Phone Battery Replacement in the UK – Fast, Affordable & Same-Day Service

Is your phone battery draining faster than it used to? Struggling to make it through the day without hunting for a charger? You are not alone. Battery degradation is one of the most common problems smartphone users face in the UK – and the good news is you do not need to buy a new phone to fix it.

At iExpert Repairs, we provide professional phone battery replacement across Southend-on-Sea, Essex, and London. Whether you have an iPhone, Samsung Galaxy, Google Pixel, or Huawei, our certified technicians replace your battery the same day – usually in under an hour.

No appointments needed. No data loss. Full warranty included.

Signs Your Phone Battery Needs Replacing

Not sure if your battery is the problem? Here are the most common warning signs that tell you it is time for a phone battery replacement:

• Battery draining too fast – your phone loses charge in a few hours even with light use
• Unexpected shutdowns – the phone switches off at 20-30% charge without warning
• Slow performance – your device feels sluggish or laggy, especially on older models
• Overheating – the phone gets unusually warm during normal use or while charging
• Swollen battery – the back of your phone is bulging or the screen is lifting (replace immediately – this is a safety risk)
• Stuck on charge – your phone takes hours to charge or will not charge at all
• Low battery health – iPhone users can check under Settings > Battery > Battery Health. If it reads below 80%, a replacement is recommended

If you are experiencing any of these issues, a battery replacement will restore your phone to near-original performance at a fraction of the cost of a new device.

How Much Does Phone Battery Replacement Cost in the UK?

Phone battery replacement in the UK is far more affordable than most people expect — and significantly cheaper than going directly to Apple or Samsung.

All prices include premium-grade replacement battery, fitting by a certified technician, and a repair warranty. We also offer Fix Now, Pay Later with Klarna so you can spread the cost into flexible instalments.

Phone Battery Replacement by Brand – iPhone, Samsung, Google Pixel & More

iPhone Battery Replacement – All Models from iPhone 6 to iPhone 17

iPhone batteries degrade over time with every charge cycle. Apple recommends replacing your battery when health drops below 80% – at which point iOS may also throttle your phone’s performance to prevent unexpected shutdowns.

At iExpert Repairs, we replace batteries across the full iPhone range:

• iPhone 11 & 11 Pro – from £49
• iPhone 12 & 12 Pro – from £59
• iPhone 13 & 13 Pro – from £65

How to check your iPhone battery health: go to Settings > Battery > Battery Health & Charging. If the percentage is below 80%, book your replacement today. All iPhone battery replacements at iExpert are completed using high-quality OEM-equivalent cells and take approximately 45-60 minutes.

Samsung Battery Replacement – Galaxy S & A Series

Samsung Galaxy phones use lithium-ion batteries that typically last 2-3 years under normal use. When your Samsung is no longer holding charge, draining overnight, or shutting down unexpectedly, a battery replacement is the quickest and most cost-effective fix.

We replace batteries in all major Samsung models including:

• Samsung Galaxy A14, A34, A54, A55 – from £39
• Samsung Galaxy S22, S23, S24 – from £55
• Samsung Galaxy S22 Ultra, S23 Ultra – from £59
• Samsung Galaxy Z Fold & Z Flip – from £69

To check battery health on a Samsung Galaxy: dial *#0228# in the phone app, or go to Settings > Battery > Battery Care.

Our Samsung battery replacements are carried out by trained technicians using premium-grade cells, with same-day service available.

Google Pixel Battery Replacement

Google Pixel phones are known for their clean software and camera quality – but like all smartphones, their batteries degrade with use. Pixel users often report battery drain increasing sharply after 18-24 months.

We offer battery replacement for:

• Google Pixel 6 & 6 Pro – from £49
• Google Pixel 7 & 7 Pro – from £55
• Google Pixel 8 & 8 Pro – from £59
• Google Pixel 9 & 9 Pro – from £69

If your Huawei phone is not lasting through the day or is overheating while charging, a new battery will make a significant difference to daily performance.

Is It Worth Replacing a Phone Battery Instead of Buying New?

In almost every case, yes. Here is why:

• A battery replacement costs £39-£65 depending on your device
• A new mid-range smartphone costs £300-£700
• A quality battery replacement extends your phone’s life by 2-3 years
• You keep all your data, settings, and apps without the hassle of switching

Repairing your phone is also the environmentally responsible choice. Electronic waste is one of the UK’s fastest-growing waste streams. Replacing a battery instead of discarding a working phone reduces your carbon footprint and supports a more sustainable approach to technology.
