So I've had my Touch "enhanced" for a bit over a week and I'm having some annoying issues regarding battery life. I'm charging this thing once at least once a day, twice a day when I'm using it a bunch. I've messed with the power settings, and the phone goes into standby after 2min. The only 3rd party software I have is touchpal, everything else is factory. I was just trying to gauge some input from other users. I did call HTC, and was greeted by an ass of a warranty tech, who, after getting my problem explained to him proceeds to ask me what I want him to do. Wow. Then he tells me that a new battery won't be instock for two weeks! How frustrating!
Thanks in advance.
You should get at least a day even with medium-heavy use. Up to two days on average.
If you install the excellent Chi-Dai Battery status plug-in then that will monitor the power drain on your battery. It will tell you if the problem is software or the battery itself.

Thanks, I was about to download something to moniter the consumption. I'll give it a shot when I get home from school
I have the same issue with my battery. I use it for med-heavy. By the end of the day Im at like 15%. That sux.
I've installed S2U2...does this application drain the battery also?
monitoring your battery life won't do anything when you want to increase it
if you want to save battery life
it's likely that you have your wireless radio's turned on while they don't have to be,
go to your comm manager
WI-Fi drains A LOT of power and should be on only when you plan on using the internet
your GSM phone radio can also be turned off, useful when you're not in an area covered by your carrier when this happens your device panics and sends out signals to connect to the antenna tower this extra cell phone activity is bad for your battery life... and your sperm count
bluetooth takes an insignificant amount of energy to power
lastly pressing the lock button on the device is useful because it turns off the screen but keeps the device on using these features allows me to have my device unplugged for 2 days

2 DAYS UNPLUGGED? Are you kidding me. On standby or using it. Im thinking this battery is horrible. If I dont plug in every night, im in trouble.
If you want to increase the lifetime, use Battery Status software and activate CPU Scaler, it's great!
Before: I used only 201Mhz freq, my battery had a lifetime of 1 day using it normally.
Now: I've overclocked it to 260Mhz with CPU Scaler activated (low: 99Mhz, average: 201, max: 260) and my touch can stay 3 days without charge need.
I still use these settings but I have a unlimited data contract with my operator, so my touch is connected all the time to Edge (push mail and weather updates), and with these settings I have to charge it every day. Don't care about this since I work with a PC all the time.
I think if I used all the time the original freq, I'd have to charge it more often...
CPU scaler
I have Battery Status ver. 0.5 but don't see CPU scaler, is it only available in the Beta version?
1 to 2 days of life with normal-full use. Up to 4-6 days in standby with almost no use

Can you please give me more info on the battery status software and cpu scaler?
Do you have an Elf or Elfin?
I've an Elfin.
Battery Status is a today plugin you can configure and use to overclock and set CPU Scaler.
Here is in attachment the version I use
Overclock and CPU Scaler are only available for OMAP processors, so for Elf/Elfin it will work.

I turn off the wi-fi when I'm not at home. I'm always within service area, so the GSM radio stays. I don't use bluetooth. It's set to go into standby mode after 2mins. On Thursday, I took it off of the charger at 8:30am had a couple classes till 3pm, so light-to-medium use. It was dead by 3:30pm. I did install BatteryStatus later that night, and figured out the scaler, and it helped the next day. But honestly I shouldn't have to underclock it in order for it to last even a day, a bit ridiculous to me.

I have a Touch enhanced, and am using the CPU scaler just dandy. Just play with the settings a bit, and you'll get the hang of it. Try LOW:100 and HIGH:234, to start out, then go from there.

Visit the Kaiser forum. We're having the same issue. GPS seems to be the problem with me. As soon as I turned on GPS, it sucked my battery 5% in 5-7 minutes. Then down to 73% from 97% in 3 hours.

I didn't configure anything particular, just installed it and set the overclock and CPU Scaler.
I talk an average of 2 hours daily. Since 6 am until 8 pm. I always get home with 15% or less. Using batt status with omap overclocking to 247. Average use of pda also.

