^^ what roxy said. When you've got a lot of thick wire and big coils it can take quite a bit of power just to get things started, so it can feel a little weak even when the batt is close to full. I'd try going up a gauge to a slightly thinner wire and maybe reduce the coil diameter just a tad to make up for the increased wire resistance, that should reduce the ramp-up

It's not wrong, I tend to change bats at the same level when vaping on the .2ohms range,
If you were vaping at higher resistance the wattage difference from 4.2 to 3.9 wouldn't be that much but that difference becomes huge while going down in ohms
Gut example using a .5 build you are using 5 more watts when fresh. On a .2 build you are using 13 watts when fresh

The diameter of drillbit/screwdriver/etc that you wrap your coils on will affect performance as voltage drops. Wrap on smaller objects to get more concentrated heat. Thinner wire heats faster as others have said. Try a "quad coil" which is your two coils with spaces in the middle so one coil looks like _m_m_ instead of _mm_. That will affect heat and wicking. If none of these do it, bring a spare battery or 3.

How many wraps to get .3

2.5mm diameter 5.5 wraps using a coiling tool. I check it on a reg mod that only goes to one decimal point so it could be anywhere from say 0.27-0.33 depending on how it rounds up. My ohm meter shows me if theres a short but I'm doubting its accuracy lately.

I have the legs rather short and coils close to the posts, well the positive wire close and the negative angled over to get to its hole.

And to the let it ramp up I tried that it still feels cool/weak vapero sounds like he's on to something it's just dissapointing that i'm killing batteries so fast, changing approximately every 2 hours at work

Super-sub-ohming on a mech, 0.3 and below saps batteries and fast. When I was full time dripping on a mech working at a vape shop, I had 8, count them 8, charged batteries on me at all times, along with a charger to charge them back up. Mind you I drain batteries down to 3.7volts when on my drippers/mechs, and that can be 1.5 to 2.5hours of time on a cell, so no it is not unusual that you are draining them that fast. 24awg takes lots of power to heat, drains battery quicker than 26, and 26 faster than 28, also lower the build the faster the drain, more amps pulled drains the battery even more drastically, a 0.3 ohm coil will kill a battery in about 2hours, a 0.5ohm coil will kill a battery in about 3hours.

I'm new to mech mods recently purchased an anarchist tube mod. Running a 25r battery under my big dripper with dual 26g nichrome ohming at .3. It hit's great at 4.2V but when Voltage drops of 3.9 or lower it hits weake than I would like. Would lowering the resistance resolve this by running 24g nichrome?

watts = volts x volts / ohms

basically that translates into:
a 1% drop in voltage will give you a 2% drop in power
a 10% drop in voltage will give you a 20% drop in power (approx.)

Lowering the resistance will drain the battery faster
