sudden complete battery drain - Moto Z Play Questions & Answers

Hey folks, I've had my Moto Z Play since November of 2016, and so far have been enjoying fantastic batter life - generally around 8 - 10 hours over 2 or 3 days.
However, I had a nasty surprise a couple of days ago.
I charged the phone to 63% before I went to bed, and then turned it off. When I turned it on in the morning, it drained over the course of around 5 minutes (browsing reddit using swipe) to 14%. By the time I checked what was going on it was at 9%, and it had reached 7% before I decided to turn the thing off. Fun times.
I plugged the phone in with it still powered off, and it leaped straight from 7% back to 63% reported charge. Mighty strange eh.
I've not had this exact issue again, but I am concerned as my battery life seems to be significantly reduced when I compare it to before the incident. Watching youtube videos I am draining about 1% / 5 minutes, as opposed to the 1% / 10 minutes that I was getting previously.
There don't seem to be any rogue apps running, and I am slowly uninstalling anything that was recently updated, although I feel this is unlikely to be related to the issue.
I am unrooted, running the nov. security update in the UK. I have been charging using an Anker brand cable and power brick.
I was wondering if anybody else has had a similar issue to this? Thanks for reading, have a good day people.

With it jumping back up I'm thinking it's a software glitch. I'd back up my data, do a full data wipe /factory reset and see if that helps. If not, then time to call up Lenovo for a warranty repair.

thanks for that - yeah I agree, reckon I'll wipe and see how I go for a week or so. I bought through a good retailer in the UK, so hopefully getting action on a repair shouldn't be too much of an issue if it comes down to it.
Without much knowledge of how the technology works, it sounds to me like it's either a software glitch as you suggest, or potentially a bad battery.

Yep, those were my first two thoughts. Good luck with it!

Good luck beating this folks?

I was on a pace to get something like that yesterday - but I had to go to sleep so I could get up for work. Had 8:40 SoT over 17h off charger, with 46% left. If I could have stayed awake all night I might have made it! ?

[Q] Can't get a full charge!

Hey Folks, Just wondering if there are any other G2 users out there that have experienced this. For some time, I haven't been able to get my phone charges fully, and by fully, I mean something close to the reported norm of 97%-100%.
The hightest I got my phone was to 81% and that with a new battery, recalibration, and bump charging. In fact, I've had the phone powered off over night and upon restarting it, it was at 71%.
I've watched logcat to see if anything could be an issue there, I've installed ZDBox, (cool app, btw), and Battery Dr. The good news, is that after uninstalling a few apps and widgets, my battery life seems prolonged, (relatively speaking).
I'm running CM-7.1.0-RC1, 2.6.32.41-cyangenmod pershoot, and using the 26.06.2.27_M radio.
Since I couldn't get a full charge with it powered off, I'm thinking it might be a hardware issue or maybe the radio since so I might try 26.08.04.30 radio. Googling other forums, people were able to get a replacement phone from T-Mobile and some others said their motherboard needed to be replaced.
Any other ideas before I call T-Mobile?
Thanks!
Did you try clearing battery stats?

Yes, several times. Good call, though! By clearing the stats, I was able to get to the 81%.
Thanks!
Have you tried reflashing the rom? Maybe trying a different rom? Clear caches? I dunno I'm shooting for broke i guess....is it an aftermarket battery or stock?

Thanks, killj0y. Yes. I did that after posting. I did a Titanium Backup, then Nandroid backup, then wipe, superwipe, then flashed the CM7 nightly, (which is very slick, i might add). After bump charging I was able to get it up to 71%. I let it go down to 0% overnight and now I'm letting it recharge fully.
In about an hour, I'm going to call T-mobile and see if they have any other ideas.
It is an aftermarket battery but it behaves just like the OEM/stock.
You shouldn't ever drain your battery to 0% on purpose. You run the risk of the battery not being able to take a charge. Draining to 20% for battery meter calibration purposes is more than sufficient.
Yea plus aftermarket batteries can and do fail more often than stock. What brands is it?
Do you still have your stock battery? Try using that one and see how it acts. I'm willing to bet it's the battery.
The OEM battery I could never get above 71% and the new battery I have it up to 94% now and it isn't charging any higher.
I've had it plugged in for two hours. I have read the warnings about letting the battery drop to 0% and I agree, but I figure one time wouldn't hurt it. I got the second battery, thinking it was a problem with the OEM battery.
Ah! This happened as I was typing this. For the first time in a long time, the LED is green but the battery is at 94%, which I think might be okay.
Maybe the wipe/superwipe/reflash helped? I will keep you all updated and I sincerely appreciate the help and advice.

