can i know new iphone need to charge for how long???

so you guys charge daily??

mine 2 days no charge already... moderate surfing and app-ing... now 5% left

on average i charge in d mornin b4 i go to work. bout 1.5hrs should be enuf to get 100%. by the time it reaches d nxt mornin, shud b around 15%. dat is if i exclude heavy gameplay at nite after work.

how many left before u charge? 1.5 hours? damn quick!

Guys, Li-ion batteries life is based on charge cycle, reducing the cycle means extending its usable life.

It is considered a cycle once battery is depleted like say went down to 20% remaining charge...and charging it back to 100%.

To reduce the cycle, charge it when battery is still above 50%. It would not be considered a cycle if u do this and will prolong battery life.

For low to average user, charging it daily is good nuff.....how many hours u charge is fine so long as its at least 1.5 to 2 hours or more....when the battery is fully charged, the charging circuit will turn to trickle charge and that would take care of the battery n not overcharging it.

Perfectly fine to charge it b4 going to bed and remove from charge when u wake....typically around 4 to 8 hrs la.

For new iP4, the first few days of use & charge would not be accurate to guage the battery performance.....its battery can only perform optimally after a first few charge.

@yupio thanks for sharing. official data is here > apple.com/batteries

hi.. wanna ask for iphone is there any overcharging problem... coz some devices r said to cut charging when it is fully charged to prevent over charging... so juz wondering does iphone auto cut charging when it is full...

@ bruce07 read my link.

@xaw5126

Aiyah, should've posted much earlier d...save me the trouble of explaining in length on it

Thanks.

for me, whenever i leave the office or home, my iphone must be at 100% battery life !

i always thought that overcharging is bad coz....

12am - 50% left - Charging
1am - 100% full - iphone auto stop overcharging
2am - 99% - 1% was used. Since its still plugged in, BEGIN charging
2:10am - 100% full - iphone auto stop overcharging
3am - 99% - 1% was used. Since its still plugged in, BEGIN charging
and repeat....

oh well

ohh.... so if u always work in 1 day, does it mean that keep the phone connect with a powerpoint will be a better idea? the phone battery will always maintain at 100% and pluck it out whenever going out... can protect the battery wise and no need worry ran out of battery at outside =) if i wrong pls enlighten me

using an iphone 2g, lite data user n game player, but i do play games daily like 20mins average (angry birds for example), but the batt juz need to charge once every 2 days, the 3gs need daily meal (charging).. 2g better than newer versions?

Did you mean keep charging the battery even though the battery still haven't finish? I thought doing this will harm the battery. And i thought must use until finish first then only to charge the battery.

do read the link provide at previous post...
if follow the theory provide by apple, it will help to reduce the cycle used of the battery on iPhone perhaps...

hehe.. just use the way you wanted la.. by certain time.. ur battery will worn out lor.. its just a matter of time.. why so afraid.. just enjoy your phone la..

btw im just wondering if our battery really do worn out or malfuntion.. does apple cover the warranty or at least do they sell them in apple stores?

i dont think apple covered it.. but u can look upon garage sales here.. some forumers do sell batteries for iphone and provide service to replace it..

yea.. i hope they do. . btw iphone 4 is still new just afraid that serviceman now a days cant handle it so well!

yes they will cover for warranty. you can read more here: http://www.apple.com/batteries/replacements.html

any average joe who knows nothing about iphones / macs / batteries can work as a salesman at machines, so take their advice with a grain of salt.
