S3 Mini restart/switching off by itself problem

[Walter5850]

Alright,
I have bought the new battery and I CAN confirm that it DID solve the problem.

I've been using it for around a week now, and the phone works as new.
Haven't had any random shut downs or any problems of that sort.

Personally I just bought a cheap battery from "Miniinthebox" for 6 bucks and it works perfectly well.

DO NOT replace the battery! It doesn't fix the phone. I have this problem and seeing as the device is under warranty, I will either return it to the store where I got it from or send it to Samsung. I used to love this phone when it worked, but I'm getting frustrated.Mine turns off at 35%, without no warning. So don't replace the battery, just see if its under warranty and get it replaced or refunded. I will proabaly get an iPhone if I manage to get mine refunded from the store.

My samsung grand prime restarts itself when not in use. I will leave it to sleep and it will auto restart itself.

Anyone know how to fix this?

There are a few possibilities.

Look in Settings/General/Battery. Tap the graph to get to the second page. Look at the graph. If you see a sudden drop to 0, your battery is growing a dendrite and has to be replaced. (They're under US$10 at Amazon.)

I started getting this restarting problem after I got soaked in rain and the phone was in my pocket. I never had this problem before even though my S3 mini is at least 3-1/2 years old. Mine restarts during calls mostly

Its been almost a year now since I've had this phone. Recently, my phone has been restarting/switching off by itself....once it turns off, it won't turn back on again unless I plug in the charger. If I try holding on to the power button once it happens, the "S3 mini logo" just keeps showing up and switches back off again. I even did a factory reset and still it didn't fix the problem. Even when I try going through my phone (reading messages, going through settings, opening an app), it'll just automatically have the problem again and switch off again. One time I kept my phone on sleep mode for about 5 hours, and after that I just wanted to make a phone call and again it just turned off.. please any help would be appreciated..

I was suggested to change my battery inside the phone and buy a new one - will that fix the problem or make a difference? if not, what suggestions would you make? Anyone has been going through the same problem with other devices or this one in particular?
