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?

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).

による

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?

による

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.

による

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??

による

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.

maps app uses triangulation off cellphone masts... basically it's a huge battery drain as it's sending/receiving signals constantly...

It shouldn't noticeably drain your battery when it's plugged in to mains/charger though. It may be that your in-car charger isn't delivering enough power to compensate-I'm not sure what the output of in-car chargers are.. I'd start troubleshooting with the charger/USB connector; look for damaged pins/wire/dirt.

My phone battery gone down while I'm otp and it charging I didn't have this problem until now. If it's on a low percent it goes down and up but not as much. Is the problem my battery or charger

による

Otp means on the phone

による

Okay mine used to do this

You simply have to get a new charger

I bought a new charger and it works if yours doesn’t work after that get your battery replaced

による

you might have downloaded an app/game that takes huge amount of space and have very high graphics. If so, delete it and try to charge your phone again.

WIFI or 3gs connections are heavy drainers of the battery. You have not mentioned what firmware/operating system is installed on your iPhone. Also if it is unlocked and jail broken. Have you tried restoring your system since you noticed this happening? You would be amazed at how many bugs that are fixed with the iPhone by doing that. You have not mentioned anything about the battery life during normal use. If the battery is on the way out it will lose amperage capacity. Amperage is the electricity. Voltage, in essence, is how fast it is moving. Please tell us more about your iPhone and your attempts to resolve the problem.

GPS uses a lot of battery. Depending on the car adapter it may not be generating more than it's using. Also I agree that if the battery has been run dead too often it will cause the battery to charge more slowly~or at all.

Sounds like the battery is not taking the charge any longer. Some batteries, when they have gone completely dead, then they are DEAD and you have no choice but to replace it. Another reason is that your charger had died and needs to be replaced.

Change your setting to turn off the device when battery reaches 2%. When the device turns off, you'll know it's time to recharge.

It's a falty charger you don't need to use the original lighting cable and wall adapter but you do need to switch or it could cause permanent damage to your phone. If you have other lighting cables I would recommend trying them first it could be the lighting able or the wall adaptor as apple wall adaptors don't last long. But anyway switch them now because this could cause very bad battery issues down the line.

I need help. My Iphone 6Plus wont charge while its on the charger. I cleared background running apps before it died. Everytime it gets to the apple screen it dies again sometimes it manage to get enough power to the lock screen and I was able to cut the wifi connection off but I wasn't able to put it on low battery mode, I even cut on air plane mode to help it charge faster, but it keeps shutting off and shutting on up until the apple pops up. it wont go any further than the lock screen and within seconds its dead again. Please help me. I really need my phone.

Well this is problem with your charger in most of the case. I replaced the charger and now it works fine. But this is very probable to repeat again with this new charger too. USB charging and charging with new charger are working for now.
