I have a Galaxy II 4G purchased this last December and within the last week it loses power very quickly even when turned off. I can plug it in to charge it and after it reaches 100% I unplug. I leave it turned off (not shutdown completely, but I press the button on the side to turn off the screen) and in just a couple of hours the battery charge reads something like 95%. By morning it is around 87%. And all this time I did not use my phone, I received no emails, messages, phone calls, etc. I've tried to shut down nearly every running application that seems unecessary and still I have the same battery drain.
How can I determine what is draining my battery? Is there an app that will track things like this? I use task manager to turn off an app everytime after using one.
Any information would be appreciated. Thanks!
Correction: My phone is a Galaxy S 4G.
Thats normal the built in apps does nothing you do about it.
I'm not sure I understand gtbicu. What's normal? That the phone's battery drains without being used?
I should mention that this is a new situation with this phone. Prior to a couple of weeks ago, I could charge it up fully at night and in the morning it would be at about 97% or 98%. Like I said above, now the battery is around 85% to 87% by morning.
I mean the apps you installed and t mobile apps does it nothing u can do about not unless u power off it.
Thanks gtbicu, but I haven't installed any new apps and this is a recent phenomenon. Just a couple of weeks ago, my phone would hold a charge for hours. Now it loses 10% in standby mode in just a couple of hours. I just got the phone in December so I wouldn't think the battery is the issue. Are there some apps that just turn on by themselves and run in the background?
If you did not install new apps recently, it is possible that you updated an app or some app setup to update automatically. Also Bluetooth, WIFI, 4G data and GPS use a lot of power. Do you use wifi, is it on, is it on when connection not available, did you move your phonne further away from the signal source? Location of cell tower could change or phone location relative to cell tower could change and affect power consumption. Switch your phone to airplane mode and see how it affects batterry life.
You mentioned that the phone is a few month old, but batteries loose their capacity over time. Not sure about cell phone battery, but laptop battery looses 10 - 20 percent of its capacity every year.
