[Q] Help With Battery Drain

In the past week or so, I've noticed that my battery is draining unusually fast. I will take the phone to bed with me (I use it as an alarm clock) at 100% battery and I can wake up 7 hours later with it at 82%. When I look at my battery information, I see steady, solid drain over that time, with the biggest offender being Google Services. When I look in Wakelock Detector, I see the most usage (though seemingly not a ton) by Android System.
I found some tips on using Wakelock Terminator in Xposed to filter some things from Google Play Services from triggering wakelock, and I was optimistic, but it didn't seem to help.
Any advice?

Are you on a stock rom? Did you try greenify? It's on the play store. It kills the apps background services and the app itself until you start the app or the app is started by another app or service. Soon as the app os no longer needed it is turn back off. This program does not freeze apps it prevents them from running until needed.

Ah, sorry, I should have mentioned my rom and such. I'm running ForceROM, a relatively older version (maybe 2.3?), since I never felt the need to update.
I haven't tried Greenify. Haven't actually heard of that one before. I'll give it a shot. Thanks for the tip.

Try a custom kernel like KToonsez in addition to Greenify. It's amazing what you can end up doing with that kernel

ForceROM includes Ktoonsez kernel. For the last 8 months or so, I've had great battery life. This is a sudden and recent change, which I'm assuming to be caused by an update of some Google app (such as Play Services).
How do I use Greenify? Or do I just install it and it does magic?

Do you have auto-sync enabled? What Google Services do you have enabled for sync? I used to have a similar issue but turning off sync for things I don't use (like newsstand, etc) helped my battery life a lot.

I believe that installing Greenify might have done it. Battery usage looks much better today. I'll do a real test tonight when I get it charged to 100% before bed.

Well, I'll be...
I think that the problem is wifi. When I'm at home, I'm on wifi, and the battery is constantly draining. When I'm not at home, and on mobile data, the battery is well-behaved.
What's up with that?

Are you using Google's keyboard?

Some apps can be setup to sync over WiFi only instead of 3G/4G data. but you have to check what apps would be the culprit. I know Google play, dropbox's picture upload feature can be set to download/upload/update over WiFi instead of data. But the only way to know is to see what apps connect over WiFi.
WiFi is suppose to give you better battery life since its signal is usually nearby and your phone doesn't have to use more power to find a better signal like it does with 3g/4g. I know for me it does since there are very few towers in the middle of the dessert.

No, I use Swiftkey.
So, interesting twist to this saga. Leaving wifi off takes away the solid blue bar on the battery screen, but I still see the same level of battery drain (about 18% overnight). Very intriguing.

Agreed

Agreed helps a lot when charging phone. May get a lil glitchy if you run it on every app.

Sounds like you're losing power to things syncing over wifi. Maybe try just giving it a week and watching it to see if it settles down. Google play sometimes settles down on its own. I also vote to check out greenify. With the donation package you can work wonders at calming down power hungry apps, even system apps.

My situation has suddenly taken a turn for the much worse. I don't know what's going on. I haven't added anything new or changed any settings since installing Greenify a while back. Now, the battery is just tanking. I got up to 100%, ran Battery Calibration and now, about 2.5 hours later, I'm at 82%. Could this just be a problem with the battery itself? Do I need to replace it?

Are you on MJA?

Honestly there are a few days where the battery life suddenly drops dramatically. I've experienced this on unrooted mf9, mk2, and nae. Give it some time and see if battery life comes back up. You can reboot the phone to kill a rouge app that might be the cause.

This is the first I've heard the term MJA, so I don't think I'm on that.
There definitely do seem to be days where battery is worse than others. And I do typically try to reboot when I see it acting too squirrelly. I'll just keep keeping an eye on it. Weird-ass phone...

Terrible after 23.0.1.A.5.77 Update

I have just bought Xperia Z3 Compact 6 - 7 days ago.
Battery time was more than perfect.
BUT my phone asked me to install 23.0.1.A.5.77 Update.
After update, battery life is very very bad now.
I did a factory reset, but nothing has changed.
Still the same update. Still terrible battery time.
Thanks

You didn't ask a question so I presume you'd like to revert this update...?
If so, grab FlashTool, install its drivers, and find an FTF of an older update, then flash it. It does not void your warranty and it does not harm your device.

