So I started playing this game Order and Chaos Online (kinda MMO similar to WoW) and the temps get very high, up to 41C on WiFi and 43C on 3g. The phone is burning to a point that it hurts my hand. I'm playing aprox 2-3 hours per day, sometimes maybe 4 hours, how dagerous is that to the phone? Can it do any significat damage over time?
I am using the jame bond kernel at 1ghz, which is also a bit undervolted, don't know the values tho, governer is set to ondemand. I tried to underclock it to 800mhz but the game lags sometimes and is a no-go.
ukhm, khm....
Well if the phone is heating up and it sounds pretty bad, I'm pretty sure its dangerous. Maybe not, but IMO it is. My Sprint HTC Hero has over heated a few times and after that it had small little dots on the screen. Hopefully your phone don't fry.

Mines usually sits between 34°C - 36°C, its seems like a normal temp IMO. I've never had my phone hit 41°C before and I sometimes i tether my phone via usb and it still dosent hit that high. If your is hitting that high, it could also be the temp around your home or something. But I wouldn't use your phone to play MMO, especially if your playing 2-4hrs everyday. Just saying..

Well I'm at stock right now because I'm waiting for the ota tomorrow. But I was using koushdecks 1.2.1 with matr1x kernel 4.0 bfs version. Clocked it up to 1.3ghz - 100hz, switched between smatass to ondemand everyone ounce in awhile and I still was at 36°C. I use setcpu's widget to always check my temp and it never goes higher then 36°C. Fact.

Can anyone else pls tell their usual temps, this got me a bit worried. On browsing the net I achieve 38C, on some intensive games I can get over 40C. When idle it usually stays at 30C, sometimes in the morning I find it with 28C. Is this normal?

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.

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.
YMMV

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.
So guys, its a fact we have a small battery for our phone but I was wondering, how do you get the best battery life?
Just post anything! What ROM your using, what kernel, your kernel settings or maybe a tweak you found.
I want this to become a help center for people who suffer from bad battery
EDIT: Also, have you guys expierenced a difference with unfervolting?

Try Greenify in the Play Store. It seems to help for me.
I use a Tasker profile that will disable mobile data when my screen is off and when it's not being used. Don't know if it helps or not I don't worry about battery because I have a a portable battery pack charger thing

I wholeheartedly believe in Greenify! I have it on my tablet and phone. I've seen a jump in battery life by about 30% since installing it. Not sure if you will have the same type of luck or not.
There's many factors that can be affecting your battery. More importantly it depends on the type of rom you are using, assuming it's sense based... Try using elementalx 6.6 kernel, it'll help your battery; tweaked with the right settings. Power saver also seems to help a bit.
This probably isn't what you had in mind but my best tip is to keep my old iPhone with me and use it for media consumption. That way my android always has a full battery for actual getting work done.

Why not just Greenify maps as suggested by others. Did wonders for my battery life, used to go to 15% in the evening, now regularly above 60%. I also use autostarts to kill some other processes that are launched by default
I'm using the stock Android 4.1.1 ROM unrooted. With my normal usage, I can get through two full days. I make sure to toggle off WiFi and mobile data when not in use, as well as toggle on the "battery saver" built into Sense. I also turn off sync for everything (Facebook, Twitter, etc) except for two Gmail accounts which only check for email. It's about on par with my old Nexus One that I moved from. Keep in mind, however, that I just got the phone and these might change, but this is what I've noticed thus far.
A combination of 2xBattery (toggles data connections when screen off) Tasker (toggle data in different times/locations) and Greenify.

When it comes to battery life, the basics really are the most important.
here's a couple:
1. Don't use auto brightness. It tends to keep the display super bright even when it's not needed. The display may very well be the component that draws the most power in the entire phone! Look for widgets that let you select manually (I use "Brightness widget - backlight" from Google Play and even manually, I set the brightest it can go to 79%) or apps that still let you have auto brightness but more controlled (Try "Yet another auto brightness" from Play Store).
2. Use a setup as stock as possible. I know some people are going to disagree with me , but having your phone as close to stock as possible will have the best proven battery life. I think some of the developers here do amazing work on custom roms and kernels, but when people report good battery life you should keep in mind that are so many factors involved that it's hard to replicate it if you want to. Carriers test their phones extensively to ensure good battery life, and while I am NOT saying custom roms and kernels is a bad idea, I AM saying that I believe a stock experience is a more proven option.
3. It also has been proven that undervolting does NOT help with battery life because not only the difference in millivolts is negligible, it may cause instability and finally a reboot, which just happens to be the biggest software-related power drainer.
Hope this helps
im running clearrom 6.5 but i havnt been able to get greenify to work really. when i install it, it only shows a couple apps that i dont really use to begin with. correct me if i am mistaken, but greenify will hibernate/shut off running apps and the apps that the greenify app shows are apps that are currently running?
Correct. If the app you want to hibernate isnt running you would have to run it to add it to the hibernate list.

