前面的废话跳过，感兴趣的看看。
December 12, 2004 - The biggest question people seem to be having about the PSP concerns its battery life. And, now that we have the final system in our hands along with a bunch of games, we're sure you all want to know how long can you play games before the system dies?
Unfortunately, we can't answer that question for you exactly. Why? Because we haven't had time to sit down for four or five hours straight with a game and play until the system died.
The PSP is meant to be a multimedia device. You can play games on it, you can play music on it, you can play movies on it, along with god knows what else. Playing through Ridge Racers until the battery dies is probably not a good indication of how long the battery will last when you end up getting your PSP system and putting it to use for a variety of things.
However, you're still probably hoping for some way of grasping the battery's performance, and so we've created this little journal story. After opening up the PSP, we initially let the system run until the battery lost all its residual charge, and then charged it up completely to full charge. From that point on, we made notes of the usage of our system and the remaining battery life.
The PSP interface screen has an option which lists the remaining battery life both as a percentage and as a time. The percentage should be a reasonable measurement of the amount of charge left in the battery (at least while the system is new), but the remaining time is just an estimate made by the system based on your current operating environment, with the brightness of the screen seeming to play the biggest role. What we've done here is listed the remaining time setting while the screen was at max brightness and when it was at minimum brightness.
We'll be updating this story as we continue playing with our PSP throughout the coming days. Be sure and check back to see what kind of juice you'll be able to get from your system.
All times given below are American west coast times. We're actually running this test in Japan, so you may see some strange things where we refer to it being very bright during the middle of the night.
DECEMBER 12, 2004
12:54AM开机，电池满点
12:54AM: Turned System On
Following full recharge
12:54AM电池剩余100％ 满亮度预计剩余时间5小时49分 低亮度预计剩余时间7小时35分
12:54AM: Status Report
- Battery remaining: 100%
- Full brightness time remaining: 5:49
- Low brightness time remaining: 7:35
12:54AM开始玩游戏，山脊赛车、恶魔战士等，音量开到最大，屏幕（PS：这里不懂，不知道是指屏幕大小和亮度）调节到最小和最大之间（屏幕调到最小时画面看上去更好）
12:54AM: Played Games
Ridge Racers, Vampire Chronicles, etc., using system speaker set to full blast and screen alternating between minimum and maximum settings (videos look better when the screen is set to minimum)
1:54AM停止游戏
1:54AM: Stopped playing games
1:54AM电池剩余89％ 满亮度预计剩余时间4小时52分 低亮度预计剩余时间6小时21分
1:54AM: Status Report
- Battery remaining: 89%
- Full brightness time remaining: 4:52
- Low brightness time remaining: 6:21
1:54AM: Turned System Off关机
3:30AM: Turned System On又开机了
3:30AM: 使用USB和MP3功能。传了200M的MP3文件到PSP里，并且在去取另一部PSP的路上当做MP3用（写到我这里我想扁人，MD，我也想要）。接上了线控（应该没翻错吧）和耳机，听Prodigy, Utada Hikaru, Red Hot Chili Peppers and Nirvana的歌（懒得翻）。一路上频繁地跳转换歌，因为我觉得PSP的线控和耳机很糟糕（这可不是我说的）
3:30AM: USB and MP3
Transferred about 200 Megabytes of MP3 files to the PSP and used it as an MP3 player as I went to pick up another PSP unit. Had remote control and headphones attached to system. Listened to such artists as Prodigy, Utada Hikaru, Red Hot Chili Peppers and Nirvana, skipping tracks frequently as I determined that the PSP remote control and headphones suck.
4:30AM: Stopped MP3 use不听MP3了
4:30AM电池剩余76％ 满亮度预计剩余时间3小时43分 低亮度预计剩余时间4小时42分
（PS：MP3比想象中的要耗电哦，难道是频繁换歌的原因）
4:30AM: Status Report
- Battery remaining: 76%
- Full brightness time remaining: 3:43
- Low brightness time remaining: 4:42
4:30AM: Turned System On关机（^_^，IGN的文章也有BUG）
6:00AM: Turned System Off这次才是开机
6:00AM又开玩了，这次是玩高尔夫和装甲核心，开了全亮度
6:00AM: Played Games
Played Minna no Golf and Armored Core at full brightness.
7:00AM没意思（我不厚道地自己加的^_^）不玩了。眼一瞅发现电池头回掉到只剩两格了，于是决定看看还剩多少电
7:00AM: Stopped Playing Games
Noticed that remaining battery marker had fallen to two marks for the first time, so I wanted to check what the remaining battery was.
7:00AM电池剩余58％（两格） 满亮度预计剩余时间2小时35分 低亮度预计剩余时间3小时05分
7:00AM: Status Report
- Battery now at two marks
- Battery remaining: 58%
- Full brightness time remaining: 2:35
- Low brightness time remaining: 3:05
7:00AM接着玩高尔夫和装甲核心，为了录像而开到了低亮度
7:00AM: Played Games
Continued playing Minna no Golf and Armored Core (low brightness for making videos)
7:45AM意识到玩装甲核心并不是真的能操纵机甲，于是决定不玩了（汗……）
7:45AM: Stopped playing games
Realized that you don't actually control mechs in Armored Core, so decided to stop playing.
7:45AM电池剩余45％ 满亮度预计剩余时间1小时39分 低亮度预计剩余时间2小时07分
7:45AM: Status report
- Battery remaining: 45%
- Full brightness time remaining: 1:39
- Low brightness time remaining: 2:07
7:45AM: Turned System On.关机（还是有BUG）
9:15AM: Turned System Off忍不住又开机了
9:15AM为了确认到底能不能操纵机甲，又开始玩装甲核心了（为了录像调到低亮度）
9:15AM: Played Games
Played Armored Core just to make sure that you really don't control the mechs (low brightness for making videos)
9:30AM不玩了。再次确认在装甲核心里不能操纵机甲（……，拿着PSP干这种无聊的事，你们别拦着我，让我扁他……）
9:30AM: Stopped playing games
Realized, once again, that you don't actually control the mechs in Armored Core.
9:35AM电池剩余38％ 满亮度预计剩余时间1小时43分 低亮度预计剩余时间2小时19分
（这里我看不懂了，怎么电变少时间反而变长了）
嗯……似乎在玩了装甲核心后电变多了。也许当你玩不能直接控制游戏角色的游戏时，电会跑会电池里去（这儿应该是在调侃）
9:30AM: Status report
- Battery remaining: 38%
- Full brightness time remaining: 1:43
- Low brightness time remaining: 2:19
(hmm... the battery time went up after we played Armored Core more. Maybe playing games where you don't have direct control over in-game characters results in energy being given back to the battery).
9:30AM: Turned System Off.关机（BUG终于修正了）
6:00PM: Turned System On.开机～～～
6:00PM电池剩余34％ 满亮度预计剩余时间1小时35分 低亮度预计剩余时间1小时58分
（刚才电力变多是错觉？）
6:00PM: Status report
- Battery remaining: 34%
- Full brightness time remaining: 1:35
- Low brightness time remaining: 1:58
6:00PM在高亮度下玩Lumines（这什么游戏，照亮的意思），为了让这个游戏名副其实（这里我乱翻的，汗……）
6:00PM: Played Games
Played Lumines at high brightness (really bright outside) in order to try and 'get' game.
6:30PM发现电池头回掉到只剩一格了，于是不玩了，看看还剩多少电
6:30PM: Stopped Playing Games
Noticed that remaining battery marker had fallen to one mark for the first time, so I wanted to check what the remaining battery was.
6:30PM电池剩余25％（一格） 满亮度预计剩余时间1小时02分 低亮度预计剩余时间1小时24分
6:30PM: Status Report
- Battery now at one mark
- Battery remaining: 25%
- Full brightness time remaining: 1:02
- Low brightness time remaining: 1:24
6:30PM玩Lumines玩上瘾了（这什么游戏啊），于是继续玩（这次完全没发觉是在低亮度下玩的）
6:30PM: Played Games
Completed addicted to Lumines, so wanted to continue playing (this time, I accidentally played at low brightness without realizing it).
7:10PM电池剩余14％ 满亮度预计剩余时间30分钟 低亮度预计剩余时间40分钟
7:10PM: Status Report
- Battery remaining: 14%
- Full brightness time remaining: 0:30
- Low brightness time remaining: 0:40
7:10PM接这玩，Lumines实在太太太好玩了，这次我确定是在高亮度下玩的（这么好玩吗？到底什么游戏啊）
7:10PM: Played Games
Lumines is toooooooo much fun (this time, I made sure to play at high brightness).
7:20PM发现电力一格都没有了，而且电力条开始闪烁了，于是停止游戏查查剩余电力
7:20PM: Stopped Playing Games
Noticed that remaining battery marker had fallen to zero mark for the first time and power meter had started flashing, so I wanted to check what the remaining battery was.
