Why is my battery drained so fast? Look at the attached screenshot. The screen isn't even on.
You Wi-Fi shouldn't be using anywhere near that amount of power. I would reboot your phone, and if you've made any changes to your router, make sure the phone is actually connecting.
Hi norwegian82 ...
Welcome to Android Forums.
It seems that you may have a rogue or incompatible installed app. Perform a full "reset" of the device. Hopefully this should fix the problem.
Seriously? You'd recommend that before just doing a simple reboot? I've had this type of issue a few times (a lot more on my old Droid) and I've never had to do a full reset.
A simple reboot pretty much won't solve a problem like that.
Thanks for welcoming me to the forum
I'm trying a reboot first of all and then we'll see. Note that the wifi isn't even on when I had those last capacity drops.
Also look at the image attached.
Like I said, I've never had a reboot not solve a problem like that.
There is one other possibility. If the OP recently installed a new program (or updated an existing one), that could be the culprit. You can find recently updated programs in Play/My Apps.
So as you can see I lost 35% of my battery without really doing anything.
After trying a reboot.
I guess a reset should be the next step?
random question but does your phone have a habit of losing power completly at a random % and then the only thing that will get it going again is to plug in the charger?
otherwise, what exactly are you doing on the phone?
No, that has never happened.
I can loose a lot of capacity even if I'm not doing any thing.
Have you checked to see if it's connecting to wifi?
This was back when I owned a Droid 2G, but I used the automatic printer setup system (I don't remember what that's called) which set up a second network on my router AND changed my existing network in a manner that my phone no longer connected. It would repeatedly connect and disconnect every 5 seconds or so, which I imagine probably used a lot of power.
I had a similar problem with battery drain and turned out to be an app that stayed running causing a wakelock.
I installed an app called Wakelock Detector to figure out which apps are causing battery drain by either running constantly or running all the time.
You can find it here: https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en
When you have the battery usage showing and you select Wi-Fi, how much time does it show on CPU total? My phone has been unplugged for almost 9 hours and it only shows 9 seconds of CPU time.
OP, I notice the Clean Master icon in your notification bar. If you are using the task killer (or "1 Tap Boost") feature of that app, it could very well be the cause of your issue. Task killers are totally unnecessary in recent versions of Android, and cause drain by constantly killing off system processes that automatically restart themselves.
So before I fell asleep last night I turned off wifi and closed open applications. The battery level was then at 41%. I then locked the phone turning screen off. After 2.5 hours I'm awake and checking my phone and it's dead. Battery empty...
I'm uninstalling the "cleaner" now to see if it may be causing the trouble.
If I do a total reset - should I just restore everything afterwards or will that just cause the problem to persist? If I install all my apps.
Along with WakeLockDetector, get either Battery Mix or GSAM battery monitor and see if you can find any particular app that's draining your battery.
Killers may have been unnecessary in any version of Android, but they are clearly unnecessary in a phone with 2GB of ram.
I think we may have discovered the cause.
using GSAM.. main culprits are SCREEN.. my SMS app(lowest of these 3 listed), and the OS..
After uninstalling cleaner app:
65% left after 10.5 hours.
I think it's fair to say my problem is solved
Thanks a lot for your help!
