2 SIMs. Get approx 4 to 4.5hrs SOT. Normally Whatsapp, Telegram, Carousell and browsing.


BTW for all those asking about cables, chargers, charging speeds etc, there's this app called Galaxy Charging Current by Abmantis since the Note 2 days which gives a good reading of the charging incoming current and you can use this to narrow down faulty cables or chargers.

This app supports only Samsung phones and I've been using it since 2012.

For non-Samsung phones there's another app called Ampere.

There was a guy who did a teardown of one of these units, quality is poor and charging speeds are just normal Qi speeds.
