Battery DRAMATICALLY Affected by Brightness

**PLEASE READ THE TITLE**
This is not a general battery life thread. I'm looking for comparisons of brightness levels. Thanks.
ALSO: Has anyone noticed a difference when using black themes/wallpaper, etc. I have NOT noticed any significant difference.
Ok, first off, everybody knows brightness affects battery use. However, I've been trying to run my brightness at 30%, which seems pretty low. I figured that can't use much more power than 0%. Still, I've only been getting to about 2pm after charging my phone all night. I'm a heavy user, I like to tinker with my launcher a lot, check facebook, texting, etc.
Today I decided to try 0% on the brightness setting. I'm not crazy about this since it's not bright enough for most situations. I mean, I bought a SAMOLED+ phone for a reason. Anyway, the battery usage seems to be DRAMATICALLY less than with 30%. What's even more odd is my battery usage shows my display using 40% of the battery instead of 50%, which is what I normally see. This isn't a very significant change.
So what about everybody else? Are you guys having the same experience?
UPDATE: I'm up to 7 hrs now and have 67% battery left. Screen on time 1h 26m. This is a dramatic improvement still from 30% brightness.

Ive had my brightness at 100% for most of the day. Im getting great battery life. Im a heavy user and I can get atleast a 1 1/2 days with a single charge. Luckily I hve the luxury to charge over night.

You sir are not a heavy user if you can get 1.5 days with a single charge on 100% bright.
Or maybe a heavy user on calls not browsing or things that use the screen.
on 100% simply 1h browsing, 1h with video, 1 account sync, texting, some calls, check twitter and fb will kill your battery in less than a day, and that is not heavy using.

Can i ask how many hours you have your screen on,
because with 100% brightness i'm lucky to get 3.5 hours (internet/games/twitter) of use out of my phone.

copy and paste from another thread I posted in. This is a very typical day. Now I dont use my phone as much after 6. My phone is currently at 30% from a full charge from friday night.
I make it during the day with 100% brightness. I consider myself an a heavy user.
Ill show my usual day after the new factor wore off.
Unplug at 630-7am
Start my music through Poweramp around 9am at work.(20 gigs of music)
about 20 text/ 30min total of calls
20 or so emails with some attachments
Usually download about 200mb of music/videos throuhout day
Check about 10-15 websites every couple hours(xda app most frequently)
Use Logmein about 10-15min total
Play LIVE holdem Poker roughly 30min total
Youtube/video watching
Some other random things I cant remember
3g/h+ on all day
wifi stays on
brightness at 100%(bright orange/blue wallpaper)
Browser brightness is at 50%
Everyones experience will be different. My original Samsung galaxy s(vibrant) would be dead around 5-6pm. My Galaxy s2 is around 40-50% around 5-6pm. Im experienceing great battery life. My fiance iphone4 would kill my vibrant in battery life, but the sgs2 is on par.

Yes, I too find this very hard to believe. I know if I watch a high quality video on YouTube the battery drain is insane. Of course that is data also but I doubt I could get an hour. My guess is if I just left the screen on for 2-3 hrs my battery would be dead from 100%.

Nope, that's definitely impossible.

I don't believe you, period.
On my s2 I lose 30-40% in 2 hours of not very heavy use on auto brightness. I am shocked that when I surf I can see the battery number (using battery guage) actually ticking down. Device is nice but battery life for me makes it totally useless for a prime device.

I've got display at auto-brightness which is usually around 30% for me indoors. Got display on time of 4hours 16minutes..includes about 45minutes of 3d gaming (modern combat 2) and rest browsing/downloading etc..
total up time 12hours 39minutes...and got 22% left...thats incredible to me, coming from a desire hd, I cant believe my phone is actually still running haha..
EDIT: Oh yea forgot to mention, I got a new replacement yesterday which means I havent even gone through the charging cycles yet, my previous one was superb aswell so fingers crossed this one will be too

Im off today so my typical use is different. Ill repost my battery stats when I get home after work tomorrow.

