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.

Screens are always the main power drain on these type of devices...even your Note II.

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.

Hi all! I just get my galaxy tab 7.7 wifi only and I am very disapoited with the battery. It lost 1% each 4 minutes with just normal surfing ( screen brighness 30%) . By ipad 2 I lost 1% each 10 minutes and the screen is biger, brighter.!!! Any suggestion?
Ps: im stanby is ok. 2% for 10 hours.

Perhaps some background process? Try factory reset
Sent from my GT-P6800 using Tapatalk
just found this out a couple of minutes ago if you are using a search engine use bgoog.com aka black google it uses a black background so you can minimize use of the amoled screen and reduce battery consumption hope that helps you
black baground webpages tend to use less power than a white background
as for me battery life is better overall from my old galaxy tab p1000
Yep, I have a lot of black background applications as well and battery life is superb compared to my 6-month-old p1000, just be sure to properly cycle your battery from time to time to minimize battery degrade
My experience is that I get about 8.5 to 9 hours of screen time on a single charge with wifi turned on all the time. That's about one percent loss every five minutes.
I had heard that the iPad is rated as a ten hour battery but it seems that you have been very lucky and got a unit giving you nearly 17 hours of screen time. That's incredible and anything is going to seem like a disappointment after that.
If your unit is new you may find the battery life improves over time a little bit but I wouldn't expect much more than nine hours with wifi on all the time. The adverts claim ten hours and one review site managed twelve but I don't know if that is just looping a movie or if wifi was on at the same time.
Anyway, 8 hours is enough for me

i think you may have an app thats running in the backfround that doesnt exit even when not in use had the same problem before with my old p1000 i thought i had a lemon unit but the culprit was the a certain app forgot the name it was about a year ago you may want to use the samsung task manager and see if any app is running in the background or use a task manager on the market
and just to add, do turn off the background data on the settings, it's another power hog
I find it hard to believe that the iPad 2 can go for 17 hours of usage. Engadget's battery test says that their 7.7 lasted about 12 hours, 1.5 hours more than their iPad 2 (looping video, wifi on, screen at 50%, I seem to recall).
Also see settings> about device> battery use to see what's eating the charge. Normally, the lion's share goes to the screen. But games can use significant amount of charge too.
I've been able to about 10 hours of continuous usage (light browsing, email, xda, kindle, pdf reading on either repligo or mantano).

For video playback the Tab7.7 will have a longer battery life since it is using GPU decoding as compared to the Ipad2's SW only. But when it comes to surfing and everything else, generally for anything else apple devices can outlast samsung devices or andriod.
According to battery widget pro estimates, if I stick to reading on the kindle app, as I have been doing for the last couple of hours, I will be able to last another 18+ hours. Wifi is on, screen about 15%, background auto sync on. (Since it's a longish Neal Stephenson that I'm reading, I'm going to need that much time.)
Incidentally, I found battery widget pro very useful. Have it on each of my Android devices.

Aaawww, I feel so bummed to post this, cause I am otherwise absolutely in love with my galaxy tab 7.7, but I feel a bit iffy about the battery life aswell. I switched to galaxy tab from Asus Transformer TF101 and I actually feel like the battery on my previous tablet lasted waaaaaay more, even with the wifi switched on permanently. On my Galaxy Tab 7.7 3g I can easily lose 20% of battery power during a half an hour of browsing the internet on low brightness, with wifi, gps, bluetooth and background sync switched off...that is hardly the "phenomenal battery performance" mentioned in all those reviews. I use ADW launcher, not so many widgets, I dont even play music, games or video and still the battery will not last through the day at all...I mean..I only would use it for reading an ebook, browsing the web and facebooking 1 hour on a bus in a morning and another hour in the evening....but no chance...the battery wont last that long. It would exhaust the first 40% on my way to work, and come down to 30% during the day (when used very rarely). I can easily last the whole afternoon with switching the battery saver ON every time I am not using the tablet, but to resort to that, and to switch everything off and lowering the brighteness to miminum just to be able to browse internet for an hour and lose almost 50% of battery power by doing so, feels really desperate. I still dont want to believe I am the unlucky one to get a bad unit with a dogdy battery...what should I do to make sure tis not the case? Is there a test I can run to see for sure if I have the battery which drains the same way as the others or not??? Thanks in advance for any suggestions.
i personally have no battery problem with surfing internet . because i have use customized css in opera mobile, every page become black with white text.

