The User's Guide states that a 5V, 500mA micro USB adapter can be used for charging. Chances are, any recent charger made for fast charging phones and tablets is rated much higher, from 1000mA up to around 2500mA. In principle this should not be a problem since it's not what the adapter can provide, it's what the device will draw. If it wants 500mA then it will pull 500mA regardless of how much the adapter is capable of providing.
In practice, cheap, no-name wall warts are junk. The power they deliver generally is not well regulated (choppy, spikey) and they are more likely to short out and cause permanent damage than reputable brands like Amazon and Anker. If you have a genuine Samsung charger then it should be good (I have two and they've exhibited no problems with any of my devices).
Also, it's been demonstrated that USB wall warts can be used to inject malware into devices being charged. I'm not saying that this is the cause of the unexpected data connection pop-ups (my ONE sometimes does the same with my Surface Pro's charger for no apparent reason since it's definitely power only) but it's certainly a possibility.
As for battery life, if you've installed firmware 4.1.x then you should have reasonable battery life. IME, maybe 5% drain while idle over a 24 hour span (that's an off the cuff figure; I haven't measured it). I found that I needed to perform a factory reset before installing 4.1.x. If you're using a sleep cover then you need firmware 4.2.8110.

I am using a certified LG charger now, although it delivers 1 amp, but as you said, it is not like the charger pushes the charge, but that the device pulls it when it needs it.
The idea of hacking a device via power grid is interesting, i know there are Ethernet replicators distributing LAN across the home using wall plugs as outputs, so technically it should be possible
I got mine KA1 a day before the 4.2.8110 has been released (seller told me, he has updated it, so it came with whatever version was previous) and i immediately updated it via Kobo app to the latest.The battery drain shouldn't be caused by firmware. I charged it the day before yesterday (at 10 PM it was charged), i have been reading till 2 AM, yesterday i have been reading almost whole day - like from 10 AM, till 12 PM -, with max. 2 hours pause and today i plugged it in again with 10% left... so i think the battery just needed a calibration as it lasted more then a day with frontlight on most of the time.

yeaterday having waited weeks to find a store that had one.
There was a dark shadow around the margin area of the screen. Phoned Kobo and they advised a factory reset. This lightened the shadow but it is still there. Phoned Kobo again and was advised that I would be contacted by a higher level...... but I'm still waiting.
Has anyone had or have this problem, I can return the Kobo to the store for a refund but they don't have any more in store.

My KA1 has just a little lighter stripe on the bottom of the screen caused by frontlight + the colour of day light isn't completely equal across the screen, but the difference is minimal, unnoticeable when you don't directly search for it. You should probably return it.

Also, you need to know that you need few full charging to reach full battery capacity (it looks like you didn't do full charging from your description, so try to fully charge battery, at least now in the beginning). |
The bug report is interesting, mainly the fact, that the KSM is running in the background all the time, so probably it checks for inputs and drains the battery a bit.. as i don't see any advantage in the KSM, because i use it only as a hub between Nickel and KOReader, i will probably get rid of it.
I will try to calibrate the battery by full charge/discharge/charge cycle
thx
(sorry for the long post xD, although this a forum about reading, so you should be ok with it
)