Right on brotha. It worked great! I was wondering whats the lowest low you can use to conserve battery? Im at 98-low 247-high, using CPU scaler.

Im on 87/201/247 and boost to 260MHz, everything works fine, only some flickering when it runs on 87MHz..
But the battery life is quite good as it lasts for 2 to 3 days (light to medium usage, some texts, some phone calls, seldom Wifi)..
I have to say that the stock battery lasts much less then the one I got from Brando.. although the amperage is the same
I finally use xcpuscalar only for conserving battery, not for overclock. In another threads some people suffering from spotted, patched even broken LCDs and I do not take the risk to overclock Elfin because of possible overheat of the CPU and the CPU is most likely very close to the LCD due to the thinness of the Elfin. If the CPU is hotter overclocked than it is on normal speed it could cause spot, patch or even damage on LCD. This is my opinion.
Xcpuscalar is able to downgrade dynamically the CPU speed against Batterystatus which is only able to set one speed for the CPU, that's why I chosen xcpuscalar.
It seems to work fine even after soft reset... but 87MHz is very slow for me... it speeds up very sluggish. I use 169, 182 and 195MHz settings.
Will see the energy spare on the battery.
1. Dont set any of them higher then 1075. I've found that on multiple HD2's that higher then that causes instability because the chip doesnt like to be pushed that hard.
2. I have my primary profile set to 1075 max, 614 min, and getting good results.
3. Set your primary to interactive, and all profiles to interactive EXCEPT your low batter profile.
4. Add these profiles:
Temp >
Charging/Full
Batt < then
Screen off
-Temp > Set the temp around 40 degrees C. Set to interactive. Max around 576, min to 245. Reccommend auduable warning on. Priority to 100%
-Battery <. Reccomend you set to around 30% battery. Powersave mode, max around 576 or so, min at 245. Priority at 90%
-Charging/Full Max to 1075, min to somewhere in the 500 or 600's, or higher if you want. Interactive, and Priority at 80%
-Screen off. Set max to 576, min to between 300-450. DO NOT set min to 245, as this may cause a screen freeze when it tries to wake up. Interactive, and priority to 50%
Thus far, this combination of settings has, on the multiple devices i've been playing with (about 6 total at the moment) is giving the best battery life, and the least amount of screen freezes on wake up.
Thanks for sharing these. AFAIK setCPU is quite important to the stable and productive (sans improved battery life) of Android on our beloved's.
Personally, I've taken to 245/245 for sleep mode. I haven't noticed a "groggy" wakening, but maybe I'm alone here...otherwise I like your settings.
Thanks again for taking the time to post.
android can run perfectly at 650+ mhz max, 245 min

I used to use 245/245 on sleep, but noticed a 4-5 second delay on one of the devices.
Actually, that may have to do with your SD card itself. my phone (running Bangsters 1.3b build) has a rare delay on awake, and a class 4 card.
Another HD2 running darkstone has a consistant delay, 245/245 and its running a class 6.
And still another has no delay, and is set to 245/245 but the stock non-speed rated SD card..
I have constant screen freezes on any build i use. bangsters1.3b has the lowest. it only freezes when i am in a phone call and the screen turns off. It lasts for about 15 seconds to 1m. then recovers. makes for some interesting post ended phone call conversations.
Trying your settings, MadRabbit.
Will give it a try, thanx
Should be better if we post our impressions so far within 24 hours

ill give this ago i dont tend to get slow wakeup problems but i do how ever get screen freezes so hope this helps as when i playing a game it can make it really hard to attack people when screen isnt picking up my figures
What exactly is the interactive governor? And why not set the mins to 245 so the processor is scaled down when its not being used?

Minimums may cause an issue with the phone when it wakes up from sleep, especially if you have a higher class memory card.
I've noticed that my usual drain became slow during last hour, I'll report better news tomorrow, leaving device in stand-by at 69% battery left.
Ok, i didn´t think i was that stupid at this but now i don´t know anymore
I´ve searched both in andoids market and on the XDA app on the phone but i can´t find the app setCPU.

