As Apple launches the official version of iOS 26.5, the question that many iPhone users are most concerned about is still “Will this version consume more power?” Especially for the previous versions such as iOS 26.4, iOS 26.4.1 and iOS 26.4.2, users have successively reported problems with heating, power loss in standby and battery life decline, which has also made many people hold a wait-and-see attitude towards iOS 26.5. This article will compile the latest iOS 26.5 battery life test report to let you know the upgrade status of new and old iPhone models. If you want to know the battery life performance of iOS 26.5, you can get a comprehensive understanding of it through this statistical data.
Comparison table of iOS 26.5 battery life test data
According to the latest iOS 26.5 battery life test, the battery life performance of the older six models of iPhone 11, iPhone 12, iPhone 13, iPhone 15, iPhone 16 and iPhone SE 2 is as follows:
| iPhone models | iOS 26.5 battery life | iOS 26.4.2 battery life |
|---|---|---|
| iPhone 11 | 4 hours and 46 minutes (3 minutes less) |
4 hours and 49 minutes |
| iPhone 12 | 5 hours and 46 minutes (2 minutes less) |
5 hours and 48 minutes |
| iPhone 13 | 7 hours and 4 minutes (42 more minutes) |
6 hours and 22 minutes |
| iPhone 15 | 7 hours and 57 minutes (68 minutes less) |
9 hours and 5 minutes |
| iPhone 16 | 14 hours and 48 minutes (50 minutes more) |
13 hours and 58 minutes |
| iPhone SE 2nd generation | 3 hours and 40 minutes (1 minute less) |
3 hours and 41 minutes |
The data in this table is the test results conducted by foreign YouTuber iAppleBytes on upgrading several old iPhone models to iOS 26.5.
Judging from this iOS 26.5 battery life comparison, Apple has obviously begun to optimize system battery life more actively for iPhones. The iPhone 16 performed the best, with a battery life of 50 minutes longer than the previous version, while the iPhone 13 also unexpectedly increased by 42 minutes, which means that iOS 26.5 has significantly improved some models in terms of background power consumption, temperature control and task scheduling.
On the other hand, iPhone 11, iPhone 12 and iPhone SE 2 have hardly changed much after upgrading to iOS 26.5, which means that the old models have gradually entered the stage of maintaining the status quo.
However, it is worth noting that the iPhone 15’s battery life in iOS 26.5 is actually 68 minutes shorter than in iOS 26.4.2, making it the only model that has significantly regressed this time. It is speculated that it may be related to Apple Intelligence background processing, Liquid Glass dynamic effects and high update rate power consumption adjustments.
Compilation of iOS 26.5 battery consumption and battery life iPhone user feedback and actual experience
In addition to the above-mentioned iPhone models measured overseas, if you want to know the battery life performance of iPhone 14, iPhone 17 series or other models after upgrading to iOS 26.5, you can use the statistics of iOS 26.5 battery life data reported by users to see the overall feelings and experiences of ordinary iPhone users after the upgrade. I believe the data will be more accurate than simply asking a certain netizen:
Overall upgrade to iOS 26.5 battery life performance
In addition to actual battery life data for each iPhone, how is the performance of all users after upgrading to iOS 26.5? The differences in this part of the data can be seen from the statistical results below:
- 48.6% of users believe there will be no significant changes after upgrading to iOS 26.5
- 24.6% of users reported increased power consumption
- 26.8% of users reported that they felt power saving
Judging from the overall statistics of the latest iOS 26.5 battery life, it is believed that the iPhone upgrade consumes only 24.6% of the power. Relatively speaking, most people think that the upgrade is unnecessary, which also means that the power consumption is still the minority of 20% users.
How does iOS 26.5 battery life perform in the iOS 26 series?
Finally, according to the battery life statistics of the entire iOS 26 series, it can be found that many iPhone models have been upgraded to iOS 26.5, among which iPhone SE 2 and iPhone 13 have become the best battery life representatives of the iOS 26 series.
On the contrary, the iPhone 15 is apparently experiencing unexplained abnormal power consumption on iOS 26.5? It is not certain whether the error was caused during testing. The performance of other iPhone models in iOS 26.5 is also within a reasonable range, and there is no abnormal and obvious power consumption.
So is iOS 26.5 worth updating?
If you are currently using the iPhone 13 or iPhone 16 series, iOS 26.5 is actually a relatively stable update in recent versions. Judging from current battery life measurements, user reports and actual experience, this version has improved temperature control, standby power consumption and system fluency. In particular, many iPhone 16 Pro users mentioned that after the update, the phone is obviously less hot and background power consumption is reduced.
For the iPhone 15 series, iOS 26.5 has 68 minutes less battery life than iOS 26.4.2 this time, which means that Apple’s optimization of this generation of models may not be completely stable. If you care about battery life, often take photos and videos, or use 5G for a long time, it is recommended to observe iOS 26.5.1 or subsequent updates before deciding whether to upgrade. As for other models, you can safely upgrade to iOS 26.5 without much problem.
