Q: iPhone 4s Battery Life?

aaaand, this is the kind of stuff that cracks me up. Random people on here like jorgejr, who have never even taken a look or worked on anything pertaining to phone development, somehow think that they are going to be the savior of all with regards to iPhone battery drain issues.

I said it back in the early pages of this topic and was ripped on & called names, that NOBODY can fix it except Apple, and having to turn one's phone into a useless brick is NOT a fix, and that we'd still be here until Apple releases a fix... I was called names and attacked for that too.

And here we still sit. But watch, those useless scrubs who attacked me then will attack me again. Way too funny!

I'm from the Philippines. I bought my iPhone 4S last Dec 17 (Around 20:00) (So I'm one day ahead of you guys. As of now its Dec 19 at 22:30). I did a 'rough' charging to it because as soon as I went home, I updated my firmware 9A406. So when it was plugged to the computer it charged to 100%. Didn't got a chance to drain it then full charge it.

Do you guys think I have the battery issue? Is this usage acceptable?

I made a total of 1hour phone call and usage mostly with the Internet, texting, playing with Siri and some apps/games. No music played yet / light camera use.

Model: A1387

Serial: C38

Settings:

Wifi turned on only when in need.

Notifications on Manually.

Notifications Center only what is needed. (Phone, Messages, Calendar, Reminders, Facebook, Twitter)

Location Services OFF

Brightness on Auto-Brightness but is set to 50% - 60%

Siri turned ON, Raise to Speak to OFF

Cellular Data is OFF

Bluetooth is OFF

Auto-Lock 1 Minute

Restrictions OFF

1 Yahoo! Mail set to Manual.

i have read also some comments , that we should turn everythins off to reduce the Battery drain !!!!!!!!!!!!!!!!

like Notifications, Location service , Time zone settings , and 3G ... etc.....

then if i turn this all things and options off ,,,, can Apple tell me why then i have bought and choosed the iphone???? !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ofcourse everybody pay for some services like 3G forexample , so for what i will pay if i must turn it off to solve the Apple problem !!!!    and by the way after turning this all off ,,,, the Battery life seems to be the same

therefore, Apple MUST really find and fix and solve finally the Battery issue within coming update !! hopefullyyyyyyyyyyyyyyyyyyyyyyyyy

thanks

Thanks, jorgejr! The exchange-server tip did it for me!

Since I bought my 4s I've been at 50% battery after 7-8 hours with moderate use (some facebook, reading a bit of news, some e-mail, wifi on, GPS allowed for all apps except facebook and weather. Siri is deactivated. All system location services off except compass and search for mobile network). It's been useable, but not impressive.

After setting the Exchange server and iCloud (which I only use for fotostream) to update contacts and calendar (both Google) every 15 minutes instead of push, I'm getting 75% after 10 hours with same use as above. And that's with the Gmail and Facebook app still using push.

Guys, you need to try this... at least he fixed it for me.

I'm not using exchange on my phone. I have never been close to your numbers, My phone is now on 45% with 3 hours 46 minutes use(phone calls, web surfing, imessage), and 13 hours and 50 minutes standby

How do you charge so that it won't turn on at 4%? Mine does that. How did Simeon did it? Few pages back. (Page 500, 2nd post)

Also, I noticed that the charger (the one you plug to the outlet, charges very fast. LOL.)

So an update to my last post a few pages back, turns out it actually wasn't Siri that caused my "phantom usage" (my usage and standby time were showing the same time) and caused my battery to drain 27% overnight. It was safari, I had a page left open and apparently safari kept it running in the background. As soon as I closed the page and then closed safari in the multitask bar, my usage and standby began increasing normally. Throughout the day and overnight I'll monitor and see if my battery is any better, hopefully it doesn't drain overnight again and goes back to normal. If any of you are having problems with the usage/standby showing the same time, see if you have any safari pages open and close them, that may solve the problem.

Dear;

Upon investigating the battery issue, i think I have narrowed it down towards the wireless chip software and the protocol of the wireless router.

If you use a [b/g] capable wireless device the battery gets drained alot, but when using a wireless device capable of [n] the battery gets normal behaviour back.

I think Apple engineers should take a look at the wifi chip software to figure out why this drains on b/g capable devices.

