Don't bother with that battery charger hack, it's not going to do anything but waste your time...

I just installed SetCPU on my phone just for fun and have found that it recognizes a few lower clock cycles...I added a profile to lower the CPU when the screen is off otherwise at 1024-245 On Demand and I'm still plugging away at 20% battery when I would normaly be on the charger by now...could be a fluke, but so far so good...I'll keep this for a few days to see how it does.
[myTouch 4G General] bbman911:
oh, one other note, my battery life has continued to improve with every charge...the first few days I couldn't get through a full day and now I have battrey to spare...just had to get it conditioned with a few charges I guess.
[myTouch 4G General] PolishDude:
I let the phone completely die last night and then charged it and at midnight I unplugged it. At 8:30 this morning when I left for work it was at 94% which was great but from 8:30 until now it has dropped to 83% and ive had one 3 min phone call and deleted some text messages, no browsing web, no listening to music, nothing. It seems like the phone will go through the 100-95% slowly but after that its in a marathon to get to 0%
[myTouch 4G General] HeavyComponent:
I don't know how you guys are getting so many hours daily on heavy use. I get 7-8 hours on heavy texting, some web browsing and about an hour plus on the phone almost every night. 9 hours would stretch it and it would be on 10%.

I have my brightness all the way down and all the way down is just 11. Screen times out in 2 minutes and I have power saving on. I did the battery thing 3 times where I would let it go down to less then 14% or so then charge it fully without taking it off charge. Hopefully it improves as days go by, I'm just tired of carrying my charger to work.

[myTouch 4G General] PolishDude:
Down to 69% now at 11:15, have made no phone calls or texts since then, have just downloaded opera mobile but havent even played with it...lol this is riduculous
[myTouch 4G General] floepie:
I can recommend that you guys take a look at what might be pinging the CPU. Watchdog (Lite) is great for this task. You can have it alert you when an app exceeds a preset threshold for CPU usage. Some apps just go rogue on you like Palin from time to time.

I've also noticed that there's wide variability in terms of how apps go into either idle or background states. Some apps will go into idle only if you hit the back key to go back to the home screen and will enter a background state (more active) if you hit the home instead. I've also noticed that the free, ad-supported apps require more CPU time. That's right. Hitting Google's ad servers, at least for some apps, and scrolling those ads, requires more CPU time than other apps, which do the same. I don't know whether to fault the devs in this case when coding for the ad retrievals or not. Just some things to consider.
[myTouch 4G General] signal15:
I just got mine. I came from a Blackberry 8900 and an old 2g iPhone. Battery life on both of those was significantly better. I could talk for 8 hours a day on the BB and it would last until midnight-1am or so. The iPhone would only last until 10pm.

Using the MT4G, my battery life is REALLY bad compared to these other two devices. I can get about 5.5 hours of continuous talk time, tested yesterday on a conference call for work. But even with only calling for about an hour and some basic email checking, I can't go past 6pm without putting the phone on the charger.

Wifi is off, screen at 50%. Someone please make a big fat 2800mah battery for this thing. I use this thing for work, and I make over 4000 mins a month of phone calls. It's really annoying to have to plug it in whenever I have the chance.
[myTouch 4G General] Lockeskidney:
im getting roughly about 15-17 hours and im using it (camera, blogging, facebook uploading)

[myTouch 4G General] blitz911:
Heavy usage, I'll get around there, 7-8 hours...regular usage gets me around 20 hours..I'm using setcpu w/ profiles..
[myTouch 4G General] dinan:
did you have similar battery problems with your old phone while at work?

i notice my nexus 1's battery is significantly worse when i'm at work since getting a signal is a bit spotty (35th floor) so it keeps searching around. when i'm at home the battery lasts literally twice as long while idle.
[myTouch 4G General] HeavyComponent:
Yes definitely right about that. I have better battery usage when I'm off work. My department at work is in the basement. So the signal switches on and off the whole time I'm there.

I think I only brought my G2 into work a couple times so cant really comment on that but in the 3 months ive owned the vibrant, if i used the phone a lot during the day....i mean play games, texts, web, etc..id leave with percentage in the 50s, normally in the 70s, at 4 today i was in the 30s with the mytouch with barely doing anything, since i want it to last until the night i just threw it on the charger. it shows I have full signal (4th floor by window)
[myTouch 4G General] elsif1:
My wife just got an mt4g (I have a nexus one). I've noticed that her battery life seems to be just over half what mine is, and I actually use mine more!

