and i charged my phone to 100% and the bank at 1|00% (4leds on) and attach it ot my phone and poweroff bank (phone battery will be used first) and leave my phone on bed.
after 15 mins i turn on screen to check if i got any whatsapp message and i noticed my phone with 89% battery and i was like WTF never happened.
i think is the power bank draining my battery but i dont know how, can anyone help me or explain what is happening,

Might not be your power bank, try using BBS to find out

After a day i can confirm is NOT the power bank. since this happened in the past 3 days
i used Airplane mode all the night to see if some a is Wakelock my phone and got just 3 % of battery usage with the power bank attached, so i manage another test since BBS told me is Android System RIL or something like that.
Second Test: Disabled 3G+ Connectivity for 2 hours and enable just GSM 2G and just got 4 % dropped ( i make a few calls and used whatsapp so is OK), i think is 3G becuase where ilive is outside the city and recently we got a heavy storms (causing shoutdown of the nearest anntena) i have low reception rnothing and 3g running so i think my phone is using more battery trying to acquire more signal and 3G support.

Battery Drains faster when in Airplane Mode.

Hi guys
So for some reason on my rooted Samsung Galaxy the battery drains quicker when listening to music in Airplane on than with a cellular and data connection :/ any ideas why? Background processes running and trying to access the internet or something?
Any advice would be great. This is really irritating as from 7 AM to Noon only listening to music my Battery life goes from 100% to 50-60%. :banghead: Thanks all!

My first guess would be that your music player is trying to use network services to get more stuff, and the phone is searching for the connection that is unavailable due to airplane mode.

Have you looked at the battery consumption to see what it's reporting as the power draw?
Settings -> System -> Battery
For example, mine shows Rocket Player #1 at 25% and Android OS as #2 at 15%, but that's after listening to music over bluetooth off and on from 7am to 2pm. Currently with 78% charge remaining.
Then click on the graph and you can see the battery 'curve' and the small dot graphs below showing Mobile network signal/location on/awake/screen on/charging.
In your case I'd be real interested in those graphs - see if there's anything forcing wifi/location/mobile network on when they should not be, also see how much 'on' time there is.
If that doesn't help you may need a more intrusive inspector like GSam or BetterBatteryStats or Wakelock Detector.

Go into Wi-Fi settings, 3 dots up top, advanced, turn off always allow scanning. That may be some sort of wake lock also.

[Q] Battery drain on unrooted phone

My MotoG 2014 with Lollipop 5.0.2 is unrooted, I have read other threads about this problem: I've installed Lollipop on it from brand new phone.
The scenario is still that there is no way to track down who is draining the battery on unrooted Lollipop? :crying:
I have Google position on, wifi on, bt off, 2 sim with one active for data.
Yesterday the phone lied on a table for about 11 hours before taking the following screenshot, I may have used it (in that 11hrs) for less that one hour not continuously

How can I find the responsible app? Should I start powering off Google position?

Try to reset your device ..! This should fix it..! And that's not a huge drain in my opinion because WiFi , 3g , and auto sync is on always so its Normal 11 hrs standby and still some juice is remaining that's great actually..! ☺

If with reset you mean Factory Reset, I will leave that as last because restoring an unrooted phone is a pain (to be polite! )...
Right now I've followed the (few) steps for unrooted phone from http://forum.xda-developers.com/moto-g-2014/general/guide-how-to-best-battery-life-moto-g-t3049970
configured localisation as "Battery Save"
removed "my face" from Smart Lock
installed Greenify and hibernated (manually... ) a few app
I cannot leave the phone in standby for long time now, I will see on next weekend!
BTW: from my point of view 80% used in 11 hrs standby is not great...

The above steps didn't change a lot the battery drain...
With "App of the Day" I got Battery Booster, actually I'm using it only to its statistics: I do not know how much I can trust them but so far the only apps that are using battery even when the phone is in StandBy are:
System UI
MotoCare
I can understand the first, but what about MotoCare?? Is it a vital component? Can I safely disable it?
I do have only Motorola Alert activated and running, but I can disable it! Both Assist and Migrate are disabled.

N920I Sleep of Death

Ever since I rooted and installed custom roms on my device, the phone would sometimes have a black screen and become unresponsive. The only way to use it is to perform a reset by pressing volume down + power button.
When I go to have a look at the battery history, it shows a gap in the time the phone was non responsive, suggesting it was turned off. However, the battery level also is much less and you can see a downward slope in the battery chart. I have attached a screenshot of the battery chart.
Because of this problem, I reflashed stock Rom and also Sky high kernel to solve deep sleep problem. But I still am getting the sleep of death.
I noticed it tends to come after I use the GPS (Google Maps).
Current config:
Stock rom
Sky high kernal
Twrp
Any help is much appreciated.

You can try another kernel.

Battery life not quite good

Hi everyone,
I have this little phone for about 2 weeks and I've never ever reached a good and consistent on screen time. I've always had about 2-3 hours, although this phone could manage 5-6 hours on screen time!
This is my situation right now (I have 43% battery left)

Is that normal??

If you disable RCSservice you will get at least 20% of your battery back, with no side effects.
RCSservice was invented by google as an alternative messaging protocol, to be added to mms messaging. But it never really took off and from what I can gather, some service providers don't support it, at which point RCS seems to go into some sort of error state, eating battery.
I put some instructions together on how to remove it and reclaim some battery.

Disable wifi scanning under location settings.
'Keep wifi on during sleep' should be set to 'only when plugged in' (under wifi prefrences\advanced)
Try installing Greenify to slow down the wakelocks.
Better Battery Stats can be installed on a non-rooted phone with some ADB commands. This will tell you everything you need to know, what's waking the phone, what's using the network, whats' waking with alarms etc etc. As well as having a helpful thread to talk about what you find.
Using 5Ghz wifi uses a lot of juice, if possible sepearte 2.5Ghz & 5Ghz bands on your home wifi and use the 2.5Ghz. The speed difference is negligable.
Disable sync under account settings . This will save you heaps of battery, but then you're going to have to open Gmail and press refresh to find out if you have mail. Most other stuff works ok with it turned off whatsapp/twitter/snapchat/et all

Here a similar issue with the XZ1 compact. Think battery life is quite disappointing to be honest, felt it was better once upon a time.

My XZ1C battery life is quite good
