Serious batttery issue, is this normal?

The battery on my Note is decent, giving me 2-3 days of moderate use or roughly a full day with heavy use.
Problem is when the battery decreases to around 40% & lower, the battery drains like anything even when not used.
Simply idling the phone would lose roughly 5-6% over an hour.
When the battery is around 20% it will easily run down to 10% and less over a period of a few hours when doing NOTHING.
Yet when then battery is at 80 & 90% it will lose around 5-6% battery over many hours.
Here is the proof, I took a screenshot of the battery information & you will clearly see rapid drops in battery life when at 50% and less.
On the last 20% it goes down even faster, and this is with NO use at all.
I hope this is fixed in ICS as it's a serious problem.

Pretty flat at the end there, even while being used.
I have seen that reported elsewhere, but not seen it on my own Note. I have just settled it into a new pattern after rooting and deleting the stats, so I am not certain right now, but I think it remains fairly even over the whole cycle.
I am not sure I could use is as little as you appear to have however!

I've yet to get my Note battery to last until 2 days, and not even a full 24 hours (almost heavy usage on data network).
So I guess that's good enough that yours lasted for almost 3 days!

Haha, don't get me wrong, I think the battery is great.
I'm only wondering why it goes so quickly when it's at 40% and under...

This seems odd. I'd say I'm having the same issue (the poor battery performance).
I've been trying to analyse this but don't have much time to do it right. From what I'm seeing the battery usage graph looks legit. Phone seems to enter deep sleep states. Nonetheless Note seems to drain the battery a lot faster in deep sleep than my Galaxy 3 does, which is odd considering Note having 3 times larger battery capacity.
What seems odd too is extremely slow suspend/resume cycles (e.g. the time it takes for the phone to turn the screen off/show lock screen). It takes more than a second on my Note to show the lock screen. I've seen other report this too. A friend of mine shocked a salesman on a Samsung booth lately when he showed him that. Galaxy S2 is thunderfast, while Galaxy Note takes ages to resume. My Galaxy 3 takes <0.5s. I've looked into the `dmesg` output for some hints. I'm no guru in this, but `ehci` seems to be taking some time to suspend/resume. This also converges with my other observation - Galaxy Note notoriously locks up when playing with usb host. I've tried couple of keyboard/mouse on usb - some of them do work, some of them don't (I can see 'Mouse/Keyboard' connected on the statusbar but there's no mouse pointer nor keyboard input is possible; after some time it's most likely to hard lock the system).
Thus I would suspect buggy usb host/otg hardware/driver that's leading to such a poor battery performance. But hey, maybe it's just me and my theories. Nevertheless something must be broken.

My battery is terrible.
With soe usage, mostly data, I'll drop from 100% to 60% in 3 to 4 hours.
Im on rocket rom.
Only 1 heavy gmail syncing and 3 other gmails with barely an email per week and facebook syncing.
And microsoft exchange calendar syncing (no email syncing).
No twitter.
No other apps.
But im on H+ most of the time.

I know HSPA (H+) eats battery because I turned off my data for 2 days and battery latest me 1.5 days.

I just made a suggestion, that's all. I'm trying to help you save battery. If you want all the bells and whistles and want battery then going for the extended battery is your route. I don't think you will get much more from the standard.

I have had troubles with battery life since I bought this beauty. I have been trying several Roms and Kernels, and none seem to make much difference. I also tried selecting among governors but still no better luck.
When I have 20-24hrs battery life it is very good!
The only thing that allowed me to save some was to reduce lcd intensity, and use the Note in dark environments.
Maybe I am using it more than the average user, but with all the opportunities it provides, I can hardly refrain myself from using it.
My typical use is:
- Radio and surf when going to work and home,
- Email and surf every hour at work
- About 10-20mn phone calls
- Listening to music when I can be alone working (1-2 hrs each day)
- Tablet use when at home.
Do you consider this to be a very heavy usage of the phone ?