When I looked at her Battery Usage display, Android OS was near the top with almost 2h CPU time after being unplugged for 6h. For comparison, on my nexus one, CPU time for Android OS is 4m13s after almost 8h.

Any good way to break that number down more and find out the source of this crazy battery usage?
[myTouch 4G General] agentaaron:
WiFi off from 8am till 6pm...then on when im at home

Background data on

default weather sync off

stocks off

Beautiful widget set to refresh weather every 15 min

google set to sync on mail, contacts, and calendar

brightness at ~30%

I unplug every morning about 7:00am...maybe 30-40 min worth of calls, 20-30 sms messages, 60-70 emails (mostly work related), very light web browsing, check facebook maybe twice a day, refresh twitter usually once or twice a day, 1-2 hours of mp3 playing while I do my morning reports...and i usually try and get a level of Angry Birds knocked out while waiting for my wife to get out for lunch...This is typical usage for me.

I usually have 20-25% battery left when I go to bed between 11:00pm and Midnight...so I guess you could say that my battery is pretty decent.

***This last weekend we went to a friends house on Saturday morning...stayed for a party and did not get home till about 1:00pm on Sunday. My wifes Vibrant had died out about 11:00pm Saturday night, I was still at 16% when we got home the next day (Everyone knowing that I was "the phone guy"...my phone was passed around and played with quite a bit)***
[myTouch 4G General] OneBadLT123:
Right now I am going on 18 hours on average use and am finally down to 20%. I do charge cycles. Full charge to dead, screen set at 20% brightness, when I sleep I turn data off. Been getting 18 to 20 each charge with average use
[myTouch 4G General] PolishDude:
such a large discrepancy between devices, mine is still pretty pathetic, im down to 21 percent at 11pm and i already recharged to about 68% once after it got down to 30% around 5

also noticed my gfs on the other hand now is doing great, hers was just as bad as mine yesterday, today she was at 51% when she got back from work, i was in the high 50s, an hr later, she was at 49%, i was in the mid 40s
[myTouch 4G General] pack:
that sucks, it might just be your battery in general... you can go into a tmo store and theyll trade your battery out with one from a new mt box
[myTouch 4G General] signal15:
I've been running the battery completely dead before charging it fully, and it seems to be improving the battery life. Today, I was on it quite a bit, and I didn't have to plug in until 10pm or so. Still not as good as my old iPhone 2g, and not even close to the BB. But much better.
[myTouch 4G General] PolishDude:
I let my battery die again yesterday, from the time i took it off the charger 8:30am to 10:30am it showed it as "fully charged", in the last 45 min I lost 12%, im going to exchange my battery
[myTouch 4G General] markjnj:
so far my battery usage goes as follows for the day:

off the charger - 5:15AM

on the internet, checking email for about 45 mins

listened to music for about 1hr

played w/the phone on and off I'd say about 20 mins

uploaded a 27mb video to Youtube

wifi and sync on the whole time.

last check - 1:25PM 56% battery left

So far I'm getting about 8 or so hours at the half way mark w/light to moderate usage.

anything below 8 hours a day I would factor in, new toy excess usage, and playing w/everything. I got mine Saturday and was getting 8 hours for the day, but I felt like I was playing w/it more than i did w/my motorola cliq xt. So we'll see...
[myTouch 4G General] salazarn54:
Just wanna throw my 2 cents in. as of right now. im at 13 hours 10 minutes and i have 54% battery left. i consider myself a pretty heavy user. txt and checking facebook all day. email. and about an hour of angry birds. lol. i dont have wifi or gps on, and dont really use bluetooth. my phone stays on H all the time. never switch to Edge. i think thats pretty good battey life. i think the big reason for this is a app called superpower. you can find it in the market and was developed by a xda member. i would look into guys. it makes a big diffrence
[myTouch 4G General] floepie:
You guys know that having your wifi radio off in favor of using UMTS (3g/4g radio) will actually use *more* power? If you leave your data connection on and you are near wifi for a good part of the day, you should turn your wifi radio on. By having it on and connected, your UMTS radio shuts off by itself, and that radio will use more power than your wifi radio will use.
[myTouch 4G General] markjnj:
I usually have wifi on while at work and at home.

wifi off and gps on when I'm out and about.
[myTouch 4G General] deskhack:
I am having a similar issue with 'Android OS' under battery use. If this item is showing 30-50% then my battery is dead in several hours. If it is showing <5% then my battery is +80% after a full day of being unplugged with minimal use.

