app that turns off data on screen lock?

Hey all,
I tried searching but came up empty, is there an app that specifically turns off data when you turn your screen off or lock the phone? I read that juicedefender does this but was wondering if there was a app that is designed to turn off certain things when locking phone.
thanks!

Well you basically said it...you can use juice defender, or look into the tasker app.

Juice Defender ftw

I've been looking into this same issue. After looking around and getting some advice from another xda member, I went with juice defender which has been outstanding so far.
If you heavy, heavy usage, you won't really notice a difference. However, if you use your phone, set it down for a while, use it again, let it sleep... all throughout the day, you will notice a significant increase in battery life. The first day I installed it, I sent a text while I was at work and then set my phone down. I grabbed it almost 3 hours later for something and it had gone down 1%.

While JuiceDefender IS designed to save battery life and such, it is designed to do just that. Meaning in order to save battery life, it disables and enables certain connections when the screen is off/locked etc.

I totally agree with you on the type of usage. If your screen is constantly on you probably won't notice a difference. Juice Defender saves battery when your phone is inactive.

doesnt the evo already have a disable always on mobile data option?

If you're on Sense, there's a widget for it. On MIUI, it's in the pull down bar toggles

Sorry to be a very late reply, but...
Does JuiceDefender turn off Mobile Data while wifi is connected?
I only ask because i have installed it, and it doesn't seem to be doing this for me.
Seems odd, because i don't need Mobile Data on while wifi is on.

Well if it doesn't do it jus go into connection settings and turn it off or if the ROM your running has quick settings in the pull down see if mobile network is there if it is just uninstall juice defender and make it a routine to click that before you put your phone down or in your pocket

Android system draining battery

The android system is draining my battery pretty badly. It's taking about 25 percent of my battery. I have my Gsiff_daemon deleted, but it's still taking quite a lot of my battery. My phone would go down 1 percent every 5 mins in sleep mode. Is this normal and how can I decrease the battery usage of android system? I'm on 4.0.4 stock rooted.

When you have battery issues you need to post a battery info screenshot. Showing your battery use and what is using it. It will help Diagnose the issue.
IMO (I am not pro) I would think being on stock you should have no problem although you are rooted so I think. Its either a hardware issue or something you did. How did you root your phone? if you followed a Tutorial what tutorial did you use?
What i would do is first charge the phone to 100% then let it drain to around 5% and post a screenshot of your battery usage, I would also post a History Screenshot too.
After you have done that you can patiently wait as i bet someone more knowledgeable than I will post something about your issue.
Although Since your rooted you could Install a New Kernel that is made for battery life. That should help if your ROM is not the suspect (I think it could be) Next I would also flash a good stock based rom (that is if you like and want stock based). Pimp My Rom also Has some Battery Saving Tweeks in it if you wish to not flash a ROM try PMR to tweak your system.

I didn't really cared about my battery life before since I always have extra carried with me at all times. But my power is out because of hurricane sandy and I have no idea when will the power be back up. Now every percent battery counts since I won't be able to charge. I'll try to put screen shots up but I only have my phone because my laptop battery died already.

Go into your battery screen and tap on Android System and then scroll down. it will show you all the processes that are associated with that particular facet of the ROM/Battery. In there, you can see what is being used by Android System and hopefully something will spark your eye. Do you have an Alarm/Clock setting, Calendar, media scanning,...? You can force close the offender.
Also you can go into Developer Options and tick Show CPU and it will show an overlay on your homescreen that will show real-time CPU usage.

I turned on cpu usage in the devekoper options and I see that x.xx/x.xx/x.xx (x are numbers I can't track them down because they're constantly changing) are always on the top and takes up quite a lot of cpu. Is that something I need to worry about?
Sent from my SGH-T999 using Tapatalk 2

I would reboot and once it is back up and running, go to Settings>Apps>Running and FC everything that you are not using. Then switched to Cached and FC everything that populated over from running and anything else that you don't need.
When I say need, I understand that you are in the danger zone and w/o power. You don't need Facebook, MediaHub, Music/Video,...Not that those are specific to you, but if you only have one battery left with no power in the future, then I suggest going bare bones for the time beaing.
***************
Sidenote: I was just reading about some things and see that some people in NYC are using Hotels/Gas Stations/ Stores that still have power to charge up the cell phones. Not sure where you are but might be worth looking into. How many times have you gone into that corner store? Do they recognize you? Maybe they could share some power. See where I am going with this?
Be safe

I had "Android System" eating my battery too. I'm stock/rooted. I had Cerberus installed briefly, uninstalled - about when my phone started being hot (bottom third) when sleeping in my pocket. Drove me nuts - sorry, but I simply cant tolerate an IDLE phone getting hot in my pocket! Anyway, I rebooted the phone, turned it off, pulled the battery, installed Better Battery Stats - eventually the phone stopped having massive drainage from "Android System" and now it's not hot anymore whether it's on browsing the web or idle.
I guess there are two points to my post 1) the way I could tell my problem was fixed was the phone stopped getting hot -and- 2) the problem hasn't come back for me after a simple fix of multiple-power cycles. I've seen mixed results with a fair number of people saying that rebooting their phone fixed there problem and about an equal number saying the problem either wasn't fixed by rebooting or it came back again later.
If it happened to me again I would open a Terminal and run the "top" command and just keep watching it until I figured out what was eating up my battery (CPU time).
EDIT: Oh - and to confuse things more I used Titanium Backup (pro) to freeze/un-install some of the T-mobile bloatware in addition to setting email to sync slightly less often...

