SAVFY Galaxy S6 Backup Battery Case - 4200mAh External Backup Power Battery Charger Case Cover with Kickstand for Samsung Galaxy S6 G9200 (Black)

I haven't used it much or had it for very long. However, I am pleased with it so far.It's easy to use. (I have only pre-charged it before putting it on the phone, I know you can leave it on the phone and charge it, but I haven't done that yet)It holds enough power for one phone charge.It seems to charge the phone quite quickly.It is a bit bulky, but I was expecting that, so it's not a problem...I can throw it in my bag/luggage with everything else.One other point to note is that it does heat up the phone.

The only thing this case needs is to double up as a phone protection case but as it doesn't go right up to the screen I've taken one star off, it would have had the star for that.Straight out of it's great quality, feels nice - like a suede feel to it. Without charging it I put it on my phone which was at 5% battery and within 30 minutes it has charged it to 68% so I am presuming it is a fast charging case, it also still has half the charge left in the case.Would definitely buy again.

Whilst your phone is in the case and plugged in, your phone and case charge simultaneously so your always sure to have charge in it when on the go.Ours get almost 2 full charges before it depleats so I'm really impressed as that's a lot of charge. Not sure why others are saying such negative things about it as we haven't had any issues other than it does get a little warm when activated. I combat that by either charging in short bursts or ensuring my phone is on a good cool none flammable surface so as the heat doesn't cause any damage. If left in your pocket whilst charging I expect it could cause some damage to the case or phone as some have reported but do you keep your phone in your pocket whilst charging via cable? Common sense stuff really when it comes to electrics you keep them aired not stifled.I am going to get a couple of spares to keep charged for emergency use where more than 2 charges may be required and will be great for holidays and long journeys.

It does exactly what it says on the tin...The phone does get a bit chunky but what would you expect? That's perfectly normal but the product is very good. It would be even better if it had the "fast charging" feature there. I haven't yet used it to actually charge the phone, but on Saturday I was out and about since 9am and was using the battery during a long walk I did. The battery was on all the time and it died at around 6pm, leaving the phone with 100% battery to be used thereafter. Not bad at all as I was using the phone constantly since early in the morning.It's very easy to use and worked straight out of the box.After using it for 4 days now, I've figured it's better charging the case and the phone separately on my desk which is perfectly fine with me.

I brought this for was my samsung S6 as most times i go out when i dont have my power plug or places i go dont have one or westfield that has free charge but lots of people using it and find something to make sure i charge up while out and about. The design is very nice with a stand but somehow i dont know how can you fit a jack in it though as i tried many times with different jack with different size and it wont plug in properley and it comes out easy cause of that bulk button end where you charge the case. Plus im not impressed with how much power uses because i charged it fully and somehow the forth light started blinking but i dont know if it normal ?Plus i gave this a 2 because the person who selling them gave me alots of message forcing me to edit to delete so they can make there product awesome and made me annoyed.

The case arrived on time without any delay. It works as advertised and headphone jack is OK. The downside is the battery capacity as it is not 4200mAh as advertised. Since the galaxy S6 have 2550mAh battery, this case is supposed to give it 165% of its full capacity. However, I found the case is only able to charge it 70-80% so it is just around 1900mAh. The other bad thing it will not allow fast charging the phone when the case is on as the case has input/output of 5V and fast charging requires 9V. It is good for a backup on the go but it have some drawbacks.

Was really good when it worked, but over a month or so began discharging quicker and quicker. Fully charged the case, and then when attempted to use would provide anywhere between 50% and 120% battery to my phone. Great when it worked, but more often than not it was unreliable. Also stopped working after three months of use; it won't recharge no matter how many different chargers I try. The second case I bought is still functional, but also has the sporadic battery life problem of the first one. Overall I still appreciate the device and find it incredibly helpful, but only when it actually works. Perhaps I'm unlucky with the two I've received, but it does make for an unfortunate coincidence. I'm holding off buying another as I'd rather not risk wasting money on something that also breaks within a couple months.

Just got the case, initial impression to follow and will update later on after few weeks of use.Case is solid, bit chunky as expected. Battery indicator light is bright and useful, all buttons accessible. Unit feels grippy to hold with nice material, not heavy, I prefer holding the phone with the case on. Only issue i could say for now is that the headphone jack space is only enough to fit the standard s6 earphone jack, so if you are using earphones that are different (for example i use bose) you need to check and see whether the earphone jack is as narrow as the standard samsung one. Otherwise you can use a workaround like get an earphone jack extension etc.
