Poco F5 and F5 Pro

Recommendation
Poco F5 > Poco F5 Pro > Redmi Note 12 PP > Pixel 6A

Reason for Pixel ranked low is because ownership of Pixel in Malaysia very troublesome compared to official markets where Pixel is sold in, since no warranty in Malaysia. And F5 Pro is lower than F5 because specs very similar and F5 Pro not worth spending extra money compared to F5.

If you are a Pixel fan, Pixel 6A is a good entry level phone to experience Pixel software magic for their camera, but not good for a daily driver in Malaysia.

Welp, that's sad, motherboard issues is common for all Xiaomi phones, whether it be Xiaomi, Poco and Redmi.

My family uses Xiaomi phones (Redmi, Poco, Xiaomi as well), and personally the best experience we had with Xiaomi was their T series. My sister's Mi 10T motherboard also broke after one year, but Xiaomi just upgraded her phone directly to a Xiaomi 11T since the phone was still under the 2 year warranty there was no stock of Mi 10T motherboard.

Another reason I also recommend the T series from Xiaomi, is because Xiaomi Malaysia offers 2 years warranty for all T series smartphones, compared to conventional 1 year warranty for Poco and Redmi phones. Also both Xiaomi 11T and 12T series are promised at least 3 major Android updates and 4 years of security updates.

Xiaomi 11T Pro should be avoided due to heating issues of the Snapdragon 888, and Xiaomi 12T Pro is kinda around RM2200-RM2500 price range, which is too expensive imo.

My recommendation for Xiaomi phones is as follows since your phone died recently.

1. Xiaomi 11T
2. Xiaomi 12T (go for this if you can find it under RM1500),
3. Xiaomi 12T Pro
4. Poco X5 Pro (though this one is only 1 year warranty, and only recommend if your budget is too tight)

Xiaomi 11T 256GB (RM1325 after discount) https://s.lazada.com.my/s.5rqi9

The upcoming Poco F5 could be cheaper than Xiaomi 11T, but a small comparison between F5 I did below for your reference.

Performance: F5 (Snapdragon 7+ Gen 2) better than 11T (Dimensity 1200)
Storage: Both are 256GB
Camera: F5 has inferior sensor with OIS, 11T has better sensor without OIS
Screen: Both are 120Hz FHD+ OLED
Build quality: 11T has Aluminium frame+Glass back > F5 is plastic frame+plastic back
Battery: Same 5000mAh with 67W charger included in box
Warranty: 11T (2 Year) > F5 (1 Year)
Price: F5 early bird pricing expected to be RM1499 for 8GB+256GB version, meanwhile Xiaomi 11T 8GB+256GB current lowest price that can be found is RM1325 for new set

Anyways, F5 pre-orders could take until next month June for shipping, if you need a phone right now, then buy the best phone that is ready stock
