iPhone 6S slow and low benchmark scores.

OK, I bought the battery from Amazon (where else would you get it from? :-) ) so does it mean that I got a poor quality battery?

Probably but there's no way to tell. As for where else you'd get a battery: Apple. However, now that you've opened your phone yourself, Apple may not consider you eligible for their battery replacement program. I'd still ask, though.

I had sent a fairly comprehensive reply but it seems to have disappeared!

Anyway here is a summary:

1. Apple will not touch an iPhone that has a third party battery fitted.

2. If you want an Apple Store to replace the battery you had better make sure that your iPhone has a genuine Apple battery, so put your old battery back in before you visit the shop.

3. The only guaranteed way to get the CPU back up to speed (1400 MHz) is to have a genuine Apple battery fitted. You might get lucky with a third party unit, but it’s not worth the risk, now that you can get it done for £25.

Hope this helps.

I'm not sure why you're replying to me. I would never have had a third party replace my battery even if I did have this issue. I also pointed out, in the post you're replying to that opening the phone would most likely render the phone unserviceable by Apple. However, I would still suggest asking.

My post was intended to be a general observation to anyone who was thinking about fitting a non-Apple battery to their iPhone. This includes either replacing the battery yourself or by an independent repair shop.

In other words, the only 100% guaranteed way to get a result is to use an Apple Store.

It is great to finally read Apple's official apology, https://www.apple.com/iphone-battery-and-performance/, for this iPhone slowdown fiasco.

My iPhone 6S on iOS 10.3 scored 2506 single-core and 4206 multi-core on Geekbench 4.

I have the same problem with my iphone 6 (ios 10.3.2), so should i change the battery? Phone is one year old

Those scores sound right in line with an iphone 6. So if that is the case your phone is fine. Are you sure if you have a 6S?

Its strange that everything was ok on ios 9.3.5. Problems started few weekes ago, when i updated to ios 10.3.1

Should i hope that new ios 11 will change something? I was very bad decission to update from 9.3.5 :(
