I've had my HTC Touch on CDMA/Bell Canada for about half a year now. I love the phone but the battery life just sucks. I can't get through a full day without having to plug in. Where I work and where I live the CDMA signal is weak. My phone is constantly flipping back and forth between X1 and EVDO and voice calls are not very reliable.
I know things like Push mail, GPS...and other data agressive applications will drain the battery, however even when I turn everything off except for the phone itself I can't get through a fully day.
I suspect my phone is constantly busy trying to maintain a connection to the cell network. Does anyone have any tips on how I could help get better battery life?

It is very hard to provide you with any help when we really don't know what you have installed and running on your phone. Some plugins can drain your battery while they are running - EG - WeatherPanel - Try not to let this program keep running if you have it installed - especially with animated weather icons. Reduce the brightness of your display screen if you can manage that. Make sure that your display is shutting off as well. Keeping the display on will surely drain your battery. Set it to shut off after so many seconds of inactivity. Take a look at your task manager to make sure that you don't have many programs running in the background - and set your task manager to actualy close programs when you tap on the x as it is default setting to just minimize your apps and not close them. If they are all running in the backgroung, you will surely see battery drain.
With a bare bones configuration my battery would last around 10 hours before I had to plug in. All I had running was basically my phone and some light web surfing.
I've since loaded up my phone with a apps/plug-ins and my battery last about 5 hours now sometimes less. I am running some apps which do things in the background:
-Weather Panel, no animated graphics (Auto update every 6 hours)
-HTC HUB (Auto update every 6 hours)
-Push Email (Zimbra mail, looks like Exchange)
-Pull Email (Gmail) every 30 minutes
Even if I can get all these applications to be much less power hungry, I'll get at most 10 hours. I'm hoping to get multiple days of battery life, not just hours.
While on holiday I turned off the phone, went into Flight mode for a week, but still used GPS on occassion. My batteries then lasted days!
Thanks for your suggestions about those apps.
I can almost go more than half a day, which is enough to get me from my house, to work (or wherever I go), and back home. I'm thinking I should get a spare charger for my office though.
But I have running:
FlexMail, with 2 IMAP accounts, and Live account
Palringo or Live Messenger (depends which ROM I'm using !)
Some Opera browsing
Occasional GPS
Some MP3's
And the obvious phone calls
Ohh, and when I get bored, some Kevtris!
I leave work at 4pm, and when I arive at work the following day at 7am, I'm usually at 20% battery life, and that's with it being plugged in via usb for at least 3-5 hours during the evening. Barebones flash, with SPB Mobile Shell 2.0, and that's about it. It's a bummer, having to stay close to a usb port or wall outlet.
I did notice, my normal power consumption is 150-250mAH, however when I plug in to usb, it jumps to 400-500mAH, sometimes higher. That is with activesync or without, doesn't seem to make a difference.
Well, I don't know about Zimbra, but I know the SEVEN push service absolutely *destroyed* my battery life. I just set my phone to check my Gmail every 5 min, and it's good enough for me, with much better battery life.
That said, your problem is your location. Your phone will burn a lot of juice if you work in a basement or dead zone trying to find towers. There's not really anything you can do about it, other than turn off the phone radio when you know you're going to be out of range, but of course, that defeats the purpose of having a cell phone.
Get a new job, get a 2nd battery, or plug it in at work. Smart phones don't have great battery life to begin with, and if you are getting a weak signal, you are just out of luck.
[EDIT]
Or, you can try one of those Sprint base stations. You may not be able to set one up at work, but you can at least do it at home. Should help some.
I got an extended battery (Seidio 2000 mAh) and my phone lasts for more than 24 hours now, probably 2 days if i let it go without a charge long enough.
Like right now I have had a bunch of phone calls, done a bunch of texting, played some kevtris and my phone has a lot of stuff installed on it. It's been off the charger since 9:30AM and its 4:40PM now and the battery is at 81%.
Before I got the extended battery my phone would probably be at less than 50% at this point in time. The extended battery does make the phone A BIT bulkier, but its really not that big of a difference to me.
Hi
Yesterday arrived my dev phone 1 and I am very hapy with it bu battery level is at 20% at 18:00. Is this normal?. I dont want to switch the band to 2g. I keep gmail synched with direct push but google talk not. anyone with same prpoblem?
Thanks
yeah, the standard battery in the G1 is ****ing terrible
not a lot you can do except buying an extended battery (which is a very good idea! )
The only thing I have found to extend my battery Life has been discussed previously a few times on these boards...
1. Turn off Wifi, when not in use. (Toggle WiFi from the Market is Great)
2. Turn off GPS, when not in use. (Toggle GPS from the Market also great)
3. Turn down the screen brightness.
4. (not sure if this makes a big difference) But sometimes if I do not need my feeds or background running apps throughout the day I will restart my phone, or run through a few applications that are not pulling web cache. This way you dont have auto update feedreaders in the background running. It seems like it works for me, but that could very well be wishful thinking. Also turning of things like Twitroid update etc...
Hope that helps.

