Q: iPhone 4s Battery Life?

Pozdrav,

BTW iz Trogira sam.

Meni se čini da je to problem, kao da stalno "radi" i nikako u standby modu.

Tražio sam okolo rješenje u vezi tog problema i negdje sam naletio to.

Ja sam izbrisao mail jer sam imao samo jedan, a isprobavao sam sve i svašta

samo da dođem do rješenja.

Ja bi ti predložio da probaš resetirat network settings, reboot-at.

Onda bi ti trebale biti crtice na Usage i Standby time, dok ga ne napuniš na 100%.

Poslije toga pogledaj da li će ti opet biti identično, nadam se da neće...

Ako baš imaš dosta email računa onda probaj bez brisanja, ja sumnjam da je to išta utjecalo

ali sam pratio druge tako da san napravio sve šta su predložili.

Ima dosta materijala o ovom problemu po internetu(mislim na identičan Usage i Standby) i mislim

da ako to popraviš da pokazuje kako treba onda bi ti trebala baterija trajat puuuuno duže.

P.S. I nemoj zaboravit postavit u Settings -> Mail, Contacts, Calendars -> Fetch new data -> Advanced -> Manual

--------------------------------------

"Since I have multiple email accounts they was allllll set to fetch. I had fetch new data and push set to off but when I went to advanced settings I noticed that each email account was set to fetch. I switched them all to manual and bingo. Strange I know but now my usage an standby time is no longer equal.

So if anyone is having poor battery performance I would suggest looking into this."

Good luck!

Is trogira? Nemoj mi rec da si jedno vrime zivija na Hvaru?

Nisam, samo Trogir i Split dok sam studira

My iPhone 4S has a serial number starting with DN.

I took of the sim card at 5:28 as I always thought the battery drainage was sim-related. 15 minutes later (5:43), I lose 1%. I'll keep you up with my stats and see where this goes.

14 minutes later, I loose 1% with no sim card inside and on standby. Looks like it really is a hardware issue. I'll make sure I change it to an iPhone that starts with serial number C3. I'm not satisfied at all with this.

Try this yourself: take out the sim card and leave it on standby with all apps not running in the background. If the battery drains, then it is probably a hardware issue. 

For me a big difference when in the Netherlands using T-Mobile or KPN as a provider.

With T-Mobile we're loosing 15-20% overnight with a fully charged battery. With KPN only 3%.

The question what is the network of T-Mobile doing? I'm glad we are not using T-Mobile anymore.

You are one of the few people on here who has been able to get rid of the usage and standby times being the same, or nearly the same.  I hope your procedure works for others.

Guys I have seen this posted in various places so apparently help is forth coming. (why the network reset seems to help I suspect)

"The phantom usage is seemingly down to a bug in the baseband that keeps it from closing network connections properly. The new baseband in iOS 5.1 Beta 3 seems to have fixed this bug."

Have seen  other posts that 5.1 beta 3 has made significant progress to the battery woes.

[Disclaimer] I am nor a developer nor do I have 5.1 installed. This is information I have read in various other places.

Just to be sure, do the network reset, and the phone hard restart to make sure any running task gets terminated.

To be honest, for me the usage meter is not correct anyway. I can talk on the phone  for a while and none of that usage actually shows up. One day (slow day) I was on phone for 60 minutes, checked email a few times sent a few texts and downloaded an app and fooled with it a bit and my usage reported 30 minutes. I knew that I had at least been on phone calls longer than that so looked at call logs.  I dont have battrey problems BTW since 5.0.1. Anyway the point is the meter doesnt seem to be accurate and possibly both ways. Maybe reporting usage when there is none and not reporting usage when there is. From last post the phantom usage has seemingly been addressed in 5.1 beta 3. Fingers crossed for you guys.

AliAr - i'm already doing that and guess what?

Without SIM card i already have 3days and 14hours with 50% left.

With SIM, the phone lasted 1day and 6 hours with very light usage (10minutes of calls, 4 text messages, 5minutes surfing the web - only time the cellular data was on- with all other settings turned OFF the whole time). Also a DN...

My question is: if i send my iPhone to repair, how will the techs know what the problem is?

The phone is going without the SIM Card...once in their hands, without my SIM Card, the phone will behave like it's doing now: Excellent!

If i'm lucky (usually i'm not!!), the phone will not present the same behaviour when they put their SIM Card to run some tests, and start behaving like it does with my SIM Card...but what if it doesn't???

What if the problem is caused by the Carrier? I already called my service provider in Portugal (TMN) that said to me, after checking network configuration, that there is nothing wrong with the SIM that could generate the draining problem...

Can you see my dilema??

I'm waiting for the 5.1 before sending it, but i'm pretty sure that it's not going to solve the issue...i'm kind of like the fool in the middle of the bridge: "Which side will i go, left or right??? Or should i stay put???"

Apple has been putting out a new phone every 12 to 16 months

I made the network reset and hard reset about 30 minutes to 1 hour before removing the sim. Seems like nothing will actually work.
