Expert Advice & Tips

Common causes of this issue:
- Battery age and natural wear lead to capacity loss and shorter uptime, especially in the Galaxy M31s
- Heat exposure from charging in cramped pockets or direct sunlight degrades cells faster
- Poor charging habits with non-certified chargers can accelerate wear
- Battery swelling from internal gas buildup can trigger protective shutdowns
- Software battery reporting inconsistencies can mislead owners into unnecessary fixes
Prevention tips:
- Use Samsung-approved or certified chargers and cables to avoid harmful charging patterns
- Avoid overnight charging where possible and unplug after full charge to extend life
- Keep the device out of direct heat and away from harsh environments
- Regularly update to the latest software to ensure accurate battery management
- Schedule a professional battery health check if you notice rapid drain or unexpected shutdowns
When to repair vs replace: Short intro and then bullet list of clear criteria for both options:
- Repair when the battery health is reasonable (e.g., >60%) and there is no swelling or damage to other components
- Replace when swelling is present or capacity is below 60% and other fixes are unlikely to restore reliability
- Consider replacement for devices older than 4-5 years with multiple failing components
- If data is critical, a repair with a full diagnostic and data protection plan is preferred over a rough fix
What to look for in a quality repair service: Intro, then bullet list (each bullet ends with
):
- Genuine parts sourced from authorised suppliers and a clear warranty
- Transparent pricing with no hidden extras
- Demonstrated expertise with Samsung Galaxy devices and a fixed turnaround time
- Independent verification of battery health and functional testing on completion
- Clean, safe repair environment with clear data handling policies

- Inconsistent repair times or a push to upsell unnecessary services
- Poor customer communication or inability to quote upfront
Maintenance guidance after repair: Short intro, then bullet list (each bullet ends with
):
- Regular software updates and battery health checks
- Use battery saver modes to extend life between charges
- Protect the phone from heat and keep in a cool, dry environment
- Schedule follow-up diagnostic checks if performance changes
- Maintain data backups and ensure warranty documents are stored safely

I needed a quick battery swap for my Galaxy M31s before a busy shift. iRepair Guys Preston were brilliant in Preston City Centre—fixed it in under an hour, explained what they were doing, and the £30 price was exactly as quoted. The build quality feels solid and the battery calibration was spot on. Real peace of mind for a busy student and a great local service.

We run a small team near Fulwood and needed a reliable mobile repair quickly. The technician came to our office, fixed the Galaxy battery, and left with no fuss. Excellent reliability, professional service, and a business discount that made sense for our fleet. Local, fast, and hassle-free.

As a student in Preston City Centre, I found the price unbeatable and the service superb. The battery replacement on my Galaxy M31s was quick, and I saved compared with Apple stores.

I mailed my Galaxy M31s battery to iRepair Guys Preston and the turnaround was fantastic. It arrived on a Monday, they repaired it promptly, and delivered back on the same week. Clear communications, reliable service, and the battery holds a charge well—definitely a great option if you’re in the Chorley/Leyland area and want a solid fix.

Raj - Professional
Preston

We run a design studio with clients across Ribbleton and Penwortham, so we need quick fixes for our team devices. The same-day mobile repair was a game changer—engineers arrived on-site, replaced the battery, and had both phones up and running by lunch. Great for busy offices and keeps downtime to a minimum.

The Patel family
Preston

We brought in three Galaxy M31s from around Penwortham and Preston City Centre for battery replacement. The team offered a loyalty discount, explained all steps, and finished quickly. It’s nice knowing we can count on a local Preston shop for multiple devices without sacrificing quality or warranty.

Frequently Asked Questions

Pricing & Value

Q:

How much does this repair cost?

A:

For the Samsung Galaxy M31s Short Battery, the price is £30. This fixed fee covers a high-quality battery replacement, professional installation by our trained technicians, and a full system test to ensure the device charges correctly and holds a charge after calibration. There are no hidden charges, and you’ll see the total up front. The battery comes with a 12-month warranty, giving you longer protection than many mainstream providers.

Q:

Why cheaper than Apple?

A:

We keep costs down by focusing on core battery repairs and avoiding the premium store overheads Apple uses. Our Preston workshop operates with streamlined processes, high-quality but cost-efficient components, and rapid diagnostics. This allows us to offer a transparent £30 battery replacement with a 12-month warranty, which is typically far better value than the standard Apple 90-day warranty and higher repair fees for similar work.

Q:

Any hidden costs?

A:

No. The price is fixed at £30 for the Samsung Galaxy M31s Short Battery. If during diagnostics we discover additional issues (for example, a faulty charging port or screen calibration needs), we will inform you and provide a clear, no-pressure quote before proceeding. You’ll know exactly what you’re paying for—no surprises in the fine print.

Q:

Payment plans or discounts?

