[Q] Why Battery Draining Fast?

I have owned this phone for about 3 days, but I have some battery issues.
I attached 3 pictures, and on the first picture, you can see there appears to be no wakelocks, but on the 2nd picture, the Android OS used the vast majority of my battery life, and the 3rd picture, Android System has a lot of "Wake Up Device" (i don't know what the number means is it minutes?)..
I have uninstalled/disabled most of the apps I don't need, and have the brightness set to low, and on airplane mode with all sync off, and zenmotion turned off, and this still happens. I lost about 11% battery overnight with this problem. It seems like when I am using the device, the battery drops a percent every minute even when I am just scrolling through the Settings.
I only used about 1 hour screentime on this phone and the rest on idle.
I already installed both system updates.
Does anyone know why this happens? I know there is a memory leak problem, but I saw on another thread other people don't have that bad of a drain anymore...

For battery draining assistance see ZenUI app called ASUS Support: Apps/ASUS Support/Assistance/Battery/Battery drains fast/follow detailed troubleshooting steps. If battery still draining, recommend updating to latest firmware version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Mine seemed fine for a week and then I got this today. Pretty much done with it. Can't even get it to factory reset.

I have zenfone 2 and at the 1st week the battery drained very fast but then after I Updated all the aps of Zen Ui i noticed improvements to my battety life. go to settings and go to zen ui instnt update and update all the apps. now im using my zenfone 2 whole day surfing from 9am to 7pm and i still have 30% battery hope it works for you too. try it

hello guys i am getting screen on time of mere 2 hours without any significant use on my ZF 2.... i have stock rom. no root nothing.... can anybody help me

Battery drain issue still not fixed with updates???

Disable PC Link and Party Link default apps, worked for me. They're default apps using cpu all the time like they're SO Android... Disable all default apps that you don't use too

I've got here two brand new models, which differ only for touch and battery version (Z2C3 01040005 1525 and ... 1526)
The 1526 doesn't show any drain. The 1525 does, as of its very first boot. I tried keeping same settings of course.
I'd like to point out that when connected and charging it shows big steps like going from 63 to 72% and it also reaches 100% in less than 60 mins.
When disconnected the discharge path exhibits about 1:15min of operation.
May I suspect the battery is defective?
PS: after a factory reset from recovery seems have fixed the problem for now at least...

Asus Zen phone 2 laser battery drain ?
I made an account with this website and took the time to write this, so I can let users who own this phone know one of the
biggest battery drain features I've found......DISABLE HOMESCREEN APP MOVEMENT SENSOR, in app icon settings.
When you tilt your phone app icon adjust to the tilt, yes looks cool until you realize how much battery you could save by leaving then static and not constantly running a fDucking tilt sensor.

Battery Life issues on MM

After updating to MM from STOCK LP, my battery life has gone way down... by hours. Now, LG and Verizon boast that the MM update will help EXTEND battery life, but it has done quite the opposite for me. I like some of the new features such as WiFi calling, but not at the expense of hours less on battery usage.
I've done a factory reset, and even re-flashed the stock MM KDZ, but my battery still dies quite a bit faster than on LP. 35% of battery usage is the screen, and it is on auto... next at 12% is Google Play Services.
Any ideas on how to boost my battery life?
If nothing works, I'll just flash back to LP and root.... I like MM but not at the expense of my battery life.

Hey, I've got the MM update. I didn't get to test too much with lollipop but here is what I've done to maximize my battery.
1. hard factory reset
2. wiped cache
3. disabled all useless apps like amazon/amazon kindle/amazon music/android pay/audible/cloud/google play books/google play movies & tv/google play music/google play newstand/google+/hangouts/nfl mobile/slacker radio/vz navigator. (your list may vary depending on what you find useful)
4. keep screen brightness at 20% and as low as allowed when in sunlight
5. turned off all GPS
6. Under settings/location/3 dots in top right corner/scanning/ disable wi-fi scanning and bluetooth scanning
7. If you use facebook uninstall it and messenger then go on google chrome and log into facebook there and select get notifications then click the 3 dots in top right corner and click add to home screen while on facebook, it will put a short cut on your phones main screen allowing you to go right to facebook.
8. if you don't have a lot of people sending you MMS messages (picture messages through regular texting) then disable mobile data when you're around wifi.
I just removed facebook and messenger today so I'm still testing the battery now. But yesterday with facebook and messenger I had a total of 3.5 hours of screen on time. Today so far with facebook and messenger gone I'm at 90% battery with a total of 1h screen on time. which is 50% screen.

