Upgraded from iPhone 14 Pro to iPhone 16e and I’m really disappointed with the down/upload speeds. Connected to the same network, speeds are as follows:

iPhone 14 Pro
Down - 550mbps
Up - 45mbps

iPhone 16e
Down - 200mbps
Up - 3mbps (yes three)

Could the phone be still indexing in the background or?

As I use my phone to hotspot all through the house, the performance is extremely important. At the minute it’s lacklustre. Any ideas?
Problem is you downgraded not upgraded, there’s your problem:). Like I have a MacBook Pro M1 Pro, you would think a new m4 MacBook Air is an upgrade but it’s actually a huge downgrade
 
I mean you as in I bet you think a m4 is a huge upgrade but it’s not just like u think 16e is an upgrade over a pro lol I’m rocketing 11 pro max btw in midnight green :)

did the 14P use mmWave? if so, the 16e/C1 modem does not support that.

I see these kinda high speeds on my 13PM when connected to mmWave, not 5G
I see those speeds and higher with a good 5Guw connection on Verizon.

This isn't the case of C1 modem vs. modem in 14 Pro, or from a hardware perspective 16e vs 14 Pro. The 16e is more than capable of delivering similar speeds on the same network - there's definitely some other (external?) factor that's causing the 16e to underperform. The 16e is definitely a downgrade in some aspects, but compute wise the 16e would win as it's running the latest SoC.

No surprise given that the C1 was derived from the awful Intel baseband tech that Apple bought.

I’ll never forget how my Qualcomm iPhone 6s performed better than my iPhone 7. Even in good signal areas, call audio used to drop constantly. Never again. Nothing beats Qualcomm cellular basebands in terms of quality.

General tests for the modem are positive and show much faster speeds than that. You might simply have a bad modem. If it doesn’t improve in a few days, get Apple to check it out.

indeed, interesting results.

i can see how disappointing those speeds would be for the original poster, given his use case is at a static location.
its all and only about speed.

but for most users of a mobile phone, it is not entirely about download/upload speed.
almost as much important, at least for me, is how efficiently the cellular modem is seeking a signal.
and, if the rumours of the C1 are accurate, the C1 supposedly excels at that.
so, especially in the upcoming iPhone Air, with reportedly battery capacity issues, a C1 would be welcome.
 
It looks like Three operates its 5G service over bands 29, 77 and 78. The iPhone 16e only supports bands 77 and 78 whereas the 14 pro supports all 3 bands.

Actually scrap that they both only support bands 77 and 78, assuming you have UK spec.

Got a question that isn't related to the modem performance.

Is it normal for people to use phones for hotspots in the UK?
Cuz if you'd used 4TB on your unlimited mobile plan, the carriers are going to come at you with their entire legal team here in the US or you'd be banned permanently.

Also, with that kind of load, you'd be wearing out your battery quite fast. Not sure if Apple stress-tested their modem to this level, but I'm positive that's not going to be good for your phone in the long term either.

That’s actually hugely inaccurate as for CPU performance.

That sounds frustrating. It’s bad enough that the download speeds are 2.75 times slower, but it’s even worse that the upload speeds are 15 times slower.

I have two questions:
1. Were you using a SIM card in your iPhone 14 Pro?
2. If you were using a SIM card in your iPhone 14 Pro, did you use that exact same SIM card (not a new SIM card) in your iPhone 16e?

Wild You try to compare a Pro phone with an E, where the 16e was made as a replacement for iPhone SE, so You should compare these 2 to see what's the difference and then complain if the results are worst than iPhone SE
 
But why would I? I have been hotspotting for the past 2 years now without any issues, I even created a thread about it - https://forums.macrumors.com/thread...using-14-pro-as-a-hotspot-for-months.2390496/

Sure I could do it, but why pay extra?
Well that’s up to you, most people have a fixed broadband connection as well as a phone. So that there is always a connection at home for other devices.

If you just want a phone you should have investigated its cellular connectivity specs more before buying. It seems like you don’t look at the difference between the 16e and previous iPhone.

Something is wrong here - in general the C1 ought to be more performant than the iPhone 14 generation. In the real world, it ought at least to be equivalent. Most testing against the iPhone 16 generation finds it on par, winning some and losing some but never to the massive degree you are seeing here. And it’s not a mm wave issue as this is the UK where mm isn’t used.

So your options are something fishy with the specific phone, or some specific issue with 3. Is it possible that there is an edge case here with 3 making heavy use of some particular bands in your area that are supported by the 14 pro but not the C1?

I don’t know about elsewhere in the world, but I have tethered a lot here in Australia. I’ve even paid for an unlimited day so I could download a great deal of data at speeds much faster than the fixed connection at that location. It’s not a problem here.
 
I mean it's a valid question and as others have stated the 16e is hardly an upgrade over a 14pro. Depending on the reasons and considering it worked better before, why not just get a new battery for the 14pro?

Yes.

You may get throttled here after a certain amount, but the threshold varies wildly between providers and plans.
 
I'm not quite sure how much is guaranteed and whatnot, but all I am saying is that the performance of the C1 is a bit of a letdown at the moment. I got an average 500+ Mbps with my 14 Pro. Now I'm struggling to reach 200mbps. Hmm... I might have to return the 16e.

I agree this is disappointing and I would get in touch with Apple directly to try and understand what is causing it. If this is a missing band issue, as some here have suggested, then you are out of luck, so could consider returning 16e and getting a regular 16 instead, which will drop down in price anyway once 17 are out. If you need it now and don’t care about Apple Intelligence, you could also consider iPhone 15, which is also good (I use it).

My current mobile plan gives you unlimited hotspot data and unlike overseas(USA etc) it is actually UNLIMITED. You see some things are actually better in the UK.

I moved over to the 16e because I wanted a lighter phone. 40 grams is actually a noticeable difference. I was hoping that the 16e would be able to at least match the performance of the 14 Pro but at the moment it's not getting anywhere close.

Also both phones are using eSims.
 
Check with your carrier.
I'm in the UK we have no mmWave in this country. I guess this may show if we see more results that the 16e performs better in the US because Apple designed it for US possibly, Qualcomm modems like the X85 are top notch and not the new kid on the block. Another reason I'm thinking of jumping ship.
