[Nexus 7 Android Development] Andy2No:
I've been using cheap USB power meters with my chargers, lately, so I can see the current and also know when it's finished, or getting close. It's quite possible that upsets the devices being charged, of course.

The best I've seen, recently, with the Nexus is 0.53A, according to the power meter. I found my Apple chargers work better than the official Nexus one. The older one, that came with my 1st gen iPad gives the most current with anything (typically 1.2A with my iPad 3), but either Apple one gives the same 0.53A or so, with the Nexus and the same cable.

The cable can also be a factor, of course. I've assumed the official Nexus one is a good one, but I haven't done any testing - and they can increase in resistance with age, due to bending the wire.

For my usage, it's not a problem so long as it charges eventually, and I can use it while it's charging, but there does seem to be an unnecessarily low limit, yes.

It was the same with the last couple of ROMs I tried, which were both versions of Lollipop. I didn't really pay attention before I started trying new ROMs, not long ago, because I wasn't finding uses for it any more. My interest in it was revived because Lollipop and above let me use my cheap Behringer USB audio interface, so I can use it as a spectrum analyser or half assed audio range oscilloscope. This ROM lets me do that while it's charging, which seems promising too.

There are quite a few free apps that can do it - you need to be rooted to use them, of course.

I couldn't find one that worked by taking over the power button, but there are plenty that give you an advanced reboot menu, started up as a normal app. I settled on one called Reboot (version 2.0.5) by Pierre Sagne aka Petrius. I got it from the Play store, in the normal way. His website is freaktab.com.

It gives the same options I had on the last Lollipop ROM I tried (a Ressurection Remix something... sorry, I forget the details). It works fine.

Thanks :) I looked for the setting and couldn't find it. I was sure I'd seen it before too, but it wasn't where I expected it to be. I didn't think to look in Location, and I wouldn't have though to press the three dots either - which only gives that one option, so it would be better if they'd just shown it in the main list of settings.

Yes, that works for me - at least so far. I'll try to remember to turn off scanning after use. It's an extra step, but it's easier than rebooting. It seems to be okay to turn if off again immediately after connecting.

... I may have spoken too soon. I thought I'd managed to turn scanning back off, then on again, and get Wifi to reconnect, but I can't get that to work now. It looks like you only get to do the trick once, per boot, or maybe you can sometimes do it more than once, but not reliably.

Turning scanning on and leaving it on does seem to let you disconnect WiFi and reconnect as often as you like between boots, but I'm not sure I'd want to leave it on.

Battery life is what matters most, to me. This ROM reboots pretty quickly, and I'm not a frequent WiFi user, so I may just settle for leaving it as it was, until there's a fix.