Same problem here, specially when the screen is off.
Something is draining 15% of the juice per night.
- Stamina Mode on
- 3g on
- Whatsapp, Pushbullet and Timely in the "exclusion list"

I had similar issues. Also with tap2wake.
Solution: Reverted back to .98 with flashtool. Now its awesome again.

I had 0% drain overnight last night with this update

If you mean Diagnostics under 'About phone'. I went through all the tests, nothing crashes on mine? Or do do mean elsewhere?

Yes, I meant that, and then the second option "phone characteristic" or something like that, then you see how many times the phone crashed and what processes are involved

I too am having terriblr battery drain after updating to 23.0.1.A.5.77, I've tried everything; Factory Reset, Flashing back to previous builds. All to no avail.
I've installed Gsam Battery monitor and it tells me that 'Android System' is constantly draining and is at the top of the list.......
I really dont know what to do.

haven't noticed anything different really after the update. the battery life seems the same

I noticed battery drains on my Z3 after the .77 update so I did a clean reflash and after letting it settle in for a few days the battery is back to performing awesomely

I heard such battery issues and still went ahead to see does it really hungers your phone so did the update and I hardly notice any unusual battery drain.
My screen shows 45-61% battery usage and rest all fine. Dont know how to reduce that but its ok.
I get 2 1/2 days battery easily without any stamina mode activated so I guess it pretty awesome. :fingers-crossed::good:

Hi, I did not find a battery drain on my z3c but did find out something on my prev. phone, the z2, my phone went battery hungry after flashing update so I gave it 2 days to settle. The drain kept, driving me nuts. I than did a full wipe didnt help. After formating the sdcard away was the battery drain! Probably some corrupted file or sector on the SD kept the phone draining the batt.
Also seen on other phones that some malfunctioning simcard could disrupt the stability and power usage. Some operators use cheap cards that can just die on there own.

Battery drain problems with my Verizon galaxy s7 edge

So I recently bought an s7 edge from Verizon and it has horrible battery life compared to other people with the same phone. I went to Verizon with this issue and all they did was give me another phone in exchange for the previous one but that did not help. Sometimes the battery drops 12 percent on standby overnight. I have found a few apps which have been draining my battery but I unfortunately cannot disable them: gear vr service, help, and knox use over 12 percent of battery each. I wish I could root the phone but no roots are out for the snapdragon version. Help would be greatly appreciated.

Can't you just use disabler pro to disable those apps

Im really amazed how people just go to lets say phone provider and say that they dont like the phone and they get a new one . In Poland I think this kind of thing just wouldnt work. Especially that at the moment this phone is sold out and i was luck to get mine so fast.

I don't think using location is what is causing my battery drain because like I stated before my friend also has the same phone but on a different carrier and even with heavy usage his phone battery life is amazing. But I will see which apps do use location a lot.

Yah I saw it before

Do you have AOD on at night? That will burn through some battery.
Those three apps are interesting. How did you determine they're using a lot of battery?
When I look at them in the application manager each one says it's used 17% of battery since the phone was fully charged (24 hours ago). But that can't be accurate. Added together, they'd use more than 50% of my battery capacity, but they don't show up as individual apps in my battery stats, and the largest user (Android System) only used 30%.
Can you post some screen captures of the battery usage screen showing the apps using data? You might also try force charging to 100%, then force closing those apps, and see if there's any impact on battery life. If not, then it might be worth trying Package Disabler Pro. But most Edge owners seem to be getting good battery life, so I don't think that should be necessary.

I am getting the same drain (S7 edge verizon). It only drains my battery at my dorm wifi and when I go home it's fine. I don't think it's a Samsung issue since my LG G3 with a 6500mah battery can't even last two days on standby.

Average SOT for One Plus 5 Users / Mobile Radio Active Bug still present?

Hey Everyone,
Can someone please tell me what's draining my battery? I used 32% of battery and didnt even get 2 hours of SOT. I do see that my connection is bad.. (at work right now on the 11th FL). I did turn on airplane mode but it seems like the mobile radio wont turn off? Anyone else facing the same issues?
Currently on stock OOS 4.5.14 Kernel- Simplegx Kernel

I don't know. I'm on stock 4.5.14 and stock kernel. I am getting about 9-12 hours of SOT and .3-.6% idle drain for a combined drain average of about 2.2-4.5% an hour depending on medium to heavy use. I don't do anything to crazy with my setup. I just turn off my google account sync unless i add a contact or something then i manually sync them, turn off background data for each app that has no need for background data usage. Work email is on push and personal email is set to fetch every 3 hours.

