Hello XDAres
Read this as a foreword - it's not a must
I've been using my OnePlus One for about a year, and at first the battery was great, but after upgrading to CM12S it seemd like it got much worse. this case wasn't only for me ofcourse.. many other users of CM12s and basically any Lollipop device had complained about a decreased battery life. their evidence to that was their SoT- which used to be (and I'm talking about the majority) around 4-5 hrs back at KitKat days, and had dropped down to 3-4 once they had gotten the 5.0-5.1.1 Updates.
that was caused by a number of things- among of them was the Google Services Wake bug etc.
Now to the point-
My OPO used to get 4.5+ SoT ( Screen on Time) back @ Kitkat days. since the upgrade to LP it went down to 3-4 max.
And then I've tried something-
I simply changed the settings of display, to turn off the display after 30 minutes of screen idle (it was 15 seconds before).
And the results?

}
The suggested conclusion is- SoT is a lie.
If prior to the changes I've made on the display settings, I'd get ~15% @ the end of the day ( say 11PM/23:00 ) and a 3.5hrs SoT, I can now get to ~5% at the end of the day ( again 11PM/23:00 ) by simply raising those values. does it mean that I've used the phone more? well, no, it simply tells us that SoT isn't that trustworthy as we thought.
Opinions?
So, I have my display off time set to 1 minute and get the same SoT at the end of the day (6+ hours).
Stock CM12.1, no tweaks, no greenify.
Nothing changed since kitkat
It's not a lie, but it is a terrible measure of battery life. Sure the screen consumes a lot of power, but it's not the only thing eating energy, using the phone while the screen is on is a huge burden and especially when I comes to using the GPS there can be a huge disparity between a person that leaves the phone on a counter and a person walking around triggering the sudden motion sensor.

The SOT reported is not a lie, it's completely accurate. You're not thinking about this properly. If you previously had it set to turn off after 15 seconds, then we can be confident that when the screen was on you were actually using the phone and depleting the battery. Since changing it to turn off after 30 minutes we can be confident that after using your phone you'd put it down and the screen would remain on but the battery wouldn't be depleting like it normally would if you were actually using it. Of course you got more SOT, you'll always get more SOT if the phone is sitting on a table with the screen on but not actually being used.
This is the worst premise to start a thread with and to top it off the test you did is so bad I'm at a loss for words. You clearly disproved your point from the beginning. Your normal usage that you had on KitKat gave you more SOT than on Lollipop. Some people have different results though. Changing the display time out doesn't mean anything. You could have as well kept charging the phone not letting it reach 90% and shown a 12hr SOT and the second screenshot you could have reused an old one. No one would know

Have you both seen my suggestested connclusion?
I said that SoT isn't always turstworthy, that is my point, and I've showed that I can use the phone ( a normal daily usage ) for one day and get 3.5 SoT, and the next day I'd get nearly 6hrs SoT. and again, those are the results of about the same usage, the only difference was the screen turn off time.
Thus, we can conclude that people who post pictures of a ~5hrs SoT @ a LP ROM, or in the other and, people who post pictures of ~3.5hrs SoT @ a LP ROM, haven't necessarily have a 'worse/better' battery.
It depends on too many f actors, so we cannot take SoT as a confirmation of a good/bad battery life.

SOT is trustworthy just your test is dumb. It's a half baked theory and you're trying to convince yourself you got a good idea. Most grown people don't post fake SOT hence why it's always been a great indicator of battery life especially if usage patterns are similar (that's the key here). Other factors come into play like rogue apps but not the factors you're trying to manufacture with your lame test

Yes I read it, but your logic that you use to make your argument is completely illogical. The conclusion is right; there are too many unique factors for each user to take into consideration, so two users with the exact same ROM can have wildly differing battery consumption experiences. I say this to anyone asking about battery life on a ROM or build: the only way to find out is via your own testing.

