Mysterious draining of battery on my One S

My One S with no phone call or surfing the whole day and now its down to 20% since happening the last 2 days.
I have not reboot my phone and I go to Battery Use to take a look and it say this today:
Screen 85%
Android System 5%
Androis OS 5%
Wi-Fi 2%
Cell standby 2%
How to troubleshoot this?
Thanks!

Ya reboot your phone theres a bug somewhere and it likes to drain the battery fast.

I did reboot yesterday cause it was totally drained. I am going to reboot again and fully charged and see what happened tomorrow evening.
I thought the "Battery Use" thing would tell me lots of thing and it did not.

Ya soon has you see it draining you want to reboot, no app will tell you its just a random thing and can drain it really fast.

You call this mysterious...? Mine had a drain even when my Phone was powered off But after reboot, removed some apps, all is fine now and my battery is doing great.

As in it drain like if you had it on and had this bug?

At that time, my phone was draining very fast, during the night (flight mode), lost 20-30% and when powered off for some hours (5-5 hours) it lost about 15%. Now when in flight mode during the night, i loose max 1 %

Hmm ok that don't sound right, that really is one messed up bug.

Before I install Vonage and Viber, everything was OK.
I uninstall Vonage and it still drain.
Now I put Viber back and see if it drain. I will reply back tomorrow.
Anyone have this problem with this 2 app? I need a VOIP that doesnt drain the battery.

I have viber installed, no problem with it.

[Q] Cell Standby Battery drain

Hey,
i just had the feeling that theres something wrong with my battery stats. Cell Standby drains about 25% battery up to 50% sometimes.
Is there something wrong with my nexus 5?

well it looks like you were in an area of no service for quite a while (the red bars). The battery gets crushed when there is no service and it is searching for service. I would put your phone in airplane mode if you know you have no service in an area. For example, when I enter the subway I put it into airplane mode to save battery.

I always recommend DS Battery Saver on the Play Store. When your screen is off, it turns off data (3g/4g).
To give you an idea of the benefits, I've been at work for 8 hours now, used my phone heavily at lunch, and my battery is still at 84%.

well, i tried using noBars or Autopilot but both arent working with 4.4. Instead of enabling flightmode they just crash..
So besides teh cell standby the battery stats seem ok? i was just wondering if there might be something wrong with the actual battery hardware.

Accurate battery life?

Just got a new Z3 D6616. This is the battery life projection I'm getting. I bought this phone because I heard great things about it's battery life. Also, when I saw a YouTube review, the guy's phone had a battery life projection of several days. Is something faulty with this specific handset? Am I doing something terribly wrong? Please advise.
PS. I'm at about 30-40% screen brightness with the adaptive setting on.

You should actually use the phone from 100% doing your daily stuff till about 1% and take screen of your on screen time. On screen time is what matter. They claimed to have at least 8 hours SoT with normal usage but the max I can get is only 4.5 or 5 hours.

I did a lot of reading before buying the phone. Heard about the "memory" screen or something that helps towards battery life. Several users claimed 10 hours SOT. Could it be the newer firmware that might have reduced it? I'll post the YouTube videos I saw shortly.

I use brightness at about 1/3 and have location and autosync on. I get about 8-9 Hrs SOT in a 36Hrs period.
At first even I got 4-6 Hrs SOT until it calibrated over a few charge/discharge cycles.
It takes a few cycles for the battery to calibrate, if you want to do that faster do the following:
1. Drain to 0-1% with normal use
2. Do a full charge till 100%
3. Do another full discharge (Dont charge in between)
4. Do another full charge till 100%
5. Now just use it how you want.

Thanks! Guess I'll have to report back report back after a couple cycles.

I have the same problem, I have enable the stamina mode, have the brightness at half and auto,and the battery won't last for one day,as an example today when I get up after I unplug the device it go from 100% to 99% right away and now after 10 hours without game,photos just Internet reading over WiFi the battery is at 31%. It doesn't seem normal, what should I do?must go to service?

I'm at 59% and my phone predicts 1 day remaining.
D6616 as well
I do suspect an app draining my battery though...

Nope, 1 day 19 hours standby
Well, it says 23 hours now... and 1 day 18 hours in Standby mode.
I also have no power saving features enabled, with max brightness..
I can get 6+ hours if I limit my brightness, but I settle for less with max brightness throughout the day.

Could it have something to do with the display image enhancement mode? I'm using X-reality. What about you?

I have it turned off, I can't really tell a difference..
Sometimes my "battery forecast" is low like yours though, I wouldn't worry about it unless you're actually getting bad battery life.

