Alright I already went over all the possible ways to conserve battery life on the iphone 3gs... but I want to know what is best in terms of charging in...

1. Should I always "cycle" the battery? (Charge to 100% and let it drain fully) everytime?

2. Or can I do partial charges and not have battery lifetime effected?

3. Or suggest another way.

P.S. When I close an app (press home button to return to home screen), does that completely close the app to preserve battery life or is there a technique i need to do to ensure the app is completely closed?

im also wondering about all these things
 
Once a month let it totally drain then fully charge it up, this keeps the battery icon accurate. But the rest of the time just give it little top ups here and there.
 
Hold the Top Button (Sleep Button?) until the red "slide to power off" (too lazy to check what it says) and hold the Home button.

I think it clears up RAM? Idk it does something haha

Buy a charger for your car/work-home so one is always close by. I have one for home, work, and my car and charging is rarely a problem.

I turn 3G off unless I am browsing and Wifi off unless at home. It helps

no, with 3G off the phone reverts back to EDGE. you can still make/recieve calls and texts, and use the internet.

Are there any utilities or apps that turn 3G back on when you use Safari or another network application?
 
Unless you are using the phone crazy amounts, there is no need to do anything special.

Charge it at night, use it all day. Other than this, the battery pack on the 3G and 3Gs should not be dischanged or treated specially.

I use my phone as an alarm clock (so I only charge it for 3 h every night) and use the iPod app most of the day with moderate data usage. I typically have 25-50% battery life left at the end of the day.

I have push enabled. I have WiFi on. I have 3G on.

The biggest thing that affects battery life is the amount of signal you have. Anything less than 2 bars will drain the battery life very quickly.
 
Li-ion batteries should NOT be fully discharged if it can be avoided. They perform much better with frequent, short charge patterns. So don't needlessly discharge your whole battery just for the sake of doing so... once you get down below about 20%, you're beginning to do harm to your precious battery.

However, it is recommended that you DO fully discharge and completely recharge your battery just once after every 30 full charge cycles (probably around 45-60 days, depending on your daily usage). This simply allows the battery charge sensor (the gauge) to keep itself properly calibrated.

Lastly, heat is an Li-ion battery's worst enemy. Keep it out of direct sunlight and preferably out of thick silicone cases, which insulate the heat generated under normal operating conditions.

Seriously, that's all there is to it.

It would be nice if you could post a source for this information. Anyway, your 1st paragraph seems to conflict with your 2nd paragraph. Or are you just saying not to discharge the battery too many time during a month of use and that is okay if you only do what you wrote in the 2nd paragraph.

Since this is such an important topic, I wished they'd post a sticky on the proper way to charge the battery for the iPhone.
 
Bump for this too cause there's been a lot of conflicting opinions on this issue. Apple also recommends to do the once a month full discharge cycle, but this is the same apple that sells you a phone with a non-removable battery...

Source? I've never read that it does damage before :confused:
