Well, after buying a Ravpower battery and going on my trip I'm very disappointed to say that they've all failed - one of the Anker units swelled as has the Ravpower one and the remaining 2 Anker ones randomly shut the phone down, and not just when they're running low either - it's happened when the battery is at 90% at times!
Anker have zero stock so issued refunds and I'm waiting to hear back from Ravpower but a quick look at their amazon.co.uk listing shows that they're out of stock here in the UK.
I'm in need of at least one fully functioning battery to test the phone (I've installed a different ROM to be sure it wasn't a software issue or rogue app). The only non generic one I can find is
this - has anyone had any experience with them?
What about any other options - with such an active note 4 community, surely we're all in need of new batteries at some point - what do you use? (I don't want to spend £35-40 for a new Sammy unit on a phone that cost me £150!)
