I have been having an issue recently with my battery draining rather rapidly. The phone is warm to the touch most of the time. I downloaded BetterBatteryStats and it confirms the phone almost never goes into deep sleep. The partial wakelocks are minimal. It appears some kernel wakelocks are keeping the phone awake. 7-0022 has the most usage. Any ideas?

Hi
For the last one week my battery drains faster and the phone app takes most of the battery.
I normally use CPU spy and Usually my phone would be in deep sleep mode for almost 95% but now it has dropped to 72.5% and some service on 1100MHZ takes 18%.
My BBS shows the following info.
Can you please help. Thanks in advance.
70% deep sleep is not actually bad.
Could be due to roaming ?

Hello guys,
My optimus g does unusual battery drain during deep sleep. Before about 2 months the battery consuming in a sleep of 8-12 hours was max 5%. Now after a sleep of 6 hours its draining 15%(!!!) with only WiFi on. My phone seems to be awake 8% through wakelock detector and the only apps that shown by Gsam battery monitor that using battery are Kernel(Android OS) for 21,5%,Google services for 6%. I am with stock rom and kernel no rooted.
Any solutions? thanks in advance.
Hi
I am having this problem also. At first of July Google Play Service were updated, and from then my battery goes as yours. I have tried all except hard reset. In internet I have found many threads that talk about it, but none has the trick for me. I am desperated. I am waiting for 4.4 in my device and will see.
Did you find any solution for this problem?
Regards
FermÃn
I got 4.4 before one week and now the battery is way better than before!
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.
Im having big battery drain with those 3 wakelocks:
ril-fd,
powermanagerservice.wakelock,
bam_dmux_wakelock
I have 4% activity level with Wakelock detector which is better than 19% that I started with but still not perfect.
During the night I had "PhoneApp" draining 11% of my battery, it has vanished after reboot, will check it again tomorrow morning. Im gonna drop some print screens a bit later but can someone please help me with those 3 wakelocks?
I read on this forum that those wakelocks might be contected to Fast Dormancy but came to conclusion that its not present in 4.4.2 KitKat? is that true? If its not there maybe that the issue? is there a way of acquiring it?
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..
