Battery life is plunging from 80% to zero

Hey all,
About three weeks ago I had a strange problem. I noticed that in two straight charge cycles, my battery life plummeted from about 80% to zero in just a few hours. I'm not sure what the issue was. I hadn't changed settings, installed new apps, etc. My first screenshot shows an example of what happened. 4G and data were off during the entire time.
Since then, things have been okay. I typically get 3 days standby with 4G on and light use, or 4 days with 4G off. That's mostly standby with maybe an hour or so of talking and minimal use.
After those strange battery plummets, I installed and used GSam Battery Monitor to get more details about what processes were running on my phone in case I noticed the sharp drop happening again. Everything had been fine for over two weeks, with me getting expected battery life before this issue and not experiencing any odd, sudden drops (maybe 5 or 6 charge cycles). This lends me to conclude that my battery's charge capacity is okay, and calibration also shouldn't be an issue.
However, the problem arose once again a couple days ago. Went from 75% to nothing in just a few hours. 4G was off during that time. The third and fourth screenshots show the same issue. Charged my phone, and this morning the same thing happened yet again. At about 90% the plummet began, and within an hour or so I was at 75%. At this point I took screenshots of Android's battery status, and I also did the same for GSam to show what apps and processes were running. The phone's temperature seemed fine.
The GSam screenshots taken when the phone was at 75% and dropping are in the next post, since I'm limited to four images in this one. I have no idea what's causing this massive, sudden battery drain. The only thing I can think of is that I've done Verizon's OTA updates, but otherwise pretty much all my settings, apps, and usage are the same. Plus, for two weeks I had normal battery behavior, so I'm completely baffled.
I also know that cell standby is incorrectly reported in the GS3 battery screen, and I'm getting a good signal where I live so that shouldn't be a problem. I forgot to get screen time for the first case (first two images), but it shouldn't be more than 10-15 min there since most of the charge was lost due to the freak plummet.
If anyone may have an idea of what's going on, or if there are some tools/tests I may use to figure this out, I'd really appreciate it. I turned off my phone after taking the screenshots at 75%, so if I need to turn it on and check something for you I can probably do that. Thanks a lot.

FYI, here are GSam screenshots from when the battery was in the process of plummeting this morning.

i think you built in battery status settings are off. i barely get 12 hrs with medium use, so what i think it happens is that the battery monitor is not showing the proper discharge, and then all of a sudden it catches up to the discharge rate.
are you on stock rom, rooted, unlocked bootloader?

I am stock rom. No rooting, no unlocking.
These plunges are definitely an anomaly. Truly, with me barely using the phone and turning off mobile data, I get a few days of standby. I've had the phone since July, and the aberration in battery behavior has been the steep plunges I've shown.
In between these instance of steep plunges, I've had normal use. I really don't think it's an issue of calibration. Please believe me when I say that my normal, light use during the past four months gets me anywhere from 3-5 days with me barely using the phone. When I say barely using it, I mean not even touching it for an entire day if nobody calls me. But now, a sudden plunge in battery life is happening at 80% with no apparent reason.
I think it might be some kind of software or hardware glitch, but it's impossible for this to be normal given the battery life I typically get. Just looking at that steep drop, it's crazy and just happens out of nowhere.
But please trust me when I say that these sudden plunges that have happened a total of 4 or 5 times, causing the battery to drain completely in a few hours when I'm not touching it, are quite a drastic aberration from the normal standby life I get. Something is definitely wrong here, I just don't know what.
And one more thing to add is that after this sudden plunge and rapid drain, charging the battery still takes the normal time it does when I'm not having this issue. That is, about 2.5-3 hours to reach a full charge (and I charge with the phone 'off'). The battery is being completely drained. But this happened twice, then didn't happen for maybe 5-6 charge cycles, then happened again twice.
Before the first instance, I remember an OTA Verizon update around 10/5. My phone was okay for 2-3 charge cycles after that. Then two rapid drains. Then 5-6 normal cycles. Then two more rapid drains. There was a second Verizon OTA update somewhere in there but I can't remember.

and you said it only started once you did the OTA update from verizon right? well you could either try to go back to the stock verizon rom pre-update and see what happens there, or contact verizon and let them know what happens with the new OTA update. they could replace your phone, or it could be a bug of the new OTA update. i am on stock rom and rooted and deleted the apk that kept on trying to push the update. just unlocked by bootloader and so far my battery life has improved compared to previous locked bootloader.

i would take it to a verizon store and show them. They might give you a new battery.

