Battery, 10% per hour?

I have an iphone 4, have had it since about a month after they came out. I was always unimpressed with the battery life but now it's gotten worse. Now, I know I sit here and use it frequently, but 10% of battery life per hour seems a little extreme. And that's just if I let it sit there. If I'm using it heavily, then it's dead within 4-5 hours. By heavily I mean manually checking email (two accounts, yahoo and gmail), checking facebook, a couple apps, I make a phone call about once a month, not kidding there. I get phone calls throughout the day but I never answer them, let them go to voicemail. I take pictures, probably one a day I'd say on average. When my son plays a game or two, angry birds and cut the rope, for like 20-30 minutes, I've seen the battery drop like 15% in that time span. I keep the brightness on full. I hate how dim it looks otherwise. I use wi-fi at home, bluetooth is off. The battery has gone down by 3% just in the time it took to write this so far (10 minutes maybe?) and that's only because the phone has been active as I received a couple text messages.
I charge it to full every night and lately I've had to recharge in the middle of the day as well.
I have read many threads here and on other sites that say to recreate Exchange email accounts (I don't have any) restore as a new phone, and complete a full chartge cycle by letting the phone completely drain and then recharge it without interruption. I've done all these things and yet the battery life remains terrible.
I see some comments from people saying they can go 2 to 3 days without having to recharge and it makes me wonder if they keep their phone in airplane mode lol. I just think it's time for me to replace the battery, but before I do I wanted to check one more time to see if someone had any magic cures they could share. Oh I'm on the latest firmware and on AT&T.
Thanks.

Update, I've noticed that my usage and standby times show the same amount, currently at 2 hours and 43 minutes, my battery is now down to 78% and I have not used my phone much at all today, just letting it sit there. I have killed everything that was running in the background and still, the usage shows the same amount for standby and usage times. I do not believe this is a hardware issue, it is more likely a software issue.
There is clearly something wrong. Note, however, that it is impossible to kill everything running in background. Killing apps in the Quick Launch ribbon does not necessarily kill the background process (it does for 3rd party apps, but not built in apps, which relaunch their background processes immediately). Some app queued data to be sent, and the send failed, but the app or the lower levels of the network protocol keeps trying to send anyway.
As you mentioned, the most common app that can do this is the email app, especially with if you have an Exchange account, but any push account can do it (whether push is on or off). So can Ping, the Apple store apps and Game Center. And ANY app that sends data can queue it.

What is the calculations to see the % of battery drain per hour?

I was just wondering if there is a specific way to find out how much %/hour the battery is using? combining the the standy time/usuage? Thanks.

You can measure it. Go to Settings > General > Usage > Battery Percentage and turn it "On".
Then check it out every hour and keep track.

IP4S Battery Drain Was 8% hour. Restored As NEW PHONE Via iTunes Battery Drain Now 1% per hour!

RE: iPhone 4S rapid battery drain out-of-the-box.
I had been experiencing a battery drain of 8% per hour.
Apple's software update did not make it better!
I then restored my iPhone 4S as a NEW phone and now my battery is draining at 1% per hour with all settings at maximum for battery drain.
Apple could have done more to make millions of customers happier customers.

Thanks for sharing. Restoring the phone first from backup then as new is one of the standard troubleshooting steps outlined in the User Guide. Too bad more people like you don't realize this.

Peak No. Of Requests/ Per Hour in BW

Suppose my cube gives performance of 5 Sec for a given query to run.
How does one estimate, assuming Bandwidth can scaleup, at what no. of peak requests (in per Hour or Per minute or Per sec) would the BW server show considerable performance degradation in terms of longer query runtime.
How much of this can be addressed by caching? Are there situations when Cache would get corruped due to high number of request, each potentially with differnt set of variable inputs?

WiFi doesn't drain anything in Sleep mode because WiFi is turned off in sleep mode. Something else is causing the heavy battery drain.
As you said you don't have any email accounts it isn't email. Safari can drain the battery if left on a page that automatically refreshes.
Location Services can drain the battery - if you see an arrow in the top bar near the right then there is an app running in background and using location services.
Game Center can drain the battery even when it is closed.
Streaming apps, social networking apps (facebook, yahoo, skype, etc) can also drain the battery in sleep mode.

Lumia 1520 Discharges 18% per hour in standby with...