I see that it is hard for you to say what you have to say without being so rude, for an unknown reason.
I'll still answer you-
Person A- Gets 5.5hrs SoT and he is happy.
Person B- Gets 3.5hrs SoT and he isn't happy.
Both use the same ROM, and both get to 11PM with 15% Battery.
Person A- read emails for a few hours.
Person B- only used facebook a little, navigated for a few minutes, used whatsapp and played Temple Run 2 for about 30 minuets.
both batteries lasted for the entire day.
Person A's phone mainly drained the battery for using the screen- thus the higher SoT.
Person B's phone mainly drained the battery for Data Usage,GPS,GPU etc- thus the lower SoT.
Person A- thinks his battery life is awesome.
Person B- thinks his battery life sucks.
both of them get to that conclusion by checking their SoT.

You're still not getting what I mean and used a very obvious example. I am specifically focusing on YOUR experience, not usage patterns between two different people. You had better battery life on KitKat and I assume your usage patterns and apps have remained generally the same. That's why it's logical to assume Lollipop has worse battery life due to different SOT.
The difference between two people can have too many factors to even bother considering. But judging from your own experiences on different ROMs or Android versions you'll get a clearer idea that your usage will give you. But this assume that the usage is NORMAL not increasing time-out to 30 mins to manufacture results to prove a point

You had to make a thread for this? Everyone knows this stuff.
Which is why when posting SOT stats its common to post your App usage stats along with some description (like WiFi/data usage, Location active or not, auto sync on or not)
I too find your thread absurd just cuz your little experiment has such obvious results it's ridiculous you had to point that out.
I prefer better idle drain rather than high SOT
SOT is a lie for "end users"
I have went up to 8.5 hours of SOT with 40+ mins on call with CM11S-05Q, and on average was getting 6.5-7 hours of SOT with 1.5+ hours call time on 26-32 hours frame.
Moving to COS12 was a bummer, but with COS12.1, just a few days back with some more modification with Amplify was able to get a staggering 6.5+ hours SOT which I had been getting with Custom ROMs like AICP easy ...
So it jots down to the user, how is the user is using the phone, what has he done over the stock behavior of the phone to boost the battery performance, Amplify, Greenify, OS tweaks, myandroidtoolspro etc comes handy.
Again, if you use the phone with stock behavior, you wouldn't be here at XDA.
Oneplus One has best battery performance I have seen in years, since the time of Motorola Atrix 2 and recently Droid Turbo. Motorola had been ruling in battery domain since beginning of android smartphones, cause they were the dudes who made cellphones to begin with, and the only device in which I saw a similar performance is OPO. So SOT isn't a lie, absolutely not.
Lidor, the issue you have is Mobile Radio Active Bug, Google it.
SoT is not intended as a general and absolute battery meter.
It does what is says, it tells you how long the screen has been on after unplugging it from a power source.
Note: Of course when the screen is on consumes part of battery life.
So, SoT is not a lie, is a honest indicator of how long the screen was on.
Why the screen was on? That's the real question, and SoT is not competent to answer.
SoT alone is not enough to compare the battery life between os versions.
What if someone asks: How long will the engine of a car stay on with 10L of fuel?
This is my (educated) Opinion regarding SoT.
sot emm.

Yesterday a post was made to /r/nexus5 on reddit about how battery life was getting worse as time went on. Over 100 people replied saying that their phone was getting worse battery life as well. Here's the link: http://www.reddit.com/r/Nexus5/comments/1yxj2g/battery_life_went_from_insane_to_terrible/ The most people were able to find out was that there was a problem with the Android OS process. Are you guys having similar issues? And do you have any fixes?
Batteries do lose their max charge over time. We're now 6 months aged for the first purchased devices, so it could simply be those batteries are starting to age. They still have years to go, but a brand new battery will always be impressive.
It's one reason why I silently laugh at people bragging about great battery life for a brand new device. of course it will get good life, it's a new battery running optimized software that isn't pushing the hardware as hard as the software 2 years into a device life cycle.
posted by people that know nothing..
as time goes on, you install more and more apps. many apps arent coded very well, and have other issues. anyways, people get more and more of these crappy apps that will drain more and more battery without you even using them. anywho, not a problem here. i get pretty much the exact same battery life now as i did months ago.

great battery life for an "old" device, 5-6 hours screen on time every single day. the batteries life doesnt reduce that quick, and generally youll change phones(within 2 years) before you see the life of your battery shorten.

