Phone died very fast

[Anati_dar]

The other day i was walking home quite late with my phone on around 20%-18%, I had nothing running on it but spotify (I closed all background apps and had power saving mode on) when randomly my phone turned itself off? When it turned on it was on 2%?

This put me in a really dangerous sernario walking around dark streets alone in the dark and no way to contact anyone?

I would like to know the cause of this as I can't risk it happening again.

Hi
Check what apps you have running in the background that may be draining the battery

Sorry I did say I checked that all background apps were closed

Hello 👋 @Anati_dar and may I extend a Warm Welcome to the Samsung Community Forum. 

I would suggest to again double check what's using your battery in your Device Care Section. 

You can also help the phone via > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

Try to ensure the phone js charged before going out and use the phone's Power Saving option if necessary. 

I also carry a portable Powerbank too.

Hi @Anati_dar  Welcome to the Samsung Community   

Which model do you have?   Battery  does drain faster when it is around 15 % and Spotify can be a bit  of a Battery Hog, there are certain tweaks you can make https://www.headphonesty.com/2024/11/spotify-drains-battery-faster-most-music-apps/

Was it just last night or have you noticed more general Battery drainage?  I would suggest you have a Battery pack with you for charging on the go (particularly if unable to use a wall charger or wireless before  reaching lower levels)  one example here https://www.samsung.com/uk/business/mobile-accessories/battery-pack-20-000mah-beige-usb-c-
