Doesn't work with 4.4 This app mysteriously stopped showing any information on my GS3 about 7 months ago. I reinstalled it on my GS5 and I'm faced with the same problem. The only similarities are Android 4.4 and Samsung phones.
Crap App! According to this app: 1. My display has consumed 4,286,604.92 ma with 29.52% usage. 2. A background process which is part of the system has consumed 1,293,911.23 ma or approx 10% usage. Did you know that 4,286,604.92 ma + 1,293,911.23 ma = 5580516.15 ma = 5,580 A = 5.58 KA ? Using the GS3 battery voltage of 3.8 VDC, we get a power output of 21,204 W or 21.2 KW. IN other words, this app has just told me that 39% battery usage is the same amount of power as my house uses in 6-8 months?! If only my phone had this much power! Like I said, CRAP APP! Case rested!
Math is WAY off! Aparently in an hour and a half my gs3 display has used 617.4amps but only used 18% of my 2100mah battery..... Hmmm, 21amp battery - 617.4amps = - 596.4 amps. Don't download.
Good for finding power killers If you don't pay attention to the really bad milliamp readings, its a good app to find problems. Found a problem with an app looping and thus cured my battery crisis. Still don't see how my screen can pull 9 Amps though. Needs a bug fix or two
Doesn't show usage This app doesn't show any usage on my GS3. It just shows fully charged and nothing else so I'm going to uninstall.
Does not work on 4.4. Please update!