I may have to do that. I'm just not really sure what the issue is.
- The battery can still hold a full charge.
- Based on running services, nothing is causing high CPU usage.
- The sudden plummet almost seems kind of random.
- Since there have been normal charge cycles, it's not an issue of calibration.
I'm not sure if this is a hardware issue or software issue. I'm trying to wrap my brain around what could cause the battery to drain so suddenly and sharply. Could the charge somehow be "leaking"? But in that case I'd expect it to happen all the time. If there's an underlying software issue, is there any other tool I might be able to use to figure it out?

Does the phone get hot?

Not from what I can tell. Note that the first couple plummet drains were overnight.
But today I caught it before noon. The phone wasn't hot, and the GSam screenshots show no CPU stress.

Maybe you can do a factory reset and se if that helps. They will probably do one if you bring it to verizon anyways. It sure sound like a hardware problem. You'd think if the processors are working that hard that the phone would get hot, I know mine gets pretty hot sometimes under heavy use.

Thing is, all indications show the CPU isn't working hard, and the phone wasn't hot.
I'm stumped.
This is a noobish question, but I presume the only way to go back to stock is to factory reset? One thing I might wait for is the Jelly Bean update, presuming this random drain holds off until then.
But yea, I dread going into VZW because they're just going to try to pass this off onto me doing something wrong, or me not knowing how to calibrate the battery, etc. The information I've provided in my OP and in the screenshots would fly over their heads. Maybe I can just do an online chat and tell VZ to send me another battery?
The only other thing I can think of is that sometime before these plummets happened, I went online to MyVerizon and turned off the Backup Assistant for movies/music/etc. so I wouldn't get all those notifications. I don't think this could be the issue, since the plummet happens when data is off. Plus, GSam would show that Backup Assistant is hogging the CPU or forcing a signal.
I doubt swapping batteries will fix it, though. I'm thinking my internal hardware might have a serious problem.

Before the update, was everything normal?
Is the update with the HE base/baseband?
It probably isn't a hardware problem, just a bad base.
I've noticed after updating my GS3 to the HE base and the battery life was just horrid.
It's said that the new HE baseband uses up more battery also

Sorry, I don't know what you mean by "HE" base/baseband.
But yea, this problem didn't come up until after an OTA update.

Check your baseband version under Settings -> About and paste it here
Sent from my rooted Verizon Samsung Galaxy SIII

It's I535VRLHE
Kernel version: 3.0.8-1092717
Build number IMM76D.I535VRALHE
I turned on the phone and within 10 min or so the battery life went down by 2-3% without me doing anything. As a test I've put it into Airplane mode, and it's decreased by about 2% in 45 min.
Now I'm wondering if I have a faulty antenna or something.

Yup ive had it drain 90% overnight many times for no reason. Called verizon and my new battery should be here today.

1+ day on battery and only 11 minutes of screen time?!?

HE is the baseband version and the build number. For example I have: Android Version: 4.0.4
Baseband: I535VRLG7
Build: IM76D.I535VRALG7
which is the version before the update.
Like everybody else said, call Verizon or go to a store and let them know about the battery issues and they should send you a new one. Or even call Samsung and tell them you bought an S3 through Verizon and you are having battery hardware issues.

Well, no calls made or received during that time. No data being used.
So, wasn't really using the phone during that time...

Battery drain overnight and general issues

I've been experiencing battery issues lately and I struggle to find a solution for it. When I first bought my Xperia Z3, battery was wonderful and was lasting over 2 days with moderate usage. Now, I am forced to charge it every night and it often dies even before the end of the day.
Every night, I charge my phone to full before going to bed and notice in the morning that 30% of the battery get drained overnight.
Since then, I have tried many things but it didn't solve my issues:
- Did a factory reset
- Disabled every widgets
- Kept apps to a minimum
But my battery is still draining overnight (and in general).
I installed GSam battery monitor and it seems that no specific app is draining the battery.
Here a more pictures for details: img ur.com/a/eqsuq#0 (copypaste as imgur, can't post link yet as I'm a new user )
What could be the source of my issues?
I'll be so happy if you could provide me with a solution. Thanks!

what firmware are you using?
I had the same problem after flashing a pre-rooted stock 5.1.1. The only solution I could find was to do a full wipe and flash a pre-rooted 5.0.2 now things are back to normal for me.

