[Q] suspend process

Hi guys. I bought my O3D last week and already problems accured. My battery does not last longer that 3 hours, tops. I installed the System Panel APP and kept monitoring it for a while and noticed that there's a suspend procces and i using the 100 % of my cpu and with that, my battery aswell. I asked around what to do and the answer was to set up my display to never turn off...but i don' see that option in the settings tab.
It's running on android 2.2.2.
Can anyone please help me?

Battery Problems

I'm using a Nexus 5, its my first Android device, and so my first time rooting.
I rooted yesterday using the Android SDK, and installed TWRP.
The root worked perfectly, and I have tested it. All I have done since rooting (unlocked boot loader at the same time, so I'm clean on stock), is install a few Play Apps like Twitter, WhatsApp and then BusyBox and dSploit.
I haven't added any customisations or anything, and my battery is now awful!

My screen has been on for 50 minutes...
I have brightness on the lowest setting, have turned off vibrate on touch, turned off Wi-Fi, turned off Location, set to use 3G not 4G, set display to turn off after 15 seconds...
Im sure it can't be anything to do with the root, but I don't really know too much about it. Is there a problem with 4.4.2 and battery life?
What else can I do to improve it?
Ideally I'd like to be able to have a max of 3-4 hours screen time, and the device to last for 14-15 hours.
I was easily getting 14 hours before I rooted/updated, but now my battery life has just screwed up.
Why is the OS using up so much?

Is this not the first charge since you first saw the problem? The Android OS bug occurs sometimes. I would reboot and see how it is on the next full cycle.

sreen may be turning in coz some apps might be asking for root access.
I think you try greenify app and hybernate useless apps, m sure this will help you.

[Completed] My phone NEVER goes into deep sleep (Samsung Galaxy S6)

Dear all,
I am writing this post to hopefully get some help or directions regarding my issue, because I have already spent hours and hours looking on the internet trying fixes on my phone without anything working for me so far.. So I am getting a bit hopeless....
I recently got a Samsung Galaxy S6 (SM-920I model), and since the beginning i have been shocked by how CRAPPY the battery life was. To give you some ideas, my phone loses around 3-5% of battery per hour when idling and screen off, meaning I am not doing anything at all with my phone. Overnight, I lose about 15-20% battery with my phone on airplane mode, power saving, or whatever else you want, when it is not doing anything at all..
I know that my problem is a deep sleep problem, quite easy to identify i guess, so I have spent a lot of time reading and trying to fix it by myself but so far nothing worked.
To give you some background, after unpacking the phone I quickly upgraded Android from 5.0 to 5.1.1, so I cannot tell how it was working at 5.0. It is only after that I saw that a lot of people have issues on 5.1, but it is strange because just before having my S6, I was having a OnePlus One on 5.1 and I didn't have such battery problems and everything worked fine except turning off the "keep awake" setting option for GooglePlayServices.
What I can say though, is that since I upgraded I never had so much difficulties trying to fix a problem on any Android phone than before. Basically, since day 1, my phone never went a single time into deep sleep mode.
So far, to fix this, I tried all the following:
- Reflash the stock firmware (Samsung 5.1.1) --> many times, with full Cache/davik wipe and factory resets
- Root my phone using UniKernel
- Install custom ROM (I am running XtreStoLite version 2.2) + all kinds of wipe/factory reset
- Flash different kernel that are shipped with the ROM (there are 5 different ones if I remember)
- Use my phone with only stock apps (to see if the problem comes from one of my apps)
- Cold reboots
- The "DeepSleepFix" using the Android terminal as described on some forums (cannot post the link for now since I'm new..)
- And desperately, try to use my phone normally for now
Overall, I would say that my battery would last roughly 15 -20h in total with normal usage, not even heavy, which quite sucks..
I can show the no deep sleep issue easily to you with some screenshots (will put a link to the screenshots here when I have 10 posts... for now I can't..) , I have tried many applications to try to find the root cause such as:
- WLD
- 3C CPU
- BetterBatteryStats
- GSAM
etc.
I am monitoring my phone closely for the past 1-2 weeks and so far I have never seen it being in deep sleep at all (ah yes... 0.2s in total max all the time..). Also, when I check on the default Battery menu of Android, after a full day I would usually see "Android OS" on top and using 20-30% of the battery at least.
The problem seems to boil down to a process called "LHD" in the kernel wakelock. This is keeping my phone awake 100% of the time, whether I am using the phone or if I am not. However, even with this info I tried to search online and I cannot find anything about "LHD", so I am really stuck right now.. Do anybody knows what it is and why it is a problem for me?
If any of you have a solution or can give me some guidelines to help me fix this issue, I would really appreciate any help. If you need more information from me also let me know.
Thank you for taking the time to read me,
Best regards.

Weird Android OS problem

Hello guys,
I have a problem with my Z3 for about 3 weeks now. After approx. 3 days without reboot, Android OS would just start to keep my phone awake equal to the time that the screen is off. So if for example Android OS is at Keep awake for 26m 35s and I turn my screen of and on after 5 minutes it would be at 31m 35s if you get what I mean. The phone is constantly active and does not go into deepsleep. Wakelock detector just came up with the Kernel doing **** in the background which doesn't really help... I've already done a factory reset which helped for ~ a week.
The funny thing about this is, that if I reboot the phone, Android OS keep awake changes to 0 seconds and stays there until I charge my phone again... This seems really odd to me...
Jumping from 6 hours or so to 0s just because of rebooting isn't normal..
Anyone can help ??

Android OS consumes my Mate's battery! Wakelock problem [screenshots].

Hi Guys!
I need your help. My Mate 8 (model NXT-L29 on custom ROM no. NXT-L29C432B192) makes me crazy because of battery drain. The problem is unknown for me. I've tried almost everything: turned off WiFi and BT scanning, turned off sync and backup of Google account, hard resets (via hidden menu). I even logged in via different e-mail - nothing has helped.
Generally I know only that it's connected with Android OS and Android System services - it shows me the default Huawei management app. Both of them can consume more than 1000 mAh of my battery! It's crazy! The phone is constantly awake.
I don't have root, but I decided to install Wakelook Detector [Litle] to access more sophisticated data. I assume that the problem is process PowerManagerService - just have a glance at provided screenshots. It's running more than 17 hours !
Please help me! I don't know what to do. My best SOT was 7,5 hours on WiFi without any hardcore apps like 3D games. In such conditions I should achieve circa 10 hours on Mate 8, but because of the battery drain it can't.
Thanks a lot and happy new year for all folks!

i had this problem a few days ago with the "adroid system" process. i unchecked almost all apps from autostart, and made only 2 exceptions (whatsapp and viber) for doze. And only 5 protected apps.
finally i rebooted my phone holding the volume up button, entering recovery mode. there i cleaned the cache and rebooted again. that fixed it for me.
My experience is, that the more protected and doze exceptions for apps you have, the more your phone get's unreliable.
