[Q] Battery life

Ive got GN for 4 days use, a screen is hot and battery life is only less than 1 day normal use.
Is your Note have a same? Pls share, worry if need to replace a new Note

I'm not getting nearly the battery life that others are claiming.
I just calibrated my battery this time, so we'll see how it goes.
Please post a screen shot of your 'settings -> about phone -> battery usage' and click on display and tell us the 'time on' numbers.
I have about 2 hours of 'time on' time, and I've gone through a third of my battery. And I have very conservative screen settings. I don't see any way I could get the reported 9 hours of video time that Engadget reported.
I'm not complaining though - on my mytouch 4g, I could get probably 3-4 hours of screen time on a battery. Considering how powerful this phone is, and the size/resolution of the screen...... No real complaints.

P.S. Can you imagine a hyperion extended battery? The stock mytouch 4g battery is 1400, and the hyperion extended is 3500. So a hyperion extended battery for the note would be ..... 6250 mah??!?!? [email protected] What we need is an ibm 'slice' type of battery - that wouldn't add much thickness.

That is too bad, I am looking forward to the phone but was really looking forward to a good day of heavy use in...

Well, I'm getting a good days use from mine with battery still left at the end of the day. And it's pretty heavy use at the moment too.

Battery Life is one of my top priorities, which is why this phone seems to be amazing. I would like to hear from more users about this..

I can't wait until ICS & devs start making ROMs & kernel for the Note. I think then, we will see the Note truly shine.

What kind of battery life test would satisfy you then?

For instance:
I have used a variety of phones over the last 6 months (BB Torch 9800, Torch 9810, BB Bold 9700, Bold 9900, Galaxy 7" Tab P1000, HTC WP7 Mozart) and none of these devices can deal with my pattern of usage every day without at LEAST 2 full depletions and recharges of the battery.
I'm looking to the Note to be the first phone that can last a day, or at LEAST a day with only one recharge.
Engadget reckoned they got 9 hours of video playback on one charge. I do hope that this is indicative of the notes performance...

I am a heavy user. The only battery test I want is if the batter has juice left in it when you are ready to go to bed. I have a 4G Infuse, the POS would die in 6 hours. So lame.

Your post doesn't tell how the battery life is good. The part that consume the most of the juice is the display and I can see from your post that the screen of your Note was awake just for a little time...
So, trying a browsing and video experience would give us a better idea

I can tell you right now just by looking at the screenshot you have something keeping your phone awake. No way in the world is Android OS supposed to be that high. Figure out what it is and you'll definitely see better battery life. 90% positive it's an app you installed.

That's a known ROM/kernel bug in Gingerbread, with AOS taking up so much time. It will be fixed in custom ROMs - though who knows if Samsung will fix theirs ??
Battery tip, if you have NO SIM card in, "cell standby" will tear through your battery in no time. Put it in airplane mode, then enable wifi FTW.

I'm having the same problem. Really frustrating. Needing a recharge every 12 hours or so. And I'm not a heavy user :-/

Dear all,
Today I change a animate wallpaper to static, the result is good, my battery level after same hour, same use is much better.
Before, I full charge at nigh, start use the phone from 7am, web, email at cafe to 8am, have some phone call, email, and web again from 9pm to 11pm.
With animated wallpaper, at 11pm battery is 0, but today, its still at 50%, its good!

Animated wallpapers are battery death unless they are pseudo animations like that melting droid wallpaper which is effectively a giant battery meter. It's like playing a movie constantly.

When judging battery life, you should take in account that if you just have bought the device, you maybe are using it more than you will in the future. (I said maybe, don't jump at me )
I did... And I got 12 hrs or something.... I think that I will manage a good day with it in the future.
Of course the largest consumer of juice will be the screen... So, use a low brightness whenever you can.
And, I bought Juice Defender + from the Market, this seems a good investment and works fine on the Note. (Free version does too)

I can live with a data connection that just every 15 minutes goes on to check mail etc.
(although some people complain when they don't hear from me within a minute )

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 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

Battery should support the phone features.

