Get Your OnePlus 5 Working Like New
Buying a new phone just because the battery is weak does not make sense when a battery replacement costs a fraction of the price. The BLP637 is made to the exact 3300mAh specification of your OnePlus 5. Once installed, your phone performs exactly the way it did when you first bought it.
Matched to Your Phone’s Original Spec
The BLP637 runs at 3.85V and stores 12.71Wh of energy — the listed battery numbers for your OnePlus 5. This means charging times, battery life, and heat levels all stay exactly the built to match the listed device spec. The Li-Polymer cell also has no memory effect, so you can charge it from any level without reducing its capacity over time.
Professional or DIY — Your Choice
Taking your OnePlus 5 to a local repair shop is the easiest option. Most shops charge a local service fee for battery replacement and finish quickly. If you want to do it yourself, the included plastic tools are the right ones for the job. Look up a video for OnePlus 5 battery replacement on YouTube for the exact steps.
Simple Warranty Process
We give a 6-month replacement warranty on every BLP637 battery. If anything goes wrong because of a manufacturing defect — not physical damage — we send a replacement. Reach us on WhatsApp, email, or the Welzone website with your order number and we will sort it quickly.
Shipping & COD
