This compatible battery replaces the failing battery of a Samsung Galaxy A80 and restores the device's autonomy at a controlled cost. An economical alternative to the original part, it undergoes systematic quality control before shipment to guarantee its stability and compatibility with the A805F model. You maintain the phone's performance without bearing the cost of the manufacturer component.

When to replace your Galaxy A80 battery

Autonomy reduced by half compared to the first weeks of use indicates advanced wear. The Galaxy A80 shuts down before displaying 0%, refuses to start without the charger plugged in, or takes several hours to reach 100%. The battery sometimes swells and deforms the rear cover: this last symptom requires immediate replacement to avoid any risk of damage to the screen or motherboard.

These signs appear after 500 to 800 charge cycles, approximately two years of daily use. Daily charging accelerates the chemical aging of lithium-ion cells, and capacity gradually decreases until it no longer lasts a full day.

What the package contains

You receive the battery only, without fixing adhesive or disassembly tools. The cell is ready to be connected to the Galaxy A80's power flex cable as soon as the rear cover is opened. Provide a plastic spudger to detach the rear glass, a Phillips screwdriver to remove the chassis screws, and double-sided adhesive strips to close the device.

Points of caution before installation

The Galaxy A80 is disassembled from the rear: the rear glass detaches after moderate heating with a heat gun or hair dryer. Too high a temperature damages the rotating mechanism of the camera sensor, the most fragile part of this device. Work at 60-70°C maximum and slide the spudger gradually, without forcing on the side clips.

Disconnect the old battery before removing any screw: a short circuit on the power flex cable instantly burns out the charging circuit. Handle the new cell by the edges, never by the center where the pressure-sensitive electrodes are located.

Component warranty and stability

This battery is covered by a 2-year warranty against any manufacturing defect or premature capacity loss. Upstream quality control eliminates unstable batches and cells with a failure rate above the tolerated threshold. You benefit from a reliable alternative to manufacturer prices, validated for professional workshop use as well as personal repair.