I don't know if I agree 100% on that one. Undervolting can reduce the amount of heat discharge caused by too much voltage being provided. A hot battery affects battery life both in the short term, and the long term.
Yes, not all phones can handle undervolting (because they're already receiving a good amount of voltage out of the box), and will glitch and reboot, which drains battery.
But, for phones like mine (which I can generally UV by about -75mv without adverse effects), the reduction in heat can only be a good thing for my battery life.
Sent from my Evita using XDA Premium
Heat itself should not cause your battery to drain quicker. Heat is moreso an effect from the cause of something causing the battery to drain rather than heat causing the battery to drain faster. Heat can damage the battery which would cause it to drain faster... so what I mean to say is heat will often accompany the battery draining quickly but not be the cause of it. Hopefully this post makes sense.
Sent from my HTC One X using xda app-developers app
Yeah it's the damage caused by heat that I was talking about. I've heard a hot battery will discharge quicker though. But heat is also a side-effect of the battery providing the CPU with too much voltage, that extra voltage being provided has nowhere to go so that energy ends being dispersed in the form of heat. Which in turn damages the battery.

That is mostly incorrect. The voltage options we can tweak are not enough to make such a big difference, so you can and will still experience heat even with an undervolted cpu, provided the load is the same. And that's my point, that the difference in undervolting in millivolts is negligible yet one reboot can wipe out an entire day's worth of battery life "savings" from an undervolted CPU.
Ok well all I can say is UV'ing definitely decreases heat for me, particularly when playing games (which is when it heats up the most), and I can safely operate without reboots. Before you say it's a placebo effect, I check my temp regularly to verify it.

The battery on this thing sucks donkey balls. I don't know if it's CM10.1 or the NEXT kernel but this battery life is extremely short. Can anyone tell me what their ROMs and kernels are that hold up well to NORMAL usage, not light usage. I don't think my gaming is pretty heavy in usage. I only played for about 4 hours tops and it's drained itself to 38% and I wasn't even connected to WiFi while playing.
On top of that, I've been experiencing more lag than before I flashed the Next kernel. Not even over clocked or using dual boot, I'm also using the hotplug kernel which supposedly makes a difference in battery. I am using a live wallapaper, but it's not really "live" it just changes the wallpaper between two images depending on the orientation.
I've attached the brightness level I used, the screen on time, and the stats.

no, its not undervolting. it sounds like sod, sleep of death. it could be kernel or rom related, among other things. anyways, next time so you dont have to connect to adb, press your power button in for 15-30 seconds, itll reboot.

Undervolting is the most likely culprit for your SoDs. No reason to do it anyhow. Although, franco kernel has had that issue with some releases, but are usually fixed very quickly.
Undervolting will add minutes only to SoT and next to nothing for overall time. It's not worth the trouble it can cause.
Just my opinion....and experience.
guys, while undervolting can affect turning on the screen with a slight delay, most likely its not in this case. and undervolting does not cause sod.

Given that we're using sod as a generic term, I respectfully disagree. It definitely can cause trouble coming from the sleep frequency to the minimum frequency if the voltage is too low, it cannot make the transition. He definitely should roll it back and rule it out before doing anything else. This goes for any instability issue.

of course it can cause trouble coming from sleep frequencies, but it wont cause sod. yes, undervolting can and will cause stability issues, but it wont cause the screen not to come on. it would cause a delay in the screen coming on, but the screen would turn on still.
if it cannot get to 300MHz from sleep, the screen won't come on.

I'm all for anyone doing anything to their device.... That's what android is all about.
But undervolting and under clocking is just something I personally never got. I suppose aside from trying to curb heat issues. But not to prolong battery life. It just makes such a minor difference. I've never seen proof showing otherwise.
But, to each their own.

True that.
I look it it this way. Less heat equals less stress. Less stress equals longer life. Use any analogy you want but the theory is there. If I ever run into an issue with my device the very first thing I do is revert my UV settings. If it persists, at least I've ruled out UV.
I believe the idea of UVing devices comes from an era not that long ago. IE, inefficient processors. Modern(the last two years) processors don't seem to have that much inefficiency. Could be snake oil on my side. It's habit though.
