[Q] S4 mini from 40% to shut down suddenly

[shariar]

i was just on wifi and whatsapp and battery level was at 40% then it suddenly shuts off and i tried to power it on and also tried to take the battery off then place it and start but doest but as i connected the charger it showed 0% and charging... how could it drop from 40% to 0% just like that, and it isn't even the first time it happened, last time it happened the phone was at 20% and my messages come with a vibrate so as it vibrated it hit 15% then another msg and vibrate and it reached 10% then 5% then 4% and at tht point i shut down phone and charged it for 30 mins and it went up to 55% .... can anyone explain ? i have battery guru installed by the way and also 360 security and i have noticed it happens whenever there is a playstore update because the last time it happend and i restarted it had alottof updates...and this time too it had 2 updates that are samsung based apps

download cpu z and check what it says about the battery health, maybe battery is demaged. but it could as well be a system bug maybe...

i wouldn't recommend to try modifieng the phone cause the battery can be faulty if it's really new and you'd just loose your warranty. so just maybe give it back to service. my charger was also demaged from the beginning.

i remember something specific case in both times it shut off, well when i charged and then turned on google playstore and alotta other bunch of samsung apps updated and this time too after turning on it had update for hangouts and instagram, so is it notification and update related ?

well, updates use more battery but the battery should withstand it to some degree. like i said it could be maybe the battery or system bug. but i assume it's the battery

Hmmm....i doubted the same too.. btw is it cause of NFC in my battery ? but you gotta understand its a brand new phone
