Hi, I have a Samsung Galaxy FE. Its about 3 months old now and I have had no real issues with it. The battery life day to day isnt the greatest but its fine.
The last two nights I have had it on charge though, I plug it in and from say 12% battery itll say it will take 1.5hrs to charge to full. Then within a minute it suddenly says itll take 4.58hrs! So I just left it on charge and then 8 hours later I wake up and look to find its still only on 59%!
It charges quickly on 'fast charge' to 100%. So its not like I cant charge it. But I figure to get more life long term out of the battery its better to slow charge and I cant understand why it would fast charge, and until 2 days ago slow charge in a couple of hours max....to not slow charging in less than 8 hours!