If that one time results in a battery that won't take a charge, then it hurts. Full discharge is also not good for the long term life of Li ion batteries. And it certainly doesn't help anything to run the battery to empty.
Yea I don't know how many times I've corrected people still quoting NiCd rules for Lithium ion batteries phone or otherwise lol. Anyways if the stock does the same thing it is probably the phone. Especially after a wipe, was it a clean reflash of the rom? Maybe that would work.
Here's my update. Kind of interesting.
So, by evening, my phone got down to 4% left of the battery. I plugged it in, (with my factory charger), and ZDBox said it would be 2 hours, 44 minutes until fully charged. Three hours later, it was at 45% full. I rebooted the phone and when it came up, it said it was at 86% full. Then I left it plugged in over night.
This morning, it was still at 86% and I rebooted it again, and then when it came back up it was 93% and within a couple of minutes, the LED turned green.
So, with this new batter, it *seems* slightly better, but I don't understand what's going on. This is weird, if you ask me.
The other bit of info is that at 7AM it was 93% and right now, (9AM, two hours later), my phone is at 72% with the majority of it being consumed by "Cell Standby."
I guess, since this is a new battery, there still might be some calibration/conditioning going on. I am still unsure if this points to a hardware issue with the phone.
Thanks again, for the help guys! I really wonder if I am the only person who is experiencing something like this.
Update: 19.09
Things have been a little better, but still not perfect.
I flashed CM7 Nightly, pershoot kernel, and 4.30 radio.
I have only been plugging in the charger when the phone drops below 20%. The phone only charges to 45% - 51%, then I reboot, and when it comes back up, the battery will read anywhere from 88% - 93%.
Once unplugged the batter rapidly drops down to the low 80's - mid 70 percentile and it stays in that range for a much longer time. Then once the battery drops below 40% is drains rapidly.
So, for example it says right now, "7h 54m 58s on Battery" and I'm at 20%. The breakdown is as follows:
Android system: 57%
Cell Standby: 12%
Wi-Fi: 12%
Phone Idle: 11%
Voice Calls: 9%
I'm really frustrated with having to reboot the phone to get seemingly get a full charge.
I think I am going to flash the latest nightly and then reflash the pershoot kernel and see where we are at that point. I still haven't decided if I need to call T-mobile since it could be a hardware issue.
It really sounds like a hardware issue to me. especially after several so many flashes and batteries...

Indeed. I called T-Mobile this morning and they are sending me a new phone. The guy asked me to inspect the battery, contacts, etc. He did ask me if I had put any "modified" software on it.
He also said, if they found modified software on it when they received it back at the shop, I would be charged a $108 restocking fee.
Quick, where's that downgrade guide!
Thanks for your help, everyone!
Update!
After I talked to T-Mobile, I downgraded my phone to the OTA Gingerbread and unrooted it, and turned S-ON. I admit, I was impressed with the OTA update since I had been running cooked roms since I got the think back in November 2010.
My new phone came today. Immediately, the battery behavior is completely different. I took out my battery from my old phone that said it was at 51% and put in the new phone and it said it was 80%. That's a good sign!
While we were at dinner, I got all the OTA updates, which really meant when I got home I had to downgrade it, but the guides here were really great, and I was back in business in no time.
I went with the latest CM7 nightly, the LEAK radio, and the latest pershoot kernel. I can tell already that battery behavior is much better.
Interestingly enough, on the stock gingerbread ROM, the DISPLAY was the major consumer of battery. Now on the stack I described, "Cell Phone Idle" is the biggest consumer. Maybe the stock T-MOUS radio is the best!?!? Who knows.
I hope this helps others who might be having weird battery problems. Have a great weekend!
I'm having this exact behavior where I can't get past ~73% without rebooting, then it goes to ~93%, which is about as high as I can get it. Guess I'll call T-Mo, I've seen it with different ROMs to I figured it was probably hardware as well.
Hey Thermalx, I hear you! The replacement phone I got from T-Mobile is behaves completely different. I have kept a charge +26 hours. I never thought I'd see the day!
Let us know how it works out.
Thanks!

I am so sick of this tablet...

Had to return the first one as the battery dropped so quickly I could see it - dropped by about 5% at a time every 2 minutes or so...
The one I've got now has been working fine (for the last 2 weeks) until today.
Turned the screen off at about 65% battery. Turned it on about 3 hours later and it had dropped to 43% without the screen being used. Mediaserver and Google Services had been using most of it apparently.
Rebooted it. It then went from 43% to 36% to 26% to 22% to 15% to 9% to 2% in about 5 minutes.
How can Samsung release something so useless?? Is it the software??
Wow that's f-ed up sorry about your luck.

No luck man.
I'm very happy with mine...

Hi. No, not rooted.
The battery stayed at 2% for ages. I then turned it off and on again, and the battery showed as 36% again. It then dropped straight to 23% which is where it is now.
Seems all over the place...