I have just had my Note for a few days. The biggest battery eater in my case is WiFi. If I switch it off, the discharge is quite acceptable (a couple of percent during the night). I am not deep into Android internals, but it seems my 5-year-old Palm TX had much better WiFi power management than my brand new Note!
BTW, I am on a stock ROM and have disabled auto-sync.

Have you tried wiping battery stats? Let the phone completely die then charge it without interruption until it's been on 100% for an hour then boot to CWM and wipe battery stats

I do not consider the battery able to cope with the features.
I'm on H+. why wont I have everything auto syncing?
Battery should support the phone features.
Rght now I'm always connected to a power source via USB or car charger or home charger.

I can complain. I paid $750 for it.
The bells and whistles are there but the battery can't cope. Major flaw in battery implementation.
I already told the other guy i appreciate his help but that defeats the purpose of such an advanced and sophisticated mobile phone.
I had a SE symbian for 3 years then several HTC WM 6 mobiles, then a year of HTC Desire then an iPhone 4 for 1.5 years. I'll head towards the best regardless of brand.
Quit being a fanboy.

I am not complaining about the battery drainage per-se.
My previous phone was a Nokia N900, which I used all day long for calls, mails, radio listening, ssh to my home computer, etc... and I knew well that I could not use it for more than a day without charging, sometimes even less.
The phone battery was never advertized as being able to cope with such usage, and only announced battery times for 2G/3G calls.
When I first read announcements about the N7000, I read that Samsung decided to increase the battery power to make it last 2 days, which looked nice to me.
Now I have hardly 13 hours of battery time with my usage (see my previous post) and I want to know:
- is it a normal behaviour for the phone?
- is there a way to make things better with the same hardware?
- do I really need to lower my expectations?
If the answer to the last question is yes, I will be of course disappointed but I can cope with it, as I did with my previous phones. As CorruptedSanity already mentioned, my only complains are to the Samsung techs (or advertizers) and not to any member of this forum who are usually able to help beyond my needs.
I hope that screen optimizations will come that will increase the battery life while I use the phone, but my expectations are low.

You can expect around 5 hrs of screen time based on peoples reports here

Yup, that's the killer IMO. I can leave WiFi enabled all day, or use the phone for a couple of hours of calls and a few hours of 'screen time'. Not both!
Before rooting and killing bloatware, I could do neither.

Milestone & CM7 battery

Hi all
My phone was in for repairs recently. I got it back on the 8th (April 2012) and so I flashed the Vulnerable Recovery sbf and restored my CM7 backup I made the day it went in for repairs. Now, it's been a month, and I'm not sure what it used to be like, but my battery can't even last a day.
Currently I'm sitting on 92% and and took it off charge exactly an hour ago...and since I'm typing on my phone right now, by the time I'm done, it will probably be 90%.
Yesterday, with minimal use, my phone, after 12 hours unplugged, was on 17%.
Should I be concerned? I'm using CM7.1.5.
Sent from my Milestone using XDA App

actually dude... i also noticed that as well.. cm7 really drains the battery quick...

I need to know what you all are experiencing. It's just a few minutes shy of 12 hours since I unplugged. And apart from two 1 minute calls and updating 4 apps on the market, I barely used the phone (only checked this thread about 4 times on the XDA app). It's now at 14%. It's a bit worrying, because I'm still on my way home, and it's almost like I can't manage a day at work without needing to charge. And I don't carry a charger or USB cable around most of the time.
Please give me your inputs. I know this is a fairly common problem to hear about, but I'm sure my CM7 experience could be better. Ps, I have calibrated the battery. Mostly keep EDGE on instead of 3G if I'm not really using it. Also, never have the GPS on, nor WiFi, nor Bluetooth.

The milestone never got a good battery life. Since my gf had it new, she cant make a day. (she's not a "phone" girl, she use it for txt/call, thats it).
Around 25%, you have about 3 hours on sleep. if I use it, it will drop to 0 very fast.
The phose is a year and half old, 2 battery rotation and froyomod 2.9.3 rom.
And for the same time of use, my desire z can last 2 and a half easy.