6 months isn't going to be noticeably less max charge unless the battery was severely abused. Also the phone has been out for 4 months and most are younger.
Here's something to think about: Usage patterns change. People install new apps.
Sent from my Nexus 5 using Tapatalk
Indeed usage patterns play a massive part. And some of which can be completely out of your control.
At home on WiFi I'll get 6-7 hours of screen time.
At home on hspa I'll get 5-6
At work on hspa I'll get 3-4
So at worst case scenario I can lose half of my normal battery usage just based on the carrier performance.

I get about 3-4 hours SoT daily... If anything, that has gone up since I got my device (one of the first batches shipped in US).
I wish I could get 5-7 SoT, with numbers like that, I'm beginning to think I'm doing something very very wrong
Point is... I have one of the first phones shipped out, and my battery life has stayed exactly the same.
High battery usage by Android OS is probably good indication that there are some wakelocks. It has nothing to do with battery being "older".
My battery is great from day one.
Captain obvious mode now:
Posting SoT is pointless and proves nothing. It really depends on what you are doing when screen is on. It is really obvious that it is not the same if you read some book with 5% brightness or play a game.
My SoTs go from 2h up to 7h, depending on usage...

wake lock is main reason makes battery drains so much. try to use greenify to hibernate apps.

LOL. Yep. Give me a day and I'll show you screenies of ten hours of SOT. It'll be BS because to get those results I have to set my phones brightness to less than stock. I also have to set screen timeout to 30 minutes. As well I need to remember to turn the damn screen back on after 30 minutes. I also have to make sure my phone is in my sock drawer doing nothing when the screen is on. It'll still show 10 hours SOT though.

Yeah, the common problem.... My battery just is used for 5 hours.
But there are some fixs to follow:
http://forum.xda-developers.com/showthread.php?t=1168036
I posted my usual screen times on a typical day for me.
Typically I do the same things which are a lot of xda and viewing the verge and YouTube. A few calls and texts.
And from my experience the difference between being at home with WiFi off and being at work with WiFi off is that my battery usually lasts nearly twice as long at home.
I was trying to get across the message that your carriers signal strength plays a massive role on how long your battery lasts.
So say if a mast went down and you get bumped onto one a bit further away (they don't rush when fixing these things unless it's a critical one). You would have done nothing and all of a sudden your battery life has started taking a massive hit.

I'm also having this problem with the android os draining my batter And this started happening within the last week or so.I used to be able to easily get about 30 hours out of my phone, now I'm only able to get about half that. As you can see in the 4th pic, android os has been the cause of a 3h45m partial wakelock, which doesnt seem right to me and is probably the cause of most of the battery drain. the last 2 pics are something that also seems weird to me, as google accounts manager shouldnt take 4% in about an hour. I dont even know why its running that long. Though i know how to quick fix the account manager drain (simply disable it) the android os isnt that simple as i dont know how to see exactly what apps or processes are making it cause a partial wakelock.

I had a similar issue a while back, and in the end it was Google location reporting within Google now service. Try to switch location reporting off but leave location history on and see if it helps. Also choose Location mode to battery saving.
Turning off location reporting does not affect Google Now functionality...
It can be something else in your case, but this problem was common...

One thing I've noticed as a weirdness is the cache of a phone can get stale and so it gets into some weird loop that drains battery or something and clearing the cache improves battery life. Also sometimes apps can develop bugs or new wakelocks when you do an update so sometimes you have to stay on top of it to track it.

If I did not use some preventative measures to prolong battery life I would maybe get 14-16 hours in a day of usage, I always left wifi on, bluetooth even when not connected, data, force LTE, etc. I did not care because I charge my phone every night. I just find it silly if I get a day usage out of my phone and it is at 50% well assuming you use the phone the exact same as the last day you will use another 50% and it will be dead by the time you get to your charger.

