But if you don't mind, the Sanyo Eneloop Mobile Booster KBC-L2AS is good, cheap and has 5000mAh for a portable charger.

There's a forummer that brings in this product.

off the 3G and all push notifications and u will see improvements

What I am trying to highlight is that even if left idle... it could actually drain 15% when a few days ago it only drained 3% with the same settings.. which is very peculiar

try restarting the phone 1st

there's an issue where some apps are still running in the background even if u already quit it. particularly those apps that isnt updated for ios 4 yet

my battery 94% .. when i respring it goes back 97% .. o.0

respring?
now 14 hours 30 minutes idle
1 hour usage.. 87% left... seems ok

I believe its a new phone right? Lithium-ion batteries takes a few charges to get to its peak performance and later deteriorate as it ages

Try This out Friend:-

1. Turn Off Push:
Change your email FECTH time so it’s less frequent or turn it off completely by tuning off “PUSH” and check your emails manually, This can save around 20% battery life.

2. Turn off 3G if not in use:
If you don’t see a 3G icon on your iPhone status bar, then you’re not in a 3G hot spot., and you’re not getting any benefit from the phone’s 3G radio. By turning it off, you’ll double the length of your iPhone battery power from 5 hours of talk time to 10.

3. Turn off EQ:
Applying EQ settings to your iPhone apparently drains extra battery. If you’re planning on keeping your phone alive all day, turn the EQ settings off.

4. Set Auto-Lock to 1 Minute:
When you’re not using you phone, lock it. And just in case, put you iPhone to the shortest possible auto-lock setting so that it locks automatically (and quickly) when you aren’t active.

5. Turn down screen brightness:
When you’re in battery life saver mode, turn the brightness all the way down, it doesn’t take a genius to understand that more brightness = more power consumed.

6. Minimize use of location services:
Since this requires the use of GPS, using location services sucks more energy from you battery. Use it only when really necessary (that means don’t go on MAPS just because you’re bored).

7. Turn Off Vibrate in Games:
A lot of games have very frequent vibrations, which drain battery life. If you can, turn them off in the game’s settings.

8. Stay updated with the latest firmware:
Apple’s minor firmware update frequently introduce some new methods of functionality which are better on battery life.

I left my phone fully charged at 5 am and i did restart my phone because at 6 am, battery decrease to 96% in idle. Now at 1 pm, battery already 73%. why suddenly become like this?

i bought my iphone during maxis launch. my setting everyday when im at home: cellular data ON, 3G OFF, Wifi ON, Notifications ON for facebook, whatsapp, game center. email push OFF. brightness around 50%, location services ON. firmware iOS 4.1

hmm.. ur cellular data is on.. most of the apps will try to cnnect to the net.. maybe thats the problem

assuming u've done all that ahmadcivices01 posted, i guess i'd be worried too. do u use foursquare or twitter? these are the apps that genius bar claimed can't quit when my friend had the same problem

i leave cellular data on all the time, it doesnt drain battery a lot

i use this setting everyday since i bought it. y today only got problem?

Is a common problem. The recommended solution is turn off 3G when is it not in use. Minimize the usage of WiFi.

Hi guys I may have an issue with my ip4 battery life
but not sure.
Charged at 12.30am unplug from charger 7 am
Started using 7.45 am.
On 3G , was on twitter, Facebook ,watched 2 you tube videos
and checked a few mails
At 8.15 am I am down to 93%
Then 3G on and idle till 9.10 am down to
90%
Always kill all processes after use
Brightness set to half with auto brightness off
I am on latest 4.1
Is this normal or do I need a dreadfull restore??
Please advice friends

hey bro I've actually face this problem as well, the first month was awesome, on wifi and all and the batt don't drain as fast, but all of a sudden 1 day the battery starts draining like crazy, and it's gonna continue in this manner (at least in my case). I tried and experimented with many many ways to keep my battery lasting as long as possible (after this happens) and found out that the 1 that's draining my batt like nuts is wifi, (btw i have cellular data and 3G both off). i even turned off push notification and manually close all the apps running in the background, but batt still draining very fast, only after i turn off wifi then the battery starts to go back to normal. hope this helps, u can try it out urself..
