Possible fix for logd battery drain

I have a tip for all those who have a battery killing logd process:

I have the same problem and I hope I found the problem that is causing this effect.

I had lost 3% battery in unter 15 minutes. Now I only have 5% after 30 minutes and the main battery drain is from the display. But Ih have to say that I switched the phone on quite often to check what logd is doing. ;) And the graph is now also looking waaay better. SO...here is my "fix" that seems to help:

Check if you have the "Activity Setting" switched on under Settings -> "About phone" and there at the absout end of the list ""Activity logs" (to help improve quality and performance....") ... damn it LG, then code the stuff correctly so that it won't suck the battery empty like dracula after hundret years of sleep. ;)

If this option is active, switch it OFF. ;) Deny that you are willing to send data.

This seems to fix the logd problem. As far as I can say after 45 minutes testing. I still have to charge it fully and then test if it changes anything. But I'm quite confident that there is a good chance this fixes the problem.

Here is a screen shot of the setting: imgur.com/cZ6gzXh

Short update: 1.4% battery usage of logd after 60 minutes.
[G4 General] One Twelve:
Try without Viber. See

this

.

And can you set battery so your status bar shows how much is left in %.
[G4 General] Koostis:
Of course you can. But that's way more distracting than seeing the approximate amount.
[G4 General] sugarcos:
Unchecked "Activity logs" and reset the phone, but still "logd" shows as most consuming app in gsam battery. After unchecking "Activity logs", logd CPU usage still increased from 25 minutes to 45 minutes, so i am not sure if "Activity logs" is related to logd or not. Don't have a rooted phone to check more.
[G4 General] shinanai:
so far so good :)

Marshmallow is a disaster. I get 40 to 50% less SOT time compared to lollipop. What a shame that marshmallow is not what it was hyped up to be
[G4 General] BikerBoy030:
This point has nothing to do with lodg. I deactivated it at the first minute of using Marshmallow but the lodg sucker program drives me crazy...

Maybe another person knows what to do

Two weeks in with MM update, and battery life is getting back to LP levels that I experienced ( 4ish hrs SoT).

I had 2.5 hrs Sot after the update. I waited one week before trying a factory reset. Still had horrible battery results.

Disabling the activity logs did significantly help. But I think it just takes some time for the software to settle in and calibrate with the battery. I also noticed that many apps I previously had installed weren't optimized yet.

Today I'm getting my best results yet and each day it improves a little more.

Lots of Bluetooth streaming was included today but mostly on Wi-Fi. I also reinstalled greenify again. Might have a part to play in the improvement.

Overall...very happy with the update now.
[G4 General] sugarcos:
If you use it in house on wifi you could get easy 4 hours sot also on mm. The things change on 3/4 G and when you get outsode.
[G4 General] ozontec:
logd fooled me. After some time, the CPU usage increases. I have the bastard with Tasker under control. Every hour sets Tasker the following shell command as root:

kill -9 `pidof /system/bin/logd`

Better ideas are welcome.
[G4 General] One Twelve:
No battery calibration required with the G4.

The settling bit i've heard about. it seems a bit extreme to have to do a factory reset.

This may have something to do with it.

is there a way to get it to optimise all apps so you don't have to wait :D
[G4 General] PixelBurst:
A bit OT, but I've recently flashed CM13 and I'm experiencing ridiculous battery drain (20%-30% overnight) someone suggested to me that batterys take time to adjust and after a few charge cycles it will be back to normal but it's been 3 days now with several charge cycles and it's still just losing battery.
[G4 General] Jonathan-H:
Note 4 screen may be bigger, but better is simply not true. I've had screen issues with both note 4's I had. Samsung Amoled screens are notorious for having half the screen one colour and the other half another, same with the S6. Bottom half of both my Note 4's and my 3 S6's were all red, with the top being bluish.

Samsung screens have a wow factor for a day or two then all the problems come flooding in (You don't notice it at first). G4 screen is much better than the S6 and note4 screen due to these issues.

As for battery, I got around 5 hours on note 4, which I achieve on this when i'm not gaming.
[G4 General] Pfeffernuss:
Yes. Samsung makes the best phone displays. Universally accepted, proven by reviews and display tests. Best contrast, best blacks, most accurate colors, the works. Best by far.
[G4 General] PixelBurst:
I can't help but feel this is a little off topic, but OLED screens really help battery life with black backgrounds so that's a plus for Samsung's screens. Might be best to get back to the subject at hand though...
[G4 General] One Twelve:
Battery only needs to be 'conditioned' when its fresh. This means be able to hold charge. Usually 4-6 cycles is good. There is no need for any calibration according to the anandtech review of the G4..

You have drain and need to figure out where its coming from.

if you moved to CM then chances are you've had you phone for a few weeks already. Ben trhough many cycles ie battery is already conditioned.

