After an initial order of an empty battery with another provider, I came here for a new battery for my Galaxy Nexus. The battery is actually sold in blister but confectionable by everyman. in other words, not in accordance with Samsung standard, ie Round Stickers "original Samsung" and easily recognizable tamperproof tab as more complex than a vulgar piece of white or transparent scotch in my case (not a something that we can do it yourself). And indeed, the battery has the autonomy of a new battery !! even a supplier to avoid ... With the old battery, just before the change against it, I was one working day an average of autonomy, with it, I have a day and a half (still working hours) it's ugly ... especially when we know that the old battery to 3 years ... and for stronger electricity is still a 1750mAh !!
