5 Signs Your iPhone Battery Needs Replacing (And What to Do About It)

5 Signs Your iPhone Battery Needs Replacing (And What to Do About It)

Your iPhone is one of the most important tools you carry every day. But no matter which model you own — whether it’s an iPhone 14, iPhone 15 Pro, or the latest iPhone 16 — the battery will degrade over time. Apple designs iPhone batteries to retain up to 80% of their original capacity after 500 full charge cycles. After that, performance can drop noticeably.

The good news? A battery replacement is one of the most affordable and impactful repairs you can make. At Phone Heroes in Earl’s Court, we replace iPhone batteries in as little as 30 minutes — and your phone will feel like new again.

Here are five clear signs that your iPhone battery needs replacing.

1. Your iPhone Is Draining Much Faster Than It Used To

This is the most common complaint we hear at our Earl’s Court repair shop. If your iPhone used to last all day on a single charge but now needs a top-up by early afternoon, that’s a strong indicator that your battery health has declined.

To check your battery health, go to Settings > Battery > Battery Health & Charging. If the maximum capacity reading is below 80%, Apple itself recommends a replacement. Anything below 85% and you’re likely already noticing reduced performance.

A degraded battery won’t just drain faster — it can also cause your iPhone to run warmer than usual and trigger unexpected behaviours across apps.

2. Your iPhone Shuts Down Unexpectedly — Even With Battery Remaining

One of the most frustrating symptoms of a failing battery is your iPhone powering off suddenly — even when it shows 20%, 30%, or more battery remaining. This happens because an aged battery can no longer deliver the peak power that the iPhone’s processor demands under load.

When the battery can’t sustain the power draw, your iPhone shuts itself down as a protective measure. If this is happening to you regularly, a battery replacement is almost certainly the solution.

This issue tends to get worse in cold weather, when battery chemistry performs less efficiently — another sign the cells are past their best.

3. Your iPhone Is Slower Than It Used to Be

Apple introduced a feature called performance management, which automatically reduces your iPhone’s processor speed to prevent unexpected shutdowns caused by an ageing battery. While this protects the hardware, it means your phone may feel sluggish — apps take longer to open, animations stutter, and the camera is slower to respond.

Many people assume their iPhone is just getting old and start thinking about an upgrade. In many cases, a simple battery replacement is all that’s needed to restore full speed and responsiveness. At Phone Heroes, customers are often amazed at how much faster their phone feels after a battery swap.

You can check whether performance management is active on your device by going to Settings > Battery > Battery Health & Charging and looking for any performance management notices.

4. Your iPhone Gets Unusually Hot During Normal Use

It’s normal for your iPhone to get slightly warm during intensive tasks — gaming, video calls, or using GPS for long periods. But if your device regularly feels hot during everyday tasks like browsing, messaging, or streaming, the battery may be to blame.

An ageing lithium-ion battery has to work harder to deliver the same power output, generating more heat in the process. Excessive heat can also accelerate the degradation of other components over time — so it’s worth addressing sooner rather than later.

If your iPhone is running warm alongside any of the other symptoms on this list, a battery replacement should be your first step.

5. Your Battery Health Is Below 80% — Even If You Haven’t Noticed Symptoms Yet

Sometimes battery degradation is gradual enough that you adapt to it without realising. You start charging more frequently, you carry a portable power bank, or you just accept that your phone doesn’t last as long as it used to.

If you check your Battery Health and see a reading below 80%, we’d recommend replacing the battery even if you haven’t noticed dramatic symptoms yet. Proactive replacement means you won’t be caught short during a busy day — and it’s far cheaper than buying a new phone.

At Phone Heroes in Earl’s Court, iPhone battery replacements start from £39 and take around 30 minutes. We use high-quality replacement batteries and back every repair with a one-year warranty.

iPhone Screen Repair: Apple Store vs Independent Repair Shop — Which Should You Choose?

iPhone Screen Repair: Apple Store vs Independent Repair Shop — Which Should You Choose?

Cracking your iPhone screen is one of those moments that instantly ruins your day. Within seconds, you’re weighing up your options — and the two you’re most likely to consider are the Apple Store and an independent repair shop.

