Why does my battery drain so quickly? (Details Inside)

I have always seen threads here of people getting so much better battery life then what I am getting.
I am down to 80% after 1 hour and 14 minutes after unplugging from the charger.
Here is my configuration:

That's about it. If you have any other questions please let me know.

Just a shot in the dark, but you have a lot of widgets running, and your over clocked, as well as having a live background, my guess is its draining as it should be!

My 2 cents: I just lost 30% in 2 days with my setup... try it out.
Switch to intersectRaven's 33.4 Kernel (the 925mV Version, Latest Release)
Download Task Manager (i use the regular one with the little green android)
Setup Task Manager to ignore only 2 or 3 important apps (like the clock if you use an alarm) Also, set it up to kill all tasks 5 mins after screen goes black.
That should increase your battery life quite a bit.

Well the kernel is undervolted so having it overlocked supposedly doesn't decrease battery life. As far as the widgets and live wallpaper go, I thought they don't use that much battery?.

I've been meaning to try a new Kernel. Thanks for the info, I will try intersectRaven's and see how it goes. By the way, you lost 30% in 2 days is crazy! What type of usage have you put it through?

Am I the only one who thinks it's a heavy use and the drain is perfectly normal? I can bet that during those 1.25 hours the phone rested maybe several minutes - only the drain from reading a couple of articles would cover 10%...

Nope! I can drain a quarter of my battery, at home, while using 3G, just browsing the internet, in about that time...

Well I never thought of it that way. The articles weren't that long (3-6 paragraphs) but then again I am not sure how much drain NewsRoom has when it fetches them.

Not sure about fetching, probably not much. But screen being on (and probably with white background and non-minimal brightness) for the time of reading drains a lot.

I finally rooted last night and flashed cyanogen latest ROM and now suddenly have the same poor battery life. I used stock for 3 months and this is an enormous difference than stock. I'm at 59 minutes and down to 76 % already. I have no apps installed or any widgets since I only just flashed. Stock cyanogen. So why is cyanogen So power hungry?

Pure calendar.
I totally respect the programmer and love his apps. But everytime batery has been an issue removing the widget has usually been tied to better battery life. Placebo ?..maybe..
I got terrible life with Cyn 6.05
Helix is supposedly a battery raper. That + Pure would suck Batt life like mad for me.
Both 5.05 and Froyo give me much better results.

Yeah it definitely is Cyanogen. Since I flashed Froyo, my battery life has doubled in comparison to CM 5.0.6 (I hear that 5.0.7 is even worse).

Ive been wondering the same thing and considering installing his "perks" seperately.
I do wonder if its Helix. More than a few times Ive heard people claim piss poor battery life.

I had terrible problems on CM 5.05 and 5.06. I tried what I thought was everything: setcpu, taskmanagers, every kernel known to xda. Nothing helped.
And then, one day, when I had stopped trying, I noticed I was getting good battery life again. What changed? My main suspects are replacement launchers, such as Helixlauncher etc., wifi turned on when no wifi is available -- this was big one!
And apps trying to update all the time.

Your screen was on for 44 minutes out of 74 minutes? I'm going to label that a big fat duh.

juice defender works great doubled my batterylife

I am a battery cheapstake and get pretty good battery about a day and change, with one hour on the phone and some google searching/mapping and surfing and a game or two, if you do the following:
Keep screen at minimal. You can increase it on command from the command widget if you really it, like when outdoors in bright sunlight. It takes 1 second to change and it can save you tons of battery during the course of the day.
Same goes with keep the battery to turn off after 15-30 seconds. Again, over the course of the day it adds up.
Remove live-wall papers, they are nothing but a drain. I am an photographer enthusiast so I use my own photography, a dark shot to save on battery as well. Plus it is nice to show your own stuff than someone elses.
Use no polling widgets, unless you need to. I only have 4 widgets and none pull down anything from the net at anytime. If I need twitter, it takes 2 seconds to open the app.
One of the widgets I DO have is the 2G/3G switch. When the Nexus is in my pocket, I do not need it to download/upload/sync with anything at lighting speeds. So if anything gets updated, it will be slower but I do not care. If I need the phone, I switch the puppy to 3G and fly. Savings are HUGE and guarantees my phone will have juice when I NEED it, and not use up while on standby.
I read that having task killers is a waste of time on Android. Since it is not a Windows device, ram and apps are not handled the same way. I used to kill everything on site on my old Tytn so I thought it natural. However, I read that Android is fairly good at memory managment. So for now, what I do is back out, out of all my apps --unless they have an 'exit' option. I am currently experimenting with that, after using a number of task killers from the market I think I have a fair idea of what I should and should not expect. I will let you know.
If you really want to make a difference, uncheck 'background sync' on settings under the sync option. If I need to check my email, I can again, pull it down fast. I know a few people who want to have everything push, however, unless you are that popular that you get emails\twitter & facebook notifications every 2-minutes or because of work then it is not really needed.
It is a bit of a trade-off, but you can't expect to have a running a 1Mhz chipped, huge screened, live wall-papered, widget-polling that is always connected to the internet device and expect it to to last you more than a day with an -in my opinion, fairly small- sub 1500mAh battery. If you had, say
<3000mAh, ahhh..., then that would be something.