From 69% at 12.15 AM, battery dropped to 61%.
That's what I've seen when I press the home key at 6.45, cool :;
thanks man! just tried your setting, and then used current widget to check : 4mA when the phone was in sleep mode. This is the lowest result i've ever have ( i got 7~9 mA before)
ive ran this setting today and battery its definitely draining slower... ill report in a few days of using these settings...
I use it until this morning and I find that very good.

Thanks! I will try your settings, mine were a little off and gave me 45mA in standby One question though, what sample rate do you use? mine is still default (50000).
I have setCpu 2.03 installed but i can't find the Interactive setting?
Where is it, or do i have the wrong setCpu version?

I'm on taiwan 4.1.1 stock
same problem here, i am stock OTA 4.1.1 (india)
download CPU spy to check and make sure it's still going into Deep Sleep when the screen is off.
Also if your rooted use No Frills CPU (or any other CPU tuner type app) and change the governor from interactive to hotplug, hotplug disables one of the CPU cores when not needed thereby saving battery.
Even for me as well and so many issues so many things missing in the update like
1.Screen capture app is missing.
2.Lock screen is stock in portrait not turning to landscape unable to solve it.
3.Battery is draining so fastly as compared to before.
4.All the apps not responding instantly it is taking time to respond and even i need to reopen it as it is not opening for long time
5.Main thing is Notification bar is too small compared to before and unable to see signal info properly
6.And the home screen seems more crispy i didn't like it at all
and finally before it looks like a tablet now it look like a phone in considering with the notification bar and typical buttons like home screen......

Daniel, it is going into deep sleep.. It's driving me crazy the way it still uses up battery..Also like said by others,notification bar is too small..Can not read anything on it (battery percentage, wi-fi signal, notifications..)..Any other ideas?
I saw massive drain after I installed the latest Samsung push service update. I unistalled the update and everything back to normal.

Disclaimer; This does not damage your phone at all or fry/mess your cpu.
This method is used to lower CPU stress and increase Battery life
This method works for all rooted phones.
IMPORTANT: The newer versions of SetCPU might prevent your phone from entering deep sleep. Download version 2.24 from the following link which is the one with no problems and completely works 100%.
LINK
Deep Sleep breaks when charger is plugged in, you can see this by CPU SPY application available on playstore
Stop Downloading Battery Saving Applications, they do nothing and uses RAM.:silly:
Also Turn BLN off when you are sleeping.(It also Consumes battery and sometimes prevent deep sleep of CPU)
Set your Brightness to minimum and disable auto brightness.
LINK to Display Brightness
Instead use lite app called - Display Brightness from play store.
Turn off wifi and mobile data when not in use.
Use toggle for auto rotation, and keep off when not needed.
For more battery Saving, disable all animations and set screen timeout to 1min.
The S plus sucks in battery life. We all know that.But here's a fix, Try Under clocking instead of Over clocking.
When screen is on:
MAX 1.4Ghz(Why to OC??, if your phone runs smoothly on 1.4Ghz)
MIN 192Mhz
Ondemand governor (This governor jumps up to max when needed but spends most time on the min freq. Best battery saver.)
When screen is off:
MAX 365 Mhz
MIN 192 MHz
(This prevents lagging when playing music and other activities when screen off)
This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!
NOTE: Turn off Autosync from the settings. It's only used to sync your gmail and contacts and such. You can manually sync when you add a new contact and since I don't use gmail, I refresh manually whenever I do.
SetCPU:LINK
Specific instructions for those that can't get it to work!:
On SetCPU:
Click Add profile
Where it says Profile, select it and tap "Screen Off"
Set the frequencies you want in use while screen is off (If you want just one frecuency, put both sliders on the same number)
Set priority (in case you have other profiles, otherwise don't bother)
Select governor (Won't really matter since cpu is gonna be running at 1 frecuency)
Tap save
Go back to Profiles tab at the top, then tap Enable at the top left to make the profiles work.

