Uptime=Awake time and android.process.media (97%

I was having the AWAKE TIME = UPTIME issues, battled all day yesterday with it. My phone is unrooted, Per I post somewhere suggested to do a factory reset, so I did it last night....immediately pushed the power button to kill the display, let sit for a minute, and rechecked the battery....no change!!!! then I went to bed, same thing in the morning too!
Installed a couple of applications.....
as I write this email:
Settings>About Phone> Battery Information:
Up time =7h = Awake Time
30% Android System: CPU Total = 1min
Cell Standby: 29%, Time on: 1h, 23min Time Without Signal:9%
Phone Idle: 20%: 1h3min
Bluetooth: 14%, Time on 44min
Display: 20min
using system panel lite:
Temperature: 90F
android.process.media is having an average CPU consumption of 97%
what is this?
cant stop the task.
suggestions?

Whoa this is scary: Basically a single bad file residing on the SD card could cause this process to go out of control

I had the same problem you have and it was the tvguide application i download from the market, after i uninstalled it my phone is back to normal. Don't know if it is the same for you.

Unknown. I haven't found the culprit yet. On Time is 5.5hrs, awake=0.5 hrs, much better.

battery drain tips?

When I run the latest android build on my Tilt 2, it flies through battery like no other.
Are there any settings I can tweak to get at least a full day's worth of use out of it (mostly in standby anyways)?
Thanks

I'd love to hear anyone's tips as well. As mentioned here:
http://forum.xda-developers.com/showpost.php?p=7959929&postcount=7622
Setting the sleep mode = 1 doesn't seem to work for me. The processor seemingly goes to sleep and enters a coma (yes, I set the clock speed back to stock in the startup.txt).
One quick tip to the OP is set the clock speed to stock.
Edit: sleep mode = 0 seems to work (GSM phone here). However, deleting the "acpuclock.oc_freq_khz=XXX" line from the startup.txt and setting sleep=1 just might work as well.
Edit2: sleep mode = 0 seems to result in the phone functionality breaking. It stopped waking up to phone calls after a while, and calling out wouldn't work either. Damn.. Just a heads up.

1. Close every program that you don't use on startup of android. You can do this with advanced task killer.
2. Run stock speeds.
3. Turn down the screen brightness.
4. Make sure your phone goes to sleep when you are not using it (green led = sleep)

Is advanced task killer installed by default?
Also, how can I clock it to stock? I wasn't aware that it was overclocked past stock.
Screen brightness makes sense, I'll definitely do that.
So, if green is sleep, what is the orange?
Thanks
Smith

I reckon hepatic feedback would drain a little battery on its own probably best to turn that off

This is all true. I'll have to do that.
Still figuring it all out. Once I can get a solid 18-24 hour charge cycle out of it, Android will become my primary OS, easily. Simply works better, IMO

For me sometimes it's green, sometimes it's Orange - not sure how to change it back green -
I use Advance Task Killer, but then i also read that Froyo 2.2 doesn't need a task killer?
The two things that have helped battery life the most were:
-Switching to stock clock speed (the reference over the overclocked BLZN which i loved but killed the battery life)
-turning off background processes... i only turn it on when i have to (using the market, etc)
I would love to hear more tips

The colours are not that hard.
Red/orange = awake
Green = sleeping
If the LED stays red, then your device is doing something, you can either wait or try closing the programs with the task killer. That will help sometimes.
For returning to stock speeds read the faq And advanced task killer can be downloaded in the market.

Thank you guys all so much, big, big help to me!
Android is definitely going to be my full time OS shortly

Its kind of tough trying to go anywhere without a charger nearby. The battery drains quickly and on top of that the actual battery meter is off.
So sometimes that is a main issue

Indeed but that is something that they are working on it as we speak. Give them time

I ran a test last night before going to sleep to see how long the phone lasts.
Charged my phone fully. Ran advanced task killer and killed all the programs. Put the phone in deep sleep ( green light).
Woke up 7 hours later and phone was completely dead. I do have auto sync turned on, but only over wifi, so it should not have used any data as i have the data turned off and no widgets on my home screens that auto-update.
I'll try again tonight for a shorter time (5 hours).
Running the blazn aug 30th build.

