Swaller Battery Case for iPhone 7 8 6s 6 SE 2020/SE 2022, 3200mAh Portable Charging Case Rechargeable Battery Pack Charger Case for iPhone 7 8 6s 6 SE 2020/SE 2022 (4.7inch) (Pink)

This is an excellent charging case, and it is exactly as described. It held enough charge to charge my phone at least 4x during the day, charges up fine during the night, and it allowed me to get around easily enough for what I needed my phone for. I was thoroughly pleased and very satisfied with the product. Having now owned this product for a full year, I have continued to be delighted by how well it functions.However, in the past 2 weeks, the charging port at the bottom has become more and more difficult to get an adequate connection with the charging pack. It is not the connection between the phone and the case, as the case continues to show issues in charging even without the phone being attached. I have only been able to charge it by putting the phone charger into the port at an exact specific angle, and then taping the cord to the phone case during the night so that it would be able to charge. Even this is not error prone, and I the charger pack has been dying on me during the day, which is a headache.All this to say that this is a great product for up to 1 year, but doesn't have the durability for beyond that time.EDIT: I changed the review to 5 stars, because of their excellent customer service and because they honored a 12-month warranty and replaced the defective case with a brand new one.

I had high hopes this would behave like an external power pack and provide power constantly until it runs out of juice. During my first week, I had several problems with the battery pack that made me regret my purchase, then it suddenly stopped charging my phone at all. Below are my grievances:1. Connector makes intermittent contact with an external cable. Not a big deal if you are constantly holding the cable on to the power pack or setting it down perfectly, but becomes problematic when actually using the phone while charging2. Once my internal iPhone battery reached 100%, the battery case would stop providing power, so when streaming videos, I have to constantly tell my battery pack to start charging my phone again, causing extra wear on my phone's internal battery. My external power packs don't exhibit this behavior, and constantly powers my phone when connected. Seems like the battery case has some room for additional design refinement.3. When plugged into a charging cable, the battery case would only sometimes charge the battery pack while simultaneously charging my phone. I didn't think too much of this since other external power packs don't simultaneously charge and power either, but it seemed like an oversight on a product that doubles as a case.4. Initially, worked OK with my vehicle's carplay feature, but soon started to lose connection with my vehicle, especially when my phone went from charging to non-charging mode. This tells me that I am not allowed to reliably use the battery case while simultaneously moving data through the cable.5. Battery case stopped charging my phone at all after 10 days of use. It would take a charge just fine, and went from two charging lights to all four, but would still not power my phone at all.This battery case looks and feels high quality, but a bit bulky and heavy, and would've willingly given up battery capacity to make the case a bit more svelte. As far as functionality, this case has so many quality control problems on a product they had over 4 years to perfect, that I have doubts about it's ability to avoid critical battery failure. You want a product carrying Lithium Ion batteries to be more than "somewhat good quality", and this product completely falls short of even that. I strongly recommend against anybody purchasing this product.

***Update*** After leaving my original review the vendor contacted me and offered to send a replacement. Unlikely the original battery, when I plugged this in, the phone did start charging immediately. I'm not sure if it will die out early and will post results here. My takeaway is that you can get a bad battery, so if it isn't working contact the vendor for a replacement.Original Post: I already had a good battery pack that worked (HETP version). The problem was the case was completely solid and I was hoping for one I could swap out without risking damaging the phone. Also, the cord for that one kept falling out.This one was much worse. I would wake up in the morning and the phone would be at 30%. What I believe was happening is it would charge the phone and the case, but then once charged it would not charge the phone any more, so overnight all the little pings to the phone would drain it. So this may not be a problem for you if you turn off your phone or don't have as old a phone as mine.However, then it got worse, I woke up one morning and it wouldn't charge and it was very frustrating have a dead phone on my bus ride to work. Anyway, I would highly recommend the other one over this. I'm still giving it two stars because the battery worked well and it might work for others.By the way there seem to be a lot of fake reviews and posts on this. I'm not sure I would believe them all.

Phone case works, it holds a charge and fit the phone very well. I am rough on things, and this protected the phone well.The issue comes from the charging port, it wore out on mine (6s model) and became very loose. It got to the point that it was difficult to charge the case and subsequently the phone. It lasted a few months, before I had to just take the phone out and order something different. Like I said, I am rough on things, but the phone itself still has a very good and firm charging port and I have owned this same phone for several years.it does its job, its just not a forever solution.
