Unexpected battery life on older iPhones

iOS 18.7.3 brings more than 5.5 hours of battery life on battery-maintained iPhones and smooth performance, worthy of the best update.

Apple has just released iOS 18.7.3 as an important security patch, but experience shows that this can be one of the best and most stable updates for older devices like iPhone XS, XR or iPhone 11 Series.

Impressive battery life even when the device says “Maintenance”

The most surprising thing in this test came from the battery life. The iPhone

However, after a day of intense use, iOS 18.7.3 optimized energy excellently. With about 90% battery consumption, the device still achieved 5 hours and 37 minutes of On-screen time.

This result becomes even more valuable when looking at the tasks performed. The user watched Netflix continuously for more than 3 hours – a task that consumes a lot of screen power and network connection, combined with surfing Threads, Instagram and running many GPU performance tests.

The fact that an older device with a weak battery can survive such heavy entertainment tasks proves that Apple has fine-tuned the power management capabilities on this version 18.7.3. If your battery is still good, the usage time will certainly be much more impressive.

Smooth performance and outstanding Benchmark scores

In terms of performance, iOS 18.7.3 feels “rounded” and stable. During the first 24 hours of use, there were almost no minor errors or annoying lag phenomena.

The only small minus point is that when pulling down the Control Center bar for the first time after booting, the device may slow down a bit due to having to reload the interface, but this is completely understandable with 7-year-old hardware and does not repeat itself during subsequent use.

Benchmark tests also reinforce this statement of stability. Geekbench scores recorded on iOS 18.7.3 show superiority compared to the average of previous versions.

Both single-core and multi-core scores are high, and in particular, the GPU Metal score reached 9944 points, much higher than average. This means that the ability to handle graphics and daily tasks on this update is in the best state that the hardware can handle.

The most complete version for “aging”

To sum up, iOS 18.7.3 is more than just a dry security patch. It’s like a final gift of gratitude that Apple gives to older devices before they completely stop supporting them.

The perfect balance between long battery life and smooth performance makes this the most polished version of iOS 18 to date.

If you are using older devices and are on iOS 18.7.2 or lower, don’t hesitate to update to iOS 18.7.3 immediately. This will be the safest and most stable destination for your iPhone to continue to serve your entertainment and daily communication needs well in the near future.