Well this is helpful, thanks. Sounds like you are getting better battery life than me. Although I would say I definitely am a "heavier" user than you. I used to make it to about 3pm with my GS1. I'm getting about the same with my GS2 if I leave the brightness on auto. That's if I don't use YouTube for more than a few min. I too would like to know what your screen on time is at the end of the day.

Sorry, posted this in the wrong place

That use and that battery it is simply a lie.

The screen is definitely a battery drainer. Don't set the screen to 100% brightness and record 1080p videos. Battery level will be at 0% in less than 2 hours.

Why the f would I lie? Samsung is not paying my bills nor cutting me a check. ill post tomorrow after work my battery stats.

That is impossible on THIS phone with THIS battery! Period!

I'm waiting for those stats.

A screen shot of his display on time along with the graph is what's needed.

Can we get back on OP's original topic of display brightness vs battery life discussion, this is a topic I'm interested in as well as I leave mine on auto-brightness and display is always #1 on my battery consumption list.
Maybe intruda can start a thread called "How my battery life is superior to everyone else's SGS2" and the dissenters can go there and call him out. Just sayin'.

This is my usage today with auto brightness. Mostly at 30%-40% brightness with 45minute gaming and rest browsing. Music. Youtube.
Im impressed.

Galaxy Note 8 Battery Life

After 2 weeks of using the 3G version of the Note 8 (GT-N5100), I could say a full battery charge gives me at least 7 hours of actual screen time for a 16-hour stretch for the day, using it for light to medium apps and social network sites. I also do drawing using Adobe Photoshop Touch, Autodesk Sketchbook Ink and Sketchbook Pro.
This is my first tablet as I think its compact size and weight is more ideal than the heavier Note 10.1. I simply love digital drawing with the Note 8. I'm coming from a Note II and the bigger screen just gives me more area for line strokes.
7 hours of actual screen time isn't a wow for me as I do my torrent downloads with my Note II with also the same screen time and be able to change to a fresh battery usually in 12 hours. I just find plugging in the Note 8 in the late afternoon to be confident that it really doesn't die on me for an evening in a cafe.
Some 80% of the charge goes to maintaning the TFT screen! Is this normal for TFT screens to guzzle up that much power? I set my brightness to 30% and even set it to power saving mode. Still the screen is the main battery drainer.
Anyway, I set up this thread in the hopes that people can share how to best optimize the battery with proven sound practices.

My Note II only takes roughly 30% of battery charge usage. I'm guessing AMOLED is just more efficient than TFT screen.

What I noticed... the time shown in battery statistics seems to be wrong.
I was also getting approx. 5 hours on battery according to battery statistics. But this felt wrong for me. So I fully charged my Note 8 -> Usage statistic showed 0 hours. Then I was playing and reading for 2 hours (display always on, no reboots). But statistics where showing something around 1 hour and a few minutes. So don't trust your device.

Screen on time tells only part of the story. Its what you're doing with the screen that matters. Browsing and videos will drain the battery faster than reading a book.

Thanks?

It also depends on what apps have sync/auto update features turned on. I used my Note 8 on Mothers day to watch movies and I was able to watch 3 full movies and still had 30% left. Beanstown will be posting a rom soon and battery life we only improve.

That's normal. I sometimes get 6 hours+ screen on, other times with 7 hours screen on time. I have yetto serif this baby can make it over 9 hours screenon. I'm trying out Greenify app as it hibernates apps from wake-ups to sync. I'll let everyone how it's working out in a few days.
Still, the majority of the power would still go to the screen. Having a dark theme wouldn't help as the ambient lighting would still take the same amount of power. It's there a way to turn off half the LED lights? I really wished the screen is really Super AMOLED for energy efficiency.
I still find the Note 8 handy as a sketching device.

