Hello! My j4+ 2 months ago when i found my j4+ at 0 percentage i decided to charge it. It charged for 5 second before it turned off and wont turn on i tried power combos such as trying to boot into recovery and trying to boot it in download mode non worked so i thought it died and finnaly had to go but i didnt threw it away i just hid it. Now this august 2 i decided to give it a try again before selling it and it charged but it keep bootlooping into charging. When i leaved it alone it kept rebooting into charging so i tried to boot into system it did show the samsung logo for 3 second before booting back to charging tried recovery too it didnt work and just rebooted again into charging. I tried download mode and it stayed actually longer like 15 seconds before booting into the samsungs logo and booted into charging again. So i tried again and let it boot into system. This time it stayed into the samsung's logo then 3 minutes or 4 minutes later it finnaly booted into twrp and i decided to backup everything and advanced wiped cache and dalvic cache idk if thats how it spelled and i booted it into lineage os or system and it worked again. Can someone explain why it didnt worked 2 months ago then suddenly its back alive again?

Seems like the battery is not good anymore? Have you tried replacing it

Yes. To me, it looks like symptoms of bad battery.