Feels a bit cramped but i like the swipe to the media section. Either way great to have options good luck with getting it to work fully.

5.0.7 worked wonders for me batterywise.. better than stock AND slightly better than Froyo.
Is weird that some phone works better than other phones with the same ROM...funny..
I would revert back to Cyanogen if the wifi could stay constantly on. Thats the only thing stopping me.

[Q] Note Battery drain? Rate Your battery Life!O_o?

Hello,
im thinking on buying the Note =]
i wanted to ask "heavy","excessive" users how is the phone battery drain ?>
*how long your phone lasts without charge (excessive,heavy use)?
*how long your phone lasts without charge (normal use)?

Im only use any of my smartphones with excessive,heavy use.
I have only 2 full battery circles and im using stock root rom/kernel.
All my phones was with very good custom kernels and lower voltages cause i wanted to stay alive during the day (8-23:00).
Now,my battery keep up the day but more easy than my previous phones (you can see which in my sign).
So, even my battery is new with few full circles, even im not using custom kernel for uc or uv, its better than my previous smartphones.

For a 5.3" display the battery life is exceeding expectations.. Based on my usage it has more battery life than the Galaxy S2 altho movie time is still the same at 8:30hrs to 9:00

I think it's very hard to define excessive vs normal use. Also the usage patterns of different people varies greatly. mostly because some use wifi on 100% of the time, others just turn it on here and there to check emails. Same for background sync and autosync which are battery drainers . So it's really hard to compare...
I keep my Wifi constantly on, background sync on, autosync is off but I have a task in Tasker to autosync every three hours manually. I have some push emails in K9 and twitter, gtalk and tapatalk syncing.
So on a day of super heavy usage the phone will last about 16-17 hours (ofcourse that includes about 7 hours of sleep time). With normal to moderate use I can make about 24-27 hours.

Hi people! I'm noob here! (wanted to write new but couldn't resist!)
I recently bought the Note and been having a few hard times with a couple of things.
One of the specifics concern battery life. Having been showered in the awesomeness of a 2,5 ma battery i thought the battery would be invulnerable but i was wrong.
The first 4 days the battery lasted me quite fine having to charge the phone once every two days. Heavy consumption was done for brief periods of 1-1:30 hours where i would try to shape my phone in the image that i wanted.
By the end of the fourth day i had a respectable amount of apps inside but not too many to explain the fact that my battery life now has decreased to 1 day.
I kinda panicked when i noticed the difference and went ahead to install Juice defender and advanced task cleaner apps. What's weird is the fact that before i did i would charge the phone before going to bed at night and then pull the plug when it would be full. By the morning the phone had lost about 25% while inert!
Noticing that i would go to the battery use feature in settings and see that the radio(!) which i hadn't been using was eating away my battery's life along with the screen which was inactive as a consequence of the phone in locked mode and a few other apps which filled the rest of the loss.
I tried to kill apps and i use Juice defender pro in custom advanced mode effectively rendering the phone dead after locking. It still consumes the same percentage of battery although now it blames the radio less and the live wallpaper more.
Am i to assume that my battery has reached it's "puberty" and that's "normal" from now on or is there a problem i just can't diagnose due to lack of experience?
This phone is my first android device. I do not know my way around it although i am learning more and more in a rapid learning curve.
Please note anything you might think has escaped my attention.
Thank you.

Your question is a little OT but i'll try to answer real quick.
25% loss of battery sounds about right if you have your Auto Sync ON.
Disable it and you'll go down to about 10% a night. Am i right or am i totally off here ?

