Performance of an iPhone 7 with iOS 15, is the battery good?

This week iOS 15 officially arrived and with it the classic doubts of always about how is its performance were generated, especially in older devices. The iPhone 7 and 7 Plus are among the oldest that support this version (the ‘6s’ are the ones that mark the cut-off line) and therefore we find it interesting to tell you what experience we have had. Fluidity , battery , bugs … We will tell you below everything we have been able to analyze.

Performance of an iPhone 7 with iOS 15

Precedents: in which model have we tested it?

Although in the ITIGIC writing we already carry more recent devices, we continue to save some iPhone from past generations and we used them last Monday when iOS 15 came out. Device that, in addition, we restored the factory to be able to carry out a more complete test at the level of performance.

It is an iPhone 7 with a capacity of 128 GB bought in November 2016 and with a battery health of 89% . It should be noted that this component was replaced a year and a half ago, so under normal conditions of prolonged use and without having changed the battery, surely its health would be much lower.

This has been its performance with iOS 15

After updating the device and having tested it for several days we have been able to realize several things. The first thing is that at the level of autonomy you do not notice too much difference with iOS 14. Even in its best moment it was not an iPhone that shone with its battery, so we could not expect miracles considering its wear and tear. This is the use we made of it:

  • Apple TV + / Netflix / Disney + / YouTube: 41%
  • Twitter: 28%
  • Safari: 12%
  • Telegram: 9%
  • Instagram: 6%
  • Camera: 2%
  • WhatsApp: 2%

This has been the average of use that we have made from 7:00 in the morning and even at night. On its best day of performance, it arrived with 3 % at 7:00 p.m., while in the rest of the days the iPhone was already without battery at around 3:00 p.m. to 3:30 p.m. That is, around 8 hours since it is disconnected from the charger, but with the screen on about 3-4 hours. Nothing remarkable really, but we insist that with iOS 14 it was similar.

At the level of fluidity of the system we must say that we have found that it is going quite well and the A10 Fusion chip is still capable of moving everything efficiently. Some apps take longer to load content than on the new iPhones, of course, but nothing to worry about. Yes, we have found some bugs such as that Instagram stories are not heard or that from time to time an app closes unexpectedly after opening it, but in the end they are problems detected in other more recent devices , so it is not directly attributable to the iPhone 7.

Therefore, at a general level we can say that it has been a good experience and that we recommend updating to everyone who has this device. Now, to avoid overloading the system with information, it is advisable to restore the system from scratch. In addition, as far as possible, it would also be advisable to change the battery if you are going to stay with the terminal for at least one more year, as this will give it a completely new life and will alleviate its main problem today.
