I upgraded to iOS 5.0.1 beta2 last week and saw a big improvment. Mine is a first-day pre-order 4S. I think the build week is 42.
In 5.0 I wasn't seeing dramatic drops in battery life while the phone wasn't being used, but I was seeing a lot of battery drain while the phone was in light use. After 6 hours of standby and an hour or two of light usage (email, few texts, and a couple games like Words and Chess) I'd be at 40-50%. During part of this time I also had the "Automatic Time Zone"and "Diagnostics and Usage" set to on in location services. I turned those off and saw some improvement in 5.0, but not much.
After installing 5.0.1 beta 2 (and keeping "Automatic Time Zone"and "Diagnostics and Usage" set to off), I was getting the following results. The one thing I did do after installing beta 2 was to do a full charge and then completely drain the phone until shutdown. Then do a full recharge again.
This screen shot was taken after moderate usage over a 24 hour period. About 3 hours of music, then about an hour of streaming music via bluetooth, a few pictures, a couple hours of games, a little web surfing, several texts, 30 mins of phone use and a few photos. About half the time I was on WiFi and the other half 3G.
Also, I have always had iCloud and Ping turned off.
since you have good battery can you share some statistics like 10mins of 3g browsing how many % drop, or 10mins of wifi, what do you have on and off, so we can see what is a good battery for you
for me a good battery is a battery that lasts 2 days whit normal usage, some calls,texts, some 3g browsing couple of games and lasts for 2 days
or heavy usage 1 day
I'm not sure if it's better or worse at this point. I never had the major battery drain that some posted here and I have everything except BlueTooth turned on (Siri, iCloud, Location, WiFi, push, etc). Brightness is about 33%.
Currently my phone is at 92% with usage at 26 minutes and standby at 3 hours, 45 minutes.
Based on Apple's specs, when using the phone on 3G, battery should drain 1% point every 3.6 minutes. At 26 minutes that would be about 7.2%. That would seem to mesh up, but I wasn't using the 3G constantly for those 26 minutes (actually I probably didn't use it for more than about 15 minutes) and some of that time I was on WiFi. I did use some apps that activated the GPS briefly though.
Comparing this with the post I made last month while running iOS 5 and it appears the phone drains faster under iOS 5.0.1:
IOS 5: Battery Percentage: 98%, Usage: 17 minutes, Standby: 4 hours, 58 minutes
Though without an Apple to Apple comparison of what I was doing it's not really a valid comparison. I may have gotten more push notifications and e-mail today. Also the simple act of checking the battery life will drain the battery.
Also 5.0.1 only fixed specific problems with battery life in iOS 5. Unless you were having that specific problem, iOS 5.0.1 won't do anything.
I'm at 85%. Boost Magic says I have 6:48 of talk time and 8:30 of internet wi-fi.
Battery Magic says 6:09 of talk and 8:30 internet wi-fi.
6+ hours of talk time?????????? HAH How is a software fix gonna give me that???? I lost 15% just checking email and stocks! If I actually used it as a phone.......
Apple, stop with the denial and get to reality. Maybe you should contact some of us ACTUAL users having the problem rather than your engineers.
What I hope Apple also realizes is that for every person posting on this forum, there are 100 more who aren't that are having the same problems. You can't say it's a "small number of people" with these issues because most people will not come to a forum like this...they will try and deal with it themselves, go to their carrier, or go the Apple store. I truly hope Apple starts communicating FAST... I have always expected the best from them and have always got it, but this is getting way out of hand.
Yes, exactly! Not everyone knows these Apple forums exist or are computer savvy.
Another thing: While Apple monitors these boards for violation of TOU (I've had 2 posts removed that should not have been), Apple would be VERY unwise if they did NOT read these forums. This is the.biggest.feedback. for them to receive 2nd to people submitting feedback via their feedback forms.
Everybody here should CONTACT APPLE TECH SUPPORT and complain. Once their call centers are overwhelmed they will realize it's not "A SMALL NUMBER OF USERS" who have this problem.
Seriously! Contact Apple Support and make them tell you how to get close to the claimed battery life. They need to be told, and maybe they can offer individual fixes (yeah, right).
a few pages back somone posted about 'apple News Headline', half jokingly. Well maybe that's not a bad idea. It seems that perhaps there has not been enough mainstream news about this issue. The other night, for example, my local news ran a story where Consumer Reports (who prooved themselved to be a joke with their report) reviewed a latest batch of smartphones including the iPhone 4s and they gave it a good review, making no mention of the issues many of us are facing.
Maybe if we all start hitting the majors with this... CNN, New York Timest, Fox, MSNBC, etc.. Nevermind slackers like Wired or other tech specific rags. Lets make our voices heard more publicly than just these forums.
WHO'S WITH ME!!!!! <raises pitchfork high in the air>
If you are having a lot of trouble with your battery life, turn OFF iCloud.
That little advancement with iOS5 is what is causing a LOT of battery issues. If you have a lot of data on your phone, like one of my practices doctors (40,000 pictures) and counting, your data to the cloud is running ALL the time.
Turn it off under your settings and you will see a big improvement.
