CPU Master: Monitor CPU and Battery in Real Time Anytime!
CPU Master - Battery Monitor is a robust and free application for Android devices. It tracks all current CPU usage, frequency, and statistics in real-time, while also keeping an eye on CPU temperature, battery information, and the approximate temperature of the device or CPU. The application is user-friendly and lightweight.
FEATURES
- CPU Monitoring:
CPU Master provides real-time monitoring of CPU temperature and frequency, analyzing historical data to show which processors are currently active and which are inactive, with support for multicore CPU tracking.
- Battery Monitoring:
The app displays comprehensive details about the device's battery, including power status, voltage, temperature, health status, and charging progress, such as the estimated time needed for a full charge, along with other useful information.
- App Management and Uninstallation:
This application offers a free and straightforward uninstaller for Android devices. It allows users to manage apps effectively and reclaim memory space on their phones or tablets. You can remove multiple applications simultaneously and view additional details about them. Regularly uninstalling unused apps can help free up storage and reduce resource consumption (battery and RAM). Sorting options by name, size, and installation date (both ascending and descending) are available. Note: This app does not support the uninstallation of system apps.
Comments
When I installed this app I had the impression that it would cool my phone since CPU has gotten hot. I had used this sometime before and it worked wonderful. Now there's no separate way for me to be able to cool my phone. What happened to the previous version that I had used? So far I'm disappointed with this app. I will rate this at a later time and see if this improves.
CPU Master & ' Battey Monitor' is just Ads with a few Monitors squeezed in between - I Uninstalled it Seconds after Starting it up !!! Don't waste your time Downloading it. ( Unless you're curious to see just HOW BAD it is ) Not sure if it was made as a Bet or a Joke - certainly NOT as a Serious Tool / Util. It looks like it was made on one of those "Make your first App in 5 Minutes" for Beginners - type apps. There's almost NO GUI to speak of. It's Not Good ! Sorry to be so harsh. - Mike -
I have had CPU Master Cooling for about 21 yrs, it almost worked well cooling down my cell phone. But a couple months ago or so, you all "updated" the way it "works", & it doesn't cool NOTHING. So this is why I'm taking my business away from your product bc it DOES NOT WORK AT COOLING DOWN MY PHONE. So on a scale of 1 to 10, I would rate it -50. Guys, when you have something that works... don't fix it. If you change and go back to the ORIGINAL way it used to be, I'll be a customer again.
I love this app at first my phone was heating so badly ending up to freeze I had to wait for 15 minutes so that it gets back normal but since I decided to Search for cooler app I ended up downloading the wrong app which I downloaded Las time and it was kicking me out not until I bumpted into this app now my phone is functioning properly and it heating at a normal temperature I give it five đ star for it
Just installed this app, so I cannot comment much, but, it seems to be a good app. I was charging my phone while the app was operating and reflecting the charging process result. Looks fine and good. Best of all, this app does not require high bytes to install. Thumbs upđ
Doesn't let you choose to cool your phone down the CPUs on your own. I downloaded it and the only thing I could do was my battery and it showed the temperature scale which was high but I couldn't cool it down.
