How about Apple replacing the battery of Hayes brand?

It's not good to change this battery for Apple's mobile phone. It is best to use original batteries.

Apple's original battery is better, with slow quality decay and long service life. Under normal circumstances, when the equipment is still in the one-year warranty period and the equipment is used for nearly one year, the battery capacity will drop to about 80% of the maximum capacity, and there may be problems such as insufficient battery life. At this time, you can replace the battery free of charge at Apple stores or Apple authorized after-sales service outlets.

Of course, Hayes' battery is not bad. The effectiveness of Hayes quality management system has been confirmed by years of battery production experience and a lot of good feedback from battery customers. In terms of official authority, it has passed the ISO900 1 quality certification management system. The millions of batteries we have manufactured have reached the relevant national quality certification standards, and there have been no catastrophic failures caused by product design and manufacturing, which further proves the reliability of Hayes product quality.
