Battery drain issue after 4.4.3

[B. Diddy]

Huawei Ascend Y300.

100% charge when I left home this morning. 6 hours later, lost in Wales pulled the phone out and it is on 9%?
Two calls and the battery was totally dead, so couldn't even use the SatNav.

Welcome to Android Central! Just so you know, this thread is in the Nexus 5 forum.

There are lots of potential causes for battery drain. It is usually helpful to see screenshots of the Battery stats screen, the fullscreen battery graph, the Screen category, and the Cell Standby category. For battery saving tips, see this guide: http://forums.androidcentral.com/am...how-tos/298919-guide-battery-saving-tips.html

I don't know if people are still interested in this but I found a temporary solution, until an update that fixes all this comes along. I have a Sprint Note 3, not rooted.
Like everybody else, I had great battery life, until one day Android System started being the no.1 battery hog, followed by display etc.

I found an app called AppOpps , and what that allows you to do is turn off individual permissions that every app on your phone has. And it shows you in real time, what app is using what resource.
For example I found out that GoFlashlight was using the camera in the background (uninstalled out of principle). Skype was using the camera in the background even though I was signed out of it. Etc etc.
When it came to apps that were using my location, one of them was a package called .... Android System v 4.4.2 ....


So what I did was to turn off its permission to use Location, and if you go all the way down, you can turn off the Keep Awake permission.

That's it! Enjoy your great battery life once again!

There are two possible apps. Is it just the App ops or App Ops Starter?

update: Doesn't matter which. On Nexus 5 KitKat 4.4.4 neither works. App Ops won't launch. App Ops Starter fails with an error that Settings has stopped.

Yep. None of those permissions limiting interfaces work anymore.

Why would we want to allow users to control which permissions apps can have on a device they own? Then we could actually restrict a bad app from doing something it shouldn't do in the first place. Having only the choice to install or not install something is hardly much choice. But apparently, having such control would give us too much power and could hurt the ability of developers to spy on us and annoy us. Or people that don't know what they are doing would "break" apps and then clog up support channels.... Um, but we can "disable" apps now, which also can break the phone from running correctly when used improperly... but that won't hurt spying or adware procedures, so that must be OK.

Oh right- we are supposed to just root and void the warranty, no longer be able to access certain streaming video with DRM, make updates much more difficult, and possibly screw up the phone.

This is what happened to me on HTC M8.. yesterday, at mid day, phone's battery was 82% and suddenly while playing boom bash , battery sign gone red saying no battery and phone switched off. Took a charger and phone started from 0%. Later today, battery was 62% and while doing whatsapp, same things happened. Started looking over the net, some saying.Sudden death syndrome, some.suggesting.hard reset etc. Chatted with HTC support and they advised me to do cache clean partition via startup menu. I did it but once I reboot it, battery was down to 3% as mentioned in the first post.

Please advise and help. Phone is just a week old.

Just found this thread and wanted to add that "App Opps Starter" does now work non root. At least it does on my TF701 on 4.4.2.

Trying out the fix in post 142

Strange, that app clearly says it will not work and it hasn't been updated in almost a year now. I just installed it and it does nothing but redirect you to the regular/standard settings menu.

And App Ops (non-Starter) seems to indicate it needs root, then clearly states it requires root when you install and run it. (Tested on N5 running 5.0)

I don't know how on a nexus but the issue seems related to how the device reads the battery my Samsung note 8.0 dichroic fast and charged fast. Tried all the things I could. Then I disconnected the battery for a couple of hours. Some say 15 minutes is enough but I went out. I can go 24 hours with light use or all day with heavy use. An hour of HD streaming takes 10%.

My Nexus 4 battery life was very poor after uppgrading to 4.4.4. The phone was also getting hot for no apparent reason. Last week the email app went hatwire and kept reporting "Unfortunately email has stopped". I deleted all email accounts from this app and removed the App. The Gmail App works just as well (somehow it knew about all my email accounts) and my battery life has significantly improved and the phone runs cooler. I hope this helps.