Now you should have flashed a custom recovery which will allow more options. Such as wipe cache. Give that a go.

have noticed several G4 variants don't have the wipe cache option with stock, just factory reset which is a tad extreme.. Noticed the Sprint version had the wipe cache option. Whether its the only variant with that option i don't know. Wiping cache means new cache is built up so everything is in sync. otherwise there can be a conflict with the previous cache.

This is just one possiblity out of others. A new OS can have issues of its own. Are you guys monitoring nexus owners and whether they have reported any such drain and possible fixes ?
[G4 General] citytrader:
You are telling nonsense, I have the Edge+ and the screen is far superior than the G4 and miles a away from my G2 and I don't have color issues as you wrote, maybe your devices had a faulty screen, I even did a test putting a white screen and checked it in photoshop and all the screen is pure white, something I never got in my G2 and G4.
[G4 General] axl91:
Same problem here, can't get more than 2.30 sot and logd drain battery..
[G4 General] MichaelxHell:
I have the G4 with stock Marshmallow, plus Root. Battery is significantly worse, at one time I lost around 30% over night. Things seem to be a bit better now, but i'll give it a full wipe one of these days and see how it goes from there.
[G4 General] nismo929:
How'd you get root with MM?
[G4 General] PixelBurst:
Probably flashed the rooted image as that's the only way at the moment.
[G4 General] @Mir hosiEn:
How's battery at all?

Better than lp ?
[G4 General] nasosgr:
This is a 3 hour battery drain without touching my phone, with wifi open..
[G4 General] One Twelve:
5% per hour (!) It should be losing that much in 12 hours.

Anyone here did a factory reset after they went to MM ?
[G4 General] nasosgr:
I did two factory reset after i installed MM... one from the boot menu, and one through the settings.. Then i did a complete system encryption. Can data encryption cause that much battery drain?
[G4 General] One Twelve:
After the factory reset how did you restore ?

manual or from the cloud.

best is manual, install few apps, wait and see, install more etc.

if its from the cloud then a rogue app comes back and the problem is the same. MM is new and not all app developers got time to update their apps. What was working in L might give problems with M.

This is just one idea. caused by a app or more than one app.

Drain can also be because networking interface is being prevented from going into idle state. In active state it consumes more power. Why is it doing that ? maybe an app got stuck. App reinstall will fix if you know which app. or it may not because app has not been updated for MM. But if you know which app then you dont use it until it gets fixed by reporting to devloper.

or it could be an OS thing. Right now can only do experiments. I think its less OS and more app misbehaving because not up to date with new OS. Keeping networking interface active all the time and not letting it rest = drain. This drain is high so chances are its networking.
[G4 General] nasosgr:
I installed the apps manually one by one from Play. Exactly the same apps that i had in lolipop... Yeah i have to investigate now... It is not clear from the battery app wich application causes that drain.
[G4 General] One Twelve:
One way would be to check changelogs of apps you use in playstore to see whether they mention updated for MM.

This way you can find apps that are supposed to work and ones that may not.
[G4 General] axl91:
I have this drain

I ge about an hour sot even in Wi-Fi

I wished i didnt upgrade to MM and stayed on LP. Its been over a week now and the phone is ok but battery life is worst and the phone gets very warm if i use it for any amount of time WhatsApp, checking XDA via the app, browsing. If i could go back to LP i would instantly as i didnt have these issues.
[G4 General] moulip:
Using LGUP and the LP kdz firmware you can downgrade.
[G4 General] scott.deagan:
I've read every single post here, and am extremely suspicious of those saying "just wait, battery life will improve after a while". Complete load of BS, and it wouldn't surprise me if those suggesting this work for LG.

Let's not beat around the bush here and get straight to the point: LG screwed up big time. The G4 was an awesome Android handset with very respectable battery performance. On Lollipop, I was recharging once every 2 days. After "upgrading" to Marshmallow, I now have to recharge 3 times per day. My usage of my G4 hasn't changed, nor the apps I have installed. I've even performed several factory resets, and not installed any third party apps at all (I'm a corporate officer and simply need phone, email, SMS), but the battery drain problem persists.

LG have released a defective build, there is overwhelming evidence to support this. It's now up to LG to rectify the problem. Either give users an easy way to restore Lollipop, or formally acknowledge the problem(s) and work overtime to release a fix.

