I bought iPhone 11 pro max 2 months and my battery health has dropped down from 100% to 97% within a week of time. Kindly help me to solve this issue.
I am hoping to hear from the community the soonest.
Thank you,
I have invested hugely in this and seeing battery health fall drastically within no time is heartbreaking.
iPhone 11 Pro Max, iOS 14
Hello rounak_raj_surana,
We understand that you have some concerns regarding your battery health.
The battery health can be affected by a few different factors, such as charge cycles, and how it was cared for. For example, charging it in an area that has a high ambient temperature can be detrimental to its longevity.
These tips will help you to maximize your daily battery performance and its overall life.
Also, since you have an iPhone 11 Pro Max, a recalibration of the battery was released in iOS 14.5 and later which helps to give it a more accurate reading. This could be why you now see a difference. This guide has more info.
Having said that, your battery health is still well within the acceptable range, and should not be replaced until it's at 80% or lower or if you see a specific battery alert.
Are you having any issues with battery life, or is the only concern the battery health?
Take care, and we hope to hear back from you soon.

Batteries are consumables; they lose a little capacity every time they are discharged, then recharged. On average this works out to about a 1% loss for every 25 “full charge cycles” ( some will be a little more, others a little less). As one example, if you charge the phone overnight, every night (and that is what you should do; it is a best practice), it starts the day at 100%. If it drops to 20% by the end of the day before you charge it again overnight that counts as 0.8 full charge cycles (20% to 100%), or about 24 full charge cycles per month of use. For this example your battery capacity will lose about 1% per month. Of course, if the end-of-day level is higher than 20% the capacity loss will be a little less, and if it is lower than 20%, or you charge it during the day, the capacity loss will be higher.
The absolute best way to improve the life of your battery long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.
I have been charging my phone at room temperature of around 25C.
inam sure that cannot be a problem.
Talking about the usage i am a bare minimal user, the reason i shifted to IOS was the standards, trust which they have build but seems to be it is flying off within no time.
If we talk about calibration too within 2months of time my battery health falling down 3% straight is a drawback.
Battery life being a 4000mah battery i am sure it shouldn’t fall this early, and to be that it is drastically falling down too.
Hope to hear from you soon.
Thanks for getting back to us rounak_raj_surana,
Are we to understand that other than the drop in battery health, there are no other battery issues with the device?
If that is the case, then the drop would not be considered abnormal, and really does depend on several factors, of which charging behavior and usage are included.
If you still have concerns over the health, we suggest contacting Apple Support to see what type of troubleshooting options they have available: Get Support
Take care.
Sudden drop in battery health
