Same here. I got it from Amazon as an open box “as new,” and it really is like new, but I understand why it was returned: the battery issue. It had 87% charge when I received it. I updated to Synapse 4, updated the keyboard firmware, played for a few hours, and it dropped to about 50%. I then plugged it into a 65 W Samsung charger using a 100 W Baseus USB-C cable. It charged back up to 87% in about 20 minutes and then got stuck there, showing “87% charging” both in the app and on the keyboard display. I switched to wired mode and let it charge through its own cable while playing, and it eventually reached 100%. But the battery drains very quickly even on power-saving mode, which claims up to 2100 hours. That’s about 87 days, so it shouldn’t lose even 2% per day (24 hours of constant use), yet mine drops to 80% in just 4–5 hours . On top of that, I can’t find any information about its charging rate, like you can with phones (25 W, 35 W, 45 W, etc.). I found someone who said they contacted Razer and were told there was a batch with battery problems. I think I’ll return it to Amazon. A €218 keyboard shouldn’t have issues like this. For now, I’ll stick with my 3-year-old BlackWidow V3 until the price of the BW V4 Pro 75% comes down and then I’ll buy it new. €300 new is just too much for me, and knowing it can have these problems is frustrating.

r/razer on Reddit: RAZER BLACKWIDOW V4 PRO 75%

December 24, 2024 -

I bought this keyboard, but I noticed a flaw, I think.
The battery lasts very little. After a day of use, it goes from 85% in the morning to 10% in the evening, both in Bluetooth mode and in 2.5 GHz wireless mode with its dongle.
Is this an issue you’ve experienced as well?

With ARGB fully on? What is the brightness level setting?

The battery inside isn't any beast, so yes, it'll last a few hours if Chroma enabled (and it's set to some higher brightness).

Hi everyone,

I just purchased this keyboard and loving it so far. But my first 3 full charge to 100% is a bit strange in my opinion. Every time i charge to 100%, in a second it goes to 99% and drain to 85% in 20 min...

My settings is what people recommended to not drain the battery as fast as this. I'm on 1000hz polling rate, 50% keyboard backlight and everything turn off or dim after 2 min.

It seems a battery issue more than software, but I'm curious if I'm the only person to experience something like this with this keyboard.

Thank you !

If your laptop is experiencing battery issues such as swelling or poor charging, please replace immediately. Razer Blade batteries are very simple to remove, only requiring a few T5 screws for the back panel. Batteries have a shelf-life and degrade with use, heat and charge stress can speed this up and usually need replacing around 3-5 years for laptops. 2022+ Blades have a charge limiter that should be enabled. For replacements, contact Razer support first, battery warranty is 2 years and outside of warranty they can sell to some regions. eBay and iFixit also have replacements, check your model and year.
