battery drain

Hey there Hsai99,

Being able to rely on as long lasting of a battery is important, and we'd like to help look into what's draining your battery so quickly.

Let's start with better understanding what's happening, along with ruling out some basics:

1. How long does your iPhone last from a full charge?
2. How long ago did you update to iOS 15.2? Battery life may be less than expected for a short time after updating. This occurs due to it downloading app data, syncing contacts, indexing search results, and completing the digital housekeeping for a new update.
3. Is it being used within its temperature range? Check for the range near the top here: If your iPhone, iPad, or iPod touch gets too hot or too cold
4. Any app updates? Check out: How to manually update apps on your Apple device
5. Have you already tried any battery tips? Let us know if you’ve already been trying all of these for at least 48 hours after updating to iOS 15.2: Maximizing Battery Life and Lifespan

We look forward to hearing about these details in your next message. Take care until then!

Troubleshooting iPhone Battery Draining:

I. Battery Drain Info:

The iPhone battery will drain, unless it is plugged in and charging. With lots installed, the charge would be slower. As for how fast it would drain the battery, that would depend on the Battery Health and the volume (sound) you use.

1. Go Here: iPhone Battery and Performance - Apple Support
2. Scroll Down: to "Your battery's maximum capacity"

II. Troubleshooting the Battery:

• Charge and Monitor the iPhone Battery - Apple Support

• About the Battery Usage on your iPhone - Apple Support

• About Optimized Battery Charging on your iPhone - Apple Support

• If you see "Your iPhone Battery may Need to be Serviced" - Apple Support

• Use Low Power Mode to Save Battery Life on your iPhone - Apple Suppor

I have this problem too. My battery drains very quickly. My battery health is at 91%. I do have an iPhone 6S. I don't use it a ton. Just this morning, my battery was at 95%. I logged into my banking app and the battery dropped to 10% before I could drill down into my account. I had no other apps open. It shouldn't burn that much power that quickly. It then took about 20 minutes for the charge to get back to 100% - and I wasn't using a fancy, quick charger. I've had my batter replaced a couple of times in the past several years. Something is definitely wrong.

Yeah, I have been experiencing similar issues since I updated to 15.2 about 5 days ago as well. Apple seems to have broken something with their latest update. I reached out the their support, they don't know how to handle or work around this issue. My phone became essentially unusable as the battery appears completely discharged (while it doesn't seem to be true, as it may also jump to 20-40% after you turn the phone on again) a couple hours after it was 100%, and it automatically turns off.

Time for a New iPhone?

The percentage is all just a gustation on Apple's part. Apple recommends that you get a new battery when it gets to 80%. My former iPhone (iPhone 6) had the battery replaced thrice, and every time afterwards, it would work just fine, eventually dropping to 80%. Note that the percentage can increase as well. It's because it's a guestimation. So, consider upgrading to a newer phone to avoid a draining battery.

As ETXD88 said, the battery health is 91% on their phone. On mine it's 92%. That's considered okay by Apple (confirmed by their support). I am not sure why you would mentioned 80% while it is not the case here.