How did you 'put the phone in a deep sleep'

I turned off all auto updates.
The next day i did the test again, charged the phone to 100% and used the phone moderately for 8 hours before the battery died.
Without overclocking i can safely say i can get the phone to last 8 hours with moderate to heavy usage, which is excellent.

My main problem with the new updates are that it constantly restarts or crashes after using it for less than 30 minutes while before I could use it for several hours. Not sure whether it's to do with battery life or not as when it boots back in WM the battery is near full.
The biggest things that have helped conserve battery life for me are disabling GPS and background syncing but some apps require this to be enabled. :S

Phone seems to recover from "sleep"
FWIW, I set sleep mode = 1 and removed the overclock line from the startup.txt and the phone SEEMS to sleep and "wake up" just fine. Previously, I had problems with the phone going to sleep and when waking up, everything seemed fine, but the phone didn't work. With the overclock line removed, it seems to "wake up" with the phone working now.
Just a heads up to anyone who wants to save battery life.. might want to remove the overclocking line in the startup.txt..

[Q] Phone suddenly stops sleeping (exactly at midnight!) ?!

Hi,
posted this over at the Cyanogenmod forum already, but xda-audience is probably bigger making it more likely to find help ;-)
--
I am new to CM (came from Modaco ;-) and i would be extremly happy with CM 6.1 if i would not have one very stange issue:
My Phone suddenly stops sleeping exactly at midnight.
It all started when i found that it looses a huge amount of battery over night - it was one of the first days i used CM when i noticed this. As i am experienced with android i immediately checked my up/awake stats and found it was not sleeping properly. As the basic advice for this is always to find the "bad" app that is preventing sleep i treid something and finally thought the issue was gone. The phone was behaving properly the whole day.
Then i got the same issue the next night again !?
To finally sort this is ou, i installed juiceplotter and saw that ...
...the phone behaves fine until midnight - then it stops sleeping and drains huge amount of battery !!
When i start using the phone in the morning again - it seems to behave ok again (sometimes i rebooted - but i think just starting to use the screen again helps as well - not finally sure about this)
So the usual steps to check every single app via uninstalling (which i have all used with MCR-Rom without any problems) would take a while with my 70+ apps as i would always have to wait until midnight passes to see if i found the right one.
Any idea how to find the reason (app) that stops my phone from sleeping after midnight ? Mist be some app that also triggers something at midnight ?
Or any other idea what this could be ? (if not a 3´rd party app)
I checked logcat but could not find anything abvious.
Would really keep staying with CM and not nandroid back to MCR.
Thx
Marcus

It could be an app that is trying to sync at the start of the new day, thus starting exactly at midnight.
In the *#*#4636#*#* menu in battery history select the first drop down menu to "partial wake usage" and see if you can find which process is consuming the most resources in sleep mode.
It is likely that it's a third party app, but you can check that by booting in safe mode and leaving the phone over night to see if it happens again.
If as you say just by starting to use the phone the slowness disappers, it may be an app that is only working when the phone is idle (e.g. some maintenance app, antivirus, etc.).

Thx for the tips.
I checked most of them already ;-)
I found that "E-Mail" was 2nd in the "partial wake" list.
I configured an exchange-account there but set the sync interval to "never".
Nevertheless it is shown (only) with some 20 mins. (for ~6 hours standby) in the partial-wake-list - I found that suspicious.
After some googling today i found this:
http://code.google.com/p/android/issues/detail?id=9307
(this thread says that there is a bug (confirmed by google) that can prevent sleep with exchange-account set to sync never)
I tried to experiment today a little bit (also with setting the clock to 23:55 and wait a while for "midnight" to pass ;-) with different settings and found that "push"-setting shows better results (hard to tell with only ~30 mins. of stats each time). And now i tried with manual sync set to 1 hour (max) and see if that makes any difference.
I´ll dig a little deeper and post results.
In the meantime any tips or comments are warmly welcome. ;-)
Marcus
EDIT: If that "Exchange-bug" should be the reason - i just wonder why midnight seems to be a trigger - but who knows what went wrong deep in the code ;-)

confirmed:
It really WAS the Email-Client configured for Exchange.
No with setting it to "Push" everything is working fine .. when setting the sync to "never" Email start to keep wake-locks !
So everybody with a poor batt-performance should probably check this (if using Exchange) and use "push" until Google has fixed this bug (see above).

