Guys should I go repair my phone because my battery health has been acting weird lately in the past month , there were at random time where my battery health would go down a percent under 24 HOURS?! I was like what from 99 to 98 to 97 real quick , now it’s happening again from 96 to 95 . If i don’t need to repair then what should i do? Please give me an answer ( Oh and my phone keep getting heated so fast while charging lately )
Your percentage is in whole numbers, and is truncated, not rounded. So if it goes from 96.0% to 95.9% that would be displayed as a drop from 96% to 95%. And as batteries are analog and chemical, the loss of capacity will not always be linear. The only meaningful measure is over longer time spans. As you can see below, on average an iPhone will lose about 1% per month. So if the final number is 95% and the phone is 5 months old that would be about right. If the phone is more than 5 months old you are ahead of the curve.
More detail: 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”. 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.
Once the capacity drops below 80%, or if there is a message in Battery Health that the battery is not meeting peak performance expectations, it’s time to change the battery→iPhone Battery Replacement - Official Apple Support
The absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity 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.

To conserve battery life, go to Settings - Battery - Low Power Mode
The battery drains at different rates based on usage and background processes. I personally charge my iPhone every night and have optimized battery charging enabled. This should give you the longest battery life possible.
I have the optimised battery turned on but not low power mode of course , but it was just so weird to drain that fast within a day 😭and I noticed that my phone was always heated so fast after charging unlike before
Thank youu so muchh for all the details😭😭😭 I didn’t know this is how it works and taht i thought charging overnight was bad but it’s actually the opposite! 😌 and yes you are right about if my phone was about 5 months old then it must’ve been around at 95% I bought this on 17th November 2022
Hey Everyone,
I bought Iphone 14 pro in 1st month 2023. When I use mostly in a day. I see my mobile is heated. I am confused what I can do for the heated problem?
I paned to sell it & buy a brand new android phone.
Even I’m facing same issue I purchased on may 19th 2023 and now my battery life is 95 % spending huge amount on this is totally waste. After this issue I have decided not to buy any iPhone
Battery health of Iphone 14 pro max