I have a mugen 1700 battery (same size as the original one but 20% more power) and I can use my phone for 24 hours without charging (even if I usually charge it during night even if not completely discharged) .
I use 3g with toggle2g enabled, Facebook, whatsapp and other common apps and Widgets, I have autosync fully enabled, and I play games do less than one hour per day.
Maybe you should try a different battery

it's a good battery, but for the today MS quotation, it's like half of its value..
I've bought a DEJI 2000mAh for a bunch of euros, but honestly 2000mAh is just the nominal power, it lasts like the stock one..

um, what?

My phone is now one year old with stock battery. It's has a decent battery life, with toggle2g enabled, full autosync with Facebook, Path, Twitter, Whatsapp, Google+, Dropbox, Gmail, I get about 12 hours with moderate usage.
Brightness is fixed at max.
But it is unstable. Some days my battery will last for 12 hours, some days it's at 15% in 5 hours.
I dunno if it is CM7, but sometimes the phone has dificulties in syncing and it does get really hot.

To me, the stock battery is too hot, and keeps discharging faster the more hot gets. My mugen never gets that hot, and never fluctuates that much in duration

Oh yeah, I notice that too. when you use the phone, maybe 5 minutes later, the phone is hot.
One other thing, the milestone can charge 20% to 100% in an hour. its really fast, and its not very good for a lithium battery since it comes very hot.
what are your average charging time?

I would assume this isn't your daily phone anymore? You have no usage by texting or calls. Sure, you got 5 days standby time, but that's literally on an unused phone.

actually, you should leave it a bit more in charging state, to avoid internal counter fail. That said, yes, the battery is rather fast in charging. I really suggest you the mugen battery, that's fast in charging but slow in discharging

Hmm, going through all of this, my usage doesn't seem too different to you guys. Maybe I should just get used to it. I actually did buy a spare battery off eBay - but it's just another BP6X battery. I think I will try this mugen battery.

Hello d.casper.b. I upgraded to CM7.1.5 (from stock Eclair) in Jan 2012. Since then I have a bit better batt life. Standard battery. I unplugged my phone yesterday (Sunday 15th Apr 2012) at about 12:30 - 1:00 pm. It's now Monday 3:10pm and I'm at 50%. My wifi is on all the time, except I turn it off when I go to bed so it don't wake me up with email or whatsapp messages. I don't have sync on and my phone is not on a data service. I have only used it for some light browsing since unplugged. No music or streaming data. No screensavers. Auto-brightness. I will use the bluetooth when driving home from work. That said - I typically get 24 hours+ on a full charge - except if I do some youtube or other streaming stuff.
That said - I don't think the ROM is the issue. You should try a battery calibration. Also - when it gets to 100% charge, leave it for at least 15-30 mins more plugged in.

Please stop suggesting battery calibrations. I really don't think anyone has a clue what they're talking about when they suggest it.
What you all call "battery calibrations" doesn't do anything other than make Android forget how the battery has been used -- that means the USAGE STATS. It can take a few charge/drain cycles before the battery meter reads true after that. It doesn't do a damn thing to your battery life.

destruct2k sorry - but no need to get hot under the collar about it. But in a sense - you have a point about the batt cal. It's been suggested on other threads - but I've never tried it - and so I shouldn't be recommending it to anyone. I only repeated what others had suggested some time back. Peace.

Anil - You're right, I overreacted there, but not too long ago I saw a 3-page article posted on Google+ by a woman that works on Android for a living about how "stupid" (her word, not mine) the concept was that deleting a file in software could somehow affect the battery's ability to hold a charge. Ever since that read, my opinion on "calibration" has changed significantly. If I could only find that article...