Point being that if you get 6 hours of screen time and I get 9 hours of screen time, doesn't mean that my battery life is better than yours. I was at 8 hours screen time at 25% battery last night, but I'm not going to say that this is average for me. Depending on my specific usage, I can get anywhere from 6 to 10 hours of screen time. This is why user reported battery life must be taken with a huge grain of salt.

I dozed off and forgot to charge my Note 8 last night. My stats below show a 24-hour unplugged use with phone, wifi and bluetooth on. I had used my Note 8 with 4 hours of screen on time with just Chrome browsing, a few minutes of S Note, and 5 22-minute tv episodes.

I still had 35% of battery left. I use Greenify to have my wakeups off when screen is off. It also hibernates apps if you don't activate them, like my Facebook doesn't update unless I check.
The screen still is the highest consumer of battery reserves at nearing 80%. I usually have auto brightness or keep it at 30% bright. Is there a way to reduce the power consumption further other than tune the brightness down?

Also, take a look at Civato's kernel in the dev forum. To install it you need to first install Clockwork (I used Odin for that), then boot into your new custom recovery and flash the zip file.
The kernel supports underclocking (down to 100 mhz at cpu idle) and undervolting as well as a ~20% overclock and some other very nice features.
It's been stable for me using a 75 mvolt underclock, and I use some governor tweaks to avoid spinning the CPUs too hard when they're working on "nice" processes.
My battery life is often in the 9-10 hour range.

I have One Power Guard to lower the CPU with its governor tweaks.
Is it 9-10 hour range of screen on time or just the device use per charge?

9-10 screen on. And my impression this weekend was that if I leave wifi off, longer than that.
Most of my use is evening, so minimal screen brightness. And probably 70% reading, rather than primarily videos.

Good. I carry my Note 8 as a secondary device with my Note II as my primary device for communications and downloading torrents on the go. When I do need a bigger screen, I transfer media via wifi-direct. The 8 pretty much is my drawing tablet and productive tool for thinking through sketching architectural ideas. I still switch to paper for permanent recording on my sketchbooks.
8 hours isn't that good for me. I wish the screen consumption shouldn't reach to 80%.
rooted stock Galaxy Note 8 GT-N5100

I've found the battery life to be much better than anticipated. but since i've mostly been using away from home, I've had all the connections turned off and when I am at home I have auto airoplane mode activated that turns off the connections when the screen is turned off.
I also have been using the power saving mode at all times other than when playing graphics intensive games as I have no need for intensive CPU usage when browsing, drawing or taking notes etc...
Im hoping that when I root and add some custom profiles my batterylife will improve further.

I had the time to test out the Note 8's battery life on a continuous usage with mainly browsing, note and sketching with the S Note for 3 hours, about an hour's with of video watching, wifi and bluetooth connected. I've had 7 hours of actual screen on over an 8 hour period, from 8 am to 4 pm with 5% of battery left. I didn't want to fully drain it to avoid ruining the battery charging capability.
I had the screen at only 20% brightness with phone function on. The battery could be easily be drained in about 4 hours if with a brighter screen and heavier processor based tasks like games. The screen still ate away 80% of the battery charge despite being toned down to a 20% screen brightness.

[Q] Dear Note 3 owners, what do you think of the battery life?

Hi guys.
I've had the Note 3 for some days now and I gotta admit, I'm having a hard time getting thru one day with heavy usage. I went from my Galaxy S II which held an entire day with moderate usage(with custom kernel+rom tho) expecting to never, ever worry about battery life no matter what but the truth is, that it is much harder to get thru a day now. I dont know if it's my phone or just a general 'issue' but I expected it to last much longer than it does.
**I've done a few test as you can see here**

Reinstalled, no wifi, no gps, no bluetooth, automatic brightness and went to bed(it was at 98%):

Woke up, used it for radio(downloaded TuneIn for radio) + news(aka Reddit News) while eating, for one hour. Still no wifi, gps, bluetooth and automatic brightness on
http://puu.sh/53k1C.png
So it ate 20% battery on 1 hour with radio + Reddit News. Used the phone the whole time, screentime was 47m out of the 1 hour.
---
I just reinstalled everything, again, and did another test. Havent touched any app at all but YouTube. Wifi and GPS were on as default and didnt touch that. I opened YouTube and played a 2 hour movie with auto brightness and 50% media volume. This was the outcome
http://puu.sh/53jUQ.png
The red line shows when the video stopped. So it drained 20% battery on 2 hours.

