Check out this video that compares the performance of the iPhone 6s before and after swapping the battery.

Performance comparison for before/after battery replacement on iPhone 6S. Same phone, different battery.

In December, Apple announced it would be dropping the price of battery replacements from $79 to $29 after it was discovered that iPhones were being secretly slowed down as their batteries aged. Apple touts the slowdown as a feature but it was put in place to avoid unexpected shutdowns on the iPhone 6s; something that doesn't appear to have commonly occurred with earlier generation devices. Rival smartphone manufacturers have since announced that they do not throttle their devices casting doubt on Apple's claim that this is necessary due to the nature of lithium-ion batteries. Already seeded to developers, the upcoming iOS 11.3 software update will show battery health, recommend if a battery needs to be serviced, and allow users to disable throttling. Unfortunately, turning off throttling will not solve the unexpected shutdown problem for users with an iPhone 6/6s.

Currently, there are over 60 class action lawsuits and various investigations opened into the iPhone slowdown. As you can see in the video, there's a notable speed improvement after changing your battery.

Below are links to replacement batteries for each iPhone below for those who want the performance boost of a new battery but can't have Apple perform the replacement for whatever reason (timing, jailbreak, location, etc).

You can get Apple to test your battery over WiFi. That way you will have some idea of the status before looking to replace. I did that and did not need to replace the battery

For all to know: All aftermarket batteries aren't OEM (even iFixit while theirs is a good one), the only way to get a legit battery is either via an AASP, or an Apple Store. Risks using non-OEM batteries are real: explosions, catching fire or destroying the power management chip. If you're jailbroken, make your case very clear to them and do some research, your mileage may vary. As a suggestion: have a backup on iTunes done first, then run Cydia Eraser, that wipes everything and keeps your current iOS - once done, reinstall the Apple TV beta profile to stop the OTA daemon. If you didn't play with system files, Eraser takes no further than 5 minutes to complete :)

I installed a new battery in my iPhone 6 and it did show improvement right after and battery life did improve, but then within a few days performance degraded and the phone struggles to keep up with regular typing in most applications. It doesn’t randomly shut off hardly at all, but often does randomly crash the springboard when doing the most simple of functions in different apps. Maybe the software switch in 11.2 is broken and didn’t actually shut off my performance throttling? Idk but I guess all I can do is deal with it:/

go to dfu mode abd restore your iphone to clean one, that helped me to clear my phone

Does anyone know if this throttling even affected iPhone 5? I have an iPhone 5 and was wondering should I buy a new iPhone vs. upgrade the battery to see the performance?

It’s the software updates that made the throttling more pronounced. If you didn’t update past iOS 10, you may be fine.

Well my accidentally updated to latest iOS 11. Is there a way to downgrade it to 10?

Also FYI my iPhone is not jail broken.

Most likely not since Apple stopped serving for iOS 10

The given links for battery purchase are for genuine or OEM batteries or duplicate or 1st copy?
