Q: iPhone 4s Battery Life?

How can i know if my problem with battery is software or not??

It is irrelevant. The question is more "can I solve my problem or not". If you methodically try the solutions provided by those guys, and have gone through many charge cycles, and you cannot solve the issue, then go to your seller and ask for support in the form of replacement or such. I think that's the way to go...

If its software problem i can wait,but if is not i ll change the phone to apple store..(monday i will go for make sure that all hardware its ok,they have some program for testing..)

The 5.01 update completely solved my issues.

I never reset my settings, never did a full restore - just did the 5.01 update from the iPhone menu.

Wifi, iCloud and some notifications are always on.

My last charge gave me 4.5 hours usage and almost 4 day standby. I know I'm a light user compared to most, but I have no complaints here!

P.S. I noticed a few posts people were complaining about iCloud being the issue. It clearly states iCloud is only active when the phone is in 'lock' mode, wifi is on and *plugged in*.

Oh, I understand, you mean wait for a software update. I wouldn't count on that, even though no one really knows. It wouldn't be surprising if a very small fraction of the handsets do have hardware issues, as this is normal with any product. I guess at the store they can tell. Maybe also have them try a new sim card and there was also discussions about the Sirii IR thingy some pages ago which you can look into, and which I forgot to include in my summary.

Good luck!

Thanx for this feedback! Always nice to know my work benefits at least some out there.....

Thanks:)so i don t think is hardware problem,now i m on 7%but i dont remember when i restore in dfu mode at 13:00 the % of battery..:)maybe 70/80%..

Kloposso,

This is highly likely NOT a hardware problem. Don't go and return your phone because it will likely not solve anything.

All my tests show it is a software/configuration problem, I can show you two configurations of the same phone, one showing the problem and the other not showing it. With the problem, the battery drainage during idling is about 30 percent in 10 hours ( so about 3 percent per hour ) and the other configuration without the problem shows about 7 percent battery drainage in 10 hours ( that's less than 1 percent/hour )

Have faith.

Regards.

That's exactly what I'm investigating :

What it clearly states is not what I'm seeing : iCloud IS active when not in 'lock' mode and IS communicating over wifi when NOT plugged in.

Regards.

Yes i know,but this is the second iphone 4s..with the first the situation was not lIke this..ind when i take this the situation was better..now the battery when i use go down of 1%every 3/4minutes..and now im on 3%..but im really using the phone(look up i was on 7%)..sorry if i cant explain very well but im the classic bad italian with his horrible english:(

I have been having the same battery nightmares as everyone else on the 4S. Happened to disable iMessage for an unrelated reason and the battery life sorted itself out... Now back to what I had with my 4 on ios4.x.

Might be a fluke, but happy now either way.

You too have to be commended for helping out users. Unfortunately, you suffer from the same bias as davidch. If someone implements your steps or basically all the intelligent tips in the forum and can't solve his issue, after many resets and charging cycles, then he SHOULD return his phone. As there are always hardware issues with a very limited number of devices - at least that can be checked at the store, as the user cannot check his battery for instance as Apple decided to not make it serviceable. It may also be his hardware is fine but none of the steps work for him. But a problem is a problem irrespective of cause, and the vendor should solve it after the user's best efforts.

Faith? This is not religion, this is consumer electronics with a sale and consideration. The seller should be held up on his bargain.

After all, conceptually, all you guys are doing is sanitizing harware/software elements with reinitializing - something Apple should have implemented directly within their 5.0.1 patching process. Furthermore Apple should "burn in" the batteries directly at the factory to save time for its users. There is no magic.

This is only for backups with iCloud.   Other services will use push notifications or detect it's on wifi and sync. For instance, Photstream, if it has updates, will upload as soon as it detects wifi regardless of being plugged in.   Document sync will also happen on wifi.

In fact, I found on my phone a corrupt Apple Movie Trailers app document that was stored in iCloud and for some reason also sync'd with my Mac.   The bug was that the file was corrupt and anytime I was on wifi at home with the mac, the mac would try to sync with the file on the phone and in cloud and error.  I found these connections looking at netstat, correlating some process id's and finding another process log that showed the constant reties to the phone from the Mac.   This occured every 3 minutes while powered on and also occured in standby as soon as a notification woke the phone.  It also would auto wake the mac whenver the phone turned on and try to sync since I use wake on demand for iTunes homesharing etc.  This is actually what got me to start looking at the logs and finding the problem.   Once I deleted the app, the problem went away.  The document would not delete even using the Mac's iCloud  system prefence settings.  Reseting iCloud settings probably accomplishesthe same thing if there some 'hidden' type syncing issues or corruption.   I went from getting around 4-8 hrs of usage and a day of standby to 6-9 hrs of usage and 2-3 days of standby.  I have full iCloud options, exchange gmail, a lot of notifications, and all standard location options on.

I still use iCloud and iTunes Match.  Really these are 1.0 versions and there are bound to be issues. Hopefully we'll see some more tweaks and everyone will get some more stability to their battery life.   I think what's frustrating is it is hard in iOS to see what is using battery so unless we stumbles on tweaking settings or actually logs in my case, we're sort of all stumbling around.  I think everyone's phone is sightly different because of the multitued of settings and apps.

Sanity checking. This is where Apple failed with their release in my opinion. Lots of work to be done there. As it stands, they almost made a proof of concept that malformed data within cloud/restore can DoS their iDevices through battery drain. Epic.

Although your stuff has helped quite a few users, be real. The standby spec is 200hrs so that means 0.5% per hour (100%/200) - bare - so the drain will never go under that, even less so with additionnal polling etc. I have never seen anyone with <0.5% drain per hour. I mean, have you ever seen that?

i have seen that consistently now on standby on mine and other users iPhones after going through my process. i have not used my phone much at all today (off work and doing other stuff around the house).  It has just been sitting mostly all day.  The current stats are:

97% Battery, Usage: 28 min, Standby 7 hrs 58 min.  So it roughly used 3% at almost exactly 8 hrs (.03/8 = 0.0046875 or .47% an hr).  again, that is almost entirely on standby as i referred to in the post

yes, i do recommend that user take into apple after the procedure due to a likely hardware/battery issue, if it does not work...

In my experience this improves the Standby battery drain issue significantly in most cases.  It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple.  Good Luck!

neither myself, buxbuster or anyone else that is helping out is "bias",  we are just trying to help users solve the issue instead of just ranting about it or requiring the user to take it back.  iPhone issues have occured with every release (2G -> connectitvity, 3G -> connectivity and battery issues, 3GS -> yellow tint screens and battery issues, 4 -> you ever heard of antennagate?)... and we somehow made through.  it most these recent cases, his or my rememdies do fix the issue for a lot of people.  at the end of day, that is what these forums are for, not your and numerous others grumbling about apple.
