I remember once when I was roaming at exhorbitant cost, I was regularly turning off data to save money and my battery life was greatly improved. I wish I could have finer control on the polling frequency and volume of most apps...

It should be doable to build an Android app that turns data on every X minutes. Does such a thing already exist ? Does it really help with battery ?

Tasker can do it, but it might require a rooted phone to be able to toggle the mobile data setting.

Can we talk about the Nokia 8210 candybar phones? Circa 1999 this thing was indestructible and had battery life that would probably outlast 3-4 iPhones.

I think there is a market for these types of phones again. Even if it was ugly it was durable and functional. There is definitely a market for a phone that can be dropped and still function.

Batteries that last a week would be nice in current markets too! Not just emerging ones. I personally still don't understand how flagship phones costing $100s barely make it through the day but still get rave reviews. I can't count the number of times Galaxy and iphone touting friends have become unreachable in the evenings because of this - I would have trashed those in a review, who cares about fancy features if yo…

Quite simply because longer-life phones would get trashed even more for not having the features they traded to get longer battery life.

Imagine what the reviews would be if the next iPhone is twice as thick and double the weight. That it goes 3 days without a charge for most people would be a footnote to an otherwise poor review.

Personally, I tried to get it to do a "turn data on when I have the display on, otherwise turn data on every X minutes/hours", but handling all the corner cases was difficult.

Plus, programming in the Tasker UI is fiddly.

Yes, and yes. https://play.google.com/store/apps/details?id=com.gyagapen.c...

It essentially disconnects data when screen is off (the algorithm is a bit more complex, but that's the basic idea). Especially in areas where my phone passes between 2G/3G/noSignal often, I see much improved battery life.

According to this [1] StackOverflow answer there is no API support for enabling/disabling mobile data, but it can be done using reflection. Process requires CHANGE_NETWORK_STATE permission.

I just bought a Nokia 105 for about $16 after my 6320 finally died, and I'm quite happy with it.

Battery lasts for ages, I'm not afraid to drop it, I don't get distracted by social apps and notifications all the time, and it just works.

I must admit I've never had this problem, but I do leave my phone to charge most of the time.

You can, however, pick up a phone with long battery life if you want. The Nokia 106 for example – specced for over a month on standby, 10 hours talking.
