'I tested with Geekbench and got 1466 Single and 2512 Multi results (measuring the processing speed of one and many calculations). Whether or not I turn on battery saving mode, the result is the same. After replacing the battery, I checked it again, the result was 2526 Single and 4456 Multi. Since then it is clear that Apple has slowed the phone when the battery is old, 'the article said.

Results of testing iPhone 6S with Geekbench

Just a year ago, Apple launched a repair program for the iPhone 6S after users complained of their phone crashing unexpectedly. Apple said the reason was due to the manufacturer and only affected a small number of users, then replaced the battery for free with devices with very limited serials.

A few months later, Apple said there were more devices with errors than they thought and released a 10.2.1 update, saying that the shutdown unexpectedly dropped 80% on iPhone 6S and 70% on iPhone 6 devices in general.

At that time, many people guessed that the update was actually Apple only changing the battery management system on iOS. IPhone users have long complained about slow machines, especially after updating or using them for a long time. Changing batteries can help iPhone 6 phones run faster than not new, but the Apple deliberately slowing down the machine caused great controversy. The above post made the doubts around this action clearer.

While Apple says the battery saver mode Low Power Mode can slow down the device, it is not. The same thing happens on MacBook when the device runs significantly more sensitive after changing the battery. As for why the iPhone 7 is not affected later, the reason is that the A10 and A11 chips have a different battery structure, containing certain cores to handle high-demand tasks.

Users can self-test iPhone speed by CpuDasherX application.

If you are using an iPhone 6 or iPhone 6S that is slow, you can replace the battery to help solve the problem. Note that purchase genuine batteries at Apple authorized dealers.https://locate.apple.com/vn/en/sales/?pt=1&lat=10.75&lon=106.6666667