Make sure you shut also settings like bluetooth, traffic, ping, Push off.

Please report back to Apple if succesfull.

Hi All,

Ive updated my software on the 4S to the latest build and power-cycled the device yesterday, today the device seems to be doing better but i have everythine useful turned off. Birghtness on manual dimm'd all the time, wifi off, location services off, no notifications.

This is my current stats -

Can anyone tell me if the above screenshot looks normal and like what i should be getting?

Thanks!

it doesnt

i have here since yesterday 95% battery and 30 mins usage{internet and phone} with ~16hrs standby

this is normal if you only turn on the feature you need

in the house if i wanted to use the internet

becouse i realise it will use the battery

i would normaly add a cable 

but i have a laptop so depend on wifi zone and btfone sites

for the iphone when not at home

i would expect to have a 'decent usage'

so till it goes to 20% ill chart my iphone usage as just this and not use my home wifi connection

i like the post above about b,g and n type wifi

i have both types  the main isp one  is n and the slave wifi is a b.g only

so lets see  but man 5% battery for 20mins internet and about 5 short calls to the family

and some 16hrs overnight etc is aok

I don't think you have it quite right.   The problem, IMO, is more on how iOS5 manages cellular data connections, not wireless.   When I am connected to wifi (wireless N at home and wireless G in the office), my battery life is perfectly acceptable, with less than 1%/hr drain.   As soon as I lose a wifi connection, my phone starts to drain at 5% - 6% per hour on standby, faster when in use.   I leave the house at 100% after an hour off the charger.   After my one hour commute, I arrive at the office at 94-95%.    At noon, 5 hours later, I'm still at 91-93%.   An hour out for lunch, with some moderate use, Icome back at 81-83%.   When I leave the office, 3-4 hours later, I'm still at 79-80%.   By the time I arrive home after the hour commute, I'm at 73-75%.

On Saturday, we were at a relatives home with no wifi and I lost 60% of my charge over 8 hours, with light usage.   Cellular signal was marginal, which I'm guessing made the problem worse!

If I do use the phone often while in the office, the numbers will be lower, but relatively the same drain rates.   I have EVERYTHING on except Siri lift to activate.   I'm convinced that this is a cellular data management issue, probably caused by the iOS5 software which manages the dual antennas in the 4s.   It'll be interesting to see if APPLE can design a fix that will maintain the ability to deal with the new antenna configuration, but fix the draining issue.

Well I bought 3 Iphone 4s and all except one has horrable battery life. From all my research I see that the usage and standby are going at the same rate. My other 2 phones will be example 5minutes usage 1 hour standby, with everything on, and get good results on the battery meter. My other is 1hr standby and 1hr usage, and get horrable results on the battery.  I have talked with apple and tech support they are not so helpful at to why my phone does this, my friend who is a computer genius says that its not the software its the hardware not working correctly, I guess trade it in and see what another one does. Hope this helps seems that most phones work like they should but I wonder after the year is up will my others start having this problem.

Just to confirm, my problem also appears to have been caused by a particular brand of wifi router. I was getting bad battery drain at my office with the usage stat always very similar to the standby stat. I tried the second wireless router we have in our office and the problem went away immediately. :-)

I'm not saying this is the cause of everyone's battery problems (I suspect there's a number of different issues going on here), but it's something else to try.

The way to quickly test if it's your router causing the problem is to turn off wifi. If you're getting phantom usage and this fixes it, then I suspect your battery issues may be router related like mine.

Unfortunately, your genius friend is wrong on this.   iOS5 has caused the same problem on iPhone 4 and 3Gs models as well as the new 4s.....    That evidence alone, makes it impossible that it's a hardware problem.

Hello all...My Iphone 4s was perfect until las week. It shows the same time on usage as on stand by mode. I bought my phone in Canada and I´m from Brazil...bad news for me. I Tried to Reboot, deleted my recent apps, restarted my phone...tried almost everything. I already bought this phone with the 5.0.1 uptade. The battery isn´t terrible, but it is bad. I mean, the first week of use, was lasting 2,3 days. Now 1 day in stand by and it´s gone. I notice that some times the phone is hotter. Can u guys help me? Sorry for the english...
