Phone batteries wear out — it's normal. After a couple of years of daily charging they hold noticeably less than when new, and eventually the phone becomes a slave to the charger. The good news is a battery replacement is quick, affordable, and makes an otherwise good phone feel new again.
Tell-tale signs your battery is worn out
- It drains fast — you're topping up by lunchtime when you never used to.
- Sudden shutdowns — the phone dies at 20–40% even though there's "charge" left, and often more suddenly when it's cold.
- It gets hot — noticeably warm while charging or during light use.
- Slow or stuck charging, or the percentage jumping around.
- The phone feels sluggish — some phones deliberately slow down to cope with a tired battery.
- The back is lifting — a swollen battery pushes the screen or back panel up. Stop using it and bring it in promptly; that one's not worth leaving.
How to check on your phone
On an iPhone, Settings → Battery → Battery Health & Charging shows a "Maximum Capacity" figure — once it's dropped into the low 80s or below, a replacement makes a real difference, and Apple flags it as "Service" lower still. Many Android phones show similar battery information in Settings, or through the device's diagnostics menu — otherwise the signs above tell the story.
What a replacement involves
I fit a quality replacement battery, calibrate it, test it and seal the phone back up properly — usually the same day. Your phone holds a full charge again and stops the surprise shutdowns, covered by a 90-day warranty. Prices by model are on the phone screen & battery replacement page.
If the screen's seen better days too, it's worth doing both together — here's how to decide on a cracked screen. Book a repair or get in touch to get started.
