Réponse :
I think it would be good if telephones who never used up all their battery existed, because a normal telephone with 4000mAH holds approximately 5 or 6 hours in general (after it depends also of the telephones) and for me it is annoying, and apparently making chargers pollutes. The telephone that lasts the longest without a charger is the model Doogee S88 pro with 10000 mAH who holds about 20 hours.