I'll try it and see tonight. Thanks mfractal. Having been an IPhone 3G owner i gotta say, it's still kinda disheartening to see that 10% battery loss overnight is considered "normal". Will work my way around purchasing a second backup battery for emergencies.
Thanks again.

i also come from an iphone, and yeah, you have to make some adjustments.
you can take that drain to 1-2% if you disable Background Sync.

this was my batteries first full cycle. but you should get a general idea of how it performed.

running AntoniomistrettA ( http://forum.xda-developers.com/showthread.php?t=1372619 )
this was what i would consider 'heavy' use, atleast by my standards. Edge only, Auto sync on, brightness at 75%, fairly frequent use.

Draining twice as fast after an update on apps this morning!
Hmmm, I have been using the Note for about 2 weeks now. With Juice Defender installed (with aggressive settings), I get by OK with the battery for a full day.
Well, that was until this morning when I ran an update of a few apps, and now I barely got to noon when the battery went completely drained. Same settings on Juice Defender.
Any clues on how to deal with this? I am thinking of reverting all the updates to double check.

guys, the steps to analyze battery drain are quite standard.
Download BetterBatteryStats (there's full version for free for XDA users, search the forum)
Download CPU Spy
Charge to 100%, reset statistics in CPU Spy and let the battery drain to 10-20%.
Then Analyze wakelocks in BetterBatteryStats and you will see which programs keep your phone awake.
If you want to make sure the phone is entering sleep mode and staying there, reset cpu spy stats before going to sleep and check in the morning. more than 90% of the time the phone should be in deep sleep. If not - again, betterbatterystats's wakelocks will show you what's keeping the phone awake.

sure NP.
problem is that background sync is required by quite a lot of programs to function correctly. Hell, market won't even open with it disabled.

My battery life is pretty good atm considering its still a new toy and gets a heavy workout.
The battery life will improve over time as my usage will drop but with the screen it pretty much can replace my pc for any basic web stuff outside off the heavy duty work only a high spec PC is good for.

Disabling background sync defeats the purpose of having a smart phone, no?

I do like my phone and the screen real estate, and understand that, it can be major battery hog. But I would really like it to be super efficient when the screen is off.
I was looking at my battery drain graphs, (Settings>About Phone>battery usage) and noticed that my phone is active almost all through the night, (even when the screen is off).
So i loose 25-30 overnight, on IDLE.
Is this normal?
I'm using Exchange instead of the Gmail app for my mail. Does that use more battery?
Regards

Of course gmail use more battery like every app running in background and syncing.
But your battery drain overnight is really so much.
The normal is 1% per hour without any app syncing in background and about 2% or 3% with background syncing apps.So you must check your apps.Something draining your battery.
Overall,i don't believe that note battery isn't good.i think Samsung haven't done so good work in filmwares and apps.
I have removed the most of Samsung apps and my battery is great.
Maybe a update from Samsung solved battery issue.In nexus previous days released a filmware update which change amazing the battery life.users mention that they loose 2% overnight.And before this update nexus battery sucks!
So, we must pray for something similar in our note from Samsung...
Sent from the best smartphone, Galaxy Note...

Do you have auto sync on? If so please turn it off and watch the drain overnight drop to about 10%
If not then we got a problem

I got my Note two weeks ago and am since struggling with my battery usage as well.
It's hard to reproduce, but Android OS is the reason for excessive battery usage when the phone is idle.
Today I found this quite interesting. Please have a look at this screenshot:
Since a few days ago I'm using Llama to control some settings on my phone, but the drainage was present before I installed Llama.
When you look at the first gap in WiFi usage you can see the phone disconnecting from my WiFi router at home (TP-Link TL-WR1043ND) when Llama disabled my WiFi.
About 20 minutes later, when I arrived at the office, Llama reactivates WiFi and my phone connects to our WiFi access point at the office (TP-Link TL-WA801ND).
At this point Android OS usage goes up considerably and it won't stop, even if I disable the phone's WiFi.
Actually at the second, larger gap in WiFi usage I disabled the WiFi connection manually which caused my phone to stay awake until I activate WiFi again.
Edit: Using Titanium Backup I have frozen Wifi-Sharing and the Wifi Manager.
Apart from that, Wifi usage was never an issue on my old Milestone, where I had Wifi enabled permanently and the battery lasted for 4-5 days.
I'd be glad to provide more information if that could help figure out the cause of AOS's battery usage.
My phone is currently running:
PDA: N7000XXKK9
PHONE: N7000XXKK5
CSC: N7000OXAKK9
I installed FM-Kernel 1.4, hoping it would fix this issue. It did for a day or so...
Apart from the kernel it's the newest 2.3.6 stock ROM I received via FOTA though.

