Sony to PSP Coders: Battery Life Your Problem

AssaultOnBattery writes "The fine folks over at GamesIndustry.biz are reporting that Sony has found a unique solution to the problem of battery life on the PSP - making their game developers solve it for them. According to the story, Sony is going to give devs a battery emulator which will tell them if their game is within acceptable power consumption limits."

    If you can't access the disc often, that means only one thing. You have to load all the info off the disc into ram beforehand. That means, LOAD TIMES. Want to whip out your PSP in class for a quick game before the teacher gets there? Sorry, gotta wait a minute for it to load. Oh shit, times up! Not good for the PSP. Which was already looking bad with its much higher price tag.

      The PSP's UMD has an 11 Mbps transfer rate and the unit has 32MB. It can't take more than about 30 seconds to fill main memory. However, there's no reason you can't load enough to begin doing something (for instance, showing the countdown in a racing game) and stream the rest of it until memory is filled. It will require some clever programming, but I don't want games made by stupid people anyway. I can't imagine that no one is doing this now, anyway.

    The PSP is a very complex machine(with a motor for the cd reader), and thus battery life will vary greatly depending on what you are doing(versus say a gameboy were battery life is easier to determine in general rather than per game) You want to load a lot of textures? That is going to kill your battery life. You want to have a lot of music? Going to kill battery life. A game such as quake will obviously take more battery power than puyo puyo pop. Sony did itself and it's devs a favor by providing this little kit.

      There's just absolutely nothing that Sony can do about this.

      Actually, you're wrong here. They could put more RAM into the PSP. They could put out devlopment kits that allow developers to try and use Sony Memory sticks as RAM or at least cache. They could spend a little extra on the drive for one with a lesser seek time (thus not requiring the disk to spin as much or the laser to move as much), like Nintendo did for the GameCube's speedy little disk drive. They could use a more powerful battery in the unit.

      Or, they could try and not foot the blame for their own inability to come up with an estimate for battery life off onto the developers by making something that "just works," or allow themselves to actually have something they can be balmed for because they tried to cut corners on manufacturing prices to try and maximize profit off of the PSP.

      This is just Sony's way of trying to say it isn't their fault if the PSP dies 10 minutes into a game; it has to be the fault of developers who didn't follow their guidelines for battery estimates that Sony can't even give yet.

    This seems like the final nail in the coffin for the PSP. After all, what good is amazing, state-of-the-art hardware, if the developers avoid pushing it to its full potential for fear of draining the battery?

    Remember the Game Gear? It was lightyears ahead of the original Game Boy. Color, backlit screen, processing power... The bastard took 6 AA batteries and lasted about 4 hours. (There was a trick where you could add a 7th AA to the section of the power supply that handled the backlight and get about 7 hours out of it, but that was little-known and difficult) It sucked batteries like a hoover, while the less powerful Game Boy lasted forever with it's ugly little brown-scale screen ;^)

    Furthermore, what about load times? The PSP uses discs right? Power consumption concerns will put the kaibosh on streaming from the media, which means LOAD TIMES! That might be well and good on a console, but on a portable? These systems are supposed to be quick-on, quick-off, quick game before class or before the subway gets here.

    It won't quite be an N-gage, but the PSP will definitly be "Game Gear 2"

    Well the Nintendo fan-boy in me would like to predict doom and gloom for Sony's PSP. However, I think I'm missing the point of why this article is as negative about it as it is. It's not like Sony can put an optical drive in this thing and magically make it work forever on batteries. If Sony's trying to say "look, don't piss off our customers" I say more power to them.

      First, I don't think you know what 'innovative' means. Optical media in a portable is not innovative. (In a gaming portable, maybe, but you say yourself that the purpose of the device has no bearing.) The audio options are not innovative, they're a waste. It's like putting a retractable corkscrew on the system. Neither is the arctitecture, of either system. Incidentally, the only innovative thing about these systems are the screens. You think dual screens are a gimmick, which may be true if you fail to consider that one is a touchscreen. And PSP's is simply massive enough and pretty enough to cross the innovation line, IMO, simply because it is treated as the system's main feature.

      My biggest complaint about your logic is that you say more mario games are not innovative. If that's necessarily true, than you could take your favorite game, insert some classic character, and it's no longer any good. Not innovative, either, if it even was in the first place. Mario 64 was quite innovative at the time, and had enough of an influence that it can even be hard to remember that these days. Even the more recent installments, Sunshine and Luigi's Mansion, were really quite innovative, though I'm not personally a fan of Mansion. Also, look at the Super Smash Bros. games. Not a single new character in either of them, but to this day, they're still the only two games of the kind.

