Battery replacements in Derry

Signs your battery needs replacing

• It drains far faster than it used to — a phone that used to last a full day now needs topping up by mid-afternoon.
• Sudden shutdowns at 20–40%, even though the phone claims it still has power. It often restarts when you plug it in.
• The percentage jumps around — 80% one minute, 12% the next, then back up again.
• It gets warm when it should not — hot while sitting idle, or unusually hot while charging.
• It only works on a charger, switching off the moment the cable comes out.
• Physical swelling. Look for a back panel or screen edge lifting away from the frame, a case that suddenly fits badly, or the phone rocking when it sits on a flat table.

What the repair involves

1. We confirm the battery is actually the problem Charging faults, a worn cable, debris in the charging port and software issues can all mimic a failing battery. We check those first and tell you honestly if a simpler, cheaper fix is the answer.
2. We assess the state of the phone Model, whether it has been opened before, whether the frame or screen has been pushed out of shape by swelling, and whether any old adhesive needs cleaned up.
3. You approve the price, part and timeframe We confirm what the replacement costs, whether the battery is on the shelf or needs ordered in, and how long the job will take.
4. The battery is replaced The handset is opened following the correct procedure for the model, the old cell is removed and disposed of properly, the frame is cleaned, and fresh adhesive is used to seal the phone back up where the model calls for it.
5. Testing before you collect Charging and fast-charging behaviour where the phone supports it, a check that nothing is running hot, and — on handsets that report one — a look at the battery health reading. Some phones need a charge cycle or two before that figure settles.

Asking about price, parts and turnaround

Battery prices vary between models, so we quote rather than publish figures. Ring +44 7955 584114 with:

• the make and model of the phone
• how it behaves — how quickly it drains, whether it shuts down suddenly, and whether you can see any swelling
• whether the phone has been opened or repaired anywhere before

Then ask us what the replacement costs, whether the battery is in stock at the shop or needs ordered in, and how long we would need the phone. Any estimate is confirmed with you before work begins.
