[Q] battery drain while switched off

I noticed this a couple of days ago: I was in a place with no 3g nor wifi so I decided to switch O7 off. In the evening I switched it on and battery was empty.
I tried again yesterday with the same results. What"s using this phone while it's off?

Are you sure it is actually flat?
My battery has a problem, if i turn the phone off and then on it will show that my battery is empty and want to turn on battery saver. If i keep turning it off and on and mess with the battery contacts it reads properly.
Just a thought....

This is because the battery is cold, let it warm up and it will display the correct level

This happens after being on for days, it's not to do with temperature.

It also happens to me. Not usually but once every 1/2 weeks. I've been looking for a solution and the only one i found is switching off and on again until the battery level is ok. However i have to say that this has been happening since i installed 7740 update, so maybe the problem is that.

not actually drains...
I think the battery did not darain.
It is just the battery level is not displayed correctly; I had the same (or similar) problem. I switched off the phone while the battery was at 80% and the next morning when I switched it on I got the message "the battery is low..." and the wrong battery level displayed.
I kept it on for hours and it worked nicely; I noticed the battery info displayed 1% of residual charge and 7 hours of expected workng time...something weird
Suddenly after hours of usage the battery icon started to work properly.

Exactly the same as me. I'm on my 2nd Omnia handset now (warranty replacement) and this one does the same so I assume it's the battery that's faulty.
If you leave it on long enough the battery meter slowly increases over time until it reaches the true value.

Just installed 8107 upgrade via cab; let's see if problem have been noticed before and solved now

I noticed this problem also. After the mangu upgrade it is not there any more.
For me it seems that th eproblem laid in the firmware..

funny, I'm not the unique
Today I've tried to make an hard reset to see if the problem would have been solved. I'm on Mango 7740, tonight I'll try to switch off the mobile phone after charging.

I did a hard reset, OS update and then a handset replacement and the problem is still there.
I'm convinced it's a fault with the actual battery.

Ok, I yesterday evening I switched of the smartphone for some hours... Then I turned it on and I saw the"popup" which told me the battery was low.
I left the device on, with 3g on for all the night and this morning I found the battery level as it was before yesterday evening
I confirm the battery do not drains when the smartphone is turned off!

As I already said, this is because the battery gets cold when you switch off your phone, and it then appear drained. After heating up again it will recover it's charge.

Note 3 Exynos - Battery dying even on standby

I bought my Note 3 in December from a Samsung Smart Cafe. The phone was amazing throughout the last few months. 2 days on medium usage, amazing WiFi connectivity, awesome gaming experience.
However, 3 nights back I had left the phone (at 50% battery) and gone to bed around 23.00 hours. The next morning I woke up late at exactly 10.00 hrs. When I went to check for any missed calls I found that the battery had completely drained off and the phone was dead. I turned it back on t see that the battery percentage was 1%.
I want to clear out that the following are deactivated on my phone:
1) S-Voice
2) Wake up in lock Screen
When I checked the battery stats I found that the screen was using 56% of the battery. How could that possible be when the screen was switched off the whole time.
Since then every night there has been a drain of about 46% every night. Earlier it used to be only 2-3%.
Could you guys please help me out here? Really tensed
P.S: Last night I left the phone on flight mode and went to sleep. The battery drain was only 1%.

Guys! It happened last night again. This time around, the battery drop-out was around 40%.
Please help me out on this. Any kind of suggestion would be awesome.

Install app called gsam from Google play, one of your app may not allowing your phone to go on deep sleep. If you have installed any app recently try to uninstall.

Hey, the most recent apps that I had installed before the battery went bonkers were:
1) Truecaller
2) BosonX
3) Freeze
I uninstalled all of the three apps.
I have installed GSam battery monitor and the main stat that is abnormal according to me is that the battery discharges 43% even when the screen is off. I have a radio signal usage of about 42% which I think is pretty normal and I do not have bad reception.
Still, last night the battery went down to 80% from a full charged state of 100.

Let Gsam to monitor for two or three more complete charge & discharge cycle so u may come to know where is the problem, some time ext sd card also causing battery drain problem, if u have than try to use phone without sd card for couple of days.

