[Q] Question about rooting my Note 3 for better battery life

I've had an AT&T Note 3 since January. The phone is great but since the update to 4.4.2 I have been experience horrendous battery life, to the point that I'm having to charge it throughout the day.
I work construction and use my phone for several hours per day, resulting in 2-3 hours of voice calls and 2-3 hours of screen time. My last Note 2 and the current Note 3 used to be able to handle my workload while being unplugged from 7AM to 10PM at night.
If I was to root my phone, could I gain back my battery life? I have never had the need for my phone to be anything other than stock but I am desperate at this point.
Thanks

Rooting your phone will not result in having better battery life. What you can do is detect apps that keep your phone awake. Another method is to flash a custom kernel with lower voltage or one on which you can undervolt yourself. Be aware that by rooting and/or flashing custom recoverys/kernels or firmwares you'll trigger the Knox counter. This will void your warranty. There is no way to revert it.

I appreciate the reply. I was hoping that rooting would allow the phone to run off of custom firmware and not have the horrible battery drain many Note 3 users are experiencing after the 4.4.2 update.
I have installed GSam Battery Monitor for over a month and been monitoring it daily. I'm consistently seeing Android System and Kernel (Android OS) using 40% of my daily battery life and Media using another 15%-25%. Other than that I've been unable to determine much else. I do not play games or Facebook, I just talk and text all day.
Is the warranty on the phone one year? If so, I'm 2/3 through it and would be willing to void it for better battery life.
I have looked through all I could find before posting, but honestly am somewhat overwhelmed by all the information on XDA. This is magnified by the fact that there are many versions of the Note 3 and different carriers.
I have a N900A Note 3 and am looking to get my all day battery life back and appreciate the help.

Don't worry, it's normal to suffer infoglut the first time looking through xda. You'll get used to it =)
So you have the AT&T version of the Note III aka hlteatt or SM-N900A. You're device has a Qualcomm chip built in like most of the Note III variants out there. There's also a Note III variant which has an Exynos chip built in but I think you won't confuse Exynos firmwares with those dedicated for Qualcomm variants. The ROM threads ususally have pretty good descriptions about that. AFAIK most custom ROMs are compatible with any Qualcomm variant. E.G. any AOSP/CM ROM for the Qualcomm Note III has a unified build carried by the name "hlte". Meaning, that as long as you don't flash an image meant for the Exynos variant, you should be good.
40% for Android-System and Kernel isn't normal at all. I also use GSam Battery Monitor. Android-System and Kernel only use about 19% of the battery on my phone. Something that helped me when I had the exact same issue was to switch locating method from high accuracy to power saving. You can find this setting by long-pressing the GPS icon in the notification drawer. The location settings menue will pop up. Under "Mode" you can change to "Power saving". I'd be happy if you could report if it did work for you.
You're welcome =) Just hit the thanks button.

If I may add my own comments here:
1. you should go to note 3 ATT forum and there find proper method to root your phone, we have towelroot program that can root phone very easily without breaking knox warranty, albeit I don't know if it works on your version, it worked perfectly on mine (t-mo)
2. While it is true that root by itself won't do anything about your battery usage, many programs that really help need root
For example greenify, titanium backup or android assistant require root to disable many useless (useless for you that is) programs that drain your battery
3. I totally disagree with Nitrous that GPS is the culprit for high battery usage. It is my experience that GPS all by itself does not work at all unless the location info is requested by some other programs. Google maps for example only run GPS when screen is on, when screen is off, GPS is off also. However some badly behaving programs can keep requesting location even in the middle of night, but IMO those programs are the problem, not GPS itself. I have GPS, BT and WiFi on 24/7 and with light use my phone could last 4-5 days. If GPS was draining battery as many people think, phone would never last that long.
What you should do is go to ATT forum and find towelroot method, root your phone and freeze, or disable apps you don't use. For example I don't use Bloomberg, Yahoo, Facebook, Hangouts, indexing etc (your list may be different, since different provider) so I have them frozen (won't start up) . If I ever change my mind, I can unfreeze them later.
You can also run programs to tell you which apps use most battery, or wake the phone from sleep and then decide if you need them or not.
BTW sometimes full reset and cache clear can fix some of the problems, so maybe that should be the first step.
Once you find which program /s cause problems your phone should last whole day. I could easily get 6 or more screen hours on my Note3, unless playing some intensive games, so should you and it just took couple hours to identify and disable all the bloat and there is a lot.
I also experienced increase in battery usage after updating to KK, but I have not found a time to look over the bloat and redo my program freezing efforts yet.

I know that GPS doesn't drain battery that much. But trust me, it is very likely to cause that type of behavior. I'm in this forums since a couple of years. In most cases, when Android-system and Kernel drain unusual amounts of battery it was location services that was causing it. But not because they were using GPS, but because they kept the device awake the whole time. And there you see my point of switching locating methods. In 90% of the scenarios where people described this kind of behavior of their devices, this solved the problem. But you're right in saying that it's not a permanent solution. I agree to your first two points.

I always have GPS off and only turn it on when I need it though Android still has the higher or second highest battery usage.

I agree, root and uninstall /freeze bloatware. You'll be surprised.

Just to give quick update, after I wrote my comments here, I fully charged my phone and went to sleep. In the morning battery was down to 80% and that finally prompted me to action. I freezed some apps, cleared cache and did some "housekeeping". I don't know what did the trick, but this time overnight my phone went from 100 to 98%, 10 times better than a night before. Now, after 18 hours of some light use like few calls, couple games, light internet use etc it is still at 80%, so it's pretty much back to what I had before update. I wish I wrote down what I did to track particular culprit in my case, but it is amazing how couple bad apps can ruin battery life, but at the same time killing them turns things around so much. All in all, out of some 340 apps and services on my phone, only 21 are frozen and about 30 are stopped from starting at boot up, but are able to start later if needed.

Lollipop update giving HORRIBLE battery life

Anyone else had this problem?
I installed the stock 5.0 update (G900FXXU1BNL9) on my SM-G900F and now the battery life is terrible. I'm lucky if I can get it to last until the end of the day. Today, it's dropped to 50% within 5 hours. Before the lollipop update (again, was on whatever the latest stock version was), my battery life was superb, lasting almost two days!
Anyone know how to resolve this?

battery life
I've had my phone off the charger for less than one hour and I'm already down to 90%. There's definitely something wrong because stock lollipop unroot was giving me much better battery life and performance.

Mine lasts about a day and tbh for a device with the specs of a low end PC with a HD display and constant internet connection thats about what id expect

When your battery lasts less than HALF the time of what it used to all because of one update, something is seriously wrong.

well mine lasts a day now and it did then. so either you need to factory wipe, or you need to look at apps you've installed thats not quite optimised for lollipop

Yup, factory reset solves battery drain after LP update, I was up to day 3 without charging this morning with still 18% battery left, but had to charge up as I was going out, reckon it would have lasted the rest of the day though

Got a reply off the Samsung Twitter team to do this, so now going to give it a go. Hopefully it'll sort it because the drain is driving me nuts

Without losing root?

Factory reset will lose root more than likely, almost certainly

It happened with me but after 2 days everything settled and battery lasts at least 12 hours but still less than kitkat.

I installed the update to lollipop..... After that indeed a horrible battery life. So I installed lollipop again using kies software......

Had same experience wipe and reload greatly helped. Supposed to be addressed in 5.1.

To add yet another subjective and anecdotal experience with the new S5 Lollipop update (on Verizon, in my case), I was seeing constant Wi-Fi disconnects (~5/minute) AND battery-life that went from ~15 hours to < 5 hours, until I turned off the "Smart Network Switch". Seems all the network switching was killing the battery as well. Did a FDR and it made no difference. As long as that feature is turned on, my Wi-Fi drops constantly and the phone heats up and the battery dies in a few hours, even without use.
Would be nice to know what I'm missing now that my phone is, apparently, using the Dumb Network Switch instead.

All you're missing now the phone is using the dumb network switch, is bad battery life, constant wifi disconnects, and headaches
I turned it off a while ago, and so have many more people I read about each day - it's supposed to keep you connected to the strongest signal, but in reality, it does the opposite, plus most people only have 1 wifi connection, so it's not necessary to smart switch - and even without it enabled, it will still connect to Data when it goes out of range of WiFi, so that switch is completely pointless to start with

Yeah, I kind of figured that. Sadly, I do have two wireless-access-points in my home to handle range-issues. I had not considered that this "feature" would have a bearing on the switching between them. I did test with one of them turned off, so I could eliminate that as a possible cause before I knew about this broken functionality, and it didn't matter of course.
Does it not seem a bit odd that testing didn't uncover that a Lollipop Galaxy S5, with Smart Network turned on, would kill the battery and render the Wi-Fi inoperable?
Oh well.