What do you think of this, how is your battery life and are you satisfied with it?
I'm wondering if I should send mine in for repair, but I dont know if its my device or just pretty normal of a Note 3...

I have bad battery on mine too

Phenomenal battery life.
My S4 would be dead in 8 hours whereas N3 has a good 40% remaining.
I'm not rooted.
I'm on 4G & have medium to heavy usage.

I have very good battery life (with auto sync, data & wifi always on, etc...).
But I did some actions: root -> Greenify all apps which do not need really background interaction.

Turn down the screen brightness.
If I watch a video for 3.5 hours on full brightness it eats 45%. Same parameters but with brightness at 30%, it uses only 19%.
Also, get rid of Touchwiz.
I'm quite pleased with the battery life. I unplig at 100% at 2200, get up at 0440 (ah the joys of Public transport...) and when I get home at 2015, it'll be around 40%. I religiously check the railway planner every 15 minutes, email every 30min, take notes and watch films.
That said I did buy a 15600mah powerpack. Public transport is not know for its reliability here, so I need a backup plan. Particularly with the oncoming annual apocalypse dubbed 'snow'.

It's not bad so far. Though I haven't been keeping any real track of usage and battery stats so far. I'm only on my second charge, and I've been tweaking the phone to my liking and installing the X-NOTE ROM. After this initial tweaking and fiddling period I'll get a better idea about the battery life in day to day usage.
I come from a Note 2 and so far I'd say it's about the same.
I read a post by X-NOTE developer soloilmeglio where he said that the stock kernel for new firmware version MJ6 seems much more tweaked for battery life, so that sounds great. I'm on MJ3 now, waiting for his MJ6 build.

During the first 10 days I was disappointed (I previously had a s3). But now after several refills I'll say the Gn3 battery gives about 40-50% more autonomy than the s3 did. From my experience it's a good thing to charge only when you reach 15% and to run a full charge without using the phone.
Currently with a full charge and a heavy usage it's ok for two days. Most of the time I reach 3 days. That's not far from 1 more day than what the s3 did.

I bought this device last Thursday so it's been 9 days now. I need to probably spend another 10 days.
I have to say, as a power user, I'm not very impressed yet. Coming from an S3 (3G), I expected a significant "road warrior" bump but I'm just lasting a full day. When I heard reviewers going on 3 day weekends where they used the Note 2 and it lasted easily 2 days, I expected the same with the Note 3.
My work day is 0600 - 1630. With my S3 in moderate/heavy usage pattern I got home with maybe 15% remaining. With light/moderate usage, I'm home with 30%.
With the Note 3, my moderate/heavy pattern gives me 25% battery remaining for home. Haven't done light moderate yet. Estimate maybe 45% battery will remain.
In both cases we're talking about 3.5 hours on screen time heavy usage. 1.5 hours light usage.
Of course it should be noted that I'm comparing a 3G device to a 4G device. Also, EE 4G in London seems to have pretty week mobile signals or the Note 3 just has a meek radio. I'm really hoping that this improves after more charge cycles and/or updates. I want to be able to have a average screen on time of 4 hours and still go home with 35% remaining so I can still use the phone for the rest of the evening before bed.

Reading your message I realized I forgot to mention I'm only using 3G. This may affect the results as 4G eats more.

I am having the index service issue. My S II had better battery life.

Mobile network data (3g/ 4g) uses more power than wifi. Use ur home/ office wifi and save power. Before i bought note 3, i thought the battery would b great. But its OKAY.

