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.
So I read this fuzemobility.com article about battery life and thought I'd write a super long comment with sweet hyperlinks but it turned out to be too long for their blog configuration. So my XDA friends, here it is. I invite you to contribute any tips and insight you may have to the handful of gems I came up with about gems other people came up with:
WMLongLife by Chainfire, the venerable codemaster known most for wmwifirouter (even though his other work is awesomely impressive), drops you down from H*/3G to EDGE when your screen shuts off for a minute. It will also kill the data connection if inactive for a minute. When you turn the screen back on, it stays on edge, but if you start an app from a 3G whitelist you make, like including Opera and SiriusWM5 but not FlexMail, that app will kick it back into 3G. Switching from edge to 3G takes roughly six seconds he says but probably worth it if you like to save yourself battery (and your gonads from radiation).
Thread
Lumos by nik3r is a great replacement to HTC's included backlight adjusting system. It uses the light meter and you can specify how dim you're willing to go in dark conditions and how bright you have to have it in sunlight. You can tweak every point in between if you want, define what conditions you believe to be bright (and warranting full backlight juice) and dark (running low power). Very low cpu usage, low memory, no battery drain when not using the phone, no cpu involved with fluttering backlight levels, delightful gui frontend, fun to configure. Requires phone with a light meter like the Raphael and Diamond.
Thread
IMAP-Idle or push activesync or instant messaging or PocketPuTTy or PocketIRC or PornTube or anything that keeps the data connection open, even with very little throughput going on, drains substantially harder than having no data connection (just phone, SMS) so use that knowing you're sacrificing battery life (which I do). I'm not sure about this but if you like to use AIM and have an unlimited text messanging plan, using an sms-based IM client like OZ Messenger/Mobile IM may use less juice than something like Agile or IM+ which keeps the connection alive. What I am right about is insisting that you use Outlook Email Scheduler to specify Pocket Outlook synchronizing frequencies over peak and off-peak hours, brilliant program (also does imap idle!!). So with this, in addition to "push" mail which now supports gmail (it's actually called IMAP-idle with non-Exchange mail servers), you can set your phone to cycle pocket outlook synching, say, every five minutes during the day and every half hour after 10pm, whatever you want.
Thread, website.
This one is more for convenience than it is a miracle battery saver, but Touch InCall Screen Tweak by StevePritchard shuts your screen off when you take a call and put the thing to your head and, using the light and g-sensor, when you pull it away as if to dial in your calling card it lights it back up and when you put it back to your head, it dims it. Very handy. The NoSleepRaphael killer.
Thread.
I definitely do not recommend trying this if you are afraid of danger or bricking your phone but here are two links for you crazy underclockers. I can't tell so far if it does in fact successfully throttle my processor, I can't tell if I was able to get the speed back up either by setting it back or by uninstalling, I just don't know but here it is. Couldn't find much feedback so if any of you know how to test battery drain and also don't care about warranty compliance, maybe post results in this thread which I have no doubt will blow up into huge popularity . You must have a Qualcomm MSM7XXX(A)-based processor, so google first to double check:
nueDynamicClock, nueClockControl
Raphael/Touch Pro/Fuze users: Make sure you got the right radio with the right rilphone.dll properly installed. If you're AT&T grab 1.12.25.19, not 1.14.25.05 (I've only seen mixed reviews and I myself was not breathtaken it), and then Chainfire and P1Tater's 1.12.25.19/rilphone.dll combo cab. If you're not AT&T, I believe you want to stick to 1.11.25.01 (and grab the right rilphone cab accordingly). If you're fully Olipro-unlocked, you probably know enough about non-Raphael radios and don't need my advice.
Raph radios, Chainfire/P1Tater raph rilphones.