I'm running stock 5.1.1, unrooted. Never flashed anything before.
So if I understand correctly, you flashed a 5.0.2 and then let it update itself to 5.1.1?

no I flashed a stock 5.0.2 and have stayed on that. Disabled software update so I don't get OTA updates. Everything back to normal on 5.0.2. Won't update until a stable Marshmellow comes out. For me heat and overnight battery drainage problems made 5.1.1 a nightmare. 5.0.2 is rock solid.

I see. Damn that really would be a last resort for me, seems like a lot of work just to resolve the battery issues. I hope someone can come up with a fix because surely the Z3 is working perfectly under 5.1.1 for most other users.

I have seen the battery drain pictures and i see there is a solid blue line awith the Wifi awake option. I have experienced it before.
What you need to do is perform these steps and then report back.
1. Go to Wifi settings>Advanced>Disable "Scanning always Available".
2. If you don't want to recieve notifications when screen is off then also set the "Keep wifi on during sleep" to ALWAYS
3. Enable Stamina mode and use EXTENDED STANDBY
Check if the solid blue line cuts in between when screen is on and off.

Update on the situation:
You were totally right. My phone lost less than 2% overnight after following your steps. Moreover, the battery has been great so far with moderate use, standing at 60% remaining with more than 2 hours of SOT (2 hours SOT put me at around 30% remaining before).
Thanks a lot! Strangely, the history details screen still shows Wi-Fi as a solid blue line.
Here are some screenshots: img ur.com/a/zqG0E
First part shows the stats when I woke up in the morning, second part shows stats at the end of the afternoon.
Ideally, Stamina mode wouldn't be required but I think this is a good compromise until a fix comes up.
EDIT: After a second night in Stamina mode, it appears that I lost 30% overnight again. The only significant change I can think of is the fact that I added Whatsapp as a standby app so that I can receive messages when my phone screen is off. I will try to remove the app and see how it goes tonight but if I cannot put Whatsapp as a standby app at all, then it will be terribly inconvenient to not be able to receive messages instantly without having the screen on.

Battery Issues -> 32.2.A.0.224

I know I can look desperate, but this problem is driving me crazy.
My battery was good (but not perfect) in Android 6.0, but this latest update .224 is horrible! I have the same apps and the same use and with a maximum of 3 hours SoT! In one hour of normal use lose almost 10%!
Some people are having the same problem: http://talk.sonymobile.com/t5/Xperi...ues-32-2-A-0-224/td-p/1137290/highlight/false
I did not clean install of 6.0 to 6.0.1. I just did clean install of 5.1 to 6.0.
There are people who did clean install and are having the same problem.
Someone here is going through the same problem?

Hey, I had the exact same problem as you (UK Generic) and I did a clean install as well. I had to do a factory reset after installing and it took about 2 days for the battery drainage to settle down. Yesterday I got about 4 hours of SOT. I usually get around 2.5 days of battery which is similar to the previous firmware.
Try a factory reset.

To be honest, I'm getting the best battery life I ever had out of that smallish 2,900mAh battery + power-hungry Snapdragon 810, since .224
I still don't get the battery life I had out of my OnePlus One (that thing was a beast), but it's better. I get home after work with between 25% and 35% battery left now. With Lollipop and Marshmallow 6.0, pre 224, it would usually be between 15~20% (25% on good days), same usage pattern.
The Z5 is still not a very good phone in the battery life department, and probably neve will be, but it's better now.
One important thing though: I clean-installed .224

I turned off once and giving reboot again, but had not resolved! The system android was 9% and then increased to 14% of battery usage. Is now 6%, ie normal.

I got 4 hours 40 minutes of SOT today, from 100 to 2%. This was mainly browsing and some videos over the span of 10 hours. If I'm lucky I can get 12 hours overall but with only 2-3h screen on time, as I don't use the phone as often.
I noticed something odd today - Wifi is now showing at he top of my usage details and it shows an entire span of Wifi usage (from 19 days ago, I think that is when the phone was updated). It has no impact on the battery life but it's just odd that "screen" doesnt show on the top anymore. I rebooted and the same thing occurs.
The battery usage screen really sucks now - you can't even see if the phone is "awake" or when there was wifi/mobile signal etc.

