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

[Q] What is normal battery drain?

What is your normal battery drain when your phone is idle? I have an hour and 15 minute drive to work each day and my phone sits idle the entire time when I get to work I notice that my battery has drained about 3%. Is this normal or is this high?
I'm running teamhacksung build 16 with glitch beta 3, of course this has been the case for every ROM I have installed. Btw I keep wifi and gps off at all times and I'm syncing only gmail.
The reason I ask is that I was given an iphone for work and I couldn't believe the battery life, of course I could never leave android for apple...I just can't customize it...
Thanks in advance.
3 % a hour, that's high, im on kk4 based rom & kernel and my cappy drained average 1% per hour

Perhaps during your drive you are going through some areas of weak signal where the phone needs to work harder to stay connected.
You can look at Settings to see what has been using your battery during that hour and a half.
That's similar to the battery life I'm getting. I think I can get better drain if I don't overclock

^same. Its also the same if I'm running cm7. On THS ICS, at most I can get 2 and a half hours of screen time o.o

I have seen my phone idle between .5% to 3% based on strength and stability of signal, no other factors involved. Since traveling at vehicle speeds = less stability. It's probably the reason for your loss, you can try different modems to see if one talks to the towers better so hand-offs go smoother.

Here are a couple screen shots I took after my phone was sitting on the counter idle for a little over an hour.

Yeah I'd say that 3% in 15 minutes is high - I probably drop 1% to 2% per hour or so when idle (but I keep wifi and mobile data disabled when not in use).
Even when I'm work though where my cell signal is weaker I don't think I've ever seen my battery drop 3% in 15 minutes.

Google services draining ~70% of battery please help

Hello , I am experiencing drastic battery drain by Google services . I have tried disabling it (its Google bookmark sync service) but still it's draining the battery more than anything else

Where are you getting "drastic" battery drain?
You went through 48% of your battery in 7.5 hours. Thats not drastic. id consider that normal.
Also your numbers are way off.
You still have 52% battery remaining according to the screen shot.
So 76.4% usage OF 48% consumed is what is actually being represented there.
Remember that any time you look at your battery stats the calculations have to equal 100%.
So if you have 90% battery left. Then only 10% has been consumed. So of that 10% consumed its representing 100% of your apps that consumed 10% of your battery.
Now if you drain your battery to say 5% or less then you get a better representations of what is consuming your battery. But if its still going on 12+ hours your doing well.
From what i read on your screen shot your looking at around 14 hours of battery life.

I removed Google bookmark sync apk from system/app and now its 63% when I got back from school .. actually I leave for school around 7 am (phone is plugged overnight, I just unplug it and keep it my bag) use of mobile is prohibited in school so it's not even used for a second till 2 PM . Resting idle and having 48% battery drained . When I have extra classes after 2 PM I can use it and its dead by 7:30 or so in the evening .. I get 11-12 hours ...

Bad signals at school maybe?
Sent from my HTC One using XDA Premium 4 mobile app
I've heard of this problem from somewhere and from that someone suggested turning location services off in Google now or completely disabling Google now. Also an easy fix would be to put airplane mode on during school as long as you don't mind losing the possibility of someone getting in contact with you.

[Q] Is my battery life normal?

Hi,
I've had a Nexus 6 for some days now, and its battery life doesn't seem too good. I'm used to leave my phone overnight and wake up to it having over 90% battery left, but with the N6 it usually has a little over 80. Today it had 83%, and after browsing the web for some minutes (maybe 10 or 15) it's down to 75%... That's almost 1% a minute, which seems a lot to me.
If I take a look at the battery screen, I see this:

If I'm not mistaken, something seems to have kept the phone awake during the night. Is that right? I'm using M preview 2, could that be causing the problem? Is the phone defective? What could be wrong here?
Thanks in advance for your help.
PS. Battery life is at 71%... That's 4% down since I wrote that part above. This thing drains so fast it's scary.
It could be anything from the ROM itself to a Rouge app. I would flash back to bone stock and see what you get over a few days with a couple charge cycles. And then compare with another ROM.

Yes the andoird m preview 2 is not showing battery stats correctly. You will probably notice that once your phone goes down to 1% it could stay there for an hour or so. Just be sure to run the phone to complete 0%. Then charge to 100% and leave for about an hour after that. That should recalibrate it after a few cycles. It is a widespread "issue" with the m preview 2.

+1 to this. I use a lower voltage charger, not the turbo charger, and charge my N6 while I sleep. I have since day one with this beast. I've had it since November 20.

i use the turbo charger. but it doesnt matter. if you watch the voltage going in, it get drastically reduced above 92%, and again at like 97%. and when the device actually stops charging, its at 0% voltage going in. btw, most times it does not stop charging at 100%. that happens anywhere from 5 minutes to 30 minutes after hitting 100%. thats because our battery % is slightly off.

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.
Then, drop a comment if you have anything to add!
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.
Sent from my LG-H918 using Tapatalk
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.
Sent from my VS995 using Tapatalk
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.

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!

Is my phone battery dead?

I got my note 9 two months ago, I downloaded Accubattery today to check battery life then I charged it from 7% to 100%. I was shocked when saw that the battery capacity is reduced a lot! The app says it is now 3505mAh !!! With only TWO MONTHS OF USE !!!
Is that app accurate ?
I play PUBG a lot but that is why I bought the phone; because it is powerful and SUPPOSED to deal with that much of usage !!
I also use VPN all the time
I use 4G only no wifi no NFC no BT
When sleep for 6 hours with mobile data off .. standby consumption is about 2-3%/6 hours
Any suggestions ?

Read this topical about battery on Note9 and do not use any battery monitoring program. Erroneous readings.

Accubattery is your problem my friend, not your battery.
Enjoy your device, stop worrying that much about the battery.
Two hours of screen time presumably playing a video game most of that time, and still have 70% battery remaining. Iphone users would kill for that kind of battery life. Think about it, 2 hours of game playing gets you 30% battery drain, then I can surmise that you can play nonstop for around 6+ hours before your battery dies. That's excellent by any standard. I remember a time when 2 hours of screen time was considered decent, and that doesn't include playing a battery intensive gave. And that time was really only a few years ago.
It seems I'm over-concerned about the battery stuff.
Thank you all.