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.

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.

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.

Possible battery issue

I still need to download GSAM, but I've noticed this over the last couple days. I also have the Gear 2 Neo but I don't think it's causing the battery drain...

A lot of different variables to consider here...same old battery life complaint. Answer, it depends on the operator.

Same
I have the same issue here. The phone had about 30% battery before I went to sleep... Woke up with 1%.
40% is used by Android OS
20% by the Android system
7% by the Screen

The last 2 days mine has been decent, today has been terrible with really high Android System usage.

I should have been more specific, but this is with what I would call "general use". No video watching, gaming, streaming, which, IMO are the real battery killers. It doesn't seem right that you would lose 33% of the battery in that amount of time from a full overnight charge.

All true, but was your bluetooth connected? Wifi signal, cell signal, all the regular shizzle... How does it look for 4 hours of general use with the Gear disconnected?
I'm not asking to be a ****, I'm actually very curious cause I'm looking at getting one

Android System is definitely higher than on my S4, but I don't think it's actually drain, something has to use that 24 of the 100%. I'm getting very good life with about 6 hours screen-on.
That said, it would be good to know exactly what's behind it being so high.
I've also noticed more wakeclocks than normal. I thought it was Google Now but I disabled background data for it and it didn't seem to change anything.
We've gotta get root so we can really fine tune things.

Strange i think its something youre doing. I power use all day from 530 am to 10 pm and i still have 25% before bed

I'm getting incredible battery life out of my S5 so far. Yesterday I checked last night and was at 33%, that's with being off the charger almost 14 hours (like 14hr 51min something like that), on screen time of 4 hours browsing with multiple tabs etc (no games), email, about 30 minutes of phone calls, couple text, and streaming music at the gym for an hour. Today I'm at 72% @ 8hr 31min off charger with streaming music about 2 hours (truck and gym), 45min on screen time, only a couple quick calls. I have GPS etc on, only thing I changed and I always do with Android, is set wifi to stay on in sleep only when plugged in, not sure if they fixed wifi bug Android has always had causing tons of wakelocks in sleep mode.

I'm not sure what I could be doing that drains the battery that much, but I'm not ruling out the watch either... Besides if it was something I'm doing, wouldn't that reflect in the battery usage?

Well, the gear 2 is connected all the time... But I had the first gear and that wasn't an issue. I'll have to see in the morning if it makes a difference. I'm on wifi 99% of the time. I have a Tab Pro 12.2 that's on wifi all the time and that thing is only down to like.. 70% after 2 days of light usage with a bluetooth keyboard connected. The battery seemed great a couple days ago and I haven't changed anything... I've actually done more.. used Google Navigation mostly...

I've had gsam on for the last 2 hours or so... am I going crazy or is this normal?

Give it a charge cycle at least.
However, I just noticed something that is really REAALLY messing with my head. I was just looking at my battery stats again and my phone is telling me it's been on battery for 4 hours 51m. It's 4pm here and i've been unplugged since 6am this morning. My earlier post show's 5 hours even! What gives??? The phone has rebooted once today manually. I just restarted again and can confirm that GSAM resets to zero (whatever), but the issue that's really messing with me is that the system battery and uptime shows 4 hours. WTF?! I'm seriously confused.
Something is fishy here...

I'm gonna let the battery drain completely this time...

Well I've had awesome life since I got the phone last Thursday, like I posted on the 1st page, except for last night. Did nothing different from before, no new apps or anything, I disabled sammy and at&t stuff earlier but the phone was fine after that. I went to bed and it was at 34% and woke up 7-8 hours later to a dead phone. No clue what could have caused that as the past week drain even in standby mode was phenomenal, have to install BBS.
Other night I went to bed and it only drained like 5% in the same time

I fully discharged the battery and it seems better now. But when I plugged back in, I noticed that the app called IM+ was running in the background in push mode... I'm not sure if that was causing the problem but it is much better now over the last couple of days

I had a horrible wakelock today, Directv geniego was running for 6.5 hours. Battery life has been great up till today.

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.

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.
