Potential battery savings from txpower adjustments?

I don't want to jump to any conclusions, but it does kinda make sense. I am seeing what "appears" to be a pretty solid increase in battery life during browsing and bulk transfers. I was able to download 3.5gb of data over wifi at about 1MB/s (around 1hr of nonstop transfer, data for Horn and NOVA3) and only knock off 17% of the battery with only 2bars. I am currently at 3:35/5:47 screen-on for the day and still have 68% left. The nonstop pulling is worse than regular browsing, and at this pace getting to the 8hrs of browsing seems like an actual possibility. As I am running on Balance with CleanROM 3.4.4 at the moment, switching to powersave could probably eek out addition gains.
IF YOU BLOW SOMETHING UP DO NOT BLAME ME...ETC ETC ETC
If anyone wants to check this out, and see if it's just fluke, here is what I have tried.
..pre-post revision...I started out doing the changes manually via terminal, but found some resources on XDA and the play store to make it a bit easier, so I am linking that stuff instead. A user has a pretty good guide for the Thunderbolt that I retested with and it works fine.
Just follow the steps here Solved: WiFi TXpower app error issue with missing iwconfig file to get the iwconfig file, and the links for the WIFI TXpower app.
I used Root explorer, so renaming the iwconfig.txt, moving it to xbin, and changing perms was trivial. As for WIFI Txpower, I have been running on 4db(398 DBM) with no really noticeable problems. I imagine it may have a steeper dropoff based on distance, but the plastic strip on the TF700 really fixed the range issue.
..UPDATE: I have noticed that when you turn the device on after a wifi sleep event, it seems to come back up full blast. So my estimates may be off by quite a bit, as I didn't check it between downloads and browsing sessions. Tom make the settings stick, there may need to be some modifications to the init scripts. I just wanted to get this info into the hands of more people to poke at, and determine if this is something worth adding to Aroma for our TF700 roms.

Day one with lots of power switching back to lower levels. Balanced mode with stock _that at interactive + row. Auto brightness.

Looks promising

Thanks for reporting this -- and thanks for trying.
Which interface name does it report in your case -- I get a wlan0 interface name instead of the eth0 reported in the original thread. I just picked wlan0, as it stays there even if I pick "Auto".
EDIT: I used Root Explorer succesfully -- no trouble remounting /system as R/W, so the one fluke I found may reside in the original thread.

Yes, it should be wlan0 for the wireless. The biggest problem is that after the interface goes to sleep (screen timeout), it will come back up at full burn, and you have to turn it down again. It will need to be cook into the ifup scripts to make it survive.

thanks for the tip! seems to be the real deal!
i had a test and notice only the 4 and 11 seem to line up with our tf700's ... is same for you?

others don't seem to change on mine?... and no button for getting back to stock(full power)...

Yes I think we really just need to call true power via dbm to be accurate. The wifi power app was a quick way for people to validate what I was experiencing. I want to do some more playing around over the weekend and maybe a mod for cleanrom to handle the sleep issue. I am seeing a pretty significant drop in power drain while browsing and doing anything with wifi. I am having to force usage patterns to drain the battery versus just firing up a browser or online game.

You can use the command line to change the parameters. Use "iwconfig wlan0 txpower 1"to get down to 100dbm. Which works great as lo g as you are near the router.
"iwconfig wlan0 txpower 15" brings you back to 1496dbm

I am running this now with lowest settings for almost 24h.
I am not seeing any improvements in battery life.

It currently resets on (at least wifi) sleep, so you shouldn't be seeing any improvement unless you kept your poor 700 awake all those 24 hours.
The criterion is the "screen on" time, which may well be longer with the mod in place and active. Don't forget to activate it every time you wake up the 700.

I'm not sure when it was incorporated, but I know the 'Wi-Fi optimization' option in the advanced Wi-Fi settings effectively does this dynamically. If I recall correctly, it showed up after the last stable release but I've certainly noticed a big difference in battery life since I keep my Wi-Fi on always.. and no need to iwconfig depending on how much traffic you're planning on pushing! Anyway, it would be under Settings -> Wi-Fi -> (Menu) -> Advanced -> Wi-Fi optimization and that seems to do the same sort of thing and takes into consideration some of the weird PM issues related to the hotspot AP code. Just my two cents though..

Yes thank you, but that was mentioned earlier already and I took it into consideration and switched back on every use.
I have 6h screen time with reduced tx settings as well as without.
Really no effect here. I also reduced to 100dbm.

