Nokia Lumia battery charging issue
Discussion
Just recently my 1520 has started behaving very odd with regards to charging.
If, on occasion, the phone does recognise that you have plugged in the charger then it will begin charging. However, at some random time later it will stop charging. Then you will hear a small vibration, just like you get when you plug the charger in (to acknowledge the charger) and it will begin charging again. Often, this will happen numerous times in quick succession, like you are repeatedly unplugging and replugging in the charger like an *****, except its the phone deciding to acknowledge.re-acknowledge the charger.
Additionally, when it does charge for longer periods of time instead of the charging rate climbing linearly to the usual maximum of about 25%/hr and then remaining there until full (this is checked with a battery monitor app called battery and this is how it used to behave when I first got it) it is very erratic, spiking up or down between different charging rates seemingly at random.
On a few occasions now the phone appears to actually discharge by 3-5% shortly after plugging in, before it begins to re-charge. That one is baffling I have to say.
This is the second 1520 I have had after my first had terrible screen backlighting issues. This one now seems to have charging issues. The phone doesn't charge at all in the car using a 1A cig-lighter to USB plug so I don't bother anymore (not that I use it at all frequently in the car). Also has the annoying screen touch issue where it records scrolls as taps.
Anyone got any ideas what could be causing my charging problems and what I could try do about it? I am thinking of using a slightly more stout charger to see if thats the issue, the iPad charger is 0.5A stronger and its a much bigger, more robust looking thing. The Nokia 1.5A charger seems rather too lightweight. I may also try signing up to the dev preview and get Windows Phone 8,1 on there (They are taking far too long with that, why announce in early spring only to not actually be ready at all>?) and see if that has any affect.
there is a screen shot, at the point the Nokia charger was plugged in (the only charger outside of the 2 times I have used an in-car one) the phone discharged, then began charging with this erratic charge rate. I had to intervene once as it had stopped charging and would no longer recognise the charger being connected. After the second time it just stopped, I switched to an iPad charger (in yellow) and so far, normal service is resumed. As you can see, nice linear ramp up to a plateau of 15%/hr, some 10% down on what I normally saw with the Nokia charger, but I don't care so long as its predictably going to charge.
Perhaps the nokia charger is simply being over driven or running too close to its limits? Normally it would power along at around 25%/hr.

I am unsure. I charged it today via a normal USB port on a computer and it was fine. Charges much slower because of the 0.5A the port supplies, but otherwise it charged without issue. I will use the bundled charger again tomorrow night to see if I get the same behaviour.
There are a few reports of dodgy charging on the WPcentral forums regarding this phone. Nothing exactly like this, but lots of reports of slow charging or not detecting the charger supplied with the phone. A soft reset can fix the latter, along with the annoying touch screen issue (where an attempted scroll is detected as a tap), but who wants to keep turning their phone off in order to get it to work?
Similarly there are reports you must use the bundled charger only, though in my case it appears the bundled one is dodgy. The iPad charger and computer charging worked absolutely fine. Anyway I though the whole premise of the EU forcing manufacturers to stick mini/micro USB connections on phones was in order to cut down on the amount of chargers that are made and subsequently become useless. Any phone should be able to charge using any USB style charger without issue.
