iPhone 4s Battery Life?

I totally agree with this last post. I did have terrible first two days of battery, after couple calibration my battery seams better, not an iPhone 4 performance, but much better.

This is my last usage details:

Re: iPhone 4s Battery Life?

Oct 19, 2011 2:06 PM (in response to MacBook it works)

Gang here is my update usage after the second full calibration:

Usage: 6:10

Standby: 1 day, 3 hours

Data: sent 12.2mb and received 91.2mb

Call time: 55minutes

I put it to charge at 11:45am and at 1:45pm it was 100% charged.

I had at least 7:30 hours of usage on my iPhone 4 doing the same things I do with the 4S. Also, I did not turn anything off. Mail is set at fetch, iclould is on, weather is using location and clock is using location.

Is this a normal usage for this new iPhone 4S?

Thanks,

I seem to have fixed my battery problems which were worse than my old 3G... I don't know what it was that actually fixed things, but I did the following:

Turn off Documents iCloud syncing

Turn off Location Services I don't need (and System Services > turn off everything
Turn off notifications I don't need

Push email but Manual iCloud of Calendars, Contacts and Reminders. (They don't need to be Push because u only see them when you go into the app anyway)

Turn off automatic set of time in the Date and Time settings

DId a hard reset

Still have Wifi on and Push email for one account. I am allowing lots of apps (but not all) to know my location and note that I restored from iTunes from old phone.

I think it was the hard reset that did it. You hold the LOCK and HOME BUTTON for 10 secs till it turns off.

I agree we shouldn't have to turn things OFF, but for now until Apple resolve it, it will do. Been on 100% for about an hour, whereas before I was losing 10-20 per cent every half hour.

I just switched on iCloud with all services (including find my iPhone, Photostream and Documents & Data sync) running and the phone only lost 1% in 45 minutes! As per my previous post all location services on, as well as Siri, fetch data every 30 minutes and an exchange account is running. I was expecting a much higher usage in 45 minutes to be honest.

The only thing that has tripled my standyby battery life is switching SIM cards and Resetting the Network Settings.

I'll do more tests.

Just ran another test, switched off Find my iPhone, Photostream, Documents and Data sync and Fetch Hourly. Lost a 1% in 33 minutes. Don't know what's going on there.

I'm going to run 1 more test and then I've had enough of this.

i agree... my battery is back to normal, i turn iCloud on just to back-up once a day.

Turn on off all your mails acounts,gps, bluetooth, notifications, icloud, imessage, twiter, facebook, acounts, and turn on only cellular data and 3g. Charge your batteries till 100% at night. Unplug it from energy, reset your counters (cellular data and use), and go to sleep. When you wake up, go to see your counters.....

After conditioning my battery from approx 5% to full charge for the last 4 nights, I am finding a noticeable improvement. However, this is with quite a few of the services switched off, which I should not have to do.

I am also running a 4 & 4S (both running iOS 5) side by side and the difference is still considerable.

After 4.5 hours of marginal use on each, the 4 is showing 90% charge and the 4S is showing 73%

If it was purely software, then surely both should be affected!

I am going to persevere for a few more days but I am bitterly disapointed with the performance to date. If I can't rely on a phone to retain it's charge without having to turn of most of it's functionality and ration it's use, then there's not a lot of point in having it, regardless of how the specs have been upgraded.

I think I will be reverting back to my 4 if this issue isn't resolved soon.

Usually the first percentage drop from whenever you take it off the charger usually takes longer to drop than the second one.. For instance the other day.. i took my phone off the charger and it had 64%. It took it 18 minutes to drop to 63%.. and then from 63% to 62% it took 5 minutes. and then 4 minutes.. and stayed at 4 minutes for the rest of my test....

I set up a ticket with Apple about the indicator not saying 100%. He said it was the software - he suggested I try a restore or reset. I reset the phone. I ran down the phone to zero and let it shut off. I charged it overnight. When I awoke the phone was still at 98%. I left it charge a little while longer and then got the 100% charge. I have a black iphone 4s 32G. I notice now after having phone since Friday that battery life is much better. I have let the phone drain completely twice before trickle charging.

OK last post.

With a fresh restore and all iPhone 4s "features" enabled, including all Location services, SIRI, Exchange Account, Fetch data hourly. Also having the New SIM card inserted. The battery was holding at around 1% every 90 minutes.

I then enabled iCloud, and then the iPhone started eating power like nothing else. If you don't need to use it, then don't. Espeically turn off Find my iPhone, Docs and Data and Photostream.

Do a fresh restore and set up as a new phone. Don't set up iCloud though, it's a battery eater. Well at least it is for me.

I did notice that when i went into Maps and click the find my location button the blue dot was skipping around my location every 1/2 a second or so. So maybe the Find My iPhone service in iCloud is using GPS continuously.

Anyway, I'm done. Good Luck everyone.

Same here. Got my new 4S that I charged for a whole day then installed the backup via iTunes from my 3GS, then updated some 46 apps over my home wifi. I took all the default options for everything.

No calls, no 3G and I'm down to 89% in about an hour, from full charge. This is far, far worse than my 3GS.

What's going on?

I reset my network settings, turned my mail to fetch or manual, and went into location settings to turn of the GPS for both SIRI and in the system services for Location based iAds, Mobile Network Selection and Setting time zone. I then did a backup of the iphone onto iCloud, then restored from this backup.

Recharged it to 100% overnight, have used it for 20 mins (used siri several times and sent multiple text messages) and 1:13 on standby and have just gone down to 97% :) this is much much better than what it was before!!

Let me know if this helps anyone else!

I'd like to add my two cents on my battery drain issue as well. I've noticed since I had the phone for three days now that the battery is not holding a charge near as well as my i4. I have most all my settings set as I did on my iPhone 4 but the moment I start using the phone i can watch the battery drain....I hope Apple has an update in the works to improve the battery!!!!!

Don't know why, but all is well here. I've run the 4S on WiFi for 24 hours and still have 41% left. In the first 15 hours I played with the phone now and then, using Find My Friends for a hour, and with the following turned on for all 24: GPS, iCloud (pushing contacts and calendar), an Exchange Server email acct. with Push, and with a POP email account set to manual/manual (see my other post in this thread).

I have Time Zone support off (not sure if it matters), and compass on, and all other Location Services on. WiFi syncing with iTunes is on, but the phone was not plugged into power so I suspect it did not sync. Documents & Data are off as is the Diagnostics reporting.

I have not used cellular 3G at all during that period. I was always on WiFi.

At 41% I may head out for today without charging and see what happens when I use 3G cellular. Past troubles with POP email fetching led me to change to manual/manual -- that helped battery life on my old 3G iPhone.

Yesterday I ran my 4S and my wife's 3GS phone with the same usage and settings. Battery usage dropped slowly and tracked each other almost perfectly. I was at 50% after 14 hours. Overnight with no usage (but turned on) it went from 50% to 41% in 9 hours.

To the earlier request for better descriptions, my iP4S 16GB is with AT&T. I have Exchange mail and calendars but those are critical to my work. I have closely down much of what has been recommended here, but have not restored the phone as new [I did this with the iP4 one time and it did not help).

I have not kept detailed notes but noticed one day that I started with 92% and was at 37% 12 hours later with very light use like short calls, email but no video, tv, etc.

My iPad 3G has the same configuration but not the battery drain. The iP4 passed on to my SO has much of what I have including Exchange mail and calendar, but the iP4 holds its charge much better through the day.
