Apple support not helping

Please does anyone have any advice?

I am getting nowhere with Apple support.

I bought a new iPhone 11, summer 20 from the Apple shop

near me. I have the receipt which I have already sent apple as proof of

purchase.

It ran fine from August 20 December 20.

I am a prolific phone user and use my phone for

everything - Facebook, mumsnet, messenger, WhatsApp, emails, everything.

My problem with my battery dying is sporadic, it doesn't happen every day.

But other days when I work from nine till three I hardly

use it at all I my only send my husband a couple of texts.

Around Christmas time I noticed that on the days I do

work, with minimal usage, the phone was dying at about 2 pm.

I took photos, as evidence, to prove this, suddenly at 2 pm it would be

12%, 6%, or 2%.

I contacted Apple support in February 21 and I've had 30+

phone calls with them including one today.

I also took it back to the Apple Store and they run

diagnostics. Battery good. and he claimed that as far as they were concerned there was nothing

wrong with it. nothing wrong with the hardware or software.

He suggested I dimmed the brightness on my phone and

asked whether I had any background apps running behind the scenes using

battery life without my knowledge. I handed my phone and asked him to look

and turn any that I had running off. he reviewed it and said oh you hardly have

any, there are three here, shall I turn those off, which I replied yes.

He said run it will run it like this for a week and see

if it makes any difference.

I felt like I was being fobbed off and told him so. like his desperate

attempts reeked of desperation. I said to him ; you don't know what's wrong with

it do you? I said I feel like you're not offering me any proper solution, it

reeks of desperation, like a sticky plaster, you don't know what to do.

you're just suggesting I dim my brightness are you seriously suggesting that

such a minor thing would correct a major fault such as what I'm telling you I

have?

He was ice cold and said a diagnostic test show there's

nothing wrong with the hardware and nothing wrong with the software.

I feel like standing in a court of law and screaming in

frustration. apple insist there's nothing wrong with this phone. but I use it

every day and I'm telling you the phone dies in the middle of the afternoon, sometimes,

even on a day when I'm at work with minimal usage.

I feel like this phone isn't safe. I've had iPhones for 20

years. this is the first brand-new one I've bought from the shop.

I'm a diabetic I don't want my phone dying. I want to know

that it's safe and secure, so if I have a diabetic hypo I can phone my husband

or I can phone and ambulance. I don't feel safe - I know that sounds dramatic and

I'm milking it a bit.

I feel like I've got nowhere left to go because it's now

gone past work August I'm now out of warranty. I feel that they deliberately

dragged my case out for as long as possible so that on my phone is now not

in the warranty period.

I feel a stalemate because they say that there is

nothing wrong with the phone, and I insist there is.

I'm going to the Apple shop again this Friday. I have asked

for a complaint many times. this has not been activated. I have asked for a record of all my phone calls. I have emailed

apple. I've tried to get this escalated. I've tried to make complaints. I've got

nowhere.

Every time someone promises me something, they make no notes on the account,a dn then the next person denies accountability.

I feel powerless.