Its insane lol Iam coming from a htc one and this easily lasts double what i got from the htc! Now i have adjusted my settings to help with battery life, I always do when i get a new phone. I turn alot of stuff off that aint being used and only turn them on if need be! None the less this is by far the best battery life i have ever experienced from a phone! It also drains consistently where as with the htc it used to drop from 100 - around 96 within a few minutes and then when it got to 30 it seemed to suddenly start draining faster! I took this off charge at 100 and left in standby for over 4 or 5 hours and it was still at 100%
I had great battery life when I first got mine. Since I updated the software, it's tanked.
I have repaired and factory reset it and i've optimised everything with battery savings, but went from 8 hours SOT and two day battery to around 6 screen on and at about 20% when I go to bed after one day.
HTC One M8 gave me around 6 hours screen on time, and lasted a day and a half.
Hoping this sorts itself out, as the screen temperature issue, speaker notification volume, and now battery life, is not enough to of justified my jumping ship :/ (Even though I really wanted it because it's waterproof) lol.
All that said, the battery life even now is excellent still.
It's not that good as some people say but still ok. I would say that maybe 20-30% better than htc one m8. This means that you can easily go through the work day but if you would be go out after the work day (partying) you would be a bit worried if the battery lasts.

I have hight demand about battery life but I'm also happy with Z3 dual. I wish it can be charge ( much ) faster by microUSB port, best could be about 2 hours.
I am actually disappointed by the battery. It's down to 80% after just an hour and a half with medium usage. How is it going to last 2 days like that? Don't know if my phone is a faulty device or I am doing something wrong. It's charging now, I will put up some screenshots if it's still bad. Everything else is perfect so the battery being bad (which should be the best thing with this phone) is making me sad :/

Been unplugged for about 9.5 hours. A lot of whatsapp usage today. Battery life currently sitting at 65%. About half LTE and half WiFi.
This is a lot better than my Samsung S4, but not sure how it compares to other users.
I'm actually curious if anyone has compared the z2 and z3 battery performance in real world usage with the same usage pattern? Which has the longer sceen on time and standby time etc.

Nothing special
Could anyone tell me if this looks right? Is it good or bad? I didn't charge it overnight so ~10 hours are included in which I didn't use the phone.
Here's my battery usage the first day after I got it (charged up to full overnight before starting to use):
http://imgur.com/a/RyftP?gallery
Summary: 13.5 hours on battery, leaving me with 6%, with 8h43m+ screen on time and 3+ hours of music. Coming from a Nexus 4, I'm very very happy.
coming from LG G i'm very happy.
I'm struggling to get 4 hours of screen time before it dies after less than a day. No apps at all hogging the battery or anything like that.
Standby battery seems to be awful, even with stamina mode on blocking everything other than facebook messenger and gmail. It's losing 1% an hour, which doesn't sound bad, but my Galaxy Note 3 was draining 1% every three hours on both stock rom and Cyanogen 11. Moto G 2014 similarly does around 1% every 2-3 hours.
Standby for the most part should be represented by an almost perfectly straight line in battery stats, but on the Z3 its a constant curve downwards, much like the standby battery bug in the OnePlus One.
I'm in a full 4 bar LTE area as well, so it's not poor signal doing the damage.
The strangest of all, is the first day I had the phone it managed to get me through 2 full days easily. That included 8 hours of music streaming over bluetooth each day, and 4 hours screen time. Yesterday I was just over 3 hours screen time after 17 hours, and it was on 6% battery, including the 8 hours or so music streaming. That is exceptionally poor compared to both the Note 3 and Moto G.
But who knows, maybe disabling all the bloatware is causing issues. Either way I'll have a replacement device from amazon tomorrow which hopefully wont have the screen issues or bluetooth/wifi dropouts (thoguh I suspect that is software related).

go into your battery settings and make a screen shot
I had z2 so will offer comparison on battery. It does last longer than z2 by approx 20-30%, on my usual usage with z2 I was at approx 15% remaining by end of the day, with the z3 I'm at about 35%ish.
Heavy use and relatively bright screen.

