Reset the settings. If it doesnt work, upgrade the firmware to latest. *since ive read that her phone isnt jailbroken so i assume she wont be jailbreaking it*



I used to had same problem butt..my phone was jailbroken. Found out that some apps that uses wifi made my phone overheat if left on in the background too long.


btw what firmware is ur wife iphone on?

I just restore the Iphone 2g firmware and Unlock Only using Redsnow.
I shall see the performance of the battery.
And those 3GS guys,i will update also on this.Let me check my GF phone.

Just few days experience using iPhone4. Everything is fine, the only one thing is the battery, i need to charge it everyday. I tired to turn off Wi-Fi, 3G, Cellular data, auto-brightness, the battery is still finishing fast.

it was about 90% last night before I sleep, then morning til now oredi 65%. this morning, what i did are MSN (using 3G), send few SMS, answer one call (30sc) only, use few apps (not game) No FB and safari. Is this normal?

As far as I'm concern, her firmware is latest but I'll ask her to reset the setting and see whether it would solve the problem.

ip4 color is retina display woo~ normal if take 1day then u need to charge back..

mine also..chrge exmple 6am finish..8 or 9pm need to charge back (wifi 24hours, sometimes 3g,call+sms,fb,twitter,ym,foursquare etc)

maybe u can read here more better

Fix your brightness settings. Auto-brightness drains battery as well.

Lastly, double tap home button to bring up the multitask bar and remove all running applications before you go to bed. You can conserve battery that way as well.

Also charging everyday is pretty normal at most for me I can get 1 1/2 days with about 6 hour usage time.

weird. today my battery drain so fast. full charged 100% last night at 1am.
wake up at 7am, battery already 70-80%. now only left 7% with 2 hours total usage. Wifi on. 3g off. no running apps. brightness 50%. before this happen 1-2 times. now it's happening again. weird.

reboot ur phone

but sometimes, even though I reboot my phone, it doesn't solve the prob. I need to wait for the battery completely drains and recharge back. then the prob is solved.

try turnin ur wifi off. coz my bro had d same prob. batt reduces 1% every 2min while on sleep mode. wifi was d problem.

my i4 charing 95%-100% need takes 30min...slower than 1%-94% alot...is that common issue ?

yes it seems normal, because after 80% the charging will change from rapid mode to ripple charge mode, something like that, read it on apple website.

meaning a full charge will takes 4 hours?

mine's not that long, about plus minus 2hrs full charge from 2x%.

hi all, 1 noob question please . everytimes i charge my 3gs until it show battery 100% then i off the charge. is this correct way ?

Its very subjective thou, based on experience wall charger usually perform a faster charge comparing to USB cable charge.

No need unplug is also possible yo, Apple battery is rechargeable lithium-based, it will automatically stop charging when it reaches 100%. So chill, leave it there or unplugged, either way is fine.

Ic. Thx. I noticed charge 2 hours will 100% fully charged

guys,do you think its time to replace my iphone2g battery ? 3 years already with that battery.
what i notice,after battery full drain,when charge,its take about 20min only for full bar.then later make call about 10min its automatically will switch off the phone.
If full cycle charge (about 4 hours),i will reboot the phone.
So after make call about 10min,Sms about 15 within half hour the battery percentage about half.
So do you think can i change the battery now ?
So will that be just like normal battery ?

Congrats me...I have this problem but I'm more worst...1am 100% 7am wake up left 35%...Background only setting another apps is running only...Haiz just 1month + use only seems like getting more and more problem out....I will reboot my phone hope wont happen again la....

Pass few days my phone batt draining quite fast as well. Previously was okie, even I rebooted my phone still the same.

Wonder is there any Apps cause the batt drain. Nothing running on the background but still drain quite fast.
