Battery life severely reduced!

Please can I get some assistance, I cannot for the life of me figure out what has happened.
LeeDroid 3.3 latest.
I have gone from 48h standby to 14h. During use it's depleted in a matter of hours, it's incredibly low in relativity to what I'm used to.
I was on LeeDroid 3.0.2 previously and battery life was VERY long, I loved it - going back to this version doesn't help and the battery issue remains, and therefore it also remains on the newest build.
Previously I was running a bucket load of apps/games with normal 50% brightness, I have resorted to deleting apps/keeping tasks closed but to no avail. The Statistics for battery usage seem to look similar to how it used to be before, with display taking up a large chunk.
I tried the battery trick today but it hasn't helped. My phone has already gone to 98% (40m uptime) with screen turned off + SetCPU set at powersave/lowest mhz while screen is off.
I hope you can help, Thanks.

This does happen sometimes, not sure what causes it but a wipe and reflash sorts it out for me.

What kernel are you using? Have you made any recent changes before massive drain started happening?

Try monitor the current using current widget. If it's normal, around 1-4ma during standby, perhaps, your battery need calibrated. If it didn't resolve your problem, then, maybe the battery is dead.

I dont think this is the problem because when it happens to mine it just happens by itself after a few weeks of having the ROM installed with very few extra applications which I install immediately.

anyone know if the proximity sensor is classed under display? could be that thats stuck on. got any apps that use or used the proximity sensor? or maybe the touch screen is stuck on.
have you tried removing the SD card? see if its something on there.

Well I reinstalled Leedroid with the recommended rom and although the battery life is nowhere near what it was previously... its at a respectable 22h or so... enough to give me time to actually find a fix...
Theres no apps, nothing, just the rom and its apps so I will try it without SD card also, i dont understand how to check for proximity sensor though
Thanks

Unsolvable Battery Drain

I've been having some strange battery issues.
TLDR: Phone battery drains and warms up when in use, but not when in sleep. Resetting batterystats doesn't fix it. Closing all processes doesn't fix it. It does it on a bunch of ROMs, which were always clean installed. The usual battery saving tricks do nothing.
More detailed:
Basically, whenever I use my S3, I get a considerable amount of battery drain. I used to have fantastic battery life when I was running LiquidSmooth RC5, where I was capable of 4-6 hours of screen time in a day. Now I can only get 2 or less hours of screen time in a single charge. This seemed to start after flashing LiquidSmooth RC8, but I also have the same issue in LiquidSmooth RC9, LiquidSmooth 4.2 beta, Task & Ktoonsez 4.1, Task & Ktoonsez 4.2, Slimbean, and Cynagenmod 10/10.1. So I don't think it is my ROM.
Anyways, so the battery drain only seems to happen when the phone is in use. During that time, the bottom of the phone around where the CPU is located gets considerably warm after just a few minutes of use. Otherwise, when the phone is locked, it deepsleeps fine with no drain. It still does it even when I go through my entire process list (and cached process list) and stop everything, it doesn't help. I've tried the whole batterystats reset where I charged to 100, drained, then charged to 100. That didn't help. I do make sure to clean install my ROMS, including clearing user data, cache, dalvik cache, and formatting my /system. When I look at my battery usage, it usually seems to be Android System using my battery the most. It can also be Android OS, Google Services, and Media sometimes. I've tried a ton of fixes, nothing helps. And of course it still does it with WiFi, data, GPS and all that off.
Help would be appreciated

battery life is an issue with many different factors.. there can be a bad app, bad battery, bad rom, anything really. if your phone is having issues then maybe 4.2 isn't the best for your phone there are many different roms to choose from and many are very stable.

Running 4.2 isn't the issue, though. It does it on 4.1 ROMs too. I'm not even on a 4.2 ROM right now.

Sounds like a rogue app or widget draining it. Get better battery stats. Type it in xda search. That will tell you for sure what exactly is draining the battery. Good luck.

Maybe your battery is just shot and its time for a new one

No, all these guys are wrong. Your phone is shot. I did everything you did. Better Battery Stats, calibrated battery, changed battery, changed SIM card, all radios shut off like data, GPS, Bluetooth, et cetera, no rogue apps, deep sleep according to BBS. You name it, I done it. And no one knows why our phones are doing this.

Except two of my friends that have S3s have the same issue, as well as another friend with an S2. I don't think all of our phones are defective.

