I hesitated to post this until I ran enough tests but I found an inexpensive source for a fast high quality charger in the from of the original PSP wall charger. It's spec'd at 5v 2amp, versus the .7amp of the original unit.
Not only did I check voltages and the like but also battery temperature and voltage using a HIDDEN option that exists on the phone. I am using the Extended Controls application to replace all the shortcuts and widgets on the main screen of the phone and it has the option to create shortcuts to hidden items. One of those under the "Settings" heading is called "Testing" and it gives you access to many informative items
I monitored the battery voltage, temperature and time to charge using the original and this modified charger. The time to charge was reduced drastically even while using 4g and full brightness screen. The battery voltage went up in a similar fashion between both chargers. The temperature seemed to be tied more to the activities on the phone rather than which charger was used.
I highly recommend a PSP charger with attached microusb cord. I disassembled one for fun and it is much higher quality than most other five volt wall warts. To help rid your fear, the usb spec says the device is supposed to determine the amount of power to be drawn so you could attach a 10amp supply to it and the phone would decide to use as much as it liked. Its the output voltage that is important. Some of the other random "name brand" 5 volt supplies had voltages as high as 6.2 volts!
Regarding that special test menu it shows the following.
Phone information : Shows all the network information including signal levels, lte or 1x, ip address, etc
Battery information : Shows many things including Battery scale (level), battery voltage (mine is showing 3920mv), and battery temperature
Battery usage : This shows a percentage for each item that used the battery with information from multiple sensors (much nicer than the normal screen)
Usage Statistics : Shows how many times and how long you've used each app
Wifi Information : This has three sub menus one of witch is Wifi status which shows the ssid, signal level, encryption type, channel, ip address and all sorts of useful stuff
The Extended Controls application is great because it allows you to comfortably put six application shortcuts on a line normally mean for four. I usually put five wide and it really decluttered the main screen of my phone. It also has a smaller footprint than many of the other apps.
