Pros and cons

✓ Pros

  • 5200 mAh battery means no wiring needed at all
  • Runs on Type-C or hardwired 8-24V AC, so you can switch later
  • IP65 rated for rain on an exposed Philippine doorway
  • 2K sensor, a real step up from the 1080p Xiaomi model

✗ Cons

  • Ties you to the Mi Home app rather than an open standard
  • Battery doorbells need recharging, unlike a hardwired unit

The Xiaomi Smart Doorbell 3S solves the problem most Philippine installations actually have: no wiring at the door. Around ₱4,400 as of August 19, 2026.

What does the battery change?

Everything about the install. A 5200 mAh pack means you mount it with a screw and nothing else. No electrician, no chasing 8-24V wiring through a concrete wall, no waiting on a contractor. For a rented house or a door with no existing bell, that is the whole argument.

If you do run wiring later, it accepts 8-24V AC, so the decision is not permanent. It charges over Type-C in the meantime.

Will it survive the rainy season?

It is rated IP65, which covers dust and driving rain. On a Philippine doorway that takes horizontal rain for months and hard sun the rest of the year, a published IP rating is worth more than an extra feature, and several competing listings do not state one at all.

Night coverage runs on 940 nm infrared, and the lens is 180 degrees diagonal with 107 degrees of vertical view.

What is the trade-off?

The ecosystem. This lives in Mi Home, not an open standard, so it suits a household already running Xiaomi and adds friction to one that is not. And like any battery doorbell it eventually comes down for a charge, which a hardwired unit never does.

Is it sulit?

At around ₱4,400 as of August 19, 2026, it costs slightly more than the wired Tapo D130 and saves you an electrician, which for most people more than covers the difference. Against the older Xiaomi Doorbell 3 it is the clear buy: 2K instead of 1080p, and a weather rating.

Who should buy it

Buy this if there is no wiring at your door, especially if you already run Xiaomi devices. Skip it if you have wiring and would rather never charge anything, or if you want to stay out of a single vendor app.

Alternatives to consider

With wiring available, the TP-Link Tapo D130 gives a sharper 5MP sensor and a head-to-toe 4:3 view for less. If you want double the battery and the option of wiring, the Tapo D235 carries 10000 mAh.

Frequently Asked Questions

How long does the battery last?

Xiaomi rates it at 5200 mAh, which for most households means months rather than weeks between charges. It charges over Type-C, and you can hardwire it to 8-24V AC later if you ever run doorbell wiring.

Is it weatherproof enough for Philippine rain?

It carries an IP65 rating, which covers driving rain and dust on an exposed doorway. That is the sensible floor for a Philippine entrance, and several rivals here do not publish a rating at all.

How is it different from the Xiaomi Doorbell 3?

The 3S moves to a 2K sensor and adds the IP65 rating. The older Doorbell 3 is 1080p. The step up in resolution is the difference between seeing that someone is there and seeing who.

Do I have to use the Mi Home app?

Yes. It is tied to Mi Home rather than an open standard, which is fine if your home is already Xiaomi and a genuine consideration if it is not. Check that your other devices will sit alongside it.