Excessive Battery Drain due to Android System

Guys please help me out...
I'm facing serious battery drain since yesterday. Was previously on ARHD 21 till yesterday...but observed increased battery drain during the night...battery reducing by 1% per minute in idle conditions...found the phone completely discharged in the morning...i thought maybe something has gone wrong with the ROm so wiped clean my phone using ARHD script...then flashed new boot image and installed ARHD 22....
unfortunately...the problem still exists...another important symptom...excessive overheating of the phone, especially near the camera...
in the battery stats section, Android System, Android OS are the top two with combined consumption of more than 70%...i have no clue why this is happening and hasn't stopped even after a superwipe and fresh rom installation....is there a more stable kernel that i can flash? please help me
Update: I moved to Blade ROM and the problem still persists...can it be that there's a problem in my sd card content?

Android System covers a lot of processes, use an app like better battery stats or gsam battery monitor to determine which services/processes exactly are causing the drain. If you've flashed a new kernel then the most important thing to do is wipe the dalvik cache, failing to do that can cause drain/fc errors in its own right.

I went to recovery and cleared the dalvik cache but the problem still exists...the phone is constantly hot and battery is draining like anything...i'm installing better battery stats...can you guide me as to how do i locate the problem using the app?

The app will give you options to check battery usage either by app, process, or partial/full wakelock i.e. what process wakes the phone up from deep sleep. If it's constantly hot then it seems like some process is constantly running or unable to stop, for example if you restore an app like facebook from a previous rom it may be constantly trying to sync without authorisation, etc.

Check out proccess and i happen same problem, but i see its problem with wifi receive signal, its forced the battery wifi have bad receive signal.
I think its related at problem hardware (wifi with bad signal), battery is very hot and turn off wifi and come normal temp.

I am having the same problem after upgrading to ARHD 31.2 battery drains quickly while I am using internet.

High held awake time and battery drain

So my battery on my phone seems to suck... I just made a full wipe clean install of ICE Rom 3.5.0 with cleanslate kernel, balanced pnp profile v. 22, magisk root and got a whooping battery loss of around 30 percent overnight!
I was using stock before and had around 20 battery loss overnight, which sucks and is the reason i wanted to try a custom rom.
My phone is already 4 months old and I did a battery diagnosis, which ended with 94 percent (which is good right?).
Can anyone please help me?
I don't have Facebook or Facebook messenger installed, turned of WiFi and Bluetooth Scan and Location Services.
And I'm using Greenify, although I didn't greenify any apps yet

What email app are you using? How have you got it synced? See how many times it wakes your device using Gsam or some similar app. This was my battery drainer (I use Bluemail). Anyway, check that out first.
20% battery loss overnight is horrible. Something is not set up correctly or is misbehaving.
Reboot your device and let it set for 2 minutes. Now go to System/Settings/Developer options and select Running Services. Everything look OK there?
I cant see your screenshot.

Yes, I lost the same amount although I had the phone in flight AND extreme energy saver mode...

I'm facing the same problem after i updated my Firmware to 2.28.617.6. My Battery Usage show 45% of ANDROID OS an 39% of ANDROID SYSTEM, I'm already tried Viper 4.1, 4.3, 4.5, 5, 5.1, all with the same problem.
I updated firmware using RUU.exe, and i already updated firmware again to 2.41.401.3 with RUU again. Same problem
I realized the problem is not with rom, all of then, stock or custom, show the same situation. Its a firmware problem with Nougat
My phone is a Unlocked version, with S-ON
Any help?

I would perform a full wipe (+data!). Reinstall your Rom freshly, and the problem should be gone.

I'm already did that, all ROM's installs i did with a clean install.
With no one third app installed, the problem persists
i'm already tested turn of wifi, bluetooth, location, put phone on save battery mode, restart all permissions
Nothing helped
The main question is thats something who did not let phone enter in deep sleep

Yeah I've got the same problem with Android OS and Android System (the wakelocks are HVDCPD_WL and NETLINK) keeping the phone awake and preventing deep sleep almost 100% of the time, which is absolutely killing my battery life.
Frustratingly, the problem is not solved with a full wipe + reflash of any ROM. I originally had the problem sometime after the stock 7.0 OTA upgrade, at which point I unlocked the boot loader, flashed Maximus HD, then the problem went away for about a month until just returning a couple days ago. I've tried flashing the latest Maximus HD, Viper, but nothing is fixing it so far.
I bet it's some kind of hardware issue. I'm almost at the point of giving up and getting a OnePlus 3.

Just sharing my experience: I tried every Sense-based ROM I could find, problem of phone not going to sleep persisted. Even tried RUU to latest 2.41.617.3, which of course wipes absolutely everything - same problem, phone not going to sleep. As last ditch attempt, flashed the LineageOS Jan 28th nightly, and the problem is gone. Phone sleeping properly and battery life is back to normal. Not sure if coincidence or what... Going to stay on Lineage for a while as it works pretty well, but will go back and try Sense again in a couple weeks maybe.

