Sorry for another thread on this, but i've got a number of particular questions, and having read all the threads I can find, there's still a couple of things i'm not 100% on. 1. Would any micro USB 1A charger be safe to use with the phone? It's just I'd like to have a spare charger to take with me when at work/away on business, and having found that just USB from the PC is far to slow, I wanted to make sure it was ok? 2. Is regularly (daily) overnight charging ok? It's just that i've read t's not great to leave it on charge once it's full. That seems problematic to me if a overnight charge = 7 hours charging, but the phone only needs 3 hours to charge at least 90%. 3. I seem to get about 20-22 mins of heavy usage (wi-fi on, browsing/using apps) to 10% of the battery at the moment. The phone is only 1 week old though, am I likely to see an improvement, and if so what sort of one? cheers.
