With the increase in the size of the batteries, in this last generation of smartphones, the wall charger is back to being important: this is because to load more capacious batteries, it takes much longer.
How does it work in practice?
The capacity of the battery is measured in amperes, or rather milliamps (mAh), for example 3000 mAh.
The chargers also always indicated a measure of amperage, which for them indicates the amount of amperes that can be delivered to the battery in one hour, let’s say 3000 mAh again.
It mean that it takes one hour to charge that battery. If you have a 1 mAh charger and a 3 mAh battery it takes 3 hours!
That’s why the talking about the Quick Charge format, in its variants 2 and 3.
Chargers by these brands have a higher charge speed and allow you to quickly recharge the modern batteries.
And it’s not just a matter of amperage, but there are instructions controlled by the smartphone’s processor, which must be compatible with QC.
Using a non-original Quick Charge charger with your new smartphone can ruin the battery and risk burning it, as has happened to some iPhone X exemplary.
Moreover, it seems that the fast charge develops higher temperatures that deteriorate the battery considerably more than a “standard” amperage charger, on the long term. Also for this reason, the quick charge technology, over the 80% of charge, lower the amperage (the battery are more stressed when full).
What escapes the general public is that Sony has a small range of chargers, compatible with the XA2 series:
The standard charger is the UCH20 and is the one that is sold together with the phones. This is a 5V 1500mAh charger. (The amperage is actually already higher than the old 5V 1mAh standard …)
Then there is the UCH10 charger a few years ago, which is from 5V to 1800mAh and supports Qualcomm Quick Charge 2.0 standard (it was reviewed here ). You spot it thanks to the Quick charge logo on the left.
Finally there is the UCH12W which currently represents the top, supporting Quick charge 3. It is a charger that has various outputs 5V / 2700mA, but also 9V / 1800mA and 12V / 1350mA.
Sony states that “Give your smartphone a power boost. Charge for a few minutes and get hours of use. Comes with easy-plug USB Type-C ™ 1 and Micro-B cables. Source: Https://www.sonymobile.com/en/products/accessories/quick-charger-uch12w/specifications/
Obviously the prices vary and it’s up to you – Sailfish OS user – to assess if the fastest charging times are worth it!
