[Q] I need help establishing a wakelock please?

Hello all. I am writing about my wife's Note1 (N7000, 16Gb).
The phone functions just fine except for one thing. At about 50% battery, it will just go to deep sleep and will require a long press power to wake up. Happens with any battery and have tried a few different ROMs (custom and stock). A SECOND Note we have (my sister's; I have a Note2) doesnt do any of this with same batteries and same ROMs, so does seem to be weirdness with this one.
I DO have a solution which has been proven to work with a scientific cause/effect relationship:
I installed THIS app from the PlayStore:
https://play.google.com/store/apps/details?id=eu.thedarken.wl
Now I dont fully understand wakelocks, but I reckoned the CPU was going into deep sleep so I set the wakelock to be FULL (see screenshot 1). This 100% solves the problem and the phone is fully normal now, and my wife says she cant tell any loss of battery life.
SO....
Looking to do one of two things:
1. is there a way we can have this app AUTORUN on boot cos she keeps forgetting to run it when she swaps battery (which is once a day cos she is heavy outside house user) and then wakelock not running then phone sleeps! DOH! If autoruns, then she can at least SEE the wakelock screen and press the lock to be active (we are still testing how LOW a wakelock can we get away with but for now using 7)
2. even better, is there a KERNEL I can flash her to that will give me same functionality so she never even needs the app? Something where I can set a minimum CPU level in a similar fashion and it is now a set-it-and-forget-it even surviving a reboot?
See pic2 for the stock ROM she is on now and is great. Given that phone is otherwise fabulous and all else is stable and functional, I would like to keep to this ROM if at all possible so as not to introduce new weirdness. Also, given that this is such an easy software fix, I am not looking to hardware repair the phone as just want to fix this and get on with life.
Hope this is enough info for an informative and educational discussion and looking forward to some good advice.
Thanks to all, and kind regards,
Asif

So are you wanting to prevent the phone from going into deep sleep?

Correct, yes. Need to stop the phone from sleeping so deeply that it is effecttively off now as wife misses critical reminder alarms, as well as phone calls etc. As it is (without the wakelock) the phone is pretty useless. WAS actually my sister's but had to swap and now SHE has the wife's old one. Sister is a surgeon and when phone was deeply asleep, hospital could never contact her so not good. So swapped and sister has wife's good one so that is off my back. Wife's (sister's old one) is here and easier to test out as sister lives in England and I am in Glasgow. Easier to take dodgy one and work on it here.
So need phone to remain functional until such time as battery is dead, like you would expect any normal phone to do.
So need wakelock to remain in force as described above, as WITH the wakelock active, the phone is perfect.
Thanks.

Is the phone rooted?
If so you could flash this mod i made. It prevents deepsleep.

Looks like the kind of thing I need, thanks.
Was very much not keen on switching ROMs tho as this one just working perfectly, and we all know that every ROM has it's quirks. Didnt want more headaches with the wife giving me daily anecdotes of weirdness!
What do you reckon would happen if I were to try flashing this on LSO ROM? I suppose the worst thing is a bork and then I just wipe and reflash LSO fresh? Is this just a typical CWM zip?
Or is there anything just like this (kernel or mod) that could be flashed on LSO?
Appreciate your time and help so far.

The mod is in the androidpolicy.jar so i doubr it will work. Worth a try as long as you backup first

OK, thanks.
Before I do, will wait to let the thread cook a wee bit and see if any other alternatives emerge.

Bump.
Any other ideas before I try the above?
Thanks.

Just a follow up if anyone is following this.
I DID flash the LSZ ROM and the zip patch and phone still died that night and failed to ring the morning's wake up alarm. To be honest, I am not sure what is going on with it. I have done a 'deep clean' (actually too much and I bricked it and then recovered it! Code Brown!!) and now flashed Slim Bean 4.2.2 to try something totally different and get away from a Sammy based ROM.
We shall see by tomorrow if phone can sleep at night without going into a coma, and then wife's wake up alarm can still ring.
If not then I think it is time for a service.
But wanted to come back on here and thank you for your time and efforts anway.
Kind regards.

[Q] New HTC One Owner - Which ROM?

