I heard iPhone 2020 is even greater, it comes with 25MP Camera and SIRI that can speaks in both Hokkien and Hakka...so it's best to wait for 2020 LOL

On a more serious note if you have an iPhone 4 and thinking need to upgrade or not, you just need to ask yourself ONE question - Can you wait for about a year for iPhone 5?

For some its Yes but for me, it's No because I really need the 1080p HD video cam and higher resolution camera because of my newborn baby. I'm too lazy to carry around multiple gadgets and i think the best camera is the one thats always with you..furthermore, I need the camera to be fast, unlike the iPhone 4 unacceptable slow startup...and the extra stuffs like SIRI, noticeable speedier web surfing, faster apps startup time, smoother hires settings for 3D games and fix death grip problem is all sweet desserts to the purchase.

Imagine a world where everyone come to conclusion to things that way...there will be no more mission impossible agents LOL

For most iPhone users:
16GB is ok for iPhone4 but NOT enough for iPhone 4S, because of the 1080p HD video recording, it fills up real quick even if you only use the video cam occasionally.
So to save yourself from the pain of offload the video to your computer frequently, get the 32GB. Unless you hardly ever use video recording, then 16GB should be enough.

For heavy users:
You know well you've been collecting loads of video/photo in your library and never delete them, you have whole season of TV shows waiting to be watched one fine day when you are on a vacation, you are a heavy Flickr/Instagram users taking picture of every meals you have, you have a insanely large music library dating back to the 70s musics, you need all your whole office PDF/documents on your phone all the time, you install every new hot games that is out and keeping them installed. You think you'll skip iPhone 5 and decided to upgrade only after 2-3 years. Get the 64GB.

For those who sell their phone often:
There'll always be buyers for 16GB, 32GB and 64GB and the prices will usually depreciates similarly for each models. Maybe 16GB will be easier to sell later compared to 64GB because the asking price will be lower.

9A406 is only to resolve SIM card problems, not battery.
Don't border updating because its a huge download (800+MB) and the pain of backuping your phone and stuff.
Just wait for 5.1

The best way to resolve the battery issue now is still to do a fresh clean state install without restoring, like a new phone.

And on the issue of Backup/Restore, just avoid using iCloud Backup now, it will be a nightmare waiting for 1 minute for each photo to be restored. Backup via iTunes.

Looking at your screenshot, it shows you got plug in to charge in between...of course get that battery life la ;p

Most likely caused by an app, in fact most battery problems on ios 5 (regardless of iPhone 3GS/4/4S) are caused by apps that were not optimized/coded well with all the new APIs and features in iOS 5. Examples are apps that try to connect/crash continuously in the background, draining battery in the process.

I'm testing mine now and I will take the screenshot just before I charge, more accurate

The best way to preserve your iPhone battery is actually to plug in to power all the time

I know this sounds silly but if you spend most of the time in front of your computer while working, just plug it in and continue charging it. This way you will not waste your battery charge cycles. Lithium ion battery especially Apple will not overcharge and once it's full it will auto switch off and use from DC. Unplug it and use it like normal when you need to go out. Once a month, trickle charge for extra 2 hours for 100% and let it drain to 0% without pluging in. Leave it off for at least 5 hours and recharge back to 100% and turn back on. This will both calibrate back your battery and keeping the electrolyte inside running healthy.

This method is for those who want their phone to hold charges well above 80% after more than 3-years of usage. I did the same for my 3GS and it's battery is still superb.

For most users though, normal charge-use-discharge-use is fine and can replace the battery with use up charge cycles after 3-years.

Same as mine, quite close to what Apple claimed that for 3G is about 6 hours. So much better than my hopeless so-called high end Samsung Androids

Not normal, I suspect caused by some apps connecting and crashing in the background at nite continuously. Check the crash report from Diagnostics and Usage. It should be 94-98% when idle for that long.

Same as mine..thats about right.
Apple estimates about 6 hours.

whoa, that's alot of misinformation there bro. jus an advice, it will be more helpful to others if you read more before posting this.

below are common facts that you can find from all those reliable sources including from Apple and wiki:

1. For LiIon battery, you can charge at ANYTIME (not half, 30% or 40%) unlike nickel-based batteries
2. It will not burden or damage the battery if you charge it at 1% or even when the phone turn off by itself because there is a reserve battery after it is switch off for battery protection.
3. You don't need to ALWAYS do full charge, the diminishing cycles are automatically calculated internally from the total 1,000 cycles available for Apple LiIon batteries. This means, if you use your iPhone until 40% and charge it back to 100% (used 60%), and then you use up and it drop to 20% (used 80%), and you charge again to 100% and it drop to 40% later (used 40%). So the total use-up cycles for that duration will be 2 cycles from the 1000 available because (60%+80%+60%=200%=2 cycles).
4. The maximum duration of time you need to do a full charge is ONCE a month, not ALWAYS. And this battery calibrating exercise is to make the battery level reading more accurate on your iPhone and keep the juice inside active running. But if you want to do full charge always also can, thats the good thing about LiIon batteries, you can charge whatever ways you want.
5. In fact, the best way to preserve your iPhone battery is actually to plug in to power all the time.

I know this sounds silly but if you spend most of the time in front of your computer while working, just plug it in and continue charging it. This way you will not waste your battery charge cycles.

thats old nickel-based batteries..it's ridiculous how often those people from phone shops still giving such obsolete advice to customers. no wonder so many ppl confused.

either way oso can, it's up to you. if you do trickle charge, youll notice your battery can lasts abit longer for single charge.
my advice is not to worry too much about battery maintenance for your iPhone. just enjoy your phone and charge it whenever you need to.
the problem of memory problem and overchraging are bygone history. and using an apple products especially, they are quite in the forefront of
battery technology, we don't need to fret to much over this.

but one fact remains, any battery regardless how well we maintain it, will diminish in performance the day we started using it.

Added on December 27, 2011, 4:20 pmno problem, i've been doing this for my iPhones and MBP for years and their battery performance still above 80% of design capacity.

UNLESS your charger is faulty or not the genuine one, inadvertently charged to a higher than specified voltage.

yup, especially Apple products because they are leading the industry in battery technology R&D

Tak bole but you can throw it into a folder by dragging another app to another app to create folder and right before you release it drag the newsstand app instead (need to be quick)...this hack will crash when the newsstand is tap though...

This will probably be the most unApple-like experience you will ever faced using an Apple product. There are 15-steps to do that if you really want to know

A quite good and comprehensive guide from iBooks Store. And it's FREE.
