Help with solving battery drain on SM-T500 WIFI model - Samsung Galaxy Tab A series Questions & Answers

My husband got a Tab A 10.1 last year for Christmas and uses it mainly for streaming music on YouTube and surfing marketplace on Facebook. While I know both apps are battery hogs, the battery drain is still unreal. Just having the tablet on the "home" screen for 5 mins will drain the battery 14%.
I have either removed or disabled all the apps not needed, have optimization setting set (says battery life is over a day haha), brightness is low and on auto, and also have an auto app kill installed to stop apps in background. Have gone through and removed background permission and set allowed open background to only 2.
Short of rooting, which I prefer to not do with the lack of options, is there anything else that I can do here? Is this a common issue with this tablet?

If you are having that kind of battery drain just on Home screen, without the music or facebook apps running, either the battery is bad or you have some kind of malware. Have you tried factory reseting the tablet? Or running malware detection app?

I have run the built in tablet scan for virus and malware threats but have not installed an independent app. I will try that though and see what happens. I will also look and see if this tablet is still not under warranty, but honestly just going a phone repair to have battery replaced might be cheaper and faster than sending back to Samsung. Thanks for the help.

[Q] (Q) Why is my xperia play "awake" when the screen is turned off ?

Hey forum ! , I was an iphone 3gs user and made the jump to android when the play came out.
Ive noticed my battery is draining 2-3% an hour and looking at the "battery use in setting and then looking at the graph it show the phone is randomly awake even when the screen is off.
My play is rooted using gingerbreak 1.1 and has mostly all the bloatware removed.
non of the apps i have installed ask for permissions to prevent standby, I only have tune in radio, mobo player, facebook, twitter adobe pdf viewer, fpse, snesoid, gameboid google maps youtube imdb touch calendar es file explorer unit convertor and ringdroid installed.
i have 12 processes running using 86mb of ram
all apps are closed properly, wifi is off, background data is enabled ( but no applications i use in the settings allow auto refreshing of data)
The battery life of my xperia play has never been great (lasts about 24hrs with just checking facebook, twitter and xda forums using the built in browser)
I just wonder what is causing the phone to keep waking up randomly, is this the culprit of the battery drain?
I have a couple of theorys .... i did install desktop visualiser to change the icons then once they were changed i deleted the app (i read this app causes battery drain) maybe this could be a cause i thought deleting the app would fix,
2nd i travel around as part of my job so i wonder if the phone is going through areas where there is poor connectivity and its constantly trying to connect to different networks causing the drain.... but does anyone know of any efficient lightweight apps that disable this when the screen is off.
lastly I think the could it be widgets i only use the built in ones with the phone, the wifi on/off gps on/off and data on/off
do you guys turn data off during the day to save battery and do you turn background data off ? i think its anoying have to change all these settings off to sqeeze a tiny bit more of juice out the phone, it probably uses more turning them on and off avery 1hr or so
any suggestions or setups of how other people have got there phone up and running with good battery life would be a real help
cheers !
Deleting all widgets certainly saved my some battery, also deleting the SE launcher with launcher pro seemed to save me a lot of battery but I'm not sure about this.
2 to 3% an hour isn't bad with radios on at all. When you say awake, do you mean the screen is on, or that it's just in standby? There is nothing in battery stats that say "awake" you need to be more specific on what the system says, not what you think it's doing.
If the screen is coming on "randomly" then it could be an incoming txt, email, phonecall or something like that. Lower your screen timeout in the settings to help there.
If its phone idle or standby, then again 2 to 3% is nothing. That's 30 50 hours of standby receiving emails, txts and what not. Nothing to complain there.

reboot fixed my stay awake problem
by stay awake he means no lockscreen/passcode/slide to unlock

Click on settings then about phone then battery use then at the top of that screen there should be a set of numbers saying how long the battery has been used since the last charge, click that an it displays a graph , on the graph page it shows when the phone is "awake" by awake I mean the screen is off the phone should be in standby mode but its being acessed by something i.e a program , like its woken up to perform some action. Anyway im wondering if anyone elses phone is awake randomly when the screen in off and in standby mode. When I factory reset I neget had this issue but its after installing apps I think or some setting im missing any ideas
I have the same problem. My Xperia Arc is "awake" all the time. Screen is locked, turned off but in battery usage I see that the phone is awake even with screen off. The culprit seems to be the native messaging app as it consumes the most battery. I'm not sure what is going on, what is the messaging app doing or which process is using it.
Any ideas anyone?

