Possible solution to Battery issue after lollipop update - AT&T Samsung Galaxy Note 4

I love this device, but the battery drain is much worse after the update IMHO. I have reset the phone quite a few times because of it.
Following my last reset to faftory, I accidentally did NOT set brightness to auto and have had it around 50%. Low and behold, my battery life has shot up from 10 hours to 18 hours. I could be wrong and will report back in a mother few days as to whether this has done it.
Of course , I am still suffering from the GPS issue, but the battery life was going to make me switch to a g4. Maybe now i wont.

All the Samsung phones I've had (the note 4 is 4th) have all had horible battery drain if I used auto-brightness. On the Note 4, I get almost 8 hours of screen-on time on a charge that lasts almost a day and a half.
I thought it was common knowledge to turn off auto-brightness to save battery.

It is annoying. I will try as you suggested and will be tracking for a few days

I use auto brightness with no problems to my battery life since a factory reset after LP.. you can also disable enhanced LTE to get more life.
but yes even though I always keep it on, auto brightness doesn't have the greatest detection
all personal experience

I've always used auto brightness and on KitKat I used to always get around 6 hours of screen on time. With lollipop its between 3-4. I even tried a factory reset and it still didn't fix the issue.

Auto brightness is going to affect any phone on any os. It's just another sensor that consumes battery. If you think about it it's always on and always monitoring lighting conditions and making calculations. So disabling it will help with battery life regardless of the device. Good rule of thumb for decent battery life is disable auto brightness, location, Bluetooth, nfc and Wi-Fi when not in use.

Why turn WiFi off? WiFi consumes way less battery than 4G does.

When not in use

My screen is only on for an average of 1.5-2hrs a day. Most of my battery drain occurs during sleep. Phone does deep sleep though, but wakes up every now and then.
I've disable everything I can (including enhanced lte), and even set up a Tasker profile that keeps Sync off at all times, but enables it for 2 mins 4x a day (24hrs).
So I'm going to ask these questions even though I'm pretty sure I already know the answers.
Will turning off auto brightness affect standby battery.
And will it make any dramatic difference during the 2 or so hours that the screen is actually on?

Rather lose a little battery than eat up background mobile data instead of wifi though. Just my opinion.

It might be easier to help if you could share the battery stats screenshot from the settings-general option ☺.. We have no idea what you've installed or running..

I actually wasn't asking "what's killing my battery?"
I was basically just trying to ask if auto brightness will affect standby time or not. I was thinking the answer would be that with Auto on, it wouldn't affect standby battery at all since during standby, the screen isn't on, so the phone wouldn't be using battery to try and auto adjust itself.
But today I'm running my phone with Auto brightness off and so far I'm pleasantly surprised by the results. Though, today is my day off from work, so my phone is also getting atypical usage with it being on wifi all day and not being under fluorescent lighting and more standby than usual.
Edit: also, SOT has been so low today that it isn't even showing under the battery consumption list. So yeah, today has been very atypical. Lol.
I'm going to spend this week using my phone like normal, but having auto brightness on one day and off another. I'll report back here with what I notice, as well as some screenshots of battery usage.
I'm curious to see if there really is any change in battery consumption.

I don't think it's the sensor, it's how high the brightness goes. The sensor is just a small lumen counter. However, Samsung cranks the brightness really high to keep the user experience positive. It's Samsung's brightness that kills the battery, and has nothing to do with Lollipop or KK.

okay, i did something else and actually help me a lot:
Settings--->General--->Security--->Trust Agents--->Smart Lock (Goole)--->Off
And did what you guys talking about the brigthness and now i have 21 hours left!

You can bring any Samsung device to any BestBuy and they can help out by reflashing the phone and calibrating the battery. They also can help with any consumer, enterprise, and prosumer related problems. Most techs are awesome but there is the off chance you may get a bad one though. They are there to troubleshoot issues and work directly for Samsung and not best buy so they are supposed to know the phone and tablets by heart.

Never understood some people's philosophy on extending battery life.

