Around 3 days ago, my phone has turned from around at least 6 hrs of SoT to around 2-3, even while only leaving it mostly in my pocket. This happened after i factory resetted my phone, for some odd reason. When the CPU usage was usually below 50%, this time it's AT LEAST 70%, often reaching to 100% for no reason. The process "Android System" on the battery usage screen takes up around 40% of my battery drain. I had google assistant at the time, so i thought it was the problem.
I factory resetted my phone again yesterday, and it fixed the problem temporarily. Assistant became now on tap again, and Android system only used up around 8%. But the battery drain just came again when i woke up today.
Does anyone know what CPU process might have been the cause to this problem? Or else I'll just factory reset I guess, but i'm scared it'll happen again and again.
Note: My smartwatch, root, substratum, and KLWP aren't the cause, since last week when I used these things my CPU usage was fine.

Help pls ;-; phone is really unusable for long periods of time
Edit: Got CPU usage down to around 10% most of the time using this APUS Booster app I found, looks shady and bloatware-y as **** but it works i guess. Have to do it everytime i restart phone though
reflash the rom.
I think the problem is with pocket mode \ proximity detection.
Try this experiment:
Cover prox sensor with one palm and try to unlock using the fingerprint scanner. If pocket mode is on, nothing will happen. Phone won't unlock.
Now shift palm covering the prox sensor slightly away and repeat above. At some distance you will be able to unlock phone.
My hypothesis is that if one keeps phone facing the body, pocket mode may not get activated allowing the fingerprint sensor to keep sensing one's body (capacitive) and the phone won't unlock but every movement will keep on making the FP scanner work heating and draining battery.
This did not happen in 7.0. But 7.1.1 update seems to reduced sensitivity of proximity sensor.
Workaround: keep phone in pocket with screen facing away from ones body.
Hope this works.
The proximity sensor works well enough except* it's clearly constantly draining your battery
I'd just turn it off
I don't have 7.1.1 yet so IDK about how the updates have changed things. It works well on 7.0. but clearly that's going to burn a lot more resources than it's worth

hello, as anyone tryed how is the battery life on a full charge - on airplane mode?
can we get near a week of usage watch/chrono etc?
thank you
Bluetooth consumes but a fraction of the neergy the watch needs - most of it is needed for display, memory, processor... I don't think you'll see a much improved life in offline mode - maybe just because you won't be getting notifications, but that would still save just a small amount of energy the watch usually needs.
I tested at night with screen Off and airplane mode. It drain 9% in 8hours.
And that is about the same drop I have leaving the watch overnight: connected just the "Always On" on off. As Zvieratko says, very little impact, only the screen is relevant to fast or slow battery consumption.
The battery life sounds disappointing on the LG G Watch R. I really like the watch and want to get it but I want to be able to stretch the battery life to a week so I only need to recharge it once a week.
Right now I'm using Samsung Gear Fit in offline mode, Display Activation on manual, monitoring my steps, only connecting via BT to my Note 4 before bed each night to sync. With its puny 210mAh (vs Watch R's 410mAh) I am able to make it last 7-8days. With BT on all the time, maybe 4 days.
In airplane mode with the display off I get about 1% usage every hour, so I guess it will last about 4 days on a single charge, however I see no point in this mode. I want to be able to look at it at any time so display is always on, and I want to see my notifications, so it's never in airplane mode. It lasts between 1.5 and 2 days like this.
Since I take it off before I go bed anyway I don't see a problem. The charging cradle is nice, it's not like I need to plug a lead into it. Now that would annoy me.
Of course it could be a problem if you are camping - sorry, can't tell you the time, my watch only lasts a day on a full charge.

But now we have a lot of USB (tiny) power bank we can charge several time your watch, so you can have it on your bag

Or considering my watch only has a 400mA battery, it could quite possibly recharge of a solar cell stuck to my back pack
Hi,
Why I lose more battery with screen off than with screen on?

EDIT : solution find : I've switched my WiFi network on my Nexus 6 from 5GHz to 2.4GHz
Can't be sure. Seems like some Google service is out of its mind. Same on Lollipop. Not sure if its the same source but looks similar case.
Also have a look here http://www.ibtimes.co.uk/most-commo...arshmallow-nexus-devices-how-fix-them-1523719

to be honest with you, after looking at everything, im guessing that its your wifi router. i had a similar probkem a few years ago, and it drove me nuts. eventually i figured out that it was my works router. after we changed the router, my mysterious battery drain stopped. now what kind of battery do you get on mobile data only?