How long has it been since you did the reset?
Thanks
Have you factory reset and not installed any programs to monitor usage?
Perhaps something your installing is doing it. Are you using a microsd card?
I just starting charging my tablet after 1 day and 17 hours with 9 hours and 30 minutes of screen on time.
And I still had 18% battery left. I'm not saying it to brag just that battery life is fine on this tablet.
Until then please search Google for mediaserver battery drain. This is not running on my tablet btw.
Media server can happen if you have some corrupt media file the tablet is trying to read and identify over and over again

Threads like this are always interesting. If every owner on this forum's N10.1-14 performed like OP's don't you'd think it would be on the front page? So OP's issue is something unique. It could be:
A manufacturing issue that affected a batch of N10.1-14's. If OP's exchanging at the same place all their devices could be from the same batch.
Samsung uses different s/w in different regions and perhaps there's a battery draining s/w issue in the particular ROM OP's using. But unless OP's from Antartica you'd think others from his region would be reporting the same issue.
OP's loaded something on his device that's either incompatible with 4.3 or Exynos 5420. A lot of older legacy apps still run on newer Android devices but don't run well and create issues. If OP's using restore his old apps are being installed as soon as he signs in to his Google and/or Samsung account.
Of the three I'm guessng number 3 is the most likely. I have a SM-601 with 130 apps installed, a dozen syncs running, and two Exchange push account always downloading. Used exactly the way I used my N-8000 I'm getting about 10% less battery life. That seems about right to me considering the PPI is doubled, the SoC is more powerful, and I'm using also Samsung's motion, voice, and air sensors which didn't exist on the N-8000.
OP, try setting up the tablet without signing in to either your Google or Samsung account. That'll make sure no apps are installed without your knowledge. See if the battery drain is still there. If it's not, your issue is s/w and not the s/w pre-installed by Samsung. Good luck.
Thanks for the replies.
It seems there are 2 separate issues.
1. The mediaserver battery drain (I do have a micro sd card, but haven't recently added loads of new files or anything). The tablet has run fine for 2 weeks without this issue, and I haven't recently installed any new apps.
2. The fact that the tablet doesn't know how much charge it has - goes from 2% back up to 36% without being charged etc.
I'm not sure what to do. I noticed that google play music was running in task manager so ive disabled that, and have fully run down and am fully recharging the battery. When in plugged the charger in symbol went from showing battery empty to about 20% charged instantly which doesn't bode well...
If I still have an issue i guess I will exchange it a 2nd time for a 3rd unit...
Thanks for the help

Before this issue today I was happy with the battery life. My problem is not a general battery life issue - something is obviously seriously wrong with my unit...

I reset it once, a few weeks ago and its been solid with power usage since.
Perhaps it is being effective by the new Google Play Services, which appears to have a battery draining issue. This started in the last week, I believe.
The battery drain just happen recently, isn't it? I've just bought my Note for 4 days, on the first and second day, the battery is awesome, but from the third day it run down from 45% to 5% in minutes.... I think that related to some update service and happen to massive device recently!

Well, it is a possibility. My first gen Note 10.1 wifi does not seem effected by it. It is on 4.1.2. I also do not think this effects all devices. Wondering if it is a 4.2.2 and up issue or something along those lines. I only suggest it a possibility to check into.
http://forum.xda-developers.com/showthread.php?t=2378962
in here state that the problem could come from the new update of Google Play Store. I did remember that it is updated before the problem appeared (but not so sure). Just remove the update of Play store and see the result. Will report back
Just to update you all in case other people are having the same issue - I disabled google play music, ran thrbattery right down so the tablet switched off, charged back up to 100% and then used it normally. Battery seems much better. Although it did drain really quickly from about 35% to about 5%, but over an hour or so, not in minutes like before.
Weird apps have stopped using all the battery - its now used by about 90% screen, 5% android os etc which seems normal.
Still, there is always the worry that ill get it of its case one day when I nred need to use it and the battery will be flat!
P600 wifi getting 14 hour battery life here. Been using it all day and played some games too. Im happy with the battery life.
If people get together and help make knox proof root, I might be interested in making a rom with all my battery saving goodness in. Or work with some people to make a nice clean, lean rom. Who knows.

Battery Sudden Drops

Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?
Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.
So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...
How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.
I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.
Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.
Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.
I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag
I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!
Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.
Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.
I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten
Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.
Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.

[Q] Rapid Battery Loss & Rebooting Restores Battery?

So, my battery is wack... and I think it's only been acting like this since I went to a KK ROM? Maybe? Feels like it...
I've had this tablet since it was released last fall, and this behavior is very recent.
Anyways, it dies FAST. Like nose dives in a matter of 5-15 minutes. What's even weirder, is that sometimes, if I power cycle the device, it'll jump up by 30-60%. But then just dies again in another 5-15 minutes.
And there's a screenshot after I just power-cycled.
It jumped from 11% to 71%!!
Crazy!
I've also tried letting it get to 5% then charging it to 100%, done that twice. No luck. I don't know if this is related, but if I power it completely off, and plug it in, it turns on... kinda weird. My Note 3 doesn't do that, it just stays off and shows the battery charge indicator.

