Samsung Galaxy J3 2017: Rapid Battery Drainage After App Installations

Colleagues bought Samsung Galaxy J3 2017. I installed several applications that I had on an earlier phone. And I noticed that the battery drains very quickly. In the evening I charged 100% in the morning, the alarm clock woke me up and 42% of the battery was there. I did the test I charged it at 100% and after an hour without turning it on it was 89% What can be the reason for such a sharp drop? Applications that I use in the settings came out max 5%

The first and easiest thing is to replace it with another good battery and check if it also happens so. If so, it is possible that the charging system has a short circuit or is damaged on the board and thus it is such a fast charge decrease. There is also a software option that may have a bad battery saving effect, so change the soft. I would suggest you do the full format and on your phone what you have nothing to try or it discharges so quickly, and then the battery and if that's not the service.

You wrote the topic title S7, and in the post you write about J3 2017, so?

Yes thank you. The fault was the battery