I've read a lot of posts complaining about battery life, and other posts about users suggesting ways to improve battery life. I've read stuff like, disable LED, haptic feedback, lower volume, lower brightness, LTE turned off, underclocking, turning off sync, live wallpapers, etc, etc. To me a lot of people are crippling their phones. If your battery can last you 10 hours, that's enough because you'll probably be somewhere you can plug in. What's the point of being able to go for 20 hours when you'll probably have the opportunity to charge it before then? It's better to have and enjoy all the features.
Maybe somebody can chime in and give me their point of view.

I agree. I would never want to sacrifice a feature just to extend the phone's battery life. Instead I use a custom rom that has all the features (and more) and 12 to 18 hours of battery life.

Part of the issue is a sociological thinking pattern between wanting "more" and needing it. Depending upon the type of lifestyle you live, sometimes, battery life is of dire importance to have if you're constantly migrating around. But I agree, some people who aren't in that sort of disposition go overboard with it.
I just bought a bigger battery :good:
I agree wholeheartedly. If your battery is lasting you through your day (which mine does, and more) then why try to conserve it?
Yea its funny stuff people complain their battery only lasts 20 hrs but yet they want it to be able to do everything a computer can do and more....
Sent from my SGH-I747M using xda premium
The only conscious effort i made to extend my battery life was to undervolt the CPU a bit, but this was more for the lower temperature advantages with extra battery life being an added bonus. Beyond that i turned off things i dont use like BT, no need having something running that i have no use for. Overall i was happy with the stock battery except for any kind of heavy video or game usage which drains it pretty quick - solution : bigger F'n battery :highfive:
i agree that some people seem a bit obsessive about it. but we shouldn give bad battery life a pass either. hopefully we will see some sort of advancement in batteries to have better battery life while keeping them at a decent size.
i was kinda worried id have horrible battery life with the S3 being that its LTE. my last LTE phone was so bad it would die after 8 hours idle.

I keep the brightness to the lowest setting anyway, but I do all of this because I go to school fairly far from my home, and I'd like to be able to play games on my phone without wasting 5% battery every 15 minutes. I haven't switched power saving off since I bought the phone.
Stock ICS on my S3
I bought the extended battery because I like playing games from time to time and I don't want tl have to worry about my phone dropping 15% after playing something for 5 minutes. Like someone else said earlier. It really depends on the kind of lifestyle you live. I for one don't mind having the extended battery on my phone but I do miss how light it used to be.

How heavy is it? Does it fit in a case?
For me, and I want as much battery life as possible to avoid those situations where there is no way to charge you phone even if that only happens 1 a month or less.. As a parent I can't just let my phone die on me... I always need enough to be able to take or make that important calls/text. My goal is to have at least 20-30 hours of battery life per charge.
I think the only major feature I've given up is live wall paper. Other then that, it is just disabling other unused apps like gtalk, talkback, Google bookmarked sync. As well I've uv my phone as much as I can and run a 1350 max clock speed. I really don't see any major dip in performance as long as you do it right . I do use Tasker to disable syncing globally when the screen is off and make sure it automatically disable bluetooth after 10 mins once it disconnect. Also I have the Y5 app to automatically toggle wifi based off my network location. The most useful battery saver I've found is to set my wifi to only connect when the screen is on. Seems kind of backwards but it works well when very little data is process during idle rather the the phone requiring to keep a constant connection to wifi.

I'm also one of those people that closes an app as soon as I'm done with it. Use an app, press the home button, release and hold home, swipe the app away, sigh in relief. An old habit carried from my S2 Skyrocket, where getting 8 hours on stock was above average.

I have my screen brightness at 40-50 auto off.. i cant imagine turning it all the way down like alot of people say.. even when auto brightness is on it look very dull and dark at night to me.. Same thing for my tv with auto brightness.. but i still get good battery life. I am fully charged at about 6pm i use it till bedtime and use it for my alarm.. get up 4 am and when i get home at 2pm its still over 40%.. only thing i do is close all my running apps by holding home button a few times a day and same with ram
I work in an office so it's plugged in for the 2 hours before I leave so I have everything on full most of the day (brightness, lte...). Also, by undervolting I'm getting 30% more battery.
I think tips on increasing battery life like turning off lte and brightness are for people who can't plug in throughout the day or for emergency situations when you want to get the most out of your phone because there's some reason you can't charge.

