The website price being the price you actually pay is something we take seriously, so it's good to know that came through clearly, Achyut. Two hours for a leaking display and a battery replacement in Antwerp is exactly the kind of turnaround we aim to keep. Enjoy your phone now that it's back in shape!

Common OnePlus 9 problems
Drains quickly
Do you need to charge several times a day? A worn battery holds much less charge than when the device was new.
Shuts down unexpectedly
Does the device switch off while there’s still charge left, especially in the cold? That’s a typical sign of a battery at the end of its life.
Gets warm or swells
A battery that heats up or makes the device swell is best replaced quickly — to prevent damage to other parts.
Charges slowly or erratically
Does the charge percentage jump around or does the device charge slowly? The battery (or the charging port) could be the cause. We run a diagnosis first.
How it works
Diagnosis
We measure the battery condition and confirm whether a replacement is the solution.
Replacement
We fit a new battery and reuse the original seal where needed for sturdiness.
Testing
We check charging and stability so your device works reliably again.