I easily get a good day out of mine with quite a bit of use. If use mine lightly I can get 2 days out of mine. If you are in need of urgent 3G switch 3G off to GSM to conserve battery life.

Sorry, I forgot to include it in my post.
Since I got the phone I have it set to 2G only, because I used up my monthly quota and am getting throttled to GPRS speeds anyway. So the 3G connection isn't the issue either.
Apart from that this happens in flight mode as well.

GALAXY Note: Battery life is so less. ?? (Please Help)

Hi everyone. My battery life is really sucks. I bought my item two days ago. It is new. And I upgrade my version and baseband , kernel and build version like below :
N70000XXLB2
2.6.35.7-N7000XXLC1-CL1003701 [email protected]#2
GINGERBREAD.XXLC1
I think that this version xxlc1 is last version but I wonder how is my kernel version ?
Battery life is very bad.
Moreover Charging lasts so long. 3 -4 hours sometimes.
PLEASE Help me! please

depends in the usage, rom, kernel, settings etc you are using.

when i see some kind of usage experiences, I am so jealous. How they use this much ? HOW. I only use wifi and radio.

Hi,
What is your battery life on the Note? Does it last a day even two?. If it does, then that is pretty much normal. You whine on a phone that you just use for only 2 days? Stop whining and complaining. You havent have had utilize the full charge and recharge cycles of your battery and now your whining already.. Man, give your Note a week or two and your battery life will be okay.
Hmm.. Is this the first time you use an android device? What phone where you using.before? If you we're using a non android device e.g. Symbian or etc. Then my reaction to your complains (of your Note) is justifiable. Symbian for the fact has always been known to be very good or decent in terms of battery life.
Now android OS, is known throughout (irregardless what smartphone/tablet you have) to have the AOS bug. It is a bug where there's some sort of a battery leak and hencefort most android users tend to root their phones so that they can stop background stock applications from running in the background. The births of custom ROMS and Kernels have given some tremendous wonders also especially on phone's UI and more so on battery management.
Again. Stop complaining and go down root your phone and install battery saving apps or custom ROMs. It's all over the thread anyway.
The sooner you customise your phone to your heart's content, the better you can appreciate it's full potentials.
Cheers!!!

My battery life is 5 - 6 hours. I am accept 12 hours. I wish it last 12 hours. Before I used Iphone4, it is not so long for battery life , however it is acceptable. I did not understand how notes's battery life so short.
Moreover I can not use custom rom. because they r not good as well as stock rom. ALl of them have some problems. But I can change my kernel.

to get battery life you either
a) dont use your phone or
b) get information to use your phone more wisely
So..
a) download a battery monitor.. there are a bunch recommended..
b) read the other 200 threads on battery life and dont start another one. Each and every question has been asked and answered ad nauseum
while you are figuring out root, and task killers, here are a few easy tips to help..particularly when you are putting the phone down for a while
apps>task manager>active apps> CLOSE ALL
apps>task manager> RAM> CLEAR MEMORY
settings>applications>running services> review and shut down apps/games that may be running in background (and that are not critical)
Again.... RESEARCH the forum.. the answers are already here. and you should read and post in existing threads

You could also have a defective battery.
On my iPhone 4, my first of 4 that were faulty, battery life depleted in less than 12 hours of STANDBY only on wifi, nothing syncing. Only being on. Battery life was so bad.
It's not uncommon to get a dud battery sometimes.
Try doing a complete restore, stock EVERYTHING, don't push anything (except email, cal, and contacts, you know, the basics) and see if you're having the same results. If on a fresh, stock, install you're having the same issues, then you've got a defective unit and/or battery.

My battery life is 5 - 6 hours. I am accept 12 hours. I wish it last 12 hours. Before I used Iphone4, it is not so long for battery life , however it is acceptable. I did not understand how notes's battery life so short.
Moreover I can not use custom rom. because they r not good as well as stock rom. ALl of them have some problems. But I can change my kernel.