I got over 7hours with WiFi connected, Opera browser to read wattpad and my phone still had 27%. I've just unplugged my phone 2 hours ago and used it to surfing GG+ and Facebook, 20% for 2hour and 10mins usage. So it's good or bad? This result is a little better than my old Z2.

Same thing here. I usually have up plug in mid of the day just to make sure i have enough juice to survive the night. Around 3 hrs SOT only. Even with the auto sync off and wifi scanning off. Location service is off too. I don't see why the standard stamina mode has been removed that usually prolongs battery. I have doze installed for mobile data minimized but still around 3hrs or so

Which option do you see it?

With normal use, (browsing, social networks, videos, etc) I lose about 10% -15% per hour which I think is normal because I use it a lot. so it may last about 6 - 8 hours until it reaches 20% and I charge it immediately, I only drained the battery from 100% to 0% one time. Because I read somewhere full drains are not good for battery. Anyway if I play games, for example Need for Speed No Limits, I lose about 20% in an hour or so. so if I keep playing it will last only 4 hours aprox. maybe less. But there had been days where I almost don't use the phone and it lasts all day. So I really can't complain. But it certainly doesn't lasts 2 days as Sony said

Got the new update promise to fix batt, did you guys update?

Without any changes on usage type (I cannot say its regular on everyday, but I can say that there is no difference between last update and and previous one) battery performance on last update is about half of the previous one! Even if the stamina mode is activated, draining is very fast on my device (z5 compact). Draining on stamina mode is larger than normal usage on normal mode (prev version). In short, this problem is very very bad on my phone. I'm wondering when this issue will be solved or this is just happened on my device?

Have to keep it in your mind.

I did clean install of .224, wipe everything. Let the battery dies completely and recharged up to 100% without stopping. I had a significant improvement in battery life!

Has there been any fixes to the battery drain issues with 7.0 update on Honor 8 (US)?

Hi, I have upgraded to Android 7.0 on my Honor 8 yesterday and since then the battery is draining at an insane pace.
I used to get an overnight standby drain of 3-5% on average with 6.0 and it is well over 25% with 7.0. Something called "Android System" has consumed a disproportionate majority of the battery. A similar problem is reported here: https://forum.xda-developers.com/honor-8/help/battery-dropped-40-nougat-honor-8-t3558197
The background app settings haven't been changed -- have about same 6-7 apps like Whatsapp, Outlook, etc. However, when I open the current background apps, I see a few unprotected apps (like Maps) also running in the background. Is this a bug?
Please help out, if there are any fixes.
Thanks.

Many users are dealing with this problem and I've reported before.. This update is broke, and shouldn't have been pushed officially. There are a lot of bugs, and the most irritating one is the battery consumption.
And I don't think Honor is going to fix any of it since we're used to them not caring about what we deal with.

My personal experience with the Nougat update was that battery drained quicker than usual for the first few days, then it stabilized to normal levels (i.e. more or less what it had been in Marshmallow). I was expecting this behaviour, since system upgrade clears out battery optimization data, and it takes a couple of days for the OS to learn what to optimize. Also I suggest you recheck your battery saving settings (Both the Huawei version under Battery settings and the Google version under Applications).
And since someone is going to ask anyway: no, I haven't done factory reset. There was no need.
But this was just my personal experience with nougat. It's of course quite possible that for some people there is a real constant battery drain (wouldn't be the first time, I had a similar experience with my old Motorola when I upgraded to Lollipop a couple of years ago).

It's not the update. From my experience, I had this issue since I bought the phone. I would factory reset it all the time and this issue would persist.
It turns out that in my case, I would always turn off LTE and use WCDMA instead. My logic being that WCDMA uses less power, so therefore I would get better battery life. Nope. There's a glitch that happens if you do this and have wifi on, It doesn't let the phone go into deep sleep. Ever. So your battery drains about 20℅ overnight.
The solution for me was to simply leave LTE on, and now my battery consumes like 1℅ overnight.