Post here your findings with the A9 in daily use; or discuss methods to improve battery life (settings, etc)
How much screen-on time do you get? How long does your battery last through the day, with what type of usage?
Mention also your ROM version pls.
If possible, post screenshot from GSAM or similar app.
inspired by similar thread for the M9 here: http://forum.xda-developers.com/one-m9/general/battery-sot-t3067585
ps: I am in the process of chosing a new phone, which could very well be an M9 or A9.
I'm generally a fairly heavy user and I've been very pleased so far with battery life. This phone and OS have so far been much better at preserving battery when asleep and it charges much faster even from standard chargers.
Well I am more then pleased, and if you use the phone as a game console only and watch videos, then it uses more power, but it is a phone right?
Thanks for replies. If possible, please post numbers (screenshots appreciated).
E.g. how much screen on time in a day, how much % left when going to bed without recharging all day.
+ add ROM version, whether 2gb or 3gb RAM...
you know, the essentials to make comments comparable.
Personally I am still on a 2.5y old One X+ that I want to replace. I don't game but need about 4h SOT (browsing, social apps, ...) without recharging. Today, I need to recharge every day during the day, and I want to put that behind me. In gsmarena battery test, the One A9 scored barely better than the X+, and worse than M9. That has me worried.
/ Updated to add: I also need all day mobile internet on 3g/4g, and 1 hour streaming radio (tunein radio app) with screen off). Maybe in future all day bluetooth for a connected watch? /
Cheers

Thx. I updated my requirements though. I'd been too brief
besides, this thread is meant to collect data from many users, to provide usage examples to all potential buyers
From my experience my a9 battery usage is impressive when the screen is off, but when the screen is on it's worse than hTc one M8
in the M8 the SOT I got is between 5 to 7 hours, and in my new a9 the SOT is 4 to 5 hours per full cycle!
this 4 hours screen I used them in 1 day and half, with all time wifi and sometimes 4G Data when I go out.
I will post Gsam battery stats in the next couple days.
Marshmallow's doze mode works as advertised, with seemingly infinite standby times. But there's only about four hours of SOT in the tiny battery, maybe almost five if you're miserly.

That's about like my M9, which is what I expected with the A9. M8 was way better on battery than the M9.

810 is a battery hog. All that heat is wasted power.
But there's no excuse on the A9. Anybody could tell you a 2150mah battery isn't gonna last long. Would it really have been that big a deal to make the phone 2mm thicker and put a 2500 in it?

Yeah, I agree. Personally, I would rather a phone the same size and the M9, with a 2840 battery, but with the 617 proc. But I'm probably not exactly who HTC was targeting with this device, either.
I was just saying that I think HTC decided that if the A9 battery performance matched the M9 then that was good enough. Once I faced fact that the M8 performance was a thing of the past, the M9 has actually been decent for me, using a custom Rom and flar's ElementalX kernel.

Day 1:
I unplugged my A9 at 7am.
3 minutes of scrolling through facebook. Then drive to work.
7pm the phone vibrates and tells me I have 15% battery life.
I made 4 phone calls all less then 5 minutes. Turned the screen on maybe 10 times to do a time check. And spent a good 15 minutes on break scrolling facebook.
12 hours of almost non use...
Then the fast power dump came.
My 20 minute drive home it went from 14% to 2%.
This is crazy.... I may have to return this thing and get my M8 back.

That battery will definitely be sufficient for the "average user" (by average I mean 9 to 5 day job with 1 hr lunch break and a 1 hr commute from home to work) that listens to music or watches movies on their way to work, uses their phone on their 30 minute or hour break, and watches movies/listens to music on their way home. Your battery stats are pretty good for 24 hours. The "average person" is out the house for about 12-14 hours a day and have time to plug unto the wall for atleast 15 minutes. If you can charge your phone for just 15-20 minutes while you eat on break (like most smartphone owners probably do already) with quick charge 2.0 (and soon to be 3.0) you'll have more than enough battery to last the day, and some, until you get home to charge for the night.
People who are complaining about the battery life must use android wear devices, wireless headsets, and keep your bluetooth on all day , and/or, are business men who are always traveling and don't have time to charge your phone, outside of those reasons I don't see why someone would need an incredibly large battery. I think that the fact that Android devices have been known for poor battery life for a very long time and people are expecting android 6.0 to be just as "battery hogging" which is why they think the 2150 battery is too small. Efficiency plays a huge factor that people are just ignorant to because they haven't used a marshmallow device or an iphone to understand it. Small batteries CAN last the day with the right operating system. Apple puts small batteries in their devices to maximize profit, but what if they put a 3200 mAh battery in an iphone 6s. the battery would probably last 2 full days with average usage. Point being the efficiency of android M seems to work wonders here. I'm wondering how much longer the Galaxy s6 battery will last after it receives the M update.
And to those who claim they don't have enough time to charge their phone or "find it annoying" to have to charge through out the day, you sound ridiculous. There are car chargers for people who drive, somewhat large (and affordable) portable chargers for people who commute via public transportation. Quick quick charging 2.0 & 3.0 . all you need to do is charge for 15 minutes, if needed, throughout the day and then you should be fine.
All in all, the average user should be fine with this phone. For you people that want a 4K display phone with a snapdragon 850 with a clock speed of 3.5GHz, along with 1 week battery life and 56 hours of screen on time for under $450, need to just pack it up. It's 2015 not 2051. Every phone will have its pros and cons. That's reality. If this phone isn't for you, then it isn't for you. Simple.

