Yet Another Battery Problem...

[Coder_TimT]

Okay guys, here is what I'm experiencing. Got my GP2X a few days ago and everything was working great. Using 2500 mAh batteries(some brand called ULTRA Pro) and battery life was fine. Yesterday, that all changed.

It happened after I plugged it into a power adapter in my car. At first I had removed the batteries to make sure it was actually running off the adapter and plugged it in...that worked fine. Then after my testing I thought I would plug it in "for real" as I was leaving for work, so I plugged it in with the batteries in and the unit running...it immediately locked up with messed up graphics on the screen. So I quickly yanked the plug and restarted. It looked fine, so I thought nothing more of it.

Later at work, I was listening to some music and it only go through 3 or so songs before it died. Subsequently, I'm now getting next to no battery life. A fully charged set, shows half depleted on first boot(and that's a 10 second Art-U uboot, cramfs boot) and I can put on a movie for maybe 10 seconds and they're depleated.

Any thoughts or ideas? Was I supposed to know not to hook up a power adapter with batteries in? Or do you thing it's unrelated to that? It was an ebay purchase, so no recourse with a retailer...

Don't use the power adapter for a while.... maybe a few days, and keep on trying with batteries

This issue has been discussed 100 times already

Uhm the only issues I saw where not using the power supply for awhile fixed it were where the unit was not powering on at all. To me that seems to be that the unit thought the adapter was actually plugged in still and wouldn't use the batteries at all.

I'm seeing massive current drawn from the batteries. They are actually getting hot to the touch when in use. The only discussions I've seen with similar symptoms all ended with "I returned the unit for a new one". Just thought I'd put a slightly different scenario on the table and see if anyone had any ideas...

My batteries get hot from use too. Probably the reason they are using so much power and dying quickly is because the GP2X is taking the incorrect amount of voltage. Sometimes this problem is corrected in a few days by not using the AC adaptor...
