Battery Case for Samsung Galaxy S23 Ultra, 6000mAh Rechargeable Extended Battery Charging Charger Case, Add 100% Extra Juice, Not Compatible with S23 or S23+ (6.8 inch) Black

The design of this phone case is sleek and functional, not a pretty case, but it does it's purpose. It fits my device perfectly without adding too much bulk (at that's an achievement on its own since the S23 Ultra is a brick)! Its' construction is durable which provides protection against everyday bumps and scratches.The case can be used as a normal case, and then you need charging you press the back button turning the LED's on (they indicate how much charge is left on the case). The case allows for pass-through charging, meaning you can charge your phone and case simultaneously.In terms of performance, it took me just over 1h30 to fully charge my phone from 12-15%.Overall, I'm happy with this case and I find it useful.

This case is really helpful while travelling. My phone and the case battery were fully charged. It kept a bit longer than 48 hours. Don't know how about others but my phone's battery keeps about 24 hours. Sometimes even less so while travelled I haven't had to worry about charging.However, the case is pretty heavy and personally for me, not comfortable to hold in my hand. Apart from this, the case is useful when planning longer trips👌

Case is very well designed and looks sleek on the s23 Ultra, but it does not work.I tried charging it full power before before use, but even then it only worked for like 5 seconds, and my phone asked me to check or replace my charging cable. I think it wasn't supplying enough power to charge the phone.Update: Customer service reached to me and offered a replacement. This worked, but it still reports a problem with charging cable.My phone at 75% reports it'll take about 2 hours to charge 15%. Not very practical.

Bought in February, worked excellently and can't fault it, but for the last two months the phone has had difficulty staying in the case and keeps popping out, took the phone out to have a look and noticed the battery had bulged out and was causing the phone to rock (and it is obviously unsafe to continue using a bulged battery) 8 months of use isn't bad though but I would've expected a little longer for the price.So yeah, battery life in terms of daily use; great, always reliable and easy to use, battery life in terms of how long the battery lasts before the whole case is for the bin is less than 9 months-ish

Quality battery case which fit well and provides additional charge, also protect phone when it's dropped

The product works well, and fits perfectly. The batery lasts for 2 days.

Took it with me for a weekend away and it was a lifesaver! Had issues with charging my phone so had to switch to this. It actually charged super quickly and wasn't too big or heavy. Going to see if there's an apple equivalent for my mum

All you need for your mobile while on holiday.Phone can be charge more than once. I never used it for whole day but it provides the enough battery charge to the phone for rest of the day.All in all it is a best and smart battery pack for my Galaxy S23 Ultra.
