Q: iPhone 4s Battery Life?

Have heard that WhatsApp has caused a few other peoples devices to drain battery. May want to remove that while you wait for your 7th new device. Also I hope you are not restoring backups from the othe 5 faulty devices. If you are you may want to consider trying a fresh setup as new  and not installing ALL the same apps again. If there is software corruption you can get 25 devices and they will all have the problems if you contunue to restore corrupted software to them. Not that you are cause i have no idea but it is more likely there is software corruption causing your issues than 6 faulty devices that have hardware defects. Same goes if you are installing all the same apps on all the devices. Could be 1 or 2 apps creating all your trouble, As I said I have heard a few times that WhatsApp was an issue for a few folks that once removed battery was right where it should be. Let us know how Lucky # 7 works for you!

There is an App that monitors Battery Status, Disk Usage, CPU Usage and some other things. If you go to the App Store and Search for CPU Usage, there is a Free one called System Status that will do this. Check it out, it was very interesting. With everything possible turned off on the iPhone 4s you can still see the CPU is operating. (which it probably should be doing) I'm having the same Battery drain problems as most everyone else. I don't think anything we can do will resolve this problem. Come on Apple, fix it!

 

One question: Did anyone notice that if you turn off "raise to speak" for Siri, that it doesent disable the infrared sensor? (Hold it in front of a camera and you'll see that it is active all the time) or is that just for my handset?

 

I have verified this operation: If Raise to speak is off, and turn off iPhone (may have to twice) the sensor is off unless you make a phone call then it comes on until you hang up. Works like iPhione 4. If Raise to speak is on,.  anytime the screen is on so is the sensor but when screen is asleep the sensor is off.

Thanks, I have seen some of these. b4sxy seem'ed to have one that perhaps help him/her pinpoint their particular issue. He stated that now battery is working fine so it sorta seems like this app helped him figure it out.

I am curious because of the 97% in the morning issue while on charger. I see my phone on 100% all night then earlymorning shortly after 6:50am or so it goes from 100% to 97% by the time i look at it at 7:15 when i get up. Only when wifi is on otherwise stays on 100%. If i have wifi off its fine until i turn it on then soon after it drops again (maybe if i turn it on at 8:00am for instance). No other issues all day just that certain time in the am. So was hoping something like this may pinpoint what the heck wifi is doing at that time of day every day. Not iCloud backup, that runs at 11:00pm and i have turned it off to trouleshoot and no difference.

OK.... I did the reset settings, configured optimized settings and after that I made a backup on iTunes.

Then I installed 9A406, and restored the backup (with optimized configurations)

Now I will drain the battery until it goes off and leave it charging all night.

So, I'm mixing both solutions. What do you think?

I'll be back tomorrow with my results.

Thanks

well  sounds like you covered the bases. Hope it helps!

Hi sbailey4,

Yes the probelm is related to WhatsApp. But I find out that it's located in the Notification settings. Have try the settings for a weeks. Now my iPhones 4S can last 2 days (from usually 10 hrs before change the settings). And now my iPhone no longer overheated like before.

Settings > Notifications > WhatsApp

Notification Centre: Off

Alert Style: None

Badge App Icon: On

Sounds: On

View in Lock Screen: Off

So the bug is either in the Notification module or in the WhatsApp it self..

Please try it and let me know your result..

Hmm well could be but what are the odds that you got 3 in a row of faulty hardware.

What are the odds of  1 +1  = 2 ?

What are the odds of phone call being dropped on a iPhone 4 when one uses the death grip?

Here one has the wrong assumption to begin with! The wrong assumption is that all iPhone 4S have no hardware issues!!! It has already been shown that 80% of iPhone 4S have hardware issues regarding the static noise!!! Most of the Apple stores most likely will not swap a iPhone 4S if one complains about the static noise issue because they know that most of the iPhone 4s are affected by it!

Of all the millions of iPhones out there that are for the most part working great

This is wrong! Most of the iPhone 4S are not working great! It is has already been shown that 80% of iPhone 4S have hardware issues regarding the static noise which is related to a faulty chip!!!

Also from the posts on this forum has emerged a pattern which shows that iPhone 4S users which keep off all the time Wifi and Cellular Data (or do not have Cellular Data plan) get a good battery life! Otherwise the battery life of iPhone 4S is miserable and it is much worse than iPhone 4!!!