Rhodium Manila is badass, I know, and I have a lot of respect and appreciation for xboxmod and his posse (I'm really in awe) but don't use Rhodium Manila if you want to save battery life (or ram or storage or cpu) more than you want to be dazzled by TP2TF3D. Use pjc's ripped oldschool HTC Home (vga) with TodayAgenda underneath. Maybe SPB Mobile Shell's better than regular Manila, it's probably better than Rhodium Manila (in terms of battery at least) unless you're spinning the 3D stuff nonstop. I don't know about WM6.5's efficiency. Just flashed it. If you know, post. SPB Mobile Shell's trialware btw.
PJC's HTC Home thread, TodayAgenda's site, SPB's site.
If you try to do your own power tests to contribute your scientific studies to your local Ultimate Radio Thread, keep in mind that in lower signal areas your phone must crank out bigger radio waves to reach the tower. So you must be careful to keep everything constant except the variable, the radio, including the time-range during the day you do battery and bandwidth tests (including weekdays versus weekends when switching from one to the other) as in dense areas, capacity gets maxed out with carriers who don't have enough infrastructure to handle the loads. I get this all the time even in Manhattan where you'd think AT&T would get their poop together.
You could cruise through the Accessories forum of your phone (here's the Raphael's) to hunt down an extended life battery but those tend not to be cheap, they make your phone thicker, you have to recalibrate your phone's mechanism to measure battery power and the initial charging training is a ***** and there's a chance you'll get ripped off so consider just buying an extra OEM battery and maybe an extra charger for your office. They fit well in that little secret pocket of your jeans, unless you already use it for a zippo lighter.
Contrary to popular belief, there is no memory effect issue with lithium ion batteries. Don't do full discharges with this intent. Don't do that. Your battery's longevity diminishes over usage, including deliberate discharges. Best bet, for a phone you rely on, is to charge whenever you can charge. Yes a battery's longevity diminishes faster over time if you store it with a full charge (verus 50%) extendedly, but hey, you need that sucker ready to go so use it and buy another one eventually. Temperature and resistance also accelerates decline meaning if you use an equivilant amount of milliamp hours over a week with your phone on standby versus four hours using GPS or wifi, and you do this a lot, it takes a heavier toll on your battery. If you have two batteries and tether or GPS or wifi a lot and then are in situations where you don't do that, consider designating with a sharpie one battery for brutal use and the other for light use. If you're draining heavily over long periods of time while charging your phone, that eats away at your battery's long-term longevity the same as if you used it and then charged it. Actually probably a little more because charging your battery heats it up even hotter than tethering all your pr0n which hurts. Two batteries. Drop $45 at your local dealer or search on froogle to save a few bucks.
According to IRC, there is no idle drain difference between regular 3G and HSDPA (but there is between either of those and EDGE). It all comes down to throughput, not the protocol; however, if you're in a rural area where there is only EDGE, you probably want to shut off 3G as, I'm told, your phone eats up considerable juice by trying to search for a 3G tower. Note that charging on USB theoretically gives you 500mA tops (more like 400 at best) whereas your charger is 1A (at least for the TP). If your phone gets hotter than 43 degrees celsius (use BatteryStatus or this Battery.zip which is a ppc exe to monitor temperature and drain) it will, based on my studies, charge slower, and not at all at 47. ABCPowermeter, by the way, does not work on Touch Pros and I'm guessing on its cousins either.
That's it I'm done.

Nice roundup, well done! So, not much left to add. Still, this is my contribution:
Like Touch InCall Screen, cleanRAM isn't a miracle battery saver. But scheduling it and not letting it wake up your device to clean your RAM, could also increase battery life if it kills zombie battery draining processes. And managing your memory this way also keeps you from soft resetting, saving battery.
In Advanced Config, enable all the Power Management settings. And I have Network - Turn off Wi-Fi if no activity: set to Yes; Network - Wi-Fi auto off timeout: set to 1m; and in Menu - More settings - Connections, enable Disconnect after: set to 45s. I don't know how much impact the G-sensor and Light sensor polling intervals have on the battery. But it probably won't hurt if you increase them to a level that works for you.
Apart from all the nice sensor based (un)locking and launching features this lightweight application offers, I have TouchLockPro set to suspend my Diamond again after 5s, after it is woken up without unlocking it. Enough time for me to unlock it. Or just check the time or check whatever application running in the foreground at the moment of suspend. Because TLP has no foreground window like S2U2 or PocketShield.
Using a locking mechanism is already a battery saver by design, by the way. As it prevents unwanted key and touch screen actions that could possibly have an effect on your battery life.
I'm also used to suspend my device myself whenever I think I won't use it for some time. As long as it doesn't take too much time. So I've set the G-Sensor options in TouchLockPro to lock and suspend when I place it face down on any surface. And it also locks and suspends on top down. So I just have to put my Diamond upside down in my pocket, as I always do, and have it locked and suspended.
When it lies face up, I don't need to pick it up and rotate it in any way. I just keep the WinMo start button pressed for about 1s, because the QuickMenu option Long-press win logo is set to suspend.
Just in case I forget to suspend it myself I have the WinMo Settings - System - Power - Advanced options set to the lowest possible settings. Backlight off after 10s and Device off after 40s on battery power. And I have Backlight - Auto adjust backlight disabled for Lumos, of course. There's just one problem. Sometimes, somehow, Backlight - Auto adjust backlight is enabled and both Advanced - Turn off backlight and device are disabled. Without me knowing. I've noticed it a few times after a soft reset, but I can't reproduce it at will. Maybe I'll look for a way to force my power settings after soft reset.

acbTaskMan (which includes CPU and power graphing ability of acbPowerMeter) does have a version compatible with the newer HTC devices. I'm using 1.4.2 on my HTC Diamond.
Another Way of Switchiing Phone Band
Another way to switch phone band, based on MortScript and Vijay555's VJOKButt. Very lite but it works, check here:
http://forum.xda-developers.com/showpost.php?p=3726097&postcount=11171
Be careful with any automatic band switches as if it does it during a phone call it WILL drop the call. Also keep in mind that if you force things to EDGE you cannot do voice and data at the same time.
In my experience, there is zero power usage difference in EDGE and 3G/HSPA except when transferring data. If my phone is running its normal compliment of programs (GPSToday, S2U2 2.02, PhoneAlarm, KaiserNotification, AEButton Plus, GPSGate, CellID (uploads CID to predefined location if changed every 10m), etc, the phone runs <1%/hr battery. If I enable Flexmail, which has two online IMAP mail boxes and about 6 others it syncs every 6 hours, 7-8%/hr on 3G, 3-4% on EDGE. So as the OP mentions, it's data usage/throughput/type but not necessarily just being connected, has to be in use.
As for backlights, personally I can't stand those programs that autoadjust the backlight as it ALWAYS fails in my office where the phone gets in the shadows and then I can't read the screen because it's too dim. But perhaps still useful if you can set how low it can go, as long as it doesn't interfere with PhoneAlarm, which I use to set the backlight for some given profiles (night time, car daytime, etc).
Good post, hope some people learn from it.
Yep...
You're fricken awesome.... Need I say more?
I just thought I should point out that you can see a marked improvement in battery life when using TF3D2 if you go to the internet tab/menu/data settings and disable push pages!
where i tup your .exe ?
in internal folder ?

So, if I understand correctly, the option "disconnect data connection after xx min" will not change the battery consumption ?
I can let my Phone continuously on HSDPA or EDGE with no difference, only when I use the connection.
other question, wich one (EDGE or HSDPA) consume more power when transmitting ?
thanks
Maybe this Battery Guard application could prove handy for battery conservation fanatics
Thanks for this post. I am about to get a Touch Diamond and have heard about poor battery life. This post gives me some confidence that I should be able to tweak my device.

Its a HTC mate & the battery life will always be crap, its the price we pay to be cutting edge i guess
I am trying to compile a large list of tips and tricks that we users can use to extend the life of our small batteries.