Hi All,
I've recently purchased the HTC One and flashed it with Android Revolution for 4.2.2
There are some small issues that I don't like with the phone which are:
- Camera isn't very good
- It gets warm often (even after browsing the web > 10mins)
- Volume steps are not to my liking (coming from IOS) - too large of a gap when hearing music
I've recently discovered ElementalX which has thermal options, maybe this will fix the warm phone issues? Anyone have experience with it working well with phone temps?
I'm not sure how to fix the camera, is there a ROM/Kernel that improves it?
There is a volume step fix out which doesn't do anything to the volume but increases the steps - so I guess there isn't a fix for this yet.
In conclusion, I think I've overloaded the phone trying different kernels (I like the HTC logo option to turn on/off) and I'm thinking of starting from scratch again. I want a near stock ROM e.g. Android Revolution - or should I just put stock on there (will root access still work on a stock rom if I've installed SuperUser ?)
Does ElementalX work on any ROM with 4.2.2?
What's the best ROM + Kernel for the things I want? Should I go back to stock + ElementalX? Will that work?
Hope someone can help, thanks!!

There are several Volume Step Mods in the Themes / Apps Section.
My personal Setup is ViperRom 2.1 with Elemental 3.4 Kernel but my Battery get on 42 Degrees so its not a heavy Problem when u can live with the temps
The Cam is a 4Ultrapixel so u dont get more then 4MP but u get 300% more Light on Night Shots...

If you want a rom like Android Revolution, why not go with Android Revolution? I'm using it with ElementalX.
The thermal options will make your phone run cooler, but it will impact performance somewhat. There are mods for the volume steps.
And for the camera, it's nothing without Zoe, so I'd recommend a Sense rom if you want at least somewhat nice pictures.
Edit: Grooov beat me to it

I've tried the volume mod but although the number of steps increases, the volume doesn't. So it acts like you don't have a mod to change the volume but just increase the number of steps (if that makes sense)
Did you get 42 degrees with the thermal option set? Is that under heavy load?
I can always see pixels (dots) on the camera which is why I said it isn't very good, maybe it works better outdoors. Isn't ViperRom heavily customised? I'll have a look anyway.

Your signature says you're using Stock! Anyway I was really just asking if it's worth installing Android Revolution if I can still get root access with the stock rom? Is that possible? Maybe I'll stick with Android Revolution.
Is there a way to remove these Kernels that I've added (can't remember which one I got) - should I just reflash Android Revolution without wipe? I don't want to lose stuff e.g. apps/contacts/bookmarks etc.
Do the thermal options slow the phone down? It is quite annoying at the moment that the phone decides to get warm whenever I start to use it, to do anything!
Thanks

ARHD contains a lot of optimizations, as mentioned in the thread. Reflashing a rom will also re-install the kernel (if it's included in the rom .zip). Seeing as you have root access, you can easily back up your apps using Titanium Backup, and you can sync the contacts + bookmarks with your Google account so they'll be automatically re-added. But as you're already on ARHD, it probably can't hurt to "dirty flash". Just make sure to make a backup in case anything goes south.
And you're right about my sig, I'll edit it now

ViperRom based on Stock Sense Rom with a bunch of Tweaks
and the 42 degrees are under heavy load like high performance games e.t.c.
greeetings
and the camera has greater pixels for more light thats the 300% light extra

Installed the new update to ARHD + ElementalX with thermal set to cool. It does seem to have cooled down slightly which is good! It's a bit early to tell if it really is cooling it down though.
The only issue I have now is that "Keep" keeps closing unexpectedly. I have disabled it for now. Anyone know why Keep keeps crashing and how to fix it?

Keep as in Google Keep? You could try to reïnstall it. All your notes are saved in the cloud, so you won't lose them.

Give Venom a whirl, just try not to be taken back by all the options, there are tonnes of them, i've got mine set up just how i like it, took me a while but it's spot on.

I tried a few ROMs before I landed on the stock Google Play Edition 4.3 Conversion. Loving it so far, it's very clean compared to both stock sense and the other ROMs that I tried.

Yea I gave GPE a go today and almost immediately missed sense, Nothing wrong with it, infact it looks great and performed well, I just missed sense.
HTC have done a great job this time round.
However I've got my eye on Paul's Modaco switch rom, which looks to tick all the boxes, only problem i can foresee is the inability to use custom rom's for the switch, I'm not a great fan of stock sense, I like colours and mods too much
Each to their own.

