. I can listening about 2 days music. I think you have very many wakelocks I listen to music after 1h 2% was drained.

yeah, that's not normal. even with gaming it should last more than 30 minutes. my best advice is to dig deeper into the issue, see what's really wasting the battery. not many tips i can give, since my worst drainers were wakelocks, not apps using abnormal amount of battery while phone is active

[Q] Battery issue

I hope some one could help me ...
My galaxy I9305 have for 2 or 3 weeks now... leaked battery very fast
When i pull out the phone from charger at 06.00 AM (its at 100%)
when its 08.30 AM its about 80%
In that period is both wifi and data disabled..also gps and bluetooth
But the strange thing is .. from 08.30 AM to 03.00 PM
it only use about 20%
In that period i use my phone in my lunchbreak ,surfing facebook, mails etc..
and all the time is data activated..
So now i wonder.. is there a way i can get a normaly battery leak from in 8 hours ( about 25%)
Is the battery stats ****ed up.. or what could it be..
Im using a sentinel 6.0 Kit-Kat rom
I really hope that someone could help me...
BTW... all my apps is the same ... over 3 the last 3 weeks..

The first period i though is strange, case with everything disabled and if you are not using the phone, it should has decreased at max 4% in 2 hours (wich already is too much for me). I can't compare with mine cause i'm on stock unbloated and agni kernel.
The second period must be normal, if you said you were surfing through facebook, mails.. I assume you used your phone at least 3 hours with screen on. Screen kills most of the battery and thats normal. And you said you was on mobile data.. mobile data consumes more battery than wifi, so use wifi when available.
The best for you to help us help u would be take some screenshots of the battery usage at some times, because we don't have sure how many time the screen was on from 6:00 AM to 3:00 PM. Make another test taking some screenshots of battery usage in details so someone here can help you bro

ok many thx.. i will take some screenshot...

I suggest a read of this: http://forum.xda-developers.com/showthread.php?t=2551846
I know it's lengthy and most might not apply but it is what improved my battery consumption.

you're going through the battery at an abnormal rate especially if your wifi and mobile data are off... What type of battery do you have is it stock or something else?

Try this: http://forum.xda-developers.com/showthread.php?p=50441083#post50441083

Battery issue continued
i have now uninstalled a few program.. that was using much battery..
The one > mcafee Mobile security.... using very much ..
now its uninstalled... restarted mobile... installed again...
Now i got much more battery time...
So i think that program was ****ed up somehow...
but i will test for a few days, just to be sure...

A not so positive First Two Days with Galaxy S9

Hi all.
I buy the Galaxy S9 Plus, received two days ago.
Currently i have the January Firmware, no update here in Italy, that seems unstable right now.
Compared to my Oneplus 5t, sorry to say, but it is a bit laggier.
In those days, 2 times / 10 some application (Google maps - Twitter) have crashes or made the phone unusable (i have to force close Google maps three times yesterday).
Also, the battery is draining really fast, battery today drops with a medium usage to 10% after 2h of screen.
Hoping that the situation will be better with the new firmware.

2 days for testing battery life not enough the device still learning how u use it
for crashing and unstable for sure updates will solve that

The device isn't even officially released yet. Give them time to release the update that we already know is being released (already has been in Germany).
Allow more time for battery. A new phone has to learn your usage patterns before the battery is properly optimised.
If you're getting a lot of app crashes there's something wrong. Try a factory reset. If that doesn't work, return it as its faulty.

battery indeed drain very fast. I own a regular UK dual sim s9. compared to S8 which I previously own, sot is up to 1.5 hours shorter. basic operation heats up phone fast too.

I have none of such problems. No crashes so far. Battery life is great. Maybe faulty unit?

These are my battery figures so far.

I have had no crashes just yet. I managed about 4 hours SoT over an 18 hour day yesterday. Not amazing but better than my old 6P.
The device is lightning fast and keeps quite a bit in memory too!

Got the plus and had an ota yesterday. 1 fc of something I can't quite remember prior to update.
Been rock stable and battery excellent since then

I can tell you one thing when users report 5-7hrs sot and you just get 2, you can't blame the phone something is wrong with the apps you have or with some syncing issue

I will post in those days, some screenshot about my battery usage, so you can understand.
However, i will reset the phone tonight, so we can check if it's something wrong with my apps.

It is the usage pattern that counts as well as the apps, theme and so on. Some might not use Facebook for ex that is known to heavily drain battery. Others might have dark/black themes that helps, or medium batery saving mode...there are hundreds of scenarios. One user that has his phone set on FHD+ resolution wil have the battery lasts longer than one that has it at WQHD. Some might have smartwatches and devices that require permanent BT on or high location settings. All these consume battery so just saying mine has that much SOT or it lasts that much time, means nothing.
For ex, in the print screens above mix197 had 13 hrs of standby with 2 hrs SOT...2 hrs of doing what? Cause there is no voice call (and he has VoLTE active that sucks battery), no navigation, no nothing. Read the Bible for 9 mins and browsed the internet for 20...and having 13 hrs of IDLE. That's a graphic showing night usage...probably lasted like this since he was sleeping and the phone too.
What I want to say is that don't bother to compare your new devices with others....eventualy compare it with your old devices since those had the same apps and usage pattern (mostly). And read how to improve on battery: use a dark theme, disable un-needed packages/bloatware...including but not limited to Gear VR, Gear S, Facebook, Bixby if you don;t use, ANT+ and so on...deactivate BT, or set the mobile data to turn off when on WiFi (is in dev settings as I recall and it's on by default to switch quicker from wifi to mobile data). All these will help you get some more battery

The only reason people try to compare is to know if theres a problem with their device. For the s9+ it is the case as some are reporting 6-7Hrs sot while others are reporting 2-3hrs

I still believe that usage pattern and applications makes the difference. Such comparison should reflect something if same person was doing the tests. As this is not the case, results may vary by a large margin as I said. Besides that, the difference in hardware might be the binning (as it was the case with Note 8 or S8/S8+ devices). Could be that devices with higher SOT have higher values for nAsv too so that would mean they're much more power efficient and have higher performance too.

Ok, i think that maybe there are some serious problem.
Only 1h and 30 of screen on, and already at 57% of battery.
Something goes wrong.

Now you leave your phone for an hour or 2 untouched and see how it behaves. Look for partial wakelocks and alarms