Anyways, it dies FAST. Like nose dives in a matter of 5-15 minutes. What's even weirder, is that sometimes, if I power cycle the device, it'll jump up by 30-60%. But then just dies again in another 5-15 minutes.
And there's a screenshot after I just power-cycled.
It jumped from 11% to 71%!!
Crazy!
I've also tried letting it get to 5% then charging it to 100%, done that twice. No luck. I don't know if this is related, but if I power it completely off, and plug it in, it turns on... kinda weird. My Note 3 doesn't do that, it just stays off and shows the battery charge indicator.

Hi, I have similar problem and I am with 4.3 android. I have battery loss when I play games. It drops to 2-3% really fast and after reboot it goes up to 35-40%. Once I fully depleted my battery and charge it. This time there were no battery lost. After the second charging problem persists.
If you manage to fixed it please tell us how.

Well, I doubt that I can do that since I have a Custom ROM on my tablet

I have a similar problem with my p600. the tablet is new, got it since a month or less.
at first i was amazed of the battery life i use it a lot for work writing documents and sheets on excel, battery used to perfom quite well giving me more than 5 hours of screen on, but recently the battery starts to drop very fast, now i can barely get around 2 hours of screen on.
i've already done 2 cycles of full discharge and then charge it completely with the tablet turned off. but the problem stills.
also sometimes when i reboot the tablet the battery goes from i.e 20% to 40% after the reboot.
im still looking for a fix or solution, today i found a new official firmware for my model (4.4 firmware for telcel mexico). going to wait until the tablet is fully charged and then flash the new firmware. I dont know if its going to help but i got nothing to lose.
by the way, sending it to semsung is not an option because of knox 0x1

try this, bring life back to battery. If you use the trial version, keep exit and redo it until all cells are done.

Well unfortunately this has not worked....battery is still tanking. last night i played plague for 30 minutes....in 30 mins battery went from 90% to 25%. I think i will try reflashing KitKat....maybe my original update was screwy. If that does not fix it then I guess I will have to call Sammy.
Man i ha e exactly the same problem. I calibrated it some months ago and it seemed to work fine. Now the problem is back.... Dont know what to do... I have tried several apps, though i read google doesn't recomend to use any app to fix the battery... we really need help here

Bumping up I have the same exact problem... any fixes?
Sent from my SM-P600 using XDA Free mobile app
Sorry to bump this, has anyone found a solution yet.
I've replaced the battery 3 times in about 9 months, but had this issue about a yr, was sent back to Samsung who changed the battery and supposedly updated the fw 4.4.2, I have since replaced the battery another 3 times every 3 months, each time either factory resetting or flashing a new rom, currently on official Smp600 5.1.1 BTU rom, today my battery was on 47%, I plugged in charger and was watching/streaming a movie on it, about 80 minutes later the tablet shut off, which was odd it's never powered off while on charge, powered it back on and battery said 19%, my previous issues has been the same as others, it can be on 100%, play a game, or stream a movie,or watch youtube etc and it will nosedive dramatically 20/30% at a time, sometimes within 10 mins it's gone from 100% to less than 30%, it's clear there's some sort of issue if others have it, I was wondering if a thread should be made to list ppl with this issue to see how many there are and go from there.

I've been having the same issue for some time now. Calibrating the battery does help, I don't experience the problem nearly as much after calibrating it. But it'll still nosedive on occasion, maybe once a week. This is the app I use to calibrate it https://play.google.com/store/apps/details?id=com.nema.batterycalibration

Sudden battery drop

Good morning all. I have owned this device for a few weeks now and am enjoying it immensely. I bought it second hand from swappa. The warranty/ownership was transferred to my name.
Twice in the past few days I have had significant battery drain. The level indicated 60% when I started running. I watch Netflix or the like for 45 minutes or so then I get the battery saver notification telling me I am down to about 5%. It makes me worried that this happened more than once.
I am wondering, should I suspect faulty hardware/battery? And if so, should I rma? I attempted to clean flash October factory images with no improvement.
Thanks and have a nice day.

I would install Accubattery and let the phone go through a few full charging sessions. Try to start charging above 20%. Don't take the phone off the charger until the APP tells you the phone is full. You will notice the phone continues to charge even after the PHONE says it is 100%. Once you have done this a few times you will see your battery's estimated remaining capacity as compared with a new battery under the Health tab. It will show you both the mAh and percentage. This will rule out the battery. If the battery is good (eg. >90%) then try a factory reset. Might as well wait a few days until we get the November security update on the 5th. Good luck.

I have faced the same issue since 3-4 days...the battery is draining a lot faster.
