Battery replacement for Samsung Galaxy S21 FE — price €85. We repair your phone and ship it back within 24 hours of receiving it.
Phone draining fast or shutting itself off? We'll replace the battery.
When do you need a battery replacement?
- The phone no longer lasts a day of normal use, although it used to.
- The percentage drops in jumps, or the phone shuts down at 20–30%.
- It switches off in the cold, or when taking photos and running demanding apps.
- The back cover or display is bulging — don't wait, a swollen battery is a safety risk.
Looks like you need a battery replacement, but the cause is often elsewhere
- Charges slowly or only with the cable at an angle — that's the charging port, not the battery.
- Drains fast only since the last update or with one app — more likely software; try a restart and check app battery usage.
- Won't turn on at all, even on the charger — could be the board or the port.
- If you're not sure, choose Diagnostics — we'll send you the exact repair price within 24 hours of receiving your phone. Diagnostics are free if you approve the repair; if you decline, we charge €35 for diagnostics and shipping the phone back.
How the repair works
- We fit a new full-capacity battery and recycle the old one.
- On Samsung phones the battery is glued in under the back cover (glass or plastic, depending on the model) — we replace it without damaging the cover and re-bond the cover with a fresh seal.
- €85 is the final price: part and labour, no hidden fees.
- Done within 24 hours of receiving your phone.
- 12-month warranty on the battery and the work.
If you leave it
A worn battery shuts the phone down at the worst moment and can swell when it overheats — a swollen battery pushes on the display and back glass and damages them. A €85 replacement is cheaper than adding a display to it.