The Wi-Fi optimization option is not available in stock roms. I think that this is essentially what the non-Asus roms are doing with their wifi. The problem is that none of the non-Asus roms have made it to the 100% functionality mark, compared to something like CleanROM. If the day arises that they do, I would drop the stock rom in a NY minute, but until then, they are not complete replacements for me.
That being said, will you conserve power via wifi when running a aosp rom with these adjustments, probably not, but the aosp roms have never given me the battery life of CleanROM to begin with so it balanced out. I am having no problems breaking 8hrs screen on time with a stock rom and wifi adjustments.

No disrespect intended, but I doubt it is zero. It may be minimal and contingent on usage, which is why the feature is available in aosp roms. I doubt this is the optimal way of using it. What I can say is with my usage patterns I was getting an average of about 5-6hrs absolute tops on balanced with stock _ that kernel and auto brightness, and now I can normally get over 7of heavy browsing consistently.

Whether it is 0 or 1% doesn't really matter for me. What matters is that is practically has no impact. I tried on 2 transformers now (one with CROMI and one with stock).
So it would be interesting to see the difference and see why your prime has significant power savings and others not
Unless there is some movement I will throw iwconfig from my tablets.
Anyway, thanks for trying.

I'm not using a Prime this is the TF700 Infinity forums. And feel free to toss it from your tablet though every other none stock rom includes it for a reason. If you have nothing further to add other than "my smartassv2 cfq hundkernel undervolted overclocked device doesn't magically have 10hrs of screen on time", please dismiss yourself from this thread. All devices are not made equal, and maybe your particular device(s) are not effected by these changes.
What is a fact is that different people have different experiences with these devices, some perform better than others in different situations. What I can state is that I am able to consistently get over the previous 6hr average, with my specific device, by babysitting the txpower.
I posted this information FYI and YMMV, so can we just leave it at that. If it is irrelevant, and doesn't work for anyone, the thread will age off of the page by itself. Thanks

Welp, that escalated quickly.

Wi-Fi Optimisation Option In WiFi Settings.

Hi all,
Not seen a thread for this yet. Believe this is new to the 4.2 update as this option never existed previously.
In the Advanced Settings Menu for Wi-Fi you can see this box and it is checked on by default.
Can anyone with the ability verify what this does potentially? Might be useful in future development possibly?
Furthermore, I wondered that with all these TF700 Battery Usage threads there may be a potential error somewhere with the settings that having an adverse effect? This probably wouldn't be the first time something like this happend with ASUS.

Edit:
Side not noticed while trying to do some crude testing of this that there is a SIGNIFICANT improvement in battery life by turning brightness to SUPER IPS+ and then move the brightness down to a comfortable level,due the the extreme brightness the level can be very low 10-30 % and still easily bright enough

The battery drain is only proportional to the final brightness.

It gives your wifi adapter lets power, which in return, shortens your wifi range, but decreases battery consumption because I usually could walk around the house with full bars, but now its on optimization its quite a bit shorter, get 1-2 bars at most on porch(cheap router lol) but used to get almost full on 4.1.1 without the "optimization".

I truthfully dont know if you can decrease it, but there are apps to make your wifi range expands, which consumes more power but I would not tweak with the power, just either turn it on or off. It is there to help, Before there was no option so it can only help battery life.

2.4 GHz Wifi Performance

I've noticed very poor performance when using 2.4 GHz wifi on my G3 when compared to other devices. I can have my Nexus 4 and G3 sitting right next to each other on 2.4 GHz WiFi and the G3 is consistently slower when doing a speedtest like speedtest.net or iperf. Usually the G3 gets around half the speed of the Nexus 4 or worse. On occasions i've seen the G3 start getting below 1 Mbps or nothing at all and the the only way to fix it is by putting the phone into airplane mode and taking it back off.
When the G3 is connected to 5 GHz it is pretty much on par with the Nexus 4 when doing speedtests. I've also not seen any of the strange slowdown issues that require a reboot or airplane mode toggle on/off when connected at 5GHz.
Makes me wonder if i got a defective device or if anyone else is experiencing the same issues. I'm still within my 14 day return window but i'd hate to go through the process of swapping out the device and tweaking everything back to my preferences if this is an issue that will likely be fixed with a software update.
Has anyone else noticed issues with their device when connected to 2.4 GHz wifi?

You select the frequency when joining the network. If you have a dual band wireless router and have both frequencies broadcasting, the option to chose which band will appear when you are searching for wireless networks.

Verizon was nice enough to recently upgrade all FiOS customers with symmetrical bandwidth. Your upload now matches your download and in my case exceeds my download for no additional charge.
Not quite as fast as Google Fiber but Verizon's highest package is now 500 down/500 up.

WiFi strength, range, and throughput

Rate this thread to express how you think the Huawei Nexus 6P's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!

