Help HELP! fast charging duration

hagarmaher · Mar 6, 2016

I had my battery replaced month ago and as it was defective and they asked me to change the charger they tested.. I already had another one (original) of another note 4 that was lost so I used it instead at first the charging was amazing it was actually charging 50 or 60 % in 30 minutes.. but for the last few days I noticed it's taking longer.
It took now an hour and half to charge from 8% till 100% (including 15 minutes only to charge from 92% to 100%) is that normal?
How long does it take to fully charge your note 4 (fast charging)?
I'm afraid that other charger is also defective and I'm now ruining the new battery..
Update: after using the phone for only 15 minutes know it went down from 100% to 94% which I guess isn't normal..
Help please

I am going to suggest that you are miss using the battery.

8% is almost dead, and that is the "Blue Screen of Death" for a battery if you do that consistently.

Pun intended from "Microsoft Windows OS"

The battery manufacturers recommend to not draw them down below 40%. Lithium batteries will last "forever" if you keep them in the upper 2/3rds of their capacity.... I have a Qi wireless chargers installed in all of my phones, and Qi pads all over the house. If the phone is not being used, it is laying on a charger.... the battery has a monitoring circuit that tells the charger to cut back at 98% and from there it trickle charges to 100%, and then it only maintains a surface 100% charge. it will NOT over charge.

I have a 6 years old Samsung Galaxy S with the original OEM battery that is still very serviceable.... I just topped it off to 60% this morning.... for 'storage', it is best to maintain the battery at about 40%, do NOT try to keep it at 100%, that is almost as bad as letting it drain down to 0%

I'm not always doing this I usually charge it when it's around 30% .. I did that yesterday only to check the fast charging as I read here in the forums that the fast charging is only working when charging the first half (2% to 50%) but after that there is no difference between fast charging and regular charging so I was just examining this.. but it also took more than 30 minutes to charge the first half in my case..

I have not timed the charging at all, But, having noted that caveat, it seems to me that the 'fast charging' is not charging anywhere near as fast as it was a year ago. I imagine, that very much like most things, time itself is the problem. Very much like me...it's just getting old

And a very happy birthday to you AZ, I'm not far behind at 69, but you're only as old as who you feel! Phil

It might only be a coincidence, but I've noticed that as I get older the spring in my step becomes less springy. The truth is one feels one's age