I get anywhere from 12 - 23 hours depending on whether I'm at work or off. I can live with that...but there are situations where being unreachable poses a problem.
So, to deal with my phone addiction, I got an original replacement battery. Always have it charged and on me. When the phone shuts down, pop in the replacement and your done. About a minute without a phone. This way I don't have to UV, worry about brightness, WiFi, Bluetooth, etc...
I can't deal with the bulk of an extended battery.

30% more battery by simply undervolting? I think that's quite an overstretched statement. How is that even possible?

Its not possible. Not by solely UVing. The sole purpose of undervolting is so that your phone dosent overheat when running high clock speeds. Saving battery is just a perk. You might save a few percent with the undervolt but nowhere around 30%. But don't take my word for it.....

[Q] Initial charge?

I hate to be the guy that asks this, but I just want to make sure as from what I understand this is different from phone to phone. From what I understand, Li-Ion batteries, like the GN2's, do not have a memory effect of any kind? And thus all battery calibration rituals and nonsense are entirely pointless for this handset?
The reason I ask is because I wasn't able to charge the device to 100% before use like I was always told to do with new phones. My device was turned on and used until it drained to around 10% at which point it was charged to 100%.
Now, after 2 weeks of use, I feel that my battery is not as good as it should be. I'm barely able to get more that 12 hours. I'd be happy to post some battery graphs in the morning.
One last thing, if I did mess up my battery, or if my battery is messed up or less functional than it should be, would buying a new battery fix all my problems?
Youvare right. All that calibration stuff is nonsense.
I have never charged my phone to full before using and draining the battery and my phone still lasts all day on mostly heavy use.
Could you post your batt stats?
Sent from my GT-N7100 using xda premium
Today I ran my phone with the "lowest" possible settings, that is lowest brightness, CPU power saving, and no haptic feedback. I did not turn off wifi. Doing this I was able to get a surprising 16 hours, although you can see from the graph that I didn't use my phone as much. Attached I have a screenshot of what it's like with the highest possible settings (no power saving stuff, and brightness all the way up, but no GPS). Sorry I don't have a pic of the percentages for the high settings, I never thought to do that.
What concerns me the most is this: even with the lowest settings, I'm only getting 2 hours screen time. (last pic)
What's interesting is that you would think that if I'm getting such poor screen time, there would be something else using a lot of battery, but there isn't. This led me to believe the problem was with the battery. I discovered a pretty big scratch on my screen the other day, and I have some monthly insurance plan from best buy, so I was thinking of just getting a new one. The longer I wait to get a new one, the harder it will be to set up everything again. lol
I noticed that compared to other GN2s, mine seems to wake up a lot when the screen isn't on. The awake periods tend to correspond with drops in battery and also when I have a poor signal. Could this be caused by my phone trying to look for signal and using battery?
Yes poor signal that results in the phone searching for better 3g/2g will drain the batteey faster.
Can you try using it in airplane mode with wifi only for a day and see how that goes?
Also install Better Battery Stats and after a day or so of normal usage check your partial unlocks to see if a rogue app is preventing deep sleep and sucking your juice.

Yeah it us definitely your signal playing a role. Also you have a lot of wakelocks showing up
Sent from my GT-N7100 using xda premium
Dude you have major wakelocks that eat up 80 % of your battery!
Go to application manager and remove all the apps you don't use.
K, I agree with my week signal using battery. I only have 75 apps on my phone and they're all pretty mainstream, no obscure apps. Right now im in school with 86% battery, I'm turning on airplane mode now. I have noticed however that when I clear my ram it closes like 50-60 processes each time. I am always closing my apps, but 50 seems extremely high. im gonna turn on airplane mode and see how that goes...
thanks!
Yes, you do have poor signal but that's not all. You have terrible wakelocks pal. Install BBS and monitor which apps are the culprit. It's not about 75 apps, even 2 or 3 bad apps, which have hidden advertisement going on could suck your battery flat in no time.
So first thing, install BBS. 2h screen on time is horrible!
Btw- If you're on 3G, try to switch to 2G. Difference will be unthinkable.
Sent from my GT-N7100
Thanks everyone! I'm really loaded with school work, so I don't have a lot of time right now. But long story short, airplane mode saves my battery like crazy. I started school with 86%, turned on airplane mode, and I'm at 79% right now! more later
Is it safe to say I fixed it?
3h screen over 2 days isnt bad right? Perhaps just a bit worse than what others are getting?