Update: using Watchdog, the culprit appears to be the 'suspend' process, currently using 40-50% cpu when the screen is off.
[myTouch 4G General] werk:
See my post here, perhaps you have the same problem as me:

http://xdaforums.com/showthread.php?t=839935

Download an app that can monitor system processes (I used Watchdog). Enable it and set it to realtime CPU. If your init process is eating serious CPU, enable USB debugging and it should stop the init process bug.

Additionally, I have found the suspend process eating CPU as well when the phone is locked/screen off. A reboot fixes this for a while...it eventually comes back from time to time. It doesn't eat as much battery as the init bug I've experienced, so I'm less concerned.

Very annoying as both of these issues are Android/Sense issues and not a problem with this phone in particular.
[myTouch 4G General] nmw407:
So far, I've had this phone for about a week. I usually have WIFI on, GPS off, auto-brightness on, GSM/WCDMA on auto, and the phone has been lasting roughly 12-14 hrs a day. That's including playing pandora for at least 2 hrs each day, plus a few tv.com episodes.

It could be better I'm sure but right now I'm just happy it lasts that long, especially after coming off the G1 and it's abysmal battery.
[myTouch 4G General] gr8one698:
I've been getting roughly 12-13 hours out of my battery. That's with moderate internet and messaging. Wifi always on. ATK pro set to autokill every hour. So far, it's not the best but much better than the EVO I returned. :)
[myTouch 4G General] deskhack:
Tried this, init process is not the issue, just the suspend process. I agree restarting temporarily fixes it but then the issue comes back for no apparent reason. I am still concerned because it's the difference between having +80% battery at the end of the day and ~20% with the same usage.
[myTouch 4G General] werk:
Yep, it really sucks. There are several other posts in other forums for other HTC devices with people with the same problem. I just saw an update to this post:

http://androidforums.com/evo-4g-support-troubleshooting/161412-suspend-process.html

where someone recommended an app called "cache cleaner" that appears to be helping him with the suspend process issue. I'm going to give it a try.
[myTouch 4G General] theinternot:
Wifi on this phone seems to just kill the battery. I was having my battery drain on me overnight... as in 100% to Off in about 8 hours. Started manually managing my wifi and my phone is lasting over 24 hours.

I came from a Samsung Captivate which was a battery eating machine... the recommendation for that was to leave ON wifi cuz it consumed less juice than trying to stay connected to 3g...

I don't know, guess every phone is different.
[myTouch 4G General] SugarMouth:
Go into accounts/sync menu. Take a close look at what is syncing and how often. I improved my battery dramatically by changing those settings or removing items I don't need synced.
[myTouch 4G General] halfcalf:
my battery life was terrible until i did this

http://xdaforums.com/showthread.php?t=839935

i actually did it before i saw the post and noticed a huge improvement in my battery life but didnt know that that was what did it until i stumbled on that thread
[myTouch 4G General] werk:
I didn't realize cache cleaner required root, so I didn't use it.

However, I did go through my apps and remove as many as I could (those that I don't really use) that were listed as having "prevent phone from sleeping" permissions. Since then, I haven't had the suspend process go loco again, and last night when I went to sleep, I had almost 50% battery left, whereas usually I'd be down to 10-15%! I'm hoping some app I had installed was the culprit. I didn't really note what I uninstalled. Facebook was the only one I really recall. I've had some pretty heavy usage today, flash video for a while this morning, lots of surfing/email, a call or 2, and a 15 minute logmein session and battery is still at 87%. Things are looking better on the battery front for me now!

