Battery life worse after root. - Galaxy Note 4 Q&A, Help & Troubleshooting

I'm running simplerom on my n910f note 4. I've noticed lately that my screen on time is considerably worse than before.
I'm reaching maybe 4 hours now sometimes less, where as before I used to reach 5 and a half, pushing 6 hours.
My phone deep sleeps well with greenify and everything but I'm just wondering why my phone is performing so badly now?

AFAIK simplTEAM has done and still doing a great job with heavily debloated TW ROM. Its kinda strange though you should check the battery stats with Betterbatterystats... Xposed based mods could also be a reason for batter drain (if u r using xposed). Or perhaps simplROM team had intensivebatterymod in their V3 ROM (for N910C) you might wanna check their ROM thread for the same.

Battery life decreasing...

Ok, so I've had my SGN for little under a month for the first few weeks I had it I was getting great battery life, almost 6 hours screen time full day of battery etc.. Then I rooted it using one click root because I wanted some more access, since then battery life has seemingly been slowly getting worse. I have tried changing back to stock roms and custom roms, I've fully discharged the battery and charged while it is off a number of times but I'm down to 3 hours screen time and can't get a full day out off it anymore.
Is this something to do with the way I rooted, what can I do test and try and get back my battery life, this is the main reason I got this phone..
It's hard to say if it was the first update I installed/rooting or something wrong with the way I'm charging but it's certainly decreased even on a stock ROM without installing anything..
Anybody else encountered this?
Check battery stats and show us a print screen

Going to try latest firmware and just bought Odin mobile.. Hoping that'll fix it.
Won't let me add a picture says I don't have permission.. Sigh.

I have the same "feeling" with my Note. I have installed System Panel to monitor usage but I can't find anything specific that seems to be sucking the power. But it certainly "feels" like my battery is draining faster than before.
It's probably as the phone gets older, you install more & more Apps. Some of these are probably working in the background sucking your battery.

Even with a clean stock rom, it doesn't seem as good as it was without root or any updates.. Wish I remembered what the phone came loaded with, I'd give that a go..

Try Rocket Rom v17 or latest XXLA1 firmware and your battery life will come back even better than before, just me
Same "feeling" here! I will try LA1 firmware....
So I'm currently sitting on 4.30 hours screen time, 15 hours uptime with 20% battery remaining.
Running la1 firmware and la3 modem, been using stock browser. Taking lots of photos with flash too, so I think this combo has rectified my issues but I know there's more potential as this is roughly the same stats I got on my dhd, although that was underclocked and tweaked to the clappers.
Faith is resetored in my device, hopefully it improves.

Bad battery life on all phones? A curse?

Hello, so okay I agree the title is a bit too dramatic but I'm veryyy frustrated, so basically I've owned three android smartphones so far:
Samsung galaxy grand prime ve
OnePlus X
OnePlus 5
(a steady increase in specs)
And I have a question: why can I not get reasonable battery performance on any phone? On my oneplus X when I bought it, for the first few months I used to get 2.5 SOT and then months later I started getting barely an hour (45mins). No matter which roms or kernels I flashed, it made no difference. Battery saver on? No difference Greenify on? A small negligible amount saved...
Infuriated by this I finally came to buy a OnePlus 5 which I thought would put an end to this. However here I am, full of my battery saving habits still in me (which I have done so much research on to make sure they don't make it worse, trust me, I could write a battery saving wiki) and with a draining oneplus 5 in my hands. I've tried different roms and different kernels but still the same bad problem : a DRAINING BATTERY... I can get through a day with 3hrs SOT if battery saving mode is turned on but with a normal stock OOS I could never. I don't understand... I've tried BBS and GSam to try and find the source of this and still nothing. So I have resorted to the unofficial RR which comes with Lighting kernel which I have underclocked and use with battery saving mode on (not android's, ex kernel manager's one). So I have finally turned to xda so someone may be able to help me.
Cheers
Ps: I don't believe I am a target of the NSA and I have a special phone that is customized to track me...
I'd be looking at the apps you haveinstalled... Sounds like there's something running in background eating away at your battery life...
Or it's an energy vampire living in your home....
I am getting radically different battery performance with this phone day to day. One day it'll get a solids like 6.5 hours SoT and others I'll get like 4. Various issues it seems. Shouldnt be that hard to get consistent battery life.
Agree with above. Only common denominator here is you / your apps. But, stock+magisk with franco kernel and the app naptime is enough for me to get 5-7h sot out a full battery, but usually it's half full when I go to bed
You've mentioned that you tried many things to resolve this but I'll go ahead and tell you the things I use to make my battery last a little longer (hopefully there is something useful for you)
- Greenify with Magisk Module
- ForceDoze
- Location almost always on battery saving mode
- Force Doze for Google Play Services Magisk Module
- if WiFi is on, data will be off, and if data is on, then WiFi is off
- Bluetooth is always off if nothing is connected to it
- brightness is kept relatively low/halfway at most, the majority of the time
Running unofficial RR with Lightning Kernel v11 (1000hz version)
All this combined gives me roughly 9-9.5 SOT (about 140 apps installed)
If I forgot to mention anything, I'll edit it in here!
I've been very careful with my apps and I can't see what could be causing, I've tried third party Facebook apps instead of the official one for example and there's nothing strange installed.