Google Services/Google Play Service/Google Framework Services draining battery

Bear with me. If you are an expert on android maybe you can help me out here. First off, I have researched the crap out of this problem and still been unable to fix it, so YES, I did search before making this thread.
I am on a stock, rooted Verizon Galaxy S4. I have been watching my battery consumption carefully via the integrated battery settings menu, battery stats plus and wakelock detector apps. Mainly, there is a program or set of programs that typically is called "Google Services" that according to the integrated battery menu is consuming anywhere between 20-45% of my battery, sometimes more than the screen on time! My battery life is around 48hrs with 10hrs screen time but that is on the massive zerolemon 7500mah battery which I just bought, so I am not sure if that is above, below or just average (i.e. I have no real standard by which to judge).
Like I said I have read probably every thread about this problem with remedies such as; disable location, turn off google now, turn off google maps reporting, uninstall updates for google play/google play services/google framework settings, turn off google sync etc. I have tried them ALL, none seem to work. I have a feeling the issue is perhaps more in depth and above my head.
It gets more complicated. Although the stock android integrated battery menu reports it as using a massive amount of battery, the other two apps I mentioned above do not even report it, or at least not under a name that I regonize (perhaps that categorize it under a different process?). Under them screen time is by far the highest consumer.
So what to make of this? Is it a false report that the stock integrated android battery menu is reporting, and thus something to disregard? I doubt that because there are many other threads out there of people with the same problem and questions I have. But It's also not like my battery drains within hours. For instance, today I have been off the charge for 12.5hrs, with 3hrs and 40min of screen time and have 63% remaining on the 7500mah zerolemon extended battery.
If you can help, please do. If this is indeed a major drain I would really like to fix it.

Yes that seems to work, but it's not really a "fix" as now I cannot use the location feature of many of my apps. Basically traded one problem for another, albeit lesser one.
I'm still trying to figure it out as since last update (MEA firmware) , my phone is heating a lot.
I had this problem with data connection on, I had this problem in airplane mode, but not strangely with having connection to wifi.
I also observed that google services and android system is consuming most of the battery. earlier when I used to get 8-10% consumption in full use in an hour, now, 8-10 % is consumed within 30 mins.
No tweaks are working. Frozen a bunch of apps but the problem is still there.
Just now I've uninstalled fileexpert HD , as "greenify" told me that since last 20 minutes my phone is on, it has taken 250+ wake locks.
I'm charging my battery to full to check if that solves my problem.
will try to disable location services and report back on the results.
Bump
Have the exact same problem, before the latest firmware my phone had awesome battery life, and now the battery goes from 40% to zero in just a few hours without any app running when I'm sleeping... it's horrible. Same problem with my wife's S4 since the latest update... It absolutely sucks.

Lollipop battery drain

I got the German 5.0.1
IS it only me or is it general with the battery drain?
Even in Flight Mode, I am losing the battery in a couple of hours

Hello everyone, two days ago i downgrade to kitkat, I decide to re-put Lollipop because I'm documenting on various forums Italian and foreign, and this drain the battery does not have all .... well for my case I installed the GSAM Battery Monitor from Play Store that seems to work well with Lollipop. I left the phone idle and discovered that the deep sleep has never been reached. The phone was always active, even when locked.
GSAM has reported that the app "Unified Daemon (EUR)" was among the top three applications that consume battery.
According to various forums is a preloaded application from Samsung that unifies information like weather across other applications preloaded. I really do not know what good has this application.
I tried to turn it off, and in fact the phone goes into deep sleep with consequent consumption "standard" like KitKat.
The downside of disabling this app is that you lose the weather from the lock screen and through the window of the cover S-view, while the widget on the home seems to work perfectly.
Obviously there is to say that others should do the same test and see if this app will appear among the first applications to battery consumption.
A greeting
disable Facebook app (use web version) and turn off wifi when not being used. My battery usage has transformed! See other thread....70% after 10 hours. 56% after 13 hrs! Lollipop is buggy. Manage wifi manually and you're battery will be awesome.

^^^^this^^^^ . Me too. Disabled damn Facebook and it a few Google apps and I'm back to normal. The main culprit is the stupid Facebook. To make easy access of it from Web just make a shortcut on your desktop.
I will leave wifi on today regardless of whether or not it is connected and see if things get warm / battery usage ramps up. If it doesn't it might indicate an issue with FB alone or at least prove whether or not wifi is stopping the phone from going into deep sleep after a period of non use. Yesterday having left FB and wifi off, resulted in 40% battery remaining after 16 hrs usage. It never got hot once. This is my yard stick.
Lots of users are having issues with the latest update to facebook - just look at the comments on the play store!
Anyone else been having high battery usage but are not users of FB app on lollipop?