This is a day without Wi-Fi (juste few minutes at school and at home), most of the time, i was connected in LTE . Strange for Chrome.
there are issues there, but what fo yoj keep brightness at, your screen battery loss is relatively high, unless yoj kerp your brightness high. i keep mine from 0-10%, for every 30% i raise it, i lose one hour sot.

I will try a day without adaptative brightness and with a low brightness.
Hello everyone!
After switching from stock to Chroma to have more options, no resolution of my problems appears.
I have decided apply an agressive Doze mode with Doze Settings Editor, but no changes.. Seems that my device doesn't enter in Doze mode.
So, I have swtiched my WiFi network on my Nexus 6 from 5GHz to 2.4GHz and .. my device goes into Doze mode!
I can reduce my battery drains screen off by removing the wlan_rx_wake, but how?
Now, I need to know why my 5GHz WiFi is the cause of my problems! If anyone knows the answer ..
Thanks to everyone that have tried to help me
hello everyone, here is my problem - in last couple of week i'm having really big battery problems (to the point i'm thinking of smashing my phone to the ground ) I take my P9 of the charger and it says it is at 100%, after only few min it drops to about 90%, and when i open some app (facebook atc) it freezes and when i try to turn it on again it says 0% battery!! when i hook it up on charger it takes 20 mins to charge to 1%, and when i turn it on again it says anywhere between 40% and 100%!!! Freezing most commonly appears when i turn on my camera and take a picture, it snaps then freezes. Tried with the factory reset it didn't help.
Please anybody!!!
Most likely the battery has worn out. Is it still under warranty?
Same here, sometimes camera apps freeze and then i will reboot it. After reboot, phone shows 5% power and then force itself into shutdown. The battery actually may not empty as told by phone, when i start charging, it shows more than 5% and phone actually have juice to run longer.

Sounds like a battery replacement to me. Have to tried installing AccuBattery or anything similar to check the battery health?

It's not the battery causing this fault

I have replaced the battery in my P9 and it still gets a power drain when the camera is operated. This usually occurs in low light environments. If I immediately turn the phone back on it starts up with maybe 20% battery, which then drops 1% a second and gets hot. This is with a brand new battery fitted. I conclude there is a glitch with updated software. Hopefully Huawei will read these posts and correct with future updates.

Not the battery
Try removing your sd memory card. I think a malfunctioning sd card was causing issue of battery drain during camera use. I can't explain the full science behind this, but my p9 phone has been fine since I removed the sd
I've had my SM-T810 (Tab S2 9.7, wifi) for four or five years now. A year ago, half of the screen began flashing brightly if I tried to use it on low brightness. To solve this, I turned up the brightness a bit and used the app Darker.
Over the last few weeks, things got much much worse. The tablet required more and more brightness to avoid flashing, it would stutter when playing videos, and responsiveness was slow. Every so often it would lose WiFi connection when my other devices didn't have trouble connecting.
Today, there has been some type of catastrophic failure. I was watching a video, when suddenly the video stuttered, froze, and the tablet became completely unresponsive. None of the buttons worked at all. It would not turn off. After about 15 minutes, the screen began its old flashing routine...and then something new happened: the flickering was joined by colorful lines, and about five minutes later the tablet shut itself off. It had become quite warm around the volume rocker/card slot area.I can't turn it back on, but if I plug it in, it shows the battery percentage. The tablet has never gotten wet, and it hasn't been dropped recently. Any thoughts? Thanks in advance!

Is the battery indicator dimmer than normal? Normally I would just assume at least the screen is bad, but since the charging indicator seems to work? Perhaps you should try download mode? Odin over fresh firmware? (You will lose data on the tablet though)
No, the battery indicator doesn't seem dim. I'll have to try your suggestions. I'm starting to think the motherboard is bad, and that would help me determine if it is or not.

Maybe some files in EMMC corrupted? Then if ODIN works it might get it back to life.

I have no idea why this is happening. It's been 2 weeks since I purchased the phone. The screen time is showing 1hr 23mins but the phone was idle at night. Is there a fix for this issue?

Something is keeping your phone from deep sleeping. When the display is off it can be in one of two states, one is the phone is still on, CPU is running but the screen is blanked out, this lets apps continue to work, for example sending an email you've just sent then turned off the phone. Then after a little bit more time the phone goes into deep sleep, this sees everything frozen so nothing is running and the CPU is off. It should be in this deep slate state most of the time you are not using the phone. What can happen is applications take a wake lock, and stop the phone from going to deep sleep, and over many hours that really drains the battery.
Restart the phone and see if it is now okay. Consider what applications you have installed recently that might be causing the issue.