Try with basic steps. Factory reset then:
1) Have totally stock OP5 - no "battery saving tricks", no apps. Run a bit. What is SOT? If less then average of 5-6 hours - either you have a "curse"/NSA tracking you or defective hardware.
2) Install your "battery saving trick" one by one testing after now and then. Are there any improvements in SOT? If yes, then write your wiki page, share your findings . If not, write your wiki page and tell us what application is a culprit.
3) Rinse and repeat until no more application left to install or you got bored.
I'm getting incredibly poor battery life after the latest update. I haven't let it fully deplete yet so maybe it just needs recalibrated?

There`s alot of sstuff activated on your 1+5. Try turning it off and check the SoT afterwards. Also some people were complaining because their Android-System was consuming way too much energy.

Oops, I meant to follow up on this. Android System and Google Play were causing a lot of wakelocks. I cleared cache in the Google Play and Google Services apps sad now I'm back to my typical 6-7 hours SoT.

Best Rom to install? (official samsung marshmellow slow and batt draining)

Whats everybody's recommendation for what ROM to run on the note 4 (mine is A snapdragon). I was using Dr Ketans rom, and that was all really good - fast and snappy, good battery except video was not GPU accelerated! And was a battery drain, or having playback issues. That was the only issue i had with it.
So i went back to the factory Samsung Marshmellow android, but immediately everything was laggier and slower, and the battery drain was horrendous (from 5hours SOT, down to 2hours SOT). Im almost %100 sure Samsung intentionally made it that way to force users to upgrade. But i dont want to let them win! since these phones have removable batteries to keep them going for some time yet!
So what is everybody elses using? I really like to use the pen for taking quick notes which may rule out lineage?
Thanks
Uhm, I don't get 5 hours of SoT on any rom, maybe 3-3.5 hours if I'm lucky. Did you manage that on "Dr Ketan's rom"?
On terms of usage experience, I'd recommend Resurrection Remix.

yeah i was managing 5 hours SOT and i think once or twice hit 6 hours. May of been on kit kat before i used dr Ketans Rom, but all i know is going back to samsung stock Marshmellow was a big mistake.
I should have some screenshots somewhere to show those SOT times. I really ran things bare minimum though. I will give Resurrection Remix a go thanks.
Anyone else have any feedback? please share.

Best ROM so far for OnePlus 2 or Solution for battery life

Hello guys. I know that this is a very common question not just in OnePlus 2 forum. I read some posts of this, tried, but no success. So far I've tried couple of ROMs but battery life is so disappointing. Best shot was RR ROM 8.1 official with BB kernel installed. After system and kernel installed, I've done a wipe of data. I wanted to make sure there is nothing except system on my phone. After that, all necessary apps I use. That was operating very good in few days. But recently, out of nowhere, battery life is awful! Over the night, with no use and battery saver turned on, I loose more than 20%! I know that I haven't downloaded any additional apps after first days of installation, I haven't changed any settings since first day... I added fingerprint lock 2 days ago and yesterday I turned it off. So What is going on??? Phone is not overheating, seems like there is nothing in the background running to drain battery.
If you know what could cause the problem, it would be very helpful. But I'm also opened for installing a new ROM, kernel...
Who is here with good battery life? Gimme some advice! Btw, I don't care if it's N or O, or anything as long as it's operating well, reliable and no bugs. Thanks!
That's probably a battery issue, install AccuBattery then see how much health your battery have(requires few charges).

I reached (haters gonnah hate) best battery life on lineage 13 with boeffla kernel (zanezam's uber builds, use some battery safe profile from profile thread or make your own), amplify, greenify (optimized accordingly to the corresponding thread, with xposed) and NO GAPPS. Get about 3 days with SOT of 2-4h or a sot of 6-9h on 1 day (on an old oneplus2, no gaming). You can also use dualbootpatcher and a second, battery optimized (but lagging) ROM so you can switch when you can't charge your phone for a longer period of time.

