iPhone SE 2020 battery health

To those commenting this is normal, it’s not. Stop. At the rate at which the battery health is decreasing, it looks like it won’t last 2 years?

FYI, as SE users we were aware our battery life would be average when we bought it. However, battery life ≠ battery health! Heck, battery life on the 1st SE model did not degrade this quick and why is this only happening to SE and not iphone 11/12 models?

New SE is a little over a month old and the battery health has already dropped to 99%. Apple support says you can’t request a replacement until it drops under 80%. My iPhone 7 dropped to 97% after a month and the only way I could make it all day was to immediately put the “low power” mode after charging. The iPhone I had prior to these were the 1st generation iPhone SE. The battery in those lasted over 2 years before they dropped off the 100% mark. Apple support says there is little difference in the few percentage points drop but my experience has been anything that’s less than 100% means your phone is not going to last a day. Why are the newer iPhone batteries so bad. Other companies batteries are improving but Apple is getting worse.

It is not just you, it is this line of iPhone. My old SE was approximately 2 years old before the health dropped from 100%. If this battery health decline is like the first SE once it drops below 100% the phone tends to die much quicker. I’ve read that it represents only 1% but my experience is much different. To make it through just the work day I had to activate the low power mode as soon as I unplugged it. I hope Apple realizes the problem and can do a software fix if possible.

ragnar148 is right!

It should not be aging so fast. My SE1 had 88% after 4 years. Today my SE2 has 91% after 10 months...?!!

My theory is: The SE2 has also old batteries from iPhone 8 and older. They were not used for a long long time and now they are aging faster.

What do You say about that, Apple?

kind regards

hey friend, I have the same problem. As I wrote before I am almost sure, the problem are batteries themselves- they are taken from the old iPhone 8 line ( like literally everything in this model instead of processor ) and were laying not being used for years. Thats why now they are aging faster...

Yep I think so too after the recent update atleast that’s what most of the forms on google thought and yes I use low battery mode had to turn of feautures like listen for hey Siri background app refresh and more

I just found this Website, https://osxdaily.com/2018/01/27/determine-iphone-new-refurbished-replaced/ , where they describe if your phone is a new or refurbished device. According to this website, my pre-ordered SE from April '20 is a refurbished device. The serial number of my SE is starting with an 'F'.

I've read rumors that Apple might just have used old iPhone 8 to 'upgrade' them to an iPhone SE.

Although I appreciate recycling/refurbishing, I am quite concerned if they might have used the old iPhone 8 batteries..

I thought he was an Apple employee also except he doesn’t offer any suggestions on how to fix the problem. I believe you because I used the older SE up till 12-24 when I got the new SE. This old SE still take the new update. Apple did have a class action suit brought against them because a update caused the battery life to deteriorate they admitted no wrong but were giving owners checks for $50. For now I will keep turning the low power mode on and keeping the screen time the lowest time of 30 seconds.

For about the first 7 months I was making sure that the battery was at 30-80%, except some overnight charges that took it to full capacity and the occasional inability to charge that took it below 20%. Well... it didn’t help whatsoever. Battery health dropped fast and now, 11 months after purchase it’s at 87%. My 6 plus is at 86% after 6 YEARS!!!

Come on! That’s not normal. Since we are so many that have the same problem it should be addressed from Apple!

it looks like this iphone have a technical problem, i have had my new iphone 7 on 2016, i returned it to Apple on Dec of 2020, because the battery health ONLY has 87%, i want to get a new iphone , so I chose iphone SE, unfortunately, i get a bad decision, after 3 1/2 month, the battery health down to 97%.

My theory is that the batteries are just OLD, chemically old. I will go soon and ask them to replace mine, even pay for that, but I want to see the production date of the new one.

It is strange situation, actually with SE1 it was similar- they could use the batteries from iPhone 5. But they were not aging as fast! Who knows, maybe there will be a big replacement program soon.

Let’s all come together and raise this issue. My iPhone’s battery health dropped to 95 in just 6 months. Latest heard a news about iPhone 11 having calibration issues.So the company agreed for free battery replacement. May be it’s the same with this model too.

While heat is not good for batteries, the iPhone is designed to always keep the battery’s temperature at a safe level.

How do I know? I have my fair share of experience with the original iPhone, iPhone 3GS, iPhone 5S, iPhone 7, iPhone 8 and iPhone XR. And my phone has heated up from time to time, especially fast charging and on long phone calls and watching videos. I have always updated to the latest version of iOS because it is the only way to keep an iPhone safe from malware. And I have never had a battery fail. And I am an electronics engineer with many years experience with battery technology.

So it isn’t heat, it is charge cycles that is the primary determinant of battery health, other than abuse such as letting the battery get so low it shuts off.

Staying on iOS 10 is a very risky thing to do, as there are quite a few security vulnerabilities in it that have been blocked in all of the later versions. Here is a list of what your phone is at risk for→Apple security updates - Apple Support

Yes, not just iPhones, but every phone is designed to always keep its battery's temperature at safe level. iPhones (old by even 2-3 generations) running latest iOS easily heats upto 36-38 degree Celsius, in extreme cases even 40-42, even with a brand new battery. Yes these temps are safe, your battery will work fine, it won't blast or catch fire, but this heat will decrease its lifespan. A battery opertaing at 30-31 degree C will always have a longer lifespan and will last for years to come. Its just basic science.

And yes the common phrase "Always keep iOS upto date to keep your phone safe from malware" But I thought iOS and MacOS are suppose to be malware free? LOL. Anyway I am a CSE engineer myself, and I can safely say that your everyday virus and malware cannot bypass iOS security even if its not updated. Its completely safe unless the FBI or CIA is trying to hack your phone. Its just a phrase that manufacturers use to make you update to the latest version.

I bet some of the people commenting here about battery health degrading too soon has phone heating problems.

A secret ? Aren't you aware that for this very same reason Android still doesn't show battery health capacity ? Its a common thing with batteries and even with CPUs and motherboards. Not every "same CPU" has similar clock speeds or voltages, there are always slight variations. And regarding 3rd party app, 3uTools show every detail of any iPhone. It shows the battery health precisely and its charge cycles.