To check if its all working, install CPU spy from the playstore: LINK
For Playing GAMES(HD)/HEAVY GAMES, Plug your Charger in and play if possible.:good:
Most Important thing is to calibrate battery,
Calibration of battery is needed when you change your ROM.
This process wipes batterystats.
Battery Calibration
1. Charge 100%(NON STOP)
2. Download any battery Calibration tool from play store; (Link to App)
3. Open that app, click battery calibrate
6. Unplug your charger
7. Discharge your phone down to 0% during the day
8. Charge back up to 100% (NON STOP)
This is to make sure you're using your battery at 100%. Only do this after you flash a new rom.
The worst battery killer is 3G. No matter how much you try to optimize battery by tweaking and underclock, if you have 3G on, you're gonna have a bad battery drain.
Make sure that Autosync is disabled.
Done A small test usage 14 mins , you can see in attachment your CPU should look like this.

Don't get apps that take background processes like what xellar said, facebook, and some other apps like tap tap revenge 4. Anyways thanks for the tips and link to free setcpu
Other people can also share VALID ideas about saving battery.
Will help many users.
Nice advises. I'm already using these.
One more good thing is turning mobile data off whenever you are not using it, also bluetooth, lowering brightness.
Good app for doing so is Power Toggles. You can always have widget on home screen and switch on/of these things with one tap.
Riiight.. Turn off autosync, disable 3G and wi-fi, dont use apps or games.. I might as well buy Nokia 3310..my phone lasts easily whole day with wifi on..with 3G it can get me at least 6-9h which is fine.. The key is to turn off 3G when you are on wifi and turn down brightness.. Everything else is not using your smartphone smart..
1) Set your network mode to 2G only if you're not using 3G/WCDMA
2) Manually set your operator in settings.
PS: After flashing one of firmwares I got a bug - battery is not charging to 100% while phone is ON. Only to 99% and not showing a message about fully charged battery... But when the phone is in off mode - it charges to 100%. Anyone knows how to fix this thing?

If profiles are not used it exits and there is no use of RAM in both versions (But then you do not have the unique feature of auto switching profiles ).

But it has no profile-autoswitching, in fact no profiles at all. Voltage control Extreme has at least profiles, but without autoswitching. What is good about Voltage Control Lite/Extreme is that it sets cpu setting with init.d and so the app does not have to start on boot
Yes that is nice...

Many thanks for the battery saving hints. I'll finally kick out the Task Killer App, doesn't really seem to do anything except creating problems ..
For the statement that Underclocking would help in saving battery I wouldn't fully agree. A slow cpu needs more time to complete a task before returning to a sleep state. Of course the battery drain is higher with a higher frequency (which also require higher voltages), but I believe, that there isn't much to gain on this front. As long as I don't see any profound evidence I'd even suspect, that an underlocked CPU overall could even cause more power consumption. You can also read more opinions about this in general in this thread.
Much more beneficial would be to identify those apps that cause frequent wakelocks. Does anybody have hints here, how to track down those 'bastards' ? (From my Linux I know 'powertop', does something similar exist for Android? (Or are the battery statistics in CM10 sufficient to decide which app to wipe?)

