iPhone 7 - 87% battery health - "significantly degraded"?

[NewBench]

This is my second iPhone 7 in 3 days having replaced the first one due to other issues. Checked the battery health on this one and it says:

------

"Important Battery Message - Your battery's health is significantly degraded. An Apple Authorised Service Provider can replace the battery to restore full performance and capacity"

Below that, maximum capacity shows 87%.

Under 'Peak Performance Capability' it says "Your battery's health is significantly degraded and peak performance may be impacted".

------


From google it seems that a few people have had this message, but it was blamed on a bug. I got this message today and the phone is running iOS 13.6.


Does this point to a faulty battery that needs replacing or just a 'bug'?

I’d say you got an old battery. Where did you get the phone? I would take it back if possible and get a replacement unless it was purchased as a used device

It's a used device from a place that specialises in selling used phones. I was expecting it to have less than 90% battery health as it was used, but I've never had the 'significantly degraded' message before on any iphone regardless of battery health %. Had a 6S a few weeks back that had 84% battery health and it didn't have that message.

If the phone is displaying that warning it means the phone will likely not perform normally and provide a bad experience.. If you want to keep it you need to get the battery replaced or it will give you trouble

just replace it. it may not have big juice like iphone 11 but still can do one day if non high usage.

Get Apple to put a new battery in your iPhone 7.

Just had a look at battery health today...left it at around 20% this morning at 00.30am, it's now at 2% at 12:30pm with zero usage/just on standby, no apps running in background etc. Is that normal?

Going to take it back to the store tomorrow, hopefully negotiate either a new battery or a replacement.

some technician said to me if you have 80 percent health mean in 20 percent will kaput.Once i got sudden shutdown even 8 percent so basically better change and have power bank on the go.

What's the signal like where you are? A good amount of battery is used to keep up the phones connection when the signal isn't great.

I'm on O2 in the UK. Their service coverage checker shows excellent indoor/outdoor 4G + 3G coverage. Phone shows full 4 bars probably 90% of the time, very occasionally 3 out of 4 bars but always 4G.

Honestly I think 20% battery decrease after 12 hours of stand-by is not too bad (if you had data turned on at least). But this battery warning is a bad sign, in my opinion much more worrying than the 87% performance.

I used to have an iPhone 6s that showed something like that and even opening an app and read a few websites on the way to work would often drain the battery to 20-30 percent. I basically had to carry a power bank with me at all times. Also, there was a pretty sudden drop in battery health from like 80 to 70 percent.

I would return the phone, they gave you one with an obviously degraded battery.
