Mate 9 build L29b185c172 power consumption - Huawei Mate 9 Questions & Answers

I updated my phone yesterday and the log was about system optimization and power consumption, but I noticed that it's consuming more battery now specially in idle state. So anyone else is facing this problem?

Battery problem after polish 4.4.2 update

hello,
yesterday i installed the official 4.4.2 rom from poland on my belgium/luxemburg note 3. i performed a factory reset to be sure.
today my battery was hell. just a half an hour ago my battery drained from 15% to 1% in 15 min with just sitting in my pocket turned off and warm.
i checked my battery stats and my exchange is using a lot of it.
are there other who have the same problem and maybe have a solution?

Hi
1- Install wakelockdetector and see which program has high battery usage ...
2- stop exchange service and disable it

I've got exchange services running, but it doesnt appear in my battery stats. It seems quite high, maybe your email is syncing a lot. Try changing the sync schedule to either manual or push.

Well i don't speak dutch but from what i see your CPU is not "sleeping"... install that wakelock that the other user recommends and you will see exactly who is messing up your cpu

i cannot install wakelock because it says it needs root on kitkat to work.

Random Reboots and battery drops

What's the best way to diagnose something like this? It happens randomly and I'm not sure what's causing it. I'm stock rooted.

Your wakelocks or horrible. You need BBS as stated, but the instant drop is indicative of a bug in the stock rom or kernel. If it keeps doing that after the wakelock issues are resolved, you may need to flash another rom.

Does this pretty much mean Google search is messing me up?

I think Google search incorporates Google Now which yes, mega battery drain in my opinion especially if it is polling for location constantly.
edit: that looks like my battery stats when I don't try to conserve energy and have heavy usage.

So how do I fix this? Turn off location would somewhat render Google Now to be useless, as does turning it off.

If you're getting reboots, grab /proc/last_kmsg the next time it's on. The last few lines should give you some hints as to why it rebooted.

Kk thanks a lot guys, I think the battery issue overall might have been Google search so now I'm going to try to fix it. If my phone reboots again I'll check the file to see the logs.

Battery usage

Hi guys, I've just bought a Motorola moto g 16gb and then I've installed android 4.4.2 and I noticed that the battery stats doesn't show the battery usage of many user apps..
Is it a bug or not?
(Before this phone I had a HTC desire c with android 4.1.2 cyanogenmod)

It is not a bug.. android does not show user apps battery data anymore..

Ah.. I found it very useful sometime..
And is it normal the percentage of battery used by the screen? (I keep it around 30/40% during the day)

It does, but it won't show any user app that is less than (I think) 4% use. He's got a user app showing up on the list in his screenshot.
What has changed is that some user app use of core OS features now get reported as Android OS/Android System where as under JB they were reported as the originating app.

Hey @smoza I noticed in your screenshots you're using a battery percentage app. Did you know that KitKat already supports battery percentage? You can enable it with this app, without root https://play.google.com/store/apps/details?id=de.kroegerama.android4batpercent

OK, really need to know battery consumed, how much of that is reported to be the screen and the screen on time to see if that is an issue. It is normal for screen to be top of the list with regular usage but how much it drains (and how much screen on time you get) is basically going to be a function of your brightness settings.
Looking at your second screen shot I can see a couple of things you might want to investigate/change.
Wifi is always on - fine if you are actually connected to wifi - but if you are out and about and not using a wifi connection having wifi enabled will add a significant amount to your idle drain rate. You should also disable 'Scanning always available' in the Advanced Wifi Settings (Settings/Wifi/Menu Button.Advanced).
Your cell signal is often quite poor - not a lot you can do about it but that will cause faster drain when you are connected to mobile data.
Your phone is waking up regularly when not in use. There could be numerous causes for this, but most likely it is having location set to High Accuracy or Battery Saver - the phone is regularly collecting info from your cell tower connections and surrounding wifi networks to feed back to Google to get a location fix, and apps that like to know your location may be asking for a fix regularly. Depending on what you use location for you may wish to consider turning it off entirely or running in Device Only mode.
You've used GPS - some people have experienced an issue with a continually higher drain rate after using GPS - it's intermittent - for some it is everytime after using GPS, some most of the time, others very occasionally. A reboot will fix if this is an issue (it doesn't look like it is a problem but it's hard to tell - it's most obvious if the battery drains in airplane mode).
I turned off the GPS right now, disabled 'scanning always available' and set the brightness as auto.. I'll write here if this will increase my battery life or not, thank you anyway

You might want to keep it between 10 to 20% manually adjusting to higher levels if you're going outside, for the brightness sensor to not be working and therefore, consuming more battery.
From this morning at 10a.m. with 94% of battery I reached the 9p.m. with 7% of battery and I used it a bit more of my average use.. That's better than before (I had to charge my phone at 8p.m.), so thank you guys

There is anything to do to fix. this bug? The phone had aroun 70% of battery and the phone shootdown it self and you can see the results, 0% of battery but the phone is still working.
Here you can see the screenshot, i'm running stock ROM with aerokernel, and xposed and Gravity box.

Battery life is great. I also wanted to not have to root my phone but I didn't really have no choice because without root it wouldn't go into deep sleep. But with the update it's sleeping like a baby without root. Great job samsung or google. Lol

Try buying Greenify from PlayStore then use ADB to activate Aggressive Doze (Greenify guides you). Should help.

Mine was draining the battery because google play services was acting up. Do You use Greenify or any similar app? I use Greenify and found that if I hibernate any Google apk play services goes crazy and I get more battery drain.
