iPhone 6 battery app

Apr 17, 2017
Hi everyone,

I bought an iPhone 6 used and the seller swore the battery health was great. Of course, being the trusting schmuck that I am, I believed them. With light use, this phone won't last more than an hour without shutting down. I'd go get the battery replaced at Apple, but the screen has a small crack in a corner and will need to be replaced as well, I'm sure. So minimum $150 job, even if I take it apart myself.

I decided to buy a battery case (Anker Slim Battery Case). Absolutely phenomenal buy at $55. It has a stronger battery than the original iPhone 6 (2800+ mAh vs. 1850 mAh). The only problem is, once the iphone is charged to 100%, the case shuts off and the phone drains really quickly. If I'm not paying attention, I'll lose anything I'm working on or any call I'm in the middle of.

I realized that I could likely circumvent this problem, by ensuring the phone never reaches 100% charge. It could sit at 96% for all I care, as long as it forces the battery case to keep feeding the phone with power. I've been trying to find an app that can do this or a way to configure the phone to allow this.

Anyone have any thoughts?

I've never heard of an app that does that. I doubt Apple would allow that in the App Store. One thing you can do to extend your usage time is use the phone while it's plugged in. When it's plugged in, it isn't using the phone's battery. It's something you could do at home.

Apple replaced my iPhone 6 battery at no cost two weeks ago. I was having the same problems as you - even with a battery case, battery life was really bad. Apparently lots of iPhone 6, 6s and 6 plus and 6s plus phones had problem batteries. Take it in to an Apple Store and ask. It's worth a try.

that's a good method! i will buy a one too
Honestly, after having this case for about 6 months, I would caution against it. Don't get me wrong, I absolutely love the convenience of the Anker battery case. As far as charging is concerned, it has never let me down. But here's the problem...

When the case charges my iPhone battery, the iPhone battery generates heat. This is perfectly normal and happens to all batteries. But the case insulates the phone, trapping the heat inside. It gets really hot in there. So much so that I've now lost two batteries because of it. Thankfully, I've gotten good at changing iPhone 6 batteries.

I've taken the battery case off my phone and my phone doesn't overheat any more when charging. I seriously miss the Anker case and wish it didn't create this problem, but I'm not willing to have something vital get fried in my phone in order to not have to plug my phone into the wall when the power gets low.

Just something to think about before you rush off and get a battery case of any kind.
