iPhone 4S 5.0.1 Update Improves Battery w/ Settings Reset

The battery of my friend's 4S hardly got below 75% after a whole day of heavy usage. Hope I can get that result someday.

My 4S would be at like 40% to 50% after a day of almost no usage. Every method I can imagine has been tried multiple times, and got no difference. Not even a bit.

Perhaps I should count myself lucky, as those frequent resetting, restoring and recharging are not making my battery worse :-(

I'm wondering if the reported battery life by Davidch is with only making calls, and other than that it's just in standby mode?

Does this mean no wifi, games, or other use at all? I am finding that after updating to 5.0.1 my battery life seems worse, so just wondering if I should fully charge and then just keep it in standby mode other than for calls.

Also, if for example, I do a full charge to 100%, leave it for 8hrs in standby mode, and have 96% left. Is that a good indication that I do not have a battery life problem, or could I still have the issue but just not in standby mode?

Thanks

Hi All

Will Davidch's procedure work with iOS 5.0.0? I am a little leery of updating the phone to 5.0.1. Also, does the act of resetting all settings and setting up as a new phone force you to update to 5.0.1?

Thanks in advance,

Frank

Dear david,

Do i need to fully discharge my iphone 4s before i do the re-setting etc?

I have updated my phone to Ios 5.01 few days ago, but it doesn't seems working on my phone to solve the battery drain issue, so i would like to try your method,

so basically is just go setting there and reset everything, then go location service and turn off the IAd and time zone, then use the phone until the battery drain off then fully charged it then done?

because after i try to reset everything besides "fully discharge and charged" , after resetting it, the battery still drain quite fast as in, i only using my whatsapp, and the battery drop from 64% to 60% in 10mins =(

I guess there's still some kind of battery problem existing in your case, especially if let the battery drop from 100%, since it takes longer to drop the first 1%.

My friend's 4S just dropped from 80% to 79% for like 6 hrs in standby!!! So jealous of him

6hrs to drop 1%!!!!!???

oh my.. if i play game, is less than 1 minute then drop 1% =(

"I guess there's still some kind of battery problem existing in your case, especially if let the battery drop from 100%, since it takes longer to drop the first 1%."

This is incorrect. On average the phone should drop 0.5% every hour in standby. His standby times are fine.

I last done a full charge on friday night, i put phone on at 4.45am saturday and its now sunday 1pm and i still have 57%. I did turn phone off about 9pm saturday night, and put it on today about 8am. I had music on for about half hour, and played games, and a few calls, and LOTS of textes.

I have a 4s with this 5.0.1

I hear 5.0.2should be with us in the week.

So what I've been noticing is that my iPhone's battery is fine on Wi-Fi. It's just a lot worse on 3G.I understand that the Usage of the phone is a lot better on Wi-Fi than 3G, but I don't think it should effect my Standby drain as much as it does on mine. When I'm on the 3G the whole day, the Standby drain is much greater than if I was on Wi-Fi the whole day.

Ok I don't think my 4s's battery life has been all that bad my stats as of now are 59% battery, 2hrs 5 mins of usage and 1day 11hours of standby. I haven't tried resetting settings yet I am going for a before and after thing and I'll let you guys know my results. But my iPad 1's battery life has definitely dropped since updating to 5.0.1 I'll test on that also. I have iAds and time zone locations off and on my 4s I have siri's raise to speak feature off because I noticed that the proximity sensor was constantly running (I checked it with my old 3gs's camera) and noticed that even after turning raise to speak off the proximity sensor was still constantly on but a reboot fixed that. That's another thing you guys can try and see if battery life improves. Anyways I'll report back probably tomorrow or the next day to show my results.

Ok just reset setting and again the proximity sensor is on constantly and turning off siri's raise to speak and the sensor stayed on and this time rebooting didn't keep the sensor off. It can be checked with an old iPhones camera. I can't get it to turn off now. ***** anyone else try this and let me know how it turns out.

Ok it took me 3 hard reboots to get the sensor to stay off.

Well 5 hours have gone by and i still have 45% only used 12% in that time 😎 and been playing on phone.
