I have observed my Nokia 5800 XpressMusic cell to be the finest overall I have owned. Just wish it had a slide out qwerty keyboard! Anyway, it doesn't so more than enough is enough. A good deal of individuals whine about the digital camera, it does suck, but it is not that critical to me-I possess a excellent Canon SD950 camera if I want pics. I'm genuinely please with how customizable it really is and every one of the factors I can perform with it. Needs charging practically daily when utilised a fair bit. Pondering about debranding it. Rogers (Canada) keeps items rather locked down and the highest fw I have been able to upgrade to is v30 (anything like that can't remember the exact quantity at the moment). Sounds like v40 has some good characteristics I'm missing out on.Properly, glad I identified this forum, I hope to learn a good deal far more about what I can do with my phone.

The biggest drain on the iPhone battery is Push Notification, esp in emails that are set to push. Set your settings to fetch from the server rather than have it pushed to the phone. Try setting it to fetch hourly or simply fetch manually. It will surely help save you battery.

I wonder why of all the tips they list, they don't tell you to just hit the sleep button on top of the phone. I think that was one of the first tips Apple suggested when you are not using your phone.

i can't believe how many people are put off by these tips! same thing with the g1 - battery life sucked (actually worse than the iphone) so the advice was to turn off the stuff that sucks power when you're not using it. and then 2/3rds of the responses are "that's why I have the phone, i shouldn't have to turn it off!" good gawd it isn't that hard to toggle stuff on/off and it makes sense to do so. you don't need 3g to send txts or im's nor do you need wifi. turn it on only when you need it. it doesn't make the phone any less functional. no one is saying never use wifi or bluetooth or 3g.

fact is if you want a tiny phone that is still a smartphone its not going to have a crazy battery. pure and simple. get over it and stop crying.

Responding to Bugs posting... I have a solution. Instead of turning off every conceivable feature on the iPhone, just go out and buy a 1900MaH wireless charger sold by http://www.3gpower2.com. The portable power charger is ready to go out of the box. The device will recharge in less than 4 hours and will hold a charge for 6 months. It even has a handy LED light to let you know how much charge is left. Purchase for just $38 as compared to $45-$60.

Dam everyone who complaining about this problem just jailbreak your dam iPhone and find the soulotion yourself instead Of complaing to apple. LIKE THEIR REALLY GONNA HELP YOU!!!!! THEY WANT MONEY!!!!! Once you jailbreak your phone there are plenty of battery conseverstion application that will extend your battery to limits you never imagine! For example! There's an app called SBS settings "for those jailbroken already know this" with a simple tap of the status bar, you the time and signal and shyt yea lol! It will pull down a page of all your toggles such as, Bluetooth, 3g/edge on or off, wifi and possibly everything that can me switched on and off including respring. I'm telling you once you get it set up which is very easy you will have signifcant battery improvement cause you iPhone will learn to adjust to the settings thus improving battery life when needed.

hey buy the current technology but you can use it for 10 min then carry wires/charges with you.

or turn everything off make it barely usable and then it lasts an hr.

i move the mentality behind this.

I have never had batery problems with 3G or 3GS. If anything, the battery life got better with 3.0/3.1. One thing to keep in mind: I use iPhone a LOT more then any phone before it. Naturally, the battery has to be charged more frequently. I don't mind charging it once a day or whenever I have a chance. Secondly, you have to realize that iPhone is a mini-computer, after all. How many hours of heavy usage a laptop will last without being charged?

These tips would be fine if they addressed the problem. Battery life complaints are one thing when you're using Push, 3G, and GPS all day, but when a software 'upgrade' results in noticeable and unacceptable battery drain - something is clearly wrong... and it's not a setting. Throw us a bone Apple.

By: Miles

Miles — Mon, 21 Sep 2009 20:29:41 +0000

These tips would be fine if the settings were easy to get to. I can't imagine having to go into settings and then into wifi to toggle it on and off each time I want to use the internet, it's just not a reasonable thing to expect. It wouldn't be as bad if there were little buttons on the top bar to toggle these settings.

The iPhone battery life is brilliant. The problem is how useful the iPhone is, and how that has lead to dramatic increases in usage. I've been through days were I've used my iPhone for 8 hours in a single day! I'd be lucky to use my old phone for, maybe a few hours - usually alot less. I know someone who just uses it like a normal phone, and only has to charge it once a week.

I know this would be an embarrassment for Apple, but I sure would be a lot happier if they'd let me roll back to 3.0.1 until they get 3.1.1 out. Right now this upgrade is pretty hard to defend.

"I’m not hating. I’m just pointing out the flaws that everybody is trying to sweep under the rug because they want to hail the iPhone as the greatest smart phone around. I won’t deny that it is a good looking phone and IMHO it has the best touch screen around. But, at this point that’s the only thing it has over other smart phones."

My 3GS runs beautifully without ANY tweaks. That's why the iPhone is streets ahead of other smartphones in independent surveys of customer satisfaction. And if you believe that having the best touchscreen is the ONLY advantage the iPhone has, you're living in cloud-cuckoo land. As I said, the vast majority of iPhone owners are absolutely delighted, contrary to all the negative stories that are constantly being spun on the interwebs.