Just wanted to update:
So I did a few testing sessions and have come to the conclusion that my biggest battery drainer for me: Auto Brightness.
Now after 2 days of setting the brightness manually (roughly to 15%) my battery life has definitely improved dramatically.
I'm getting over 3hrs screen on, heavy usage with 40%+ remaining at the end of a work day.
Today, I've had almost 4.5hrs screen on, heavy heavy usage (a lot of 4G, played the new free Asphalt, huge amount of web browsing) and the phone was at 5% before I finally charged it around 9pm. Not bad considering I had 4G, Wifi, GPS, NFC and Auto-Sync on all day today and listened to almost 1 hour worth of podcasts on my commute so the device was awake for a long time.
I suspect manual settings of brightness at 25% would give pretty good battery life as well but not necessary when you're indoors with lights.
Maybe still not a 3 day phone I think but with [my] light usage it will definitely be a 2 day phone.

Mine is great

Reinstalled, no wifi, no gps, no bluetooth, automatic brightness and went to bed(it was at 98%):
http://puu.sh/53k2n.png
---
Woke up, used it for radio(downloaded TuneIn for radio) + news(aka Reddit News) while eating, for one hour. Still no wifi, gps, bluetooth and automatic brightness on
http://puu.sh/53k1C.png
So it ate 20% battery on 1 hour with radio + Reddit News. Used the phone the whole time, screentime was 47m out of the 1 hour.
---
I just reinstalled everything, again, and did another test. Havent touched any app at all but YouTube. Wifi and GPS were on as default and didnt touch that. I opened YouTube and played a 2 hour movie with auto brightness and 50% media volume. This was the outcome
http://puu.sh/53jUQ.png
The red line shows when the video stopped. So it drained 20% battery on 2 hours.

What do you think of this, how is your battery life and are you satisfied with it?
I'm wondering if I should send mine in for repair, but I dont know if its my device or just pretty normal of a Note 3...

My phone is not rooted, My phone lasts 2 days with moderate usage, no charging, it last a full day with 65% by the time i sleep after a pretty heavy day of Youtube in HD Over LTE, Games, messaging and others. I don't use wifi.
Phone stays really cool too, so i can see and feel this efficiency could possibly contribute to such a fantastic battery life!

I bought this device last Thursday so it's been 9 days now. I need to probably spend another 10 days.
I have to say, as a power user, I'm not very impressed yet. Coming from an S3 (3G), I expected a significant "road warrior" bump but I'm just lasting a full day. When I heard reviewers going on 3 day weekends where they used the Note 2 and it lasted easily 2 days, I expected the same with the Note 3.
My work day is 0600 - 1630. With my S3 in moderate/heavy usage pattern I got home with maybe 15% remaining. With light/moderate usage, I'm home with 30%.
With the Note 3, my moderate/heavy pattern gives me 25% battery remaining for home. Haven't done light moderate yet. Estimate maybe 45% battery will remain.
In both cases we're talking about 3.5 hours on screen time heavy usage. 1.5 hours light usage.
Of course it should be noted that I'm comparing a 3G device to a 4G device. Also, EE 4G in London seems to have pretty week mobile signals or the Note 3 just has a meek radio. I'm really hoping that this improves after more charge cycles and/or updates. I want to be able to have a average screen on time of 4 hours and still go home with 35% remaining so I can still use the phone for the rest of the evening before bed.

Hence why when I am within a Hot Spot I switch to GSM network for full bars more or less which also conserves battery.

Terrible battery life. Compare battery stats!!

I am only getting around 5-6 hrs of screen on time with moderate usage. Android system and android os are probably the main problem that is causing this battery drain. Can you guys show me how ur battery life is and if u are having the same problems.

Also does ur battery stats show mobile data turned on even when it is off??

