How to check battery health on your OnePlus smartphone


When it comes to battery on our smartphones, there are a myriad of things that could affect the longevity of our devices. Cranking the brightness and volume to max levels could affect battery life, playing games all day, watching videos back-to-back, bad software updates, and so on all play a role.

There are also other factors that are hardware-related, such as having a battery that can no longer hold its maximum charge.

This is due to the fact that lithium-ion batteries usually have a fixed amount of charges it can handle before it starts to degrade. With every full charge (0-100%), your battery losing a charging cycle, after which it will get to the point where your 4,000mAh battery is no longer operating as a 4,000mAh battery.

This is normal for all lithium-ion batteries in smartphones today, so if you want to know if maybe it could be time to replace the battery in your OnePlus smartphone, here’s how you can do it.

  1. Download the OnePlus Diagnostic app
  2. Launch the app
  3. Under “Battery Capacity”, tap on “View Battery Status”
  4. Under “Battery state”, it will show you the max charge on your OnePlus battery and if it is still healthy or if it is at a “Serious Loss”

If the state says it is at “Serious Loss”, this doesn’t mean your phone will no longer work. It’s just an indication that your battery no longer holds the charge like it did when it was new. This means that you might find yourself needing to charge your device more often than before.

At this point, you have several options to consider. You could always consider bringing a power bank with you to keep your phone topped up, or you could also consider having the battery replaced. How much this will cost will depend on where you send your phone in and which model you have.

Lastly, you could also consider buying a new handset, although this would be a bit extreme depending on how long you’ve had your phone, and it could be cheaper to just pay to get the battery replaced if you plan on keeping it around for several years.

Generally speaking, most devices tend to still hold around 80% or so of their charge over the course of 2 years, any longer and you might dip to the 70% level. Your mileage may vary depending on your charging habits. For example, keeping your phone plugged in for extended periods of time will impact battery life.

Some have recommended that you only charge your phone to 80% and never let it dip below 40%, but we imagine that this can be a bit troublesome to have to monitor.