@mystic... Just voicing my POV. If Apple had a product that didn't require a lot of tweaks just to run nice n smooth I would have an iPhone as well.

I'm actually amazed at how great the battery life is on the 3GS. I have 3G, location services, push notifications, wifi and bluetooth turned on all day, with the screen set to default brightness, and I ALWAYS get through the day with a little room to spare.

Bear in mind, that TALK TIME on just about any 3G phone is limited to 5-6 hours, so if you spend a lot of time on the phone each day, in conjunction with games, data or video, you're going to eat through batteries quickly. Find a way to top it up - there are a bazillion ways - or modify your usage

Having said that, I see a lot of whining on here from people who:

a) don't own an iphone b) own an iPhone and are too dim to top up the battery when needed c) have jailbroken their iPhones and then want sympathy when it doesn't work properly d) have an axe to grind against the iPhone and don't mind perpetuating a bit of FUD e) God, I'm too bored to continue.

Every time Apple releases a new phone/update we get the kind of rubbish that is written in this thread.

@Mike. Take your FUD elsewhere.

By: Mike

Mike — Mon, 21 Sep 2009 17:21:56 +0000

This is a joke....

Turn off 3G when not surfing the internet?!? LOL. Yes that makes sense but so much for shelling out that cash for an iPhone "3G" or "3G"S.

I own both a BlackBerry and an iPod and I use them simultaneously and I just keep seeing more and more reasons why owning two devices is far superior to owning one device - in this case an iPhone 3GS.

I might be wrong on this one but you FINALLY got push notifications... at the cost of decent battery life (I'm referring to item 3 in this article's list).

I'm just so sick and tired of iPhone worshippers telling me to get an iPhone when other smart phones are doing for years what the iPhone finally got after a half dozen software updates... Oh wait, there was an app for that!

Regarding this tip:

Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

I've seen two versions of this. One, as above, is to do the full battery drain down to the "out of charge" screen once a month. I've seen another indicating to go through a full charge "cycle" once a month, but never let your battery drain down do the "out of charge screen, and not down to the 20% marker if you can help it.

So it comes down to who you ask. Expert 1 says do option A, and Expert 2 says never do option A. BTW I did the monthly full power-down to the "out of charge" screen with my 3G, but not with my 1st Gen, and I'm not doing it with my 3GS. I'm not sure if it was related to the "monthly charge-down" strategy or not, but by the after around a full year of use, I was noticing significantly less usage per full charge on my 3G, as compared to my 1st Gen after a year of use.

So, in other words, you have to take your "premiere" phone on the market NOT use any of the functions that make it premiere?? My Bold would go all day without any problems, switching back and forth on its own. I could leave on Bluetooth, WI-FI, 3G, everything, and still not worry about it. Apple has REFUSED to do anyting about this since iPhone 1, and they are STILL refusing to fix this problem. My wife updated her 3GS , and now she drops 3-4% each time she sends a single txt message. That's real nice. Instead of all these OS tweeks, FIX THE DAMN BATTERY ALREADY!!!.

I've noticed that turning off WiFi does mess with certain apps (e-mail, apps that use internet, etc) pre-3.0. Same thing for location services. I'm unfortunate in that I moved out of a 3G area, and the nearest I can get to a 3G tower requires me to go 10 miles up the interstate.

Li-ion batteries hate being fully duscharged and will maintain a long life span if you try and top up the battery as often as possible. Rule of thumb is to charge whenever you can and only discharge fully when you are doing the monthly battery meter recalubration.

By: Dev

Dev — Mon, 21 Sep 2009 14:11:00 +0000

The settings this article tells you to turn off are all settings that require the phone to passively search for the strongest signals (e.g, Bluetooth, WiFi, location triangulation, email/data fetching, 3G towers vs EDGE/2G towers, etc.). All these features mean processing your phone is doing passively, without you actively telling it to do so. Therefore, it all adds up to your phone using battery power when you aren't even using it (i.e., like on a phone call or browsing the web).

This is one of the core issues of the iPhone. Why buy a phone if you have to turn everything off? In my opinion, the whole concept of a smart phone is to have everything ready at your finger tips - not to have to toggle things on/off to be able access to them. If that's the case, there's no difference between the iPhone and a netbook with 3G capability other than form factor.

I'm an iPhone fanboi, but the phone is still flawed.

I agree! i'm inside an office building and i get about 2-3 3G bars at best, sometimes it will drop to edge and not ever back on 3g until i'm outside with 5 bars. I believe that when i am inside the phone uses more power trying to get the best signal. Too bad we dont have settings to only use 3g for data only, and then switch to Edge for talk or standby.

By: YougB

Set Wifi to "ask to join"

I think the factor I notice most often is proximity to good cell towers, which is out of our control most of the time. The better the reception the longer my battery life. If I am on the interstate in a remote area, or a back highway, my battery life dives no matter what I do, due to the phone's attempts to improve signal. I can go 2 days or so around the city (major metropolitan) with regular use (talk, browse, music) and not have to charge, but after a full charge take a 5 hr car trip and its red lining.

By: Angel

Those are all fine suggestions but for a non-jailbroken phone the items listed under "Optimization of your settings" are cumbersome to access. Flipping those settings on and off all the time requires a lot of steps. There's isn't an "optimized way" to "optimize your settings".