No offence, but where do you get a figure of 80%? Anyway moving on, I have had horrendous battery issues with my release iPhone 4S 64 GB model. Now recently it started to behave oddly, the screen flashing on and off fast when coming out of standby, and panic.plist showing up in logs as the phone rebooted while not being touched this indicated hardware issues. I have just had it replaced, I was not happy to say the least.

Now my new iPhone 4S has now reached 16 hours 59 Minutes standby with 1 Hour 41 minutes usage and I still have 78% battery left, this is on first charge and using a restore of my previous iPhone 4S. This phone has no sim pin issues as did my first, wifi is on all the time and send diagnostics is turned off, I have i-ads and diagnostics turned off in location services as per my last one which would die at 16 hours with about 11 hours of phantom usage all other system location services like timezone etc are on. iMessage is on, so is facetime, weather has the local function turned off as I dont use it, push email is turned off also. I now have a functioning iPhone 4S with great battery life so I am confused, the phone came with version 5.0 on it, I updated using the delta update over wifi to 5.0.1 it pulled down the old 5.0.1 version not the new one. Take from this what you will, but its odd that the new phone works fine, the old one struggled to get to a day.

As to Statistics, no one can say 80% of iPhone's have hiss or battery issues, no one has those figures, but the problem is huge, so now I am wondering if its the A5 chip itself that is the problem on earlier versions. Who knows what the issue is,  but I wanted to throw my situation into the mix so people know that some iPhone's do work fine, and no one is more surprised than myself after my last handsets abysmal behavior.

No, it is no offence. It is a good question and I am glad to answer it! I have seen this figure in some article in a Korean newspaper. After this I did a poll on this forum (you may see it many pages before) and also among my friends with iPhone 4S and it is approximately 80%.

Have you checked if your iPhone 4S has the static noise issue (go in a quite room, turn off WIFI, turn on Cellular Data, load a large webpage in Safari and immediately put your ear on the back of the iPhone 4s where is the apple logo and listen => if you hear some noise than you are affected by the static noise issue)?

Now recently it started to behave oddly, the screen flashing on and off fast when coming out of standby, and panic.plist showing up in logs as the phone rebooted while not being touched this indicated hardware issues. I have just had it replaced, I was not happy to say the least.

Sorry to hear!

Is your cellular data on?

Are you connected to a 3G or 2G network (note: 3G network is different than hacing Celular Data off; not all places have 3G coverage)?

Do you have 3G network coverage?

If your Cellular Data is off and your phone connects to 2G network it might explain your very good battery life!

As to Statistics, no one can say 80% of iPhone's have hiss or battery issues, no one has those figures,

I have the figures. A small poll which is well conducted can give a very good general picture! Polls are used for elections, in medicine (for assesing the drug side effects), etc. There is science behind polls and they are NOT voodoo!

I love to use apple

but this time with iphone 4s

I'm so disapointing

same man, apple should cut the price of iphone 4s due to this ****** battery problem. they are essentially lying to the consumers about the specs and so i hope some ppl sue apple for this mess. this whole issue is disgusting !!!!

@Iphone 4s lover

Indeed a company should not be allowed to sell such a product! Already Apple got fined for not-so-nice-practices in Italy! Hopefully we will see something similar for iPhone 4S! I am really amazed that no major news agency is reporting the issues with iPhone 4S though!

Another issue which I noticed with iPhone 4S is that the voice quality during a phone call (1 in 10 phone calls) can be some times pretty bad (like the other person is in a speaking in water). I have never had this kind of problem with any other phone in the last 10 years! Also I get 3 bars (out of 5) for coverage in my office even that on the other phone in the same spot I get the maximum bars!!!

It looks to me that iPhone 4S is even worse for phone calls than a dumb phone. Definitevly the best phone which Apple has ever done is iPhone 4 (with iOs 4.3) and not iPhone 4S!

Try deactivating all apps "preview on lock screen" and select "none" for alert styles. Just limit the notifications to the notification bar. And for those who hasn't gone thru the discharge cycle, do it atleast once. This will help some batt issues..

Regarding the voice call issues, i think it only happens when you are in a weak 3G area, and the fone trying to switch to 2G while still on a call.
