How We Handle It

A worn battery affects more than screen-on time. iOS deliberately slows the processor when the battery can no longer deliver peak current, so an ageing battery often shows up as a "slow iPhone" rather than an obviously weak one. If your iPhone feels sluggish and battery health has dropped, a battery replacement is usually the most cost-effective fix.

Swollen batteries deserve special mention: if your screen is lifting away from the frame or the back glass is bulging, stop using the phone and avoid charging it. Bring it in — we remove swollen cells safely and check for any damage they may have caused to the display or housing.

Every battery replacement at iFix Guwahati ends with a verification pass: we confirm the phone charges correctly, holds a stable connection with the charger, and reports battery status properly in Settings.
