sure got mate..its a fact..when the apps is not exit/close properly it will use ur battery at the background..u will see the difference when u properly close the apps before locking the phone...

geezzz , out of sudden standby time = usage time. I tried to solve this problem by choosing "Reset all settings" and the problem will temporary solve, but the problem will be back after 2 days , not sure i already reset my phone for how many times d , maybe more than 100times, do let me know if there is any better solution, Thanks.

try reboot it
it's a random incident
i oso experienced it too....

n after google for this solution still not found any concrete formula to solve this...i guess we need to wait for ios 5.

i've experienced this problems for past 5months on my i3gs from 4.3 to 4.3.3 (usage time=standby time), so far i still cant find any solutions to solve it. I've tried turn off all the those notification, location, 3g,.... bla bla.. try restore 4.3.3 by download it from different sources, deleted microsoft exhange account from iTunes and i3gs, jailbreak it using different version of redsnow............but it just cant help. No matter how i restore it, it will trigger back this prob. The only step that i hvnt try is to update it to 4.3.4/4.3.5 cos there's no untheter jailbreak.

there must be some bug to trigger it, as my friend using I3gsm 4.3.3 jailbreak using same version JB tool but he nv encounter any prob like i do but i still cant find the solution.

agree...it should be bugs problem but yet they didnt know which jb tools cause to this issue...

i think facebook app might be the culprit

just now went out after 1 hour after full charged

and I only use whatsapp and fb

however after a while my battery kinds of like draining faster

thou I cant check the usage time because I only turn on notification after some usage after 100%

u left ur fb running on the background??surely this is the reason for it..now u see the improvement of ur battery rite?

no i always terminate it... each time i open

it's like a random occurrence

mayb there's a difference between terminate the fb 1st and off notification later

and off notification 1st and terminate fb app later

u r rite mate, im notice the difference when i sign out n killed fb without turn off notification 1st...surely this is the reason for the battery to drain faster than before...

need some people to help verify this thou

i'm not sure bout this culprit but it doesn't work for my case. Even i sign out and kill the apps straight

maybe the result of it will differed if using iphone 3gs??

Can i charge my iphone when its 50 percent or less? or i should wait when its 20 percent and below only charge?

sure u can mate.its not effect the battery life...

remove your simcard & put a different simcard with a different carrier back on....

is this method really works??

works on my ip4 everytime..........

This is the final solution for me! It works 100%

yes finally this solution work for me. But i think is a only for temporary. Let see..
