Brand new iphone 6s

[Bronzefi3nd]

So i have purchased an iphone 6s last week and i am encountering some problems with it.

First day it came, it charged really really slowly, it barely had 22 percent after one hour plugged(powered off straight out of box). It eventually charged 45 percent and i had to leave so i took it with me. After couple hours, at 30 percent battery it powered off randomly. I tried to power it on and after showing me that no battery animation it would power on and power back off after some seconds.

That happened on ios9. I proceeded to update it next day to ios11 and this stopped happening but instead something else happens now: sometimes the battery would drain incredibly fast, mostly starting from 70 and under at a rate of 2percents/minute. This happens only when playing/browsing and if i realise it is draining and closing apps it would stop.

Notes:
Under “battery” there is nothing unusual.
Under “Background app refresh” there is nothing checked.

Anyone else encountered this kind of problem? Any clue to whether it is software or hardware related? Thanks to everyone in advance.

So, where did you purchase that iPhone?

 

[Bronzefi3nd]

I bought it from arguably the biggest phone retailer in my country.

So, don't lose any more time, straight to the shop and demand a replacement!

iOS 9? How did a brand new 6S come with the the OS it had from 2 years ago? Is it over 2 years old and just never opened? Regardless, I’d retore using iTunes and set up as new without using any backup. This most likely will straighten out any software issues you’re having. If it’s a hardware issue you’ll know after you eliminate the software side

I believe they all come like that, check gsmarena.

The iPhone 6S were recalled because they are defective. Mine had to be replaced because it was doing the same. That’s why Apple started slowing down iPhones - they saw through the 6S what was happening to all of their faulty devices. You need your entire battery replaced, but if running iOS 9 it may not help.

They didn’t cripple their phones until 10.2, so your new battery will eventually start doing the same thing. They used a battery recall to hide the faulty CPU/battery symbiosis.

Nice theory. My 6S has worked flawlessly for two years and counting with the original battery. Apple had a service bulletin that said if your phone fell within a a certain serial# they would test and if necessary replace the battery. Samsung had an actual recall of their note7, big difference

Because it’s running an iOS version 10.2 or later, right? Hence the CPU draw problem not causing it to shut off, they’ve throttled it.

No, my battery is 94% capacity and I have posted geekbench results at 100, 50 and 3% and show no difference in results

People have run Geekbench while their phone was plugged into a wall charger and their devices were still throttled. Someone recently just ran a Geekbench on their iPhone X and it was running at 50% the processing cores that it’s capable of. It’s the version of iOS that matters not your battery health. That’s just legal talk for the lawsuits...

So you actually think my geekbench scores are falsely inflated by geekbench themselves? Or are you saying Apple is using software that notices geekbench is being run and giving false results? I love when people throw blanket statements out as if everyone’s device is performing the same. The geekbench results on my phone have been run thousands of times since it was new and have never changed. My phone is running 11.2.1 and is not throttling ever... If your does, replace the battery and the problem is gone.

It's not just the iOS version that matters when it comes to that kind of thing.