For those suffering from battery drain, check your consumption and see if Google calendar sync is taking up a lot of it.
I had that issue, and had to manually kill the sync (from the accounts screen).
It seems to be an issue on all Huawei devices on 7.0, the native calendar isn't playing well with sync, and unless you're rooted and can uninstall it, you're stuck. (I'm waiting to root until a patch comes out for all these issues first)
All in all, if this is how Huawei treats their devices, and their customers, I won't buy another one of their devices.
I updated via Charles method, but my mother's L04 still hasn't gotten the update. And probably never will unless I do it manually.
Very disappointing.

My personal experience with the Nougat update was that battery drained quicker than usual for the first few days, then it stabilized to normal levels (i.e. more or less what it had been in Marshmallow). I was expecting this behaviour, since system upgrade clears out battery optimization data, and it takes a couple of days for the OS to learn what to optimize. Also I suggest you recheck your battery saving settings (Both the Huawei version under Battery settings and the Google version under Applications).

Thanks. I was thinking of waiting for a couple of days too. Its just been 12 hours and the battery is almost down to 25% from 100%. If it doesn't improve in the next few days, I'll revert to 6.0 with which I had solid 1.5 days battery life for my usage level.

On my frd 09 i got a update after the nougat update which fixed my battery drain it was around 356 mb big. But since maybe 1-2 weeks already. And my battery drain is lower as on MM

I do feel Nougat on my L14 is draining faster than MM. It's mostly Android System or Android OS so I have no idea what is within that taking the power. There is also a weird bug with LTE enabled when I make a call to another cell phone. Most of the time, my phone says it's ringing on the other side but there's no "ringing" sound on my side. Weird. Turn off LTE and you can hear the ringing.

It is always hard to determine what is going on in these sort of circumstances. For me, EMUI 5 doesn't seem to have badly affected my battery life. I just got almost 3.75 hours SOT using Waze for navigation, and still have about 30% battery. According to the detailed power info, Waze was using 1340.27 mAh.

Just for balance, my experience is more like this one, although I don't think I had to wait days for it to not be a battery drainer. Is everyone in this thread talking about b360? (for whatever variant you have)? I did see this on b320, but have used b360 for about 1-2 months now (Charles) and haven't had any noticeable difference in battery life from Marshmallow. It drains 1-3% / night. Screen on time , say browsing is pretty regularly 5.x hours, and typically I get 2-3 days out of a charge.
I believe everyone that says they've got a problem, but I guess some of us got lucky. Just so it's known: Mine is a US L04*b360 variant.
Note: Just as a possible point of difference. Before I was on b360, I had the phone rooted, with TWRP, and had to wipe the entire thing , rollback to b160 and use Charles to get b360. I never did a reset and I don't turn off functionality. Also, maybe most important. I don't use social media hardly at all. I haven't got Facebook or Twitter installed because I don't like either.

i would suggest a factory reset, then install only essential apps and test it for a couple of days.
L04 here, OTA updated and I'm seeing better battery performance than MM.

Hi, I have upgraded to Android 7.0 on my Honor 8 yesterday and since then the battery is draining at an insane pace.
I used to get an overnight standby drain of 3-5% on average with 6.0 and it is well over 25% with 7.0. Something called "Android System" has consumed a disproportionate majority of the battery. A similar problem is reported here: https://forum.xda-developers.com/honor-8/help/battery-dropped-40-nougat-honor-8-t3558197
The background app settings haven't been changed -- have about same 6-7 apps like Whatsapp, Outlook, etc. However, when I open the current background apps, I see a few unprotected apps (like Maps) also running in the background. Is this a bug?
Please help out, if there are any fixes.
Thanks.

Try going into settings, accounts, google.
Look to see if anything looks like its stuck syncing. If there is, turn that off. Go into the app that was stuck, and swype down to cause it to refresh, then go back into the setting and turn that syncing back on (if you want it to sync).

Does root and Greenify help?

I contacted Honor Support and reported the problem.
I was suggested to "Wipe Cache Partition". It helped a bit but the battery was still draining at a faster rate than 6.0. So I have now been wiping cache partition on a daily basis after a full charge.
I know it doesn't make much sense but it helps contain the drain a bit, at least when connected to the Internet via WiFi. The drain rate remains the same as soon as I switch to LTE (about 2-3% drain per hour with roughly 5-10 minutes SoT).

My phone wasn't rooted. I'd have tried Greenify but it wasn't any app causing the drain; "Android System" is the culprit. I don't know if Greenify could help with that.

