Replacement battery for OnePlus 7 Pro

The Cameron & Co DS-CS-OPA720SL is a 3.9 Ah Li-Polymer cell built for the OnePlus 7 Pro series, including the GM1910, GM1913 and GM1915 variants. It restores full runtime to phones that hold a charge for only a few hours. The black finish matches the original look. It is sold new and ready to fit.

Swaps out the factory BLP699 cell

This unit replaces the original BLP699 battery rated at 3.85 V and 15.02 Wh. The upgrade is worth it when the phone shuts down early, throttles under load or the back cover bulges. It brings the capacity back to 3900 mAh without changing the voltage profile. No extra capacity beyond the stock figure is offered.

Fits inside the sealed 7 Pro chassis

Installation requires opening the glued rear glass, disconnecting the flex cable and lifting the old pouch cell. The replacement measures 64.10 x 61.30 x 5.83 mm to match the OEM footprint. Common issues are torn display cables, cracked glass or lost water resistance if adhesive is not reapplied correctly. Professional fitting is advised.

Questions about this item

Does the 64.10 × 61.30 × 5.83 mm size match the original BLP699 battery bay in my OnePlus 7 Pro GM1910?

Yes — the pack is built to the exact 64.10 mm by 61.30 mm by 5.83 mm footprint of the factory BLP699 cell, so it seats in the 7 Pro chassis without modification.

What is the common mistake when fitting this 3.9 Ah Li-Polymer pack into a OnePlus 7 Pro GM1915?

Forgetting to peel the thin adhesive liner off the replacement frame before pressing the battery down; the liner blocks the glue and the cell can lift later.

When should I plan to replace this 3900 mAh Cameron Sino battery in my 7 Pro Premium Edition Dual SIM GM1913?

Replace it once a full charge no longer lasts through your normal day or the phone shuts down above 20 % — typically after a couple of years of daily charging.