That's not bad, it is average for a phone with such power. The Note 3 was the same way. That is why they made and sold the Zero lemon battery and case for it. Which was three batteries combined.
Mines been up 13 hours and is down to 57% with the screen being 37% of the load becuase I keep brightness on max at a times. I also have bluetooth on all the time for my car as well as SPARK looking for a connection all the time.

Yeah 5 to 6 hours of screen on time is pretty good. I would say if you want anything more you need to get an extended battery.

Let your WiFi sleep when screen is off.

If your wifi sleeps when the screen is off, it will use 3/4G to collect data. I wonder if that is better or worse?

I believe the wifi scanning will drain the battery more. If you are truely concerned, you can download deep sleep battery saver and it will turn everything off.

I consider that Pretty good battery life coming from the n5.

I got 24 hr screen on time today.....plugged in. I'm sure I can get longer screen time too!

I used the 50% off coupon code Samsung sent me for buying the phone to order the spare battery and charger from their store... After code it was only $20! Now I'm not worried about battery life lol. Just arrived yesterday

And THIS thread is the reason I'm looking forward to my upgrade date Nov 1st. My Nexus 5 tapped out after 6 hours with only 2 hours of screen on time.

I've had 8 hrs of screen on time with moderate use on my note 3. Even the s5 that I've used gotten better screen on time than the note 4

Tried installing better battery stats, required install as system app and wasn't working.
Now it won't uninstall, reboots phone!
Can someone help?

I'm actually very happy with my battery life. I had a rooted GS3 before the Note 4 and I bought the ZeroLemon extended battery for the S3. I had decent battery life on that but I use my phone so much, with the screen on, that I wanted to stay off the charger for more than 4-5 hours at a time.
I was concerned about the battery life with the Note 4 before I got it because I've never had a Galaxy Note before. I have to say that I absolutely love the phone and the battery life I've been getting! I'm not rooted, at least not yet. I'm getting 6.5 to just over 8 hours of screen on with moderate to heavy usage. I am on WiFi almost all the time. I hardly make or receive phone calls but I do text and use WhatsApp a lot. No Bluetooth, no NFC, haptic feedback turned off for everything, brightness turned down very low. Mobile data turned off when I'm home since I'm on WiFi. I use the s-pen quite a bit. I use Tasker to change some settings when I go out, come home, etc. I play games (Restaurant Story, Stand O' Food, and some others daily), watch YouTube, Facebook, XDA app, lots of reading articles using Chrome Beta, lots of apps that I'm sure don't tax the phone too much. I use the black background for every app that has it as an option. Now if I've been playing GTA: San Andreas then the battery crashes fast. LOL But that's expected.
Anyway, I'm just trying to give an idea of what I do on my phone. I consider my usage to be pretty heavy but everyone has their own opinion of what heavy or moderate usage means.
Edit: amazingly I just hit 9 hours of screen on. I'm down to 2%. Now that I hit 9 hours I can plug my charger in. LOL Saw it getting close so I waited.

Wow that is awesome. I have never seen a device get that much screen on time without being rooted. Is it a software problem for me then that is causing a battery drain ?

Post your battery life info *stock rom only*

Hey guys, I'm using the iPhone 6 plus now and I'm seriously thinking about switching back to android. Just can't stand iOS. My only concern is the battery life since I got excellent battery life on the 6 plus. From the reviews every reviewer says it's very good battery life but I need to hear real experience from actual users here. How is the standby time? Screen on time? Please stock rom only and please post screen on time and overal battery screenshot. Thanks!!

Standby time? Lol I've been on it too much for that. Battery is excellent don't sweat the move from iphone.

My iPhone 6 plus has exceptional standby time so it gives me a feeling that the battery is endless. For example, how much juice does the note 4 lose overnight? (7-8 hours)

Bluetooth and wifi always on, pebble connected, poor coverage area. I keep it set to pick up lte when available, but I only have edge where I live. I travel a lot though and still get good life when I actually get lte. I haven't tweaked anything (yet). Be warned that my first charge gave abysmal life. It wasn't until the second or third charge that I started getting decent life, so don't worry when your first charge runs to nothing after 8 hours.

