iPhone Keeps Randomly Crashing, Rebooting, and Showing Extreme Battery Drain

I wish you would get through your head that is irrelevant. You phone needs a battery. The reason it does is also irrelevant. Although it was probably on the verge of failure and failed coincidentally, or perhaps it was weakening and you didn’t notice.

Battery capacity isn’t necessarily relevant. If the battery was installed improperly or the wrong type of battery was involved, that could trigger the “service” indicator also.

I know it’s difficult with stores being closed to get serviced.

Have you tried updating the phone again? You mentioned iOS 14.0.1 earlier which has since been replaced by 14.1. According to Apple the latter contains numerous bug fixes and improvements which could help.

missterius,

Definitely let me know how it goes. I will await the results.

Try to remember that the iPhone is NOT a phone but a portable and extremely powerful hand held S.M.A.R.T. computer. It is an extremely complicated device that does everything we need it to, we want it to, and we never thought about it ever doing. We could be dragging around a laptop, a phone, game console, books, boom box, cd’s, calendars, etc... OR an iPhone. Yes, I had a difficult time adapting to the iPhone, my first Apple product ever, because it had little annoying bugs I felt offended that Apple expected me to put up with. But I ended up absolutely addicted to every one of my iPhones and don’t know what I would do with out it. I absolutely trust and respect Apple and it’s devices. It is everything I need in one tiny little amazing hand held device. And in my opinion, Apple’s iPhones are un-rivaled. So yes, you have the right to be frustrated but remember what it actually does for us and as I had to do... we have to stop expecting perfection from a fluid , constantly growing, always increasing in amazing functions, and abilities in an extremely powerful device. Let’s give Apple the appreciation and break it truly deserves. Plus you have to respect a company that created a forum where it’s users can vent about IT and still provide the help to the frustrated, from a large community to address issues you are having with THE company’s product. Hang in there... powerful technology deserves our participation in making it better. We are here to help you do just that. But yes, you have every right to be upset, angry, irritated, frustrated... but not for too long because you need help in figuring out your phones particular personality quirks. We were here to help. 😎 Hang in there!

Apple’s software Quality Assurance has definitely gone downhill recently. Even though I’ve had no battery issues, iOS 13 and 14 have both been riddled with bugs from the start.

This is why I generally wait till minor updates are released before moving up to a new software version just to escape the worst of it. Things should improve with time.

mistterius,

I absolutely agree with you. I completely understand your frustration. As I have posted in response to someone else, I come from the hard drive microcontroller firmware development arena. Our product functionality requirements are extremely high and testing is an intensely vast process and no firmware goes out with out a 100% score on every test. Yes, customers would instantaneously flee if our devices did not securely protect their data integrity. Apple iPhones are a very different animal that it took me years to adapt to its reality. Apple, in my opinion, is always producing so many different feature that are truly meaningful, always giving us more operations, abilities at a scale and rate that is actually hard to keep up with. The by product of which are bugs and that is the Apple realm of reality. But I absolutely understand your position and frustration.

Even if you are tired of hearing it, your battery is bad. Those are the symptoms of a failing battery with high internal resistance. And I have read the whole thread, several times over, and that doesn’t change the fact that your battery is bad. You can use the Contact Support link at the top of this page, where a technician can run a remote diagnostic, and then she can tell you that your battery is bad rather than other users telling you that your battery is bad, but that doesn’t change the fact that your battery is bad.

Mistterius,

I am NO expert just an iPhone 11, iOS 14.1 user. My phone has the intermittent issue where I will have my phone charging all night just to show only 10% charged when it had a a higher charge before I connected it to charge. It happened when I woke up yesterday morning.

I have not experienced the serious consequences you have because I have the Apple iPhone 11 SMART battery case on my iPhone. When my battery is at 10% charged in the mornings after charging all night, it has drained the entire SMART battery(which I’ve never been able to drain by just use) and the iPhones battery except for the 10%.

When this happens, I have to remove the battery pack from the phone and charge them independently but the iPhone still shows problems trying to charge. Yesterday I went through all the steps turn off background app refresh, close all .... . I kept watching the battery charging in the upper right corner of the screen and it was flickering between white and barely viable green. I could explain why I did what I did next but who cares, anyhow I turned cellular off(don’t ask why) then just kept pulling power from the phone and plugging it back in. I watched the battery in the corner and after the 4th time the battery in the corner showed green and charging. It charged quickly and is fine again till it happens again.

Now, I am NOT saying that ‘Cellular’ being turned off had ANYTHING AT ALL to do with alleviating the battery issue NOR am I saying that ‘Cellular’ being ON caused or contributed to the issue. SO please DONT feel there need to school me on how utterly ridiculous and ignorant I am because I am NOT even insinuating that ‘Cellular’ being OFF or ON at the time, played any role what so ever in the causation of or the resolution of my battery NOT charging. Just stating the steps, trial and error, I took.

Hi mistterius,

I do NOT agree with those who jump to the problem being a bad battery. Some few cases could very well be due to battery issues BUT the vast majority of these extreme battery drainage issues are NOT due to bad battery. I believe this is a HARDWARE issue but it could just as well be a software issue-possibly tied to the power commands/states. I am confident that a far greater number of people KNOW this is a real issue that replacing the battery will NOT fix.

Hi mistterius,

I don’t know much but I did know a new battery would do nothing at all to fix the problems you are having. Yes, this community is made up of regular users who have knowledge to share, advice to give, opinions to present, passion behind their theories regarding issues, etc... but mainly we are here to help and get help with iPhones. You have 100000 people, you could receive 100000 different opinions. It’s frustrating to have so many different points of views and opinions regarding one issue and that is what we do here. We present you with a number of viable options to pursue towards fixing your issue AND you get to root through them all till you decide which one you will attempt first. There are NO guarantees or warranties on this site, that with our help, your issues will be resolved. All we agree to do is TRY to help the best that we can. So, now it’s a fact that your battery WAS not the problem, you know that because many took the time to present their opinions and replacing the battery won as the next thing to do. So, what will you try now?