List is here:
http://android-simplicity.blogspot.com/2009/08/bag-of-tricks-1-increase-battery-life.html
On-Going Power saving List
1. Under-clock your cpu(for root users only). Download->over clocking widget->set cpu speed to lowest value
2. Turn off GPS
3. Reduce the number of start up apps
4. Restart phone
5. Lower screen brightness
6. Turn off Wi-fi when you are not around any wifi networks
7. Turn off 3G Mobile Data Network - Settings--->Wireless Controls--->Mobile Networks and check the box that says "Use Only 2G Networks.
8. Disable auto Data Sync
9. Download and install "Power Manager"
10. Disable back ground apps - [~JDBDogg]
11. Turn off keyboard backlight (for Dream/G1 only for obvious reasons) with Backlight Off app. Only works on rooted phones. [~Chahk]
12. Turn off any unnecessary noises or vibrations, such as for on-screen keyboard and games. [~AdamPI]
13. Make sure your firmware and apps are up to date, efficiency may be improved. [~AdamPI]
14. Use headphones. [~AdamPI]
15. Turn off Bluetooth. [~AdamPI]
16. [~Yours goes here]
If you have any tricks that you use to get the most time juice out of your phone, please share them to the rest of us. Thanks.
Disable background apps
Turn off keyboard backlight (for Dream/G1 only for obvious reasons) with Backlight Off app. Only works on rooted phones.

nice, one ! didnt think of that~
Lower the time it takes for the screen to time out.
Id also say take off any widgets you may have but i guess that falls underneath the "disable background apps" category
Bluetooth isn't mentioned.
Turn off any unnecessary noises or vibrations, such as for on-screen keyboard and games.
Make sure your firmware and apps are up to date, efficiency may be improved.
I'd guess using headphones is better than the speaker, plus no-one on the bus wants to hear your "music".
Has anyone tested decoding efficiency of video and audio codecs? AAC saves space, but does it use more battery than mp3?
up to 15

Now thats thinking out of the box. Thanks AdamPI
We have now 15 on the list. Lets see how long this can go~
Someone should do a test using all of these tricks and do a comparison, although it will be a very boring phone at this point with everything off.
Don't use a ROM that requires a linux-swap Partition
This causes the phone to die faster because the sd card is constantly being acessed

SD Cards are so cheap these days that you shoudn't worry about damaging them. In a weird way though, this advice does make sense. Swap = more apps are being kept in memory, thus more work being performed by the phone, which translates to higher power consumption.
But then again, following this logic a similar advice would be to not run any apps at all. Or better yet, just shut your phone off! Maybe then it will last a full day on a single charge
Seriously though, if you're worried about damaging your phone, read up on Lithium-Ion/Polymer batteries and how to prolong their lifespan. The main points are:
Don't let them get too hot. Heat damages battery cells and cause them to lose their capacity.
Deep discharge cycles (letting the battery drain before fully charging them) kill these batteries fast. LiIon/LiPolymer batteries like to be "topped off" once the level gets to 60-70% mark.
Discharge cycles can improve state-of-charge estimation, so only perform those when the battery meter goes out of whack and doesn't tell the charge level properly. This doesn't happen often.
They don't suffer from the "memory" and overcharge issues that used to plague batteries using older technologies (NiCad/NiMH), so it's safe to keep the phone plugged in whenever you can.
The "first-time cycle" is a myth left over from Nickel-based batteries. This means you don't need to charge the batter for 8 hours the first time you use it.
Do not use "fast chargers" since their usage can decrease the lifespan of the battery.
Get an app that turns off your data network completely (like WiSyncPlus). Not just "use 2G only" but COMPLETELY. I can go a whole weekend, with normal use, without charging my phone if I need to. (From one Fri 6am to Sun 6pm give or take was my best)
The one I use (WiSyncPlus, there are others I guess) turns off the network automatically when I unplug the charger from my phone. Txt msgs piggy back the cellular network so no issue there, otherwise, if I want to jump on the internet or check the weather, I hit the toggle switch on my Home screen...in ~3secs I'm all set again. Toggle back off when finished.
Best $3 by far I've spent on an app for my G1.
i use APNdroid for that
No one mentioned using a ROM that allows changes to the CPU scaling.
