Standby drain

[axylophon]

Yeah it is indeed really strange. This bug was not present in Lollipop. It occured first with Marshmallow I think.

It has something to do with the network configuration as you already said. Something with IPv6. Last year I googled that topic and found other people which have the same problem in the "EDUROAM" network at the university.

I hope it is working...
Everytime I did something with my phone I switched on the wifi. Afterwards i turned it off again. Otherwise it would be empty after around 6 hours.

Maybe Android O is fixing it.

We will see

And if you install something like the Doze app from play store and only whitelist specific apps? Would be interesting to see, I suggest this purely cos Doze creates a pseudo VPN, effectively blocking traffic that's not on the whitelist.

Does nothing, nor Force doze and nor the aggressive doze included with greenify.

Damn, weird, have you tried hard (button) reset yet?

I remember once having an issue with Greenify, have you tried uninstalling it for a day and see if anything changes? In my case Greenify got stuck in its own auto hibernation loop, which drained my battery heavily when phone was in idle mode, with aggressive doze option.

I'll try to uninstall greenify.
For the hard reset, it's the first thing i've tried, but probably this is an LG problem present in: G5, G6 and V20, came with Marshmallow and stayed with Nougat. Mind that with S8+ and S7 Edge i've never see a problem in standby

weird, cos I have no such issues, I easily get 6 hrs SoT and 2 to 3 days between charges...

I never reached more than 4 hours under wifi, with mobile network is even worst

4h 36m 18s SOT vs 30% juice

will clear 5h SOT for sure, not sure about 6h.

I don't extactly know what causes strange battery drain but with the same settings (AOD, WiFi & LTE on, many apps in background etc etc) I can reach different SOT values. More I use the phone and more SOT I get.

Just look at the attachments on this post.

So far battery drain on standby is almost non existent.

Hey guys! It's me again, and I bring word from Lord Elrond of Rivendell.

As you may have read a few posts ago, my phone's battery was being massacred by a wlan_rx_wake kernel wakelock while connected to my university's WiFi. I looked everywhere for a solution but none was to be found. I knew my good ol' Nexus 5 had had the problem fixed by having Franco's Kernel flashed into it, so I looked further into that. I had never ever considered building my own custom kernel, but sure enough I ended up porting the fixes from Franco's kernel to some sort of modded stock LG G6 kernel. I am pleased to inform you, ladies and gentleman, that the wlan_rx_wake wakelock is now nowhere to be found. I would (and eventually will) post the kernel in the Development section (I even made a neat flashable zip even though I had already flashed the kernel from a boot.img), but I am sadly not allowed to post there yet.

My success was very short lived though. I went from a phone that almost never slept while connected to my university's WiFi to a phone that did't sleep at all(!) while connected to said network. The new culprit was a partial wakelock by the name WifiOffDelayIfNotUsed. Again, I looked into this and I read that some people had fixed it in LG G4s by modding the system framework. And so I did, I modded the G6's framework and the WifiOffDelayIfNotUsed is now also nowhere to be found. Again, I went through the trouble of creating a neat flashable zip even though I had already pushed a patched .jar, I'll post it as soon as I'm allowed to.

I'd love to tell you guys that my phone sleeps deeply most of the time it's connected my university's WiFi, but such is not the case yet. Back at home the battery life is superb, but at work I still struggle to deep sleep while not in use. This is all very recent, so I guess there's a chance my mods haven't settled in yet (the patched .jar file does't appear to have been "reodexed" yet, I don't even know if that's a thing but I'll be sure to look into it). I still look at all of this as progress though.

That's pretty much it. If someone is in desperate need of either of these fixes I'm sure we can arrange something while I'm still not allowed to post them. Otherwise, I'll post them soon enough.

Cheers!

Hey Guys,

I've been experiencing some battery drain overnight when I go to sleep. I turn off wifi, bluetooth and data when sleeping.
Battery still drained 9% overnight.
Something within the Android OS is keeping the phone awake. Is there anyway to find out what exactly is doing it?

Here are some screenshots:

Cheers!

Using a 870DS with the latest software TWN V10e.

It is looking normal. Last hour drain is high but anything else ok. As you can see the remaining time stands by 44 hours.

I won't consider it as normal when you lose 9% overnight when you turn off all data. I'd say 1-3% should be normal.
I have enabled Wifi & data overnight. No special night mode just on silent. Loss only 1-2% overnight.. This phone (android general) has sure a weird habit for idle

 

[Kaleidosc0pe]

I think it shows you wrong stats than with 9% loose you can not get 66 hours left.

overnight drain is unpredictable for me. i've seen 5%, but usually it's 2% or 3%. but last night: 0% drain. woke up to 80%, which is how i left it, go figure.

I leave everything on during the night apart from AOD. So that's Bluetooth on (Connected to my Fitbit Blaze with all day sync), mobile data on, WiFi set to always on (I found that gave me better idle), I also have do not disturb active during the night.

I went asleep with 8% and woke up to 8%. Getting around 6h SOT in general

So I got my G6 EU yesterday and I'm bit disappointed as LG still didn't manage to increase battery time. I know that Google is the one to blame here for greedy apps like Play Services and an architectural design that does not prevent bad developed applications from wasting battery time...

But when I think of my Honor 8 - even with LOS battery is significantly better.

It would be awesome if you could link the page where you found the solution!