When we first got 1520 6 weeks ago, battery performance was pretty good but now
1. Lumia 1520 Discharges 18% per hour in standby with no background tasks runinng
2. Took 1520 back to Microsoft Store and have now had 2 replacements and all behave the same
Discharge between 18 and 22% per hour - no data, no tasks running and phone not even being used

Thanks for those who replied - so the issue is now basically solved
What we did was :
1. Reset phone
2. Setup phone as a new phone and did not download any of our purchased apps from Microsoft Store
3. Voila - battery now behaves perfectly - discharge rate is 2.53% per hour - down from over 18%
4. So although - we never had any apps runnig when the battery was discharging at 18% - we surmise that some app was behaving badly
5. Now all we need to do is to find out which app was the culprit
Thanks again to forum members for their input

T61 charging very slow, 1% per hour.

I thought that my T61 was not charging, but it seems like it just charges very slow. Approximately 1 % per hour. Any ideas?

Your 90 w adapter is broken, the 65 w is not suitable for your machine, if you have the nvidia GPU. There is no sufficient power to charge your battery from the 65 w adapter.

IPad 2 Won't Connect into iTunes, and Charges at About 1% per Hour on Charger or iTunes.

Hi there,
The title says it all really.
When I connect iPad 2 to iTunes it doesn't connect - it does through wifi however.
When connected to either iTunes or charger it doesn't say it's charging however it will if wifi etc. are off at about 1% or so per hour.
Yes! I have tried restarting both the computer and the ipad, different outlets, charges, computers and leads, etc., etc., etc.
Maybe someone has some ideas?
Thanks,
Jim.

iPad Charging
"The fastest way to charge your iPad is with the included 10W USB Power Adapter.
iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter.
When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it's in sleep mode.
Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain."

Please help, how to send mails faster / send more mails per hour

hello,
in my application i am using mail sender class i have created to send mail to the users to participate in a survey. following is the code for it. i would like to know if there is anything wrong in it coz it takes to much time to send the mails it is taking 2 minustes to send 6 mails i.e 360 mails per hour only.

Lots of variables here....Also my maths says only 180 per hour.... i.e. three a minute.
1) you are using a database to get info from. What is the average response time of the DB server? Looks like you are doing one SQL then reading the result table but does the initial SQL take a while?
2) how much data are you passing on to the SMTP server and how fast/slow is the link to that SMTP server? Work out the absolute max amount of data you can transfer over the link then get your average message size and work out a VERY theoretical Max number of messages a minute. Note that real life might approach 80% of this taking TCP/IP and SMTP overheads into account.
3) What sort of load is the SMTP server under? If it's busy you will be only getting a fraction of whatever bandwidth is available. Depending on its design it may be trying to deliver the first message you sent it while you are still pumping more messages down to it. SMTP servers may limit the number of connections per minute from another machine in order to defeat a denial of service attack. Your code makes a connection per email so this may have relevence here.
4) Raw horsepower always helps. When I write stuff to do things like this there is no nice GUI screen etc. Just basic Java that if it has to will write a log if something goes wrong. Maybe just maybe a counter on STD out to show it is still actually doing something. Keep the number of classes used down to the bare minimum. In the old days we used to spend days paring code to the bone - a skill somewhat lost these days.
Hope this gives you some help in finding the bottleneck.
Cheers,

How much data does the apple maps app use per hour ?

hello,
i would like to know, if somebody could give me a rough number of how much the Apple Maps app uses per hour for navigation ?

Apple's Maps app uses vector graphics, so it doesn't have to download data everytime your view changes, & also has an offline mode...you can download quite a large area over WiFi & then use this cache to navigate.
So, I really wouldn't worry too much about its data usage. Most tests I've read indicate it uses about 80% less data than Google Maps.

12GB per hour of HD footage instead of 29GB?

Hi,
I recently switched over to HD camera (Sony HDR-HC1E). This is a DV tape cam.
Im editing in imovie 6.0.4.
I always back up my files by exporting via imovie "full quality" when i used to do this with SD content i would get a DV file as result, now on HD i get a .mov file.
I used to get a 12GB file for a 60min movie. Now with HD i am getting 29GB per hour.
I hear other people talking about 12GB per hour for HD content.
Can anyone please tell me how this is possible?
I am going through external hard drives at lightning speed!
Thanks
Dave

