Compatibility
This battery fits the Samsung Galaxy S8 Plus (SM-G955F) only. It does not fit the Galaxy S8 (SM-G950F), Galaxy S9 Plus or Galaxy Note 8, which take their own batteries. The S8 Plus is taller than the standard S8, and although the S9 Plus looks similar, its camera layout and body differ. Check your model number in Settings > About phone, where it is listed as the model number (for example SM-G955F).
What you need to replace a Galaxy S8 Plus battery
- New rear cover adhesive: the back panel is glued on, so you need a fresh adhesive seal, or a new rear battery cover, to close the phone.
- Battery adhesive strips: the old battery is stuck to the frame. New strips hold the new battery in place.
- Basic tools: heat source, suction cup, plastic picks and a small Phillips screwdriver.
Never lever against the battery with metal tools or puncture it. If the old battery is swollen, work slowly and dispose of it at a battery recycling point.

Frequently asked questions
Will this battery fit my Galaxy S8?
No. It is made for the Galaxy S8 Plus (SM-G955F) only. Galaxy S8 uses a different battery.
How do I know my Galaxy S8 Plus battery needs replacing?
Common signs are fast draining, sudden shutdowns at 10 to 30%, the phone getting hot while charging, or the back cover lifting because the battery has swollen.
Can I fit it myself?
Professional installation is recommended. Screens and small parts are delicate, so we recommend having this part fitted by a qualified repair technician. Damage caused during fitting is not a product fault.
Should I charge the new battery before use?
Fit it, then charge it fully before first use. Battery readings settle after a few full charge cycles.
When will my order be dispatched?
