    i recently bought a chinese gaming tablet and it works great but the battery only lasts for 2 hours

    my device has these specs
    RK3028 chipset (cpu: 1GHz dual core + mali mp2 400 GPU)
    512 RAM DDR3
    2500 mAh lithium battery
    5 inches led screen
    frontal and back cameras
    android 4.2.2 JB


    the battery tab at the setting says that the battery is used 100% by the screen, the gsam battery monitor's appsucker only lists the apps that i use google services are there but it doesnt uses any battery, when i check the running apps it only shows the system UI and the keyboard, yet its using 400 MB RAM

    looking on the installed apps i found 3 suspicious ones there are "armfreqtest" "stresstest" and a chinese named app
    these 3 have permissons for everything, even the phone and GPS functions that it doesnt has since its a tablet, could these have something to do? is it safe to remove them with titanium backup?

    Welcome to Android Central! That's probably to be expected from that device, especially if you're using it to play games a lot. Screen is one of the main battery consumers, as well as games. A 2500 mAh battery for a 5" device isn't particularly big. As a comparison, the Nexus 5 has a 2300 mAh battery, and I can get about 3 hours of total screen-on time at best.

    i dont think thats the problem here, even with wifi off with no running apps, just the launcher, the battery wont last more than 2:30 hours
    playing games doesnt affects the battery duration for some reason

    It could be a number of issues--you kind of take your chances with no-name devices direct from China. Maybe the battery isn't actually as big as it claims. Maybe there's a hardware or firmware flaw. It may end up being very difficult to determine, short of taking the thing apart, and maybe trying to replace the battery (if you can even find a proper replacement).

    Battery saving apps are usually not the way to go. Most often, they are placebos as opposed to actually helping overall battery life.

    As for the OP, I am wondering if cell signal is culprit.
