iPhone 4S Battery Test With iOS 5.0.1

[oshia86]

Like I said yesterday... which resulted in a ton of "down votes", is, this patch isn't going to do anything for battery life.

People are fools if they think it's the software, outside of a few honestly defective handsets, all the rest of us are experiencing exactly what we should be.

The phone just uses more power than the iPhone 4 did.

It's the worlds biggest "duh". So you put a dual core CPU in a device and think it's going to provide the same battery life as a single core?

Either people are stupid, or I'm just really that much more intelligent.

My quad core i7 2600k uses less power than my old AMD 3200+. Are you still more intelligent than everyone else?

Your total disregard for optimizations and architecture improvements is hysterical.

Your total disregard for optimizations and architecture improvements is hysterical.

First off, you're not technically correct, by most measurements the i7 2600k will draw 86 watts at max load, the 3200+ will draw 76.8 watts at max load. Those are general calculations, but still.

However, it's a rather ridiculous comparison, the 3200+ was released over 6 years ago, the i7 2600k is less than a year old.

One uses a 90nm process, the other a 32nm.

It's like saying "My 2011 4 cylinder car gets better gas mileage than my old 1972 v12 did!"

The A5 is not a process improvement, it does not use a significantly different tape out, it's little more than two A4 processors on a single piece of silicon. Of course there are minor improvements in metals, or devices, etc. as have been found during use and testing.

Taking something that uses a certain amount of power, and doubling it by two, means it will use more energy than before.

It's not rocket science.

And yes, I am still smarter than most. Sorry, it's my career.

Well yes and no. You played games for 2 hours 30 mins, and I personally don't play those games, but the iPhone 4S will consume much greater power when playing these games. The majority of results from users in the "Batterygate" thread are from light work which rarely includes games at all. To be honest if those games are pushing the phone to it's peak then this seems reasonable usage. If your intent was to show 5.0.1 usage time for playing games then this is a good start, but is somewhat pointless if you are trying to determine daily light work usage time.

Basically this is a sample size of one without a control. Change this thread into a "Post your 5.0.1 battery results here" thread and then we're talking.

This was never intended to be the end all say so on iOS 5.0.1 battery usage, just a point of data people can look at.

Looks like my numbers were off. Still doesn't disprove my point. Guess which cpu uses less power on a general basis? The i7. Do you know the power saving implementations that Apple used?

Where did you get your numbers? I looked up tdp's for both cpu's and they don't match your numbers.

I don't buy it.

Getting exact numbers is nearly impossible... the only real method that works is to calculate an average based on the hundreds of reviews posted online. It doesn't take long to swim through them and get the information you're looking for.

We're discussing the wrong topic though, the i7 you mention is nearly a technological miracle when put up next to an old 3200+, when you think of the raw processing power it's capable of producing, with the amount of energy it uses, it's nothing short of stunning.

The real conversation is the A5, it's just an A4 x 2.

You can't expect real improvement in anything but performance.

Thats fine, you don't need to. I can't get into any greater detail anyways, not that it would really matter. My opinion is mine, yours is yours. At the end of the day, we both have an iPhone 4s and we both get very much the same battery life out of it.

 

[oshia86]

Have you actually used many reviews to calculate your averages? Looks like your numbers were as erroneous as mine.

I agree, that it will use more, when maxed. However, we don't generally use a cpu's full potential on a normal basis. Is there any single app that would utilize both cores to the fullest? Games? I don't know. Just doesn't seem like we are gonna see a twofold power consumption increase from the cpu. What about the other components in the phone? I'm sure the ram and memory have been improved. I might have to research this more.

I've also seen quiet revisions (q6600 B3 and G0 for example) provide the same product, with a much lower vcore and overall power consumption. Who is to say such a thing is not in use?

You and me both.

do we really need 2 threads? Moderators do your magic and combine them!

Maybe so, remember their first reaction to Antennagate? They said it was a software issue, that the bars were inaccurate and released a patch. Let's wait and see.

I didn't realize you were an apple engineer who knew exactly how iOS works there are always things that can be optimized, such as drivers, services, etc.

There are posts all over the web referencing the standby time and background processes with regards to the battery issues. Active usage is not where they (Apple) have acknowledged issues. You don't have to be an engineer to know these things; you just have to be able to read.
