One of the biggest complains I read has been short battery life (about 2hours with 2500mAh batteries). There seems to be a work around, which is if you scratch off battery connectors a little bit, it would make it more efficient. The theory is that there is some sort of coating on those connectors that was blamed for the inefficiency.

Craig stated that the firmware shipping with the first units contain beta firmware, this inturn chews batteries. The next firmware is suppose to reduce power consumption quite considerably.

just the cheapest batteries you could get.. ^^ but hey, who really needs them? :p
 
Yup, I think I'll only ever be using high capacity rechargeables. I'll probably stick the supplied ones in a remote control or something.
 
I've been thinking about battery life a lot ever since the GP2X was announced.

I mean, it's like two BLU GP32's running overclocked to 200MHz each with light always on powered only by two AA batteries.

IIRC, the BLU was supposed to last around 4 hours on regular emulating duty, more or less (light on).

So how long can the batteries in the GP2X last, assuming you use it at full CPU speed (for SNES/Amiga emulation for example) and with light on?

Somehow I can't imagine how it's gonna last more than 1 hour or so. I mean, how would it work?
 
Well surely the electronics in the gp2x are more efficient as well as faster. I meen if you look at a 3ghz p4 chip, thats like hundreds of times faster than the proccessors from a few years ago in terms of speed but surely it doesn't increase in power consumtion quite as much.

How have you worked that one out? If the GP2X had two screens and the exaxt same processor, you'd be in a slightly better position for making cmparisons, but it doesn't have either of those things.

Well, it was a very rough comparison, I admit. I'm just worried because I already pre-ordered right in the beginning and every day some new worrying topic pops up. :-S

I hope the hardware really is that efficient.
 
Yeah, that's fair enough. I'm deliberately waiting to make my own opinion when I get the device next week though. A lot of people seem to be getting excited about problems that may or may not be real concerns, and deliberately or not, they're making people here get hysterical.
 
The problem with the current beta firmware on the units is, that is runs at full speed (2*200MHz and Backlight on), where it could easily run at 66MHz with 1 processor :)

That will be fixed in the near future :)
 
No Offence, but scratching at the battery terminals, silliest thing Ive heard in my life. I dont think GP would be stupid enough to coat the terminals in any kind of insulating matering. Even if it did it shouldnt make bugger all of a difference.

I was just reporting what I read, hoping it could be a useful tip just in case. Anyway, if you carefully scratch the battery connectors you will see white residue coming off, according to the report in gpain.com, and they claimed after this the battery life was improved from 2.5 hours to 6 hours. No matter how stupid it sounds, if it helps I'm all for it. :p

I appologize if I came accross rudely. Well if it has been reported white powder is coming off them that doesnt sound the best. Its true some oxides can have an effect, one just would not expect it on something manufactured new. I would guess it depends on the metal used at its tendancy to corrode. (form oxides).

I guess I'd be up for it too if it were true. Just a tip Id probably open up the thing and clip some jumpers directly to the board to test it rather than scratch away at it first.

You are right, we are on the .18 micron process, should save some power, but not if the clocks are going 200mhz full time

If you are running an emulator though you will need full 200 MHz speed. So for emulation the battery life will be exceedingly poor. Good thing I still have my GP32 BLU :)