Ok thanks, but that does not really help..I just wanted to know if there is a way of knowing for sure (e.g. by running a certain test or something) that my battery is officialy flawed compared to the others in these units. All the reviews for this tablet mentioned an exceptional battery life and yet I am loosing almost 10% every 10 minutes of browsing (not playing video or music, so not a heavy use really) on the minimum brightness, with gps, wifi, bluetooth, background sync, vibrations, animations switched off...does not seem ok to me.

Install a battery monitoring app (e.g., Battery Monitor Widget Pro) so that you can track/log usage.

I dont have any battery life complaints yet as TBH, i dont really know what to expect from a 7.7 Inch screen with 5100mAH of battery, suffice to say that it out lasts an Ipad2 on anything but web browsing is already good enough for me.
My battery is very good, light years aheadof the Blackberry Suckbook that it replaced. I generally get a full day of heavy use with Wifi and 3g browsing, and two days of "normal" use.

if your tab is rooted and you know the system files you may want to install nobloat and remove system apps that you don't use tried it and lowered my actual ram use to 400 to 500+ and keeps my tab snappy be warned make backup before using just to be sure
and another thing always try to clear memory using task manager when your gonna let it standy i found it to use less battery than when many apps is running in the background when on standby hope that helps
Recently bought a Nexus 4 and I knew the battery life wasn't great, but I didn't think it was this bad.
I'm running the latest version of paranoid android and is getting about 2 hours of on screen time (With 3g on, sync off, auto-brightness) normal? Or would it be worth contacting Google or buying a new battery or something.
The thing which confuses me is that some people report having good battery life while some report having bad battery life, is there a fundamental difference in their hardware? Or are they just different usage level users?

1. battery life mostly depends on your own setup and usage. we all set up our phones differenyly and use it differently.
2. try a different rom and/or kernel.
i get anywhere from 3.5-5.5 hours screen on time, depending how im using my device.

maybe its your setup? the more apps syncing in the background, the less battery. the brighter your screen, the less battery, live wallpapers equal less battery, low quality of your phone/data connection equals less battery, more rom "features" that are active equal less battery life, the worse your phone deep sleeps equal less battery, etc..

You can not increase sot and not use the device. Get it? Any time the screen is on, the device is in use and the screen just being on is one of the biggest battery users. Try setting your screen to where it won't turn off in the settings menu and then just set it down somewhere. You will find out how quickly the battery drains vs with the screen off. I get 4-5 hrs sot on cellular and 5-6 on wifi. I have background data, syncing, wifi, and gps on all the time. The things I do keep off are Google Now and Google Currents. I also have screen brightness set to roughly 30-35%. I also typically have a good cell signal, in a major metro area. When in a bad location, my sot does drop to around 3hrs.

I thought you said this, " These guys that say they do 5 -7 hours of sot are not using their device.." When I get 5-7 hours of screen time, it is because I used my device for 5-7 hours and this is typically in a 8-12 total battery period. If I don't use my device much, I can also go 20 hrs.

the harder that you use your device, the more screen on time that you will see. if you use up your battery within 7-10 hours, chances are that you will see more screen on time than someone who uses up their battery in 20+ hours. heres one of my random days usages, i dont disable crap just to disable it. instead, ive learned to take care of my apps so they dont misbehave, and have my system highly optimized. this is my average battery life. i have gotten 5.5+ hours many times, but will post this one because its my average.

