My OnePlus 5T is 3.5 years old and, after daily abuse, its battery life is starting to fade. But how bad is it?

OnePlus have a diagnostic tool which, annoyingly, isn't available in the Google Play store. And is a bit of a pain to run. So here's a quick tutorial.

APK Mirror have a copy of OnePlus Diagnostic 2.1. There may be a later version by the time you read this.

Download and install it. But how do you run it? I couldn't find it in my app list.

Install App Manager

From the F-Droid repository, install App Manager. This will show you all the apps on your phone and all the activities which can be launched.

Open the "Diagnose" app:

Under "Activities" click the "View Battery Status":

That will give you your battery state:

Mine is at 54%, so looks like I need a new battery!

Thanks for the guide, it was a indeed a bit of a faff to get it working. It seems that my OnePlus 7 Pro battery is still 86% healthy. I’ve had it for about 2.5 years so that’s not bad.

  Sounds like you already have it installed. You either need to find a way to launch it, or buy a new phone. Or, do as I did, and install Lineage OS.