Thanks for the reply. I've done almost all of these, but I cannot wipe my cache because for whatever reason my phone will not boot into recovery mode. I've dialed all useless apps. I'll try the Facebook thing. I keep my screen brightness low now, although on LP I kept it on auto with no problems. LP also seemed to kill my mobile data while I was on Wi-Fi automatically, this doesn't appear to be the case on MM.

When trying to clear cache are you turning the phone off and then holding down power+volume down until the clear cache screen shows up? That's how I do it. And yeah the LP and MM both kill the data if you don't use the advanced calling. The reason is the G3 was one of that last phones to include dual radio chips. You're lucky that you're on a monthly plan. People like me on a prepaid plan aren't allowed to activate the advanced calling to use data while in a call. It's honestly dumb. My S5 could do it without needing advanced calling. Just one of the few things that irritate me about the G4
1. lack of data while calling
2. can't record video at 60fps unless rooted
3. verizon took away the ability for MM to use MicroSD card as internal storage.

I was able to do it by holding down vol. Up and power. I was trying to do it releasing power for a second, no wonder it didn't work. So I wiped cache. All I heard was about how good the G3 was, so I bought the G4. I really do like the phone, but this MM upgrade isn't working out too well with battery life. And now that it looks like there will be no root for MM, I'd consider selling it, but it's not paid for yet.

I can't vouch for it. But I have heard other peoples MM updates working it'self out over a few days. But I couldn't really say since mine has seemed decent from the start. I only got my phone in the mail a few days ago. First day I had it within 10 minutes of turning it on it updated and then updated again to MM. Then each day I've used it it's had similar battery usage. 76% battery remaining, screen on time is 1h 52m 53%

Looks like you should get around 3.5 to 4 hours of screen on time. And if you're keeping yours on automatic brightness you may be doing better than me. Not to mention I don't even have the facebook or messenger app on my phone like most do.

I can definitely tell a difference between LP and MM with auto brightness, and LP used less percentage of my battery. Facebook and messenger don't use up much battery because I've stopped push notifications, and I'm not that active on Facebook.I guess I'm spoiled because on LP I could go more than a full day on a single charge, and now I get about 8 hours being ultra conservative.
I'm just kind of bummed about the phone in general. I love the hardware, but I'm not at all used to not having root. I was a Samsung fanboy until the S5, which I had 3 of (junk).

From the way everyone talks about lollipop I'd downgrade in an instant if I knew I could be certain I wouldn't bootloop. Since I don't get to use advanced calling there is no reason for me to want to keep MM. Especially if I could root the phone and get 60fps recording as well as customization. I just don't know how to do the KDZ or LGUP thing. I've rooted phones before using odin and also towel root. But now that there are two ways that I understand of going about it being the KDZ and or LGUP I don't know which to use or where to start or how to flash back to stock to upgrade to MM if I don't end up liking the LP. I liked my S5 I just gave it to my mother though because I wanted the G4 for it's night camera mode since it didn't look like samsung was ever going to offer that feature on the S5 being as it still hasn't gotten the MM update.

Two different firmware versions. 11A and 13B. 13B being the latest LP version. Not sure if you can downgrade to 11A, but it is confirmed that you can downgrade to 13B.

