Also, you can check if battery is bloated.
My problem is about weird battery performance. On active usage and deep sleep mode is spending nearly same amount of battery. When i look battery statistics, slope of the battery usage is not changing whether i use phone actively or not. I am giving same example again; first day i spent all of my battery with 4 hours active screen usage and 1 hour phone talk at 10 hours, second day my batttery was over with 1 hour active screen usage and and no phone talk at 12 hours. At battery statistics, screen usage and phone talk was first and second at that two day. Second day nearly all of my battery was spent by deep sleep mode. At that two days, i fully (%100) charged my device with same (original) battery charger.
I should say that i am not a novice
My bluetooth, wifi, and gps was always off only mobile data on, and only 2G
And at performance section it am using smartass2 (freq min 0.2 - max 1) and sio. At developer section max 4 process at background. I am using ipromeh's [4.2.2]Touchwi5 ROM build 8 with madridii's last 3.0 kernel. I made battey calibration and tried hursky's 3.0 kernel too.
I had a wonder 1 year ago but i sold it. I faced up with the bloated battery problem last year with my old device. I know it. Now, my battery is not bloated. New phone that i have bought from a friend was nearly not used. Therefore i can say that i am using a firsthand device without service guarantee. I have heards some battery problems that are resulting from hardware (something releated by battery on mainboard). Is the problem can be caused by hardware? If the problem is about hardware that will be quite big issue for me.
What can i do for solving the problem?
