Battery Case for Galaxy A16/ A17, 10000mAh Rechargeable Portable Charging Case with Wireless Charging Compatible for Galaxy A16/ A17 (6.7 inch) with Carplay Extended Battery Pack Charger Case (Black)

Shipped fast, got here fast. Product is exactly as its described. Works great! Sleek! I would but this again

Between Utube and the kit which, by the way had all tools necessary to do the job, it was easy. New life for an older phone that I love.

The battery is advertised as 3900 mah. As you can see from the test it started out as about 3000 mah on a 100% charge and quickly drained to approx. 2600 mah after only 10 min. of use. (1% per minute) Very disappointing. I have to charge the phone in the middle of the day, sometimes twice. Forget about watching videos or streaming with this battety it will drain quickly. I thought about asking for a refund due to this almost worthless battety but the time limit had expired for a return. So I am stuck with it..if you are contemplating buying this battetu, DON'T. it is only a little better than the battety I took out if my phone. I dont believe that this us a defective one, but that all the batteries perform this way, but I am not sure. However when going through the hassle if taking apart your phone and replacing the battery it is not something you want to do a lot. Very disappointing product.

I like the installation its simple and straight forward. Samsung batteries like to grow and it mine was just not holding charge. This little kit help and fixed that problem with a low cost. The charge is good and the adhesion is strong. Even though I don't use the phone anymore I like to keep it for a spare. Recommend!

Seems to give me a few extra hours of battery life, and that's helpful. Too thick to install in the S6. I can get three sides of the back glass to adhere, but because the battery is about 1mm too thick, one side of the glass remains lifted. Works ok for me because I have a case.

We did the recommended break-in procedure, and it's been working as intended.

nothing special, the original s9 was 3000 mAh and I have seen what would be about a 25% increase in battery life, maybe more. The original battery was also 2 years old on a lot of cycles so that probably explains some of it. The splunger for ripping at the adhesive (if you haven't softened it enough) works very well and is the best one i've gotten from an "included" item in the replacements I've bought, which is probably 5 or 6 at this point. overall nice and easy. it may be bulging the back of my glass a little but i'm not sure if it's just always been that way because i keep spare bills in the back of my case for emergencies and I've just never noticed the 0.5mm it stands out until now because i'm being hypercritical. Also, do yourself a favor and just buy a new back glass for $16 or whatever it costs. Unless you have an actual hotplate meant for this or have done this exact model before, you're going to break it at some point. UPDATE: 8 months, it suddenly has taken a poop and gone to 50% of it's usable charge in the past week.

Battery plugged right in and now the battery life lasts longer than when the phone was new!
