seems next to impossible

Hi ! Even I am trying to do the same. But till date, tried many solutions from XDA. But none of them are working.
[HTC Desire 500] jmcclue:
The above method works, i done it..
[HTC Desire 500] JPSBhullar:
Didn't work

Even this method doesn't work. First thing in thread only Single Sim Firmware and ROM are provided Whereas I have got Dual Sim Phone.

I was able to get Dual Sim ROM from another thread. But was not able to get firmware.

Firstly, this should be have been posted in the Q & A thread, not general..

And secondly, want to rephrase your question so its understandable. What do you mean by your screen slipping? ;)

[Sony Xperia L] ishan_rulz:
I am on 15.A.3.1.14

I tried the SomcPhone.apk fix and managed to soft brick my phone trying to get the network to work. I had to flash the ROM again and it was a pain in the arse.

Is there a reliable way to fix the proximity sensor? IT SUCKS! Also, I want something permanent. Not "call someone and hang up"?

Thanks a lot!

If flashing a KK ROM is an alternative, then ok but is the battery life and everything on KK fine?
[Sony Xperia L] :
Proximity sensor on 15.3.A.1.14 should work normally. Try wiping data of SemcPhone or a factory reset.

I have searched all over multiple forums and havn't come up with a definitive answer to my question. I have a Cingular 8125 and no data plan. I want to disable GPRS so that in case my wifi isnt connected I dont connect through GPRS. There were rumors of a registry key that could disable it, but I couldn't find any more info.

Where can I find the registry key to disable GPRS entirely?
[8125, K-JAM, P4300, MDA Vario General] masr1979:
What I would recommend is for you to install Registrywizard it has the option to disable GPRS, or look a bit harder since I'm pretty sure the info is around here somewhere, you might even check in registrywizard's thread, it's a long one though, so be warned the thread is this one

[8125, K-JAM, P4300, MDA Vario General] kaffine:
Super, Thanks!

The keys for disabling GPRS is actually in HKLM\Comm\ConnMgr\Providers\{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections\ Cingular GPRS\

and the same except the last part is Cingular CSD.

Thanks again for the tip.
[8125, K-JAM, P4300, MDA Vario General] unvjarhead:
Cingular

I know this isn't the answer you were looking for...but I just called Cingular support (611) and told them to disable GPRS (might be best to call it mobile internet...they aren't the smartest). They will disable it immediately and you don't have to remember which keys you changed if you want to enable it later.
[Shield Tablet General] sk8ordie0:
Who is having issues with battery here? Android OS is killing my juice! I have gotten fed up and rooted my sheild and frozen most everything possible to try and get the OS down. I will lose like 30-40% overnight. I was thinking it was the shield or nvidia services tied into the android OS but that doesn't seem to be it. Blake_wavelock seems to have a lot of the activity and deep sleep isn't Happing as it should. I haven't tried WiFi off when screen is off and I'm going to use that tonight. I have all the location setting and Google setting inactive. I'm using optimized for battery.

Let me know what you think. I come from a posse of Samsung devices and get great battery life on them.(of course they are all rooted and ROM)

Screenies
[Shield Tablet General] Keithn:
Have not seen that. Do you have a shield controller connected? I believe that blake is related to the controller.
[Shield Tablet General] sk8ordie0:
I don't. I actually have frozen most all the gaming processes. So far looks like it doesn't like the WiFi and having WiFi off when screen is off seems to be working. I'm going to keep tracking the battery cycle and see. Will repot back. Thanks for chiming in!
[Shield Tablet General] Project:Frankenphone:
I am running stock Android OS and I can run a full day on it with a single charge. Though I don't use the internet on it much and other services other than texting and calling. I lose about 10-20% over night.
[Shield Tablet General] bleached45:
Have you checked under WiFi advanced settings for keeping WiFi off while screen off and WiFi optimization? (Sorry if these settings aren't there, looking at settings on my phone, as I don't have this tablet, but I am considering purchasing one).

Also, is your WiFi signal poor or strong? Because that plays a big role.
[Shield Tablet General] JogeTheMan:
I have this happening with airplane mode on. Only seems to happen when I'm home though.