7:20PM电池剩余10％ 满亮度预计剩余时间23分钟 低亮度预计剩余时间31分钟
7:20PM: Status Report
- Battery now at zero mark
- Power meter now flashing
- Battery remaining: 10%
- Full brightness time remaining: 0:23
- Low brightness time remaining: 0:31
7:20PM这Lumines真是好玩得没法说了，在高亮度下接着玩（管你什么游戏这么好玩，反正我玩不到……）
7:20PM: Played Games
Lumines is still toooooooo much fun (again, at high brightness).
7:45PM当我正在冲高分的时候电池挂了。不过没关系，PSP在电池用完时自动进入休眠状态，充满电后可以在上次没电的那个地方接着玩
7:45PM: Battery died
And I was right in the middle of a huge score in the Industrial skin on Lumines! It's okay, though, because the PSP goes into sleep mode when the battery dies, allowing you to continue play exactly where you left off, once you've gotten more power to your system.
7:45PM开始充电
7:45PM: Began recharge
后面的废话不翻了，感兴趣的自己看
So we've at last played our way through a full battery charge cycle. In case you don't feel like counting, the battery died after about four hours and fourty-five minutes of five different games and one hour of MP3 play. We didn't use the WiFi features of the system at all during this time.
Keep in mind that we avoided charging the system a number of times that we could've easily plugged it in (in particular, as we slept). Unless we plan on playing games for more than five hours in a row, the battery seems like it'll be okay to us. Of course, for long trips, we may find ourselves picking up a spare just in case (they're about $40 at retail).
We'll continue to track our battery use as we play around with more of the system's features over the coming days. From here on out, we're going to start charging whenever we feel like it, as this will be a better way to get an idea of how long the PSP will last when you're actually using it.
Stay tuned for updates in this space shortly.
没看懂虾米意思？
简单点就是说总共玩了5个小时50分钟吧?
就是玩游戏4小时45分加上听一小时MP3，没有开WIFI
那还是不错滴麻！！

哪可能？听MP3是最省电的，屏幕不用开，光驱不用转，就算加上听MP3的一小时，最多也只是5小时45分而已，你的5小时50分怎么得出的？？？

大哥，我故意写得随便一点就是为了缓和一下气氛，你咋这么计较捏
本人除了FC外再没有任何一台游戏主机，从来都是蹭机，不存在X或X饭一说
之所以用mj是因为主号注册1年有余从没发过贴，不敢拿出来丢人，今天起这个就是我主号啦，wahahaha
传说中的超级潜水员？？

12:54-1:54
3:30-4:30
6:00-7:00
7:00-7:45
9:15-9:35
6:00-6:30
6:30-7:45
不正好是5个小时50分钟吗?
而且根据他用电比例来看,挺MP3的1小时耗电并不比游戏省(用了13%),或者说游戏的耗电量并不高?
所以我说共玩了5小时50分钟哪里有问题?
7:45AM意识到玩装甲核心并不是真的能操纵机甲，于是决定不玩了
-----------------------------------------------------------
这句话什么意思？难道说游戏方式和以前不一样了？
没错，这款＂庄稼核心＂就是骗钱的．
昏。
先是三国无双，再是装甲核心，psp上还有什么游戏可玩的？
PSP的游戏估计难有新血,倒是NDS的游戏更值得期待.
Lumines是前sega制作人水口哲也的音乐游戏吧？
nds上也有类似作品~~
本来一早就知道PSP电池不怎么 以后肯定会改进的```
要买的也是 周渝打黄盖 ---- 一个愿打一个愿挨
管那么多干什么
能完5小时就不错了```多买个电池换到打就行了嘛
传说中的超级潜水员？？
看我的注册日和发贴数，跟他比起来咋样？
12:54-1:54
3:30-4:30
6:00-7:00
7:00-7:45
9:15-9:35
6:00-6:30
6:30-7:45
不正好是5个小时50分钟吗?
而且根据他用电比例来看,挺MP3的1小时耗电并不比游戏省(用了13%),或者说游戏的耗电量并不高?
所以我说共玩了5小时50分钟哪里有问题?
不好意思哦，我不知道原来听MP3耗电和玩游戏一样多的啊？奇怪，听MP3时屏幕不用开，又不用放UMD，就是光驱也不转动，这样也和玩游戏耗电一样？不敢相信！！
不厚道的说一句PSP的实际使用时间和NDS的差不了多少，而且开最低亮度就够了，这样又能省一点咯~~太好了
先不管官方的时间是多少，请各位想想4个小时的概念是什么？
早上7点到11点 或者 下午1点到5点 或者 晚上6点到午夜……
我想没有人玩PSP会玩一整天的吧（新买的除外），备上两块电池轮番上阵，足矣……
所以，游戏时间不应该成为PSP饱受苛责的理由……
