Android Central Question

i have lg g5 and its about 2 years old. the problem started before 4 months ago. i have even 100% of my battery but when i turn it off or when i take out the battery. i am unable to open even i press power botton. i have to put it in charger for 5 to 6 hours.and then it opens. but i have to put in for this much long before i never had this problems. it would be great if you gave me some suggestion

It sounds like a bad battery. In the future, when you turn the phone off, remove the battery. Don't put it back in until you're ready to turn the phone on again. If it still happens, the battery is bad. That's a bit unusual for a battery that's less than 3 years old, but it can happen, especially if you normally let it run down to almost 0 before charging it.

(If it works by keeping the battery out, there's something shorted inside the phone which would probably require a new motherboard, so you'd have to see whether it pays to do that or to just replace the phone.)