You could set up your two APs with the same SSID / Encryption key and have the phone switch seamlessly between them without smart network switch enabled

But yea, it seems that there are quite a few overlooked bugs with lollipop, 5.0.2 and 5.1 apparently address a lot of them, but when we get that update is anyones guess

Wrong section, all questions go in Q&A. Not general.

please note that there are some apps are working without permission like google music i think ,

I recommend you to stay in KitKat until Samsung Lollipop 5.1 firmware arrives. At the moment I'm using XtreStoLite ROM with Toiiki kernel and I'm getting am awesome battery life, about 8 hours of screen on, cheers.

My S5 is G900H and I have the same problem. I did not like lollypop

Is this battery consumption normal?

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.

I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh my power app tells me I have 2520 too but I really dont....heh
---------- Post added at 03:12 PM ---------- Previous post was at 02:46 PM ----------
Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol

My battery is from October 2015. It's the original one that came with the phone

Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?

Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).

Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle

I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

OK I'll go ahead with this. Good guide to reflash stock rom?
I'll do several factory resets to see if it helps, but I start to think that it's black magic
Thanks

Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help

Tab S5e horrible standby battery drain

Last week I have purchased a brand new S5e, and overall I am pretty happy with it, outside of one big problem: the damned thing loses like 30-40% of full battery charge per day while sitting in my desk drawer, doing absolutely nothing. This is, frankly, unacceptable. My two-year old Galaxy Tab A loses 2% per day when idle, so I would kinda expect similar idle drain from the new device as well, given they have similar-sized battery (7040 mAh in S5e vs 7300 in Tab A).
I have tried:
Uninstalling unused bloatware via ADB pm uninstall
Turning off data and wifi
Turning location off
Restarting the thing
"Sleeping" of all the apps via Samsung's battery save features
Factory resetting the tablet and repeating the above with no extra apps installed
Tried the "Extreme battery saving" feature, but frankly, that leaves the tablet in absolutely unusable state because it limits you to like 5 built-in apps and portrait mode. Who the f uses their 10" tablet in portrait mode?!
Currently trying Airplane mode, will see how that goes, but I'm not keeping my hopes up at this point. -- Update: Airplane mode seems to have satiated its hunger for battery, but that's not really an option to keep on at all times. Any other ideas?
I'm frankly running out of options here. I bought this for xmas and it's, tbh, unusable in this state. It does have the latest software update from Samsung (October 1st, 2019).
I've tried running BBS to shed more light on what's going on, and while it's showing the device is spending nearly 50% of the idle time in "Awake (screen off)" state (compared to 2-4% on my tablet and phone), but neither Kernel nor Partial wakelocks show anything egregious. And normal battery stats are about as useless as you'd expect, too.
Currently considering taking it back and asking for a return or RMA, but figured I'd ask here first, maybe one of y'all has encountered the issue and by chance knows what's the problem and how to fix it.

You need to take an idle log with BBS and post in the BBS thread asking for some analysis.

Remind me, how do I do that?

Naptime by Francisco Franco will turn off Wifi / Data / GPS when the screen is off, and turn it back on when the screen is turn back on. Works best on Rooted devices though.
I'm using Lineage 16 on my Tab S5e, I generally get somewhere between 7-8 hours of SOT, and go 5-7 days between charges. I use Naptime on all my tablets have for a long time. Found it doesn't work as well on cell phones. I haven't paid attention to what my idle drain is, but overall my battery performance has been excellent with Lineage.

The BBS thread has all you need. Read it there...

I have figured it out.
Turns out, the tablet has some issues with the provider's sim card and plan. I got internet-only plan and it does not allow for neither outgoing nor incoming phone calls. And my other tablet has a normal calls+data plan. When I swapped cards between the two tablets the drain issues also swapped! Except the older one wasn't draining nearly as fast, but still noticeably enough. While new one only lost 1% overnight.
So looks like I will be staying with my old plan, maybe upgrade it a bit. Oh well, no big loss, but mystery solved.

S10+(SM-G975U1) battery life went bad

Does anyone know that is wrong with my phone?
the standby battery life off the chart
i can get close to 9h SOT stright no problem,but if i leave it on standby i can't even get 16hours out of it
no warm,hot or something like that
i thought it was the battery but it is still the same after replace the battery
i've try anything i can find on internet
1.Disable AOD
2.Reset network setting
3.airplane mode
4.factory reset
5.screen resolution
6.adaptive brightness,adaptive power saving
7.reflash firmware
8.replace new battery
9.switch it off for 24hours(not even lose 1%)
i'm ran out of idea now
if anybody know what wrong with this phone please help me
sorry for my english ><

You might need to take it somewhere and have a tech look at it or contact Samsung on it or claim warranty with Samsung.

