The S26 carries a 4300mAh battery, a step up in capacity from the S25 before it. It is young now, but every lithium cell wears with charge cycles, and heavy chargers get through cycles quickly.

When the day no longer fits on one charge, we fit the original Samsung battery at our Umhlanga centre. The cell and the fitting are included in the price shown, and we will gladly test the battery first if you are unsure.

Common questions

My S26 is quite new but the battery drains fast. Is the cell faulty?

Not necessarily. On a newish phone, heavy drain is more often an app, a weak signal area or settings than a worn cell. Run the diagnostics in Samsung Members and check battery usage per app first. If the hardware test flags the cell, replacement is the answer.

What wears a battery out fastest?

Heat and cycles. Leaving the phone in a hot car, gaming while charging and running flat to zero every day all age the chemistry faster. The wear is gradual and irreversible, which is why replacement is the fix once capacity has genuinely dropped. Good habits slow it, nothing undoes it.

Do you use original Samsung batteries for the S26?

Only original. We are an authorised Samsung service centre, and the battery fitted to your S26 is the genuine Samsung part for this model. It matches the phone's capacity and charging profile exactly, and the fitting by our technicians is part of the price shown.