I have my power back on and factory reset my phone. I see android system had already taken 30% of my battery after about an hour of use. There is close to nothing on my phone since it just got factory reset. I don't even know what to do anymore, I really don't want this "android system" sucking so much of my battery.

Id suggest flashing the full stock fw via Odin. Possibly something got corrupted during an update maybe.
I saw uou used Show cpu usage earlier. Don't worry bout the numbers, but watch for the processes that seem to stay at the top and let us know which they are.
You can get the fw from my thread here.

The cpu usage is very high I think it constantly stays at 1.2+ 2+ 4+. It can go as high as 9. I'll try flashing stock rom again and see how that goes later today.

Ok, but beneath those numbers you should see the list of processes. Theyll be constantly changing but you should be able to pick out which ones seem to stay at the top.

The only thing below the cpu usage is the system_server. Android system is only hogging 11% of my battery today. I don't know why was it at 30% yesterday but it seems normal now.

Verizon took out Battery Saver, here's Qualcomm's solution: Snapdragon™ BatteryGuru

I, and a few other users have noticed that Verizon decided to have HTC strip out their battery saver toggle on the Sense ROM (4.2.2) that ships on VZW's One.
Luckily, Qualcomm provides a standalone application which covers 90% of what the toggle does.
Snapdragon™ BatteryGuru
https://play.google.com/store/apps/developer?id=Xiam+Technologies+Limited,+a+Qualcomm+company
(personally, I haven't found the need to use it yet, but I figured it would help some people)

Thanks man, I was looking for that battery saver mode everywhere, but I guess this will do as well.

Thanks for this info. Anyone know if this is particular app will perform better from more generic battery extenders like Juice Defender?

According to the reviews all it does schedule syncing. Don't know how that is going to save battery...

Battery saver apps are a joke. The only thing I liked about power saver mode was that it cut the CPU frequency down and cut data off after a certain period of time. Other than that, if you need to save more just turn your brightness down, turn off bluetooth, use WiFi as much as possible, and use the phone less.

1+ lol

I normally agree - I realized the other day though, that I don't need background *push* email - but I'd like to have my phone "fetch" email every time I wake it up. Anyone know of anything like that?
(there is a manual setting, but it is when you *enter* the mail app, I'd like it to fetch every time I use the phone.)

Think about how often you "actually" need to have your emails and set it to that. For me, my Yahoo emails I don't need it to check but once hourly. But Gmail is push automatically so I won't mess with that. My corporate email defaulted to push but I often don't need it to constantly update and annoy me so I'm contemplating on 30 min intervals. Setting your emails to longer intervals should reduce that "email stress" that most people seem to endure these days.

The app has low power mode controls.
You can turn off mobile data during inactivity.
Some other features.
It basically gives you battery saver control on any Snapdragon based device.

Lol you could always just use BoneStock ROM. Andy threw the battery saver apk from (can't remember dev's handle. sorry) back in it.

It limits CPU, dims display and disables vibration feedback. Basically everything you can do yourself in stock and if you have a CPU app like SetCPU. Just a one click option that Verizon took out bc they hate battery life I guess idk.

Im running bonestock now, and the power saver has increased my battery life fairly significantly, i'll take that, because at first i wasnt impressed with the battery life, and i watched the ifixit tutorial on how to tear this phone apart to replace a battery, and i want nothing to do with that

Standby Drain Problem - can't find the reason

Hey guys,
i recently got a HTC 10 cause Ive dropped my Galaxy S7 in water. (insurance)
Besides that the HTC is noticeable faster, the standby drain drives me crazy.
HTC 10 @ Viper ROM with elementalX Kernel
1) What the hell is "BatteryServiceUpdateStats_3"? in 16 hours, it causes over 600 wakelocks per hour. Maybe this is my draining problem? In the Battery Historian screenshot you can see, that my phone is constantly doing something because of this process.
2) Why is there an "unknown" entry at "Kernel Wakeup Reasons"? 287 per hour... wtf?
3) In GSam you can see, that "Android OS (Kernel)" is (always) the top process...

Thankyou in advance, i can't find more tools to analyze this strange behaviour....
Edit: so i checked Battery Historian with active/inactive WiFi... and what do I see? Yep, much less wakeups from BatteryServiceUpdateStats3 & generally less Wakelock time..... why???

