this not seems to be a problem you can solve with any software or charger or reset whatever. Lithium ion batteries, which sold in these small protector are for discharge rate ~1-2 amp about, not too high. That means the battery internal resistance is higher than a 30 A drain battery for example (I usually use a lot of type of Li-ION for vaping) The only thing which actually HEAT the battery itself, that is Draining faster than it shuold be, it means somewhere you have a short circuit, so the battery discharge at max rate continuesly. Do not worry all small lio-ion box has internal features for safety and cell balancing, but anyway, once the battery get heaten it means damage to itself, if you keep in this environment all of ur battery will be damaged or eventually dead at the end of the tries. What you experience that the circuit coming from the adapter is fine, phone works, so it seems you have some contact problem between the battery and the phone. Eventually I read "self repaired" isn't it possible that somewhere you caused a small circuit with connector tin?

Once more if it would be anything related to hardware or software, the phone would heat and not the battery. At maximum normal discharge rate a 100% battery should stand for 2-3 hours depending on the overlocking, if you get a lot less amount of time that means you introduced a new consumer circuit, as I don't thing you put some additional hardware I assume the new power consumer is a short circuit...


If the battery getting hot that's is always a bad sign, especially during discharging, battery should only get a bit warm during the charge.... I am using li-ion cells for heating 150-200 watts on 6 VOLT that means about 25-40 AMPER and batteries are not even warm, because those cells designed for it, however I tried to vape with a regular low drain ultrafire cell in the past it was venting and dead for 10 AMP, in the phones usually use longer but "weaker" batteries as the drain is relatively low. I am really supprised that N900 hundred without cellular interface can stand more than a week, even I use it sometimes, brilliant design compared to the current smart phones which actually must be charged each MAX 3 days not matter if they are being used or not.

I still won't recommend anyone to play with circuits on small areas, u need micro soldering rod and good quality zoom lens or elekronic microscope , good hand and a lot of patience, it is always a better idea to give it to the specialist for a fix rather than make your life harder

Now you are risking your batteries not only your phone, Li-Ion cells are suffering damage over 40 celsius damage means shorter life span in general degraded capacity and at the end the internal unit will report battery is dead, and will give you no power at all!