I'm on Cyanogen 4.1.2.1 and I have it scaled from 245 to 527 with the CPU only jumping up to the next clock speed when it needs it.
So, most of the time, my phone is on 245 and it clocks to 383 and then 527 as needed. I had overclock widget set so it showed me the current clock speed. Once I was comfortable with the frequency and load under which it changed speeds, I removed the widget from the desktop.
I use my phone a lot and it lasts a full day easily.
if youre using a hero rom there is an option to completely turn off mobile networks so there is no data connecion at all.
i have to go with
turn the phone off
get a car charger
spare battery or extended one
Hi all!
Currently my battery drains about 3% per hour in sleep mode, I don't know if it is normal or not, but the point is that I don't want it to worse rapidly.
For this reason I am asking you, how often you charge battery, if you wait it is fully discharged or not, etc...
In effect it is because I asked it to my professor about this and he answered that different than the old Ni-Cd battery packs requiring the deepest charge-discharge cycle possible, these new generation Li batteries on contrary need to be charged as much as you can and have a durability inverse proportional to deepness of charging process; this means it is better to charge it every time it is possible without to let it discharging.
Now, share your opinions about that...
He's right! Li-Ion and Li-Polymer batteries are most efficient when charged frequently, with a deep discharge/recharge about once every 3 months to reset the battery condition monitors built into the batteries.
They are best left on a USB charge when near a PC, but of course a long day out with these new devices often means they are pretty run down at the end of the day.
In reality, the battery life, even when frequently discharged will probably outlive the lifespan of the device but I've had a few older ones that have needed a new battery after 3 or 4 years.
3% use per hour in sleep mode isn't bad considering it is maintaining a phone signal all the time- does it regularly poll for emails etc?
Thanks for your reply!
About drain issue I can say I use WMLonglife that should disconnect idle connections after a prefixed time and it seems to work as what I can see when screen is on. I can not confirm its regularity on screen off mode, but I presume so, given its proper behaviour in other mode.
I can add that I have a "flat" connection and every connection is preferrably (in order) Hsdpa, 3g, gprs.
My Leo is equipped with:
1.43 T-Mobile UK ROM, 1.24.xxx radio
Don't know if it is important.
I've seen this probably
3% per hour is bad because it means the batteries full lifetime without turning it on would last close to 1ΒΌ days only. You either are on the limits of cell coverage or more likely your device is going to screenoff instead of sleep. Think what you have tweaked and investigate power states. Also, there might be an app running that requires some functions that are available only during power "wasting" power states and keeps the device in screenoff power state.
Thanks for your contribution... but how can I investigate on its real power state, how can I assure if it is really in sleep mode or has only shut down screen?
Same here. Battery lasts less than a day without much usage. I switched off 3G completely now and am testing how long it lasts now.
There is a HTC location option (in the configuration tab of Sense) which can be switched off. Perhaps it is this thing which eats power? What's it for anyway?
The location option is for determining your current location for services like actual weather conditions. It determines your location by using the GSM base stations and signal strenght.
You could disable this, but above mentioned services will not update automatically anymore.
Might indeed want to check any programs that could have auto-update/sync with internet on. My battery typically drains 7-10% per night with half-hourly sync (weather, twitter, mail, etc) and all other options like location services on. I'm on Vodafone branded 1.43 NLD stock rom.

Click to expand...
Click to collapse
The best way is to download Battlog and check from logs what is happening. It tells you the states and everything. The best thing is if the logging stops during standby. This means it IS sleeping
Hi guys,
If I remember correctly, in the previous WM versions there were options to change the speed of the CPU and that way to save the power and reduce battery consumption?
I am preparing for long, few days GPS assisted hikings and would like to minize the power comsuption of my HTC HD2.
Maybe there good apps for that too?
Thanks.
It already does that automatically.
Consumption of a GPS app like GPS Tuner with screen off is already very low, giving about 8hrs battery life (if you don't do anything else, of course).