Weird.
[Shield Tablet General] sk8ordie0:
Check out today. But haven't been wondering around apps and such. Lol

Yesterday all was well til I messed around on chrome and a few other apps before bed. I was pretty sure I had skinned the cat until I woke up with 2% battery life and it was 35% before bed.:eek::eek::eek::banghead:
[Shield Tablet General] markymark567:
Those with bad battery life should check what apps they have installed and use wakelock to find out what's keeping your tab awake over night. I have had many android devices and unusual battery life like many of you report is virtually always due to a user installed app or combo of apps. I get 3 days use on one charge MINIMUM. This is with WiFi on 24/7, and I use it for homework for several hours a day and some light gaming thru console mode (maybe an hour a day). I use a custom power mode with 50% cpu clock, 2 cores and 30 fps. I never take it off this power mode cuz I never see any difference in performance. Il post pics from next cycle.
[Shield Tablet General] aamir123:
Yea I'm not seeing bad standby either, battery overall isn't great but OK. I get about 5 hours screen on but most of my usage is android games.
[Shield Tablet General] sk8ordie0:
I guess all the hard work of freezing off apps has paid off. This is the type of sleep I'm use to!
[Shield Tablet General] aamir123:
75% left with only 10m screen on? That's not good...
[Shield Tablet General] sk8ordie0:
More than that ....
[Shield Tablet General] aamir123:
That's more like it, still not what I call good but for something that offers everything I guess it's OK. Still wish I had a way of reaching 10 h screen on.
[Shield Tablet General] jimmyhauser:
Twice now, I have gone from 70-80% to dead in just a few hours with the screen off. I have a few background apps with push notification (facebook, appy geek, mighty text) but they are all the same apps as on my oneplus one, and it only drains 1-2% per hour. Same with my Xperia Z Ultra (which I had set up as a tablet, no sim installed)
[Shield Tablet General] sk8ordie0:
Go very dim and freeze everything and im sure you could get close! I do use greenify. I like app opps but to lazy to set it up.

I have the tegra note 7 and this shield. I pretty much just got both about a month ago. I have figured out that the WiFi hardware is not as good as most phones. So it will cause a wavelock and drain the device (which is labeled under android OS). So make sure under settings<wifi<advanced you choose WiFi off when screen is off or only when plugged and not to search for WiFi networks if you don't need. I have also seen that if you root then you can use titanium backup or whatever you like to freeze all the apps that cause harm or excessive battery drain. Also, with root you can use app called wavelock detector to figure out what app is draining you down. I have just about everything frozen except for updates and a couple other services. Good luck report back on what's causing it if you can. Blakewavelock got me, lol.

Here is this cycle from yesterday (still going) What wavelock detector looks like

More of this cycle
[Shield Tablet General] ballfire:
and i thought i was the only one getting frustrated with the tablet not going into deep sleep

-sometimes wakelocks is blake_wakelock

-other times its AudioIn

-or google search

no idea why its stopping the tablet going into deep sleep. but it's fking annoying

tried airplane mode , didnt help.

also tried wifi on always vs only when plugged in.. also no difference
[Shield Tablet General] sk8ordie0:
Are you rooted? As you see what I have went through. I can help you brotha.
[Shield Tablet General] sk8ordie0:
Still going!
[Shield Tablet General] aamir123:
Screen on time matters most. I got about 3 days 5 hours mostly from gaming
[Shield Tablet General] ballfire:
I'm rooted. what can I do ?
[Shield Tablet General] sk8ordie0:
Install titanium back pro if you don't already have it. This will allow you to freeze apps. Basically you will need to see what all you use and don't use for your freezing process. I can tell you that I'm only running minimal nvidia and shield services and I have a feeling that's where it comes from. Have you selected the option to turn WiFi on when screen is off? If not, do so. Here is the screenies of what I have frozen. Do this then reboot and also install wavelock detector and let it run.

Note: you may use some of these apps or services. I don't! Check pm also..
[Shield Tablet General] sk8ordie0:
This is how I'm looking now. (Same cycle)
[Shield Tablet General] ballfire:
thanks for advice will try a few things to see if that works
[Shield Tablet General] minieod:
all: this is happening on what seems to be the CM chain of roms.

install xposed installer, install wakelock detector, block google services, with a filter for "connectivityservice"

should be good to go. fixed it for me.
[Shield Tablet General] An Droid:
I've had the same experience.

Tried a few things without success (disabling Wi-Fi during sleep, disabling/fully enabling Location services, disabling Google sync options).

However, the last change I've made appears to have helped the most - disable Wi-Fi Optimization (in the advanced Wi-Fi settings) that's supposed to help battery life, ironically. I've also disabled "Scanning always available."

