[Q] Battery drain problem - Asus Eee Pad Transformer Prime

Hi,
I have a problem. My Prime doesnt show which apps drain the battery most (in settings). It says that the data about consumption are not known I dont know where is the problem. So I wanted to ask if there are any apps which shows me the other apps and how much they consume. Thanks!

[Q] High battery drain on stand by when wifi is on

Well, that's the problem, I'm having a very high battery drain on stand by when wifi is on and don't know how to solve it. I've tried a lot of roms and I have the same problem (only Omega didn't have this problem for me, consume was normal). The drain is about 5 or 6% per hour, while just lose 1% per hour with 3G/ HSDPA. It's really strange.
Sorry if it's been commented, I searched in the forum but didn't find anything.
I'd really thank any help, as it is very annoying. I post here a screenshot of a night time with wifi on.
Are you sure you don't have any background apps running from the wifi or any widgets that stay constantly connected to the internet? Seems to me as if this is not a problem with the wifi but with apps.
long press the middle button until the open apps pop up and press the trash can. See how this affects the battery life.

I have just made a clean installation (wiped everything) and I'm going to leave wifi on tonight without any application installed (except system apps), so let's see if that's the problem.
Thank you very much for your answer

Autosync ..

Hi everyone, does auto-sync drain battery ? Somewhere i read yes, some other place i read no ..
People telling yes says : It's always keeping a connection with google so draining battery..
Peple telling no says: It's when the app demand that it's sync background .. so no battery drain..
So what's the real answer to this ? Does it drain or not ?
When an app syncs, it needs to connect to the internet, so that uses battery. Also when it syncs in the background. However it is not continiuously connected, so it will not drain your battery at once.
You can change your settings to a lower frequency (e.g. sync only every hour)

[Q] Battery drain

until a few days ago i was getting decent battery life but now battery easily drops around 40 percent overnight without any usage.. when i checked battery usage (I'm on IC) android system and google services had 21% each.. when i try to use amplify/unbounce from xposed, phone lags and random reboots and greenify doesn't help that much either...
is there something i can do?
Maybe you can try disable service and appopsxposed

Try disabling google now, turn off location, wipe cache and dalvik and check if the issue still persists. If yes, try downgrading google play services.
The best way to figure out battery drain is to install either better battery stats or wakelock detector and see which services/apps cause the drainage. I specifically stopped using and uninstalled google now (as much as I like it) and keep location tracking/gps off until I need it because of this very reason. Add in greenify and results are huge improvement in battery. Phones are useless if you don't have battery for its main purpose, phones calls and internet usage.

First of all, turning of location services and Google Now solved the problem for me. From now on I only turn on location services when I really need it (for example Google Maps)
Now another thing you could try is this app: https://play.google.com/store/apps/details?id=com.playfulgeeks.gservicefix
Seems to have fixed the problem for many (check the reviews)

Apps Responsible For Battery Drain

After having run 'Better Battery Stats' for several days and after several recharges, these were the following apps causing battery drain. This includes partial wakeups, Alarms, network use and processes.
The top apps for biggest battery loss were:
Whatsapp
Beautiful Widgets
Firefox
Swiftkey Keyboard
Gmail
Life 360
Other apps causing slight to moderate battery drain:
Google Play Store/Services
Album
Battery Doctor
Devices
DS Battery Saver
Handset SMS
Power Amp
Surf Easy
Talkray
Despite force closing the apps, they keep re-opening even though the internet is not running and the phone is supposed to be asleep...
Greenify is even running 24/7 but doesn't seem to help with the above apps. Hibernating all the above apps seem to make little to no difference and high battery usage is still an issue...
On screen time is just 2 hours 36 minutes and battery is at 23% and draining very fast with no use at all.
Any other way to stop the above apps from draining so much battery?
I've tried many different roms, kernals and apps but battery drain is an issue regardless...
Just come back from lunch. Battery is now 17%
Why has it dropped from 23% to 17% over a 2 hour period? The phone has not even been touched since I left it in the office...
Is it possible I have a defective battery or would it be due to bad apps?