Thanks for the suggestions guys. I'm gonna stick with ARHD + ElementalX for now
I don't want to move away from sense otherwise I could have got a nexus 4 instead, and I like blinkfeed.
I tried a vid today and the phone didn't warm up that much,!! Maybe it's also because I used airplane mode and battery saver at the same time too.
Now I just gotta fix my other problems like find a better video player than vlc which seems to have some slight sync issues. Try to get my klipsch headphones to work better I.e. button controls and get this volume step issue sorted! Any suggestions for any of these?

Maximus HD 12.1.0 FTW
So far my favorite Rom. JB 4.3 with sense. Best of both worlds! Also has 4.1.2 speaker volume & can add CRT-off animation

Totally agree with you, Sense is beast (though I like CM and the likes too)!
I like MX Player for my videos and you can try Jays Headset Control for the headphones.

Thanks I'm using some headphones controller which works ok. Sometimes I have to double tap a million times before it works tho which is quite annoying. Setting speed to slower or faster doesn't help.
Using bsplayer for vids seems good no sync problems. So many roms to choose from! I'll stick with ARHD until 4.3 officially is supported by apps and released. This phone is slowly getting better thanks for your help all.
Another question... When I send a SMS and select a contact they appear more than once because its looking at the phone and SIM card at the same time. Is there a way to only look at the phone so I don't see duplicates?

Rooted Xperia SP 12.1.A.1.205. What next?

Hi,
Let me apologise first for posting this message but I really need help from this forum. I rooted my Xperia SP 12.1.A.1.205 using Towelroot & then installed SuperSU & gained complete root access.
I'm completely clueless regarding all this. I want to know what should I do next? I want to improve my phone's battery life and work on other features. How do I do it? This is the first time I rooted my phone. I have zero knowledge regarding this.
Please help me in improving my battery's life and let me know what should be my next step. Would be highly grateful if someone guides me.
Thanks!

You will have a glorious day experiencing new stuff if you search through Google. But no worries I will give you some head start suggestions.
I recommend Xposed Framework to be installed on your phone. Learn about it here. With it you can now modify your ROM to be as best as possible as per to your need. Some module recommendations, you can use GravityBox to modify some nice visual appearances on your ROM. You might also use GEM Xperia Xposed to advancedly modify your Xperia home screen. You will also find YourTube interesting as it allows you to change how the YouTube app behaves.
Battery saving is a lot better with Xposed installed. By using Greenify you can hibernate RAM hogging plus battery killing app. Also with Amplify you can drastically reduce battery draining caused by Google services.
Last but not least, you may also experience the bigger picture, by installing recovery and flash a new ROM on your phone (but this is a practise that requires accuracy when doing it). Think about KitKat, you can have it on your phone by selecting one of many wonderful ROMs built by wonderful Xperia SP developers.
I hope you can get some pictures with this post.
ROM = Firmware = Operating System
Flash = Push files into the higher level file system

Hi!
Thanks a lot for taking out time and replying to my query. So you're saying that I should first install Xposed Framework? I don't want any fancy looking theme or design for my SP. I just want a simple layout. My only concern is to improve my battery's life. Nothing else
So should I only install Xposed Framework and then install Amplify? Will this much do?
Thanks a lot once again!

Hi again,
I installed Xpose Framework successfully and Amplify. I even bought Amplify pro version. I don't think my battery life has improved. I guess the battery is discharging faster than it used to. Can you please guide me in helping this problem? Without WiFi, I love 1% charge in 5 minutes that too in flight mode. If I go through the menu for some time, I lose battery.
I successfully rooted, installed Xpose and Amplify. Please help me!
Thanks!

Installing it only without customising won't help! Take your time to learn the app. Additionally, Amplify doesnt drain more battery on my device. Perhaps something else is? Amplify does not do anything if you haven't modify anything, plus, even if it runs, it uses the system process, which extremely cut-down battery sucking that normally happen with solo processes.

Hey,
Thanks a lot for replying! How do I know which services/alarm to stop in Amplify?