Your above sentence about UC comes true for heavy usage.
Normal apps can run smoothly and at same speed as of OC.
My Son's Nexus 10 had served its purpose. But Started to die at Random percent, Mostly above 50%.. So Got a new Tablet for him. But Did not want to throw away this Gem of a Tablet.
After weeks of Trial and Error finally found a solution Thanks to input from a Redditor.
Issue/Problem: Dies at Random % showing battery %0 and Shutdown. But In Recovery with Full Brightness it does not Die for hours.. (as later found out.. Recovery does not need much CPU power)
So What did I try:
1. Changed Rom's (All the way from Base Google Images to Oreo) >> Did NOT fix the Problem
2. Clearing battery stats.. etc. ( incl completely discharge and Charge and all those cycles usually we do to calibrate the battery) >> Did NOT Fix the Problem
2. Ordered a New Battery - (Samsung Model From Ebay - I guess it was used or who knows ) >> Did NOT fix the Problem
3. Changed Multiple chargers (Wall Adapters/ Cable from multiple brands which i have at home.. LG, Samsung etc etc) >> Did NOT Fix the Problem
Solution/ What Fixed:
Thanks to redditor.. Who mentioned about CPU power consumption.. And Old Mother board might not be providing enough Power to CPU. (As this tablet is Old.. It was just an Hobby to make it work and Did not want to spend more money on MotherBoard)
By this time I was on Marshmallow Linage OS Rom.. (As Everything works), Gave Root access to one of the CPU app's and Did this..(See Below) Enabled on Boot to keep the same settings.
Setting the CPU max to 1200MHz and Min to 200 it WORKED! I tried every damn thing before. For some reason... this idea did not strike my brain. So its the Power consumption from CPU.
EDIT 1: after some more testing You can go upto MAX 1600MHz (Your mileage may vary)
Finally Battery drained till zero without shutting down.
LET ME KNOW IF THIS FIXED YOUR TABLET TOO.. If you have the same issue as mine. (I Know many had this issue like mine.. but none had solution) Hope this helps.

My Son's Nexus 10 had served its purpose. But Started to die at Random percent, Mostly above 50%.. So Got a new Tablet for him. But Did not want to throw away this Gem of a Tablet.
After weeks of Trial and Error finally found a solution Thanks to input from a Redditor.
Issue/Problem: Dies at Random % showing battery %0 and Shutdown. But In Recovery with Full Brightness it does not Die for hours.. (as later found out.. Recovery does not need much CPU power)

Hi!
I have the same problem for a while. Could you tell me which CPU app did you use?
I thank you very much for your help.

I used below app (But u can use any CPU app).. But other than those above setting(s).. I DID NOT change anything else. But u need ROOT to make that change.
Good Luck. hopefully it helps you too.

Hey You can go MAX upto 1600.. If that doesn't work for u.. Keep reducing a lil by little.

Unfortunately at the moment I don't solved the problem, even if I set the cpu min to 200 and max to 1200.
I've installed a new ROM, deleted the cache and still the problem persists. I will do other tests trying to recalibrate the battery.

Humm... Anyway @1600 mine died at 30% .. So made it 1500 and past below 18% and Still running. So I guess 1500 is max I can go
Also Before coming this conclusion: I did the fowling
Charge 100%
Delete Batterystats.bin
Run this command from adb "adb shell dumpsys batterystats --reset"
And then Changed the CPU max (Please NOTE , Select "On Boot" to keep the same parameters). Once u change the CPU settings .. Reboot and see .. if its keeping the same settings.
Many thanks. I tried all of the the things you tried and setting the cpu max frequency is the only thing that worked.
I could get away with seeing it to 1600.
Deleting batterystats.bin does nothing https://www.xda-developers.com/goog...-battery-stats-does-not-improve-battery-life/
Now with a new battery, PureNexus Rom and your amazing fix my Nexus 10 is a thing of beauty again.

Streetmart you absolute legend. I'd never thought I'd see the day my Nexus 10 would drain down to zero again. I tried 1600, then 1500, to no avail; then I said screw it I'll just go down to 1200 (with little hope of it working).
It feels so weird to actually have an internet “solution” work. I'm super happy. I didn't want to buy another tablet. I love this one and it worka perfect for what I use it for.
Thank you! :good::highfive:
OMG! thank you for this thread! i was just posting to look for a replacement for my 10... i hope this fixes it BTW.. what's the normal max cpu speed? I REALLY don't want to replace it as the new dropbox 3 device thing really screws me..

I think the normal is 1700MHz. It's what the program showed before I changed it. All the best! Keep us updated.

What a difference... i installed that a few days ago, and i haven't used my N10 much but on standby it's still at 99% usually it would be WAY lower.. i think that program did more than just lower the max cpu a little.. don't care though. the N10 lives on!!
If you still have this issue, I have been updating the kernel and also found some of the power control settings needed tweaked. Disabling "opportunistic sleep" "logging time spent in suspend" and enabling "advanced power controls" seems to do the trick. had an issue where the device would shut off if battery level reached 20%. Haven't had it happen again yet.

