its definately the phone, as the desktop charger is also usually useless. when plugged in (to either the mains or desktop charger) :-

- the phones green "charging" bar may move up and down, but its usually not REALLY charging

- when the screen goes off automatically as usual when not in use, the orange charging light may go on and off, indicating a charge, but its usually not really charging.. as an example, even though it "knows" I have connected the mains plug to it, sometimes its SWITCHED OFF at the mains! lol.. so its really just wasting more power. when connected to the pc, after a few mins I can switch the phone on again, no increase/difference to the amount of power left

- sometimes (when the screen is on) literally after around 3 or 4 seconds of the green bar moving, it will tell me to "disconnect the charger" to avoid wasting power... so even with little or almost no power, the phone THINKS its fully charged (despite the battery bar being empty)...?!?

- at other times when I connect the mains plug, after a few seconds it will literally say "stopped charging" for no reason, and the green charge bar stops moving!

- when on the occasion that I cant get the phone to charge AT ALL, and its ran out of power completely, I am at a loss, unless I wait a long time inserting the cable 100x times until it starts really charging

..........I had not installed anything new when all this started happening, so its not likely to be a "new installation" of any particular software thats caused the problem. I thought it might be my charger leads (or the phones charger connectors), as sometimes the orange light flickered on/off quickly whilst on, perhaps indicating a poor signal, but when it decides to work out of the blue, its ok again.. the problems of not being able to charge seems to occur most often for me when the power is VERY low on the mobile, although perhaps it just seems that way, as thats when you would panic most trying to get it to work Im pretty sure moving the keyboard in or out whilst charging makes no difference-waiting for the next update (2 yrs time, if the phone is still being updated by then) or forcing a downgrade/reinstalling the old firmware might be the best bet, although Im not sure I want to chance ruining the phone for good, lol.. it doesnt charge, but when it is charged, it works. just! lol
