Charging symbol is there but won't increase and sometimes decreases
My phone is plugged in and has the charging symbol but the percentage won't increase and sometimes decreases. I have tried using a different charger but it has no effect. I've left my phone on charge overnight but it stayed the same percentage as before I went to bed. Sometimes I see the percentage jump around (eg. From 26% to 20%) even when it is on charge. Once I noticed it was in the 20%s and ten minutes later was on 1%, all while being plugged in. I've had the phone for 1.5 years and it has never been serviced. Should I take it in to the apple shop and get a new battery?
Is this a good question?