EDIT: Chrome to Phone was another app I uninstalled, it doesn't work with my Google Apps account anyways.
[myTouch 4G General] Biggizzel:
The first ten percent drag by, then look out zero will be here before you know it. My battery last me about an 8 hour work shift, the only problem is I work 10-12 hour days!!! :( My car charger is my best friend!!!:p
[myTouch 4G General] royhobbs:
I haven't purchased a new phone in 3 years, coming from a T-Mobile Wing, so this is all fairly new to me. I expected the battery to last me through the day and so far it appears to be pretty lousy. I have tried shutting down screen brightness, turning off data and wi-fi connections, etc. However, the battery completely died on me tonight by like 8-9 pm. That means it was at 30% by the time I left work, which to me seems pathetic.

I have noticed Android OS under Battery usage as a fairly large chunk every day. Wondering if there are any other "Starters guides to android battery use". I'm also wondering why I have to go through so much crap just to get decent battery life, hardly seems reasonable to me. Any other tips are greatly appreciated, I really like having a new phone, this phone is pretty awesome, but if it can't last me through the day...

Ok, so I also let the phone die completely, as I have several times now, and then I charged it all the way. I also unplugged it once it was fully charged (is this recommended?) Here are my results of my last charge:

Currently at 7% Battery charge.

16h 45m since unplugged.

Display - 30% - Time on 1h 12m

Android OS - 26% - CPU total 1h 55m

Maps - 15% - CPU total - 10m 13s - GPS - 24m 31s

Cell standby - 9%

Phone idle - 8%

Android system - 4%

Wi-Fi - 3%

Voice calls - 3%

com.htc.launcher - 2%

Any thoughts on this? Does this seem normal to you? I will say this is the lowest I've seen Android OS, usually it's a lot higher. I appreciate the link regarding the USB Debug mode and Watchdog. I will try both of those this weekend. I am wondering if those of you who get really good battery life are using those techniques or if you got a better phone/battery from the beginning and didn't have to use them?

Thanks.

I'll post any other progress.

Hey guys... I have had my phone for about two weeks and all had been well, but last night, while I was asleep, my phone didnt make it through the night while on idle... Which is definitely unusual.. I went to bed and had 88 percent battery...

And..

..When I woke up in the morning, the phone was completely dead.. So when I got to work I put the phone to charge.. And after a full charge, my battery seems to be dying significantly faster than usual...

So..

I checked watchdog and cant seem to find any rogue apps in the background... Although I did notice the phone's idle cpu usage has been upwards of 51 percent (i've seen it as high as 74 percent)... This of course cant be normal... and I cant seem to figure this out..

I did a search on the forum and was unable to find a solution... Usb Debugging has been checked off and I only have gmail and facebook syncing every couple hours... So overall nothing has changed except the phone idle cpu usage..

Has anyone else faced this issue? I could really use some advice on how to go about resolving this issue..

Thanks
[myTouch 4G General] gotti109:
Same with me, my idle % is usually 73% and up when im not using it...this morning i used my phone from830am till about 940, text, phone calls and slight internet usage(5mins) that left me with about 87 battery... now that i checked my phone at 130pm, my battery drained down to 49% and i didnt even touch my phone, this sucks, but i still love this phone!!!!
[myTouch 4G General] borodin1:
I tell you all one thing... SetCPU profiles do wonders. I have mine @1497/768/on demand/screen on, 368/245/powersave/screen off and 768/245/on demand/battery <20%.

This set-up lasts me about 14 hours of fairly heavy use (gmail/facebook/twitter sync , auto-brightness, live wallpapers, browser, gtalk, some streaming)

This morning I took my phone off the charger at 6:30 am. It is almost 1pm now and I'm still at 78%.

5 hours 58 minutes since unplugged:

Cell standby - 57% (Time without signal - 55%, I'm in and out of the basement all the time)

Phone idle - 23%

Android system - 12%

Everything else is insignificant.

Ridonculous - best way to conserve battery, "Shut them all down"

Update for today's battery experience:

(Rant first, stats after)

Why have a "smartphone" or "superphone" if I can't even use it?

Turn off data, dim the screen, turn off sync, don't update anything all day and maybe, just maybe it will last you. But don't dare make any phone calls, that's for phones.

Currently at 9% Battery charge. It was warning me an hour before I left work that it was low.

8h 36m since unplugged.

