Battery for Galaxy S3

The Cameron & Co DS-CS-SMI930HL is a lithium-ion replacement battery built for the Samsung Galaxy S3 and S III i9300 series. It suits owners who need a fresh power source for daily calls, messaging and light app use.

Extended capacity with cover

The pack integrates a 3300 mAh cell rated at 3.7 V and 12.2 Wh inside a black back cover that replaces the original battery door. No extra cables or adapters are required; the unit slots directly into the handset and restores the factory form factor.

Headroom for typical use

The higher capacity gives comfortable runtime for mixed screen-on time and standby, while heavy navigation or continuous video streaming will drain the cell faster. Buyers who want more storage or a second battery for hot-swapping should look elsewhere.

Does the battery run hot or drain quickly when the phone is used all day?

The pack fits the standard 63.00 x 50.00 x 10.00 mm bay and uses the same Li-ion chemistry as the factory battery, so thermal behaviour is identical.
