I have one of these:-

Takes 4 AA batteries. Loaded with four Sanyo Eneloops I can get almost two full charges out of it.

I get great use out of it when I go camping or one of my regular trips down to London. Easy just to put another 4 batteries in my pocket in a case if I think I'm going to be hammering the phone (I pretty much watch movies on my phone for the entire 3hr journey).

Eneloops are great

I can also vouch for Juice Defender (Free)

Even the free version makes a huge difference

Just downloaded the Plus version, will see how I get on. I've left it on "balanced" for now.

Nice. Balanced will give you a good improvement, but one of the strengths of JD is how customisable it is. Well worth having a poke through all the settings once you've got the time/inclination.

Any idea how I can delay the data connection like you said earlier when the screen is on?

Hmm... actually that doesn't seem to be in the latest version. :confused:

I never bothered setting it up, but in previous versions there was a slider you could set to change the delay before enabling data when unlocking. Perhaps it was buggy, I dunno, but it seems to have gone. Might be reinstated in future versions, I supose...

+1 for Juice Defender.

Had been happily using the free version up until now, but put JD Plus on last night. Seems very good to me - after 13 hours 12 minutes I'm on 71% battery, probably at least 10% up on where I'd normally be after 13 hours.

Seems to be working well for extending battery... seems to be interfering with my email syncing quite a bit though.. :S

Yeah, not sure what's happening there. I did post this response on the Essential Apps thread, but it's got lost amongst keyboard discussions

:

So, your email syncs ok without JD active? Do you have it set up as push or set to sync at specified intervals?

You can change how often JD switches data on to allow syncing with your accounts, but 2 hours is the maximum so that shouldn't see 6hr old emails not syncing. Unless you were out of data range during the times it turned the data on, which I guess is possible.

Have you got "Schedule" enabled in JD settings? I think if it's disabled it won't turn data on at all when the screen is off. When it's enabled, you can set it to allow data connections every 5m, 10m, 30m, 1h or 2h.

Thanks!

I've left Gmail as default so I pretty sure it's set to push. Without JD I would get an email not very long after sending so it seems like it must be.

As for Schedule.... I'll dig around in the settings but I suspect you're right with it just not allowing data connections at all while the screen is off. I'll do some digging but don't remember seeing that setting as I'm on "balanced" and left it at that.

EDIT: I can't for the life of me find any sync interval settings in my gmail so assume it's just on Push.

Enabling this has fixed it - thanks!

I wonder how this works btw, is it on a per-app basis or does it queue requests from each app and let them all use the data connection in a batch?

I don't know, tbh, but think it just turns on data for 2 minutes every x minutes/hours, and the apps are then able to update. Not sure it does anything in terms of queuing apps data requests, mostly because that just sounds really complicated. I presume the apps themselves connect as soon as there's a data connection if the specified sync time has passed (?)

One other thing you can do in JD, btw, is to let it enable it enable or disable connectivity when specific apps run, regardless of the wake/sleep state of the screen. This means you could set it up to let, say Facebook sync when it wanted to even if data was disabled by the screen state. I've not bothered with that, but it's another layer of options to tinker with to get it working just how you want.

Glad you got it working so far, anyway.
