5G Drains iPhone 12 Battery 20% Faster Than 4G in Benchmark

Super inefficient use of a battery to have it dissipate energy that way. If you are going to the effort to use a battery case better to plug it in and not lost so much power.
1) Running at 20mph, takes 10 hours to completely run out of gas
2) Running at 25mph, takes 8 hours to completely run out of gas
Car 1 traveled 20*10 = 200 miles.
Car 2 traveled 25*8 = 200 miles.
Both traveled the same distance, 200 miles, but the second car did it in less time.
So car 2 is better.

Promotion isn’t a big deal at all, have it on iPad and really can’t tell. Maybe on a iPhone it will be more noticeable? But tried a Samsung and it was choppy, so who knows
I'd be happy if my LTE was faster than 1Mbps in my rural area. 
Wow you are so smart. You are lucky
Probably normal 5g, since they're probably doing this in a building (their office, writer's home, etc.) and mmwave wouldn't even be an option in that case unless there was a tower in your front yard and you had line of sight through a window.
makes you wonder if Apple spinning another "smart" with the dropping back to LTE "when 5G is unnecessary" i.e. it is more likely "when needed" to preserve battery power which they know is already compromised
I don't care for 5G for the moment. It'll take years for mass adoption and mmWave just sucks if u try to use inside a building, and the fact there is a pandemic out there makes even less appealing. I mean, why buy a mmWave phone if you gonna stay mostly indoors for the next several months?
Time available to use the phone is more important than time it takes to download something. You wouldn't use a phone that could download an entire 4k movie in a nanosecond, but used up 90% of the battery to do so and left you with insufficient battery to watch the movie, would you? The goal should be to maximize usable time, while offering as fast downloads as reasonably possible without cutting into usage time.
No its not? It is becoming widespread and if you are in decent locations you can be on it 80-90% of the time...and let's not forget, this new phone is for the next few years when it will become more widespread. My daughter uses a 5G dongle rather than fibre broadband and she does abolutely fine with it.
if its not available, and your plan doesn't support it, it wont be used, so no to need to switch anything off?
I have a 5G phone and have never gotten 5G, the speeds of the 4G are still like what I was getting on HSPA+ lol... so I doubt I'll even see 5G for 5 years lol.
it's a good thing new iphones have superior battery life. oh, wait...
I still keep my phone in 3G mode as 4G in my area is pretty weak. 5G will be even weaker, I'm sure.
Of course not, but this is not the case here, your numbers are totally out of reality.
5G is much more than only 20% faster than 4G, and consumed only 20% or 25% more battery per second, so it's better.
Do you want 3G at 1 Mbps with a 20 hour battery life?
Or 2G at 0.05 Mbps with a 30 hour battery life?
No!
The goal is to accomplish a given task in less time. Since it consumed less time, although using more battery per second, it will still consume the same battery or even less battery in total... and taking less time!
I don’t get the relevance AT ALL for this test. Apple has already told us that the phone will be using 4G most of the time, and only upgrade to 5G “when it’s needed”. Surfing the web like the user did in the review will definitely not activate 5G. So the test is very artificial. Also, would any use even activate 5G for a prolonged time? Like streaming 4K video straight for 8h? Who even has that many GB in their plan? It must be crazy expensive.
During normal use I’d guess 5G is only activated sporadically. So instead of 20% battery loss, I’d really chocked if the loss was more than 5%.

And how long will that battery last when the phone is 3+ years old and 5G is more widespread? More than 5G, OLED, A14, etc the single feature that I would like the most in a new phone is a user-replaceable battery.
Ah, tell that to your spouse as they are trying to call you on the way home from work and your phone is dead.
Prior you would have had an hour or 2 of phone use left still.
In this case "Car 2" ... sucks.
This is exactly why I am waiting for next year (or the year after). This will give Apple/Qualcomm some time to figure the battery drain issues out.
Except this test disproves that.
If this test showed that the 5g radio used more power, but was able to counteract that by running for a shorter amount of time - then the test would have concluded with the 5g phone winning. The 5g phone lost which means that it both uses more power (this was obviously known) but also isn't able to leverage its faster transfer rates to mitigate the extra power use (by finishing the task faster).
Tell your spouse your phohe is a Chevrolet Camaro SS V8, not a Honda Civic... 😀
Apple said it was a Speed event. So they didnt lie, even the battery drains faster