Some newbie questions

Hi All,
Great forum, used it a lot with several devices.
So, I just got my Huawei watch and it is great!!
I do have some questions and tips that it will be great if you could help me with and I couldn't find answers to (sorry if its too long...)
1. Charging - what is the best way to charge it in order keep the battery life? like everyday few mins? everyday to full charge? let it drop until X%?
2. Always on option - is there an option to make it sleep at night? like I like this option very much, but as I don't sleep with it, I think it is better that the screen will be off at night.
in addition, do it harm the screen if always on working all the time?
3. Reset - do you reset the devise occasionally? like in purpose. I mean, on my Samsung S6 i know that once in a while I need to reset it to get a better performance.
3. Steps tracking - I was with the blue moon face and noticed that the steps showed is updated after few seconds, meaning that let's say I walked 50 steps, I stop, look at the watch, see the old steps count and after 2-3 seconds it is "jumped" and updated to the new count. in addition, if I stop, wait this few seconds and look at the watch, the count is ok - is this normal?
4. fitness app - which app to use with it that will sync the best with my phone? I installed Google fit and its not doing the job good. it looks like it count steps from the phone and not the watch, or mixed it together, In addition the distance and calories count is way not true, like it show the distance far low then the true (I updated my height and weight, over the app and on the watch) and the calories far more then it is.
In addition I installed the Huawei wear app and it looks much more accurate, showing the steps as the watch, and separate it to walking and steps, distance is accurate and calories as well. but the app doesn't look so good and looks like it missed a lot of other option.
In addition, I don't understand why the Huawei app on the watch is not showing distance but just steps count.
So, which app do you use? I basically want a nice app that will show my daily usage and if can, that will sync with the heart rate measure that i can take from time to time.
Can I sync it to S-Health that I have? or please recommend for another app.
5. Is there any nice watch face that shows not only the steps count but the distance as well?
6. Any other general recommendations?
I think that's it for now
Thank you very much for your help.

Although the screen should not be harmed if always on is working all the time, at night you can use theater mode to turn your screen off without powering down the watch. The easiest method of going into theater mode is by quickly double pressing the button on the watch. You can also go into the pulldown menu from the main watchface and swipe over to theater mode to do the same thing. This can save some watch battery if you have the watch off the charger all night or if the battery is getting low during the day and you want to squeeze a few more hours out. It is meant for if you're in the movies and don't want the light from the watch screen to distract you or others from the movie. To exit theater mode and turn the screen back on, just single press the button on the watch.
Btw your post may be removed since we aren't supposed to post questions here in the general forum. There is a Q&A forum however where any questions can be asked about the Huawei watch. http://forum.xda-developers.com/huawei-watch/general/notice-post-questions-t3367506/page1
Enjoy your watch!

From my experience, it is ok to factory reset your device once every two months or when you feel it has become quite sluggish although you mustn't expect the performance results to be visible right away after the reset. After the reset, all the applications from your phone will be resynced and the Google Play Services will begin to re-download its updates thus resulting in bad battery life and perfomance for that day until it settles down.

Great.
Thanks for helping.

I always charge the watch to 100% and wait until it goes below 10% to charge it.
When I take the watch off my hand I also shut it down and power it on again when I put it on. This gives me about 3 days of using the watch without charging.

If you put your watch on a desk the display will completely turn off after about 10 minutes, even if you chose always on.
If there is no movement detected for a certain period of time, the display will switch off. This can sometimes also happen if you are in a very steady position. My watch turns occasionally off while I'm playing Playstation and holding the controller in the same position.

I noticed that but as inconsistent.
Sometimes it did it exactly as you describe and sometime not. left it on the desk, half an hour and still always on worked.

I don't know the exact algorithm behind it, but I'm pretty confident that the display will switch off sooner or later. I always put my watch on my desk at night and every morning the display is pitch black.

