Apple is aware of battery life problem on 4s and iphone 4

[eddieg]

So most of your usage is from listening to music?

i still hawe an iphone 3g, and now its started to hawe some buttery issues, it disgarges in a half a day, is there any hope of getting rid of the problem or i nedd to buy a new phone?

Here is my update. Only listened to music. And light intenet browsing. No game play.

Are those numbers accurate?

On some days.

 

[sekelani]

Are those numbers accurate?

Yeah. Absolutely. Why?

 

[p3unit32]

Yeah. Absolutely. Why?

So you was able to get 9 hours usage on top of 20 hours standby?

Yeah. I didn't really use a lot of Internet browsing. Just a little bit. No game play, a lot of music. Like 6hours then used the phone for Internet. This forum and Facebook and YouTube , texting calls etc. what do you think?

Did you literally use your phone for nine hours playing music 6hrs, and the rest on the Internet, social site posting and viewing utube videos. Were you using wi-fi mostly or 3G? If so either way sounds good.

I took my new iPhone 4S off the charger at 6 a.m. Wi-Fi is on location services, Bluetooth, one email client fetching every hour, reminders, the works! Almost 4 hours left and at 35% already😔

Almost 4 hours left
I meant to say 4hrs later and I'm at 35%&#128532;

I believe I have stated all along that it wasn't a hardware issue. If you keep loading your exact backup to each new iPhone 4S they give you, you will get the same results.

That's the thing skull I didn't. I loaded everything manually. Except my ringtones.

Your report is not the norm for starting over.

So that begs the question, what apps are you running? Because your original iPhone 4S and your current one have almost zero possibility of being from the same batch of batteries or components.

Ok so heres another dumb question (This 4s is giving me more trouble than I ever had on my 3gs).

I took my 4s to Apple today regarding the battery life. The guy informs me that my best option is to do a complete factory reset. However my phone had poor battery life from the moment i opened it. Will a factory reset do me any good??

Sorry for the dumb questions, ive never had any problems on my iphones before

I know this is a several pages ago issue but I have to jump in and say here that Rocko's statements here are 91% false. I have been in the electronics industry for over 30 years and he's 'nearly' flat wrong. Even Apple makes clear of the proper conditioning of Li On battery. It's simple physics, gang. It is correct to say that you can't drain it all the way to zero that there's a circuit protecting against that potential. It's also true that the LiOn batteries of today are way better and more efficient than the ones in 20 years ago. But that's true of all electronic equipment. But that doesn't change the essential physics of a rechargeable battery. All rechargeable batteries, simply by physics, need to be conditioned. Once an initial conditioning is done between 2 to 3 cycles letting it go down as close to zero as possible, then after that it's only every so often as outlined even by Apple's own notes.

I have to side with Rokko here, i work in the mobile handset industry, have done for 15 years, tones of work has gone into battery design, and the move from Ni Cad to Li ion batteries.
Part of the company i worked for actually designed batteries from the chemical level up. And what Rocko said is true, no conditioning is required, Lithium batteries are not like the Ni Cad (which did require conditioning). The full cycle discharge and re-charge people are talking about is to calibrate the battery meter so it has an idea of how much capacity the battery actually holds, its nothing to do with conditioning the battery, that is NOT needed.

Further more he is 100% spot on when he said about small depth of discharge, the chemists who worked in the devision i managed told us that the optimal way to treat a Li ion battery is to keep it cool, and mostly if possible only discharge it to around 40% then recharge, do not perform complete cycle charges (100%-0) each time.

Apple recommends a full discharge to make sure the battery meter is accurate, by doing this once a month is makes sure that as the battery degrades slightly over time the gauge adapts to this. The whole advatage of Li ion is that is does NOT require conditioning !

heres a quote

Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life. In addition, the self-discharge is less than half compared to nickel-cadmium, making lithium-ion well suited for modern fuel gauge applications. lithium-ion cells cause little harm when disposed.
