annoying galaxy s4 problem

[Alaa Masoud1]

hello

bought mine 2 mounth ago and just before two days my phone start acting strange , like when its charged as example 70 or 80 or 50% it suddenly shut off and restart . after restart the battery percentage show battery level of 0% and it goes off because battery low , but i know it has power inside

some times it stay like that and back to work , other times i need to plug it in the charger and once i did , it show the real percentage it was had before


im sure some of you face this problem , is it the phone hardware problem or is it the battery ?
also before this problem happen i was always amazed how fast my charger is , its the original galaxy s4 charger but the charging time are super fast
like it need one hour to go 100% from zero% and for a 2600mah battery thats a real good thing
so i guess it has something to do with my problem


thanks

Place your battery on a table or other flat surface. Push down on one corner and see if you can spin it. If it spins, it's starting to swell and the battery is bad.
