Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the LG V20's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

Compared to the Note 7 there is next to zero residual battery drain. I forgot to plug it in one night and saw a 2% drop.

Doesnt really drain on sleep mode. Not bad.

This is great to hear. My V10 can drop 30% overnight. I can't wait to upgrade.

I'm losing upwards of 15% at night. Not good.

This has been one of my BEST PERFORMED sleep time phone so far! Must be something w NOUGAT also? Love it!

I noticed sometime when we insert a new sd card the phone needs to create an internal list and this process can suck alot of battery. It might or might not be this issue thats causing some users to experience overnight battery loss.

I got my V20 yesterday and had it sit overnight, and the drain was practically zero. Very impressed so far.

Standby drain is beyond great. If the phone is off, then 0 to 1% is lost, depending on the stand by time.

The standby drain is unbelievable. I've noticed between 1-2% drain per hour. That's with bluetooth, wifi, and location on, as well as android wear and google fit constantly running in the background.
It's WAY better than my GS7 Edge.

So over an 8hr night you would lose 16%? That's not gifs at all.

I just got the phone last night. First of all... damn this is a sexy beautiful phone. Sleek slim as hell and the best phone I've owned thus far.
What is not okay is the battery drain in standby. I put it on the nightstand at 100% at 11:30pm, woke up at 6:30pm (7hours total) and it was down to 40%!!!!
Not okay LG. I moved over from the LG G5 and the standby on that was excellent, would still be in the 90%s , I hope an update is issued to fix this problem

Over 6 hours of stand by time with 0% lost. I have 4 email accounts running, a few game notifications, etc... No facebook.
This was taken after I cleared most of my notifications.

Give it a day or two, the battery will and should improve.

I too have noticed that this phone has significantly less standby drain than the S7 i was using between the Note7 return and the V20. All in all just better with the battery in my opinion. I usually listen to Pandora all day long at work (wired) and then use my BT headphones at the gym for a couple hours each night too. With the S7 I had to recharge the phone near the end of the work day or i would be cutting it close by the end of my workout. Not the case at all with the V20, after my workout im around 45% still. I do have 2 email accounts / FB / bunch of other stuff running at all times too pretty much. Get a lot of calls / texts throughout the day of course too. So far it has been amazing

I Have the V20 for 2 days and last nite lost about 30%, will check today what was running... not good but could be the battery ....

Sleep mode is awesome I bearly notice a drian.

7 hours I slept last night with v20 unplugged after fully charging. Burned 1%.
Your issue seems to either be low signal strength or apps waking the phone.

I am havei very little sleep drain. This phone has really surprised me. I have been loyal too thenote series since the n2.... And when the n7 issue started and we had to return it I decided to give the v20 a shot. So far it has really surprised me!

P585 here. Standby drain is fantastic. I charged it to 100% and forgot about it for a week. Found it on 97%.

SM-T550 and Marshmallow 6.0 the time with screen off and battery drain are great, 4 days 4 hours on standby starting at 100% and it is now 93% I had 7.1.1 Nougat on the tablet for a week and My standby time and basic battery use was 1/2 of what it is with 6.0 Marshmallow.

Didn't understand. Are you saying that with Nougat battery life was worse than with Marshmallow, or better?

Ok, thanks. I plan on getting this unit over the next week (Amazon has it for $178 right now), and like to know what t do or avoid. Conclusion would seem to be: stick to Marshmallow then. Not a problem,
Thanks.

I don't know which Nougat ROM you were using, but I have the Ultralean version installed on my T580. I just pulled it out of the shoulder bag where it is has on standby for the last 23hrs. It is still at 100%. Battery drain isn't just dependent on the ROM itself but also on what apps you have running in the background. That's why I chose a ROM who's main emphasis was on getting rid of most of the Samsung bloat.

He's saying it was much worse. But before abandoning Nougat, you might want to read this thread:

Almost everyone in that thread you showed me say the OP's solution does not work. Is there any compelling reason to install Nougat?

Are you sure you read the same thread that I did? Yeah, I saw that a couple of people didn't succeed in properly implementing the solution, but the majority did. Personally, I'd at least make the attempt to get the latest version I could to work, and then, and only then, revert to an older version if I couldn't. My standby drain is less than the bobfrantic reports with MM, so I know it can be done.

40 days and counting... I turn on the screen only to update apps.
Bought it second hand with faulty LCD screen, replaced it and now testing the original battery.

Normal is relative. Is it a bit on the low side? Most definitely. Normal? Maybe. It really comes down to the apps you have and how you use your phone. I personally get about 5hrs SOT and I'm fine with that. Standby drain is more important to me than SOT. There are battery saving tips and trick you can try to google or youtube.

My phone drains like 3% per hour on IDLE. I don't have AoD nor anything in particular that should be causing this drain. I have no idea why. The battery life seems to be fine for actual usage, but teeeerrible for AOD.

3% per hour no AOD is bad. You have an app causing major drain for sure. You might have to deep dive in your battery stats to find the culprit. Last resort would be safe mode to see if your able to reproduce the issue. You should go to the battery life thread and ask around.

I'm not sure what it could possibly be since my old Note 8 did this too, but it alternated every other cycle or so where it would drain less than 1% or 3%+. I exchanged it for a new one and this issue is happening again except it was completely fine for the first week or two. There was no app that I downloaded between the time that it was fine and not fine.
I guess I'll repost this in the battery thread.

i am not losing battery overnight as much as you guys, my problem now is i can't get 6-7hrs of sot anymore, 4-5 is as much as i get, and it's only 1 month old.