I have the same issue. And it's kinda strange because it's only comin up with CM 7.2
The worst battery life was 30 minutes. I charged it to 100% and I went for a walk before I went to my dance class to teach and after 30 minutes it's drained from 100 to 13% and I did nothing just listening to music. Weird. And when I charge my battery it's like going to 20% like in 5 mins and then 2 mins later it's on 60% and then 40 minutes later it's charged...I'm tryna find a solution for it cos it's soooo frustrating and I don't wanna change my phone til Milestone 4 is coming out!

Battery Life?

Yeah yeah I know its got Stamina Mode BUT! is anyone a little worried like me that the battery is 2330 and with a 5 inch screen and all those pixels its going to drain pretty fast. Todays phones with 720 screens and less pixels aren't the best. I'm still getting the phone but anyone else think we aren't in for glorious battery life here. (Stamina Mode may be the perfect fix for this though)

im hoping we get some battery reviews in soon. i have yet to see any real in depth reviews for the battery yet.

Yeah, thats the part of the reviews I will be taken proper interest in.

Coming from the One X, I'm not too worried about battery life as I'd be fairly confident it could last a bit longer than that phone. I charge my phone every night so once I get a day out of it thats fine.
I would like to see a review on the battery life though.

2330 AMH is really good though

I have 3100mah on my Galaxy Note 2 right now. Pretty huge battery - was supposed to last 3 days - it barely lasts 48 hours of "normal use". Not worried about Xperia Z, if 3100mah can't supply more than 5-6 screen time or 48+ hours - no battery will. If it lasts 2 full days, i'll be more than happy.

From what I've heard it's actually surprisingly good. Keep your brightness in check and you'll be fine. Both the Snapdragon S4 Pro and the MDM9215 are pretty efficient chips. The S4 Pro has (according to Qualcomm at least) a pretty high performance per watt so should do pretty well with relatively little power use.

From the 1st review:
"The Z’s battery-saving Stamina mode turns off data when the screen is off, boosting standby time by a factor of four, and we found it hardly lost any charge overnight – around 1 per cent, or none at all."
Now that's interesting.

Early tests not so encouraging. Worse than the nexus 4. Of course screen brightness etc aren't known at this point.
Let's hope it gets better with more charge cycles etc.

Doesn't look too good. 9 hours with 3h screen time... but the screen drained 42% of the battery so i guess it must have been under some heavy stress. Hope to see some more tests/reviews asap.

yeah, all we can do is wait for the NDA to break. I really hate waiting.
hope the battery's up to scratch because i haven't been this excited for a phone in a long time.

When do nda normally break? Seeing as it should release in some territories in a few weeks, I'm surprised there haven't been more reviews. Hoping to see some from the big sites any day now, especially the verge, gsmarena etc, as I'm really interested in battery life. Would need about 3.5 hours screen on time on mid brightness on 4g over say 15 hours off charger to work for me. Guess I could make do with 3 hours, but whichever of the new 5 inch phones does this will get my money. Come on Sony, don't disappoint me, cause I love the look of this phone!

A) reviews take time
B) It seems as though the CES units were not final... so the final product may not have been available until very recently.
Sony stores/reps are starting to get their demo units (which should be final hardware) so hopefully more reviews soon.
BTW NDA is usually to keep the details of the product hidden until Sony is ready to release. The phone has obviously been officially announced so this is not an NDA thing, just the fact that they don't want reviews done on inferior pre-release units.

And by looking at some threads here - it's perfectly understandable. People freaking out about things that are not even present in the real device like older software, lower benchmarks due to debugging firmware etc. But i'm really dying to see the battery life... if it's non-removable and it won't last 48+ hours of normal use, than it's not good. If it won't last 24+ hours of normal use than i guess i might reconsider ( and by normal use i mean texting, calling, maybe some music - not playing with it every second, that's reserved for few first days )

That screen shot over page with 9hr 33mins battery life. I didn't see the sign for power saver/battery saving mode being used. I mean surely the phone has to last a day atleast under moderate usage. I mean it has a bigger battery than the S3 and that lasted over a day on moderate usage and the cpu in the Z is supposed to be more power efficient is it not.
I also think battery life is a subjective matter for example me and my GF both had the note 2 and I set her phone up exactly how I set mine up with the brightness etc and she was getting 4days - 5days 20hours battery life and mine was getting 1day 20hours - 2days 23hours, why? because I use my phone a damn site more than she does and the variation is because some days I use more phone more than other days so some days the battery will last more and some days it will last less.

