When the processor power, system specs and hardware feature set of Sony's debut entry into the handheld gaming market was announced back at E3 2003, the first question on everybody's mind was, "How long will this sucker last?" With multiple processors (including a 32-bit MIPS core running at a max of 333MHz), a moving disc medium for software, 802.11b WiFi connectivity, a giant 480x272 screen, USB and infrared ports, and Memory Stick support, the whole total package seems more apt to be plugged into your home theater system than tossed into a backpack for play at bus stops.
Most PSP user so far have been using the PSP for general use, mixing formats and trying different features. For exact results on what it is that drains the PSP's battery the most, testers have gone back over most of the system's features and put the handheld through intensive tests to drain its power in very specific ways. They designed unique circumstances to isolate specific features of the unit and see what it is that takes the most out of its runtime, as well as experimented with different features to find out how battery life might be maximized by players.
The test results are obvious. In hard performance test, the game is played on PSP for 3 hours and 32 minutes. In PSP WiFi test, PSP was battery dead after 2 hours and 46 minutes. In PSP MP3 test, it lasted for more than 10 hours, and in sleep mode, more than a day.
So we can draw our conclusion that WiFi connection drain power badly even more than games, and sleep mode hardly use power; in comparison, listen music can last quite a long time than most MP3 players. And how to extend PSP battery life according to this?
1.Use Wifi only necessarily required(in most times, turn it off)
2.Play less games, listen more music(if you prefer to)
3.Different games have different impact on battery life
4.Using sleep mode, off-screen as much as you can
5.Compared to the standard 1200mah battery, the old fat 1800mah battery is more advantageous
