You guys are probably in dark room because I can't get these results.

My daily usage is about 1-2 hours talking through Signal, Viber, Whatsapp about hour texting, Safari hour, half an hour Instagram and Tapatalk 1-2 hours.

So when I put to charge, I get 6-6:30h usage and 16-18h standby. When I use camera, I get half an hour less usage so about 5:30-6h.

Auto brightness (mostly over 50%)

Network LTE 60% - wifi 40%

BAR is turned off.

iPhone 7 10.3.3.

Thats pretty much what you should be getting. That is "normal" battery usage under Apple's terms. Your cellular signal strength can also play a pretty big role in it.

Well... Yes and no.

If you see this in tech specs under battery:

https://www.apple.com/iphone-7/specs/

Standby:
Up to 10 days
  • Internet use:
    • Up to 12 hours on 3G
    • Up to 12 hours on LTE
    • Up to 14 hours on Wi-Fi
There isn't any fineprint or anything else where we should know, how we can get these results.

So if we half these numbers to get 6 hours of usage (on wifi or LTE) and let say standby 2.5 days (because 5 days is well... impossible) thats 6 hours of using phone real usage + background usage that you get (syncing mails or just for push notifications) and 60 hours of standby time.

I believe those numbers are basically the optimal numbers, not necessarily average or most common ones essentially.

Yeah, I know, ofcourse, that's why I said this:

Still, can't get that result, not anything near that.

You are missing the key words "up to". Those numbers are in 100% perfect testing condition with perfect cellular/WiFi signal strength. Contact Apple. They will tell you, anything over 5 hours of usage is considered normal. I have even posted direct screenshots from Apple confirming it.

I don't think you understand the standby time. Thats 10 days without touching the device. Put the phone in airplane mode and don't touch it for 10 days. It will last that long.

You aren't supposed to be able to. Its a reproducible <lab test> designed to give maximas and enable you to compare different models tested under the same conditions (think manufacturer's car fuel consumption figures of 20yrs ago before they were forced to make them more realistic).

I agree with both of you, but what we have of lab test results?

How would we know if battery is good? I know Coconut with mac (but not many people uses OSX), but having only to see 24h usage and we are on 3 or maybe 9 hour from unplugging we can't know from where drain comes if it comes.

And we can't have to see background usage separeted from screen on usage in real time not 24h mark.

On this lab results, they say everything is default. So if everything is default, they don't have apps from app store (only apple apps), BAR is enabled, Siri is disabled.

They don't say anything about brightness. This is most important thing for how long battery will last. So at last if everything is default brightness is about 50% (can't remember when I first boot up phone, but I think it was on half of the line).

Try browsing for 12 hours on LTE or 14 on WIFI, lets say if lab is 100%, we can reach (should) about 80%, so it is 9 hours and 36 minutes ( i used 12h mark for 100%). Still you can't reach 9 and a half hour of browsing, even on wifi and 50% brightness on iPhone 7.

You need to understand that even browsing different websites will use a different amount of CPU and therefore battery depending on the graphics etc loaded, there are simply too many variables and pretty much ALL will draw more CPU and therefore more power from the battery than the standard Apple tests.

So in summary, real world usage results in shorter battery life than Apple's standard tests. You are then trying to compare your real-world usage and an unknown battery state with Apple's standard tests and draw a conclusion. Good luck with that - it simply won't work.

Where does Apple.com say that though?

Apple only says "All battery claims depend on network configuration and many other factors; actual results will vary."

If they use the term "standby time," that should be what it means. It's a term of art in the cellphone industry.

Its not that I don't believe you, but there are plenty common terms that are different for Apple devices. Such as hard reset, soft reset and restore.

Hard reset for Apple is holding the power button down and the home button/volume down (depending on device), but for Android, thats a full system reset, or what is a restore for iOS. So some terms have different meanings.

In android terms its soft/hard reboot, in iOS its soft/hard reset.

It's not an iOS vs. Android thing, but rather (to my knowledge) an industry standard term since before the flip-phone days. "Standby" means the handset is connected to a network, able to receive calls.

Here's an official GSMA battery test technique document; see Section 3, "Standby Time Test": https://www.gsma.com/newsroom/wp-content/uploads/2013/09/TS.09-v7.6.pdf#page8

And a CTIA battery life document, which says to use the above-referenced procedures (GSMA TS.09) for testing standby time: https://ctia.org/docs/default-source/certification/ctia_test_plan_battery_life_ver_1_1.pdf?sfvrsn=2

(Apple is a CTIA member, so I assume they have to use the standard meaning of the term: https://www.ctia.org/about/our-members/supplier-members/apple-inc)

I totally undstand what you are saying. I'm not saying you're wrong. I was just bringing up that different terminology does exist and Apple doesn't specifically mention standby means cellular on. Otherwise that makes no sense for MacBooks, iPads (non-cellular) and iPods.
