The life of a battery is not based on the number of times you charge it but on the total amount of current you use out of the battery. Any time you have a charger plugged in the battery's life is not being shortened because nearly all of the power used is provided by the charger and not by the battery. The only reason for frequently charging a battery is in case you may run it down before you are able to recharge it again. Batteries, and the equipment they are used in, have been developed to the point they pretty much protect themselves from over charging and over heating. They will quit working rather than become damaged. While other types of batteries could become hot enough to blister your sking or leak some unpleasant chemical, lithium batteries can fail by catching on fire. That is why so much effort and money has been invested in battery safety. Considering how many billions have been made, and how much users demand they be more powerful, the number of serious battery failures is continuing to decrease.

As for things you can do to make the battery go longer between charges, you can turn off the display (or actually I mean turn down the brightness of the display). Turn off automatic brightness, the manually set the display to a very low brightness level. This means you will manually have to turn it back up if you want to show a sighted person something. Using the Voice Over curtain feature is not the same, and does not save any battery. As for the phone getting warm, I think this is just lack of cooling air circulating around it; especially as you describe it slipping down in the chair, but the bed is also a good insulator, even on one side. If it's plugged in when you feel it getting warm, I'd say this is normal. Sometimes my phone gets warm even when not plugged in, but that's when I'm using it a lot by talking or otherwise causing it to transmit (typing in texts, emails, other transmissions). I would think you could still by a battery case for your phone, certainly you can just buy an external battery to plug it into for charging.

I am hoping someone can give me some thoughts, or advice. First of all, my phone is up to date. I have the 5S. I can upgrade by February, but I don't know if I will. I am paying for this phone monthly. Anyway, I have been noticing that sometimes my batter runs down faster. I am on my phone quite a lot some days, more than other days. Not always making calls, but checking out Facebook, and maybe commenting on posts, or making posts. Checking my email, or maybe writing some emails. Playing Farkle. Maybe reading a news story, and definitely texting! That's certainly the biggest thing. I do this all over WIFI. Every once in a while, I may play a video of some sort. But I use my Ipad for most of this. I don't know what causes more battery useage than other things. I am getting better at closing Apps if I am not using them. My biggest problem, is that I don't let my phone die, or completely run down, before charging it. I have heard this can be a bad thing. I will usually let it get to 40 percent, and then charge it. Sometimes 20 percent, if I am still wanting to finish up something quickly. So, are there things I could possibly change, to help save battery life? How low should my battery life really get, before charging my phone? I do not care for the low power mode. So I choose not to use it. Also, are there affordable battery packs, or anything like that, still available for the 5S? Now to my next question, and something that is concerning me more. About 3 times so far, in the last week, I have found that my phone gets pretty warm. I don't know why this is happening, or what could be causing it. Once it happened when my phone was laying on my bed. I don't always keep it on my bed. Just sometimes. Another time it happened when I was sitting in my rocker-recliner. The phone always ends up sliding down, between the arm of the chair, and the seat. It's never been an issue before. It has also happened while sitting on my desk. I do not keep it near my laptop. I am very caucious regarding this. Is this possibly a bad sign? Should I be concerned? What can I do about it, if anything. The phone does have a plastic cover over it, but it only covers the back of the phone. My phone doesn't get dropped, or anything like that. Any thoughts, or suggestions would be very much appreciated. Thank you, Terri -- The following information is important for all members of the V iPhone list.
