Battery for the Samsung Galaxy S4 - a fake?

As more and more quickly my old battery of my Galaxy S4 was empty and even became more and more hot, although I thereby no power-hungry applications had running, a new was needed. Because in the beginning it was not the case!

First thing first: The battery arrived quickly and put it in the original packaging, as it should be!

When battery replacement should turn off the mobile phone and charge the battery first when switched off before taking action. Batteries are in fact only partially charged to avoid during storage and transportation deep discharges, which destroy the battery. And if you "fresh", partially charged batteries does the same first empty, you promote so only wear. So Always recharge before using the battery! ;) And this is true for each battery unless it has been fully charged before the manufacturer at the factory (if accordingly indicated on the package). This is to my knowledge only with the cylindrical cells (AAA, AA, ... - these parts I mean) the case.

Back to Topic: Until such a battery reaches full capacity, it needs a few charging cycles (5-10 cycles). In my now has a cycle behind. I think he holds already longer than the old battery. I'll update the review once when the battery has reached its full Kapaziät and again after about six months and describe how the "newcomer" does so.

Thus, the battery has reached its full capacity. These 6 recharges were needed - very good! The cell phone I do not have terminals every day to the charger, despite intensive use now. Also there are no problems with the heat DEVELOPMENT. During use and charging (also to occasional gambling belongs) of the battery is very cool compared to the old. Also charging seems to go faster.

Meanwhile, the battery is quickly empty again. Too bad! In my case, it's not so bad, because I have an external battery with 14000 mAh capacity, but it bothers me a little. After all, he is unlike the Erstakku not hot, but the charging time - even on the original charger - has increased again.

The battery is always empty faster. He did not even holding by half a day. It's annoying but pretty! Have decided to downgrade my initial review from 5 to 2 stars (was actually overdue!). Although I as mentioned in the last update, possess an external battery, there is no fun anymore, that the mobile phone almost exclusively depends on the cable ...

Through a review seemed only right in the sense that it is, probably could be a forgery in the battery, which I received at that time. Thanks to "shopper". Here is the link that has been posted with the comment: [...] the features described there and the behavior (! My copy went limp after 3 months) is my battery very close. I had already fear that it could be a fake, but without concrete evidence, I did not mention it. Nowadays you have to watch what you say. My battery I had by the seller "gc-mobile".

Well, this battery I replace this: mumbi Battery Samsung Galaxy S4 replacement battery 2900mAh (without NFC). Has 1.5 months in use and shows no weaknesses.
