Addition of 2/9/2012 = battery is returned, the autonomy decreases too much too quickly!
________________________________________________________________
First, the seller first criticism: the product is supplied with instructions in English, so if you do not understand English too bad for you. It seems to me that to sell a product in France not accompanied by a leaflet in French is illegal ...
The battery, however, features two standards 9001 and 14001, which are intended to provide a communication pledge with the seller, but not in quality is surprisingly good! That may be why we see the seller replies, without knowing if the problem has been solved so far!
The battery is guaranteed for one year, so here it looks to go but if in a few months the battery is weakening faster than expected so I ask the refund (it is normal that the autonomy decreases slightly with time )
I'm on my third refill, I found that my mobile galaxy S2 alerted me to a low battery when it still had one hour of usage time.
The battery is inserted in place of the original one without any other change. The charging time will be extended by about 15%.
Important tips in FRENCH !!

You find two people with the same phone, same version of operating system (android, apple)! but one takes 2 days and the other barely a day !! WHY ???
I gathered here some tips on caring for your lithium-ion batteries therefore gain autonomy and to have an answer to WHY, I tried to simplify to the maximum to facilitate understanding.
So be aware that the lithium-ion batteries have an internal electronic circuit that stores the battery state of charge, in other words the estimated charging time and décharge.Ce circuit time accumulates the margin derreur and ended poorly estimate the time of charge / discharge, which reduces the battery life.
(Not to mention chemical degradation)
TIPS: First use of battery:
When you get the battery for the first time! it is imperative to put in charge until it covered 100% (manufacturers advice to leave in charge 12h without interruption).
After disconnecting and use his phone normally until it is empty and there is only one load between 15 and 20%.
NEVER let the battery reach 0% !! (See And never stop first load a new battery
Repeat the operation for 3 cycles.
For the impatient you can use your phone while it is charging
Day use:
Some rumors say that you should never load his phone (battery) only when it is completely empty to not lose charge cycles and shorten its life! This is completely FALSE with lithium-ion !!! it's true that for type Ni-Mh (Nickel Metal Hydride) since it is they have crudely call the memory effect. (This is not our subject)
So the right thing to do is to charge the battery before it reaches a threshold You should also know that small loads are beneficial to the battery (eg if the battery is at 70% you can charge it risk
And once a month to do a calibration as for the first use.

DO NOT HESITATE TO PLAYING THE 1 YEAR WARRANTY ON THIS ITEM DO YOU and TOTALLY REFUND, because the seller does not provide explanatory notes in French and that the product is expensive, technical failure is always possible because the seller provides a leaflet exposing the purchaser to make mistakes in the use of its battery !!