The battery life I'm experiencing is worse than the "forecast", which is essentially what worries me. Regardless, I've no right to whine unless I've cycled the battery completely at least once since it is after all a brand spanking new phone.

I doubt I'd get the 24 hours from now with my current use either. As long as it lasts me throughout the day I'm fine.
I can generally go the entire weekend without charging my phone though.

Ive gone through 3 Z4s (Cosmetic defects/lightbleed) on my 4th Z4, all of the were bad until they were calibrated within a few days.

I think you mean Z3s...

Lol yes.

I fully discharged and recharged my phone. Now I got 18 hours usage, including 7 hours SOT with the screen on max brightness for half an hour. It's getting much better now, certainly a huge improvement over my previous phone!
Sent from the inner sanctum of my mind.

That's more like it, it should get a little better.

Please have a look towards the end... My phone's been awake when I was asleep. Is there an issue with this phone deep sleeping? While I get a good SOT, the idle drain is too high! Please advise on how I could investigate if a particular app is doing this. I used to use "wakelock detector" but that no longer works without root.
EDIT: Stamina Mode always on.

I have the same problem too... Whenever I leave the phone idle, even with the stamina mode on, it still uses the battery as if I was using it.

The battery drain is minimal with AOD on but I use the option where the AOD only shows when I pick up the phone

Hi ramheer
Do you agree with devsk assessment of the AOD that the battery drains at approximately 2% per hour with it on?
Not sure if he has it always on or just motion like yourself...

Thanks for the reply
I've just started to use the phone after all the set up and transferring sim over and I started with 100/99% before bed and it drained 10%.
Maybe I need to let the battery settle and try without the AOD tonight as a test.

Every AOD implementation drains ~1% battery per hour, but the problem here is that this device has LCD screen, which increases the drain.
I have a device with AMOLED screen and I get around 7%-8% battery drain overnight with AOD enabled, so I just decided to disabled it most of the time and just enable it at certain hours.
I saw the U11+ has an option for motion, so maybe you should try that.
:good:

I'm already using motion but I've not used my phone as my daily driver until I had it just right and today is the first full day. Might be teething problems

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 Samsung Galaxy M30s'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!

I dont see any standby drain. When I keep data on (locaion,wifi and bluetooth off) in the night it drained only 2-3 % battery. with data off/location/wifi/bluetooth off it was 100% in the morning.
But I have a different issue, When I am using the phone, I see a drain now which was not there initially. Android system is draining most of the power. I usually used to get 9+ hrs SOT with 2 days usage. but now Both have dropped below to 1&1/2 day and around 8 hours SOT.. Tried all the things found on net, but it didnt helped.

Same things happens with after update. Before the update it works for 2 days but now a it runs for 1 & half day max.

I did the update too, so you think it caused by update? Is samsung deliberately doing it as everyone suspects of them doing that they slow down the devices or its just a bug they didn't realize?

Maybe it's a bug.
All tests are under airplane mode, no cell signal.
WIFI ON with "battery saver" OFF takes 0.5% per hour drain.
WIFI OFF with "battery saver" ON takes <0.1% per hour drain.
BUT !!!
WIFI ON and "battery saver" ON at the same time, the standby drain will up to 1.3~2% per hour.
I have test this for more than 10 times, trying to avoid any other cause.
Finally I'm sure that "battery saver" mode will cost more standby drain if WIFI is ON. （ yeah, that sounds ridiculous
But I don't know why.

Today night 8 hours : airplane mode, communication OFF drain=0% ( jawdrop).

What do you mean by battery saver ? How can i turn it OFF?

You can find it in quick panel or an app called "Smart maneger".
If you didn't turn it on , it's off defaultly .
Maybe your problem has nothing to do with this.

:laugh::laugh::laugh: What you expected ? Let me explain that smartphone is a little computer with operating system - which is essential to it's existence and work.
If you do not want Android to consume energy then you should power off the phone :laugh:
11% is pretty normal

Losing battery when phone is idle, overnight drains about 15-18%%

The battery performs well when in use (discharges at the rate of 10% per hour Heavy Gaming 'CoD: mobile', which is quite good I guess) but when the phone is idle, the battery drains quite fast about 2% per hour and the battery discharges about 10-15% over the night.
Losing 10-15% battery is not normal for a phone at all, also 10% of a 6000mAh battery is quite huge.
This problem persists. Any help is welcome!
EDIT :
I have uploaded the battery usage stats screenshots on google drive, check the link. I turn off WiFi and clear recent apps before going to bed but still, the battery drains heavily 15% over 6-7 hours.
CAN'T share the link because xda won't allow posting URLs here as I'm new to XDA forum

How did you figure out the root cause? I am also facing battery drain by Android system after the recent security update.
