I hear what you are saying, but I'm not sure I understand what you are trying to prove here. A 10% battery drop, over 22 hours with CELLULAR ON, is totally acceptable, even if nothing else is happening. Sounds like you're turning your expensive purchase into a knick-knack for no valid reason?
Here is the point. Even though the phone is within the standby specs, it still used that data and 38 min of time to do nothing of use to me. I can only imagine what it would use if I didn't have such a restricted setup. If the phone didn't work so hard in standby, it would add to the usage time about 45 min in one day.
I'm suggesting you would need to compare this against some OTHER smartphone, to have a valid comparison. Right now, you are comparing it to nothing. Your thinking is that this is abnormal, while my thinking is that it is totally normal. The battery results are what is important here. A 10% drop over 22+ hours is very much acceptable......
@Bellatone - Apple stock droped 10% due to the way they recognize sales, Wallstreet wanted to see sales blow the iP4 out of the water and the markets up'd the stock value in antipication of it. What the genius elite at Wallstreet didnt know is the high pre order volume of phones does NOT equate to the the sales $ figure at release due to Apple only billing you when they actually ship the handset ergo supply chain lag of 3-4 weeks was instrumental in stripping down the sales figure at release. The lagging order to sales figure will eventually catch up with handsets eventually shipping soon after order, but to the markets, this was unacceptable and thus the "quick money" left Apple stock with the c.10% decline in overall value. In short, this was the treadmill effect by Wallstreet in play in combination with a successful marketing hype campaign by Apple, and rather effective it was too. So all said, the 10% drop has nothing to do with battery issues.
@Jameson - I agree 100% with your approch on breaking in the new Iphone and how to care for the battery. I intend to do this when I receive it early November. I shall report back on how I get on.
This will happen.. as some other members stated a few million pages back in this thread, its something that happened with Iphone 4 and was resolved with a firmware upgrade. Same will apply when we see iOS6.01 coming our way with Im sure the customary keynote speech to explain the ins and outs of the problem in broadstrokes.
I am confident that this will resolve for a few reasons;
1. Battery power is relatively the same for Iphone 4 and Iphone 5
2. Power management enhancement in Iphone 5 is real as it delivers increased functionality at same hardpower power specs for the battery. Thing is, some of these enchancements are new to Apple like iCloud syncing over cellular which leads me to the 3rd point
3. Iphone 5 "uses" more cellular then Iphone 4 and the power management associated with signal usage mainly in cellular is not being helped by LTE network construction/carrier permissions/coverage for some networks especially when they piggy back of others/etc. The increase in background usage of cellular needs to be refined in the next upgrade of iOS6 with better, more effective protocols for power usage in the identified signal scenarios.
I am confident it will be done and Apple will resolve these issues in a firmware upgrade to iOS6.01. For my part, I will set up Icloud synch and email push/pull at reasonable intervals completing my set up in my Iphone 5 to be seeing if my power usage can be maximised under the conditions I find myself in here. I will report on my usage and set up when available early November.
Hi Handsfull, as you have requested i took a scrren shot just under an hour ago of my results since the last picture I uploaded.
As you can see the battery is working great, the only thing I have noticed is that when i have no signal the battery decreases a lot faster
Can you confirm you're not using 3G or LTE? Totally agree with your last sentence, especially when searching for new networks.
I'm now at 3% with 13 hrs 50 mins "usage" and 1 day 9 hrs standby. Admittedly I've had cellular data (3G) turned off for most of that time as I've been in wi-fi areas except for approx 3 of the 33 hours. Time to charge it up now!
My network is 3G only not even 2G services are supported
I would say that during the past 2 days I have used 60% wifi and 40% 3G. Again when using the phone the screen was On and music has been playing whilst I have used it.
I have not let applications run in the background btw
I thought you reverted back to the original carrier settings which let you use 2G...?
When you say "I have not let applications run in the background btw" do you mean you double-clicked and killed them each time you closed them?
I have moved my 2G sim to my 4S as I need better coverage and faster data on my iPhone 5.
So my T-Mobile/EE Sim which is 2G/3G/Wifi depending what I select, on the 4S is running fine
and Network 3 which I have running in my iPhone 5 is 3G/Wifi only.
Sorry for the confusion on my Sim selections, I thought you would have noticed from the pictures.
And yes I always close the apps after I have finished using them (seeing as Notifications will alert me when I need the app again, I dont see any reason on leaving them open and wasting ram, when I can use it for other features.
SOMETHING TO TRY: I had this problem big time (on an iphone 4; total drain in about 4 hours ever since updating to ios6), but yesterday evening my battery was at 81% and this morning it was still at 81%, with all but one thing turned back on. In fact the battery performance was so good I had to watch a long video to drain the battery and convince myself the indicator wasn't stuck.
What worked for me (thanks to GrahamE over on another thread) was turning off email push. I found that with it turned on, the phone was transferring about 5MB per hour *via 3G*, even though I was on a solid wi-fi connection. Turning off cellular data stopped the battery from melting my phone and turning it back on again made the problem come back. I'm in a lousy reception area, so my cellular radio has to work full power and drains a lot of current. It shouldn't have been doing anything at all when I was on wi-fi, but the culprit seems to be email push.
For me, anyway. Unless the problem is being resolved behind the scenes and pushed out over the air (firmware u/g, say) and my fevered fiddling had nothing to do with it!
But anyway, I ate through over 200MB of cellular data while sitting in my apartment, right next to my wi-fi router, and that constant use of the cell radio was what was killing my battery. Totally working now. Batt still at 80%.
P.S. Use DataWiz to see how much data is going over wi-fi and cellular while you turn things on and off.