Battery issues

Dear XDA,
Since a few weeks I began experiencing problems with the battery of my Galaxy Note 4 (SM-N910F).
It all started with the phone lasting a lot shorter per day and suddenly shutting off at around 5-8% battery left.
Today it was the worst I've ever experienced. I make a short list of what happened.
Charged to 100% overnight and taken charger out at 7:30
Went to the gym, 98% left after 1 hour idle
Bumped an extra 4% when transferring files from PC at 15:10 (from around 78 to 82%)
Watched 10 minutes of Under the Dome and did some Whatsapp
Read an article on the internet
Phone was suddenly at 28% at 19:00, shut it down for a bit
Powered on at 19:25 with only 18% left
Phone died at 19:30 with 14% left. 2h and 40 min Screen On Time. 12 hour standby.
Still able to boot but can't get past coloured Samsung logo
LED Notification stays blue and can keep booting for about 30 more times.
So basically my phone died after 2h and 40 min Screen On Time with still some charge left.
This is the worst I've had so far.
The weirdest part is that the Notification LED stays on after trying to boot it once. The only way to remove this is by taking out the battery.
When the phone was new I was able to at least get 4-5 hours Screen On Time depending on brightness.
Things I tried to solve it:
Full charge cycle and emptying it
Factory reset
Checking for unusual activity (wakelocks)
I've checked for any wakelocks but I think this might be a defect instead.
Can anyone please help me? Any advice is appreciated! Thanks in advance anyway!
Kind regards,
Daniel Collignon

Anyone?!

Try a new battery, it can become 'weak' after a while.

Don't worry ! I have gone through this too . A log or a screenshot of BBS , System battery graph would help us . Please share it

well my phone is n910H. it lasts less than a day and it dies when it reach 30% and when i connect the charger it gives me 0%. does this means the battery is faulty or is it a software issue ?

Me too!
I have the exact problem stated in the op. I am pretty sure it must be a callibration issue because I've tried too many times the *#0228#. I've tried taking out the battery and putting it after some minutes. I've tried off-charging, on with screen off charging, on charging, fast charging, slow charging, everything and I have at most 4 hours of use, with 1 or 2SOT.
Sometimes I charge it and it stops at 70 or 75%. Today, it stopped at %50 (off-charged) and I removed the battery, waited 5 minutes, put it back on and it showed 100% (still off). Battery lasted less than 1 hour (okay, I was playing candy crush and clash of clans ).
I use my phone without the power saving mode for a snappier performance, but it's impossible that the battery lasts so little time.
Could you solve it? or just bought a new one?

Battery drain
I have same issue on my Note 4 for a last few months. And it's just getting worse.
Today it dropped from 48% to 5% and turned off.
I even took it to Samsung service and they told me that everything is OK with phone and that I have to change charging equpment.
I did that and it didn't help. It's happening again.
Help please?

Battery goes insane

We all know the battery was perfect with M, we all know that since N battery drains way faster, but I've gotten used to that.. Instead of 5 SOT I got 3.5. Ok.
But now.. I hardly go past 2. Battery drains really fast, it's not even stable. Doze doesn't seem to work anymore, percentage drops each minute and a half, and now.. phone shuts down at 6% all the time. What should I do?
I'm a stock user.

You could install GSAM and see if it's an app causing the issue. You can also try turning bluetooth off completely for a day or two to see if that's a cause.
Worse case, you can do a full factory image re-flash. In my past experiences, most of the time, updating OS major versions never sat to well with my phone. I personally do a full factory flash-all after every major update.

I have GSAM but since N it doesn't show stats for specific apps but only combined. As for Bluetooth, it's never on.

Well that narrows it a little more than.
Actually, with a recent update, you can see now.
If you go to Enable More Stats, it will give you directions. I believe you need a file explorer, move one file to another location, and rename that file.

Software fault. The battery doesn't really charge fully, I've noticed that when my phone froze (literally) and it was on on 50%. I warm it up, says 1%.
After that my battery life is exactly half, which means that 1% is actually my 50% but the phone sees it as empty.