@gasland Here is what i did.
I uninstalled
Facebook, Facebook pages, Facebook messenger and com.facebok."something"....
I removed everything that had the name "facebook" and rebooted my device.
Battery has been okay since then.
Ps: I also froze "unified demon" as I don't use either of the weather services or finances or all that crap.

Package disablers?

It seems package disablers are pretty popular now for helping you disable some apps that you wouldnt otherwise be able to disable. It seems alot of peoples reasoning for disabling apps is to save battery but iam wondering how much battery is the package disabler app itself using? After all. Its constantly running in the back working to keep those apps from waking right??
First of all, once you disable the app, it is disabled forever, no need for PD. As far as how much saving you get? 3 nights ago charged phone 100% before sleep, wake up 98%, 2 nights ago charged 100% before sleep, wake up 80% left. That would be x10 higher power usage . I went to app manager and force stop about 5 apps and everything went back to normal. Some apps can be brutal on battery (not sure if by design or it crashed) and all those people complaining about poor battery, it's not the phone, it's some programs running in background. For example If I don't even have facebook account, why is facebook running on my phone? If you know what you're doing you could easily double battery life.
Iam not fully understanding your reply! Are you saying package disabler is the reason your battery life improved?

I bought but haven't really touched Package Disabler Pro.
I think its better to have 1 app controlling/blocking multiple things than having multiple apps running multiple things and wasting battery.

I run package disabler pro and it shows as 0% battery usage with 37% battery left. I don't think the app runs in the background, it just force closes the apps that you select and disables them from running, so I think it helps your battery seeing it stops other apps from using your battery.
Is there any apps in particular recommended to disable besides the obvious? When i view the list of files within package disabler. It shows some items using ram but most of them seem to have no affect on battery life and aren't intrusive in anyway so i imagine it's just not necessary to disable them. I mainly wanted to disable Knox and bixby but bixby doesn't seem to be using any battery so again, iam not sure i need to disable it.
To make quick points in simplest way:
1. For best performance, only programs that you actually use should be running on your phone.
2. Package disabler is the program to use for system files, especially now, since we have no root yet.
As far as looking at the battery statistics, they are not very reliable IMO: I had my phone discharging 2% overnight and at other time 20%, when I looked at settings/battery/battery usage they looked almost the same in both cases: Android OS, Android System, Device Idle etc. no smoking gun and yet the phone was using battery x10 more. I do not know what caused this excessive usage, but I went to APP manager and manually force stop every non system application and all went back to normal. This is not the first time this happened to me and IMO simplest solution is not to have unnecessary software running on my phone, less chance for the programs to go haywire.

Battery drain anyone ? Oxygen 11 OnePlus 8 Pro

After upgrading to Oxygen 11 i do feel there's battery drain.
Tried to factory reset + Cache Wipe but still same.
Put display on 60Hz & FHD+ but no go..

what are the top drainers when you go to :
1) settings
2) battery
3) press on the ellipse ( three vertical dots ) in the upper right corner and choose 'battery usage'.
. . . for me, my largest app usage is aodNodify at a whopping 20 percent, followed by messages.
4) press on the ellipse again and choose 'Show full device usage'.
. . . for me it's Screen at 20 percent, and then Wi-Fi at 11 percent.

I get 10 hours with 120hz and FHD so no need to disable that.
Tbh besides what @old_fart said the main killers are
5G
Facebook
Not wiping after a major system upgrade ie; 10 to 11
Poor kernel
Misbehaving Google play services
AOD (looks great, kills battery)
Charging overnight (eventually this will murder your battery)
Gaming
Video calling
Misbehaving rogue app.
Misbehaving launcher.
Ads ( block them all)
You get the picture, I've compiled a large list of problems and suggested alternatives in the review section of this forum, can't remember which one but a lot of good tips are in there, give them a look.
Attached Battery status.
The Os was cleaned after the upgrade to Os 11.
AOD - is switched off.
5G - Not working anyway.. disabled.