Android OS - 41% - CPU total 2h 23m

Display - 33% - Time on 1h 11m

Cell standby - 6%

Phone idle - 5%

Android system - 4%

Voice calls - 4%

Watchdog Lite - 3%

com.htc.launcher - 2%

Plugin sample - 2%

I have had about 2-3 phone calls today, probably 30 text messages. That's pretty much it. Nothing else. BTW, I don't even have Facebook on this phone yet, although it doesn't matter, I haven't synced a single thing since I took it off the charger.

Background data is off

Wifi off

Sync is off

GPS is off

Screen brightness was almost at the bottom all day, I finally turned it up.

I installed watchdog and it has finally started reporting the suspend process at 30-50% since I enabled monitoring Phone processes. Most definitely seems to be the culprit.

I will probably try USB Debug tomorrow, but I'm considering returning this phone while I still can. I don't think I should have to go through this crap to get a normal days use out of my phone.

Thanks.

I'll post any other progress.

Try setting some profiles for screen off and put cpu down to 368 etc. I have some profiles setup and this is what I'm getting. Keep in mind most of it is in standby but this is good for me as I don't use my phone all that much.

Holy low display percentage! I posted a question about my percentage being around low 70s. I guess I might use my phone a bit more than you.
[myTouch 4G General] bobsbbq:
Yes you are right but with the stock settings and ROM I was not able to get this kind of battery even in standby.

Even now I'm at 1 day 13 hrs and 47 min since unplugged and I have 69 % battery left. All I can say is this is awesome battery life with setcpu profiles. I also disabled sync for stocks and T-mobile as they eat the battery. My gmail sync is every 30 min, weather and news every 6 hours.

[myTouch 4G General] Lakeshow423:
Let me share my experience with my battery. To make a long story short, my MT4G would not root for the life of me. I decided to swap it for a new one at T-MO on Thursday. I got my new phone @ 11:30am with about 40% battery left. I rushed home and rooted the phone. Everything went to plan. I was messing with the phone and trying out a few things...it finally went dead at 1:30PM. I charged the phone for about an hour till full to start the condition of the battery! I pulled it off the charger at 2:30PM.

I am new to the android world and my main goal was to get good battery life, customization, overclocking, freedom to mod the crap out of a phone :D . A member in here was helping me take out the bloatware the phone came with and it really helped! Go to root explorer system/apps and you will find the .apk files the phnone came with. You want to hit the R/w and multiselect! Then move the files into the SD card, just make a seperate folder. Here is what I took out.

*amazon

*AppPack

*Asphalt5

*Monopoly_Classic

*websharing

*qik

*rockband

*SelfHelp (This is the dreaded MyAccount! This eats up alot of battery)

*Stocks

*T-Mo TV

*My touch demo

I added setCPU and put the settings at 368/368 when screen is off and basically running it 1024/245 in the other profiles. I added ATK and did a ignore list with what I want on and set the kill apps every 30mins.

I was messing around with the phone like 80% of the time from 2:30PM till 1:00AM. I had WiFi on all the time and Brightness was set around 40%! I was off that day so I wanted to know how this process would turn out. I was installing battery Zips, removing bloatware, backing up, surfing, talking, texting! Heavy Use! Heres the chronological order:

2:30PM - 1:00AM ( 45% Battery Left! WOW! ) Heavy use on the phone! Installing stuff, moving stuff around, talking...ect. Turned off WiFi before sleeping.

8:00AM - Woke up battery was at 43%! only 2% movement! I guess the process was working!

8:00AM - 1:00 PM Battery died after heavy use! Almost got 24 hours on a single charge while rooting the phone, flashing, talking...ect!

I just got done condtioning the battery for the 3rd time and heres a screen shot of it. Wifi was on and did some surfing, a couple of texts and a couple of phone calls! The screen says it was off the charge 1 hour and something ago, its on the upper left! Look...still at 100%.

I have Wifi On, Sync Off, Brightness set to 40%, and turned all the updates on the apps to every 4 hours and if I need to check my email, I would just update manually! I am on Stock Rom and scoring 1890 in quadrant stock! I guess the bloatware holds this phone down. I was scoring 1500-1600 on my old MT4G!

Sorry this post was so long but I just wanted to share what was working for me :D