Both have their merits. But which is actually the better choice for most people? At Phone Heroes in Earl’s Court, we’ve repaired thousands of iPhone screens — and we want to give you an honest, balanced answer so you can make the right decision for your situation.

Here’s how the Apple Store and an independent repair shop compare across the five factors that matter most.

1. Cost — How Much Will You Pay?

This is usually where the difference is most stark. Apple charges premium prices for screen repairs, particularly on newer models. An out-of-warranty iPhone 15 Pro screen repair at the Apple Store can cost upwards of £300. For an iPhone 16 Pro Max, that figure can exceed £400.

At an independent repair shop like Phone Heroes, iPhone screen repairs start from £49 for older models, and even repairs on current flagship devices are significantly less expensive than Apple’s out-of-warranty pricing.

The exception is if you have AppleCare+, which reduces Apple’s repair fees considerably — sometimes to as little as £25. If you have an active AppleCare+ plan, the Apple Store becomes much more competitive on price.

For the majority of iPhone owners without AppleCare+, an independent repair shop offers dramatically better value.

2. Speed — How Long Will You Wait?

Apple Store appointments are typically booked days in advance — sometimes a week or more if your local store is busy. Once you’re in, the repair itself may take several hours or require you to leave your phone overnight.

At most independent repair shops, you can walk in without an appointment and have your screen replaced in 30 to 60 minutes. At Phone Heroes in Earl’s Court, the majority of iPhone screen replacements are completed while you wait — often in under an hour.

If you need your phone back quickly and can’t afford to wait for an Apple Store slot, an independent repair shop is almost always the faster option.

3. Parts Quality — Will the Repair Be as Good?

This is the question people ask most often — and it deserves a straight answer. Apple uses original Apple-manufactured screens, which do offer some technical advantages, particularly around True Tone calibration and Face ID compatibility.

Reputable independent repair shops use high-quality aftermarket or OEM-equivalent panels that deliver excellent display performance in everyday use. The difference in real-world quality between a good aftermarket screen and an Apple original is often indistinguishable to most users.

Where quality can vary is between repair shops — not all independents use the same grade of parts. At Phone Heroes, we use premium-quality screens and are transparent about the options available to you. We’ll always tell you what grade of screen is being fitted and what to expect.

The key is to choose a repair shop with a track record of quality and a warranty to back it up.

4. Warranty — What Happens If Something Goes Wrong?

Apple provides a 90-day warranty on its out-of-warranty repairs — covering only the repair itself, not any unrelated issues.

At Phone Heroes, every screen repair comes with a one-year warranty as standard — more than four times the coverage Apple provides on out-of-warranty fixes. If the same issue returns within 12 months of your repair, we fix it at no charge.

For most customers, a one-year warranty from a trusted local repair shop provides more than adequate peace of mind — and better protection than Apple’s own terms on paid repairs.

5. Convenience — Which Is Easier to Access?

The nearest Apple Store to Earl’s Court is in Covent Garden or Westfield Shepherd’s Bush — both requiring travel, a booked appointment, and significant time out of your day.

Phone Heroes is located at the Warwick Road Entrance of Earl’s Court Underground Station — one of West London’s most accessible locations. If you live or work in Kensington, Chelsea, Fulham, Hammersmith, or anywhere nearby, we’re easy to reach without going out of your way.

Walk in during opening hours and you’ll be back on your way with a repaired phone in under an hour — no appointment, no travel across London, no waiting.

So — Which Should You Choose?

Choose the Apple Store if you have AppleCare+ (the reduced price makes it excellent value) or if your iPhone is still under its original one-year Apple warranty.

Choose an independent repair shop like Phone Heroes if your iPhone is out of warranty, you need your phone repaired quickly, or you want a high-quality repair at a fair price without trekking across London.

At Phone Heroes in Earl’s Court, we’ve built our reputation on delivering repairs that last — with honest pricing, premium parts, and a one-year warranty on everything we touch. Call us on 020 3397 7407, visit phoneheroeslondon.co.uk, or simply walk in to our shop at Earl’s Court Station.