Hi.
I'm using Stock ROM (4.4.4). I have more than a hundred of apps installed and my battery time is more than 5 hours with heavy use (screen on). I can't even imagine how many days the battery could work with the screen off.
Is the weak battery mode activated? Is Stamina on? Have you checked your battery details on the config panel? And what about the internet use? Is auto-synch off or at least are you scheduling when the apps can download background data? What about the system statistics about background data?
Are the GPS and bluetooth off when you're not using them? Please also remember wifi use way less battery than other mobile connections; that battery goes away faster with more brightness on the screen; and that you can get some more minutes if you let the auto-rotate off.
Have you checked if some app is preventing the "deep sleep" state?
If I was on your shoes, I'd uninstall all the 3rd-party battery utilities (even Greenify!) and I'd restart my Z Ultra.
^ Thanks for the reply Andre Verissimo. I too have 4.4.4 stock rom and only around 25 apps installed...
Stamina mode (power saving mode) is on 24/7 and brightness is set to around 50%.
I never use GPS/Satellite, bluetooth or data/mobile connection...
Auto sync and backround data are disabled...
I did track apps causing high usage. They were whatsApp, Firefox, Google Play, Battery Doctor & DS Battery Saver.
I'll try uninstalling several apps and see if it helps...
Seems I finally solved the battery leak issue.
I prevented bad apps from auto starting as well as to close once the phone has been put to sleep.
In other words, the battery will only be drained when in use. However, the phone appears to be in deep sleep since I manually set 'Battery Doctor' to kill/close apps when not in use as well as stop them from auto starting...
Only the battery draining apps have been selected to do so...
My phone has been on for 24 hours hours and my battery is still 85%
I will monitor battery usage over the next couple of days and report back with any update.
Regarding Beautiful Widgets: Are you talking about the free version or the paid one?
I am on the paid one (Pro) and it shows up as 0.3% on GSAM Battery Monitor. If you have experienced drain on that version, I will look for a different clock widget then (i.e. that it actually drains noticeably but in such a way that it doesn't show up as such).
I have the impression that the free version of Beautiful Widgets could be a drainer since it seems to be very happy to push a lot of ads and stuff.
Will try Battery Doctor and compare with Greenify.
Edit: I think Greenify is working properly on my device, i.e. it hibernates the apps properly.
your network signal greatly affects your battery and that will not show up on your battery usage stats

I'm on the paid version of Beautiful Widgets. The app has only affected my Processes. Usage is 9% . However, there are no alarms or wakeups from the app since I disabled them both using per app hacking...
I will search for an alternative to Greenify to hibernate apps. Only 3-4 apps are opening despite force closing and even preventing startup, alarms and wakeups...
Regardless of what I do, the following apps continue to run and launch even when not opened:
Photo Analyzer software
Mirror Link System
Devices
WhatsApp
Xperia extension for throw
Sweep Panorama
Creative effects
Camera
Albums
Screen Mirroring
How can I prevent the above apps from automatically launching and running? I blocked all listed programs from launching using both Battery Doctor & per app hacking yet they still re-open and run...

Very true. Where I work, reception is VERY poor since I'm in a large factory high up...

Battery drain ONLY when smartwatch is NOT connected

I tested this with different watches and different apps and the result is always the same - there are almost constant Bluetooth wakelocks (BetterBatteryStats reports over 50%) and hence battery drain - but only when the watches are NOT connected. When the watches are connected - everything is fine!
I am running rooted Android 10 and tried to manually put the smartwatch apps in the Sleeping apps and Deep sleeping apps (Device care > Battery > App power management) but the result was absolutely the same. Only when I uninstall the apps, the Bluetooth wakelocks and battery drain stop.
This is driving me mad because I have to keep the watched turned on at all times, because otherwise will face battery drain. Has anyone had the same problem? Any idea of how to solve it will be much appreciated.
Can you not simply set it to go to sleep when not in use? (Through >device manager >battery)
I know it's possible because I had the same problem with my girls phone a while back, just can't remember how exactly I fixed it, but it turned out to be pretty simple...
Thank you but I did this as I have described and it desn't help.