I read few queries in some forums regarding the battery problem and most of the people suggested to upgrade the kernel or something of that sort. Can you please let me know if I should tune my kernel to improve my battery's life and if yes, how should I go about it?
Thanks!

You don't "stop" them but you "limit" them. The two terms are very different. I am using a different ROM so I cannot suggest a common things for my ROM, but these are standard among devices as they are included with play services:
Wakelocks
NlpWakeLock
SyncLoopWakeLock
NlpCollectorWakeLock
Alarms
com.google.android.gms.nlp.ALARM_WAKEUP_LOCATOR
com.google.android.gms.nlp.ALARM_WAKEUP_ACTIVITY_DETECTION
Services
This feature is new, and there's currently no known safe services to be limited with Amplify

Sorry since you're using stock ROM, kernel modifications are way too limited.

Hello again,
Thank you so much once again for replying. Ok, I get it.
So if I change my stock ROM to some other ROM, will I be able to modify the kernel then? Can you tell me if I should change my ROM..if yes, then can you suggest me how I do it?
You're awesome! God bless you

Ok, this is really annoying. My battery is creating problem for me. I fully charged my phone, and it's been almost 5 hours and I have lost 5% charge that too in flight mode with almost all the services turned off. The display was turned on for 10 minutes only. That's it. Can you please help me in solving this problem?
I have read almost everywhere where people keep their phones in flight mode and they don't even lose 1% after 8-10 hours.
What should I do?
Thanks a lot!

Thanks However, this is not an easy process. You should know too that risk of your phone being damaged is quite moderate when performing these tasks. I can't tell you if you should, as it should be completely based on your requirements only. Decide for yourself and try the ROMs for yourself. I may guide you, but this will give you plenty of new questions. And since you are new to android, there are many things that are unknown to you. But these things are well documented / answered if you use the search feature of the forum and Google. Only ask for something that is unique enough.

Sorry, I can't help about this bug in stock ROM. Another person faces this problem as well but unfortunately there are no fix. Alternatively, you can save your battery by changing network mode to GSM only.

Thank you so much for replying. I am willing to take the risk. Can you tell me how I should begin upgrading my ROM? I will use the forum in case I face any problem. I just need some one to guide me.
My cell stays in flight mode and I don't even use it. I lose 1% every hour even if my phone enters into deep sleep with only 1% awake time. What is wrong?

I might take my phone to the Sony service centre for a check up. Can you please tell me how do I unroot my phone? I used Towelroot to root my phone and then installed Xposed Framework. How do I make it go back to the original state?
Thanks!

To uninstall Xposed, open the Xposed Installer, select "Framework" and then hit the "Uninstall" button. What root application did you installed? Is it SuperSU? If so, you can easily unroot it by searching through its settings.. I am sorry I can't pinpoint to the exact location.

Battery Drain...
The battery drain your getting is probably due to alarm service/google play services/android os. I have the same issue, stock .205 clean and rooted, whenever the alarm is on I get horrible battery drain what makes it worse is that the android os uses excess mobile data which causes the battery drain. I think the alarm has something to do with google play services. There is no problem when the alarm is off, but I need it so cannot turn it off.
It is a very annoying issue that I haven't been able to fix, these running services prevent the device from going into deep sleep hence the battery drain, I typically lose between 23%-30% over night at a rate of ~3% per hour. :crying:
This probably doesn't help your situation but at least your not the only one.

Thanks a lot for replying. Thank you Shin; but my Xperia SP enters into deep sleep mode 99%.

I'm extremely irritated now! I changed my phone and got a new one but still there is battery drain. I rooted it, installed Xposed Framework, installed Greenify (Donation), disabled almost all the useless services yet I lose almost 2% charge every hour that too in flight mode without even touching my phone!
What is wrong with Xperia SP? Can anyone please help me in solving this problem? Please?

Bro, there is nothing wrong with the phone, as I said above it is to do with the software, from my experience the stock based eXistenZ ROM does not have battery drain but still has **** RAM, you might want to give it a try.

Hi,
Thanks for replying! Can you please tell me how do I install it? I have no idea how to do it. What about the RAM problem? Will it slow down my phone?

