Anyone notice a big battery gain or loss from one to another? @768 phone still feels snappy but not nearly as 998. Was just wondering if anyone noticed that big of a difference. And yes I'm undervolted as well ALOT lol

I'm going to assume those are HAVS voltage ranges, but for what freq steppings?
all of them going from the lowest frequency up top to the most at the bottom since higher requires more voltage

I'm aware of that, but kernel freq steppings aren't always the same from one kernel to the next. I'm not keen on flashing a kernel just to cat it's cpu vdd table. A screen shot of the cat would be cool.

I know that it isn't data from his most recent kernel, but here's a piece I did a while back using Chad's current kernel at the time:
Effects of CPU Frequency and Screen Brightness on Power Consumption
It should at least give you an idea how much difference there is between 768 and 998.
For what it's worth I usually run 768 max. I wouldn't necessarily recommend it to everyone, but for 95% of my uses, it's the perfect compromise between power savings and performance.

I still believe that your phone is not as snappy because the undervolt at 768 is probably too low and not pulling enough voltage at that step.
Have you tried raising voltage at that individual step?
FWIW I stopped undervolting a long time ago because my phone went wonky and had to have it replaced. Chad's standard voltages work just fine and it isnt worth saving a few extra hours battery compared to having a stable headset. I use my Inc for business (ditched the BB a long time ago) and need to have it work.
Especially since Fast Charge is enabled by USB. It takes only about an hour to fully charge.

I disagree. His voltages look just fine all the way up the scale. Furthermore, a low voltage wouldn't cause a phone to lag. It would cause it to lock and crash, and possibly corrupt the SDcard.
I'm doing some benchmarking with a stock 4.2 and I'm setting cpu_freq_max and cpu_freq_min at 1300 MHz but when I check cpuspy it shows 1200 MHz and nothing for 1300 MHz. I set the frequencies with No-frills CPU Control and verify them in cpu_freq_max and cpu_freq_min. If I let the frequencies scale then 1300 MHz is used along with the other frequencies.
Have I missed a setting somewhere or is this normal for a stock 4.2?
iam want to know what is the best Note 3 Eynos UV Table for Power Save and best Battery
iam using GoodHannry Kernel V3-A
may you share ur Table to find out best Battery and Power Saving and say ur Kernel Version
My Table is Very Stable

My battery consumption in standby consumes 0.5% / h when I'm on 3g but when I'm on LTE consumption is much higher 1.6% / h, is this normal?
Galaxy S4 I9505 LTE
Rom AntaresOne & Alucard24's optimized CM12.1
Yes.
thanks for the reply
LTE uses a higher frequency so, yeah, it is normal. It also depends on the signal strength. LTE is fairly new so signal may not be as strong as 3G.
I can't find definitive specs on the wifi capabilities of this phone. Specifically which speeds each band supports on each standard (N, AC).
My netgear r7000 is capable of up to 600mbps on the 2.4Ghz band and 1.3 mbps on the 5 ghz.
I have a 155 mbps internet pipe which is over provisioned to somewhere around 175 mbps. I can generally saturate this easily on the 5ghz band during offpeak hours. But usually get somewhere around 80-90 mbps on the 2.4ghz band.
From the router wireless status, the 5Ghz band syncs at 866mbps (900mbps), but max I see on the 2.4Ghz is 144mbps. This explains the speed bottleneck. What it doesn't explain is why the 2.4ghz side is syncing at such a low rate. Signal strength shouldn't be an issue as the router and phone are less than 10 feet apart.
Thoughts?
I think I just found my answer.
Bottom of page 6, remark 1 - https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=2664811
1. 802.11 40 MHz bandwidth is not supported in 2.4GHz WLAN.

Lack of a 40 mhz bw at the 2.4 mhz band is why it tops out at 144mbps (N150) instead of 300 (N300). I'd speculate the reason might be because some of the supported radio bands are very close by (1900, 2100, 2500, 2600 mhz).
This puts one mystery to rest
Good in depth explanation on the topic:
