Q: iPhone 4s Battery Life?

I found a way to fix the poor battery life on the iPhone 4S.  All you have to do it turn your iPhone off whenever you are not using it.  It only takes 1 minute to power down and about 1.5 minutes to power up because of the improved chip.  Unfortunatly, you have to press the power button, SIRI can't turn off the iPhone yet.

Intriguing idea. I am going to try it our right now. I would be disappointed if one of the main features of iOS5 is unusable, but will live without it to get better battery life.

I was having the same problem. Then my battery completely died. Couldn't even turmn it on for a second.

Let it charge up over night and now it seems to be working fine......I have no idea how that could of fixed it. I did not reload anything, or reset it.....I wonder if there is something in the memory from the manufacture causing the problem.

Just following from my own post :

Been off my charger for 6 hours and still not dropped from 100% .  Connected to my home wi-fi all that time and not doing anything but most things ARE enabled like cloud and notifications and it's  reveived about 30 mails using fetch.

As soon as i leave home i know i'll be able to watch the % fall..

So my issue seems to be complete 3g related.

I echo everyone else's frustration. My iPhone 4 would go all day before needing a charge. The 4S gives me about 6-8 hours with the same setup as the old phone. Definitely not up to Apple standards. Starting from scratch did not help.

My  4S would last only 4-5 hours, so I looked at location settings, wifi, etc...all normal.  So I decided to let the battery completely drain, fully charge it  and it did for the three days straight and it seems like it resolved my issue.  The battery lasts longer than my 4 did!!!!

It's worth a shot...

Hi guys,

as promised here is the feedback. I'm sure i have found a solution.

Before fix:

6 hours standby and i lost 20% of my charge

After fix:

10 hours standby and i lost 4% of my charge.

(Measured pure standby, WiFi, Bluetooth, Location Services, PUSH Notification all were OFF)

If you have battery problems restore your IPhone with iTunes and set it up as a new Phone.

new phone calibration is in order. 2 complete discharge ( till phone shuts off ) and full charge will calibrate any LIPO battery system, and is a standard in using LIPOS.

Also all apps that you have opened STAY opened until you close them ! .

Double tap the home button to enter the app dock, then touch and hold any app to activate the close funtion. You will know see a sign on each app. Just touch the to close ALL apps )

I put my new 4s on the charger every other day and use about 10-15% only daily !

Thats it, JUST TURN THEM APPS OFF.

You can keep everything else on. ( turn wifi off when you will not be any were you use it and save even more juice

Although this is my first iphone (4s), I didn't notice anything abnormal about battery drain or overheating issues for the first few days.  In fact, having come from an Android phone I was pretty pleased.  I then went to the Diamond Heights area of San Francisco for a day and noticed that the battery was draining 1% per every few minutes.  Additonally it seemed abnormally hot (burning a hole in my pocket hot) even though I had not been using it for anything other than checking email.  I put it away and a couple of hours later I noticed an "Invalid SIM" message.  I turned it off and on several times and did a couple of hard resets.  Nothing worked, I continued to receive the "Invalid SIM" message, and I was about to head to the Apple store when I decided to Google any possible fixes.  I found one that suggested popping the SIM tray and reinserting.  I did and it got the phone back in business.  I left the area and the phone seemed to work as normal again.  The next day I returned to the Diamond Heights area for work and the phone started heating up again with significant battery drain although I never got any more "Invalid SIM" situations.

I haven't been back to that part of SF since and it seems as if my iphone has been working fine with normal battery drain and no significant heating.  Although I don't have any data to pass on I can say that I have bluetooth off, 15 min fetch on email, wifi off, iCloud with reminders and find my iphone only, and very few apps on board.  I am wondering, based on my experience in Diamond Heights, if there is an issue with the way the phone handles being transferred to different or certain cell towers.  I don't have any background in cell technology, but thought it strange that my phone's behavior was isolated to a certain geographical area.

Same problem here. Thursday night saw a genius and he changed it for me after checking my stats and saying "thats not normal for a new phone". Got home, synced and still same issue. Just lost 5% battery in 5 minutes while surfing on wifi.

I tried turning off everything that was possibly turn off-able.

Removed email accounts, rebooted, reset network settings, Siri, notifications, location services... I basically started at the top of my settings page and turned off everything one by one.

Nothing fixed it.

On my first 4s I was loosing about 10% an hour while phone was in my pocket. With this iPhone 4s I'm loosing more randomly, from 5% an hour to 15%.

My feeling is that it's a bug only people "upgrading from previous iPhone models" are getting.

Hopefully Apple will fix this soon, and hopefully it's a software bug. :)

Tonight, I left at 8pm with 69% battery life on iphone 4s. Screen was on really low brightness and not used for three hours, BUT as of 11pm, my phone had 2% and died shortly thereafter! This is terrible; the battery is not even nearly as good as my iphone 4 was...im not a happy customer

I have a feeling that the bug is linked to people upgrading from previous phones and re-syncing previous backups, and I believe you that your fix works... But I really don't feel like loosing all my contacts...

Hi guys,

I received my brand new iPhone yesterday (after a 5-hour queue).

I proceeded to do a full 8-hour charge, before restoring the phone from my iTunes backup (of my old 3GS) after activation.

After a complete restore (about 200 apps on it), I left the phone in airplane mode, (without a Simcard, as I've yet to convert my sim to a microsim.) and the battery life was 96%. This was 1am. I hibernated the phone before going to bed.

When I woke up at 8am this morning 7 hours later, the battery life reads 34%. Completely shocked me. This averaged to a drop of 62% in 7 hours or an average of 9% per hour, in airplane mode (ie no wifi, no location, no 3G etc).

What gives? Anyone has any ideas?

I saw some solutions posted in this thread about restoring my phone as a new phone, but I dont want to do that because I do not want to lose my apps and the data in them.

thanks!
