Phone went from 20+ to flat and turning itself off in a few seconds

This is the beginning of the end, right?

I hate having to get a new phone. Could really do without the expense and nothing works as it should.

Mine has started doing this too.

Sympathies

Is there an option to get the battery changed?

I think I do usually look at that and it costs more than the phone is worth.
I don't want a new phone. I just want my old one to work forevermore - is that too much to ask??

My phone is starting to run down pretty quickly too.

Guessing it's an iPhone...

@StealthPolarBear Is it a Samsung? Their batteries were always rubbish.

My iPhone X is dying a slow and determined death, I carry a small power bank now if I'm out of the house for too long.

I'm furious as the newer phones don't seem to do that much more for the extra cost, and the money I've saved every month is embarrassing. Previously I was a dedicated phone geek and had a new one every two years, often on the day my contract expired. Now I'm scandalised at the cost, not to mention the sheer waste

Mines doing the same. I hate new phones and I'm not sure I can remember the passwords for everything

Often a factory reset will fix this issue though it's likely to come back in the future. It may buy you a few more months though.

It's a Sony. That's was the first time it's done it so might be a one off
