Why Your Mi 12 | Mi 12X Battery Wears Out
Every phone battery has a life of around 300 to 500 charge cycles. After that, it starts holding less and less charge. So if your Mi 12 | Mi 12X used to last a full day and now it barely makes it to the afternoon — the battery is the reason, not the phone. Replacing it is the simplest and cheapest fix.
About the BP46 Battery
The BP46 is a 3.85V Li-Polymer battery with 4500mAh capacity and 17.33Wh energy rating — built around the listed device specification battery that came inside your Mi 12 | Mi 12X. It fits into the same slot without any cutting or modification. The built-in protection chip stops charging automatically when the battery is full, so you never have to worry about overcharging.
How to Get It Installed
If you have never opened a phone before, we suggest going to a local mobile repair shop. They will do it quickly for around a small service fee. If you are comfortable doing it yourself, watch a teardown video for your exact Mi 12 | Mi 12X model on YouTube before you start. The pry tool and spudger included in the box are the only tools you need.
Warranty
Every BP46 battery comes with a 6-month replacement warranty. If it stops working normally because of a manufacturing issue — like losing charge too fast without any damage — we replace it. Contact Welzone support with your order ID and a short video. We process claims within 3 working days.
Delivery
Dispatch timing depends on order time, stock and courier pickup. Delivery time depends on your pincode and courier route. You will get updates on SMS, email, and WhatsApp. Cash on Delivery may be available on eligible pin codes.
