According to a Reddit thread, OnePlus India is currently offering free battery replacement for the OnePlus 3, OnePlus 5, OnePlus 5T, OnePlus 6, and OnePlus 6T. All you have to pay is the labor cost for the exchange. That’s only 473 Indian Rupees (about $ 6 or € 5) for a single user OnePlus 5T.
This applies if you step into the OnePlus official store and does not apply to courier pickups that may incur additional charges. I think the reason for the move is that the company has a large amount of unused spare batteries for the mobile phones mentioned above, and because it is now quite old, we do not expect demand for these batteries to be very high. I will. Therefore, choose to make them available (almost) free of charge. This can lead to goodwill from OnePlus customers.
Given the age of the device in question, this is a great time to bet that most of the devices still out there will definitely use a new battery for now.
You can also check the battery health of their device through the OnePlus Diagnostic app. In the app, you need to check for “View Battery Status” on the main screen. Tap on the option and you will see the battery health of your device at the bottom. If the battery health is less than 70 per cent, it is advisable to get it replaced. Doing so will not only offer more longevity but also could result in more screen-on time.
Note that if you don’t want to risk it and you just go into the store to replace the battery, you can do so Book service online Instead, but in that case, you only get a 50% discount.
