Hi there guys, I've noticed over the last week or so that I've had my phone that the biggest battery drain by far is the phone idle (12% vs 3% screen). is there a way to lower idle power consumption?
Install GSam Battery Monitor (or similar), run it for a day or 2, look which processes uses most power, specially keep an eye out for unnormal Wakelocks (needs ROOT'ed phone).
My phone idles at about 0.1% per hour (ROM 20150907)

Same issue her. Battery statistics says Google Backup transport, which points to the lillipop battery drain bug..

Hi,
I used the app Current Widget to manage my phone battery.
I just caliberated the battery an hour ago.
Now, when I turn off the screen and left it on standby for like 20 mins, I got the log report on the battery which said -4000mA (or something like that) every minute.
Is there anyway to improve this?
Thanks
Also, I have rooted my dvice to ARHD 1.2.3. For the last 10 mins, the log files recorded -4268mA constantly
I believe the standby drains aren't reading out correctly.. i have the same issue with battery monitor widget. Imagine with a drain of 4000mA constant the phone would be dead within ~25 minutes (as the capacity is 1800)
Yes, I think so too, hence I uninstall it and use battery monitor widget instead. Now it measures about 100 mA in standby. Is that normal for the One X?
Even 100 i think is a little high, because the companion core should kick in @ standby.. and that's the problem at the moment with the monitoring apps i think.. sometimes battery monitor is reading 4-10mA drain but sometimes as high as 1000+
I was curious what kind of idle battery drain people are getting on their tablets/ROMs?
Measuring with Battery monitor Widget Pro, on my 8.4, running stock TW except for Towelroot, I am averaging -150ma.

Since I have an amper cable I can see the current the tablet draws when its plugged in with screen off / idle and fully charged. mine does this
0-0-0-0-0-0-0-0-0-20-0-0-0-0-0-20-0-0-0-0-0-20
so I would say its draws a quick 20 ma every 10 seconds - but since its plugged in it might not be in the deepest sleep setting that it would be when on battery.
anyways I have no problems with it staying at 100% or 99% leaving it off for the whole day unplugged so it has very good power management in my opinion. - just have to keep the wakelock apps in check
I updated from the ng1 build to the latest nk1 build and my idle battery drain is much improved with the exact same setup running. Now down to -40-50 mah.
I have terrible battery drain randomly for no reason and I don't no what is causing the battery to drain so much. I have attached an image is there anyway of seeing what causes this much battery to drain so quick?

You should install better battery stats, available here on XDA, to pinpoint your battery usage.
Looks like there was a really battery draining event that occurred quite suddenly?

I noticed in the screenshot you have might GPS on, there could be an app running in the background abusing GPS or polling it too quickly (look for a blinking / solid white pointer Icon in the top left of the statusbar, this will tell you if something is requesting location).
GPS will drain battery very quickly and should be disabled unless it's needed.
Using Battery Monitor WIdget, my OnePlus One phone on CM12 has an average Deep Sleep standby current of around 8 mA.
Using BMW on SM-T800 stock 5.0.2, my Deep Sleep standby current was around 85 mA ... 10 times as much!!!
That's insane.
I disabled/uninstalled a bunch of the Samsung bloatware apps, and things are a little bit better: Averaging around 45 mA now.
But, that still seems insane. Shouldn't Deep Sleep get me lower than 45 mA?
Unfortunately, I can't get Wakelock Detector working on the SM-T800.
What is your average Deep Sleep standby current? And, are you running Stock 5.0.2 or something else?
Isn't anybody interested in improving their battery life? I know I am.
Just installed it, I suppose you leave the tablet for an hour then check the log file to see how many ma were being used when the tablet was supposedly in deep sleep mode.
I use GSam Battery Monitor for the Alarms, I am looking for an wake-lock app that works without root, I am always lloking for ways to save battery power.

Hi, @Tinderbox (UK) - I usually leave my tablet or phone idle overnight, so you can see a good pattern. With BMW, you can display the battery draw in mA, and set up the history tab to see the mA draw per reading.
Showing the % battery drain per hour is useless - If you have a big battery, the numbers could look small, but your current drain may still be higher than you want.
The maximum i can get 1% to last in standby mode is 23H47M i was busy and left my tablet unused for over 24Hrs
The T705+ and T805+ have cell lte transceiver so they will not get as good battery life as the wifi only Tab S.
I have use Titanium Backup to freeze 6 unused apps, and used Sony Power Nap to keep my T800 from waking up due to waklocks so it spends as much time in deep sleep which use the least power.
Free Kapex Battery Monitor, to monitor how long your battery stays in every 1% of battery capacity.

Free, Needs Root, CPU Spy Reloaded, to view wakelocks, it is easier to use than Wakelock Detector and look better.

Hi!
As many, i had the problem of battery drain (it would go from 40/45% to 0% in a matter of minutes).
I orderer a new battery (not the Kompson one, the original Jiayu battery, at least it was sold as original and it even has the same serial number my previous battery had), but the problem continued!
Anyway, after much testing, here is the "solution" i have found:
As soon as you see the battery drain starting (it´s very easy to notice as you already know), go to battery settings and look at the percentage that each process spends of battery. Usually, before battery drain starts, everything looks normal, low consumption throughout all apps. But when the battery drainage kicks in, the last app you opened has an unusually high battery percentage consumption. For example, i have seen my ColorNote app at 45% consumption, Whatsapp at 50%, Reddit at 48%, etc...
These are all "normal" apps, not some shady app power hungry. What i do is, after i identify the app with unusual high power consumption (again, it´s usually the last app opened after battery drain starts) i long press on it (from the battery menu) and the i choose "Force Stop" on the app.
This immediatley stops the battery drain and the battery behaves normally and goes out at a normal rate until 1 or 2% battery!
I have tested this many times and it never failed me. Please try it to.
I think there is a little chance to catch the very moment when the battery drop start. Today I've got battery drain very quickly between 50%-40%.
I also tried some these "fixes". But the only solution is to change batteries.
people and me personally, have also found out that the enabled auto brightness control , often consumes a lot of battery after about Android 6.0
have a look also on that.
I've just tested a new Konpson battery and the battery drop changed. With originally Jiayu battery I have drop with 25%, now after 10% I guess and phone can hold some times (30 min approximately) at 1%. It's a little bit progress ;()