I've owned the G4 since it was first released in the UK and have described it as the "unsung hero of the Android world". With the recently released Marshmallow build for the G4, the device has become borderline unusable (unless you're always close to a power socket and charger).
[G4 General] kyogiro:
I have roughly the same battery life as before with Lollipop (prior to switching carrier).
[G4 General] RichardC27:
My battery life was noticeably worse after the MM upgrade until I set location services to Battery Saving mode. It's better now, but still not as good as on Lollipop. For some reason the Marshmallow update causes the GPS to be active almost constantly, which obviously causes huge battery drain. I'm still debating downgrading though, the update has done basically nothing apart from making my battery life worse
[G4 General] garytube:
same here, battery got worst. just writing this small post coasts me 3%battery life. I can't see any advantage in MM - so I will downgrade now. kinda makes me sad because the G4 is an awesome device and deserves to be up to date...
[G4 General] Essex_Hal:
Glade to see I'm not the only getting bad battery life.How do I downgrade back.I have an unlocked H815 in the UK?
[G4 General] bobsie41:
Just flash lollipop kdz using the LG up tool.
[G4 General] sparkfly88:
My radio seems to be staying on all the time since the MM update...
[G4 General] lolimstupid:
facebook seems to cause significant standby drain for me on marshmallow, even though it doesn't show up as using battery in settings.

After uninstalling standby battery drain is basically flat with wifi on... i still have messenger installed, it's just the main facebook app that seems to cause the problem
[G4 General] mat3usz:
Marshmallow Nom Nom

I have updated to MM yesterday on a H815 Czech model and have got great battery so far even with Bluetooth being enabled with a Mi Band. Mind you, I am running stock, no mods, no rooting or anything to add light to my setup. After trolling skimming the thread, I am reaching the conclusion that MM is wonderful and a great update with the features that MM promised. Yes, I am aware that this is just 24 hours use and will report as well my own usage, but after playing with it for half the day yesterday, I am smiling at the upgrade choice. HOWEVER, due to the spread out app eco-system, this changes the game as not all apps are optimized for MM yet. Will there be a time most of the apps will be? Yeah, give it a few months or a year and the tone will be different.

If battery life is that much of a hit for you and your configuration, just downgrade via LGUP and stick with LP until the battery life gets ironed out with optimized apps or contact LG and let them know. Whining here is really annoying and doesn't get much done other than people rolling their eyes (or attracting trolls). If that doesn't fit the bill, just get a (i)phone :P

I created a thread here about very low battery life and huge discharge http://xdaforums.com/g4/help/amazing-battery-discharge-t3282818/post64588690

I was thinking MM is a nice Android update with doze mode and all sorts of improvements, but I admit, as you all, that LG f*cked up.. my devicr was a beast under LP. Now everything is low, full of bugs and consumes a lot of energy.

Needless to say posting this message cost me 4%..
[G4 General] Cozmos23:
I like the MM update. Did fresh install and have good signal, fast ui and very good battery.

Don't blame LG for user errors or bad apps.

Btw. No xposed and only debloated basic Google stuff.

Yeah I have given up on MM after about two weeks of terrible battery life. Max SOT of just 2hrs but mostly 1.5hrs and tripple charge a day instead of single evening charges. Back to LP where I'm happy at 4hrs to 5.5hrs SOT.

Lets hope later MM builds have a better battery life for all. Even doze has nothing on my LP standby. 0% drop after 7HR night.
[G4 General] RogerF81:
The MM battery life is terrible...In two weeks of usage I only got around 2.5 to 3 hrs of SOT...Now back on Lollipop I get 4.5 to 6 hrs SOT, that's a difference!

Yeah, it was easy. Instead of upgrade, I clicked refurbish, it erased everything but that isn't an issue.

It wasn't in the instructions, but I searched for bootloop LG G4 (strange, there are a lot of people with it haha), and I used the same KDZ and instead of upgrade as the guide instructed, I used refurbish and that did it . In less than 1 minute it was up and running again!

As you can see i`m on 90% left,after 40 mins SOT.

Model: H815 ROM(Romania-Unlocked).
[G4 General] rav101:
If you are saying 5 hours after running a full cycle then awesome. I couldn't get that no matter what i tried and will much lighter use of my phone.

If however you are estimating based on the first 10 percent then i would advise you not to. The way the LG phones are set up, they take ages to drop down to 99 percent then speeds up after that. For example I can get over an hour on the first 10 percent but not over 10 hours of sot.
[G4 General] odarellmc:
Exactly
[G4 General] Alecs_Tm:
No! I'm not saying that i can reach 10H SOT. I know that after 80% battery is getting drained more fast,i'm just saying that i can reach about 5H SOT and i'm very pleased with that. :)

I have to mention that the phone is just 10 days old. And maybe that's one of the reasons i can reach 5H

The battery is "young" :)

You ask me, battery life is a PURE DESASTER! I barely get to 3 hours of SoT, I have Greenify installed, I set screen brightness to roughly 30%, I have GPS off all day. It´s a desaster. As much as I love this phone for it´s features, I´d never get one again. LG has to improve here A LOT or my next phone is gonna be from a different manufacturer.