Galaxy Note 2 Battery Life

Hello guys.
I've been reading these forums for a few months now and find it very very helpful in configuring my device. It's just now that i decided to sign up so i can be part of this great community.
This is my first ever post and i would like to get help regarding my battery life.
Ive read a few articles about battery saving and also from forums where people usually get more than a day's worth of battery life. That got me wondering why i only get around 8-10 hours average considering i only use it very lightly as im usually busy at the office. My actual usage time range about 60% of those 10 hours when i use the phone during breaks.
Here are example screenshots of my daily usage:
Here are some details about my configuration:
Brightness set to auto, most of the time at 75% level
Wifi, bluetooth, gps always off
Haptic feedback set to minimum
Mobile data always on and set to WCDMA only, area where im at is usually weak peaking at 2 bars of H and H+ signal strength
Gmail set to push notify
A few apps and widgets set to sync after every few hours(accuweather, flipboard)
Ive been considering getting an extra battery because of this but i really want to make sure first whether i could still do something or whether im doin something wrong thateads to the battery draining too fast.
So please if you have any more tips i could use, please help me out on this.
I thank you in advance.

Their battery lasts whole day long. It means that they get 10 hours of screen on time only. Not 24 hours.
Sent from my GT-N7100
Yeah. But in my case the 10 hours is the total life of the battery from the time it is charged until it dies. I'd be lucky if i even get 4 hours screen time out of it.
Do you have an idea why this is so?
Im guessing its because of the weak signal where im at and the fact that i set my phone to search for WCDMA only. Although im not sure whether this is really the culprit. I'll try setting the network mode to auto for now and see if anything changes.
Sent from my GT-N7100 using xda premium
Looks like it.
Try better battery status.
Sent from my GT-N7100
Well after i changed it to auto it improved a bit. Its currently at 14% after 11 1/2 hours with 4 1/2 hours of screen on time. The phone stayed on full edge signal for most of the time (which kind of sucks because internet became painfully slow on edge).
But still, i think this is far too short when compared to those who can get it to more than 24 hours battery and more than 10 hours of screen on time.
Is it possible that i have a defective battery?

Do you have locations services and etc (all 3 options) checked in the maps settings?
I don't get near as good battery life and my phone spends a lot of time awake. This appears to be do to google maps constantly updating my location. I would turn this off, but then i would loose google now functions.
Any help would be great.

I have only two of them checked(Use Wireless Networks and Location and Google Search). I have GPS disabled. i only turn GPS on when i'm traveling to an unfamiliar place which is not too often.
i got exactly the same problem, whats your firmware?
since i updated the phone to 4.1.2 the battery drains alone, every 8 hours it discharges 25% without using the phone, i am lucky if i get 5 hours of screen. The android os is the one draining all the battery in my phone. On 4.1.1 i could get 7 hours of screen time with 20+hours overall.

I can't compare mine to 4.1.1 because when i bought mine it got updated to 4.1.2 after a few hours.
having to charge at least two times a day really negates the otherwise great features of this phone.
I really hope we figure this out. I'll try UtkarshGuptas suggestion using Better Battery Stats and let you know what i find out.
I did they and found Google location services is the culprit.
I'm am referring to the locations services found under location setting in the actual Google maps app. I believe turning of location reporting may disrupt Google now features. Google locations devices is reading out as the main reason for nine consistent partial wake locks on better battery stats.
I'll try turning these features off and awe how it affects battery life and Google now tomorrow.