See if it does it in safe mode.
Probably a rogue apk(s)... a software issue.

okay i'm going to give a try on safe mode

it's still there losing a about 15% over 5 hours on idle.

Same on my note 10. Battery live just went bad over nigh, exactly 1 year after I bough the phone. So I guess this is build in to make us upgrade to the next gen phone. I won't even waste my money to replace the battery because I know it won't make any difference. Typical $am$ung

I'm running on Pie with a 10+ so you may have different issues/solutions. One of the big reasons I never upgrade; I have this phone optimized, it's fast, stable, reasonably secure and I like it. Took a lot of time to get to this point.
Lol, I'm still happily running W7x64
Probably a Google apk; Backup Transport*, Google Services Framework and Google Play Services are known offenders.
Try clearing their data.
I package block the first 2 and use Karma Firewall to block GP Services except when I need it for gmail or gmaps.
In Developer options look at running services.
Also in the same look at Standby apps; all buckets should show as active. If not then power management** is active, disable all power management; Android will manage it's self nicely.
Enable only the "Optimized" option for display/cpu and fast charging in Device Care.
Use the factory load version of Device Care if on Pie. Firewall block it though after which use it's system cache cleaner.
Download Galaxy Labs Battery Tracker from the Galaxy store.
Download Karma Firewall from Playstore.
Consider using this: https://www.packagedisabler.com/
*turning off backup Transport in goggle settings doesn't stop it and Framework is a dependency of the former I think. It needs blocked too and will still show as running but at a very reduce amount.
Occasionally even when blocked all 3 need their data cleared to stop excessive battery usage.
**track down the roque apks one by one and deal with them without using power management options.

i completely agree with you
there no point replacing the battery like i did
Li-Ion/Li-Poly can't go bad in just 1 night unless it blow up or something
even my previous note 5 battery can take charge day in day out for over 3years without needing a new battery.

i wish i can downgrade it back to pie and stay there like you did,but now i'm stuck with Bit 4 firmware can't even roll it back to OneUi 2.1
now i'm going to give a try to disable those stuff like you said xD

Avoid charging to 100%
Avoid draining below 30%
Never charge battery if temp is below 60F and especially if freezing or below.
Ideal charging start charging temp seems to be about 80-90F
Keep battery temp below 100F whenever possible.
Shut it down or cool it if battery reaches 105F when using it.
Li's like small frequent midrange charge cycles*.
I run between 40-65% normally and fast charge it 3 to 4 times a day.
A charge takes about 10-12 minutes.
I'm at over a year and not seeing any detectable deterioration yet.
*this can extend the battery life by hundreds even thousands of full charge cycles.

Live and learn. Play with it and sort it out.
You could always get it flashed back to the original firmware if worse comes to worst... hopefully that won't be necessary.

agree,this will reduce the stress on the battery except on Note4,that phone just keep asking for new battery every
6-12months no matter what i do.
for me personally i just use it as day in day out like most people do course i don't mind replacing the battery every 1-2 years as long it works the way it should,i mean not the way my S10+ does right now ><

I haven't been a saint with the 10+'a battery but the insults add up if you do it every day.
Likewise being conservative with the charging and temp parameters should too.
It will be interesting how long this battery lasts as I use the phone a lot.
Accubattery to spite it's faults is a good monitoring tool. It's charge reminder is handy and it's milliamp overlay has been useful.
It also logs charge/discharge milliamps and times which is probably the best battery indicator.

speaking of discharge rate,may i know whats your?
mine was like 100ma-150ma on idle off screen thats pretty high even compare to 3 years old device

Disable Android updates. Only update after others have given feedback and you have more to gain than loss. Once you update you may well need to start this witch hunt all over.
Androids are fun to play with... go to it

noted,will do
do you recommended me to rollback to 1st 4 bin Nov firmware or just stick with current firmware?

Depends what you want. If not sure, play with this one for a while.
I'm still running on Pie on my 10+ so I don't bother looking much at updates.
I'm not pleased with Q though so it's a no brainer to stay with Pie. At this point I have near zero issues, it's fast, stable, it does all I need it to do and runs the apps I use well.
