I ordered a battery of 3000 mAh ... and I received a battery of 2300mAh !! The image is so small that even by enlarging one can not read the battery power ... it senses the scam, full nose! Beware if you get a bigger Chinese battery BL-T9, you may need to change the cover of your Nexus 5 by a curved shell ... which originally is not the purpose of the maneuver. Sincerely.
