Huawei Battery Replacement Cost and Guide

A Huawei battery replacement costs from £6.99 to £7.99 for the battery itself at The Repair Plus for popular models such as the P30 Lite, P20 Pro, Mate 10, P Smart and Nova ranges (checked 15 October 2026). If you fit it yourself, add only adhesive and basic tools; a repair shop adds labour, and Huawei's official service usually costs the most. Most Huawei phones are opened from the back by heating and lifting the rear glass or plastic cover, then the battery is disconnected and carefully released from its adhesive. This guide shows how to find the right battery for your model, check whether it needs replacing, compare costs and replace it safely.

Huawei battery prices by model

Many Huawei batteries fit several models, because Huawei and Honor shared batteries across phones. These are the replacement batteries listed at The Repair Plus on 15 October 2026. Always check your exact model against the listing before ordering.

How much does a Huawei battery replacement cost?

For the models above, the battery costs £6.99 to £7.99 (checked 15 October 2026). DIY adds only adhesive and tools; a local repair shop adds a labour charge; Huawei's official service charges its own price per model, usually the highest of the three but with manufacturer parts and warranty.

We have not quoted shop or official prices because they vary by model and over time. Huawei's UK support site lists official service options.

How do I check Huawei battery health?

Many Huawei phones do not show a battery health percentage in Settings. Use the battery usage screen to spot unusual drain, and run the diagnostics in Huawei's support app where available. A phone that dies quickly, shuts down at mid-charge or swells needs a new battery.

• Settings > Battery: shows usage by app and the battery level graph. A steep, steady drop with little screen time suggests a worn battery.
• Support app diagnostics: Huawei's support app (named My HUAWEI or Support on different versions) includes a smart diagnosis tool on many models that checks the battery.
• Physical signs: a back cover lifting, a screen bulging or a phone that rocks on a flat table can mean the battery is swelling. Stop using and charging the phone straight away.

Signs you need a new battery

• The phone no longer lasts a normal day.
• It shuts down at 20–30%, especially in the cold.
• The percentage jumps or drops suddenly.
• It only works when plugged in.
• It feels hot during light use or while charging slowly.
• The case or back cover is bulging.

Before replacing, rule out software: update the phone, check Settings > Battery for an app using unusual power, and restart.

Finding the right battery for your Huawei

1. Find your model in Settings > About phone. Note both the marketing name and the model code.
2. Match it to a listing that names your model. Shared batteries are common, but similar names, such as P20 Lite and P20 Lite (2019), can use different batteries.
3. Check the capacity and connector match the listing.
4. Buy back-cover adhesive for your model if your phone has a glued back.

Preparing for the repair

A little preparation makes the job safer and quicker. Back up photos, contacts and messages first; a battery swap should not affect your data, but a backup removes the worry. Clear a well-lit table, lay down a soft cloth to protect the back glass and screen, and keep a small dish or magnetic mat for each group of screws. Take photos as you go, especially of cable positions and the order of covers, so reassembly is straightforward. Have the isopropyl alcohol and plastic card ready before you start releasing the battery, because that is the stage where patience matters most. Finally, check you have back-cover adhesive for your exact model: generic sheets can be cut to shape, but pre-cut adhesive gives a neater, more even seal.

Tools you need

• Heat source: heat pad, hairdryer or heat gun on a low setting
• Suction cup and thin plastic opening picks
• Phillips #00 screwdriver
• Plastic spudger and tweezers
• Plastic card for lifting the battery
• Isopropyl alcohol
• Back-cover adhesive and battery adhesive strips
• Safety glasses

How do I change a Huawei battery?

On most Huawei phones you heat and remove the back cover, unscrew the midframe or board cover, disconnect the battery, release it from its adhesive with alcohol and a plastic card, fit the new battery and reassemble with new back adhesive. The steps below are general; layouts vary by model.