Well that's not reinventing the wheel, most battery saving apps like Juice Defender do that. However I need a stable IMAP connection and not fire up the screen constantly to check emails.
There is nothing special in making the phone last longer with software trickery, it's like making yourself last longer through thinking about your grandma.
A good battery and battery efficient hardware is needed.

Juice defender kills apps but issue with this is apps relaunch itself and then juice defender kicks in and kills it again and ends up in an infinite loop of killing and reviving of processes. The difference with stamina mode is that it was officially made by manufacturer within the ROM. So when you set it to get killed when screen is off there's something within the framework of the android core which they programmed to really halt the operation of the app/process and not just killing it. So in the end it is totally stopped

The thing with the S4 pro is that it can go both ways as far as efficient hardware is concerned. I think it has something to do with thermal insulation.
The nexus 4 and it's 2100ish mAh has notoriously poor battery times - in my testing, tapping out at just under 3 hours screen usage in around 8-10 hours of total use (everything stock + 4.2.1).
My padfone 2, on the other hand, with the same battery/screen size is a battery champ - regularly get 5 to 5.5 hours screen usage over a period of 18-20 hours. It beats out all my previous phones for battery life (minus the note 2), including the GS3 which had good battery life itself.
And no, i don't belive in disabling google now and push notifications. Without them the nexus 4 does better but the padfone 2 and its s4 pro do brilliant with them on.

No argument here - although if it actually does work - then it's a welcome trick. Juice Defender - imo - is useless. It never saved any battery for me - quite the contrary, constant app killing in the background resulted in worse battery life on my Galaxy S/Note devices, so i'm curious how will Sony implement such a feature.

Why would you guys use JD for killing apps? That doesn't make sense. Its main use is to manage radios etc. depending on battery & screen status. Anyway didn't do much for me so switched from that to Tasker.

Not getting this "awesome" battery life??

Hey all. I just got my s6 active via insurance upgrade about 5 days ago.. I expected more battery from what I read... I unplugged it this morning at 525 and by 625 I was at 92%. Is this normal? The battery screen doesn't add up to the battery % lost. I'm just trying to figure out how everyone is getting this great battery. Is it possible they sent me a referbed with a used battery? Many days/weeks of running the phone will it take in order for the battery to even out?

Seems like your phone doesn't go into deep sleep. There is a rogue app that is probably causing your phone not going into deep sleep. Find the app cure the problem.
Yes it does take many cycles for the battery to reach optimal battery life

Nothing keeping it alive.... Cpu sleep time is the majority of the time. I do use my phone heavily. But i get about the same life as I did with my s5 active..

Same here. I "upgraded" from a 6S on the premise of much better battery life and waterproof without the need of a LifeProof case.
So far I'm getting about the same, maybe less life out of it than my iPhone. I've been out of the Android game for almost 2 years, what can I do to fix this?
Based on battery tests and whatnot, I should be losing around 6-7% per hour, instead of the 10-12% I'm losing now, about on par with an iPhone with half the battery size.
Any help is appreciated.
EDIT: Noob mistake, forgot to mention I'm on the forced 5.1.1 version.

The 5.1.1 version was a battery hog for me too. Before it, i would make it til bedtime with about 30-40% battery of moderate usage. During the 5.1.1 upgrade i was at 40-50% before lunch! Had to charge twice daily. Now with Marshmallow, i'm back up to all day battery. Even lately being a heavy user, it'll generally last all day. I might be at 5% by bedtime, but it'll last all day.

