"The instructions also don't mention to remove the display, it is very simple if you have done any iPhone repairs before, 5 or 6 screws, remove the connector cover and use a spudger tool to remove the connections."
"A few tips: -Instead of hunching over your table, stack some large books on your table or even use a cardboard box so you can work on it at eye level. -Put the screws and parts in a bowl as you remove them so they don't run away, (guess that's why this kit gives you extra screws.). All the screws are magnetic except the very top-right one, so put all the magnetic screws back in first so you can find that last non-magnetic one. -The top plate pushes against the ribbons so you'll need to slip a finger in between the two halves to hold it in place to screw it back down. Put one of the magnetic screws on the tip of the screwdriver beforehand, ready to go."
"In case you haven't already read the reports, here's why it matters for anyone shopping for a new iPhone battery: - Your iPhone's battery has likely degraded after 2+ years of use. - The battery itself is performing well! For just a battery replacement, you don't actually *need* to do this extra step, but it may make things easier if the battery adhesive is hard to remove later on. - BEFORE removing adhesive strips, use a hairdryer to warm up the back of the case near the battery to soften the adhesive, making removal easier. - IF the battery adhesive snaps and you need to pry it out, use a thick credit card and try to keep the battery as flat as possible, and be careful not to damage the volume control ribbon near the lower volume button, running around the back of the case. - After install, make sure to do a hard-reset of your phone, and follow the battery-conditioning instructions: Let the phone discharge until it shuts off by itself, then charge uninterrupted up to 100% (Instructions say up to 10 hours) and repeat this 0%-to-100%-to-0% procedure a 4-5 times so all your battery cells are optimally primed. --. Personal experience with new battery: --. - I formerly had a "Service Battery" notice on my settings screen and that's gone now."
"I ordered this battery to replace her ~2 year old battery. When you're installing this battery, be sure the ribbon cable coming out of the battery is folded neatly to the side of the battery, so it doesn't keep the phone from seating down properly."

"When I first received the battery, I was getting a pretty poor charge out of it (as bad as if not worse than my aging Note 4 battery). I've been through 2 complete charge cycles (draining the battery completely and then charging to 100%), and am now getting approximately 48 hours of battery life on a single charge, possibly a bit more. I don't normally purchase aftermarket batteries, but this (so far) is absolutely a better buy than attempting to find a legitimate Samsung battery. I don't think Fast Charging is good for the life of the battery (used to heat my Samsung battery up quite a bit, which is not good for batteries)."
"Let me start by saying I took my phone in to my phone provider because my phone would just shut off after being turned on for about 3 hours as if it was dead. I ran across this battery on Amazon put it in and it works AMAZING my phone hasn't shut off yet the battery is keeping charged."
"With her new PowerBear battery she comes home after 9-10 hours at work and still has around 40 percent battery life."
"I just received this battery after my original Note 4 battery would only last 1/2 day."
"It worked just fine for about 3-4 months and then the battery went dead on me. Fine, I chalked this new battery, the PowerBear, up to a "Lemon". I went online and attempted to contact customer support regarding the faulty battery I purchased. They will take your money and I hope and pray the product inst faulty because you are out the money and a battery!"
"when i put the battery in my phone it starts to turn on then the screen flashes and it restarts."

Reviews
"I was looking for a battery case that also used exclusively lightning cable instead of micro USB (and didn't want to pay for Apples). Now for the details: Style: sleek, gradient blue color, covers the apple logo due to its battery. 5/5 (my subjective opinion :). Feel: smooth but is grippy enough to hold comfortably. 5/5. Installation: easy just remove top piece - slide in to case- put top piece back on (it doesn't easily come off unless you pull out the side) 5/5. Battery feature: so far so great. The button when clicked shows how much battery is left, when clicked and held for 2 secs it starts charging the phone and stops charging the phone. Also keep an eye on that top cover piece, the durability, and protection it provides."
"It looks very nice and doesn't generate a much heat if any when I charge my phone with the case on using a 5W charger."
"My iPhone is over 2 1/2 years old and the battery, on my phone, goes down quickly; because I have my screen lit at full capacity and I have many apps that are consistently on."
"With this case I do not charge it at all during the day."
"This was the perfect Christmas gift for my niece who had just gotten a phone for her birthday."
"Plus it's sleek and adds very little size and weight, especially considering that it has a battery inside."
"I'm a full time student and have long days on campus and frequently find my phone battery wears down."
"Case is very sleek and good hard plastic!"

Reviews
"After fully charging the Anker PowerCore 20100, I ended up running my own personal test to see just how many full charges I could get on my Samsung Galaxy S7. (1 Blinking light). The next morning (on day 6), I tried recharging the phone again while the 1 remaining light on the Anker Power bank was still blinking ....."
"Anker PowerCore 20100 – Review by a Frequent Flyer Business Traveler. Most of us would agree that we all carry or own multiple devices in this day and age and they all need frequent (1x /2x/3x times a day) recharging after continuous usage. I obviously own couple of power banks to charge my phone during my flights or at the airports. I always thought it would be great if one these days they made a power bank which could charge all my devices few times and it wasn’t so heavy. The four status LEDs are great and pretty accurate to show the status of battery charge left. Bullet Point Analysis: ------------------------------------. Great For. ------------------------------------.  Business Travelers.  Families on vacation.  Busy Moms & Dads on the go.  Considerate co-workers who want to help colleagues with their charging needs at office =).  College Students on long class schedules.  International travelers. ------------------------------------. The Pros. ------------------------------------.  Great form factor for the amount of battery power it packs.  Power capacity to charge your phone throughout the week (6-7 times).  Accurate charging status and battery level LEDs.  Automatic power off.  PowerIQ feature to automatically route power to the device plugged in.  Excellent value for cost. ------------------------------------. The Cons. ------------------------------------.  None I can think of for what it promises.  May be charge my laptop too =). ------------------------------------. The Specs. ------------------------------------.  Dimensions: 6.5 X 2.5 X 1.  Output: 2 USB/ 4.8A total.  Input: 5V / 2A.  About 1” bigger than Samsung S6 and 1.5” bigger than iPhone6.  Substantially lighter than any other power bank with same capacity in the market.  Capacity is as promised.  You can use your existing cell phone charger to charge the device. ------------------------------------. Summary. ------------------------------------. I think it’s established that in today’s digital and multi device environment our devices are power-hungry at all times. Phones and tablets are more advanced but they need battery juice and manufacturers have conveniently taken spare battery option out of the devices e.g. Samsung. This Anker Power Bank makes perfect sense to carry for all your smart phone and tablet charging needs."
"EDIT 04/2016: Anker reached out to me in private over a month ago, shipped me a new PowerCore free of charge and I confirmed that it was properly putting out over 1A. In addition to this, they replaced an older model PowerCore that had stopped working and I assumed was out of warranty, so I had taken it apart to diagnose what was wrong with it (bad capacitor)."
