Compatibility
This battery fits the Samsung Galaxy S9 Plus (SM-G965F) only. It does not fit the Galaxy S9 (SM-G960F), Galaxy S8 Plus or Galaxy S10 Plus, which take their own batteries. The S9 Plus has a dual rear camera and a taller body than the standard S9, so parts are specific to each phone. Check your model number in Settings > About phone, where it is listed as the model number (for example SM-G965F).
What you need to replace a Galaxy S9 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.
Disconnect the battery connector before any other work, use plastic tools only and take any swollen battery to a recycling point rather than the household bin.

Frequently asked questions
Will this battery fit my Galaxy S9?
No. It is made for the Galaxy S9 Plus (SM-G965F) only. Galaxy S9 uses a different battery.
How do I know my Galaxy S9 Plus battery needs replacing?
If the phone switches off with charge left, drains overnight, or the back panel has started to bulge, the battery is worn and should be replaced.
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.