after doin some tests with bbs i found the wakelock is mhl_wakelock,
First off, forget all the battery programs. Factory default your phone and add an apk at a time and use. You'll be able to tell what apk is the problem with a lil testing. Slow process yes but pretty straight forward and to the point. I do have a Note 2 and have no battery issues being rooted and having tons of programs, etc. Basically, I use and abuse my device as per my job and still get a day and a half out of the battery.
People who can get 24hr coupled with 8hr screen time most likely have their phone on low brightness and on WIFI not data.
I got a new battery and its still lasts the same as the other. Yeah it may be because of the mobile data always on that eats up my battery.
Problem is my data connection is my primary internet source i dont always have wifi hotspots. So i might just have to live with the short battery life or learn to turn off my data when i dont need it.
I'll still try looking for other things that contribute to the battery being drained though.
Thanks everyone.

I have GPS disabled, auto brightness (but fairly high level) and that improved battery life quite a bit. I then changed kernel to NEAK kernel, reduced the voltage levels for the CPU and that further improved battery life. I can get a full 24 hours on one charge and with normal (?) usage). With the new kernel I can also modify the charging current to a slightly higher level which reduces the time to bring to a full charge.
All in all not too bad but to expect more than 24 hours is unrealistic in my opinion as it is a big handful of electronics!
Not sure what you guys are are doing different. This is my first full month with my note and the battery is a beast. GPS is enabled at all times but all other syncs are disabled. That's just from previous experience. Sync will always drain the battery. So mine is off. I went as far as removing all the extra chargers around my office and home. .now I only need one. And I alsi don't see a need for an extended battery unless I'm going to be away from civilization for a few days. By the way..that was the only time I've killed my battery..kinda. see screenies
--I forgot about brightness- mine is set to 50% and 4G/LTE ..if the device is always searching for it, it will kill your battery. I turn it off at the office as much as I can.

Using dark backgrounds really helped the bettery life for me. I use a dark wallpaper for touchwiz, whatsapp, and also carbon as my twitter client.
Using Perseus kernel also helped because it doesn't ramp up the cpu as high as the stock kernel.
Wanamlite rom.
Brightness set to lowest at home. 25-50% when outdoors.
Two MS exchange emails set to push.
I use wifi all the time unless it's not available I switch to HSPA+. what a waste of a paid data plan
Google now disabled because it's a battery hog. location services kept on though.

battery life

hey all, recently my g3 has gotten terrible battery life, when it would usually take me through most of the day, it now only gives me like MAYBE 12 hours with less than 2 screen on time. today, i pulled it off the charger at 1230, by 4 it was down to 54%, and after 8 1/2 hours of sitting(i was at work) it was down to 15% and then it was dead less than an hour later. i'm unrooted(was rooted) and on the latest ota, i've done a factory data reset, re-rooted and unrooted and another factory data reset. it's just weird to me because about two weeks ago my husband's g-flex wouldn't hold the data connection, dropping in consistently for two weeks(bad enough that t-mobile sent him a replacement unit, and eventually put him in a note 3) and all the sudden my battery life went from decent, to complete crap.
You are having some major wake locks. Check your apps for "kept awake ". Usually Android os has a big number but dont worry about it. Here are my battery stats for reference.
Let us know what you find out and post screenshots of any abnormalities.
Edit: ive had bad luck with battery logging apps draining a lot of battery and not letting the phone go into deep sleep.