1. Back up your data and discharge the battery below 25%. Power off and remove the SIM tray.
2. Heat the back cover edges evenly until warm to the touch.
3. Lift a corner with a suction cup and insert an opening pick. Work around the edges slowly, reheating as needed. Glass backs can crack; go gently.
4. Watch for the fingerprint sensor cable on models with a rear fingerprint reader. Lift the back only slightly until you find and disconnect it.
5. Remove the screws holding the midframe, wireless charging coil or NFC antenna cover.
6. Disconnect the battery connector with a plastic spudger before anything else.
7. Release the battery. If it has pull tabs, pull slowly and low. If not, apply a few drops of isopropyl alcohol around the edges, wait a minute, and lift gently with a plastic card. Never use metal tools and never bend the battery.
8. Clean the battery bay and fit new adhesive.
9. Place the new battery, connect it, and refit the covers and screws.
10. Test: power on, check charging, fingerprint sensor, cameras and NFC.
11. Fit new back-cover adhesive and press the cover into place. Clamp gently while it bonds.
12. Charge to 100% without interruption before normal use.

Is it worth replacing the battery in an old Huawei?

Usually yes for a part under £8, especially if the phone is otherwise in good condition and does what you need. Be aware that newer Huawei phones sold in the UK do not include Google services, and older models eventually stop receiving security updates, so check your model's status before investing in other repairs.

A new battery is one of the most cost-effective repairs on any phone: it restores day-long use, reduces unexpected shutdowns and keeps a working phone in use for longer. If the screen is also damaged, it may be worth doing both jobs together, because the phone is already open.

How can I save battery on a Huawei phone?

Use Power saving mode on long days, lower screen brightness or use adaptive brightness, enable dark mode on OLED models, restrict background activity for apps you rarely use and avoid heat. These steps reduce daily drain and slow long-term wear.

• Power saving mode in Settings > Battery limits background activity.
• App launch management on EMUI lets you stop apps running in the background.
• Avoid charging in hot places such as on a car dashboard or under a pillow.
• Keep software updated where your model still receives updates.

Troubleshooting after the replacement

Most problems after a battery swap are caused by a connector that is not fully seated or a cable disturbed while the phone was open. Check these before closing the back cover for good.

• Phone does not power on: new batteries often ship part-charged. Connect a charger for 15 minutes, then try again. If nothing happens, reseat the battery connector.
• Fingerprint sensor not working: on rear-sensor models the small flex cable on the back cover is easy to leave unplugged. Reconnect it before sealing.
• NFC or wireless charging not working: the antenna or coil cover may not be seated, or its contacts may be bent. Refit it carefully.
• Battery percentage unreliable: allow a few full charge and discharge cycles for the phone to recalibrate.
• Back cover not sitting flat: old adhesive or a trapped cable is usually the cause. Remove, clean and refit with fresh adhesive.

Using a repair shop instead

If you would rather not open the phone, a local repairer can usually swap a Huawei battery quickly. Ask for an itemised quote showing the battery and labour, check which battery they fit and what warranty covers it, and confirm that new back-cover adhesive is included. Some shops will fit a battery you have bought; ask first, because policies vary. Back up your data and remove your SIM and memory card before handing the phone over.

Keeping an older Huawei secure

A new battery can give an older phone years of extra use, but security matters too. Check Settings > System > Software update to see whether your model still receives updates. If updates have stopped, consider using the phone for less sensitive tasks, such as music, a sat-nav or a child's phone with basic apps, rather than banking. Keep apps updated from the store you use, and avoid installing apps from unknown sources.

Safety and disposal

Lithium-ion batteries can catch fire if punctured, bent or short-circuited. Work on a non-flammable surface and never heat a swollen battery. The charity Electrical Safety First publishes battery safety guidance. Dispose of old batteries at a battery recycling point, as GOV.UK's waste batteries guidance explains; tape over the terminals first.

Common mistakes

• Ordering by a similar model name. Check the listing names your exact model.
• Tearing the fingerprint cable when lifting the back cover.
• Not disconnecting the battery before other work.
• Prying the battery with metal tools.
• Reusing old back-cover adhesive, which leaves gaps and lets dust in.
• Overheating glass backs, which can crack or delaminate.