Ah ok, I don't know how I didn't notice the 11a and 13b parts. Unfortunately after looking into it more I'm afraid I'd mess up my phone. I imagine I could downgrade to LP without a problem. But to accomplish what I want to do I'd then have to gain root which I don't know how to do on this one since the only video I can find of it relates to I think it was 10a. Then I'd have to install flashfire which I don't fully understand and then download the modified camera zip file and flash it using flashfire all just to get 60fps on the g4 which the g2 comes standard with lol. I wish there was one thread that covered it all walking down the list of to go back to LP do this, Followed by to root specifically the LP 13b vs986 do this. To install flashfire do this. To flash the moddified camera do this. That would be a long post. But I think it would be nice or even better a steady walk through video. If I had money to replace the phone I'd try all these things but I spent a pretty penny on this phone just a few days ago to get a good serial number that wasn't prone to the bootloop glitch the G4's had. $400 on ebay. Bought it new with the platic still on it and everthing still sealed. Just to get a S/N that started with 510

My battery life has been terrible since the MM update. I have factory reset twice and it hasn't helped at all. I used to get like 3 hours of screen time and have like 15-20% battery left after being off the charger like 18 hours. The phone generally performs better, but battery life has taken a hit. I haven't tried getting a new battery yet, but I generally alternate batteries daily.

I've noticed no difference with MM, compared to LP. Rather disappointing, but I've always kept my phone minimal so I guess Doze can't do anything more.

Battery Question

Guys,
i need some help. Over the last two days, my battery has just gone. The attached screenshots are from earlier this morning. I'm really not sure what's causing this. I lost 11% in under an hour and my phone was telling me it has 4 hours of battery left. I haven't installed anything new in the last two days.
I've tried using better battery stats in the past. I'm not sure how these apps work. I noticed my cell service isn't that good but I'm at home, always on WiFi. Can someone point me in the right direction? This phone is not even two months old.
Thanks in advance.

I highly advise you to turn aeroplane mode on and enable WiFi calling if you have it. It saves so much battery! This is whilst your indoors of course. Keep your brightness below 40, disables location when you don't need, disable auto update and sync behavours, disable NFC and Bluetooth if not being used. Disable animations via developer menu.

Your screenshots don't seem to show how much battery Android OS is using and there's nothing battery draining in what you did include, so I don't know that anyone can really do a lot to help you beyond offering very general suggestions.
What Rom or version of Android are you running? If you are running stock did a monthly OTA update install recently? It is that time of the month.
It's possible you have a rogue app but there's nothing showing up in your screenshots. It's possible that Google, Facebook or some other app is getting sync errors. Where you would check for that would depend on what OS you are running.
You could contact Pixel Support but my guess is that they would have you try a factory reset, which might be your best course of action based on the limited information you have provided.
My battery percentage currently shows 61% 1 day and 7 hours left, so you definitely have something wrong.
I would personally start with a factory reset. You could also run the phone in safe mode for a while and see if the problem persists. If it doesn't then the issue is likely a third party app.

When I had my battery issues, I factory reset and just ran stock for a couple days. It turned out I had to RMA it due to a bad battery. Phone was dying between 20-60%. I would barely get 1 hr SOT

Your screen was on for the majority of that time. And that 4 hours left means at the current rate you're going you'll only get another 4 hours. That is nothing more than an estimate and it will change all throughout the day based on you're use. Try letting you're battery drain all the way to zero 3 times. This should calibrate the battery. Try monitoring it after that.
And a side note. Use you're web browser for Facebook. The Facebook app has been a known battery destroyer forever.

I:m running Pure Nexus ROM with the Elemental kernel.
Thanks for all the responses everyone. I will try to drain my battery and see if that helps.

I had this problem. I went in and disabled all of my Google apps. I then went back and re updated them in the Play store After that I did a restart and I haven't had one since. I also recommend not having a battery case as both the Mophie and ZeroLemon both caused huge wakelocks for me. Cheers. ?