I did, really awesome app but I'm not sure that I understand what is saying to me. And I don't think that is battery issue because before this I had a really good battery life. I'm sure that if I do a fresh install of new ROM, battery life will be great but only for few days.

Forget everything with dualboot patcher, you would probably mess up your phone.
For everything else, use xda search. Seriously, you only have to type the apps i suggested 1:1 into the adress bar and you will find it! If you are too lazy for this, unroot and go back to stock.... seriously...
Edit:
Yes, i'm using this now (lineageos13) with a self compiled boeffla kernel (uber 8, camera focus fixed on 6.0.1 roms), greenify, amplify (own build), xposed (needed for amplify, greenify works better with it) and no GAPPS (= google apps--> no playstore, youtube, etc--> draining battery as hell, idk what they are always doing in the background...)
My boeffla profile: 3 cores 1250mhz max, big cores disabled, battery extreme governor, system and my apps (whatsapp, telegram, 9gag, browser) work fluently (they start up a very little bit slower than before).
Battery profile is same but with 2 cores 675mhz, still only few microlaggs (you have to disable all animations in developer settings), internet browser is slow (use a lightweight browser, such as firefox focus) apps open up slower but aside from that the phone is usable. If you're interested in the kernel and my profiles, please tell me (you still have A LOT of work to do by yourself, such as setting up amplify and greenify, disabling (system) apps you don't need, adjusting everything for your needs, deny unnecessary permissions on app ops xposed, etc).

AOSiP it's a rom - Android Open Source Illusion Project
NGK it's a kernel - No Gravity Kernel
SOT - Screen On Time

Results can vary. As someone who flashes way too many ROMs - its an addiction - I currently use crDroid Oreo as my daily. I also flashed the blue bolt kernel. This seems to give me good battery. I do have a rooted version of the stock ROM I flashed in twrp backup. Just in case. With crDroid also backed up I can move quickly from one to the other in about ten min without losing all my settings. It is a good idea to occasionally do a fresh backup of one or both since apps added or deleted or updated and any changes you've made since last backup will not be kept otherwise.

Do you know dualboot patcher (google it )? Very nice opportunity to have multiple roms installed on the device (which even share the data for specific apps--> u have all your wa chats from one rom on the other, directly after reboot). Wouldn't recommend for people who can not restore a backup over adb (unexpected things can happen, but way better than always saving and restoring a backup)...

If you don't mind for a worse looking screen quality, you can use terminal emulator (with root), do a backup in TWRP(ALL partitions!) then type (hit Enter after each line):
"su" (grant root if asked)
"wm size 720x1280" (for 720p, it looks about the same as 1080p, u can also use 480x854)
"wm density 300" (200 for 480x854)
Then u can lower your cpu frequencies until it lags. (and disable system animations, my phone works fine at 480p with 2 cores at 768mhz max freq) will post sot/running time (without charging) when i have the time to test.

About battery SM-N910U

Hi, i have SM-N910U device and the original new battery. But, why my battery draining so fast? Currently i using MM 6.0.1 official. Not rooted device. I’ve done lot of things to keep battery stable. But it seems not working. The battery drained so fast. This is malfunctioned of seri U or what? Thanks for the answer
What do you mean by "original new battery"? Do you mean the original battery that came with the phone? Or you have recently purchased an "original new battery"?
If you have recently purchased a battery it is almost guaranteed not to be an original Samsung battery as they do not make them any more - it is probably fake. Buy a RavPower battery and see how it goes. Same if you're still using the battery that originally came with the phone - get a RavPower. You might also want to try a factory reset and set your phone up clean again - this made a big difference to mine about a year ago when my battery was draining fast.

Three possible curlpits: Your apps, the battery, or the firmware
Battery—fake battery will die fast, according to what others say
Apps—some apps are battery hungry, so find a way to hibernate those with Greenify or Hibernation Manager
Software—Android 6 is the last and worst update for performance and battery life. While it's on KitKat (4.4), its battery life was awesome; fast forward to Lollipop (5.0.1–5.1.1), from 12 hours of Screen On Time (SOT), it got decreased to 8 hours; and fast forward again to Marshmallow (6.0.1), it became from 8 hours to 3 hours. No matter what kernel or battery-saving methods you use, it's futile for a firmware that rots a powerful phone. The only way to fix this is by either using a custom ROM (Refined Nougat, Note 5/7 ported ROMs, etc.), or downgrading your firmware. (Installing KitKat with the latest bootloader prevents you from downgrading).
With a new battery on MM stock and unrooted I was getting 6 hours SOT (Exynos). Dropped off now after using the battery for 18 months, but soon upgrading to Note 9 or 10 anyway.
