I also think it would be a good idea to have one place to consolidate info.
Yes! I would like to have a battery sub-forum!
Nah, not really needed.
It's simply counterproductive to charge full and drain full on every cycle from so many perspectives. First off, it stresses the battery and thereby reduces it's usable life by charging to 100% and deep discharging (15% or less) more often than necesary. I fact it can actually extend the battery's serviceable life considerably if we limit our use and charing to somewhere in the 50% to 75% of capacity range. Second, we all have unique usage patterns, due to varying lifestyles, expectations as to what we use our phones for, application installations, access to information services, streaming, access (or lack thereof) to charging sources during the day, proximity to cellular towers and WIFI hotspots, and the list goes on and on. For ANYONE to say that one battery and one charging profile fits all is just plain ludicrous.
So where do we go from here? I see all too many times, someone giving advice which they believe in their own minds is good and safe advice, usually gleaned from another who felt the same way when they conveyed this information, only to be giving the WRONG advice, and in many cases the worst possible advice ("drain the battery completely till it powers off at 0%", or "charge to 100%, then unplug, remove the battery and reinsert or power down and plug back in to 'pump' the battery", for instance). What they think they are doing is helping people to get the most from their batteries, but instead they are advising them to circumvent the protections put in place by the manufacturers of the batteries and phones designed to protect the batteries from such abuse, and to prevent the batteries (and the owner) from potential catastrophic damage.
Case in point, read and view the information below...
Counterfeit cell phone batteries (clone batteries)
In the search for low-cost battery replacements, consumers may inadvertently purchase clone cell phone batteries that do not include an approved protection circuit. Lithium-ion packs require a protection circuit to shut off the power source if the charger malfunctions and keep on charging, or if the pack is put under undue stress (electrical short). Overheating and 'venting with flame' can be the result of such strain. (See photos of an exploded cell phone with clone battery on charge.)

Cell phone manufacturers strongly advise customers to replace the battery with an approved brand. Failing to do so may void the warranty. Counterfeit cell phone batteries have become visible since the beginning of 2003 when the world was being flooded with cheap replacement batteries from Asia.
Cell phone manufacturers act out of genuine concern for safety rather than using scare tactics to persuade customers to buy their own accessories. They do not object to third party suppliers in offering batteries and chargers as long as the products are well built, safe and functioning. The buyer can often not distinguish between an original and a counterfeit battery because the label may appear bona fide.
Caution should also be exercised in purchasing counterfeit chargers. Some units do not terminate the battery correctly and rely on the battery's internal protection circuit to cut off the power when fully charged. Precise full-charge termination and a working protection circuit are needed for the safe use of the lithium-ion battery.
Folks, these companies aren't trying to make our user experience any worse by trying to profit from making us buy only "their" batteries and "their" chargers, they are trying to prevent us from making our user experience worse by using potentially inferior products. Frankly we have virtually NO WAY OF KNOWING if the battery or charger we use is the right match or if it could result in what you see above. Of course, I am not saying everyone should immediately start thinking of their phone as a block of C4, quite the contrary, but I am saying they need to respect the battery and charging circuits and use them according to tried and tested methods if they want to get the benefits they are wishing for, and don't want the potentially detremental effects they can bring.
I will stand on my soapbox as long as I have to in order to get the masses to start thinking properly with respect to these tiny powerhouses. They are far more powerful than you may realize. The battery in your phone is powerful enough to cause injury or worse from explosion, starting raging fires, or due to inhalation of volatile exhaust fumes if used improperly. Of course those are on the extreme end of the risk versus reward spectrum, but the risk is within reach of those who choose to take matters into their own hands and make poor decisions which are contrary to what the manufacturers specify.

yes, I applaud your effort here and commend your knowledge. I for one have heard much "authoritative" info on batteries. I have had several good and several counterfeit ones over the years. The latter all seem to come from Hong Kong, though some admittedly was not. How do you tell? I did Google one I bought and someone said if you tear off the cover it will reveal a smaller battery. Sure enough the 2300mah I thought I bought was only 1390 under the wrapper.One battery I bought that really lasted like theysaid was from Gorilla Gadgets. It was 3500 mah for $27 that really lasted. Gave me twice the juice for my Droid X2. My advice: cheap is cheap esp from HK.
this thread has got quite a few votes .. we will see what happens
