Ifixit battery affecting performance at low power?

Hi All,

I replaced the original battery in my iPhone 6 Plus with an ifixit one and its like a new phone again. All the laggy performance issues I had have completely gone. Mostly.

When the phone is on very low power under 5% the performance falls through the floor; frames missing from animations, apps taking 30-40 seconds to open up then crashing and finally reboot cycles.

Is there a reason for this?

When replacing the battery initially I had no idea it would fix my performance issues, though it does make sense that as the battery wears out its power output would lessen I presume it is a similar situation this time. As the battery runs down its power output dips slightly.

Interesting how this older question came up ...

Looking back, we now know that his was caused by Apple throttling the CPU when the battery degraded or was in a low capacity mode (low charge state). You can read more about this here.

Hi,

I have had problems with 3rd party batteries before but I am no expert on what batteries are good or not but I always stick with the original batteries that Apple makes because I don't want any problems with them. It's worth speaking to ifixit about this and maybe they can offer a replacement or something but I buy genuine Apple batteries from eBay which are used with only a few cycles.

Hope I helped
