I have 8 volt cordless gyroscopic screwdriver (please link below). I have had this screwdriver since 7/2019.Â
It seems less powerful and also seems like going thru batteries (a lot more than before). How long do these usually last?Â
I cannot tell it is:
Â
Â
Because the motor is older (has been used several times a day for the last two years) and requires more current (from battery) to perform (which causes the battery to drain q=more often)
Â
                                                    orÂ
Â
If batteries can no longer hold a load. Seems like both batteries would “crap out” at roughly the same time.
Â
I have entertained the idea of a Milwaukee cordless screwdriver. Just that I like the gyro in the Dewalt and the Milwaukee is 4 volts (vs the 8 volt Dewalt).
Â

Any input would be appreciatedÂ
I could very well be the batteries. If you’ve been using the screwdriver daily for two years, they might be getting close to their charge cycle limit. I have two of these screwdrivers, with the two batteries that came in my first kit (found it on clearance for $35 at the PX, and later found a bare tool for about $20). I don’t use mine daily, though.

It seems that a new battery is under $30:  https://www.homedepot.com/p/DEWALT-8-Volt-MAX-Lithium-Ion-Battery-Pack-1-0Ah-DCB080/204475930. Since you use your gyro screwdriver so often, it may be worth the investment to pick one up.
I agree with fm1276 that it would be a good investment to get a new battery rather than getting a Milwaukee cordless screwdriver, considering you are already satisfied with the Dewalt you have
I have bee doing researech. The dewalt is 8 volts and the milwaukee is 4 volts. Milwaukee claims to have lots of torque.
Milwaukee is lees voltage, but more torque?Â

DeWalt sent me a brand new replacement. worked intermittently. found that the contacts (inside the screwdriver handle) were not making good contact with battery. Had to (ironically) use a hand held screwdriver to bend the contacts (inside the handle) so would get a solid contact. I have noticed the DeWalt is not as good quality since black and decker took over. Just hate to spend 300.00 on a Milwaukee when the DeWalt only cost 80.00
For the price ($80 vs. $300), why not just work around the issue. Hopefully bending the battery contacts worked, and my philosophy is to use something until it is unusable. Admittedly, I will get a bit abusive if something disappoints, and have been known to toss or otherwise beat up a tool that isn’t performing to expectations. I think that goes back to my primitive mechanic’s sensibilities: if it isn’t working right, beat it until it does.  🙂

Seriously, though, unless you really need on-demand performance with zero issues, keep the DeWalt and save your money. I don’t know what kind of work you do, but maybe also consider stepping up to a 12v (10.8v) screwdriver. I don’t have the M12 version but can vouch that both the non-Fuel and Fuel versions of their drills and drivers are good at what they do. I do have the DeWalt 12v Max screwdriver (brushed, haven’t bought the Xtreme version yet) and it’s been a favorite of mine for when I need more power than the 8v Max. My DeWalt gyro drivers see almost exclusive use for receptacle/switch covers, battery compartment screws, and other small electrical jobs.