WiFi strength is good...nothing spectacular.

Good wifi.

Works pretty good. Pick it up outside in my car from my parking spot. Not strong but still connected.

Wifi is great here....... @svetius how are you doing Sir.........long time

I don't know if it's my router (I just bought it 2 days before my phone came in) but my download speed is not very good. I have a 50mbps down and 25mbps up, but when I run speedtest I get anywhere from 1-30 down and always 25-30 up (normal). My upload is always fantastic, but down varies greatly. I don't know if it's the router or if it's my phone. In all situations I am less than 10 feet from my router.
Can anyone run speed test on 2.4ghz and 5ghz bands and inform me if they see odd download speeds? By odd I mean jumping up and down a lot.

Couldn't agree less, the wifi reception on this phone is worlds better than my 2014 Moto X, I'm getting 2-3x the bandwidth at the furthest distances in our house.

Substantially better range and throughput than my N6.

Find my wifi is good. No better or worse than all my other devices. Picks up where i expect it to and loose it where i expect it to. Again speed is on par with my other devices

Wifi on 6p is much better - get full 118Mbps download (cable limit) with Nexus 5 typically doing 80Mbps download at same time frame. Connected to router at 585Mbps but I have seen it a 7xxMbps rate to router but effective internet still cable limited.

I also am getting faster WiFi performance by a good amount WHEN I do .. reason saying that is that the results are very variable. I would like to attach a screen print I saved but do not see how.

Great throughout with alright range, wifi drops at less range than my Note 3 and S4. This based off two N6P, first device I returned as the auto rotation was broke.
Sent from my Nexus 6P using Tapatalk

My WiFi has been significantly better than my s4 so far with better throughput, latency, stability. My home connection is consistently above 500 Mbps.

First image 5ghz, Comcast 105-150mbps depending on time of day. Second image is 2.4ghz

WiFi is infinitely better than my previous phones, and 5ghz AC works better than on the iPhone 6s plus in the same spots. Signal strength on 5ghz AC is always 5-10db weaker than 2.4ghz. Plus, I get my full 90mbps everywhere in my house with 5ghz. 2.4 caps around 50-70 because of no free channels. Huawei did something right with the antennae, because I have no issues ever with signal/speed.

I'm getting lower pings and faster throughput on my 6P than my iMac 5K!
Of course, the position of my iMac may make a difference - but, regardless, that's bloody impressive. Huawei has always been pretty good with antenna design, and the larger size of the 6P presumably also helps?
In a test just now I got 9ms, 7.6 Mbps down, 1.1 Mbps up on my 6P (connection 526Mbps) and on my iMac 19ms, 6.8, 0.8 (connection 527Mbps*).
(* bit odd that one is 526 and the other 527 - maybe a rounding issue as I assume they're fixed increments?)

I'll second that WiFi speeds are noticeably faster than they were on my N6.
I haven't done any actual testing, but the primary thing I've noticed is that transfers to my local server are typically 20-30% faster.

On 5Ghz I got 72.2Mb down and 19.6Mb up on a 72/20 connection, so its running it flat out. This was through the speedtest.net app.

The signal on my 6p is significantly better than my Oneplus one. I tested both where wifi signal is lowest and tested both 2.4 and 5ghz bands. Pings are almost identical.
6p
5 ghz - 64.81 down / 12.19 up
2.4 ghz - 57.91 down /12.25 up
1+1
5 ghz - 30.70 down / 12.22 up
2.4 ghz - 17.30 / 12.16 up

Constantly drops Wifi. Then often forgets networks and even can't see any while scanning.

Honor View 10 : Slow bandwidth (4G and WiFi)

Hi all! I've been looking for some answers but without success. So here is my question, and hopefully I didn't miss the answers somewhere in the forum
I have a Honor View 10 with the latest updated (Android 10). I noticed that the device's bandwidth seems very slow (between 0.5 and 1MB/s download in 4G with full reception and between 1 and 6MB/s in WiFi, 1 meter away from the WiFi spot at home).
In the same conditions I get around 3 to 5x more bandwidth with an old iPad mini 2
Rebooting the V10 or going on plane mode for >15 seconds doesn't help. The bandwidth isn't stable, sometimes it's better sometimes a lot worse.
Question : is there any bandwidth limiter that activates on these phones when they get old?
I think I checked all the usual issues that could explain this problem. The 4G bandwidth could be bad for a ton of reasons. But what I don't understand is how any Apple product seems to have at least 10MB/s bandwidth on my WiFi, while this phone sometimes drops at 1MS/s (same conditions, less than 1 meter from the WiFi spot)
Thanks in advance for your replies