Good to all that.
Are you on stock OS or any kernels installed? Magisk ROMs?
It's possible if your phones just been set up that it may be backing up/ syncing Google photos.
Go through your apps and make sure that there set up optimise instead of intelligent control.
Facebook is always a killer, maybe use the browser version it's not much different, personally I'd delete the account and every bit of info in it, hate Facebook
I would say OOS11 drains more battery than OOS10. I game a lot and my battery lasted longer on OOS10.

Depends on the game for me.
Emulation is a good test and it runs about the same for me.
I have tweaked my CPU thresholds though.
So there is no difference in up or down actions or peak speeds, all of which i reduce
Im using stock rom my SOT is about 5-6hrs tops and i keep seeing people with 10+ SOT with stock rom..

Stock mate.
I've used some magisk ROMs then I realised I can actually make the changes I want to myself.
I've used CRDroid and PE but I missed the OOS camera, battery was very similar to what i have in OOS but gaming does burn the candle a lot faster
Here's that list I made in the standby drain the in the review section, I made it a while back so some may no longer apply
"Change 5G to 4G
Remove Facebook use web based
Remove Facebook messenger use web based
Remove Twitter use web based
Remove any ad based apps pay for the pro version
Turn off gestures like lift to wake
Change from QHD to FHD (No difference)
Allow auto brightness
Turn off WiFi overnight
Turn all updates to manual not auto (play store)
Remove any so you don't use
Change back up to once a month (WhatsApp)
Turn off location history (Google)
Use titanium to remove any system apps you don't need
Don't allow anonymous usage statistics for any app ever.
Don't allow tracking cookies on any website
Use adaway (root needed)
Don't open web pages in Google app (I use Samsung browser)
Don't use xposed.
If you game you will not get high SOT scores, period.
Don't bother with battery saving apps or monitoring apps.
Streamline your apps, if you don't use it, remove it.
Don't allow WiFi scanning (as in letting other apps use it when it's not on)
Never allow personalised ads.
Never allow notifications from websites
Always decline cookies unless your absolutely have to allow some tracking (common sense prevails here)
Optimise as many apps as possible unless it affects performance.
Don't allow apps to remain open in the notification area.
Change your launcher, my preferred launcher is lawn chair and this did actually burn up some battery when compared to the OnePlus launcher.
Don't use live widgets (yes they look cool, but they annihilate your battery)
Live wallpaper, again very cool, but battery burners.
Again! Don't charge overnight, make a note of your percentage then see what it is in the morning, you shouldn't be losing more than 5% really, if you've done well then it'll be reflected here, the good SOT results will follow.
Turn off live read outs of network speed, RAM usage in the status bar.
Turn off NFC unless in use.
Leave location on in quick settings.
Don't overcharge your phone, IE: overnight
Don't allow your phone to fully deplete the battery.
Whatever anyone says, this does 100% damage batteries, there is no argument here and I won't entertain anyone who says otherwise, Ive seen through real life tests what this results in, bloated, inefficient, possibly dangerous lithium batteries.
Keep your phone out the sun.
Keep it out of extreme cold.
Keep your device clean dust free.
Snapchat, Viber, house party, apps like that tends to use more battery as they don't have great dormancy periods.
Apps like speed test by Ookla tend to have location tracking, similarly they tend to turn themselves on and off when they feel like it, my advice, install test and uninstall.
Allow a couple of battery cycles between tweaking sets, to give you an idea of how much of a difference you've made.
Use BBS to see what is being used, once you've removed problems, remove BBS.
I've just written this from the top of my head so o probably missed some things, the general idea is to keep your device clean and fresh, remove files you don't need any more.
Keep an eye on apps that misbehave or aren't wanted, index your folders so they aren't a mess
The more good things you do means the more potentially bad apps you can have on your phone, eg if you really need Facebook, you could keep it so long as you clean up other areas of your phone"
Good luck
Based on some years of experience i would add to this amazing and great list:
- Only use either wi-fi or 3g/4G/5g at a time. Alternate between them. ( ex. leave home - off wifi - on 4G, arrive home - off 4G - on Wi-Fi ) Don't use both on all day long. Battery will drain.
- Use sync off ( Playstore (mentioned above) and "sync app data" ). Only turn on when you want the phone to update and shut if off after.
Disabled some weird facebook management apps and it looks a bit better, currently 25hr's with no charge, 68% battery left and 1:48hr's of SOT.
Will test it for few days and update.
Not the most apps used today but still heading for 10 hours.
Lot of painful lost bets today.
Well, my battery now lasts longer on idle, but SOT while using it is still 6hrs
Some other guys from Facebook groups shows about 10hr's of SOT with QHD + 120HZ..
