I was checking Apple Maps on my iPhone 5 at 5% and it suddenly died. I was in the street about to go somewhere so it really ****** me off. On top of that, nobody could help me in stores or bars because everybody has the old connector to charge it!

 

When I arrived home I plugged it in and in a matter of seconds it came back at 5%.

 

Any solution to avoid it happening again?


iPhone 5, iOS 6.0.1

    Simple solution, do not run it down to 5%.

     

    Draining a lithium ion battery completely is not good for the battery.

    I didn't expect that answer... I use my iPhone to work on the road and some times I don't have the chance to re charge it, so I depend a lot on a good battery.

     

    Everytime I can I follow all the tips to improve battery life, many of them ridiculous (i.e. do not use LTE or location service!!!).

     

    In this case it wasn't that my battery died: the phone unexpectedly died and as soon as I plugged it it wen't back to the original state of 5%. It's the first time, many other times I've used the phone with 3%, even 1%, especially once a month, to run it to 0%, as recommended by Apple, and never had a problem.

     

    That's why I'm asking if anybody experienced the same, and if there's any tip to avoid it, like reconfigure or reinstall or something...

     

    thanks for your answer anyways.

    The battery readout is not 100% accurate. To make the battery readout more accurate you are advised to charge the phone to 100%, then run it down until it cuts out, once a month or so.

     

    If you are on the road a lot, why do you not have a range of mains and car chargers to hand?

    Try fully discharging (until it shuts off) and then fully recharging (don't unplug until 100%) to recalibrate the battery meter.  You may need to do this a few times.

    The iPhone does not let the battery drain completely... it shuts off prior to that, i.e. 0% is not 0 volts.

    I already did it a few times and two days ago I was again with 5%, I turned it off to save some battery and I couldn't turn it on again!!!! It asked me to plug it.

    Like tonefox said, the meter is not perfect.  That being said, you may have a battery problem.  It's still under warranty so take it in and let Apple look at it.

    Because I travel by bus

     

    Also, because manytimes I have to be in the street a lot and I have no time to look for cafés with power supplies. What turns me crazy is that the two times my phone dies at 5% I managed to find people with chargers, but the universal one, not the new iPhone 5 charger
