This CPU monitor is a great way to keep an eye on your battery drain. No matter what app you're using, the Micro CPU Monitor can tell you at a glance which applications are chewing up your CPU cycles.

---Frequently Asked Questions (FAQ)---
Q. I've got a quad core device. Why don't I see all four cores being used?

A. Android tries to optimise the CPU usage, by shutting down cores when they're not needed. Your phone will rarely use all 4 cores. Try downloading a CPU Stress Test app, and you'll see the four cores then :)

+ SYSTEM_ALERT_WINDOW - Required to create a system-wide overlay for the monitor on edge of screen
+ RECEIVE_BOOT_COMPLETED - Required for the auto-start feature
+ INTERNET & ACCESS_NETWORK_STATE - Used for error reporting, and anonymous usage reporting using Google Analytics.

It works GREAT on my Samsung Galaxy tablet, extremely happy with it! Very reliable, too. However, on my new LG Rebel 4 LTE phone there is no bar with CPU activity, only the empty black line 1 pixel high. Can you help? :-)

Used this app for years with no problem but recently I updated my phone to Oreo (Android 8.1, using a Moto G5 Plus) and it stopped working. Now looking for a replacement
