ZMNT (3700mAh Battery for iPhone SE 2016 1st Generation（Screen Size: 4 inches）,(Model A1723 A1662 A1724) High Capacity Than Others Replacement Battery with Complete Repair Tool Kit and Instructions.

The battery capacity is excellent. The instructions included could be much better, but the product is solid. They direction that the adhesive strips are to be used isn't addressed at all. Overall, a very good product but I have only had it installed now for two days. The battery now allows me to use my phone and surf the net all day on a single charge.

I bought this hoping to resurrect my dear SE2016. Instead, I got a terrible performance. The phone works as expected, but the battery will be dead in less than one hour if I use it or three without use.

Watch several "How to" videos, discharge old battery completely, and battery replacement is pretty straight forward. Be patient with adhesive strips under battery. Assembly is reverse of disassembly. I followed the recommended three charges/discharges to calibrate/condition new battery. My only complaint is this took a full week! I sped up the process for final discharge by enlisting Grandson and telling him to watch all the Youtube videos he could stomach. Three weeks later and battery will still last 48+ hours between charges (20% to 80%) as long use is minimal.

The good - The battery kit came with everything that was need to complete the replacement of the old battery. The bad - Unfortunately after 7 months the battery has swollen and pushed the screen out of the bezel, thankfully not breaking the screen. EDIT: contacted the company and they sent out a new battery immediately.

I’ve replaced many iPhone batteries, and have never been disappointed with a cheap battery until now. This is the third battery that has been in my 2016 model IPhone SE, the second being another cheap battery that performed to expectations for several years. This battery has been in my phone for a month and a half, and although the battery didn’t perform as well as I thought it should have from the start, it would at least last the day. Now, after a little over a month of usage the battery performs WORSE than the 2.5 year old battery that it replaced, with the battery monitor reading “service” and the calculated capacity at 72%. The listed capacity of this battery is nothing other than a blatant lie, all of these batteries are the same junk and the quality is hit and miss.

Batter was bought for my old SE (1st Gen) that I gave to my teen to use. Phone is 6 yrs old. Kept it in a waterproof case so the phone still looks new. Just desperately needed a battery upgrade. This battery lasts all day now even with heavy use playing games and watching Youtube. The old batt would die after about 2-3 hrs so huge difference. Deff worth the money. Just watch the how to vid on YT.

Shipment came when they said, packed nicely my grandson, 14, installed it and it has worked beautifully. Stays charged all day long!

Purchased two of these for my Model A1662 1st Gen iPhone se’s. Tried both batteries and neither of them work. My device won’t turn on nor take a charge. nothing happens as if they weren’t compatible. Yet description says it’s compatible with A1662 models. Aside from that seller claims 3700 yet the batteries say 4000. Which one is it? Will be returning these and looking at another company for my batteries.