Thanks for your comment. I checked the settings; there are no issues with sync.

Thanks for your comment. My model number is: FRD-L14 and the build number is B360.
Honor Support recommended to "Wipe Cache Partition". I did that without much luck. I have now been wiping the cache partition after every full charge (which is a ridiculous thing to do!). It does help arrest the drain a bit but only on WiFi. As soon as I turn on the Mobile Data, the battery drains at insane speed (about 2-3% an hour with just 5-10 minutes of SoT).

Severe battery drain on s10e. Any suggestions or solutions?

I've been using the phone for two weeks now and the battery drain has gotten pretty horrible the past week. I charge the phone up to 100% and leave it off the charger as I go to sleep from 1am - 9am.
I wake up and my phone has 70% battery left with wifi/data off. [Battery drain](https://i.imgur.com/VkAcAqd.jpg) [Google battery drain](https://i.imgur.com/qjxMkN2.jpg)
Does anyone know what I can do? Is there an app with which I can check on what's draining my battery?

You can check which apps is draining the battery.
Just go Setting, then search for "Device Care", then hit "Battery" -> Battery Usage

All S10 phones have a bug that is causing them to not deep sleep when screen is off, causing poor standby performance. This is caused everytime you receive a VoiP call, so after you receive one, just restart the phone. Being caused a proximity sensor bug.

Try off Biscuitby feature

Try to wipe disable Google app and check battery consumption. If problem persists, try to wipe cache from recovery and if necessary do a factory reset, 30% battery drain in a night without network connections is not normal. If all attempts fail better go to Samsung assistance to change the battery

7hrs: 10% when sleep, wifi on. Not good but I think it is not too abnormal. I think, samsung still have a lot of bloatware!
But on screen I thnik is OK: 5-6h mixing, 3000mA battery on a strong SOC, it's normal. My back up Huawei GR5 2017, 3400mA, it is the same time!

This solution was posted on the S10 forum and certainly helped me.
There's a bug that stops the phone from going into a deep sleep mode post making a call (audio/video) on apps like WhatsApp, Skype et al. The solution for the time being is to reboot the phone once before going to bed. I tried a lot of other things but had a ~2% hourly standby drain which reduced to <5% overnight after figuring out this solution. I have both WiFi and Bluetooth on at night.
You may try to play around with the battery saving tweaks in ONE UI but nothing worked as well as this has. Hopefully there'll be a more practical fix to this soon.
Cheers!

Being as this affects voip calls, does this mean wifi calling is affected too? I mean, that's technically voice over IP.

I tried to debug battery drain using Battery Historian. I noticed that the phone does go to Doze mode completely, but for some reason, CPU stays awake. I'm still new to the tool, will try to find out more about why CPU is kept awake all the time.
I get battery drain regardless I make any VoIP call.
Another issue I noticed is PUBG lags horribly on the phone. I tried different combinations of graphics settings, the game was still lagging.

Just tried pubg...hdr +ultra runs ok for me. No lags, maybe sometime stutters for a sec.

For the first launch, the game runs very smoothly, lag starts after that. The more I play, the more lag I get.

Putting the phone on battery saver mode barely drains any juice (Medium Power Saving mode), seems like it's just a software issue and not hardware specific issue.
By the time Samsung releases any fix, we might have to live with this one.

Since the update this last day or so, my battery is lasting way better than previously.

Which region you are from? Is your phone unlocked? Is it Exynos based?

What update? Can you share the info that came with it? My SM-G970U1 is still on Feb. 1, 2019 patch. Although I don't have any problems with battery drain, pulled out two screenshots lately, both over about 12hrs period, one was with cellular radios on and the other just an airplane mode:

It's mostly Exynos people or the Sprint USA models \ service. No one else is having it really.

Got the March update. Exynos version. Battery drain seems a bit better at first glance. But it's not been long since the update. So not completely sure.

Got the phone today and the battery sucks lol and got an update today as well

My Snapdragon S10e never gets less than 4 hours of SoT under the heaviest use (I am constantly messing with settings, installing\closing\uninstalling apps, etc etc)
If I use it "regularly" just browsing Reddit and such, with a normal phone signal, I get 6 to 9 hours every time.
I don't use dark mode until Sunset.
I leave NFC/Bluetooth/Location on at all times.
