but isn't heat no good for battery?
Say if I don't mind taking long time to recharge so I choose to use lower output chargers(such as samsung's charger), it won't do any harm right? just longer charging times which I prefer over heating up my phone and feeling worried.
All power conversion will result heat. Why? Bcoz nothing convert with 100% efficiency. Simple way of saying.. Z input = xx stored + yy heat. So charging or even using ur handset will produce heat no matter what.
Yes heat is no gud to battery just as heat no gud to us coz make us sweat and smelly. Kampong girls not so much bothered with heat but metro sexy girls sure 'cair makeup tebal2'. The fact is we cant escape from heat. Just how much is is damaging. Fake batt is just like thick makeup girl.. beauty sure short live.
Back to either usb or pwr charging is better? Well, I think pwr charging is better bcoz not only faster but also less voltage fluctuation during charging. If u use less capable charger bcoz u want slow charge then the charger probably would chock when ur handphone trying suck more juice then its capable of giving. This would result in spikes and reduce effeciency producing heat although bit by bit during process.
Charging goes to tickle charging mode after certain % to prevent overcharging that can damage batt. Its ur hand phone which decides how to suck.. Ha.ha..
Sori my ramblings. Cannot sleep coz heat. Now AirCond on ady.. so gud nite.