If this even is true, then you have a bad unit, I use mine like u describe and I got atleast 70% left when I come home from work.
At first I thought battery life sucked, but turned out to be a couple of bad apps (Sony life log and smartband). I ditched them and now getting similar life to my M8.
Last night I fully charged it then unplugged it to see how much charge it lost over night, so over 7.5 hours it lost just 2%. , which compared to the m8 (lost 9%) I'm pretty impressed.
Charge rate seems better too but could that be because it's such a small battery?

I checked the battery use last night. Facebook. ( Which surprisingly didn't come loaded) used 46% of my battery Yesterday ( Per Battery Use stats. ).
There is a good chance it is hogging. ???
As it stands now. I had the same morning and now I'm at 82%. It's been off the charger for 2.5 hours and I've only responded to a facebook message.
I have already turned off unnecessary settings to include enhanced 4G LTE calling .
Hopefully I'll see how it goes.
My screen is on minimum and it has already dropped from 82% to 80% in the time it took to write this.
This kind of feels like the Old days when the HTC EVO came out.
That is NO news about fb app. Never used it never will.
After a couple of days of usage, the phone is doing about ok for me. Screen on time is just as bad as phone idle time is good. Put them together and they are lasting my average work day.
Had plugged it out yesterday at 7 in the morning and when I returned at 5, it was 33% which is acceptable , given that it had been on Wifi and 4G through the day.
I just left it unplugged from the charger last night and the Doze feature really shines through. Screen shot attached.
Is it worth upgrading from m8 to a9?
Im thinking of getting the new a9 but dont know wrther to get an m9 instead. I am currently using an m8 but want to upgrade. Should i get an m9 or a9? Im sticking to htc phones as i like the desighn.
I was using my phone as usual, until I noticed that the battery haven't gone done for long, it lasted longer that usual.
No, power save mode was on.
No, greenify.
No cpu control to drop down the cpu freq.
This was on normal use.
I don't know how my phone did this, but yeah.
I took the first ss at 4%, after this, the phone went on to be on 4% for 15 min when screen was on the whole time until it dropped on 3%.

Although I was using instagram, whatsapp, snapchat, browser and internet as usual.
And it took 25 mins to completely shut down.
So the phone gave me approx 9 Hours of SOT.
I am not sure how this happened. But it did.
The same phone use to give me 4 hours on Android 5.1.1
Then 6 hours on Android 6.0
But now it gave 9 hours.
That's it I'm RMAing this phone I get like 2 hours sot with amplify, greenify and powernap and even less without that. Now I know this is not normal. I am weary of dealing with Moto customer service but I guess there is no avoiding it jow

No buddy dont use so many apps they interfere with Doze and other MM features. I tried using greenify my battery dropped. Then I removed 'greenify' and 'prevent running' from my phone I also used to use setCPU to drop the freq when the screen was off but that to hogging my battery, I guess that happened because it had to change the freq many times.
I removed setCPU too.
This was without any battery saving app.
Try doing that.
Unbelievable!

That's fairly average. I usually get between 4-5. You'll never see 9 hours and the probability of anyone else seeing it is about 0. I have no reason to be glued to my phone for 9 hours so I'm very happy with 4-5. Even that's more than I need to be on it.