You might have this problem. I have it too and it's infuriating. I've pretty much stopped using WiFi unless I'm charging. Really spoiled my experience with this phone.

Do you have "ok google" hot word detection enabled? That was causing me some serious wakelocks, and I had forgotten I had enabled it to play with, it's usually not something I use or want. I'm still not sold on Google Home being a good thing because google knows everything there is to know about me. I'd rather some devices not know the pitch of my farts or where my girlfriend hides her phone when she has no pockets.
My battery life was still pretty decent though, amazing actually considering it was staying awake and always ready for my next command, but I know with it not running it will be much better.

You could have shown more infos from Battery Historian
If you wanna know what a proper Standby looks like, you can take a look at mine:
http://forum.xda-developers.com/htc...ark-thread-t3376159/post68929720#post68929720
but yeah.... there are a FEW known issues with HTC10 Standby....
A) 4g might cause more Batterydrain than 3G, but that was an early issue, and mainly on American Carriers.
B) WiFi does have shîtload of wakeups you cannot control. ExKernel has wlan_rx and wlan_ctrl divier options, set both to 8 (maximum) might help.
C) If you have Access to your router, maybe deactivating IPv6 can reduce WiFi Battery Drain.
To your 3 Questions.....

Power Nap [Xposed Module] also blocks them. But it doesn't matter. Because they do not wake the phone, they happen when the phone gets awaken by something else.
Check this out (With Power Nap enabled and What's app excluded)
As you can see, almost no Userspace Wakelocks:
As always Google Services is the only thing you simply cannot shut up, no matter what
But yeah, the Problem is on the Kernel Level....
You see a Normal Wake due to an UserSpace Wakelock:
And one that's happening due to Kernel:
So as long as you have these Kernel wakes, the BatteryServiceUpdateStats_3 will activate at the same time. Batterylife itself is not really affected.

2) Wish i knew what these Unknown Wakeups are.... Wish i knew!
3) i don't really like GSAM, i prefer BetterBatteryStats.
What does the Battery Historian say about CPU usage by App?

Hi, did you find any solution? same thing is happening in my lenovo k6 power but only when i use jio sim. if i don't use sim there is no battery drain in standby. check my attached screenshot of battery historian.

Hi try to reinstall other kernel, im using CleanSlate v2.2.0 now so far superb. and also install htc bost to sure not eat so much RAM usage.
Last time using elemental kernel but im lazy to configure, therefore battery drain quite fast even in standby mod.

Battery drains fast ( + screenshots)

Hi,
I noticed lately that my battery is draining fast. Like 1 percent for 50 minutes (In the best case) when the phone is on airplane mode and I don't touch it at all.
When I actually use the phone it goes down to like 2-3 minutes to 1 percent of battery.
I don't have root at all but used my PC to gain access for Wakelock Detector and as you can see in the pic I got 30 minutes of malwarebytes (I have the premium version with real time protection)
But usually Whatsapp is the one on the top with the most time on CPU
I have a few screenshots of Wakelock Detector in CPU, Wakeup triggers, and kernel wakelock. And almost a screenshot from AccuBattery app. I hope I can get to the solution with your help
Also I heard about AKT that you can get 7-14 screen time hours with it. Can I use it on my device? (of course after I root it)
Thanks in advance

you should uninstall malwarebytes if you want battery drain to stop. malwarebytes is malware by itself
And then, you may want to tweak whatsapp, it consumes too much power

How can I tweak whatsapp?
Btw I noticed that when I close whatsapp my battery is pretty normal so I think whatsapp is the main cause. I got pretty good battery even when malwarebytes was on and whatsapp always seems to take most of the battery bt AccuBattery app.

So 50 minutes for 1% with apps running isn't bad... And I see you're connected to network with two bars on 4G is that LTE or HSPA variant like TMobile does? 2 bars is going to drain your battery because your modem is going to keep trying to get better signal.. none of your screen shots show you in airplane mode as well

I said that I tried to put the phone in airplane mode and even closed all no-system apps with greenify but even then the battery went down 1 percent every 50 minutes.
Btw can resetting the device can work?
If I will choose reset it I will unlock the bootloader and root the phone too
And I still don't know if I can use AKM on my phone with snapdragon 845 after & after the phone is rooted)

Of course no, if you'll continue to use watsapp.

Lol I accidentaly commented from another device so it's a different account. Anyway, do you think the problem appears because it's Whatsapp Plus (which has a kind of malware in it which stoles data, but still I decided to keep it because of the features) or it's like that in normal whatsapp too?
If I will root my phone I will be able to find an alternative for the Whatsapp Plus features while using the normal whatsapp from the playstore so just wanted to know if whatsapp has this wakelock problem globaly (Don't know if this is the place, tell me where I can open a thread on it if this isn't the place ?)
