I’ve been having problems charging the battery of my Fairphone 2 since five days ago.
First day I plugged in my Fairphone to the AC with 40% of battery or so and after a few hours without using it I realised that the battery charge instead of increase had been decreasing faster than usual. I had to go and I couldn’t try to charge it again until the charge was completly empty, and that time it charges perfectly.
The next day I plugged in my Fairphone when it was at 15%. It happens the same, it didn’t charge and the battery decrease really fast. I tried with two different cables, I switched off the phone and I couldn’t turn it on again (I guess it was because the battery discharged completely). I spent almost an hour trying different things. When I plugged in it, the image of the inside of the Fairphone with the battery charging appears in the screen but just for a few seconds, after that the screens went black again, but with the red LED light. After an hour it suddenly started to charge ok again.
That night I plugged in it with a 48% of battery. It seems to be charging (the battery icon had the lightning symbol), but when I wake up in the morning my phone was off with no battery charge at all. I plugged in again and it charged a little bit (I had to go). At the afternoon I pluggen in again to AC and it doesn’t charged, so I tried connecting it to a laptop and it charged perfectly to 70% (I had to go before the charge was complete). At night in a friend’s house I plugged in again to AC and it charged to 100%.
Since then I haven’t been able to charge the phone with a charger with an out of 1000mA (AC and a solar charger), but it charges perfectly with lower current sources as a laptop or a external battery. When I plugged in to AC, I see the lighting in the battery icon and the red LED light but if I go to Settings -> Battery I see: 40% - Battery is not charging (or the percentage it has)
I don’t know if it could be a problem from the battery or from the software. I tried with three different cables, and some of then are the same I use to connect to the laptop. First day it happens before the last OS update, second day I update it and still happened.
My Fairphone 2 is one of the first bunch so it is exactly 1 year old.
Any suggestions? What should I do?