Here is the thread. Installing is easy, use the locked bootloader version, instructions are provided. In the instructions it says you should be on the 4.1.2 firmware but being on the latest 4.3 firmware is ok. To put it simply all you need to do is download the ROM, root your device (towel root), install superuser (apk), install cwm recovery via windows, flash ROM. If you need more help get back to me.
As for the RAM, it is still a problem even on eXistenZ, I believe it affects all stock ROM/kernel variants. From my experience the device still runs smoothly it is just that there is less free RAM available so the home launcher commonly closes when heavy apps/several apps are opened but it then reopens when returned to.

Looking for the BEST 5.1.1 Rom (as of 3/1/2015)

Hi everyone,
I'm planning to reflash my device with another lollipop rom. I'm currently (and have always been since its release) on AICP. But I'm fed up with the freezes and such
Is there a better, faster (battery friendly) lollipop rom than AICP? Or are all the roms kinda the same? (like everyone has a lot of freezes)
I thought about temasek (since it fully supports the fast f2fs), candy5 but also all those new sabermod roms which i do not know a lot of.
What do you think? Have you tried other roms? What is your experience?
Thank you!
PS: How's flashing XPOSED? I'm using it also on AICP 22/10. Is it safe to use or is it actual one of the reasons behind the freezes? Cause I use xposed for greenify and Superusermod which I need for some sony apps

Is it just me or what
Every 5.1 rom on my sp are horrible lag
Battery life are terrible
"quick boot " take 2mins to turn on my phone
I prefer stock 4.3 or 4.4

Try temasek with t-kernel, i use this rom almost month and it's good, almost none freezes, but this system got 2 annoying bugs:
- Long boot
- Bluetooth don't remember saved device, you need pair every time
I think xposed causes problem with freezes so i don't use them now.

"quick boot " take 2mins to turn on my phone
This is not even possible.
I think you might've understood the meaning of quickboot wrong.
Quickboot doesn't mean a reboot would be fast.
When you enable quickboot and "SHUT DOWN" your phone, you'd go into a state of hibernation.
And when you power it back on, it starts up within 3 seconds
I have never even got it crossing 5 seconds. Ever!

Is battery life same with temasek? Or does it wear down quicker? Also how do you use apps like greenify and superusermod then?

I use greenify pro without xposed, superusermod i add manually, about battery life it's good ( i think like other LP roms) Today new version up i start downloading now

Yeah already downloaded! And alright then. And sorry I didn't mean temasek I meant tangerine kernel Goes battery life quicker down and does it have better performance or only a little?

Didn't test too much with stock kernel, in new version oftemasek is new kernel so i now check it

CPU small cores do not stop, big cores not working

So, my issue is as the title shows.
The A53 cores do not stop, and A57 cores only work like 0-1 core at a time, usually doing nothing.
Which causes my phone to be heating up whenever it isn't sleeping, sometimes drains battery even when charging at 2A.
I'm using E6533(dual sim version), and it happened when I updated my phone to 7.1.1(32.4.A.0.160) from 7.0.0(32.3.A.2.33) firmware with flashtool.
Yes, I've rooted my phone, but just for removing shutter sounds.
I tried to rollback to my TWRP backup, factory reset, rollback to 32.2.A.0.305, using custom ROM(lineage), quite everything I know, but nothing worked.
Does anyone have a clue of what might be the problem, and what might work?
Thank you.

I was using stock ROM, but while trying to fix the issue, I've tried custom ROM too. Though nothing has changed…

Well, if that's normal, this shouldn't be an issue. Though I do wonder where's the big little concept gone.

Did it ever occur to you guys that it might be dynamic hotplugging and a specific configuration/setup is being used ?
Or is it in your case really being buggy and broken ?
You left something working in the background and monitored how the cores behaved ?
Using different apps ? (say: kernel adiutor [or kernel adiutor mod], EX Kernel Manager, CPU Z, etc.)

My situation has improved, so I'll update my situation, hopefully it'll help someone.
After updating to stock 7.1.1(without modifications), my phone got just very hot while the screen was on., consuming more than 2A.
Rolling back did solve the problem(becomes normal heat), but as for me, I chose to use lineage OS, which was great. The only drawback I'm having now is that the camera button's function isn't as versatile as the stock ROM, especially while opening the camera app from sleep state, is a bit unstable.
A great thanks for all of you guys for giving me advices.
