How to check your battery health right now

• iPhone: Settings > Battery > Battery Health & Charging. Below 80% is Apple's own threshold for "significantly degraded."
• Samsung Galaxy: Settings > Battery and device care > Battery > Battery status (available on most recent One UI versions), or via Samsung Members app diagnostics.
• Google Pixel: no built-in percentage tool on most models — judge by the symptoms below, or ask us to check for you.

5 signs you need a battery replacement

1. Random shutdowns above 0% charge, especially under load (camera, GPS, gaming).
2. Screen-on time has roughly halved compared with when the phone was new.
3. The phone runs noticeably warm during normal use or light charging.
4. Charging is slow, unreliable, or the percentage jumps unexpectedly.
5. Visible swelling anywhere on the back or around the screen edges — stop using the phone immediately and replace the battery; this is a genuine safety issue, not just a performance one.

How much does a phone battery replacement cost?

Across our current UK stock, genuine-quality replacement batteries range from £6.89 (Samsung Galaxy A series) to around £45 (latest-generation iPhone 16 Plus), with most popular models — iPhone 11 through 15, Galaxy S20/S21, and most Pixels — priced under £20. That's a fraction of any replacement phone, and it's the single most cost-effective repair you can make.

DIY vs professional replacement

Battery replacement is one of the more approachable phone repairs — a proper opening kit, care around the adhesive pull-tabs, and a steady hand are usually all it takes. If you'd rather not do it yourself, any local independent repairer can fit the part same-day; ask for a workmanship warranty on top of the part itself.

FAQ

Will a new battery make my old phone feel new again?

If battery life is your main complaint, yes — it's the single most effective fix for a phone that no longer lasts the day.

Is it safe to replace a phone battery myself?

Yes, with a proper opening kit and careful handling of the adhesive and cell. Avoid puncturing or bending the battery. If in doubt, book a professional fitting.

Does a third-party battery affect my warranty?

It can affect manufacturer coverage on the battery specifically. Check your warranty status before replacing if the phone is still new.
