when E2\E6 is starting to "cry" about "dead" battery turn off every thing,just let rokr die a "natural death" with out any stress(no cpu overclock,no music,no java,nothing at all)
try this for 1-4 times and E2\E6 PDS should "relearn"
but this is only on theory,I did not tested,coz I use my E2 extremly,so I use my 2 battaryes a day
hmm... Li-ion batteries don't have memory effect... check this out:
Most lithium-ion batteries use a fast charge to charge your device to 80% battery capacity, then switch to trickle charging. That’s about two hours of charge time to power a device to 80% capacity, then another two hours to fully charge it, if you are not using the iPod while charging. You can charge all lithium-ion batteries a large but finite number of times, as defined by charge cycle.
A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean a single charge. For instance, you could listen to music for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle. Each time you complete a charge cycle, it diminishes battery capacity slightly, but you can put cellphones, notebook, and other batteries through many charge cycles before they will only hold 80% of original battery capacity. As with other rechargeable batteries, you may eventually need to replace your battery :'(
I need to go back to tri-band BP. My Stock Firmware came with 850, 1900 and 1800 bands. My operator doesn't offer EDGE so I don't need it... I just need to reset some seems to get this configuration back. Can somebody help me?
