Hi guys, i performed a factory reset to my opo, but now i have a huge battery drain. I think it is caused by the Wi-Fi but i don't know why. I disabled location, autobackups, ok google detection and stuff like these. I also noticed that the wifi is active also when the phone is powered off. Any advice?

The huge drain is caused by your weak cell reception. As you can see the drain is minimal right at the beginning when you were not using your device at all.
The drain starts at the same time when the reception starts to get bad (red).
But, you also started using your device quite heavily at that time (active + screen on for longer periods).
Were you on wifi all the time or did you use mobile data and only had wifi left enabled?
What was you screen on time at the end of the day?
Without more information about what you were doing with your device I would say you were on the go, maybe on a trainride with bad cell reception which uses much more battery.
To be honest the battery looks "OK" to me in this case.
About the gap + wifi usage, might just be a statistics bug, I don't know.
Charge your device and go on monitoring your battery... there are bad days and good days.

Hi,
can somebody give me advice? I have quite big stanby drain. As you can see cell stanby and phone idle are high (around 12%). I lost about 10% of battery at night for 6 hours with wifi and data off..I am using latest radio and latest insertcoin rom. Thanks in advance.

Check the running apps in task manager at night before you go to sleep. There may be a game or an app which takes a large amount of RAM and battery power.
Losing 10% overnight is about what I have always seen with my phone..

I killed all tasks just to be safe..didnt help. I got about 180mA when idling which looks bit much. On my old Desire it was 3-5mA when sitting overnight..
There are plenty of threads on battery issues and how to minimize battery loss ... but otherwise one just have to live with the fact that batteries have not improved that much over the years as we would have liked to see.
So i have been experimenting with roms/kernels in the past few days and have noticed android system is almost using as much battery as the screen. What causes this? I never had this problem before I rooted. I am currently at 69% and my screen on time is only 1 hour. I have tried many kernels and I can't get any more battery life out of the phone. Other than the obvious stuff, what can i do to get better battery life?
You have to show us the BBS log. (Better battery stats) for wakelocks.
I only get like 16 hours of battery life and I could really care less because even if I was left at 60% when I went to sleep it would need to be charged or I would potentially be left with 20% the next day assuming I had the exact same usage and that isn't comfortable so I charge every night.
Keep in mind your cell signal. You can also switch off mobile data or switch to edge or 3g instead of LTE.

Hi,
I recently had my droid maxx replaced because I was getting less than 2 hrs screen time and overall my phone lasted hardly 12 hrs. On the replacement, I have had the same problem and I haven't been able to figure out the reason behind it. I typically keep bluetooth on all the time because I have a moto 360 and bluetooth in my car. Additionally, I typically have my location services set to 'high accuracy' since I use gps to check traffic everyday via Waze (it's pretty annoying to have to turn it on/off twice daily).
One thing that popped in my mind today is that could NFC be responsible? I have a silicon adhesive that I use to store my ID, a credit card, and my ventra card (Chicago public transit). The ventra card uses NFC so I was wondering if my phone might be constantly reading it, and result in the excessive battery drain. Has anyone seen this before? Below are pictures of my screen on time along with the general battery stats. If the low battery is because I'm lazy and keep bluetooth/location services on all the time let me know - but I didn't think the drain would be that excessive. Any tips/advice would be great!

Can nyone help me out with why this happens, only sometimes??
This time it looks like the main culprit is the kernel, but i have no idea: how id fix it, why its only sometimes, what else i oculd do to prevent it. i have even de-greenified google play services and google services framework as they never seem to stay hibernated. Yet this still happened, again....
i also noticed hsic was kept awake for a while, but since im not sure what it is, maybe that is normal...
help??
If it was always draining like that every night, id say maybe its time for a new battery... but it only happens once every few weeks, at most.
it was in the upper 80s last night percent wise. all things in the regular battery usage screen looked normal with screen showing the most usage...

Which phone is it? Go through the apps you installed just before it started and try uninstalling them one-by-one and see if the problem still persists, this helps eliminate those apps. Other than that, factory reset? Probably not what you wanted to hear but that will 99% of the time fix the issue.
Before I was getting 14h total time, with 2.5h SOT time before being forced to charge.
So I did the fresh reset like was suggested. Battery life is FANTASTIC now..... SOT 30M, LFC 3.5h, time left 2d 13h.
However, if I flip on WiFi, my phone will drain quickly, for some reason, I think it is either constantly searching for new WiFi locations and/or it is keeping my phone awake constantly.
Anyone have a remedy for this?

Now look at it afterwards
I only got mine yesterday, but I have noticed the battery life is terrible also. I found a setting in wifi called 'scanning always available', which I have disabled, this might be our culprit.

I have been looking at that as well.
I would check for wakelocks while WiFi is on. I also double-check the app settings for syncing while on WiFi.
