[Closed] Which smartphone with replaceable battery?

Any phone with a USB power pack. The bigger ones are good for 5 or 6 full charges. You can just leave it pugged in all day and won't need to power down at all.

Any phone with a USB power pack.

That's what I do. I have the phone bar-mounted and for all-day rides I stow a battery pack in a top-bar mounted tribag and run a short lead to the phone.

Means I always finish the ride with full charge.

If you were happy with it, another xperia neo?

I don't know if they are available for android, but the battery case for my iPhone will easily manage a days ride and have plenty of power left

External USB battery as said. Good for all your toys then - and cheaper than most replacement batteries.

I used to have a htc one x excellent phone just poor battery life. Ive now got a galaxy note 2 which lasts 2 days without charge as the battery is very high ah and its removable so you can buy even higher ah batterys off ebay. Ive heard good things about a motorolla which has a very good battery all above are android with usb as the charging point.

USB power pack sounds perfect. I hadn't thought of that. Got any links to recommended ones?

Running Strava/GPS on my Motorola RAZRi doesn't seem to have a big effect on battery life, I can do 5 hour rides and still have 50%+ battery left if I leave home with a full charge.
To the OP are you navigating with your phone or just logging where you've been?

There's a number of high capacity power-packs available through Amazon, the TeckNet iEP380 5000mAh one costs £16.97, and will charge anything, and it has two USB ports as well, so you could charge a pair of small external speakers at once, or the phone and another device at the same time

How weatherproof are the connections between these battery packs and the phone - or is it assumed that they are safely ensconced in a waterproof bag somewhere?

As for the phone take a look at the Samsung X Cover 2.

Its waterproof and rugeddised for drops and knocks. I just got one to replace a Motorola Defy and I'm very happy with it. Unlike the Mototola its actually a pretty decent smartphone as well as being a bit tougher than normal

How weatherproof are the connections between these battery packs and the phone - or is it assumed that they are safely ensconced in a waterproof bag somewhere?

Well, obviously they're not proof against it pouring with rain, but the assumption is that phone and battery will be in a pocket, and if you use a fairly long lead, and are careful, there shouldn't be any more issues that you'd get using the phone on its own in iffy weather.
If you picked up a 2m lead, you could have the battery in a backpack, and the phone in a jacket pocket, for example. My battery pack doesn't come out that often, but its been very handy at times, and I've used it for charging my camera's batteries, using the lead that plugs into the camera itself. damned useful thing, no home should be without one! 😀

I take the opposite approach to the Count.

Phone on bars in waterproof-mount like this:

Which accepts a lead like this:

via the shortest right-angled usb lead I could find on ebay (~20cm) to one of these:

with one of these in it (sealed in a freezer bag for extra waterproofedness):

Works for me.

Neat set-up that, Graham. I never bother having the phone on the bars, and I'm usually out walking rather than riding, but I do like your solution, very compact.