      Also, I don't really see the games on PSP looking to be all new. The most hyped one is the Gran Turismo game, which is something I've certainly seen before. Guess it must not be any good then, huh?

      At the same time that this is my biggest complaint with your logic, it is also the single most important point. The games are what matter!

  6. Geez ... by SuperRob · · Score: 3, Insightful

    If Sony is going to put the battery life problem off on Developers, then I think that having a battery life rating on the box, as accurate as possible, should be a requirement on each game. Maybe gamers only buying games that will give them a decent play experience will convince Sony that battery life is a HARDWARE problem, not a SOFTWARE problem.

    This is why no one has wanted to use an optical disc in a handheld until now. Funny how much a simple spindle can drain a battery.

    There are a couple of posters who have said this is a silly idea or its should be up to Sony to ensure enough battery life is available for its gear.

    Well I think that you havent really got the gist of what Sony are saying. Sony can make the battery for the PSP as good as is possible (within the confines of cost and technology) for the PSP but if the thing is running say "Tetris" is going to use a hell of a lot less power than if it is running "Doom III". This thing aint a gameboy its basically a PS2 running off a lithium battery-powering a pretty damn big screen and some pretty powerful hardware.... just how long do you expect the battery to last on this thing?

    Encouraging game developers to be careful about use of processing power and other parts of the hardware (eg optical drive motors/screen's/speakers) etc. Makes sense!

    The more powerful these handhelds/portables get the more conservative use of hardware and resources is going to be an issue.

    EG: imaging a game that streams shed loads of fmv off the optical drive... maybe there is a better way of acheiving this than having that drive constantly spinning. Howabout the use of audio etc ? having it constantly playing through the game? even on the title screens etc. There are lots and lots of legitimate reasons for Sony to encourage efficient use of hardware- I applaud them for that. It is Sony's job to ensure that the games that come out for the PSP are every bit as well engineered as the console itself. Cut them some slack 'cus they are only doing what is neccesary...

      I'd expect Sony to realise that putting moving parts (spindle/lens) into a handheld is going to cripple battery life and result in a system that will only play mediocre games if you want a decent battery life. The point is it's *too much* like a PS2 running off batteries... it seems more like a bodge than an innovation.

  13. Re:Horrible answer... by DarkZero · · Score: 4, Insightful

    To me, it seems like a horrible answer to a (what should be) simple problem. Developers should be concerned with making a good game, not how much battery life their game will have. I'm sure this will eliminate or seriously affect entire genres. When building a portable, you would think that one of the first things you would focus on is battery life. Most companies hold off on releasing a product until it gets acceptable battery life.

    I think you're misunderstanding the issue, here. The problem isn't that the hardware takes up a lot of power. The problem is that with an optical drive, the software developers have control over how much power their game takes up, not the hardware developer. One software developer can create a very efficiently coded game that very rarely spins the optical drive, while another could create a very inefficient, poorly coded game that spins the optical drive almost constantly. So whereas one game from one company could drain the battery in ten, another game from another company could drain it in just six.

    And the worst part is that when Spongebob Squarepants: The Jackass Licensed Game Developer's Adventure drains the battery in six hours, no one will care that other, more professional developers like Capcom and Square are getting four more hours of battery life out of their games, or that the problem is obviously the Jackass Licensed Game Developer's fault. They'll just blame Sony, because they've never had an optical drive in a handheld before and will assume that any power inefficiency is the hardware developer's fault, just like it was with Sega and the Game Gear.

  14. What's a handheld for, then? by KDR_11k · · Score: 5, Insightful

    That would be a desaster. Handhelds see much usage during short wait times, wait for the bus, wait until your train arrives, wait in line, etc. If the shortest you could play the PSP for would be, say, 30 minutes, you could only use the system during very long breaks (like lunch break). Those rarely occur naturally and you'd be limited to long trips and time you take yourself for the PSP. Most of that allocated time is in your free time, anyway and most likely those parts of your free time you'd spend with gaming are spent at home. And at home there's no need for a handheld. And even less need for a proprietary movie format that only plays on the miniature screen.

    So, again, this comes down to another way for Sony to make more money. My point is, they made sacrifices to the core system in order to make money, either through selling you things that are not games or by cutting the costs of the game media.

    For a home system, discs may be fine. While on the road, battery life and loading time are two of the primary concerns, two that aren't addressed by Sony.