Here is mine. Bluetooth is on from the time I unplug till I plug it in at night going to bed. Wifi is off during the day, so I'm on 4G LTE till I get home and turn data off and wifi on. So wifi is on for about 6-8 hours a day. I always typically keep sync off. Ill turn it on a few tomes throughout the day for a few mins to pull any emails and what-not, than I turn it right back off. It drains a lot of battery on mine just talking with apps trying to pull data from them constantly.
Location is also usually off until I need it. Today I had it on all day.
My screen brightness when I'm away from home is usually anywhere from say 60-95%. I HATE auto-brightness, just keeps it way to dark.
I also use greenify, and I have clean master auto clear memory upon screen off. So when I turn screen off, all apps I selected hibernate via greenify, and memory clears with clean master.
I'm also using trickster mod, and have a few kernel tweaks to smooth out the notorious G3 stutter which was from a thread on here. Lag solutions I think(ill grab link in a min) via Heisenberg's settings. Very stable and runs like a champ!
I am using g3 tweakbox, nothing fancy going on though or crazy.
Also, I do have seeder, which I was using before the trickster kernel tweaks, and it was working great, but I'm trying the trickster settings for now.
I HIGHLY recommend using the trickster mod kernel settings heisenberg suggested in his his thread. They are extremely stable, it makes phone snappy and very smooth, and I swear it made my battery life much better! Give it a shot, I swear you'll love it.
Here is lag solutions thread, 1st post is the kernel tweaks I use w/ trickster mod. It did help battery. Give it a shot, if it doesn't help you, or makes things for(which it wont, its very stable) you can always undo them just as fast and easy. Do all of them though, and do exactly, don't change numbers yet(if you're very comfy with it and do k is what you're doing with it), just give those a shot.

Thats a medium/light use with mostly talking on the phone and listening to music day and i have a follow-up for it. The pics are after 48h of use without charging.
Coming from a Samsung galaxy s3 im really impressed with the battery on this phone.

How do you have less screen on time after 48 hours than you did at 23?

Because that screen shot of the screen on time is from a different day. You can see that if you look at the time/date and battery %.
Sorry about the confusion.

Hows your signal strength? Having crapy signal drains the battery a lot.

didn't even think to check it...you'd have thought that would have been my first instinct with the issues my husband was having with his g-flex...but, battery life was my only issue with the phone, and it's up to where i'm content with it now, but in answer to your question -87dbm
Ok so I did a "test". I had bad signal- 1 bar 4g and it would hop to 2g quite often. In about 2h i drained 70% battery with tune in radio and the screen turned off. I couldnt screenshot it because my phone died :banghead:
My guess is that if you are working somewhere with crapy signal and you have push notifications coming in often it would kill your battery.

[Q] Battery drain when idle

Hey guys,
Wanted to know what your experiences with battery life were like.
When I go to sleep, I switch off wifi, bluetooth and data. When I woke up after 8 hours, the phone had lost 7%. Seems to be quite a high number for it being dormant.
In battery settings, the 'Phone Idle' option was top of the list for battery drain.
Anyone else experience battery drain here? What have you done to help improve it?
Cheers.
What's your reception like?
Install better battery stats or some wakelock app and see what's keeping your phone awake

Don't you need root to use better battery stats? Phone hasn't been rooted yet.
Signal strength is decent, not full bars, but close to it.
My last 2 phones (N5 and OPO) have had really good drain whilst dormant, so puzzling as to why this one is playing up!

My vzw was similar. About 10 hours of no use and was down to single digits.
Did a factory reset and it was better... Teach it who's boss...
Last night my phone was off the charger, at 100% to begin with, at around 2 am. I checked it at 6 am and I was still at 100%. For me, idle power usage has been very low.

Ya you need root. Goto WiFi settings then advanced and see if the 2nd option is on, (its something like apps scan for network even if its off) turn that off. If you want to stop Google play services from waking phone from privacy guard that helps a lot too.

The other thing I did (not sure if it is related) was to disable all the VZW apps and processes. WHen I did that I only lost 13% when left over night and I was down to a respectable 73% after a full day of work (though I intentionally did not use my phone much during that time)
This phone sleeps unbelievably well, better than any other phone I've owned. It flatlines very nicely
I did not manage to factory reset the phone overnight, but I did notice that the battery life whilst sleeping was incredible.
Over an 8 hour sleep, I had dropped 2% battery life. I switch data and wifi off when I go to bed. Now I'll keep an eye on SOT. Hoping to hit the 4hr mark. On my first few days, I got 2.5 hrs.

Even I Am experiencing same problem. Any one plz help
I have the International H815 and I have the same problem. Battery drains too much on idle. When I look the battery stats the Doze mode rarely kick ins. Location is off Bluetooth off and I'm on wifi. When Doze works I have really good battery and I can hit 4h of SoT when not I can barely hit 2.5h of SoT. This must be some kind of bug. Phone does not goes to sleep and Doze rarely kicks in.
