Battery Replacement FAQ
How long does battery replacement take?
Most battery replacements are completed within 30 to 45 minutes while you wait at either of our Muthupet shops on PKT Road. You can sit comfortably in our shop or run a quick errand in Koyyah Bazaar while our technician installs the new cell.
Will a new battery make my phone like new?
A genuine replacement battery will restore your phone's battery life to close to original capacity. If your phone feels slow, that may be a separate software or processor issue. A battery replacement solves battery-specific problems like fast draining and sudden shutdowns.
My phone battery is swollen — is it dangerous?
Yes. A swollen battery is a safety hazard. Stop charging the phone immediately. Do not press on the swelling. Bring it to us as soon as possible. We will safely remove and replace the swollen battery. Do not delay on this, as it poses a serious fire risk.
Do you use original batteries?
Smart Mobiles uses quality replacement batteries compatible with your phone model. We do not use the cheapest available batteries, which degrade within a few weeks. We will tell you about the battery options and let you decide before we replace it.