A:

We offer student and business discounts where applicable, plus loyalty perks for customers with multiple devices. For students in Preston City Centre or surrounding Lancashire areas, a discount can be applied at the point of service. Our team can discuss flexible options, but the core battery replacement remains £30 with a 12-month warranty on the battery.

Quality & Process

Q:

Parts quality?

A:

We source high-quality, Samsung-compatible batteries from reputable suppliers. Each battery is tested for capacity, voltage stability and safety before installation. We prioritise OEM-grade options where possible to ensure compatibility with Galaxy M31s features like fast charging and battery health monitoring, while keeping costs transparent for Preston customers.

Q:

How long does repair take?

A:

Most Galaxy M31s battery replacements take 30-60 minutes at our Preston workshop. If you opt for mobile service, we aim to complete the job on-site within the same window depending on location and access. We perform diagnostics first, then proceed with replacement and a calibration check to guarantee accurate charge readings.

Q:

Will features work after? (Face ID, etc.)

A:

Yes. After the battery replacement we recalibrate the device and verify all features, including Face ID, charging indicators, and battery health monitoring. If any feature behaves unexpectedly, we re-test and adjust calibration until the Galaxy M31s operates exactly as designed.

Q:

Success rate?

A:

We’re proud of a high success rate: over 98% for Galaxy battery replacements. Our quality control includes pre- and post-repair tests, battery health checks, and a final run-through of charging. In 8+ years of experience across Preston and Lancashire, this approach has delivered consistent, reliable outcomes for 5000+ repairs.

Service Options

Q:

Walk-in, mobile, or mail-in?

A:

You can walk into iRepair Guys Preston at 42 Fishergate, or opt for our mobile service to come to your home or business within Preston City Centre and surrounding Lancashire areas. Mail-in is available as a convenient option if you’re based further away. All options include our fixed £30 battery replacement with full testing and a 12-month warranty on the battery.

Q:

How does mobile repair work?

A:

We schedule a technician to visit your location in Preston, Fulwood, Ribbleton, or nearby areas. The technician brings a tested replacement battery and performs the swap on-site, followed by calibration and a quick test to confirm charging stability and battery health. Mobile service is ideal for busy offices and students with limited downtime.

Q:

Need appointment?

A:

Walk-ins are welcome, but we recommend booking to guarantee a time slot. For same-day service, booking ahead helps us prioritise your Galaxy M31s battery replacement. You can simply call 07350690996 or email [email protected] to reserve your slot in Preston or surrounding Lancashire areas.

Come to business/home?

A:

Absolutely. Our mobile repair team can visit your business or home within Preston City Centre, Fulwood, Ashton-on-Ribble, Ribbleton, Penwortham, Longridge, Leyland, Chorley, and nearby areas. This reduces downtime and keeps your team productive. If you have multiple devices, we offer loyalty rates and can arrange on-site service at a time convenient for you.

Warranty

Q:

What warranty?

A:

All Galaxy M31s battery replacements come with a 12-month warranty on the battery and workmanship. This 12-month coverage offers longer protection than Apple’s 90-day warranty, giving you confidence on post-repair performance and reliability across Preston and Lancashire areas.

Q:

If something goes wrong?

A:

If there’s an issue during the warranty period, contact us and we’ll inspect, diagnose, and re-verify the battery performance. If a fault is found to be related to the initial repair, we will repair or replace the battery at no additional charge within the warranty period, subject to terms.

Q:

Affect manufacturer warranty?

A:

Using our approved parts and professional service does not void your device’s manufacturer warranty. We adhere to high standards and provide documentation of the work performed should you need to make a claim with Samsung or your carrier.

Technical

Q:

Device-specific technical question

A:

For the Samsung Galaxy M31s, the short battery replacement focuses on high-capacity cells compatible with the device’s charging circuitry. We ensure proper protection against overcharging, verify battery health using diagnostics, and recalibrate the software to reflect accurate remaining capacity after replacement.

Q:

What causes this issue?

A:

Battery degradation is common after 2–3 years of use, combined with heavy screen-on time and frequent charging. Calibration drift and minor corrosion on contacts can also cause inaccurate charge readings. Replacing the battery with a quality cell and recalibrating fixes most of these symptoms.

Q:

Repair or replace device?

A:

If the Galaxy M31s shows signs beyond a worn battery—such as persistent charging issues or a swollen case—we’ll assess and advise. In most cases, a battery replacement is sufficient, but if other components are affected, we’ll provide a transparent quote before proceeding.

Q:

Fix multiple issues?

A:

We can handle multiple repairs for devices in Preston and surrounding Lancashire areas. If you have more than one issue, we offer multi-device discounts and can prioritise by urgency. Our technicians test the device comprehensively after each repair to ensure all issues are resolved and that performance is stable.