Check battery capacity with accubattery. Not completely accurate but it does give you a ballpark range. If the current capacity is way less than the specified spec, then you have a degraded battery

I agree with the Accubattery approach (or similar app) to measure the battery capacity. Several ppl have experienced degraded batteries.

I've done a factory reset, Accubattery shows 3022 out of 3450 mAh and 88% of battery health. Do I need to replace the battery?

Not unless you can get Huawei or Google to do it for free. I haven't seen any new genuine oem replacement batteries. They are either used or fakes that don't work right. Some don't even have a temp sensor. Accubattery shows 2876mAh for me and I get 4.5 to 5 hours sot on 6.0.1. Same as I ever got. After installing 7.1.1 with full wipe from factory image, same settings, same apps, same signal, same usage, I get 3-3.5 sot. On nougat my phone would intermittent turn off under 15%. Hasn't happened once since I rolled back to marshmallow 2 weeks ago. Either some people (like me) are using certain apps that consume battery without it showing on gsam and better battery stats, or nougat just uses more battery when the screen is on. I believe the latter.

I wouldn't think so based on that snapshot. I'd keep running the capacity test (documentation states accuracy is improved with time) and start looking very closely at individual services and apps for anomalies. If rooting is an option for you, wakelock and battery statistic tools are better able to return more accurate data than non-root apps. Absent any rogue apps or services, monitoring the capacity will give you a trend and likely answer your question about replacing the battery.

Ok, good to know.
Can you please follow this order of events?
1. The battery was as I've noted at the beginning of the post, drains fast and shuts down at 6%
2. I've had a factory reset.
3. I turned on the phone, clean and wiped, at 35%. It took me 1:29 hours to get from 35% to 7% [which is great!] but then at 6% it shut down again.
4. I turned it on right after, it showed 1%. It lasted for another 10 minutes of usage.
5. I charged it to 100%.
6. Then, when the screen is off, battery loses 2% per hour, and when I use it, it loses 1% every 3-4 minutes [which is great], BUT - sometimes it loses 2% at a time, say 80 to 78 and so on. I still don't know if the phone is gonna shut down at 6% or if it was already fixed.
Does that seem normal?

It doesn't seem normal to me. Neither the 6% shut down nor the increased battery drain. As I said, I had both issues to some degree, early shutdown, and much less screen on time. Since a switch to 6.0.1 fixed both issues I am lead to believe they are software problems, not hardware. Google responded on reddit that they are looking into the early shutdown issue about 10 days ago. Then there is also the sudden influx of bootloops of death after Nougat. My advice is to use Marshmallow until things become more stable.

You could go into accounts-Google and see if there are any syncing errors.. Facebook and Facebook Messenger are both known to cause big battery drains on Nougat. Gas Buddy used to be a problem as well but not sure if it still is. As another person suggested doing a full flash-all.bat clean install might fix your problem. Some people just go back to Marshmallow,

Moto G4 battery dies extremely fast

Yesterday, my battery was running perfectly fine. Today, the battery goes for about 10 minutes on screen time. Getting it charged from 10% to 100% is very quick, maybe takes about 10 minutes. But going from 100%, it can discharge at about 5% per minute, regardless if im using it or not. When I was at 70%, i tried to restart my phone to see if it would fix it, but when It was going to turn back on, i was greeted with the low battery sign, signaling that the phone wasn't able to turn on. 70% = No Battery? Battery drains by 2% per minute when screen is off.
I'm running Lineage OS 14.1 official rom with magisk. Please help.

Many times i have watched my battery go down multiple percent in a matter of a second its really scary

Your phone needs to re calibrate the battery. This is probably the bit I like the least about these phones. Near as I can tell the best method is to let it drain till dead - then plug in with your charger and leave for several hours. Power on while phone is still plugged in - let it continue charging another hour.
Use normally. You may need to repeat this a few times.

I've done that about 4 times. It didn't really make a difference... then I used a battery callibration app from the play store which didn't even require a full battery drain or charge and it worked very well... weird.
