7 signs your iPhone battery needs replacing
Every iPhone uses a lithium-ion battery, and every lithium-ion battery wears out over time. After a few hundred full charge cycles, it simply cannot hold as much power as it did when new. Here are the most common signs that it is time for a new battery:
- Fast draining: your phone drops from 100% to 20% in a few hours of normal use.
- Unexpected shutdowns: the iPhone switches off suddenly, even when it shows 20% or 30% left.
- Slow performance: apps take longer to open and the phone feels sluggish. iOS can slow the processor to protect an ageing battery.
- Overheating: the phone gets hot during light tasks such as messaging or browsing.
- "Service" message: iOS shows a warning under Battery Health recommending a service.
- Only works on charge: the iPhone needs to be plugged in to stay on.
- Swollen battery: the screen lifts or the back glass bulges. This is a safety issue, so stop charging the phone and book a repair straight away.
How to check your iPhone battery health
Before you book, it takes less than a minute to check how your battery is doing:
- Open Settings on your iPhone.
- Tap Battery, then Battery Health & Charging (on older iOS versions, just Battery Health).
- Look at the Maximum Capacity percentage.
A new battery shows 100%. Once it falls to around 80% or below, most people notice shorter battery life and occasional slowdowns, and this is generally the point where an iPhone battery replacement is recommended. If you see a "Service" message on this screen, iOS itself is telling you the battery has degraded.
Not sure what the numbers mean? Mention your battery health percentage when you request a quote, and our technician will advise you honestly on whether a replacement is worth it.

Tips to make your new iPhone battery last longer
Once your battery has been replaced, a few simple habits will help it stay healthy for years:
- Turn on Optimised Battery Charging in Settings so your iPhone avoids sitting at 100% overnight.
- Avoid extreme heat: do not leave your phone on a car dashboard or charge it under a pillow.
- Use quality chargers and cables: cheap, uncertified chargers can damage the battery and charging port.
- Keep iOS updated: Apple regularly improves battery management in software updates.
- Lower screen brightness or use Auto-Brightness and Dark Mode to reduce drain.
- Avoid draining to 0% regularly; topping up between 20% and 80% is kinder to lithium-ion cells.
Frequently asked questions
How long does an iPhone battery replacement take?
Most iPhone battery replacements take 30 to 60 minutes. Because we work at your location, you get your phone back the same visit, with no need to leave it at a shop.
How much does an iPhone battery replacement cost in West London?
The price depends on your iPhone model. Visit our Instant Quote & Pricing page for a clear, upfront quote with no hidden charges.
Will I lose my data during a battery replacement?
No. A battery replacement does not touch your storage, so your photos, contacts and apps stay exactly where they are. We still recommend an iCloud backup before any repair, just to be safe.
Which iPhone models do you replace batteries for?
We replace batteries on a wide range of iPhone models, from older devices to recent ones. Tell us your exact model when you request a quote and we will confirm availability.
Do you offer same-day iPhone battery replacement in Hounslow?
Yes, same-day appointments are often available in Hounslow, Uxbridge, Isleworth and the surrounding West London areas, depending on technician availability.
Is it safe to use a phone with a swollen battery?
No. A swollen battery can damage the screen and, in rare cases, become a fire risk. Stop charging the phone, keep it away from heat and book a replacement as soon as possible.
Can you come to my workplace?
Absolutely. Many customers book us at their office so the repair happens during a lunch break or between meetings.
How do I know if I need a battery or a charging port repair?
If your iPhone charges but drains fast, it is likely the battery. If it will not charge, or only charges at an angle, the charging port may be the problem. Our technician diagnoses this on-site before starting any work.