How much SOT do you get?
I lose about 6% per hour if I watch videos on wifi, however I lose 1% every 6-7 minutes if I'm using my phone for anything else.
What system process is killing the battery? There's no reason I shouldn't get over 12 hours of SOT from daily usage.

That's what I'm talking about. I used to freeze basically all non vanilla processes back in the G2 days with Titanium Backup, how can I freeze the Exchange server? It doesn't show up under "Applications" in settings.
Currently on 6.0.1.

I don't know how to say this without sounding condescending, i don't mean to, but you're insane if you think you should get anywhere near 12 hours SOT. Let alone "no reason I shouldn't get over 12 hours of SOT". I doubt I could get 12 hours SOT with 2 batteries.
I average 5-6 hours SOT which i think is actually pretty awesome, (And that's with the dark theme). I honestly don't count battery percentages and compare videos to surfing/browsing. I just know that i can use my phone all day and I don't have to charge it until bedtime.

Their web browsing test is a more realistic expectation, which is why I said 12. They got 16 hours, which I don't doubt, but this phone draining comparably to a 4+ year old HTC? Not at all impressed.
I have screenshots where I tested their results vs actual daily usage and they were very close for every phone.
But no worries, I'm glad you're satisfied with your phone's performance.

What web browsing test are you refering to? I'd like to run the same test and see what i get. Almost nobody gets over 6 hours....
http://forums.androidcentral.com/sa...-how-much-screen-time-you-getting-charge.html
A few new phones have come out with massive batteries, but still not 12 hours SOT. One guy with a 10Ah zerolemon on his note 4 was able to get 16 hours (unverified), but that's the best i've ever heard.

http://blog.gsmarena.com/samsung-galaxy-s6-active-battery-life-test/
The One X, S3, LG G2, and iPhone 6 & 6S web browsing results were great representations of what I could expect as far as smartphone battery goes. I've had more phones than I can count, but those were the ones I kept the longest and remember the results off the top of my head.
I can find my old One X SOT screenshots to further prove my point.

This makes no sense to me. In their test, the battery lasted longer playing videos, than web surfing? Something is off here. I've never seen a phone have more than 6 hours SOT, ever (with the exception of extended batteries). Maybe if the phone was in extreme battery saver mode and the screen was at the lowest setting possible, and it was only on 3g, it might be possible to get 6 hours. I'm not calling you a liar, or the article you posted a lie, i just have to believe something else is going on. If i was to get 12+ hours of SOT, for me, that would be equivlent to the phone lasting me all work week.
I hope you get your battery life figured out, but i have to believe we're on different pages here about something. There was an update pushed out this morning, maybe it will help a little.

Yes, this is due to less CPU usage and videos/movies are not almost entirely white.
I looped a couple of YouTube movies and left the S6 Active running all night at 50% brightness with only wifi on. I woke up, 8 or so hours of SOT, and the battery has 59% left. This leads me to believe it's a system app, more than likely a Samsung one, since all of my other Android phones don't have this issue.
I'll post up actual pictures when I get home, I'm back on my iPhone.
You haven't been here long, which is fine, but trust me when I say that there's something draining the battery. A G2 with a 3000mAh battery lasted over 9 hours consistently with data on, the S6A should have no problem matching that.

Hello I have recently purchased an used S6 active gsm unlockrd with android 5.1. This is my first day with it I still don't know about the battery stats anyway I would like to know if I will get improvement in marshmallow. What are the advantages. Also since at the s6 and s6 edge the marshmallow update improved the camera speed. I would like to know if it will improve also the camera speed. Thanks

Hmmm, maybe i'm just considering real world use instead of ideal conditions. Kinda like how i'm supposed to get 35 mpg in my car, but actually only get about 26-27.
When i was on 5.1.1 and had insane battery drainage, all of my research and testing said it was kernel related. I just stuck it out and waited for marshmallow, and now my battery is back to acceptable to me.
Keep us updated if you figure it out, even though i'm relatively happy with my battery life, i'm always happy to get more.
P.S. I've actually been here longer than you, so i'm not sure if that was directed at me. You are way more active and most likely way more software savvy than i am, but i've been here a long time.

