Hey fellas,

When battery is maintained between 20 and 80 percentage, it functions the best. So I am looking for a tweak, which when enabled should keep the battery between 20 and 80.

I have tried searching but couldn't find any. There are many that would disable wifi and all when battery hits 20 or anything you want.

Interesting, I've never heard about this 20 and 80 percent thing. I would be interested in a tweak that can shut off certain things based on battery life.

Yes, the battery stays the best when it's kept between 20 and 80. Try googling. You will find a lot of links.

Btw what you are looking is a tweak named batterysafe. It should help you. :)

Here are a few links that promotes the fact of keeping the battery healthy.

Since we all are on the same page, Is there any tweak as I am looking for?
Not that I am aware of but here's the deal, if you have an ipod touch or an iphone, it's really good if you can charge it between 21 and 79 and if you have an ipad, charge it between 11 and 79.

Since its not possible to manually keep a track of it, I am looking for a tweak that would be able to.

Otherwise, I try and keep it between 20 and 80 all the time. But it has its own limitations when you are charging overnight and so on.

I'm not sure this even makes sense, no tweak will stop your battery from draining, why can't you manually keep track, just plug it in between the two numbers you stated?

Why not charge it upto 80% and let it run down to 20% then charge it?
I have an obsession about batteries and I did some research and I found out this and many experts approved this, in fact there is an association that says this.

Actually what I am looking is battery stops getting charged beyond 80. A tweak that tells the os to cut off power when it hits 80. It's like 80 is the new 100. That way. Of course u can't stop draining a battery. So it's like just stopping at 80 and about charging it beyond 20 is our job.

----------

Why not charge it upto 80% and let it run down to 20% then charge it?
That's how I do it now. However when I plug it in over night or forgot to take it off when it hits 80. Not that it's doing any thing and to the battery. However an automatic cut off would be ideal.

For me it's more of maintenance. I can prolong my battery's life with this.

wow you think way too much about it, just enjoy your device and replace it after the 2 years cycle with the next gen ;) even the battery on my 3rd gen iPad and old iPhone 4S appear to be just fine and i charge my iPhone whenever and sometimes twice a day

No such thing exists because it isn't needed. By the time the battery even starts to show age related problems, the device will have been outdated by at least four years. In summation, don't worry about it and use the device as it.

Damn maybe I should have been following the 20-80% rule all along. My iphone 5 is only 11 months old and already showing tons of battery degradation.

I guess it just gives me a good excuse to get a 5s before 7.1 comes out in march.

In 3 and a half years, my iphone 4 lost only 250 mAh.

Wait, Apple states on their website that their batteries should have at least 80% of their capacity left after 1000 cycles. Since your approach would never actually make use of the full 100% anyway, you can just as as well use it like everybody else. If you ever hit 1000 circles on your device, the problem won't exist any longer, because your battery's capacity will be down to 80% anyway. Problem solved.

Those statistics are for Apple's laptops. Their iDevices are rated for 300-400 cycles depending on the model.

Ok then, 300 cycles. But, IMO, it still doesn't make much sense not to use the full 100%. Don't Liion batteries by design rather quickly drop to about 80% and after that the capacity decreases slower?

i'm on my 270th cycle after not even half a year according to this batterylife app and it still shows health to be 93%. not too bad