This issue started to affect my phone while still on Marshmallow, around 3 weeks ago. It felt like it started after updating an app. This is what prompted me to update to Nougat. However, the issue persisted, even with full wipes, and even with LineageOS installed.
Moving from stock ROM to LineageOS has reduced battery drain from 10% per hour, to 5%.
Airplane mode and battery saver mode makes no difference to the drain. Neither does any WiFi and GPS setting changes - I have already read about a few possible "causes".
Perhaps the only option is S-OFF and re-flash all partitions of the phone?

Running a RUU would be your best option. This will wipe the phone and restore the stock ROM (system, firmware, etc).
Have you looked at wakelocks or app usage to see if there is any unusually high usages? I had a problem with my 10 awhile back that ended up being a particular version of Google Play Services. Usually these issues can be traced to a particular app or setting, it's just a matter of knowing what to look for.

Ohio wake_lock and no deep sleep. Same issue after reflash ruu, lineage, viper... on all roms same issue and no deep sleep. I think it's hardware issue. I try to flash elementalx kernel and it fixed problem for a day, one day only. Worst phone ever for me.

How do you make a battery diagnosis?

Hi, since about a month I've been having the same issue, the kernel HVDCPD_WL and NETLINK wakelocks are keeping the CPU in use and consuming the battery charge at a rate of about 10%/hour. Has anybody got any new info on this? I read of someone that claims of having fixed it by cleaning the usb-c port, but in my case it doesn't seem to make any difference.

battery draining fast-screenshot attached

so i'm trying to figure out why my battery is draining so rapidly. I'm charging once and rarely twice during the day at this point. I'm running the latest and greatest from leedroid if that matters. attached a screenshoot for reference.
Anything else you need to help me with this just ask and I will answer. Thanks!

There doesn't look anything too bad from that screenshot. Have you got gsam battery monitor ? Try that and see what ' app use ' shows. I had a problem for a day or two on the same rom ( nothing rom related ) and no amount of reboots solved it. For some reason the kernel was keeping the phone awake 100% . Sometimes it's an app or a download or some media on the device, if it's a recent problem check everything that's been down or uploaded and any new media or app on the device. A wipe would likely fix it but try and narrow it down first. I think my issue was a play music download but can't be sure as I cleared cache, dalvic cache and data for several apps.
It's now back to usual ( 5 hrs SOT )

android system and kernel combined have 40%, they are the top 2 consumers and have the most wake locks.

That's slightly high but not drastic. There's a ton of factors for battery drain, what's the 'held awake' time versus the sleep and how much SOT do you get ?.
Another way to narrow things down is to leave it with data off for several hours to see if the drain stops.
There's dozens of options on Leedroid which could change battery life , including the kernel options in aroma . Ambient display can drain battery as can some of the ways to turn on the device.
You could try to wipe all the caches, clear data for Google apps and maybe dirty flash the ROM and see if things improve.
Maybe also try the battery calibration as detailed in other threads. There's a possibility the battery may be degrading of course, check the thread for that and see what your capacity is now.

Do you have the Facebook app installed. For some reason, I seem to notice battery drain more with some Facebook updates. I don't know what it is but my phone will easily last a day, Facebook update arrives and phone needs charging twice a day. Another Facebook update arrives and its ok again.

I think something is really wrong with the 10 lately. My battery goes down like crazy as well, I first thought it was my device and performed a factory reset, but still the same issue. Now I see that there are a lot of people mentioning the same thing the last few days.. Can't be a coincidence that my battery went bad along with others' at the same time..

i have ambient display off, i also selected one of the battery saving kernels. i had about 10 thousand wakelocks coming from powermanangerservice.wakelock this morning. the sucky part is i got frustrated and just uninstalled better battery stats after seeing that. i know that wakelock means there are tons of partial wakelocks.... it's just becoming a pain. hate my phone right now.
()after i left work) i just installed better battery stats again and i'm gonna let it sit.

Mine was bad again yesterday but back to good today. Only change was a Google play update ( pushed by google, I assume play services as it updates itself not through the store ). Maybe see if there is a more recent play services that helps you.
I thought power management services was the turning on of the screen/device but may be wrong , do you have wake gestures enabled ?

no wake gestures, honestly i disable all the bells and whistles b/c battery on most phones. and here's what i got after a days use, SOT 2:50. The important thing to note my phone rarely get's used. text throughtout the day and video on the train ride home. music. i think that's pretty basic. what're you guys thoughts?
below are screenshots from Better Battery Stats of kernel and partial wakelock.
