Fellow universal users who suffer from battery problems, i know this issue is reccuring and is in many threads and forums now. However i am sorry to increase the talk in another thread. I just thought i would share my peice of advice.
Attached is a pic of the universal battery and below is a little procedure that you might wanna try.
Lets say your universal battery is dying after 10 mins and you just had charged it overnight (meter says it died at 95% or whatever.. ) here is what you do.
1- take the battery out locate the pin provided in this pic attached. its the second pin from the top if you are holding the battery with the connector being to the upper right corner (just see the pic)
2- cover this pin with a thin peice of tape that you will leave temporarily. till the battery fully dies.
3- turn your universal on after placing the battery in it again
4- change the power settings in a way that leaves the universal on for all the time unless you manually turn it off.. so all the power savings are off.
5- let your battery drain all the way until it just turns the universal off.
6- take the battery out and remove the insulation from that pin
7- turn your universal on again and let it charge overnight or till the light turns green.
8- this fixed my universals' battery and now mine turns off at 5%

p.s. while the universal is running and the pin is insulated you will notice that the battery indicator that shows the percentage left doesn't work. (thats the whole point making the ppc blind and not being able to read how much is in the batter and take full advantage of whats in it as far as power goes, this will make the battery realize that it was drained more than usual and forces it to recalculate or recalibrate itself.
by the way you will also notice that the universal wont be able to get charged while that pin is insulated. so again my advice is fully charge your battery , take it out, insulate the pin then drain it all the way , take the insulation out and recharge until light is green.
please post if you had a successful result and hopefully for all who are suffering from this battery problem now they have one more hope.

This is what they call "Resetting" or "Formatting", nad while it's good for NiMH and neccesary for NiCd batteries, it can actually prove harmful to the LiION battery of the Universal, since it may over-deplete the battery.

Use with care, and only if you can't afford a new battery, since this might leave you without a battery!

Exclamation Deeply discharging of Lithium Batteries
People may remember the videos of burning Dells and Macs. Deeply discharging lithium cells puts them into a critical stage. You may loose a bit more than only the battery ...

well its not deeply discharging
i monitored mine and was playing games on my uni until it turned off once it did then i took the tape out and fully charged it.. then viola it worked fine. i dont see any risk plus yes there is in the lithium batteries a problem similar to the nicad research about it and verify.. anyway you dont have to follow, just saying this worked on 3 of my batteries.
Cheers

NiCd yes, but those are of a completely different architecture. There's something called the Memory effect there, which means that the battery retains the previous charge as the threshold for the next charge, meaning they can't be "topped up", because then only the "top-up" can be drained from the battery.

Lithium Ion batteries retain this memory effect too, that's true. But in them, this is nearly insignificant, meaning the can be topped up at any time, even at 99%, and the almost full charge can be drained. Almost, because there is a minimum threshold beneath which the internal mechanism changes and the battery becomes unusable.

That is why I recommend against deep-discharging the batteries. What I did once was ordered a battery, and noted that it came with a six-month warranty. Now I get a new battery on the warranty(free) every six months, regardless of the state of the old one. But usually by then it startsx to show signs of weakness...

Unfortunately, the Memory Effect in Li-Ion batteries can be made worse if the battery is of low quality and/or has impurities in it (due to manufacturing or age). This is why our original, top quality, batteries are dying (due to age) and the cheap ones we buy off ebay are pretty bad (low quality)

I second that. This may be a fix, but be careful!! As with anything in these forums, it caries its own risks.

Probably best just to buy a battery from a respectable shop\dealer and get a warranty with it...

hey guys ... i´ve tried it ...

i think it works, give it a try.

takes 4-6 hours to completely discharge, the i´ve loaded it one night long. today i´ve played long time with my colegues at work, used bluetooth several times, hat some calls... and now, after 10 hours without charging it has 45 % of charge.
at the moment i turned the brightnes to the maximum, with wifi, beam, phone and bluetooth on, to see at wich percent my universal will turn of.

i give you a notice if this happens.

cheers

Talking
now ... finaly it turns off at 19 % !
but ... without any warnings or notifications...

but before it always was shutting down at 40 %, now with shutdown value at 19% the battery is more useful as before.

maybe it could help someone.

cheers
