Hi there.
I have Nexus 5 running Cataclysm 5.1.
I wanted to make this post because I'm having some doubts regarding deep sleep states. For example, how long should it take before the device enter deep sleep (i.e. < 1%/h discharge rate) after the screen has been turned off? I'm monitoring mine with Battery Monitor Widget, logging discharge rates every 5 minutes, and I noticed that after I turn the screen off, my N5 will often remain using 2 to 5%/h (sometimes more) for at least 30 minutes (sometimes more) before entering deep sleep, i.e. < 1%/h., which naturally causes a little, but not neglectable drain.
I'm currently one of the Lollipop users who are suffering from the Mobile Radio Active bug that drains the battery when on mobile data. Because of this I've turned off mobile data and made a Tasker profile to turn it on every 10 minutes for 30 seconds. I tell you this because in this case (mobile data off) BMW register even higher discharge rates and longer times before it goes into deep sleep. When on wifi this gets a lot better, although it will occasionally remain at ~2%/h for several minutes sometimes more than an hour.
My real question is, is this normal? I'm getting maybe 3h of screen on time, which is not terribly bad, but I used to get more than 4. I'm not having significant wakelocks (Wakelock Detector shows my device sleeping more than 90% of the time), I have a bunch of apps greenified and can't figure out why this happens.
I'd appreciate your help in this matter.
Thanks in advance.

Hello guys,
Have a small question about battery use when phone is idle, e.g. at night. I loose 1%/hour with 3G/WiFi disabled, sync disabled, and 2%/hour with 3G/WiFi enabled, sync disabled. So no sync, no apps updating or refreshing. When I sleep for 9 hours I lose 18% with 3G on, which seems quite much to me. This also used to be only 4-5% with 3G on. While using the phone my battery is fine actually, I lose 2-3% an hour idle with sync enabled (whatsapp, push gmail, hourly weather, tweetdeck every 6 hours). The battery seems to be a bit worse then before 2.3.4, but I'm not quite sure about that.
So I downloaded BetterBatteryStats to see what might keep my phone awake at night (see pics). The slow decline is at night, no sync. As you can see there is one blue block in which the phone is awake but the screen is turned off. However, this wakelock is not present in the BetterBatteryStats output afaik. Anybody has any thoughts on reducing battery use when idle? Cause I see alot of people who lose like 1-2%, I would like to have that as well!

Translation:
Phone Signal
WiFi
Awake
Screen on
Charging
When in normal use my phone doesn't show any abnormal wakelocks, it's just that the battery drains quite (too) fast when idle, can't seem to figure out why.

last night i slept for around 8 hours, before i slept, i had battery power at 65% left, i wake up in the morning to find 27% left! now i think that verrryy much for idle state as my wifi, edge, games, calling/texting and screen were completely turned off for many hours. i look up the battery stats and found that Android OS had consumed 51%. below is the screenshot.

somebody please tell me why is that? and how do i get more life out of my battery?
Maybe your phone only goes up to 9 hours...
Maybe it's kernel related.. Are you on custom rom already?
My Droid on a JB ROM has the Android OS consume about 90% of the battery and it dies after 8 hours of screen off time, airplane mode. *shrugs* if anyone has a solution id like to know.

This has probably to do with something that is running in the background.
your phone apparently doesnt go into "deep sleep mode" Only in this mode you lose just few % per night.
I recommand to shut off your phone, take out the battery for a few seconds, put it back in, charge it in one go, then turn it on again. See what happens.
You can, of course, sleep with the charger in.
Welcome to Android, for the most part, our battery life sort of sucks :/
Hello XDAres
Read this as a foreword - it's not a must
I've been using my OnePlus One for about a year, and at first the battery was great, but after upgrading to CM12S it seemd like it got much worse. this case wasn't only for me ofcourse.. many other users of CM12s and basically any Lollipop device had complained about a decreased battery life. their evidence to that was their SoT- which used to be (and I'm talking about the majority) around 4-5 hrs back at KitKat days, and had dropped down to 3-4 once they had gotten the 5.0-5.1.1 Updates.
that was caused by a number of things- among of them was the Google Services Wake bug etc.
Now to the point-
My OPO used to get 4.5+ SoT ( Screen on Time) back @ Kitkat days. since the upgrade to LP it went down to 3-4 max.
And then I've tried something-
I simply changed the settings of display, to turn off the display after 30 minutes of screen idle (it was 15 seconds before).
And the results?

}
The suggested conclusion is- SoT is a lie.
If prior to the changes I've made on the display settings, I'd get ~15% @ the end of the day ( say 11PM/23:00 ) and a 3.5hrs SoT, I can now get to ~5% at the end of the day ( again 11PM/23:00 ) by simply raising those values. does it mean that I've used the phone more? well, no, it simply tells us that SoT isn't that trustworthy as we thought.
Opinions?
Of course your screen on time will be better with a 30 minute timeout. But all you are doing is having it sit, doing nothing until it finally times-out.
But yes, the way you're doing it is not telling a true screen on time with actual usage.
Most people's screen on time numbers reflect the phone being used during that time. :good:
Connected to wifi, played Tsum tsum for 15mins, SOT 30 mins
adaptive brightness was on
screen brightness was similar to 40% when adaptive brightness is off,
location was off, wifi scanning off
I was not expecting that kind of battery drop when screen on
I'm also noticing that the phone isn't deep sleeping sometimes
Thanks for helping!!

Sounds about the same as mine - around 4 hours SOT and I usually get about 24 hours total from the phone. Also stays awake for seeming no reason. My Z3 was way better in this regard.
Same here! Did Factory Reset solve the problem?

Is there any "benchmark" or normal battery usage for this?
Somehow I seem to get rid of the awake issue but don't know if it really helps
i turned off Settings-->security-->trusted agents-->smart lock
And turned off all apps with usage access except stamina mode and greenify
Also turned off location when not used

Take a look here: http://forum.xda-developers.com/xperia-z5/help/battery-drain-factory-reset-t3277136#post64482472
So basically just out of nowhere, about 2 weeks ago, my phone's battery just starts dying really quickly when connected to WiFi. I am talking from 100% to dead overnight (7-8 hours). It's an S6 purchased on release day, original battery, but before this issue, I could easily go a day with normal use and have 40% or more. Even now with the problem occurring, I can leave WiFi off and still get my normal battery life.
No settings have changed (I have always had all the suggested battery saving settings set appropriately), no system updates, just usual app updates. I figured an app update caused the issue so I factory reset the phone with no luck. I ran a suggested app, GSam, to check for usage. It hasn't shown any apps consuming the power, just power draining very quickly when WiFi is enabled.

Not sure why this screencap is so huge, it won't let me resize it on here. Anyway, it's a screencap from GSam. The first half shows during the day with minimal use with WiFi off. The steep drop just before the green line is usage when I get home and have WiFi on. The solid green line indicates charging. After that is the overnight period with WiFi on, massive battery drain.
I'm at a loss at what to do. I really like this phone and this WiFi issue is killing the usability of it. If I'm at home and browsing apps with WiFi on the phone dies so quickly. If this were an issue regardless of WiFi, I'd understand that it's just old and a dying battery, but it's only ever present when WiFi is on.
Besides trying a custom ROM, is there anything else I can try to fix this? I don't have it rooted and would prefer to just keep it official firmware only if I can.
Thanks in advance.
