Best apps for monitoring system performance on your Android device

If you're the kind of Android lover that needs to know absolutely everything about the performance of your Android device then you probably want to monitor your device's performance in real-time. Luckily we've listed the best apps that let you do just this, so you can identify problematic WiFi connections, power hungry apps, irregular CPU behavior or background processes that are sucking up your data allowance and chewing your battery. Here's how to monitor the system performance of your Android phone or tablet.

Network Monitor Mini: the great mini widget for your home screen

Network Monitor Mini is a mini network monitor. Go figure. The app allows you to keep a tiny readout of your current network upload and download speeds floating on top of whatever else you're doing. This lets you keep an eye on which websites are chewing your data, and how, in real time. The information can be placed anywhere you like on your screen and you can also set the font, color, ''tap through'' option (instead of opening the app), transparency and more.

System Monitor: real-time system information

An oldie but a goodie, System Monitor hasn't been updated for a while and it shows in the interface, but the guts are all good, as they say. You can set up resizable widgets to display how your system resources are being used in real time, including current CPU load and a battery and memory monitor (both RAM and SD). There's the usual array of task manager features too. If you want to feel like you're sitting at the engineering panel of Android HQ, this is one of the best apps you need for monitoring system performance on Android.

TinyCore: minimalistic widget with the necessary info

If a screen full of system monitoring widgets is a bit too obtrusive for your minimally crafted homescreen aesthetic then TinyCore has you covered. This thing is minimal. And I mean minimal. So minimal that you wouldn't even know it was there unless you were looking for it. TinyCore is a system monitor app that adds a tiny line above the clock in your system bar to visually display at a glance your current RAM or CPU usage. If you want to fork out for the Pro version you can also add CPU frequencies to the display.

Disk usage: information kept simple

If numbers, graphs or simple lines are too complicated for you, then how about a big old chart that shows how much memory a certain file or directory is taking up based on how big it is on the screen? Sounds perfect. Well that is exactly what Disk Usage does: lets you monitor what takes up the most space in local or external memory by showing you proportionately sized blocks on screen. There's no interpretation of data required here. It's great if you want to identify large files and clear up space.

CPU Temperature: how hot is your smartphone?

Considering the frequency of battery draining, CPU chewing and overheating firmware updates floating around, some hard data might be useful to have on hand. Knowing what a normal range for your device is also lets you know exactly when things are abnormal. Not that your palm isn't a perfectly good thermometer, but CPU Temperature will let you monitor your CPU temperature and clock speed, battery temperature and charge level and give you a bunch of cool graphs so you can view changes over time. You can also get an overlay for your status bar so you're always in the know on what's hot and what's not. Yes, I just said that.

The Android system actually has a few built-in options for keeping tabs on running processes too. Process Stats are accessible via the Developer Options menu in Settings. If you don't already have this menu enabled, just go to Settings > About Phone and tap the Build Number repeatedly until the notification pops up. Developer Options will now appear at the bottom of the Settings menu. Process Stats will tell you what percentage of the time an app is running as well as its average and maximum RAM usage. You'll also get a list of currently running processes attached to that app and the ability to force-stop them.

Likewise, check your battery section. Tapping the listed apps and services will show you a breakdown of the biggest battery suckers, what processes they're running, how much battery they're eating, wake lock stats, mobile and WiFi data sent and received and more. Also, check your Apps section and scroll to the Running tab, this is where you can learn which apps are always running on your system for good reason (like WhatsApp or Google Play Services) and those that shouldn't be (games you're not playing or music players you're not using).

What would be your best apps for monitoring system performance on Android?

  • "Simple System Monitor" does the trick for me. Clean Material UI and all the graphs and stats you need.

  • I like that. My phone has inbuilt monitor for network speed though

    Hi, I am interested in an application, in the line of System Monitor, that allows you to monitor the system (CPU, mem, battery, network...), and also generate monitoring session reports (pdf, xml). Display widgets with graphs in real time are not necessary but is cool.

  • I use COOL TOOL from Deviantstudio. It's pretty much like the small task manager symbol in the windows 7 system tray area showing how the load is of your computer. It has an overlay and I put it at the top between the clock and the notification icons. This gives you at any time an overview of the load on the phone.

  • I need an app which will measure internet data usage per hour. I use Data Usage app from triladroid ( and completely satisfied with it. But maybe someone would recommend another data usage app with statistics per hour?

    • I can recommend 3G WATCHDOG. I use it since years and works great, Lots of customizations and statistics. I bought the PRO version long time ago

  • This is a good list of apps. There's another you might want to consider.
    - Trepn Profiler shows accurate realtime power consumption on Nexus and some HTC devices.
    - It has an configurable realtime overlay mode that show the frequency, load of all of your cores. It also shows GPU frequency and load.
    - It is the only app I'm aware that shows the state of the cellular radio (transmitting, idle, dormant, etc).
    - It captures both Wi-Fi and cellular data usages and can show which apps are wasting your data.
    You can download it at: It's free, but you need to put in an email and register.

    I use X-plore file Manager it has Disk Usage incorporated into it. It's a "must have" App..

  • some best apps are reviewed here

  • I use Auto Memory Manager on my G3. The plus: it gives automatically more RAM when necessary.

  • Android apps have a big impact on monitoring your system performances. It helps us check how we have used our gadget.

    I use android tuner, a xposed module( I hope most have heard of it). I know you have to be rooted, but it's the best tool that I have used. It's way more complicated than any of these apps, and you have to know what you're doing, but it can do all of these things, in one app. If you use it , install in internal memory( most xposed modules run much better in there). Titanium backup Pro, is a beast too. This tool(and many more xposed modules), saved me from looking for a way to unlock my bootloader,and install a custom rom. I get as many features, as a custom rom( all the important features, that drive many to custom roms, in the first place).
