How many dots are strong signal? 4/5 from 5? 🙂 because at work mostly I get 3 from 5 however I use WiFi but also keep turned on cellular.
Got a tip for us?

Dots are not a linear representation of signal strength, unfortunately.
With 4/5 dots you surely have a good signal. 1/2 are a very poor signal, barely usable especially for data exchanges. 3 dots are a gray area: it could be good for a phone call, but hard for data exchanges (thus an high battery drain).

. It's a logarithmic scale and 4of 5 is not a great, but good signal. 5 is better , but in actuality , the scale, fully represented graphically ( and just from memory with research I did during the antenna gate days) the scale could go up to 10 dots at least. Basically 4 of 5 to 1 of 5 covers a factor of 10,000 signal strength variation ( not linear as you said). But 5 of 5 and the unreported dots above 5 of 5 covers another factor of 10,000. ATT once stated, for the iPhone, 3-4 bars or dots was a poor signal area.
A 4 of 5 in the iPhone 4 and you could observe an antenna gate problem. 5 of 5 and above, you were good.

Just an example of the battery not self draining. Keeping the screen off is a big factor.

You need to do one of, or a combination of:
Deleting and reinstalling your email accounts.
Resetting network settings.
Resetting all settings.
You obviously have something wrong there, and the background activity gives it away.

Since 4.0.1, this has been changed to be more linear.

I would disagree with "obviously something wrong". Qver an hour of use and 86% with almost a full day of standby is not obviously bad battery life. Pretty normal I would say.
Assuming this is a 6+
per Apples spec, 384hr standby and 12hr wifi/lte use
stdy =22hr 45min
use= 1hr 10min
22.75/384=.059 (6%) used stndby. 1.25/12=.104 (10%) wifi/lte use so 100%-(6+10)=84 so should see about 84% remaining. He had 86% so seems like good battery to me.

I wasn't really commenting on battery life, more the 'background activity' in apps which pretty much never say that. I had that issue before and resetting all settings (plus the subsequent re-toggling) fixed it.

Oh sorry, wasn't thinking that. However background activity is normal too if its turned on. Looks like he has stocks and photos in the background enabled. So in that case this too would be normal.

If enabled, yes sure. I kinda fired my message off and should have said 'if this, if such & such' etc. I would just assume within my own set-up that too much background activity meant an 'issue' was present. Not necessarily for everyone though.#

That article is quite old.
Since iOS 7 dots took place of bars, and we don't know the algorithm behind....

I think it can be easily measured by field test menu whereas instead of dots are being shown by dBm 🙂

Which is exactly what I did with my 4 and 5 models.
Basically the dots show the very bottom of signal strength scale. 1-4 and you are in a weaker area and to expect variations of quality and speed. In a city near towers when it says 5 bars or dots you may really have a 10 equivalent. Something near -40 dBm. You don't know since the bars peak out. I know I measured it. 1 dot is closer to -120 dBm.
Anandtech's new bars agrees with my findings.
The point is that two users each with 5 dots may vastly be consuming different battery drains. And certainly someone at 3-4 is consuming more battery. The difference for me at home and in the city can be an hour or more or less usage time.

There is nothing wrong, and in fact it is great. This is a 6, not a 6+
Photo stream is on, and mail is fetching and pushing in the background. This is normal.
21 hours of standby, and little usage shows that the iOS is not drawing my battery on its own. With normal usage, with my habits, I'll get 8 hours of usage. In a stronger signal area, it might go to 9-10. No audio being used.

I'm experiencing the same difference.
Going from Rome where I work and live, to Milan, my hometown, I can gain more than an hour in usage time.
In Rome I have 3-4 dots, while in Milan I have 5 most of the time.

Blimey. I barely get 10 hours on my 6+ unless cell and WiFi signals are strong. Otherwise I see 11 hours. It's strange that some people get great battery life from their 4.7" and others only see 6 hours.

Sounds about right.
----------
Depends on so many factors. Especially signal strength and screens on time.
Now that I'm using the phone more, time is ticking. Spent about an hour plus listening to NPR wifi radio and 15 min of an audio book. In this case background activity means I'm using wifi radio but the screen is off, phone locked
Still on my way to 8+ hours. Standby time is incredible. That happens a lot when my phone is in a pouch. I check it less often, so the screen is not on.

Yes but I see no reason why Apple would have reverted back to the older behaviour in subsequent updates. Using a linear scale gives a more accurate reading.
I have 8.1.2 on my 6 Plus and I couldn't figure out why my battery was draining. Something I noticed was that before I added Apple Pay, I would go from 100% to 99% in 45 minutes. But after adding Apple Pay, I noticed that there were some inconsistencies because sometimes I would go from 100% to 99% in 30 minutes or less than 30 minutes.
Then one thing I noticed was that when I went to Privacy > Location services, I noticed location service for passbook was turned on. Not sure if this was the reason but I have turned it off and will fully charge it over night and will find out tomorrow morning. I hope Apple way works without location service being turned on for passbook.

So i have just received my iPhone 6, over a week back. Initially i restored from my iphone 5 backup and all was ok except for the constant "Motion Calibration" using my location.
So I restored as new and then the Motion Calibration(MC) was not using battery continously for a day or so. It was turning on and off at times.
However, aftter couple days, its been using it constantly once again.
Do you all have this issue. There is this thread on Apple as well with the same issue. Also, I am sure it affects the battery life as well as it is constantly keeping the Location on.

And we are back at random shutdowns when the battery is 10%+.
Lots of my facebook friends have the same problem with the 5s!
Yesterday I had 19% and 2 minutes later when I checked he was shutdown and could not be started again! When I charge the iphone it obviously starts at 18%... annoying!

As I suggested elsewhere, have your battery checked because it could be an hardware problem. We saw many iPhone 5 users complaining about that after iOS 7 release, but at the end in most of the cases it was a defective battery.
If after a calibration the issue persists, it probably is an hardware issue.
