Is charging the battery constantly bad?

Tip us?

The worst thing you can do to lithium-ion batteries is let them discharge completely.

Not letting the lithium-ion batteries discharge more than 10% will increase the cycles by thousands we're talking going from 350 cycles to 4000.
So, ideally, you want to charge your batteries (of this type) after a 10% discharge but we all know that's impossible so the best thing you can do is to charge your tablet everytime you can. Even if it has much battery left.

You should charge to 100%, there is no problem with that.
On a perfect world you would want to charge everytime the battery hit 90%, this gives the best amount of charge cycles and life time.
However we all know that's not going to happen because the tablet is here to serve our needs and not the other way around so stick to charging it whenever you can.

Default Great Question!

First let me start off by saying to the person that started this thread that this was a really good question to ask!

Now if you are trying to get the most out of your battery then you could look into installing/flashing a custom kernel that could allow for undervolting which could in theory give your battery more life.

So you all are saying that the best thing to do is to charge up to 90% and never let it get down to less than 10%? Always start charging when the battery gets to like 40%?


One question i have for the Nexus 7 2013. Is it even possible to remove the battery for this tablet or does it void the warranty? Second has anyone purchased a spare battery (if possible) for their Nexus 7 2013? If you did could you post a link to where you got it and let us know how much you paid?...

Great question and thread!

There has been speculation in the franco thread that undervolting could actually hurt battery charge life, due to the CPU having to work harder due to having less voltage, not sure if that has any merit or not.

The reasoning behind the not charging above 90%, and not allowing full-cycle charges is outlined much better in the links I posted than I could do here, also I would be just regurgitating information that is already there for the most part.

40% is just a number I pulled out of air, the best practice is to keep the charge delta as small as possible. So, let's say we charge the device to 90%, it is better to charge it when it hits 80% than it is to wait till it hits 70%, because a smaller charge delta has occurred, so charge often, but if you want the lifetime of your battery to be maximized (lifetime as in the way ezas explained it, i.e. "(...)battery longevity. How long until the battery begins to lose the ability to fully charge"), than try to not charge it to 100%.

Also, it has to be said, heat also affects the battery longevity, that is why I also recommend not charging while a device is in its case. And not leaving it sit on a Qi charger for too long, some cause more heat than others, but heat is a battery's enemy.

It would no doubt void your warranty. As for battery replacements, I have not yet found one, I'm not saying there isn't one to be found, but I have yet to find it, I figure the reason is because they are not yet in demand since the tablet is relatively new and demands for replacement batteries would be too low, obviously and eventually this will change.
Kenneth, what is the frequency? Teach a man to set a fire, and he will stay warm for a night. Set a man on fire, and he will stay warm for the rest of his life.

What I said was that, theorically, in a perfect world, you want to charge your tablet when it starts losing charge and ideally never let it get below 90%. This is almost impossible because we use our tablet and we don't want to constantly be charging it so ideally you want to charge it whenever you can.
