[q] Sudden battery drain screen off - Galaxy S6 Q&A, Help & Troubleshooting

In the screenshot you can see from 12:00 till 13:00 I wasn't using my phone and got a 20% battery drop, I went from the office to home. Could anyone clarify this? See screenshot.

What does the app sucker in GSam say is using your battery?

[Q] Why is the battery percentage so inconsistent?

Does anybody know why is the battery percentage so inconsistent?
I am just switched over to the sensation from the HD2. I have had the phone for about a week now. The first couple of nights I turned off my phone because it was around 20% battery life. The next morning when I turned on my phone the battery percentage was at 33%. I have done a couple of other times and the percentage goes up about 10% after a day of use. My wife's sensation does this also. I am using the stock battery, and I am not using any roms or mods. I am monitoring with battery monitor widget and current widget to make sure it is not the app.
Anyone else notice this?
battery monitor widget is not anything official from HTC.
I think that is your problem.
I have never seen my % go from 20% to 30% without charging it.
I thought about that also, but I will turn the phone off with the battery icon at the top yellow color, and then in the morning it will be green. So the widgets would have no effect on that. Like I said I have noticed this on both phones.
I have also had my batter meter go up after a reboot. Not sure why... The meter works good enough to give me an estimate or battery life. Good enough for me.

I am not worried about it, but is kind of interesting how power cycling shows the correct battery. It must be some kind of glitch in the OS or something.
yeah, it happens to me too! For example, after a full charge the % stays on 100% for about 8-9 hours and after that it starts to decrease. About the % growing, it happened to me two times... maybe it's about calibration...

Battery draining while screen is off

Hello Xda community!
I'm not sure why, but recently my phone seems to be draining battery life quite quickly over night.
The really weird thing is this time, my phone was on the charger.
I put my phone on the charger before I went to bed last night, and the battery was at 65%.
When I got up the next morning, my phone was off for some reason, and I find that I only have 3% battery left.
Not sure if my battery is lying to me, but I have been running off the supposed "3%" battery life for a good 30 minutes now.
Either my battery is glitched or something else.
Any feedback is appreciated.

have you rebooted or done a battery pull yet?

First, use zeppelinrox's Die Hard Battery Calibrator, and then after you finish the steps it gives you an option to view what is taking up battery life, uninstall any apps that cause wake locks. Also, you're going to want to freeze the default android gallery and get a 3rd party Gallery (I recommend quickpic.) As the 3D gallery can cause huge battery drain.

Battery reduces 20% in standby overnight, is this normal?

My phone was reduced from 100 to 82 in just around 6 hours. I had data/wifi turned off as well. Is anyone else experiencing this?

Nope. With data/wifi turned on (data auto-off since Wifi is active), I lose at most 2% overnight. With airplane mode on OR data/wifi off, you should be seeing practically 0% loss.
Check your battery usage and see what's eating up the battery. Sounds like an rogue app/process that's wasting cycles or is out of control.
One of the best things about this phone is its standby life, as it seems to sip battery juice very lightly.
My battery was still 100% after I woke up today.
Nevertheless it dropped very quickly after using the phone, about 11% in 10-15 min but I assume that's completely normal after 8 hours standby.
I have a live wallpaper but it shouldn't work when is screen off. I also have setcpu set so that is practically doing nothing when the screen is off. The live wallpaper cost only 2% of my battery but standby showed 20%. I have no idea why it uses much in standby...

That means that of the whatever % battery (out of 100%) that you've used, 20% of that drain was due to standby. That's not necessarily bad. So if you have 50% charge left, then it means that (50% x .2)% of your drain was from standby. My cell standby has currently used 23% of my current drain percentage. Since your phone is often left in the sleep/not-active state, then a large % of battery drain happens in standby.
Battery usage on Android is frequently misunderstood. And keep in mind that the 2% from the LWP you used is because it's only displayed when you're on the home screen. Otherwise, it remains dormant/paused.
that's strange that you are having that much usage in standby.. i have been getting a solid day and a half out of my battery and it doesnt really use any battery in standby.. there has to be an app of some sort that is sucking the battery or still running.. i always at bedtime though clear the cache thru storage in the settings menu and end all tasks in the task manager and close all the windows/programs with the far right virtual button on the bottom of the screen.. I am a bit OCD but heck if its working why stop..lol
Area with poor cell reception? If you were in plane mode it is an app for sure.