Yeah he gained 9% battery by leaving his phone on all night, lol. I kid, maybe i'm just reading it wrong.
"left running all night at 50% battery life....... I woke up, and the battery has 59% left"

I meant brightness, too many ideas at once haha. I'm posting actual pictures in a second, and will keep the phone running while I'm at work.
It has to do with a Samsung "feature", I've turned off most of them from settings. Next will be disabling packages.
It sucks that we don't have root, it seems like an AOSP Rom would net us the battery life that we should get.

battery life

Hi guys. I just bought my phone today installed all the apps and then fully charged it. However I am getting poor battery life. What is causing my battery to be crap? I don't see what the issue can be as it is a brand new phone. Coming from the sony xz premium i feel as if its a downgrade on the battery end of things. Does anyone have a suggestion

I thought my battery was terrible at first when I got it. I noticed lately I have not noticed so much anymore. Right now phone been on for 2 hours straight and lost 25% with brightness half way. Just give it time

It scares me that battery life is not going to be any good and I have to hunt for the charger through out the day. With my xz premium with about 4 hours usage i normally had 40 to 50% remaining. I don't want to think about charging my phone just to get through a day. Lets just wait and see if it gets any better

Android needs some time to adapt to your apps.
I bought my Note8 three days ago and don´t used it permanently respectively don´t have so many apps installed.
I charged it 2 days ago (at 18 o´clock it was fully charged!), now I have 48%
Before I bought my Note 8 I had a Mate 10 Pro with 4000 mAh and 60-70 apps. Android needed 3-4 days to adapt. In the first days I had to charge every day. After a week the Mate 10 Pro had to be charged only once in 2 days.
So do not worry!

Watching this with interest. Mine is a week old and I feel like I need to keep topping it up. On the road all day today and worried she won't make it!
I've a charger in the bag. But going to see how far I get!

Thats what i was saying while i have the chance i might return it and get the Pixel XL 2 or the mate 10 pro. I believe both have better battery life. The pixel loses out on screen quality but makes up with software and battery life. The mate 10 pro loses on software but kills it on battery life. So tough choice to make. However i can't stand poor battery life especially never having to worry about battery life on the sony xz premium

Had mine since day one and the battery gets better the longer you use it. I have several things disabled that are big battery suckers - Bixby for one, don't want or need it. I can go 1-2 to days of moderate use, using an ereader app but no game playing.

The better question is, what apps did you install? You need to just use your phone for a few days. It will begin to background/sleep apps you aren't using which will extend your battery life.

Like myself and others have said, just use the device. You're comparing a device you used for a period of time to a device you just got just over 24 hours ago.
Those apps are considered battery hogs because they don't sleep. Also, Xperia devices have a sleep function implemented. They were the first ones to ever have such a robust background sleep function of Android devices.
The sleep function should be on automatically during setup but it could be turned off. Look under battery settings and it'll be there with the option to turn it off. I recommend keeping it on.

Yes i will give it a week and see if it settles. If not by hy note 8 and hello next phone. Lets see what time will show

Not sure where the setting do turn sleep on and off is, but the phone has sleeped (is that a word?) a bunch of apps. Battery is looking good so far today.

There was a video showing ba they life from a s8 a s8÷ note 8 and the late. And the note 8 lasted 2nd best.

I've disabled knox, security folder, bixby, ant radio all the t-mobile apps, several of the edge screens and a few others.

As others have pointed out, the device needs some days and several charging cycles to achieve a good performance, besides, and very important, in settings>device maintaince>battery, there are 2 groups of apps that you can choose, always sleeping apps and unmonitored apps, there you can control their behaviour

Yeah some of the Samsung apps and services being disabled will actually cause more drainage to occur.