Amen. I use powersaving, and you could always use the ultra power saving in a bind.

Around 0 to 1 percent. Maybe 2 if I get a bunch of notifications. My fiance has the iPhone 6 plus, trust me my note 4 destroys her iPhone in battery. With light to moderate use I'm easily getting 2 full days ( I send roughly 500-600 texts, maybe 20 emails, at least 20 phone calls, navigate to appointments and I'm always on pandora....also I have a moto 360 connected all day). When I'm doing heavy usage I get about 24 hours or so. But my heavy usage is actually HEAVY. I can almost guarantee you don't use your phone more than me. You will be fine with battery life.

Thanks for the info!! I glad it does well with Bluetooth since I might buy a smart watch later. I intend to let Bluetooth and gps on,plus streaming a lot of spotify. Time to ditch the 6 plus.

Brightness at 50%. GPS on, Sync on, MultiWindow on.

Excellent battery life. I use my phone almost all day and night. FB, messaging, music, texting, phone calls, camera, reading, photo editing, youtube. I use it extensively on a daily basis during the week. On weekends I don't use it as much so I have more than half charge by Monday.

I turn on power saving mode at 100% when i go to bed, and when I wake up 5 hrs later I'm usually at 99% or 98%. Without power saving mode, I wake up to 96%.
I can easily get through a full day at Disney World (about 8 hrs) with light usage - mixed use of wifi and 4g, checking the disney app and checking my farmville farm, and checking feedly. I usually leave Disney with about 50% juice left. Brightness on auto, wifi on, bluetooth off, gps on.
I've tested streaming as well. On 4g, starting at 100% charge, I can stream about 4 hour long episodes on Netflix, on Plex it's usually a little longer than that before it hits 50%. At home on wifi, I can stream about double that amount before hitting 50%.
I'm pretty happy about the battery life, and the best part is I can always remove the battery if this one goes bad, or bring spares on trips. I can live with Touchwiz if it means I can have removable batteries, sd card, and the pen.

I've done multiple tests on this. I will charge it up at night 100% then leave it off charger for the night, look in the morning. I'm averaging 3-4% discharge per night which is not too bad. My Nexus 5 was a ridiculous 10-15%. Still nothing close to iPhone that just doesn't go down if you don't use it.
I leave all things on. Don't really want a phone that acts like a 2002 device.

Hey all,
Ok So My battery is at 23% with 4 hours 45 min of screen time and it's been of the charger for 1 day 20 hrs 15 min and 20 sec

The phone charge so fast and it is amazing. I dont know if I want to do that in the long run bc fast ch arging is bad on battery!
I have a nice battery charger and it says charging the battery slow will last longer per charge and longer life cycle itself too.
So what do you do?

I returned the iPhone and have used the Note for 2 days now. Battery is... Well, not as good as I expected. At least not comparable to the iPhone 6 plus. But I don't sweat on this since it does take quote some time for Android battery to kick in. I kinda wish Samsung didn't push the pixels since it's truly a battery drain. Also the GPS drains battery too. These 2 functions on the iPhone are very efficient.
And yes fast charge is wonderful. I say don't worry about the battery since it's fairly cheap.

Simple fixes.
1.) Make sure you screen brightness is on auto
2.) Put on a background that is dark, or mostly black
3.) Set your location to device only (GPS only)
4.) Turn the run time to ART
You will easily see an increase in battery life.
Below is my normal battery life. And an example of a good background to use.
Had about 5.5 hours of screen on time.

I actually switched from GPS only to power saving. I have quite a few email syncing tho. One interesting thing... Are you sure we should be on art? I heard its not fully compatible.

ART bogs down my phone so I don't use it. Also during boot up, it take forever to finish as it tries to optimize some apps every time. About 39 on mine. This makes my phone super hot and there's no way to bypass this process. I say ART is a bad idea.
