It’s much hotter than the 8 Plus, which runs cool.

Under what circumstances? what apps? how are these metrics being recorded? just saying so on the internet doesn't make it true.. please provide a source.
 
X has a (tiny bit) bigger battery than the plus, but a physically smaller screen hitch is also more energy efficient. FaceID likely to require more power than touchID. Everything else should be a wash (same internals).

So wouldn’t you expect battery life on both to be similar?

Yes, but not sure why these YouTube tests showing 20% better battery life on the X over the 8 Plus ?

They should be equal, and if anything the 8 Plus slightly better.

I never judge how good a new phones battery is the first few days. I’m always playing with it and generally will favor it over the other devices, for at least the first week or so.

I figure after the first few days the newness wears off and then I can see how long the battery lasts with my normal usage.

I’m happy to report back in a couple days. The battery for me is such a let down so far. But I like the phone, and I agree it will be better when you aren’t on it non stop.

Based on my real use of both devices. It’s markedly different.
Proof and use case? Markedly different, meaning what? That with one you can get through a day but not with the other? If you can't get through a day, what does a day of use for you look like? Not implying anything, but the way most people are glued to their screens constantly these days it's a wonder people get through the morning. For mine, all notifications are off except for WhatsApp and iMessage. I don't pick my phone up the second I get a message either, I get around to it when I'm ready. Rest of the time is casual use. I'm at a laptop most of the day anyway, so the only time battery is an issue is if I'm going to be away on business at a conference or something where I'm on it all the time. Rare, and even then it only needs a small power pack in the bag or pocket to eek out the rest of the day. When you can get a 7 day week out of a phone like we used to before things went smart, then I'll sit up, take notice, and say there is a marked difference.

Not to mention are they using an apple watch or not? I check my phone about 2/3 less when I have my Apple watch on. Are they using a headset? Is it wired or wireless? There are so many factors to take into consideration.

Definitely not experiencing much heat with mine so far. Set up as new. It already downloaded the 7000 or so images from my iCloud library, etc, though I’m sure there’s some background indexing still.

Also, I’m noticing a recent YouTube update seems to be draining silly amounts of battery in the background.

Day 2 today, mainly WiFi browsing with safari and twitter with some light photo editing, currently at 3 hours usage and 7 hours off the charger at 67%. Comparable to my 7 plus.

My 8 Plus consistently delivers an hour and a half of useage at the 90% mark. The X seems to be an hour and a half of use at around 80%. Yes it’s new and yes I’ve been on it non stop. But if I were in the 8 Plus non stop I get to 90 after an hour and a half or close to that. Same setting etc.

That's an assumption.

More likely the processor was deliberately under clocked (optimized) for this form factor. As the narrator explains the iPhone x is pushing significantly more pixels than the plus. When you combine that with the slightly higher capacity battery of the X the numbers start to make sense.

Narrator is wrong.

The "pushing more pixels" myth only makes sense to people who don't understand how the iPhone graphics system works.

The processor speed of the X is all over the Internet. There's no underclocking going on.

This is actually incorrect. A full white screen on OLED is more power efficient than an equivalent LCD at similar brightness levels.

Nah. I'll trust DisplayMate instead, thanks.

While LCDs remain more power efficient for images with mostly full screen white content (like all text screens on a white background, for example), OLEDs are more power efficient for typical mixed image content because they are emissive displays so their power varies with the Average Picture Level (average Brightness) of the image content over the entire screen. For OLEDs, Black pixels and sub-pixels don’t use any power so screens with Black or dark backgrounds are very power efficient for OLEDs. For LCDs the display power is fixed and independent of image content. Currently, OLED displays are more power efficient than LCDs for Average Pictures Levels of 65 percent or less, and LCDs are more power efficient for Average Picture Levels above 65 percent. Since both technologies are continuing to improve their power efficiencies, the crossover will continue to change with time.

