Replacement Battery for UMIDIGI A7 Pro

This lithium-polymer cell is built as a direct replacement for the UMIDIGI A7 Pro smartphone. It matches the original 1ICP/5/65/87 part number and supplies 3.85V with a 4000mAh rating. The pack is intended for owners whose factory battery no longer holds a useful charge.

Fixed Capacity and Voltage Limits

The cell delivers a fixed 15.4 Wh at 3.85V and cannot be fast-charged beyond the phone's built-in controller. Capacity will fade with normal cycle ageing and the polymer chemistry does not support user-accessible calibration routines. Runtime depends entirely on the handset's power management firmware.

Simple Swap With Adhesive Caution

The 76.30 x 64.40 x 4.40 mm pack fits the A7 Pro's internal cavity without modification. Installation requires only a compatible screwdriver set and careful separation of the glued back cover. The main risk is puncturing the soft pouch while prying the old cell loose.

Questions about this item

Which battery capacity should I choose for my UMIDIGI A7 Pro?

The DS-CS-UMA710SL provides 4000 mAh at 3.85 V, delivering 15.4 Wh — the exact specification for the A7 Pro.

What does the 4000 mAh rating mean in daily use?

It represents the charge the cell can store; combined with 3.85 V it yields 15.4 Wh, which determines how long the phone runs before recharging.

What connector standard does this battery use and what does it limit?

The pack uses the OEM 1ICP/5/65/87 flex connector, so it fits only the UMIDIGI A7 Pro and caps compatibility to that model.