There are quite decent custom roms for the Note. I have tried many gingerbread versions (Chracks, rocketrom, cassies etc) currently on chrack's v18 small (LC1) with speedmod latest kernel.
I have not faced performance issues on this. But each user is different so u r the boss.
Best give the custom kernels a try for now. If u find the battery life better then ur problem is solved. The advantage of custom rom is that so much useless bloatware in the stock is removed for better space mgt & performance.
have provided some tips in the following link, feel free to go thru.

dude, you are ridiculing some of the well known devs who have made custom ROMS for all to appreciate and use. IF there was and is a problem on a particular custom ROM, it is or might be cause indirectly on the user itself, on what apps he/she insatalled on his phone. Surely you cannot generalize all custom ROMS have problems do you? if all have problems, the devs have some new revisions to fix those bugs and in no time at all your Note would be in tip-top shape again.
If as what you say, Custom Roms have problems.... then why the heck most people I know have used them and have big wide grin on their face to show off what they have and even posting a copy of their latest ROM pictures here... not to mentioned in YouTube as well.

ok. Which rom is the best stable than ? Which I should use ?

go read the threads on battery performance.. loading a new ROM will not fix problems if you do not know what you are doing.

first quote :laugh:
Hi there.
I had the same issues but only after the update done on ICS.
I have over 140 different application and nearly all of them have been purchased.
What happens is that, when you are not using your phone it should go to "deep sleep". This allows your phone not to run any application and merely use any battery. Your problem probably come from somewhere in your setting an automatic update. That drains a lot....
I downloaded different application hoping that it would work out such as Juice Defender, watch dog and many others. After lots of research, I found out that it is not good for your phone to have an auto killer app or even an application that modifies the functions of other applications.
So I downloaded battery spy and cpu spy on "google play" and followed the instructions.
I needed a deeper analytic application "Kernel" and this was THE application that allowed my phone to go from 6-8 hour to 28 hours.
"Better battery stats", it's not free but was really worth the spending.
Google play chronological download
1) watch dog
2) battery spy
3) cpu spy
4) better battery stats
Good luck

I keep switching my cellphone off while not using, and same goes for wifi. Using it as a secondary phone as well. It lasts only 4-6 hours.. :S I keep closing background apps, and kill app once im done with it..

Also be aware that in areas with bad network strenght, the GNote really suffers.
I normally have no complains (0,6-1,5% battery usage per hour) but where I am now, the GNote really works hard to keep the connection and my consumption easily goes to 4-6% in deep sleep and 15-20% when using it...

If you like stock samsung looks try CleaNote 3.10 , very good n battery life , I get around one day backup with heavy usage and 2 days plus with moderate usage .
If like pure google , then try cm9 , very stable and quite good on battery back up .
And if you dont use 3g or 3.5 g or any such networks then select GSM only or use 2g networks only ( Settings -> under wireless and connectivity , More -> Mobile Networks )
Also keep your display brightness to minimum , control the brightness manually instead of auto brightness .
Turn off auto sync ( big advantage over battery ) .
Scan for running apps and cached apps and force stop the ones which you dont use .
Use titanium back up and freeze some of the bloatwares ( stock samsung apps ) or uninstall them , like readers hub , mydiary , they are **** .
And dont use task killers , they drain your battery . they may clear rom but some apps restart automatically and that needs more juice than running those apps . Hope all these suggestions help . From my experience with this phone

I didnt know that, My signal is usually 10-40%. I have bad signal strenght at home.
my battery decreases 1% in around 5 minutes of use or something. Today it lasted me 10% on standby for around 8-10hours.

You need to purchase and install "better battery stats" and also install cpu spy (I'm assuming you're rooted) and use them to monitor your phone and battery in order to solve your issue. Google both and you'll find several good threads on xda about using and interpreting these apps, but if you get stuck post some screen shots from both and someone here can almost certainly help. There are a number of potential sources of such problems, generally rogue apps, and also a bug or two, but it is impossible to offer help without the details these apps would provide.

Thanks for that, i will install it. By the way i got the "battery widget" installed, which has gained popularity on the market.
Also im only using 9% of brightness of my phone.

I'm using a rooted stock 4.0.3 and I'm finding battery life its pretty good - better than unrooted GB was in fact. Simply freezing bloatware via titanium and limiting sync on some (not all) apps and services makes a gigantic difference. Design your phone around your own needs and you'll end up with an amazing device that you'll fall in love with all over again.

