Bests & Worsts Reviews from Amazon

I have purchased Anker 622, Anker 633 as well as Apple's magsafe battery, tested all 3 and decided to keep this one and return the other 2. 1) Portability First of all, portability is very important to me. I want to be able to put my magsafe battery in my pocket while attached to my phone and I want to be able to hold it and use my phone while charging. Anker 622 and Apple Magsafe are almost the same size and they are both very slim and lightweight while Anker 633 is heavier and bulkier. 2) Power Apple's battery is the worst in terms of power. I tried charging my phone while using it and the battery percentage kept steady and even went down during heavy usage with the battery fully charged attached. Anker 622 and 633 have similar output and charged my phone at similar speeds. It's still very slow when charging wirelessly but better than Apple. When charging with a cable, Anker 633 can give 20W output while 622 only gives 12W but keep in mind that the fuller your phone battery is, the slower it will charge. This is not a battery issue, it's how your phone handles charging in order to preserve battery, so in other words it's the wattage the phone accepts at that time. For example, if your phone battery is at 5%, it will "accept" the max power, meaning 20W from Anker 633 and 12W from 622, both charging with USB-C cable. But if your phone battery is at let's say 70%, it will maybe "accept" just about 11W max so the difference between 622 and 633 is not very relevant. Note that Apple's battery does not accept have an output port to charge with a cable. There's something I found annoying with the 633 model when switching from wireless to cable charging. If I'm charging my iPhone wirelessly at 7.5W and connect a cable, the battery doesn't automatically switch to wired charging. I need to reboot it or detach and reattach my phone in order to switch to wired charging and get a faster charge. With the 622 model I don't have this problem because as soon as I plug in the cable it switches to cable charging. I guess this is because 633 gives you the ability to power off the battery if you just want to use it as a stand while 622 is always on when you have your phone magnetically attached. 3) Temperature As other reviewers have mentioned, Anker 622 gets hot, but mine doesn't get super hot. I haven't had the issue with the battery getting so hot that the phone will shut off. Not sure if it's because I bought mine in October/2022. Apple's Magsafe and Anker 633 also get hot but much less. 4) Advantages of each So, as I have mentioned, Anker 622 is the best in my opinion and it is the one I decided to keep especially due to portability and is also the cheapest of all 3. As of October 2022, Anker 622 is 47.99 while 633 is 79.99 and Apple's Magsafe is 99.99. But Apple's and Anker 633 have some advantages worth mentioning: Apple - Uses a lightning cable, so it can be charged with the same cable you charge your phone. No need for an extra cable but there are rumors that iPhones will be switching to USB-C next year - Shows the magsafe battery percentage on your phone similar to your airpods. On the other hand the battery itself doesn't have any lights indicating how much juice it has left which is annoying. Anker 633 - 10000 mAh which can fully charge my iPhone 12 Pro more than 1 time - USB-A and USB-C output ports to charge different devices. - 20W output when charging with a cable as long as your phone battery is nearly empty - Option to turn on/off battery Summary The choice of which battery to get depends on your personal preference. If you're buying this just to travel and want to bring only one battery with you, the 633 might be a better choice for you. In my case, portability is very important so I'd rather travel with two 5000 mAh batteries rather than carry one 10000 mAh. I normally fully charge my phone battery while at the hotel and then just bring a powerbank to help my phone survive the whole day and 5000 mAh has enough power to do that. I don't want to be carrying a heavy and bulky battery around. Note that there's a new version of the 622 battery with the USB-C port on the side but it seems to be expensive so not sure if it's worth it.