So at the moment I’m at 71% with 2 hours 11 minutes of use. On the 9 Plus I would be around 80% with that usage.
 
The only let down for me on the X is the battery life. I’ve gotten used to the smaller usable screen size. My hand doesn’t cramp typing on the small keyboard anymore (it did something awful at first.) The X looks great, Face ID, when you experience it first hand is a much more user friendly experience. I woke up this morning thinking I could sell / return the X as opposed to selling the 8 Plus. After using the X again, I just like it more even though it’s battery let’s me down. Excuse this analogy: the 8 Plus is like the girl you dated who did everything for you tolerated all of your moods, the X is like the girl you chose instead. Ugh!

that sounds terrible. a small crash that will end fast :(

Cheers. Be interesting to know how this compares to the standard 8.

Trust whatever you like. All I know is that my 55" OLED with a full white screen draws less power than my 55" LED with a full white screen. In fact it draws way less power full-stop. There are far more factors at play when it comes to power-draw though, but then you're clearly an expert so you'll Google it and get all the facts I'm sure.

As a new X owner, it isn't going to get better battery than the plus models.

My battery "stamina" has improved BIG TIME over my 6s Plus . . . . daily usage is the same but more battery charge on the X (as compared to my 6S Plus) at the end of the day. Just my personal experience :cool:
 
I'm getting ~25% less battery life vs my 7 plus.

It's kinda disappointing :(

Sorry, I'd be a bit disappointed as well. My experience , albeit 6s Plus and not a 7 Plus, has been quite the opposite . . . . dancing in the street. :D

That fact that you assume a TV is comparable to a mobile application is really something.

Apple uses expensive low power LTPS LCD panels which are limited to mobile applications. Your 55" TV doesn't use that tech.

Please don't make random comparisons.

Way better battery life on my X compared to my 8 plus. 6.5 hours of screen on time with the X. 95% brightens. Same usage as my 8 plus.

Funny then, how it was OK to make "random comparisons" when you quoted your Google research! lol Only when you get shot down do you resort to claiming it's a random comparison. By your same argument, there is no comparison between the LCD of an iPhone Plus and the OLED of an iPhone X, so what the hell are you harping on about lad?!

Fact - my 55" OLED draws less power, picture-for-picture, than my 55" LCD, both made by SONY, both with similar picture processing inside. Draw from that what you will, but don't go shooting down your own arguments in the process. Makes you look silly.
 
It’s opening weekend. Phones will be restoring from backups, downloading apps, indexing/whatever and generally being used a lot as people are fiddling with their new toys. It isn’t surprising if people aren’t seeing great battery life, but it may not be representative of normal use.

I really don't believe in anyone's SOT anymore since everyone uses their phones differently. Some days, I might browse. Some days, I will tether it. Some days, I will take notes or read.

Had three phones with LCD and two phones with OLED. They generally all gave me the same amount of SOT. I can go 10-11+ hrs SOT on an iPhone SE by just browsing. If GPS and 4G data on, it gets cut by more than half. If tethering, even worse since Wi-Fi and Bluetooth need to turn on although I do turn off BT once my other devices are connected.

If GPS and data is all on, I get the typical 4-6 hr SOT. If on Wi-Fi, I can go beyond 6 but only if browsing. If gaming, less than 4. My phones also need to be quite bright throughout the day. Some displays are dimmer by default. A phone with 70% could match another one only set to 50%.

I find most battery tests unrealistic to how I use my phones. Even TechRadar's doesn't apply to my usage. SOT could be all over the place depending how you use your phone that particular day. As long as a phone can last until I go home from work (11a-8p), I'm good.

Well, pleasantly surprised this morning. I have 2 hours of standby and 59 minutes of use, and I'm only down 3% so showing 97%. That's actually pretty impressive. My home is in a not so great coverage area. I'll see how the X does today, but feeling much better so far with the battery on day three.

Even Apple says that the iPhone 8 plus battery life is slightly better than the 10 or about the same
