[EVO Shift 4G General] herbthehammer:
I was just about ready to throw in the towel and say the phone was defective, but then things started happening. I will fill you in on what I have done in the meantime. Okay so the flipped over evo battery kinda works but not completely. It will charge but not to 100% and green light. To test this, I took the evo battery out of the shift. It didn't seem to want to go more than 98 or 99%. I put the battery into the evo and after a few minutes the light went green. This was initially off. Then I booted the evo and let it go to sleep. After it booted the light went orange then green after a few minutes. Okay so the evo battery is capable of going to 100%. These charging tests were done with a different charger.

I forgot to tell you, I let the evo battery charge while I was at work and the phone was off. So the battery was charging roughly twenty hours and still no green light. I suspect that even though the positive and negative terminals aligned with the correct tabs on the shift, the center two contacts must be different internally than the shift battery. I speculate that those center tabs are for the battery and phone to communicate to each other during it's charging state. I am guessing that the battery tells the phone it is fully charged and to go trickle charge and perhaps the evo battery wasn't communicating to the phone or the phone didn't know when to say it is done charging. The battery never got hot either.

The shift was rooted, running mikshift 1.1 and the latest clockworkmod recovery. Here is where I suspect that there still might be charging bugs with that setup. I used the pcxx.zip file that when booting into the bootloader, would flash the phone back to stock everything. After trying this and assuming that the phone was back to stock, I kept going with my what the hell is going on with this phone battery charging test. A note about the flipped evo battery. Yes it will work in a pinch but it won't charge properly. Luck has it that the notches in the battery and phone allow it to work in a shift. Only thing is, the shift battery won't work in the evo. The tabs are on the wrong side and the phone's tabs won't allow the contacts on the battery to meet up with the phone's terminals.

Okay, where was I? Trying different chargers wouldn't make the shift green light full charge. I tried the same chargers on the evo with it's original battery in and it would green light after a few minutes on or off. There wasn't anything wrong with the chargers. Oh and another note, while using the battery monitor widget, I noticed that both phones wouldn't pull more than a little over three hundred milliamps of power from the charger to the battery. Interesting to know how much it really pulls from the charger.

Anywho, I tried something different for my process of elimination testing. I actually ruu flashed the shift back to factory and guess what happened..... The battery and phone were charging both on and off all the way to green full charge at 100%! I think I'm getting somewhere with this! All my luck, either it is a known bug somewhere in the forum in a place I haven't stumbled across or I'm the only one that this is happening to. It doesn't really matter I guess.

My conclusion, which isn't scientific by any stretch of the imagination, is that the phone isn't truely back to factory unless you ruu it. The pcxximg.zip doesn't put everything back to stock. I haven't narrowed it down to what is causing this behavior. I don't think it is root. It could be cwm recovery or the rom or both. I didn't try the stock rooted zip either. I suppose I could go further with this investigation but I am too lazy to now. I might root it again and just leave things stock rooted. I might activate this phone in the morning and run it all day tomorrow and see how it acts. I will have to charge it a few times during the day to keep the levels up when I really use the phone heavily. I've written enough for now. Does anyone have anything to ask or add to this topic?