The Sony Xperia SP, A heartbreaker Smartphone

Hi, I bought this phone a month ago, I bought that actually looked like a very good phone, analyze their characteristics, not only its design, and discard the possibility of buying the Samsung S3 Mini, I think it was a mistake :crying:
This Xperia SP is really a headache, the first thing I knew I was bad at was his poor WiFi, later learned of the problem of the screen, which to place the phone on a flat surface the touch becomes useless (I is how to fix it), and now the battery, then I have seen pictures that the battery will last up to 2 days, I was never happened in 14 hours, or when you use it the first time, now active or inactive so I Sstamina gives up to 7 hours, which sucks .
Originally came with compiling 12.0.A.1.257 and decided to upgrade to the 12.0.A.2.245 to see if suddenly improved, big mistake, the 2245 presents many problems in the stability of the OS, the screen flashes when using certain applications , Stamina mode is "Arrangement" a bit, as the cell I last up to 12 hours, but it's all over.
In conclusion I am determined to get rid of this phone, and all who ask for me, I gonna Scream, NEVER BUY THAT MTF CELL, which by the way is a bit expensive for the problems to come.
Sorry, my english is not very good :silly:

To be honest with you- the WiFi does suck on the sp, even though there are many fixes none of which will work 100% . Ive come across alot of problems with my sp also, keyboard wont pop up, walkman crashes when using certain apps. But on the plus note there is deffo an upside to the sp compared to most other mid range smart phones out there.
I have smashed my screen on my sp and have no warrenty- so im switching over to a s3 mini, simply because a new white digitiser for my phone would cost me £135.
Play around with your phone first see if you can make any good of it before you sell up

Whats your screen on time? Also ho do you use your phone? Heavy gaming or light texting only?
Things will always matter when you want to compare battery life. So give us more details. Install Wakelock detector or BetterBatteryStats to know what is eating up the battery on your phone and then work on eliminating the factor. Cheers man!

I do not play much, texting, only play when I'm charging the phone, cut the rope and Diamon Dash.
In the images shows that the battery is low 2% in 29 minutes
Ok, i do it, the result from battery stats plus.
After it, I think do a factory reset, to see how it behaves.

I think you should. Your Android OS is using too much battery. Hit on it and check which process is using the maximum battery.

Once you've charged your battery to 100%, go to Apps, All, and look for eco mode controller. Click on force stop and after 5 seconds or so, clear data. Then reboot your phone and use it normally. Check out my best battery life so far (attached images)

Battery life not quite as good as I hoped
The battery life on my xperia SP is not bad but it is no better than my previous xperia neo which had only a 1500mah battery versus 2370mah.
Many reviewers have commented that they can get through 2 days.
I can only make 1 and a bit. The key problem appears to be the screen. I can use the screen for about 4 hours/day before I'm out of juice, some reviewers claim 7 hours. Thats a big difference. Using it outside of the time is always going to be worse but screen on time is a bit disappointing for me. Stamina with screen off seems reasonable but again not outstanding. I lost 13% between the morning and lunchtime without doing anything but 15 minute syncing, I use a battery saver, not stamina mode as I don't want to shut down all my apps and have no data at all when screen is off.
Phone is only 2 weeks old, can I recalibrate the battery? Seems to stay on 1% for a while too. On the contrary, my wifi reception is really good. Better than any other phone I've had.

Yes you can, but you need to root your phone. Some people say its useless to do It, but you can try.

Got a bug less device
Sent from my C5303 using xda app-developers app

Battery life on standby is perfectly good for me – a few people have said that the estimate Stamina mode gives is based on recent usage. So if you haven’t had the device very long of have just had a big session on your phone the estimate might not be very accurate.
Most mornings the battery is 0, 1 or 2% down on the reading before I went to sleep…deep sleep is being enforced.
However, I don’t think the battery consumption with screen on is anything special – not bad, not exceptional.
It’s a really good phone IMO. I admit WiFi seems badly implemented and you shouldn’t need the tweak which seems to fix it for most rooted users (all manufacturers seem to still release phones with Wifi problems). But with this tweak in place I get better wifi than my old xperia (it had a custom kernel that gave it awesome range) and better than my wife’s Samsung S2. There’s a part of my house where we couldn’t get any signal for my old phone or laptops – amazingly the SP can connect!

My C5303 drained battery like hell, with less than 5 minutes on screen time, it drained 2% per hour.
bluetooth, nfc, wifi, data disabled( sim card does not have data), mobile network wcdma or gsm only
stock .245 generic RU rom rooted with bbs installed,
top of the list wakelock : superstamina xssm (nobody in this forum can fix it)
battery drains : cell standby and phone idle
already factory reset over 5 times, nothing works
is it a rom problem? app problem? simcard problem or battery calibrating problem?
really need some advice here, had been stuck with this ****ty battery life for 2 motnhs

I think that is a problem in the OS of the SP, as put or dimly lit screen this will still consume battery as much lighting.
In my case the problem was corrected a bit, I deleted widgets, some app that did not use, the antivirus was always eating, I set to use 3G only when I need it, otherwise I'm on 2g most of the time, not game unless it is connected to the charger, WiFi and GPS only when I need them, listen to music and write a little and this we see is the result, compared to what it was prior is something a little encouragement ...(Attached)
But, why have a midrange phone if you will not be able to use to stop because two hours is dead? the Sony need to fix that big waste of battery.
I will continue to see what happens, disconcerted me the Android OS consumes much battery 45% to 52% long
Please, helpme whit this, why there are applications that I am using, or have not opened, but are consuming battery?, How do I prevent them from running without my wants? any program to control the apps that connect to the internet?