There was a thread about Android OS drain.

I miss my note 4. I use to get around 5-8 sot. With this phone only 3 and half hours. That's with everything turned off too. On my note 4 I had just about everything turned on. Will be waiting for the note 10 to release then I will buy the note 9

Best Kernel & Rom combo for a Grandpa (aka best battery life, minimal features)

I'm going to give this phone to my grandpa, he's used to a flip phone, so 3++ days battery life and such.
He will be using it to call, send sms and GPS mostly.
What is the most stable and least battery draining kernel and rom available?
I was using AICP 12.1 ( 7.1.2) with stock kernel
This is my current battery life, it just dies at around 50%

This seems like pretty good battery life on LG L90. I am still on my first stock rom (Kit Kat 4.4) , and battery life is bad. Even if not using phone, because I have a new one, battery drains by itself pretty much. If I use phone for internet surfing , it dies after maybe 3-4 hours of surfing.
Can you tell which ROM are you using?
I also want to change ROM and put some light OS with minimum features just to make phone lighter, more reponsable and to get better battery life.
I thought SLIM Os is the best out there for that.
Could you suggest better one ?

In my opinion Lineageos is better. Also im pretty sure its called slimrom not slimos but I have seen people that moved from slimrom to lineageos and said that the battery life on lineageos was better.

Using the pico or nano gapps also helps a little as they use less ram and CPU processes.(I use mini but I disable a few things). I get about a day an half when I'm using it constantly. Also make sure you don't install to many apps that run in the background and never use apps that free up ram ect as they are useless battery hogs. If you want free ram disable unused things.

Hi, i use a slimrom 7.1.2 without any custom kernel, and the battery life is very good and very fast also, i have hebf optimizer to tweak some phone parameters, and basicly i have everything tuned to performance mode, and with mixed use i have between 5 and half to 6 hours of screen on time

Whatever old rom u use, the battery drains come from Google play service and store, they auto update and u cant control this, the only way is freezing them and u will see the difference.
The best way to force people to buy new phone is overloading old ones without people realize that, the only ROMs with good Google services are the lastest.

NEW Thread, Battery Life (SOT) for Note 8 on Android Oreo!!!!!!

Post your most recent batter life number if you have a note 8 on the new android oreo update, lets compare and see how we can maximize use

Again, really? Just use it and recharge when required...

I'm bot usually that guy, but I tend to agree with this guy. Do we really need to obsess over how long we can use the device before the battery dies?
I've found that just using the device without caring how long it lasts, I get way longer than expected battery life.

The problem with this is, everyone uses their phone differently. So unless people will tell us how bright the screen was, using wifi, 4g, gaming, Facebook and for how long, etc etc, it would be pointless IMO. If you want better battery life, reduce brightness, as this is the biggest drain on the battery, stop all syncing, remove apps like Facebook, reduce the resolution, turn on power saving and turn off animations or put them to .5.

Exactly & agree on all the above. SOT is so over rated & it's easily to manipulate the results. I mean I have posted my SOTs before but I use it only for comparison, ie rom & kernel testing based on my own phone usage. Comparing SOT with others' results doesn't really mean anything except to those looking for some kind of useless bragging rights.

I find the Oreo update sucks. I dont know if its just me. my phones gets heated for no reason, even if its not being used or charging. Battery Life sucks so downgraded the Noughat. Happy to have the 5-7hours SOT and less heated phone.

Whats with these guys and the excessive use of exclamation marks? AND not reading before posting? There are several threads about this topic

sorry, I know some of you are just enjoy the phone etc, Im trying to find out what other people are getting as I seem to be draining pretty bad, when I use better battery stats it shows wifi running 100% despite it being off

Battery life dropped a lot with the Oreo update for me, har resetting, cache resetting nothing is helping. I get tops 3 and a half hours.

Yeah Oreo sucks I got only 3.5 hours SOT now back on Nougat I'm getting again 5-7 hours SOT

Didnt want to open a new thread for another Battery consultation. I have the 950U1 model and after upgrading to Oreo ive had an average of 1 hour and 15 min of Screen time and it drained my battery %6. Is that within the norms of how it is? Just curious.

Anyway, this is very strange as the majority is having possitive feedback on battery life, also the Oreo itself is having some battery (app) optimizations that should help... but no!

I started other thread asking for opinions about the OTA oreo, I mean only OTA, as some got their oreo in beta or cross flashing from other countries, or changing some parts, In my country we dont have OTA oreo yet, at least for officially distribuited devices which are ALL branded, (locked or unlocked), as samsung does not sell cellphones to consumers directly in Mexico, only through 3 carriers,but all these comments make doubt about updating from nougat, reading this thread has made my uncertainty bigger, in the meantime, I disabled OTA updates, just in case, maybe waiting for Oreo 8.1 would be better

You can't accurately judge/assess battery life in increments. Go through a few full cycles and see what averages out.

A complete disaster. That Dip is 45 minutes paying music with the screen off.
I've had it for two weeks, cleared cache and dalvik all that. I need know how to downgrade.
Google has been iffy. I have the unlocked Samsung note 8, I use it on Verizon. Bought it directly from Sammy
