Q: iPhone 4s Battery Life?

dkalchev

are you on push or fetch emails?

thanks

@sbailey4 thanks. I was at 70% and ran my video till I depleted the battery.

The items I mentioned can be done in a few minutes without iTunes. That may very well fix if for you immediately if you want to try it. The network reset is fast. Reset all settings only reboots and makes you run through the wizard of what you want on. Keep diagnostics off when asked. Otherwise restore wit 9A406 if neither of those do not help. If you restore fully to 406, I would re-sync from iTunes not restore backup.

Thanks a lot sbailey4 and dkalchev.

 

I will update my phone to 9A406 over the weekend and report any improvements.

 

Although dkalchev, did you "Restore from backup" after updating to 9A406 or "Set up as new phone"?

I discharged my battery yesterday and charged the phone fully overnight and unplugged it at 7:00 this morning.

I'm still at 100% battery 3 hours later. I would nornally be at about 96% at this time.

Yesterday I emptied my car's fuel tank...

Today I filled up my car and I've been driving for 3 hours and the needle stays on F. I guess my car doesn't consume fuel anymore...

What a comedian! Don't quit your day job!

HAHA you have a car? Figured you would use a bike or horse and carriage to coincide with no TV, no cell phone, you know, anything that may be misconstrued as a "status symbol"  LOL Couldn't resist.

Can sbailey4 please do the calculations here?

3 hours, 1 minute usage

1 day, 19 hours standby

30% battery remaining

I used 3G hotspot to connect to my laptop for about 15 minutes and it dropped significantly, probably 10-15%. I listened to music for about 10 minutes when I was having a run, 20 minutes music via bluetooth in the car, and the rest is play time, Temple Run. It's such a good game considering its for free. I had a few calls, probably 15 minutes, sent+received text messages, had wifi on for about 30 minutes.

I'll sum it up:

Usage: 30 min wifi, 15 min hotspot, 10 min music, 20 min music+BT, 15 min calls, 5 min texts, [let's say] 1 hour Temple Run, and the rest is the phone doing nothing.

Hope you can help me sbailey4.

Ok so looks like 43/200= 21.5% stdby .5/40= 1%  music .25/8= 3% phone and 2.25/6= 37.5% internet so 21.5+1+3+37.5= 63% expected usage so roughly 37% remaining expected. You are at 30% so seems about right I would expect. This is not a science just a rough estimate based on Apples max spec.

That's wonderful, you're so good at this! Thanks alot!

I was in great need of internet and there wasn't wifi at the clinic as I was there for intern and I was working on a very important project.

I guess without the hotspot, the results would've been much better. I barely use hotspot anyways. The music definitely didn't take 1%, it took much more, probably 3-4%. I think you mean 14% off, not 30%. Its looking great keeping in mind I had hotspot on, at least it looks great for me.

For those, who say the 4s lasts 5-6 days in Airplane mode, even if it has the battery drain issue or not (thinking that the problem is with the radio chip) I must say it isn't true, at least not in all cases! Last night I put my 3GS (5.0.1) and my 4S (5.0.1-9A406) next to each other, switched them to Airplane mode and memorized the battery percentage: 3GS - 74%, 4S - 42%. It was around 1 AM. When I woke up at 10:15 AM, I looked at them, to see the battery levels: 3GS - 72%, 4S - 29%. I know, the battery level decrease is not a linear thing, but this difference is so big, that I think this must hardware problem. Now I decided to give a chance for the upcoming 5.1, and if it doesn't help (and I'm afraid it won't) I will take it to the ASP and try to get replacement. For those, who might say, it could be caused by backgound processes: my 3GS ran 21 processes in the bacground and my 4S ran 6. Some might say I'm not using my phone correctly (I read comments like this previously), but it looks like I can't use only my 4S correctly, cause I had no problems like this with my 3G and 3GS...

First, you need to understand that the 3GS and 4S are radically different machines.  The 4S has at least twice the storage, and twice the RAM, and twice the processors.  As for having 6 processes on the 4S, mine usually have closer to 30 going.  It's not so much how many as what they are doing.

If you phone gets you from morning with a full charge, to evening with 50% or better, then it is doing very well for a phone of this type.

Thank you dkalchev, I am in office right now and dont have charger, its gonna on 2%,  usage about 6 hrs 41 mins and standby of 18 hours and 36 mins.......... location services off only siri and maps on ,,,, and timezone off, bluetooth off, wireless off, push off,,,,  brightness less than 40%. What can you say about my iphone battery. The procedure you told me about updating, that I will try at home, when I will arrive at home thank you

Unless your office doesn't have any computers, you should always carry your USB/Data cable with you, just in case.  6 hours usage is pretty heavy, especially using maps.

Conical gas tank?  Grin.

You're right, I just couldn't imagine, how is it possible, that the two years old 3GS battery last more than 3 times longer than the brand new 4S batt with the same settings. Of course there must be lots of differences between the  two softwares and hardwares, the 4S's is more complex, but I simply didn't think this causes such a difference. The "50% in the evening" fits on my case, so maybe I just turn off showing battery percentage, not to see how fast it's draining Thanks.

Just my 2 cents here:

I had an iPhone of the first series (Austria, late October), and the battery life was weak compared to my 3Gs, duration approx. 1 day, sometimes died over night. Update to 5.0.1 didn't change anything, neither partial deactivation of services. Remarkable in particular was the drain without any activity (e.g. 20–30% over night, only for connecting to the WLAN and mobile net???). Not very funny if you have to have a cable with you all the time...

Now I contacted Apple and arranged a warranty exchange, and with the exchange iPhone the problem is solved. i got the phone off the cable at midnight, now it is 23 hours later und the battery is at 67%, with normal use through the day. So that's very ok.

I suppose that Apple has located a hardware problem and solved it by changing something in the latest series. And they keep the solution under cover, because they do not want (and have the capacities) to exchange millions of iPhones. So they reduce the warranty exchanges to those who defenitely use the Apple support hotlines.

I recommend all of you to use the warranty exchange. It'sworth it...