Hi Dave
There's actually a big difference between a DV stream (whether recorded to tape or file) and a .mov file.
DV or HDV footage is recorded at 25Mbps - megabits per second. This translates to 90000Mb per hour, divide by 8 to convert bits to bytes, and you get 11.2GB/hour. That's constant, whether on the tape or saved as a DV file. Note that DV is pretty compressed.
Now, when iMovie (or any other video conversion program) saves a .mov file, it's no longer a DV stream. It can be any of the codecs (video formats) that your program supports, and there are a wide range of codecs for both SD and HD. These different codecs will use different file sizes depending on their level of compression. (Just like mp3, a compressed audio codec, vs AIFF, an uncompressed codec.)
You can choose to optimize video on import or choose a smaller format on export (large, rather than full size) which will reduce the frame size of your footage, which may be a good solution for you, depending on what you ultimately plan to do with the material. (Edit: actually, not with iMovie 6 - thanks, Karsten Newer versions of iMovie will help you there. )

What setting is 'DVD quality' widescreen - ie about 3gb per hour?

I have videod (isn't that a such a quaint 20th century word for the podcast age?) a conference and I want to archive the footage to store on a DVD for later reediting.
The "full quality" setting is massive, I only have 90 mins, but a 20 min clip takes up over 10Gb
The 'CD-rom quality' is just not not dvd quality.
(I am using iMovie 06 btw, i will move onto 08 when it is finished)
Ideally, I would just burn the whole lot raw with iDVD and import it again if i need to reedit - but (for copyright as opposed to technical reasons i suppose) we can't just put a dvd in the slot and rip it like we can an audio cd in iTunes. I have tried the workarounds - but none of them worked for me.
Anyway, I digress: What setting is 'DVD quality' widescreen - ie about 3gb per hour?

Hi there.
*Keep the quality*
0nce you have compressed data - you can't get the original quality back - so store as full quality as possible - and in several formats so there is always a backup.
Media
data cds don't hold that much - 700mb - so forget about them for quality productions and archiving
dvd-roms hold much more - 4,700mb (you can get dual layer ones that double it)
*'share' settings*
Now, you have 2 options for saving the movie;
1. as a file on a DVD-Rom (a compact .mov or a massive.dv)
2. as a proper playable DVD (iDVD)
If the "full quality" iM setting is too big a file for a dvd-rom (and you will be lucky to get 10 mins of footage in 4.7gb), then you could 'iDVD' it and that way you will get a good quality movie up to nearly 2 hours on a disc disc that can be played on most machines (and could even be ripped back into an editable form using third party software)
Alternatively, save it using 'expert settings' listed above and you will probably get good enough results for a longer film without having to burn it as a playable (but uneditable) dvd.
Bear in mind that unless you are using a pro camera, you may not notice the much difference with the higher settings.
Good luck - seeing your work on the big screen is a blast!

Rows per hour

Dear All,
I have a table with 2 rows and one has varchar type data and the other is the time stamp (04/02/2013 19:44:40).
Now I want to write a query to count number of rows per hour in the table with date ...strcutre is as follows :
ddata varchar2(20)
ddate date with timestamp ;
Require the output as follows :
March 28th 12 AM - 20
March 28th 1 AM - 40
March 28th 2 AM - 40
where March 28th 12 AM is the date with time
and 20 - number of rows in that date and in that hour..
Please advise..

Whenever you have a problem, post CREATE TABLE and INSERT statements for a little sample data, and the results you want from that data.
>

ddate date with timestamp ;What is this? DATE and TIMESTAMP are 2 different datatypes.
If ddate is a DATE, then it is not a TIMESTAMP.
If ddate is a TIMESTAMP, then it is not a DATE.
Require the output as follows :
March 28th 12 AM - 20
March 28th 1 AM - 40
March 28th 2 AM - 40
where March 28th 12 AM is the date with time
and 20 - number of rows in that date and in that hour..
Please advise..Here's one way:
SELECT    TRUNC (ddate, 'HH')           AS hour
,       COUNT (*)                AS cnt
FROM       table_x
GROUP BY TRUNC (ddate, 'HH')
ORDER BY TRUNC (ddate, 'HH')     -- Or hour
;TRUNC (ddate) will return a DATE, regardless of whether ddate is a DATE or a TIMESTAMP.

How much is a GRC consultant paid per hour?

I know that in USA, for FICO consultants the rate per hour is in the range of 100 -150 dollars per hour. Will a GRC consultant get more than this or less?
There is a qualification called CISA. Is this GRC anyway realted to this?
Is a GRC consultant involved in SOC compliance?What does he exactly do?
