Questions and Answers
Is the battery a genuine Apple part? As Apple no longer manufactures parts for the 3G/3GS, we use premium compatible batteries that match the original capacity and safety standards perfectly.
Will I lose my photos? A battery change does not affect the storage, so your data is safe. However, we always advise a backup for total peace of mind.
How long will the new battery last? With proper care, the new battery should last for several years, similar to the original when it was new.
