I've had my OnePlus 9 for about three years, and lately, it's been charging ridiculously slow and the battery runs out much quicker than it used to. I misplaced my original Warp Charger, so now I'm using my brother's OnePlus Nord 5 charger. I'm wondering if this Nord charger could be the reason for the slow charging or if the battery deterioration is just due to the phone's age. Should I invest in the original Warp Charge 65W charger again, or would it be better to replace the battery at this stage? I'm seeking advice from anyone who's faced a similar issue.

Using a lower power charger like the Nord might be part of the problem, especially if it’s charging slowly. The rapid battery drain, on the other hand, is likely due to the age of your phone's battery, so you might need a replacement. Keep in mind that a 65W charger can actually reduce your battery's lifespan if you're often doing quick charges. I personally use a 5W charger for overnight charging and it helps keep the battery healthier in the long run.

Thanks for the tip! If I decide to replace my battery, where can I find an original OnePlus battery?