Well, I got 9.
I normally get 5-6 hours.

You're right no one is ever glued to the phone for 9 hours straight, this was an on and off use. I didn't use my phone continuously for 9 hours. Just saying.

No offense, but I wouldn't call 9 hours of SOT over a period of 12 hours "on and off use". That's great that you got 9, its just unreasonable for everyone to expect that...even 7-8 hours. Yet, after seeing this, many will.
While this is certainly cool, but it's not very useful if it's not reproducible on other phones.
I have one lingering suspicion: your battery protection system may not be working correctly. Usually, a good amount of the phone's battery is set aside to prevent under and over charge. If those limitations were removed, you could get much longer battery life, at the expense of your long term battery health. I'm probably wrong, but just throwing that out there.
On the other hand, depending on how you use the phone, 9 hours may not be exceptional. I can easily get that amount while reading E-books at 20% brightness, for example. (Google Play Books uses almost no CPU). I can get about 7 browsing with Opera Mini (low CPU because page is rendered offsite).
I would have liked to see your detailed battery graph. You can get to it by tapping the battery graph in the normal battery view. The graph will expand and underlay it with line graphs showing what your radio conditions, wifi, etc. are like. So pretty please, if it happens again, please grab a screenshot of that too.
Also, what have you done to you phone? Can you describe your configuration in detail? I can't reproduce it because I'm unrooted, but perhaps someone else can.

None taken, seeing that would make you think so, and yeah I agree I was using my phone for a long time in that 12 hours, but the 9 hours SOT is only because I don't switch off my screen often, like If I am not doing anything on the phone and if its lying on the table or somewhere its on most of the times.
Also, I agree its unreasonable, but if I could find out the reason for this I would surely let all of you know and that would be great, atleast that's what I think.
I normally used to get 6-7 hours SOT, but even if it goes up by an hour it would helpful for people.
Peace.

I have rooted the phone, I have removed some apps, which I didnt want.
Moto features are off.
But other than that I havent touched the system for battery improvements.
Also I have not removed any limitations as such.
This 9 hours was sudden.
After a long usage I realised the battery didnt go down.
So I took the battery reading and also took screenshots.
And yes, this I took a screenshot of the detailed battery graph too.
After this now I am getting 8 hours SOT.
I'll give it to you...that's impressive...especially with your signal in the red the entire time. A poor cell signal is a huge battery drain.
As you can see not everyone uses their this way. He for most of the time was basically on his phone. Average person won't do that. But good to know what pretty much can be the max on this phone
What was your screen brightness set at approximately?
I think chrome definitely serves as a huge battery hog. Don't see that on your charts, so I think it can contribute some as well.

There's no mystery to it you already know the reason you got 9 hours, it's in your first paragraph. When you leave your screen on while your cpu load is basically zero because you're not using your device your battery can last a pretty long time...
People getting 4 hours SOT which is perfectly normal when actually using the device shouldn't be mislead into thinking there's something wrong with their battery life.

Well, that's one usage scenario . Now I know that if I turn off the screen timeout and leave it on a table I can expect 9hrs SOT and 12hrs total runtime. Don't know why I'd ever do that except maybe to start a bragging thread.
I get 4.5-5hrs SOT and 24hrs total runtime in my real life usage on AICP nigthlies. Not great but better than it was on stock LP or MM.

I never said I didnt use my device for long. I said I leave my screen on when I am not using it. But I used the device. Plus my network signal was weak too. That does take a toll on the battery.
Also I didnt mean the reason I get 9 hours SOT is because I leave the screen on, I mean this graph of 9 hours SOT in 12 hours usage was because I left the screen on.
Also I never said anything is wrong with battery of the people who get 4 hours SOT. Everybody including me is saying its perfectly normal.
All was so good,
I was able to hold 2 days with my use (it was incredible, with my s10 I held 24h).
And, then, last update...
And now, in one night of sleep 25-30% of drain ??? Oo
What is that Samsung ? Are you aware like u destroy ur product with this... especially when you advertise about the terrific battery life of the s10 plus ?