I was only messing with you..
That was my pont . I have noticed a trend as of late where the majority of people seem to be in some kind of pissing match over SOT.. And depending on what your doing will affect your personal experience..

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 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!

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 ?
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.

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.
I couldn't find a thread about battery and SOT, so here it is.
Battery life is one of the most important things in today's gadgets and even if it's often up to what kind of apps and usage pattern you have there is still good to find a baseline to benchmark your own battery life against.
Please show us your battery life, SOT and any findings you have about what to do, and not, to maximize it.
If possible , please use gsam battery monitor and post screenshot. Gsam is a great tool and will also show you parts of what's going on energywise. Root is normally needed for more granular reports.
Thanks!

It's still a very early firmware and hopefully it's possible to find what's draining.
Looking forward to it, but sad news if it's the same for everyone.
Thank you!
First cycles with all initial syncs were getting me about 6:30 hours. After a few cycles, intensive usage (very little gaming, but lots of browsing, twitter, FB, sports timer, some camera etc) I am getting around 8:45. I noticed that changing brightness from default auto (too dark for me) to manual +2 (very bright) doesn't impact battery life much. I think the main drain comes from the 810 and theming.

Theming is known to be able to drain.
Is there a "stock version" that don't drain and is it possible to measure?
When it comes to the SOC, I imagine that's mostly up to Qualcomm and HTC to fix.
Actually more around 8:00 screen on with 45' screen off. Note that I disabled FB and Twitter feed sync, and configured location services only on one Google account and did not use theming on these cycles.

About 8 hours of SOT with more than 50% brightness sounds really good, even if you turn location and stuff off.
Can you upload som statistic about what is taking battery and SOT?
Thanks
8 hours is quite consistent with the reviews, e.g. Engadget:
In the standard Engadget rundown test (with a video set to loop endlessly while the screen's set to 50 percent brightness), the M9 stuck around for eight hours and 19 minutes -- a decent increase over the original One M7, but far short of the 11-plus hours we squeezed out of the M8 last year and the 10-plus hours the G Flex2 put up. That seems abnormally low, especially considering that the M9 did just fine when it came to average daily use: It regularly hung around for 13 to 14 hours of continuous work use (including a few spells as a mobile hotspot during press events) without batting an eye.

Also in my experience 8 hours with the screen off will drain 10%. This is without the phone doing much and WiFi only as I don't have a SIM in there yet.
Coming from a first gen Moto G I don't feel too concerned.

True, but most of those test is normally about looping a video, web-script, on 50% brightness.
I you just got the phone and using it in a mixed way 8 hours is pretty good. I never had 8 hours on the M8, even when reading books with flight-mode on (weekend in another country, don't want to get ruined
But... I also have close to 200 apps running god knows what in the background.

No one said they had 50% battery remaining after 8 hours of SOT. They were talking about the screen brightness being set at 50%
I think you've misread that. It's 8hrs SOT with brightness at 50%. Not remaining battery at 50%.
Here is mine so far tonight after 2 full drain and recharge cycles.
It seems the system itself is a big impact on the battery. Need a lot more work on the firmware.

I think this is the only encouraging thing anyone can say right now.
We know that the M8 is capable of great battery life. The M9 has a bigger battery than the M8 so hopefully the firmware can improve.
As apposed to the S6 where the battery size leaves the battery life nowhere to go but down.
I've been testing a Verizon version with all the test software on it so it's hard to gauge battery life. My main complaint about the phone is its slow charge rate. Takes hours to charge

I used an Apple iPad charger which gives out 12w/2.1a. It still took nearly 5hrs to charge my dead phone to full power.
My iPhone 6 plus with the same charger takes about 2.5-3hrs to charge a dead phone.
Charging m9 with out of the box charger from 12% takes me about 2 hours and 15 minutes. I'm in France . Don't know whether this is the 'quick' charger or not.
Also, power history graph crashes if I try to launch it while charging
