I had created a new topic for my problem. Since this seems relevant, I am sharing it here as well.
My Fairphone (FP1) was working fine all along. I was even able to update to the new OS update (Cherry) with no problems whatsoever.
But, yesterday (August 24th, Sunday), I faced a problem with my battery and I still havenāt been able to fix it. This is what happened:
I had left my charger at home and was staying over at a friendās place since Saturday evening. I had last charged my phone on Saturday afternoon (say till 4 PM). I used the phone for some photos, messaging, calling. I was also using the data connection for quite a few hours. By Sunday afternoon (2 PM), the battery had come to 17%. This is normal behaviour.
Since I needed my phone to pick up tickets at movie hall, I switched it off to conserve battery. At 4 PM, when I tried switching on the phone, only the blue screen was coming up - no FAIRPHONE letters. I tried holding the Power button, it switched off. I tried this a couple of times, same result. This was symptom #1.
Then I waited at the blank blue screen itself and after a few minutes, the FAIRPHONE letters came, and the phone started. The battery was at 11%. This was symptom #2.
I used the phone to pick up the tickets, sat in the hall, and when I looked at my phone after 15 minutes or so - it was off! Symptom #3. I assumed that the batter was still very low, so decided to charge it once I got back home.
I got home in the night, charged it for 25 minutes or so (I donāt ever leave the phone charging through the night). It was at 30% when I went to sleep. In the morning, the alarm didnāt ring, I checked the phone and itās drained completely again! Symptom #4.
I charged my phone while getting ready and as I left my home to go to office, the battery was at 52%. After cycling for 45 minutes, I stopped at a traffic light, pulled up my phone - battery was at 44%. Symptom #5.
I switched off the phone, and am charging it right now.
NOTE: Since Sunday 2 PM, no extra service was switched on in my phone. No Data, no WiFi, no Bluetooth, nothing.
Why is this happening? I would really be glad if someone can walk me through fixing this.
UPDATE 1:
The phone was being charged and was at 70%. I switched off the charger, took out the battery, put it back in again and re-connected the charger. The phone takes almost 2 minutes to start charging. Until then only the battery symbol with the lightning comes. The red LED light comes after 2-3 minutes. I donāt know if this is part of the same problem, but sharing it.
UPDATE 2:
The LED light shows green now, though the charge is at 90% only. Is that expected or symptomatic?
UPDATE 3:
I did face the 14% problem. I donāt know if that helps in fixing this bug.
Another point to be mentioned: I updated to Cherry 10 days ago. I didnāt face any such problem until yesterday. So, how sure are we that this is a bug due to the Cherry update?
