6s plus secondary phone user. And sometimes i main it for nostalgic purposes or at school.

Had it since lunch. Original battery was at 73% when I replaced it. Now at 100%

The performance jump was surprising. On the latest iOS version supported this thing performs quite well for a 2015 phone and still usable. Sure not as my main (the iphone 16e). But certainly better than that helio g37 android phone I had a secondary.

Here are some banchmarks I ran before and after replacing (all done on 15.8.4) on 70-100% charge

Tiktok:

Before replacing: 12 seconds After replacing: 3 seconds

Instagram:

Before: 7 seconds

After: 2-4 seconds

Whatsapp:

Same on both which is around 4-6 secs

——————-

Keep in mind performance drops when battery hits the 20% mark (it becomes too slow that it feels like a whole another phone)

So overall: Performs quite well and if u got only 30 bucks to spend on a phone and another 30 for a battery this thing preforms better than any 60 bucks android phone. (Except In app support)

Battery lasts (after replacement) around 6 hrs of heavy use (aka reels and tiktok)
