How to improve battery maximum capacity or how the settings of the phone should be to keep the battery capacity stable.

My battery maximum capacity is deproving day by day...few days back it was 95% and now it is 89%

Basically communities are made so that one can share their experience with others and collectively the community evolves to become better and enhance its knowledge level. Good Samaritans of the society will never have malicious intentions to mislead others. 


Let me clarify further.


Technical Specifications are made after carrying out extensive trials and test under certain boundary conditions. These boundary conditions may not be same for all users. Thus experience of one varies from another. 


The country where I belong, we only have 84 % of population covered with Cellular Network and <1%,  repeat <1%, with wifi connectivity. Connecting to a wifi is a luxury here.


We can simulate 3 (three) test conditions at your home which will eventually tell you that I am not here to mislead others but to share my experience.


The three tests are as follows (Irrespective of the Phone brand, battery conditions, model, age, OS in your phone). 


  1. iPhone connected to a known wifi

Connect your iPhone to a known wifi and note the battery drainage time using a stop watch, say from 100% to 70%

Larger the battery drain spread the better, for accurate results


  • iPhone trying to connect to unknown wifi

Connect your iPhone to a known wifi and note the battery drainage time using a stop watch, say from 100% to 70%

Larger the battery drain spread the better, for accurate results


  • iPhone looking for wifi signals (No wifi)

Leave your iPhone with wifi ON condition and note the battery drainage time using a stop watch, say from 100% to 70%

Larger the battery drain spread the better, for accurate results


You may do the same tests with other brands too and you will encounter similar experience. 


Good Luck!

Day by day or hour by hour battery health readouts are pointless and meaningless. Estimated battery health fluctuates with the load on the device processor, power use by the radios, the local temperature and humidity, number of charge cycles, etc, etc. It’s an approximate estimate only, and it’s changing constantly.


If you must obsessively monitor your battery health, pick a specific day and time of day, and check it once a month on that day and time. That monthly trend will be more informative of how your battery is aging that any short term interval check ever will be.


Tracking the health readout frequently is like trying to mentally guess your car’s miles per gallon by staring fixedly at the fuel level needle and trying to estimate how fast it’s changing relative to the starting amount of gas in the tank.

You shouldn’t let your battery lower than 20%. Every lithium-ion battery comes with a fixed amount of charge cycles (the number of times you can charge up to 100 percent and run down to 0 percent). An iPhone has a lifespan of about 400 to 500 charge cycles. But that doesn’t mean you can only plug it in 500 times—it means you have 500 chances to let it go from a full charge to no charge at all. So, if you let your battery drain completely every day, it will last 500 days. If you charge it before it drains and top it off throughout the day, you’ll stretch out the time those 500 charges will last.

There is one reason to let your battery drain completely. If it “dies” when the battery icon is showing a positive charge, it means the battery needs to be recalibrated. Draining it all the way down then charging it up again should fix the issue.

Yes Yes Yes Yes


Technically when in roaming it will keep searching for wifi and Bluetooth signal till it finds one.

After connection it will be stable

Again when you go out of range it will start looking for signals / network when in roaming


The same is is true for Cellular signal but you do not have much of a choice there because you need to keep looking for network or else there is no reason for having a mobile.


Please try my tips when in ROAMING.
