We strongly recommend that you watch the corresponding installation video on YouTube before replacing the battery. 3. Please install carefully. Avoid puncturing the battery, which may cause battery expansion. 4. If your phone constantly restarts and the logo flashes or is not charged. Probably the connection of the ribbon cable is poor. Please re-insert the ribbon cable, check the connector and clamp it firmly. 5. Please make sure to fully charge and discharge your new battery 3 to 5 cycles. 6.

Review: Will damage your phone - Not recommended. Immediately after I installed my phone stated battery not verified. Then it started freezing and restarting in cycles of about 3 minutes or so. Apparently I searched internet and found similar scenarios on reddit saying it shoots surge current on charging port. This battery gave me a huge loss I regret purchasing because the old battery was still good at 85%. As I type, I have a new phone the iphond is dead
Review: Bad Battery - I bought it 3 months ago and now I have to buy another battery, it no longer holds the charge and turns off the phone very often, I think that for three months it should work very well, very bad product and very low quality,