Check which processes in Android OS is running the most. Install Wakelock Detector and that should help you get there
Also, hibernate apps that are running in background. Use Greenify for the same.

In the images posted I can see Mcafee and Lookout. I would suggest removing Mcafee as I have found it to be a resource hog, my opinion though. Either way u need to get rid of one of them.
In another image I noticed wifi is always on. Go to Settings -> Wifi -> menu, advanced -> Keep wifi on only when connected to charger one. That will reduce wifi wake usage.
get Juicedefenderfrom HERE OR
Snapdragon BatteryGuru from Here
If using Juice defender, set to balanced/aggressive.
If using Viber, go into viber -> more options -> settings -> wifi sleep policy -> change to use device settings not always on.
Zero the battery and do a full charge. Post updated screens when battery is under 30% ( Please include the MISC Usage screen from BBS). I expect it will be 2 days before we see those screens.
If you can even post a screen of the Misc usage from BBS just now and we`ll compare it with the next one soon.
I use JD (gives me a 1.5x boost to battery) with Stamina Mode on (no low battery or wifi). I charge my phone on an average once in 2 days, medium.

I don't have any of those problems, the battery lasts very long, don't have any flat-surface problems, wifi catches at full signal on both my houses, never had "screen flashes", only some crashes in the youtube app.

Poor battery performance, what to do?

Hey guys, I'm wondering what can I do to improve my Note 8 battery life. Seems to me that is draining and I do not get the chance to use it too much. Maybe you have an idea how to optimize and track the apps are overusing the battery, so far I was not able to detect which app/component drains my battery. Even Samsung seems that doesn't know since there is no message regarding background processes with heavy usage.
Basically I finished fully charging at 9:15 AM and now 16:15PM time I started to write the post and make the screenshots, it has 16%. What I did all this time with the phone, was:
- a bit of browsing,
- make one NFC payment,
- have the S3 gear connected on bluetooth.
- few twitter messages and viber really small usage. (less than 40 messages overall)
So here are my settings
- WIFI is off and I'm using 3G connection (I stopped LTE thinking that requires more battery.. , correct me if I'm wrong please),
- screen not even on 50% and auto brightness off (using HD+ and a dark theme, everything is so dark!)
- AOD
- no led, no gestures (most of them I turn off for testing purpose)
- Medium battery saver on.
- No phone calls
- few notifications (not more than 20, also the notification is optimized to apps I'm concerned)
Any suggestion how to make it to end of working day .. at least?
I was waiting so long for a new note and now I'm a bit disappointed and I hope that is something I do wrong..
Funny is I just realized that by mistake I put the phone on airplane mode while making the screenshots, still percentage was flying away even like this. I lost 2% making screenshots in a matter of couple of minutes.
Please find the screenshots attached in the link down bellow, were to big to add them to the post.

Thanks!

you might have some apps draining battery. I'm used to a rooted phone, so I'd always check with wakelock detector, but I'm not sure what you can do without installing an app as a system app.
Try factory resetting your phone and using it without installing anything for a day and see what the battery life is like. If it's significantly better, install your apps 1 by 1 until you find out which one is causing unnecessary cpu cycles or wakelocks.

But I wonder, I shouldn't see the heavy usage on the battery info page? Like which app does most of the usage and time spend in the background or CPU?

I had excessive battery drain, about 10-11% an hour with every off . A full factory reset cured the problem.

What's your screen on time usage? 5-6 is probably the normal amount you would get with most phones (This is the most important thing if nothings draining the battery). And yes, it seems you might need a factory reset.

You won't always see this as it could be a byproduct causing a kernel wakelock.
Either way, something is acting incorrectly. The only way to really figure it out is to start over and try things slowly till you find out what it is.
For instance, on my nvidia shield tablet k-1, I was getting horrendous battery life on every single rom, stock or AOSP/Lineage. I found that I was getting 30% wakelock killing ~20% battery life per day when it should be sub 5%. I found that wifi was causing these kernel wakelocks and setting wifi to be disabled with the screen off unless charging fixed the issue entirely.
Now, that anecdote likely has nothing to do with what you're experiencing, but note that you can usually find out what's wrong from trial and error.