Seems you're not alone, my 4G+ isnt' great, never seems to connect in the same places my old phone did, and even when it does its nowhere near as fast.
Data is sub-par compared to other devices, it's that simple i've been through every single setting, nothing can change it.

I don't know ow either. I have my OnePlus 5 since a few weeks ago and so far its battery is showing being the best I've ever used till now (I upgraded from a G4+).
I usually get 7-8 hours of SoT with medium usage:
- WhatsApp
- Phoenix (Facebook/Messenger)
- YouTube
- Some gaming (Free Fire Battlegrounds)
- WiFi + 4G+ (switching between them depending on where I am).
I leave home early on morning with full charge and get back with about 30% left.
About the 4G+, it's showing really good here, nothing to complain about it.

Are you sure? How do you know? Could that be the settings Mobile Data always on? Or maybe allowing google to scan for networks, allowing apps to use data without permission? Not 100% if it's the phone.

Exynos LTE battery performance (Battery Historian)

Aware of the current discussion around the LTE drain issues with the Exynos version of the phone. Yesterday I did a full 24 hours off charge on exclusively mobile data and lost around 65% for 80 minutes SOT.
Before taking it back to Samsung I wanted to confirm that there wasn't anything else causing the drain . I'm no expert with battery historian but I can't highlight the causes beyond the following:
Screen off uptime: 3hrs 27 mins
Kernel Wakelocks: 5hrs 32 mins
CPU Usage: 2:32 of user time vs 5:14 of 'system time'
Kernel Overhead 1:45
"999:MAILBOX_CP2AP" - I suspect this is linked to outlook but can't be sure, causing 150 wakelocks an hour
"Abort:Some devices failed to suspend, or early wake event detected" - No idea what this is
Would anyone be able to provide any more information or assistance in analysing the chart?
Thanks in advance

Try to change outlook. My experience is that outlook was making battery drain crazy, remove it and got other phone.

Haven't and wont have an opportunity to do a fresh install for a while, need to do a day on wifi to compare the results.
I did spend a bit of time on wifi and adaptive power saving and it all but wiped out the "999" wakelock (I think this is because the system more aggressively bins the wakelocks "
Will also try safe mode/ removing outlook to see what happens

I'm having the exactly same issue of yours! 999:MAILBOX_CP2AP is appearing crazily! Do you found any solution yet? My phone don't have outlook installed, but the wakelock still going on crazily.. It seems only appearing actively during mobile data is turned on.

What outlook are you using? Is this the outlook from the play store or is it corporate setup outlook mail using some sort of exchange servers for synching?
I have since my note 9 disabled the stock Samsung email app and use only outlook. Since the stock email app for me was causing drain.

Strange. That's the only app I use for multiple email accounts that seems to be less resource hungry. I still have gmail all though.

I deleted outlook and the wakelock persisted, so it's not that, but I don't have another mail app so very confused.
The 999:mailbox wakelock still appears when on wifi but its negligible compared to when on LTE

Googling that process didnt yield much success.
I use accubattery pro and gsam. I tried to locate and install battery historian but couldn't find it. Maybe its for exynos only that app?

Unfortunately GSam and better battery stats currently don't work on exynos, I have accubattery but it doesn't offer much beyond basic battery stats
Battery historian uses the bug report that you can produce in developer options

Hmm I tried safe mode, even hard reset OS by sending to service center for them to do that for me, still same.
Although my battery life doesn't consider that awful but not satisfying. I started to doubt whether it's some hardware related issue.

And the wakelock persisted throughout? It might be nothing but the only difference I can see between wifi vs LTE
It's so good for battery on wifi but middling when on mobile data

Over a 50% battery usage period I get approx one or so less hours sot using LTE. If that makes sense. View attachment 4768566View attachment 4768567

I'm Exynos, dual SIM, I am an area manager and phone is my main work tool doing audits on them all say. Both Sims work overtime as I'm mobile all day in remote areas, the screen is an auto as I work outside and need full brightness and I use WQHD. Only thing i turn off is aod and I've done the stuff in the battery optimisation thread
I charge in the evening and get 24 hours on the battery , average is 7 hrs sot and 2 hours talk time
This is perfect for me

Did you play around with your settings?
