Conquer will drain battery beyond use (read before buying)
Everytime your conquer runs out of battery, there is a certain chance it will not have enough battery to boot again.
Unless you have a SPARE battery, (I am fortunate enough to have two conquers, so I can swatch batteries at will) the phone will simply be 'dead'
It will not charge, or even boot, while plugged into either a computer USB outlet, or the stock charger.
My phone died due to the battery dying. Nothing new, but when I plugged it in to charge, it would not turn on like normal (automatically, into charging mode). When I pressed power, nothing. But, when I switched it out with ANOTHER conquer 4g battery of identical make it would power into charging mode like normal. Hmm.
What would the second conquer do, the one with the battery that suddenly refused to work properly? Well. The second phone simply didn't work, either.
The battery was so drained, it would not even boot to charge. To make things clear, the 'first' battery, the one that when in use prevented the phone from even entering into charge mode stopped working. If that battery was in either phone, the phone it was in would not work.
Nothing unusual happened, there were no problems beforehand. The battery simply died due to a long period of no charging, and when I tried to charge it for a few hours it resulted in a whole lot of nothing for a few hours.
What the hell? You can't even turn the phone on when it's plugged into an outlet? I can switch the battery and suddenly the phone will start to charge and turn on?
Bull. I probably shouldn't be as mad as I am, seeing as I can still use my phone, but if I did not happen to be in the position of having two samsung 4g conquers, I would be SCREWED.
This battery did not die in any unusual way, it has endured only a few weeks of use, and it died because of normal use (idling and talk-time, nothing more).
Please, do not consider saving some cash to get this droid. Get something else that won't quit on you and require you to buy a new battery or go phone-less while your carrier replaces the battery.
If what I'm saying isn't clear
The battery died while idling, and when plugged back into a charger, it would NOT turn on, even after several hours. However, when I put a different battery in (that was also 'dead') the phone had no qualms about doing what it was supposed to and going into charge mode, which let me boot it into regular mode.
Both phones were rooted, both died while idling. However, if you had battery A in either phone, it would not boot, but battery B would.
The battery that is now 'non functional' never had any quirks, and I do not believe it to be malfunctioning. I think it is more likely the phone simply requires the battery to have at least a LITTLE juice in it to function, even if it is plugged into a functional power source.