I'm currently running at 1600 with this guy modified kernel and wow, besides no more suddenly shutdowns it runs very smoothly, it reminds me the pre-marshmallow age of this tablet.

Where are you finding these control settings to change?
I have replace the battery of my N10 because of low capacity.
Now it charge from 0% to 52% then it goes to 100%. On discharge it goes from 100% to 46% then shutdown and battery shows 0%. Percentage is the same in TWRP.
Since replacement of battery it have aroud 10 charge/discharge cycles without any changes.
Any solution for that?

I have to agree on, that the N10 chipset/cpu/powersupply has degraded somewhat & as the battery voltage gets lower during discharge, it can not supply stable power any longer :crying:
If i reduce the CPU speed from 1700MHz to 1200MHz I get to go down to 20% instead the N10 shutting down abruptly at just 30%
I do have a spare battery in the fridge for later on. Once I open up the N10, I'll see if there is a capacitor or two, that could replaced in the power supply area to possibly fix the issue.
Note:
1. On second full charge since lowering the CPU to 1200MHz the battery got down to 14% & I have decided to charge it instead of letting it die at some point at a lower percentage
2. I should have mentioned earlier, that I still use the original N10 battery & plan to replace the original battery with a new aftermarket battery later on if I need to.
3. I use the N10 in an air-conditioned room for no longer, than half an hour at a time only browsing & reading articles with a short 10min video from YouTube.
4. Before lowering the CPU clock from 1700MHz to 1200MHz, the tablet consistently has shut down abruptly, at 27-30% battery level to my dismay.
5. Tried complete battery drain / cache reset to 0% in Recovery mode & then fully charging it while shut down 3 times without success.
6. So far lowering the CPU clock has made a difference & for prof now I am evaluating the N10 battery capacity with AccuBattery.
7. I charge my devices at around 20-25% or higher up to 80% to prolong battery life using apk's to stop charging or alert me.
I have switched to the UNOFFICIAL Resurrection Remix for Nexus 10 (ResurrectionRemix-M-v5.7.4-20161208-manta) MM ROM after rooting my N10 (Danke schön Corinna ) & had to update the baked in Kernel Adiutor.
Installing from APKMirror the "Kernel Adiutor (ROOT) 0.9.73 beta (Android 4.0.3+)" has allowed me to lower CPU MAX Frequency and have it stick after BOOT!

I don´t think so. The capacity of new battery looks really good. I use the N10 as wall-mounted control tablet for my home. With activated DT2W, full brightness, showing cams on motion, controlling home and audio over the day, my new battery runs about 28 hours before it stops. With old battery it was around 15-18 hours from full to off. My workaround: Reading battery with tasker and starts charging at 50%
I think the china batterys have different voltages than samsung batterys and N10 can´t work with this.

Hey,
That sounds very interesting. I may find out about that, when I replace the original N10 battery to my replacement battery from China.
I forgot to mention in my post earlier, that I am still using the original N10 battery. The original N10 battery keeps crashing at 30% unless I lower the CPU clock to 1200MHz.
After the first charge at (1200MHz max CPU) I got the N10 down to 20%+ before crashing to shut down & after the second charge I got it down to 14% at the same 1200MHz without crashing to shut down & just recharged it. Mind you I was just surfing the net & watching YouTube. I am also using AccuBattery to estimate the battery capacity atm. (Oh & don't install Battery Charge Limiter, because it boot-loops the N10 after install!)
DT2W sounds awesome. Which ROM are you using on your N10 to get DT2W, if you don't mind me asking?

Sometimes it shuts down at 20% and other times it won't. I'm almost pretty sure it doesn't have anything to do with advanced power settings or any kind of internal power settings with the kernel. There are no thermal configurations on this device and they don't add any drivers for it or support for it until much later versions. Heat seems to play a role especially down here Florida when outside. So far in my experience it's most likely to shut down at 20% if it's too hot and not likely to do so if it's been idle for a bit or not plugged in.
