Help Battery life acting.. weird?

[MultiFrapser]

Hello. I started to notice this problem a few months ago, but I think it has got a bit worse now lately. Let me explain what is happening and why I need some answers from you about what could be the cause of this issue and the possible fix?

So, I have let us say 45% of battery left on my phone. But if I open any of the following apps: Google maps, Snapchat & Google Search but battery dies instantly or in a few seconds. Then my phone reboots itself and now claims to only have 1-5% of battery left, then it dies also quite quickly. Until I put it charging it wont reboot and turn on.

This is quite odd because it should be working at 45% very well, sometimes if I happen to put battery saving mode on then it will work quite long to circa 10-15% of battery.

So, what could be the cause of this? It can not be my charger because I have bought a new one after the old one broke.

Your power remaining is based on the voltage output of your battery. Batteries are made up of individual cells and if one of them is failing, it would explain a sudden drop in voltage.

Hm alright, so would simply a new battery fix this problem?

That is a classic symptom of a bad battery. If that is indeed the problem, it would fix it.

Alright thanks for the info! I'm new on these forums and tbh had no idea where to get help, I'm not an expert on smartphones you see

You might need a replacement.