Nougat battery drain

Okay so, I flashed the latest Resurrection Remix yesterday, great performance ; however, there's a weird battery drain occurring to me. I've already tried multiple guides using greenify, amplify, etc but none really worked. I was using Viperrom 5.10 and wanted to revert back to complete stock after noticing random restarts and this battery drain. I installed stock through twrp with the backup I had before flashing and rooting then installed the stock recovery but still there was a battery drain. I flashed Leedroid, PureFusion 7.1.2 and still same problem. I think this is caused by something in Nougat since all the ROMs I flashed were nougat and showed the same issue. Now, I've seen many people experience the same problem but no one found a proper solution. Any insight as to whatever causes this battery drain would be appreciated. I'm not a heavy user at all; I don't have any games and all my apps are basically just social media like Telegram, Whatsapp, Youtube, Instagram and get barely 2.5hrs of SoT. Something to note too, my phone reports illogical battery percentages and sometimes shuts down when less than 50~40% due to an empty battery. For example, I restarted my phone a few minutes ago and upon booting it was 98% from full charge then I rebooted again and it's 78%.I'm not sure if this is a faulty battery or something wrong with the calibration. I tried calibrating multiple times but still nothing. I never abused my battery and most times I charged my phone before it hit 10-20%. Also one more question, I've noticed that on PureFusion the charging amperage was around 2-2.8 amps but on RR it reports 1.7 amps so is quick charge enabled on this ROM and if not what are the kernels I can flash to get QC? I've tried flashing Elemental X but it gets me stuck on the HTC splash screen.
I admit I'm kind of a noob when it comes to reporting bugs or issues, and I'm sorry for the length.
I'll add better screenshots of my stats after I collect more data.

I, and a lot of others, have suffered from the same symptoms. I thought I was alone but there is a big thread here https://forum.xda-developers.com/htc-10/help/random-shut-boot-loops-t3690547. I have got a support ticket (which is probably soon to expire, whoops!) but I've currently got it stuck in a bootloop at HTC (white) screen. Is this what yours did? Can you help me out?

No, my phone simply stays on the black screen with HTC logo in the center and the red text under it. Idk why it does that after flashing the kernel, probably not compatible idk,but what works with me is flashing the ROM again without messing with anything else.

Fixed mine, thanks. Just reflashed a stock rom I found on here. Wish I could help you more, but I think you might have to just return it unfortunately mate

I bought mine from another country and no international warranty so :/
I'd appreciate it if anyone replied to this thread. My phone is really unusable and disabling everything makes it useless and doesn't even save that much battery. My last resort would be to replace the battery but we all know how that would turn out and how it happens .
I tried :
1.Factory resets.
2.Flashed Viperrom,Leedroid,Purefusion 7.1.2,Resurrection Remix.
3.Flashed kernels like Cleanslate,Helix
4.Used battery saving apps like Greenify, Amplify, ForceDoze.
5.Disabled location, wifi, sync, cleared cache , reset app prefences, etc...
6.Started phone in safe mode.
Took all these steps and literally no significant improvement. I can't pinpoint an exact reason as to why I'm getting this drain but I noticed a lot of usage in GSam made by Android OS and in BBS and Wakelock detector PowerManagerService.Wakelocks seems to be on top of usage, and *launch* and *alarm* also have a very high number of wakelocks +1000 or even +10000. I've read on another thread that it might be wifi issue staying awake all the time. If someone has a good app to recommend me to monitor exactly and record whats draining I'll be eternally grateful .

Just a quick update.
I collected some stats. Not much but i saw some errors in there maybe some make some sense of them?
Mainly errors that are about Batterystats service: No controller energy info supplied and Power HAL : Failed to acquire lock whenever i touch the screen
I'll collect more logs and screenshots overnight in a +6hr period.

Hmm. That's weird because I had multiple ROMs installed and tested without any 3rd party apps like facebook and still get awful battery life. I'm back to stock now and will try deleting the fb app. Your stats are pretty good compared to mine.
Thanks.

