My 3GS suddenly shuts down when the battery is around 30-40%. Only happens when I'm using something, eg. Safari, apps. Anyone experienced this? It started when I updated to 4.3.3. No problems with 4.2.1

mine even classic 80% around oso can auto shut down
and when i use
can direct reduce 10-20% battery level

im planning to get new battery
kinda like dying

had no problems before 4.3
working gd in 4.2.1
after 4.3
all the nightmares came

Hi Guys,

I think I m experiencing battery drain as well. Normally i charged my phone fully before I sleep that will be about 12am...

Then whenever i get up..i should still have about 97% at 6am

However, nowadays I only have 93% despite turning everything off.

And on average day time with hardly any usage, my battery drains at a rate of about 7-8% / 2 hours....is that normal ?

HI coconutron, hows going? Standby mode dropped 3-10% I would say its normal wor. But your day time usage is abnormal. IOS 4.3.3 might be the culprit after all. I'm experiencing the same thing myself with my oldie i3gs.

Yo bro!!! ya lor...it only happened recently ...sighzz...wanna send back into maxis also problem la..no replacement phone...sighzz

Sean also facing the same problem? Dunno whether to change battery or buy an external batt. But the problem only occurs when I'm using apps. Maybe wait till I go overseas then go to an Apple store and ask them to check. If got problem then I'll probably change it.

yes
i already changed the battery just now
going to use for few days
and see if the problems occurs
if happened to me when I safari /fb/ game/ beejive/ twitter/whatsapp

Where did you change it? How much?

Penang, for RM95

Anyone knows how much will it cost to change battery at Maxis/DiGi? Just asking to see whether it's more worth it to change at Maxis/DiGi, Apple Store overseas or at a local handphone repair shop.

i don't think maxis or digi offer replacement of battery...normally if ur iphone is still under the warranty period they will replace it with the refurbished unit...if ur iphone warranty period already end just go search for a professional person who can replace the battery with a new battery...try search it HERE...

hows the result?

i encountered the same problem.. but i think mine are more weird... after sync.. my battery works ok.. normal lor.. can use for the whole day.. but if i didnt sync it for quite some time.. the battery will act funny.. half day almost finish.. thats weird rite.. haha

Yea, I searched already. Yezhacolic is charging around rm90 I think. But not sure about the quality. It will cost $80-90 in North America though. Waiting for Sean to give comments on the battery. From what boblp said, I'm not that confident in the quality.

me also having the same problem any solution??

so far quite gd
can definitely use the phone every function ( haven try GPS)
at battery % where I've long din reach b4
feel so satisfied

will try to calibrate it later
then monitor the usage

I noticed that if you turn off the WI-FI, the battery last much longer
