Am lost I just don't understand what it does and how it works so if someone can explain it to me so I will keep it a couple more days and check back to see if anyone posted any help thx
Amazing Tool This application is awesome in its ability to help evaluate all the battery life extension hacks for functionality and efficiency. I can monitor whether a battery saving apps is working and to what extend. Using CPU Spy Plus allowed me to configure my Samsung Note to deep sleep 95% of the time allowing my phone to last about 36hrs with moderate use. Thank you for making such a functional app available for free. As off 7/17/15 CPU Spy Plus have allowed me to tweak my phone to deep sleep 97% of the time
Once I wrapped my head around it... Once I wrapped my head around it, this app was tremendously helpful in diagnosing battery drain while "idle." I wish it could drill down to the individual apps, but even if it could before, Kit Kat has killed that ability (thanks, Google). Great info, small app, does what it says on the box. Im happy.
Very useful This app helped me diagnose a wake lock problem I had on my note 3. If this app had been able to pinpoint the cause of my problem rather than just tell me my phone has a wake lock problem I would give it 5 stars easily.
good for advanced users with battery drain problems This showed that my phone wasn't going into "Deep Sleep" at all, but at least it was spending most of its time running at minimal frequency (384 MHz). I'm reducing from 5 stars to 4 because it remains as an active app even after you seemingly exit it via the back button (only way I've found to make it exit is forcibly via the task manager). If you just want to know the Deep Sleep percentage (not the cpu frequencies), Deep Sleep Info by Carsten Mueller is simpler and provides a nice widget that shows this %.
Great app This app is definitely recommended if you need to see if your cpu is running at high speeds more often than your kernel should have it
* (add) Non-compatible devices: deep sleep info NOW available
* (add) idle states: more infos (and improved the activity core)
* (add) idle states: added buttons to refresh, reset and set timers
* (fix) refresh button won't delete the timer if "cable option" is disabled
* (fix) other 4 bugs you reported ( thanks :D )