You are welcome , i hope it work for you too , because i have noticed that Facebook application have too much irregular activities while the screen is off and when it is on there is a lot CPU usage, so it must be there something wrong

I found no solution except a battery replacement i can say it was definitely the battery. However, the drain is somewhat higher than it should be on Oreo.

Glad I sold my HTC 10 and bought XA2. Way, way better

Android 11 update - serious battery drain issue

Hello,
2 weeks after Android 11 update, my pixel 2 xl started to feel hot and the battery was discharging quickly. On Google help, many people were in my case, and many of them mentioned about unstalling Tunein. Which I did, then my phone stopped to be warm but this didn't stop the drain issue. What I have noticed is that if I don't touch my phone, the battery acts as normal, slow discharge, but when I use it, meaning when the screen is on, the battery just discharges at a crazy speed. It was not like that just before the Android 11 update. Anyone got this problem and found the reason / a fix ?
Thanks

I am having the same issue. An have not found a solution as of yet. I thought it may be the Pixel Launcher. So I changed it to Nova Launcher with no change.

Yes, strange. Mine gets a serious battery drain from 100% to 50% in a short time, even when I don't use it. Then below 50% it is very stable as long as I don't use it. Never experienced this before.

I have the same problem. before that, I was calmly getting 4-6h SOT After updating to Android 11 as lucky as I get 4h SOT. Mostly, however, I have 2.5-3.5 hours. The standby time seems ok, Only during use the battery disappears very fast. ? In my free time I will try the factory reset.

I think i got it...
Hello gentlemen, i got this problem with october update in particular.
So, digging in a google forum i found a user who recommended to install an updated version of Android System Webview (maybe you should download it from apkpure or apkmirror) , Carrier Services and.... uninstall Tune-in (yep... the radio app)
I don't know which one did the trick... but it just did..
I hope it helps!

Can you comment which versions of carrier services and webview you installed?

Sure, i installed webview 86.04240 and (there was a mistake in my prev post) Device Health Services 1.17.0.331553323.
Anyway, i got 2 webview updates since then... so, just install the last one... if you got auto-updates enable you should have your problem fixed by now (i guess that happened to the op).

thanks for the info, unfortunately I checked and I have exactly the same version of the application installed. the problem with the battery remains. the strangest thing is that I have no problem with idle drain, but when used with the screen on, the phone uses almost twice as much energy as before ?

I have the same problem, idle drain is ok, but whenever I use the phone, the battery drains very fast.

finally someone with the same problem. did you do factory reset before updating to Android 11? Because I don't, and I think I'll try to do it.

NO, i didn't do a factory reset because I have seen a lot of people (online) doing it without success. You can see this thread here on Google support, over than 580 comments today...https://support.google.com/pixelphone/thread/70445129?hl=en
But apparently some people fixed the problem with a factory reset...

I had the same problem and it was a new (at least to me) Google program called "Digital Wellbeing". I had to turn it off, which wasn't a straight forward proposition. I even "uninstalled" which just uninstalled the updates and they came back.
I don't recall exactly all the steps I took, but I now have my trusty Pixel 2 XL back to it's previous battery usage. Which is excellent for a three year old device.
Anyway, turn it off, take away all it's permissions, and do everything you can to shut it down. I was almost ready to root my device just to really get rid of it.

I disabled digital wellbeing, stopped the permissions, and uninstalled the update on the play store, but it didn't fix the battery drain...

A few days have passed and I can see a significant improvement. Honestly, I don't know what actually helped. some app update or maybe something I did, but there's a significant improvement.
In general, I would like to remind that from the update to android 11 my battery was tragic but only when using it, there was no problem with standby.
I was barely able to get 4 SOT hours. Now I can safely exceed 6 hours.
The only modifications I made were:
- leave beta program of digital welbing and its complete shutdown app
- disabled wifi scanning
- disabled Location service for emergency calls ELS
Since then, battery consumption with the screen on has dropped from 25-30%/ h to 12-16%/h. The phone is like new again. In addition, everything works very quickly and smoothly. ??
