I noticed the battery life is still poor when location service for clock is enabled. Possibly due to the fact it stays on all the time when it should go off once local time is synced. So in my views it may have improved in other ways but not for location services. I guess it's not a big deal as you can manage time manually. Only thing I noticed on my 4s the time keeping was less consistent as it kept slowing!. May sound weird but I know I set clock and it slowed against other clocks in the house. Plus side it fixed the 3G option where you can still have cellular data on while having 3G off. Handy when you don't need 3G.
The poor signal is likely a real-life reflection of what was really the case before the patch. It was giving the impression that reception was high, but it really wasn't. Now it's giving the correct signal reading.
My battery life increased with 5.0.1, but has SIGNIFICANTLY decreased with 5.1. I wish I could downgrade. I'm using the phone the same amount and my battery life is at 26% near 2:00 in the afternoon where it had been around 70% at this time of day with the same amount of usage. It's crap.
Same here, my 4S battery life is a little worse than my 4 was, but I still get through a whole day without charging. I also stream sirius/xm radio app for 3 to 6 hours a day too, and use it for various other things throughout the day.
I have a 4S since Jan, using 5.0.1. My battery lasts about 2 full days with about 4-5h talk, 1-2h internet on 3G or wireless, but in the best case scenario it lasted 4 full days several times already (same total usage). In the worst case scenario it lasted one full day (intense traveling runs the battery down, I noticed that thing too)The one thing that I am religiously doing is charge it full cycle (almost) every time, using BatteryDoctor. So I the only full month that I had the IPhone (February), I charged it 11 times, out of which 9 full cycles, and 2 normal cycles. I do turn off wireless, 3G, bluetooth, and push services, and I am pretty happy with the battery life. I was going to update to 5.1, but after seeing your comments... I'd rather not!
Dears,i think you didn't face such issue because you doesn't have 3G service, you just use the wifi on your Iphones .... me ... i am suffering from it ... and too many of my friends here in kuwait...btw.. still i didn't update .. waiting untethered jailbreak ... but i hope it will fix this issue ...
Kingsoft Battery Doctor Free is the best battery management software that i have installed and tried so far. After upgrading to IOS5.1, and installed this, my battery life is prolong and last longer than my previous IOS5.01 on my Iphone 4S. Previously my battery will drained by 6-7% from full charged at 7pm to 7am, now with Kingsoft, it just drop 2-4% for the same period without any activity, wifi switch off, location service is off.Try it and you amazed.
As soon as I upgraded to IOS 5.1, the battery started draining almost 1% per minute. Tech support hasn't helped much. Found 26 pages of people with the same issue on Apple community forums. The upgrade may be working for some in terms of battery life, but it seems that for about 10% of 4s owners, battery life has gotten drastically worse, not better.
If u didn't update I strongly recommend that of you are happy ad comfortable with your jailbreak don't update sure the new update does fix this battery issue but one thing out there for AT&T users it also brings 4G connectivity which is non reversible so at the same time you got battery fixes and 4G to almost cancel it out almost completely so in the end it doesn't matter
I had NO issues before the 5.1 update, now battery life is terrible. The battery drains at a rate of about 1% every 7-8 minutes. And the WiFi loses it's lock with my access-point and won't reconnect until i power cycle the phone. What gives Apple!! I repeat... I had no problems until this last update. Anyone know a way to downgrade?
