How much to change a vivo X21 UD battery in Singapore?

S$30 nett for the Grade AAA option. That's what you pay at the counter — the price on this page is the price, with nothing added to it, and it was last checked 11 Sep 2026. Message us and we'll confirm the cover on this one before you come down.

How do I know my vivo X21 UD needs a new battery?

The signs are the ones you notice without any app: it drops 20% while sitting in your pocket, it shuts off at 30%, or it gets hot on the charger. On Samsung, Settings › Battery and device care › Battery shows you the health reading. Most vivo X21 UD batteries start doing this past the two-year mark. A swollen battery is the urgent case — if the screen or back is lifting at an edge, stop charging it and bring the phone in.

How long does it take to change a vivo X21 UD battery?

Same day for most vivo X21 UD jobs, often within the hour. Send us a message first so we can check the battery for your model is in stock — that's what turns a wait into a second trip.

What is Grade AAA, and how is it different from an original battery?

Grade AAA is a high-grade aftermarket part rather than an original-spec one. It's built to the same fit and function, with capacity close to the original cell but not always identical, and it costs noticeably less — that's the whole point of the grade. We name the grade next to the price rather than leaving you to ask, and the grades are set out in full here.

Do you wipe the vivo X21 UD, and do you need my passcode?

No, nothing gets wiped. Your photos, apps, messages and settings stay exactly where they are — a battery replacement doesn't touch storage. We ask for a passcode only to test the phone after the repair; if you'd rather not hand it over, unlock it for us at the counter and stay while we check. A backup before you hand it over is still sensible, because that's true before anyone opens a phone.

Where can I get same-day vivo X21 UD battery replacement in Singapore?

At any of our four shops — Chinatown, Tampines, Jurong and Yishun — open 11am–9pm daily, no appointment needed.