25% battery consumption overnight...

Hi everyone
hope this is a good place for this. I just bought a brand new P2 and yesterday I was doing some configuring for it and updated it to 7.0 (S244 stock). I did wipe it after all the updates according to instructions on this forums. Before going to sleep I charged it to 100%, unplugged the charger and left the phone with all connectivity (wifi, lte, bt, nfc etc.) turned off. I expected 2-5% battery drop but when I woke up in the morning it went down by 25% (!). Also my wallpaper changed to black colour(?). Something's definitely wrong What can I do about this?
Power manager shows the system as the main source of battery drain.
Another thing I noticed is that the video (YouTube, VLC) and alarm sounds are stuttered, there is like 0.5 sec lag every 10-15 secs...
Please someone tell me if this is normal and what can I do? Should I do factory reset once again or maybe flash the firmware? Can that help?

UPDATE:
I have found that the cause of the baterry drain problem is the CPU, it does not go to deep sleep at all and CPU-Z shows that it constantly jumps beetwen 652Mhz and 1401 or 1689Mhz on all 8 cores (even with no apps in the background and all connectivity turned off). Please have a look at my screenshots from GSam Battery Monitor:

https://photos.app.goo.gl/eV8uRP3AZ4SARze03
Clearly something is wrong, any suggestions? Please guys tell me something.

Is nobody else experiencing this? Does no one have ANY suggestions for me whatsoever? I did a factory reset, phone is still losing 1-2% battery per hour with all connectivity and screen OFF. So basically it loses per hour what it should lose during whole night.

Are you on Nougat or Lollipop?
Can you post up the system battery stats from the phone.
Which apps have you installed?

Try these...

Obviously the deep sleep is not happening in your unit. Let's see what is the root of this problem:
1) Settings > WLAN > cog-wheel icon > Keep WLAN on during sleep = Never.
2) Settings > Power manager > Battery saver > On.
3) Settings > Data usage > Data saver > On. Ensure zero apps is allowed to use unrestricted data when Data Saver is on.
4) Charge the device till 100% (do it before bedtime).
5) Turn on Airplane mode.
6) See the per hour drain the next morning. It should be between 0.1% to 0.3% per hour in the GSam Battery Monitor app (assuming you slept for 8 hours).
If the above result is true, meaning, there is / are 3rd party apps that trigger the wake lock activity. But which app(s) to be blamed? Please list down the apps list for us to test in our unit.

@Treboeth, Nougat (s244) as I wrote in the first post. Battery stats after the night attached below.
@azeemzuhair Thank you for your input. Im going to describe what I did. Yesterday I did the factory reset, I didnt install ANY new applications (except for Alarmy but I needed it and phone was losing same amount of energy without it). So the only apps that drain the phone are the system apps themself. Before going to sleep I charged the device to 100%. As for points 1-3 from your post both WiFi and Data were OFF as well as bluetooth and NFC. I left it for the night with screen OFF. These are results after the night (SoT 1 min., standby 9 hours, 22% of battery gone, so that gives approximately 2% discharge rate per hour). This is clearly terrible. Any ideas what next?

Airplane vs active SIM stand-by drain...
Airplane mode stand-by drain @ 0.1% per hour:
Single SIM Active mode stand-by drain @ 0.5% per hour:

Ok, so I left it in Airplane mode for the night and the discharge rate was 0.2%, that is some progress. After that I charged it to 100%, unplugged, disabled the Airplane mode and left it for 5 hours. Battery drain is due to SIM card and phone although they were not used and the signal was good. Everything can be seen in these screenshots:

My hypothesis is that the "Alarmy" app caused the wakelock. By judging at the Airplane mode, Alarmy still wakes the "CPU". You may try to uninstall it and monitor the energy consumption for the next 3 days...

Try "Network Reset"
Still the same? Wipe cache partition in the stock Lenovo Recovery.
Finally, hard reset is the last resort.

Thank your for your reply. Removing SD card fixed the SIM management drain but the "Phone Services" still drain the battery. I did the network settings reset and will see if it helps. As for cache wipe and factory reset I'd like to remind that the whole troubleshooting process started with factory reset so I dont know if that can help.