I had my S10+ that ever had bad battery life, my s21+ looks like is much better, having 25% of drain in standby means there is an app that is causing that, when you talk about your last update, you should explain which version of firmware do you have now.
My T-Mo USA S21+ gets really great battery life. No change with the latest (AUAG) USA firmware. My S10 got very good battery life (24 Hrs +) but the S21+ (so far) gives me 2 days with MANY hours of screen on time.
Here's a partial dump of a discharge to 10%:
I'm using the exynos variant. I bought the phone on 13th Feb. The battery life is really realty bad for a 4800mah device. I was getting a expecting a decent battery life. But I'm getting like 4.5hrs SOT for 10.5 hours usage which is like half of what snapdragon verison is giving. This sucks. Should have waited for op9pro. Made a huge mistake.!!

I'm getting 2h SOT if I'm lucky, on AUB9.
Really wondering where those big differences between different users come from...

No, that is with Adaptive Motion Smoothness (120Hz) turned on.
I thought maybe my AOD was adding too much Screen On time, giving me a very misleading value, so in one of the tests I made i just played a few movies, and I still got hours and hours of battery life. I have no idea why there is such a variance.
Edit: So I thought of two things to mention. I run my screen brightness at about 35%. If you run yours much higher, that could effect your results significantly. If you use your phone outside a lot and it's set to automaticly adjust its brightness, that could set the screen brighness very high (for when you're outside). Also, I have bluetooth turned off.
2nd Edit: I ran another test last night and I'm surprised to report that there was no significant difference at full screen brightness versus my normal 35% brightness. I had Netflix playing for 3 hours at normal brightness followed by 3 hours at full brightness and the slope of the battery level curve is essentially the same. I'm at a lost to explain this as well as it's been my experience that screen brightness significantly affects power usage.
fwiw
My battery life seems okay but charging is very slow. I've never had so much trouble getting up to a full charge

I use it outside about 2 hrs a day. That too usage. Only for changing the song. Nothing more . I use dual sim .listen to music atleast 1 hour a day via Bluetooth. Even then what you are getting is truly amazing.

I did some tests the other night and much to my surprise turning up the screen from my usual 35% to full didn't make much of a difference.
I'm in the habit of using the "Close all" function in the recent apps screen almost all the time. Maybe that makes a difference?
I'm trying all the scenarios to reach that level of battery life but I go out for atleast 3 hrs a day. So I use my phone in mobile data as well. That also contribute. Yeah closing all applications all the time prevent unnecessary background process. That may actually help in apps like Twitter and Instagram.
Here is the latest I have managed . I removed one of the sim and used carefully . This is the best I have managed so far. But again, I use it outdoors with mobile internet for atleast an hour of screen time. 3 hours of outdoor usage . I'm still not sure if it's a good battery life but I will take it.
As a new S21+ owner I can say that I have had great battery life so far consistently getting 7.5-8 sot. This is with the latest march update.

Watch some YouTube videos on battery optimizations
My battery has been good so far exynos.

I'm using the exynos variant. I bought the phone on 13th Feb. The battery life is really realty bad for a 4800mah device. I was getting a expecting a decent battery life. But I'm getting like 4.5hrs SOT for 10.5 hours usage which is like half of what snapdragon verison is giving. This sucks. Should have waited for op9pro. Made a huge mistake.!!View attachment 5223623

Hi. Looking at your screenshot, it seems you are using an Indian variant. I do not want to get into specifics, but Indian networks are far more congested compared to other countries. So the modem has to work 4 times as hard compared to say the US. Also, dual sims nearly halve the standby time. So the usage you have is fine and I wouldnt worry too much about it.
Have anyone tried disable auto optimize app daily and disable adaptive battery.
Some say it really improve the battery on the previous samsung gen. I'm going to try it. And report to all of you guys.
Just came up to xda to search about anything related to battery and didn't find the solution yet.
Sometime I got a good battery like about 6 hours sot. The other day it just to bad only around 4 hours. It seems auto optimize overreacting to apps and make it closed and open daily causing a worst battery live. And the adaptive battery just seems not good at all in some report.
My best so far today, 10h of SoT doing mostly multimedia stuff. Exynos, 4G, 60Hz, April update. No power saving mode.