I've also gone back and set my Wi-Fi to always on as well (kind of pointless to disable this if I want email, etc. picked up on a Wi-Fi only device). My location settings are also set back to Battery Saving mode well.
[Shield Tablet General] sk8ordie0:
Maybe invidia will send out a kernel update eventually........ Don't hold your breathe! Lol

One request: Please make the images links instead of inline images. This page has WAY too many images now.

I've seen behavior like what the OP indicated once before. Unfortunately I wasn't near a PC so I couldn't save a dmesg.

Diagnosing something like that requires either BetterBatteryStats to show kernel wakelock stats, or a dmesg to see if the device is suspend thrashing. (The stuff I saw in the Battery screen kinda looked like what suspend thrashing on the Find 7 looked like back when we had a kernel bug in our charger drivers... Obviously the root cause on the ST will be something completely different, but if you see that the device is not sleeping but the "awake" bar in the Battery screen is not lit solid, the device is probably suspendthrashing.)
[Shield Tablet General] An Droid:
Nevermind...My Android OS drain returned today.. :(

Off the charger at 100% this morning, unit untouched all day until this evening and I've got a 60% drop.
[Shield Tablet General] crazyjc81:
I had the same issue.

And then I rooted, installed xposed framework and the Unbounce module(blocks wakelocks).

Plus i've set wifi to turn off when the tab sleeps(in the wifi advanced settings)

Been 2 days since I charged now. A few hours of gaming and browsing everyday.

Usage has been light so this isnt your average battery lasting scenario.

This is just to say that my tab's battery drain when sitting idle has been drastically reduced with the above steps !

(Will post a screenshot when I get back home)
[Shield Tablet General] Shaky156:
Someone enable usb debugging and pm me a kernel log and os log from a fresh boot
[Shield Tablet General] tooshea45:
I noticed the biggest thing is to turn down the throttle of the CPU and the frame rates down to 20.

Right now I'm running @ 50% power and frame rate is set to 20.

I run multi programs all day long and the thing that kills the battery the most is Waze the other programs don't seem to matter much.

I need to have the tablet plugged in or Waze will kill the battery in about 3 hours.

Other than that this thing is great I barely run any games on it it's mostly for multitasking I wish we could get multi/split screen working.
[Shield Tablet General] sk8ordie0:
Did you have WiFi set to always off when screen is off? If not, most likely its that. I have been having a issue getting that option to stick. It shows it as my setting but I sometimes catch it still on when wake the screen. (After several minutes)
[Shield Tablet General] An Droid:
No.

When I first came across the problem, turning Wi-Fi off during sleep was one of the first suggested options I tried - I found that it made no difference.

Personally, as a Wi-Fi only device, I find it pointless to do disable Wi-Fi if I want background email sync, notifications, etc. to work.

However, on closer inspection, I found that my Location settings had somehow reverted to off after experiencing the drain above. Having previously tried different settings here as well (as suggested) and finding no change to the Android OS battery drain, I had set this to the Battery Saving mode when I had the good results. I've set it back to Battery Saving mode and had good results today (no Android OS drain).

We'll see what happens..

Iv followed this thread but am still unable to stop mediaservice from running, it constantly runs in the background despite disabling everything I can.

I even checked the camera app and removed any images.

is there anyway to say what exactly its doing?
[Shield Tablet General] sk8ordie0:
You have a SD card in? Sounds like a corrupt SD card or maybe eject it , reboot , then put it back in and see if that helps.
[Shield Tablet General] nielo360:
I did not have an SD card in there, but Iv figured out it was the Gallery app(despite being empty), once I disabled it mediaservice went down to 3% but Im unable to make it stop. Does it always keep running in the background? Iv disabled live wallpaers etc too.
[Shield Tablet General] mozza54:
I picked up the LTE model last week and while as a tablet its pretty decent, I'm having a nightmare with the battery and Wifi on this. The wifi connections rubbish (but I'll save that for another thread) but I get about 13 - 14 hours on a single charge. That might not seem terrible but I use my tablet for about 2 hours of video and maybe the same for miscellaneous browsing and it just seems to drain.

