Re: My battery life sucks what's wrong ?
Can someone with SystemPannel run a test for me. I want to get a 2nd set of data points to check something with.
I use SystemPannel to check my CPU usage. I normally set it for a 2 hour window, and during stand by my CPU is in the 3-5% range.
However i have run across something interesting.
The other night i left my device connected to WiFi and found it was in the 30% range the entire time.
I normally dont use WiFi as my TMO coverage is strong, LTE is strong and very fast.
With other devices i have noticed slight increase in CPU usage when in stand by and on WiFi, which is normal as its running another radio / connection so yeah more things to process. My note 3 for example uses 4-6% more. This is all per the app, SystemPannel. So trying to keep things the same.
IF someone has the app, and has TMO (using ATT should get similar results but Sprint/VER might get different since they are CDMA) please set it for 2 or 8 hours and let it sit on the charger over night and report what your device is like in the morning.
I will continue to run a few more tests with NFC off and also toy with a few other options.
EDIT added pics.
The first pic shows 8 hour window. I also rebooted the phone in the middle of the 8 hour window to make sure it wasnt a rogue app. You will see WiFi on then off then back on. Second pic shows 2 hour window and it started with WiFi off then on. Notice the CPU jump.
