Dad originally used a broken screen of 32g millet 5, and then bought a second-hand 6s in January 2019 for dad to use, the second-hand mobile phone bought more than 1,000 times, the remaining 80 efficiency, it is very durable. Just a lot of answers. What to replace the batteries. Finally ask a blogger to change what battery, he recommended the product win high rong, bought a try, he is a plus member, and finally bought 120 yuan battery.
In general, the use is still good, more durable, there are disadvantages, the seller did not send waterproof double-sided tape.
I don't know if the other batteries haven't been used. Personal feelings are for reference only.
To say a side note, the data line of their home is not Apple certification, security is hard to say.