My battery stayed the same overnight. That is with a x2 battery saver which switches off data when the phone is not used and only allows it as special intervals. I have set at 10mins intervals though which is not a huge saver.
I'm doing a test from yesterday to see how long the phone will last with my use. So far from last night im at 39% and when I first turned the phone on it was at 47% from yesterday.

I would have to agree with everyone else. I only experience 1% loss at most times overnight. Best standby battery life i've ever gotten on a HTC phone.
I actually have full bars at home so I don't think that's why. Maybe it's because it's a new battery so I'll try charging it a couple more cycles.
Lost 8% tonight (86/78). Saw this morning that the signal was not perfect. But wifi went off during the night. That should not happen. Maybe my custom rom is switching off wifi on sleep...

It's either a faulty battery or a rogue app. Shouldn't happen to a new battery either.

Use better battery stats to diagnose rogue apps.

Right.
Battery lasted up to 2:30pm being off the plug from 7 am the previous morning. So a total of 31hours.
That is with tapatalk, a bit of web browsing, a bit of WiFi and google store updating, 2 short phone calls.
The app. 2x was running on mild battery saving,mainly by cutting the data periodically when the phone is idling.
I must say that this is really good and the phone took quite a while to go from 15% to 4% after which it switched off before I noticed it again.

Inconsistent Battery Life

I'm on cleanrom 6 and I noticed a huge difference in battery life between today and yesterday. Yesterday I went from 5am to 11pm with 40% still left. Today I've gone 5am to 8am with only 75% left. Is this possibly a jellybean issue or a Rom issue?

Sounds to me like your battery life doubled

When I was on stock ics I could easily go 24 hours or more between charges. So I'm more surprised by the drain this morning than the lack of drain yesterday.

Some times battery needs to settle with new Rom. Download gsam battery monitor , battery needs about 5 days
Sent from my HTC One X using xda premium
Eh, or give it 1 charge cycle to stableize. (let the battery drain the first day, charge overnight and I'm usually good.)
But yeah, as said above download Gsam battery monitor to see what causes your drain problems (whether that be your screen or an app). Chances are that it's Google maps.

I'd give it at least 2 or 3 cycles for the battery meter to calibrate properly. But yes, if the ROM was just flashed, the initial battery readings are not to be trusted.

Were you using the phone during this time period, and/or in the car?
I can get typically round 48 hours on a charge, with low usage. But the other day it drained 30% in a half hour because my kid was watching YouTube while we were driving (through a somewhat rural and possibly low reception area).

The reason why it don't show i unplugged phone around 2:30 am after that i went right back to bed and just woke up now , so thats normal will not show apps since phone wasn't touched till i got up, once you start using phone and apps then it will start showing apps being used!

My battery drain overnight is minimal, 8 hours off the plug on a full charge is 4-6 per cent.

So before you stop using phone for night do you close all apps in background for them not to show or just leave it?thanks for info
I'm having a battery issue as well. I had my phone on the car charger for 5 hours and it showed that it was charging but my phone dropped to 6%. There were no apps running in the background and I restarted the phone.
My T-Mobile variant S8+ seldom has more than a 4% drop after being fully charged and sitting on desk for 8-9 hours. I've disabled Bixby and several other services.

I've had a couple of instances when the battery would not charge when plugged is. Showd as quick charging, but no increase in percent battery charge. Rebooting fixed it for me both times.
Sent telepathically
I usually charge my phones overnight, but in the one instance that I left it unplugged, I was pleasantly surprised to wake up to 100%. Not a single percent dropped. It's worth mentioning that I turned the phone over so that AOD would shut off.
i've been having issues as well. it has been draining 20-40% overnight lately. i got gsam with advanced stats on and have been removing stuff... i'm not quite sure what the culprit is, but i think it might be dt ignite so i disabled that.

You need to identify the what the wake-locks are that are causing the battery drain. Install BetterBatteryStats, charge your phone right before bedtime, then leave it overnight to collect data. Post a screenshot of BetterBatteryStats when you wakeup the next morning.
i have the same problem with my galaxy S8 i lose overnight between 10 and 20 %.. before this problem i lost 1 to 3% overnight and now it has been a week that i have this problem of loosing 10 to 20% :/
I have my Wi-Fi off, phone face down so Aod is turned off. Location is on power saving mode. Optimised settings ,fhd+. Still I lose more than 10% overnight. What should I do to reduce this drain ?? I am getting a great battery life otherwise on my note 8. About 6 to 7hrs of Sot with about 18 hrs total.
I`m getting 2% drain over 8 hours of sleep with AOD off , wifi on or off it`s the same 2%, location always on on power saving mode.