The one thing that does happen every time I charge the tablet, I'll take it off at 100% and within about 30 minutes, its down to 95% weather I'm doing anything or not. Considering Im coming from an iPad that could get me through a couple of days easy on a single charge, this isnt boding well for the Sheild.
[Shield Tablet General] whoamanwtf:
I don't have any idle battery drain issues, that's with only 20 minutes screen usage.
[Shield Tablet General] lanwarrior:
Ah, thank you for letting me know about that. I almost pull the trigger on getting the LTE model, but it seems Nvidia ignored.. sorry... has not fixed the Wifi issue.

FYI, there are tons of posting in here and at Geo Forum about crappy Wifi connection. I returned my Wifi version because of this.
[Shield Tablet General] Shaky156:
If you have fast draining wifi, install a battery monitoring app so developers can diagnose the issue, posting screenshots of androids stock battery monitor will not help.

My batterys fine, no draining here

[Shield Tablet General] Shaky156:
I should rephrase that, I meant I am looking into what people claim to be a wi-fi issue? Wi-Fi works fine for me but checking if I can make it faster
[Shield Tablet General] CM17X:
I read it, but your solution is not fancy, is almost brute force. If you freeze the shield wireless controller service you'll ended up unable to use the control for games. As long I have it, I need it running. Can't figure out how to keep it calm when not using the controller.

It's Wifi being unstable. I.e. can connect, have network activity, then stopped. Have to wait or reboot to get it back. It's posted in XDA and Geo Force forum, but seems to affect only some batch of the tablet.
[Shield Tablet General] Shaky156:
if someone with a tablet that produces that error, logs and tests wi-fi and provides a log, I can take a look into it, but as far as I'm aware its working perfectly fine for me.
[Shield Tablet General] sk8ordie0:
I understand totally. My fix is for me.

Produce the logs needed for Shady and he might be able to hook you up. I don't game much.

This makes sense. I must be one of those because that is what mine does here and there. I wonder if the update has fixed the issue or if I need a RMA ?

[Shield Tablet General] mushikipt:
I think its more than one prob that drains battery, i am also for some time trying to discover the problem(s)

My first suspicion its the location service

i was searching around the web and i saw this thread and i tough i would post some pics of the battery stats before and after i turn of location service in "battery saving mode", but then this happened

[tinyurl.com/q24r3cg

My tablet was all ok and trendy with 92% and 8 hours standby, and the ONLY SINGLE I DID after 11 hours, was to enable location (on) with "battery saving" option and take a screenshot!

8 hours later bang., battery's gone with some weird stats to show for (it wasnt charging ofc)

I had for some time ".nomedia" files in the tablet one in the root of the microsSD (lots of manga there) and some in some misc folders in the shield main drive "android; download; etc; obb; data"

Now i have placed one ".nomedia" file in the root of the shield drive and disabled the default camera app (installed the google camera) to test.

bottom line i wanted to test the location "battery saving" mode battery drain, because im almost sure it also something wrong with it but i also found this problem, i think its also related with some jpg corrupt files the main camera app creates, not sure.

Tomorrow i will post some screens after and before the location "battery saving" mode enabled and hope taking a screenshot will not drain my battery again :)

edit: nvm i was wrong.. the location service impact on battery wasnt significant :\
[Shield Tablet General] sk8ordie0:
App Ops [Root] by droid mate in playstore. I turned off all services in chrome, play services, google. Just remember if you get a FC its prob from something you turned off. Not that I have that issue just saying'. Good luck and hope it helps.
[Shield Tablet General] ballfire:
tried app ops and turned off services in chrome and playstore but battery still plummeted with screen off because tablet never went into deep sleep. idled at 1ghz! updated to lollipop now much better battery life. tablet deep sleeps properly. idled 24hrs didn't even drop 1% manage screen on time ~7-8hrs. really happy with lollipop from battery perspective
[Shield Tablet General] CM17X:
Wait a minute. What options are you using on your tablet in order to get 8 hours of screen (I guess you're not playing but reading, etc). What processor mode or anyway. I wish you could elaborate it.
[Shield Tablet General] ballfire:
this is pretty much default after i updated lollipop

bt off

wifi on

gps on

prism backlight on

cpu optimized

auto screen brightness

just surfing net on wifi with chrome,flipboard,no gaming,reading a book ( coolreader)

before with kit kat i would get about 5hrs screen on and it would be dead. mainly because stupid blake wakelock problem. now i get ~7.5 hrs screen on
[Shield Tablet General] CM17X:
And when you hit the 7.5 hours on screen, how much battery is left?
[Shield Tablet General] ballfire:
only 3-5%by that stage