I've had my note 8 for 6 days now, and battery life is excellent, i mean i have wi-fi and 4g lte on all the time, bluetooth on all the time, sync with 3 emails, Facebook, weather widget, weather screen refresh every 30mins, location high accuracy, edge lighting, aod schedule 7pm-7am, was 100% at 6am, played games on it lots, used the phone 2x, 1 hour call and a 30 mins call, text messages, it's 130pm and I'm at 55%, try a factory reset then log in to your gmail then just try to update the phone if there is any. Then reboot then start installing your apps. If it doesn't work call carrier customer service and complain about the battery not holding up like some people you know who has note 8. They might replace it with a new one.

Phone died 15-20 minutes after I did the screenshots, so a bit more than 2 hours...
So.. yeah.. I will try a factory reset and start install all the apps bit by bit and see which one causes the troubles.. hopefully is nothing more than that.

Did you restore a backup or did you load your apps fresh from the play store?
I've had horrible luck with issues like battery life restoring from backups. I always install apps fresh.

can you translate "not great" in hours? :laugh: Because I will say that mine is second after horrible.. with update done.
I will start the reset in a short while and I will test it tomorrow with minimum apps installed.. those which I really must have in a working day..

Maximum 5 hrs on wifi normally about 3-4 battery is not great on note yet....some optimalization would be nice

I use Ampere to monitor the instan drain of current. In a quiet situation (screen on, internet or tapatalk browsing, gear connected, wifi and data turned on) you should have something 200 mA drain.

Maybe some of the settings changes you're making are somehow rendering your phone less efficient.
I have the USA unlocked version and use it as it came without changing to a dark theme or turning anything off and the battery life is much better than yours.

I restored from a helium backup. My battery life wasn't good for about a week but it did last all day down to 20-30% at the end of the day. After a week it has improved maybe due to apps updating. Now I'm at 70-80% at the end of the day with moderate use. I have disabled several apps I didn't need as well.

Seems like it's hit or miss with the battery life. I see a lot of people happy and some are having problems. Hopefully Samsung might push a update to help.

Get cpu spy and verify that your devoce is going into deep sleep when off(mine wasnt at first until i froze/removed some rouge apps). Install accubattery and do a benchmark and see how your battery does. At least do 6 discharge cycles first to see an average. Also, in device maintenance, you can make all apps doze when not being used now.. this is a new feature. Add all of your apps and they get put to sleep immediately. I get 8 hours SOT this way

Hey guys, I'm wondering what can I do to improve my Note 8 battery life. Seems to me that is draining and I do not get the chance to use it too much. Maybe you have an idea how to optimize and track the apps are overusing the battery, so far I was not able to detect which app/component drains my battery. Even Samsung seems that doesn't know since there is no message regarding background processes with heavy usage.
Basically I finished fully charging at 9:15 AM and now 16:15PM time I started to write the post and make the screenshots, it has 16%. What I did all this time with the phone, was:
- a bit of browsing,
- make one NFC payment,
- have the S3 gear connected on bluetooth.
- few twitter messages and viber really small usage. (less than 40 messages overall)
So here are my settings
- WIFI is off and I'm using 3G connection (I stopped LTE thinking that requires more battery.. , correct me if I'm wrong please),
- screen not even on 50% and auto brightness off (using HD+ and a dark theme, everything is so dark!)
- AOD
- no led, no gestures (most of them I turn off for testing purpose)
- Medium battery saver on.
- No phone calls
- few notifications (not more than 20, also the notification is optimized to apps I'm concerned)
Any suggestion how to make it to end of working day .. at least?
I was waiting so long for a new note and now I'm a bit disappointed and I hope that is something I do wrong..
Funny is I just realized that by mistake I put the phone on airplane mode while making the screenshots, still percentage was flying away even like this. I lost 2% making screenshots in a matter of couple of minutes.
Please find the screenshots attached in the link down bellow, were to big to add them to the post.

You dont have to use med battery saver either, just read my reply on this thread and you will be good. You may have to experiment a little to get your device to go into deep sleep when screen off. Mine didnt at first. Its on my other comment

I got back from work and my phone was at 75% that's between 9:30am and 6:30 pm. So my battery life is pretty good. I lose about 5% overnight.
