Today’s mobile phones have many battery care modes, including a mode that limits charging to 80%, which many people want to know how it will be after 1 year. Recently, the MacRumors website has revealed the results of the test from September 2023 until now. The results are as follows:
Results from the test with 80% charging capacity
- Battery capacity: 94%
- Number of charging cycles: 299 rounds
In early 2024, my battery capacity was still above 97%, but it started to drop rapidly over the last 2-3 months.
Note:
It must be admitted that doing this has some days when the battery runs out quickly because the amount of power may not be enough at times, so we have to carry a spare battery, which is not very convenient.
Factors affecting the experiment:
- Mostly charged via USB-C, and some via MagSafe, at a ratio of about 70/30.
- Often let the battery run out of power before charging and do not leave it plugged in for long periods of time.
- Charge in a room with a temperature of approximately 22 degrees Celsius.
Compare that to the MacRumors team’s iPhone 15 Pro Max, which has no charging limit:
- Battery capacity: 87% Number of charging cycles: 329 cycles
- Battery capacity: 90% Number of charging cycles: 271 cycles
From the data, it seems that limiting the charge to 80% preserves the battery capacity better, but it doesn’t make a huge difference. I have more than 4% battery and less than 28 charge cycles, so I’m not sure if limiting the charge to 80% for 12 months is worth it.
But after the results of this experiment come out, the results may not be seen today, but we have to wait and see in the next 2-3 years. I will continue to use this feature. Do you think this feature is worth it? Let’s think about it.
