Why is my iPhone charge going down while it's plugged in?
My iPhone's battery charge is going down while it's plugged in to my car charger. It only does this while I have the Maps app running, and as soon as I close down the app it begins to charge again.
I use this app fairly regularly and haven't had problems charging and using the app at the same time until now. Is the GPS app somehow using more power or is my battery faulty?
Is this a good question?

Quick update. Cleaned out USB connector no improvement. Will open it up for a look when I get the chance. My phone is getting rather warm at times though. Especially when running particular apps(maps and games).

Phone sometimes does get warm using these type of apps. I'd check the battery with a multimeter.. Should be 3.7,
any drop/damage to phone?
have you checked the charge cord itself?

Little bit of an update.
The phone has started coming up with a message sometimes now when it's plugged into my car charger every now and then:
"this accessory does not support charging" or words to that effect.
I tried searching ifixit for it but no-one seems to have posted anything about this. Does this give any clues?
ps. I haven't got round to opening it up yet but i did clean out quite a lot of crap from the dock connector.

The search function on this site only works if people put tags in... but there may be more answers under the search dock connector?? anyway I'd give the dock connector a very thorough clean. get out a small paintbrush and really clean! it may need something like isopropyl alcohol to get ingrained dirt off the pins. (turn phone off first and disconnect logic board from battery)If that doesn't work and the battery isn't draining, I'd just put up with the alert. Ours has done that with a bose dock since day 1! Do your problems only happen with incar charger??

What kind of car charger are you using? I had a USB charger that didn't deliver enough juice and my iPhone would charge and then not charge. Finally had to get rid of it. But I seem to remember a message similar to the one you describe also periodically coming up.
