Cryptomining apps are often the cause of poor battery life and sluggish performance. They can also prematurely kill your phone or PC/Mac.

When we test phones, PCs and Macs we reset all to factory defaults. We remove all Bloatware. That way we get fair battery and performance results. These are inevitably way longer or better than you get in real life.

But it is only after using a device for a while and downloading apps that you begin to understand what is causing issues.

Recently cryptomining mining apps have become the craze. Make a few bucks while you are not using your phone or PC. Or they may simply be part of malware.

Apple has banned cryptomining apps from its Apple Store

Its recently updated app store review guidelines now explicitly state, “Design your app to use power efficiently. Apps should not rapidly drain the battery, generate excessive heat, or put unnecessary strain on device resources. Apps, including any third-party advertisements displayed within them, may not run unrelated background processes, such as cryptocurrency mining. If your app uses location background mode, include a reminder that doing so may dramatically decrease battery life.”

Apple takes this a step further with rules for Cryptocurrency apps. “Apps may not mine for cryptocurrencies. Cryptocurrency apps may not offer currency for completing tasks, such as downloading other apps, encouraging other users to download, posting to social networks, etc.”

Thanks, Apple.

Apple iOS and Google Android 8.x also have app monitors that will put background apps to sleep and identify power hungry ones.

Google has not banned cryptocurrency mining apps

It is now refusing to accept advertising from “Cryptocurrencies and related content including but not limited to Initial Coin Offerings, cryptocurrency exchanges, cryptocurrency wallets, and cryptocurrency trading advice.”

But its Play Store is littered with Cryptomining apps (See here).

And malware is now being used to spread cryptomining – see GadgetGuy’s article here.

Unfortunately Microsoft also allows cryptomining apps (See here) in its Store.

What is Cryptomining?

Where banks have massive mainframe computers to keep track of customer transactions cryptocurrencies rely on the public to keep their blockchain-based ledgers a.k.a. cryptomining.

Cryptomining is the process by which transactions are verified by a vast pool of public computers and added to the public ledger, known as the blockchain.