i do #4 as well, it seems to help, since i have root i just go into terminal and type su [enter] reboot [enter] and when it turns back on its usually doing bettery with the battery
as for opening programs, would advanced task manager serve the same purpose (closing apps that arnt needed and using memory, because if its using memory isnt it in some way using battery power?)
Thanks.
I am porting CommMgrPro to Android (Similar to Locale but much more powerfull). In this way I will switch to 2G, turn Wifi off, disable connections, etc, etc, etc automatically depending on my location/weekday/hour.

Hi All
I have a brand new G1 and, like you, I was suprised by the short battery life.
I also thought about selling the phone but apart from that problem I like it very much.
I noticed that the permanent 3g wireless connection was the real draining battery application.
So the solution I found now is: to disable the permanent connection. I downloaded APNdroid application from the market and I use it everytime I need to toggle connection on and off.
I also tried to leave the WIFI on and i saw that it does not consume much battery.
I did not tried with the GPS.
I am using a good tool to toggle and to fine check the battery level: Useful switchers
I can now say I am pretty satisfied with the phone.

Yes. It was the same problem there was in HTC Hermes/TyNT and TouchPro/Diamond. I created bandswitch in the past and will create two little toggles to switch 3g/2g with and without time limit....
Conditioning
Try Conditioning the Battery...
I have gps on, 2g, brightness at 50% and screen timeout at 30 secs, everything syncing and I get around 5 or 6 hours of use...just like the company says I should.
Run your battery completely dead...
Charge your phone for around 8-12 hours...
Repeat for about 6 days...
You should see improved battery life.
I have 3g, wifi, bluetooth, brightness at 50% and screen timeout at 30 secs, everything syncing with 1-2 hours of music/video with 30 SMS, about 20 mins of calls......I am now getting about 8hrs on the new ones from HTC (the 04).
Interesting Battery
Well now that I have had a week of use I have noticed that the (old) "02" batteries would last about 4-5hrs and go until 1% before turning off, with a slow count down. The (new) "04" batteries stay at a high number (about 6-7hrs) until they get to 15% and within a few mins turn-off....as I recall I saw postings of 'quick' count downs, so I wonder if you either get a slow drain down with about 4hrs of use OR about 6 hrs of use with the last 15% a very quick shutdown....I'll keep monitoring these new HTC batteries to see if it was just one of those "weekend" things or if this is the trade off...was caught off guard as I had been getting 30 mins or so when I had 15% left and the G1 would stay on until 1%..."teach an old dog new tricks".....
Hi guys,
I just want to know, what battery life are you guys getting with push email turned on. I have to charge my phone almost twice a day with reasonable use.
10 emails
1 hour calls
4 sms
1 hour web browsing
(no wifi or gps)
I can get 3 days with push switched on if I only use 2G and don't use the phone very much.
ie. push isn't a big battery drain in itself.
Maybe push is not big battery drain but being connected to 3G or HSDPA network is BBBBBBIIIIIGGGG battery drain.
I can get through near the week (5 or 6 days) making a few phone calls and SMS with Data Off whereas with 3G on, I will barely last 2 days (and surfing in the train when going to work (2h), battery will not last a day !!). And as push mail implies data on, I would say that it has an impact !!
3G kills the battery.
You can still push email through 2g.
I wonder if someone can create a program that will automatically switch the modes on and off depending on the amount of data being transmitted?

still nothing out there to switch it to 2g when the screen is off huh?

THAT! would be an awesome feature.
Data = radio being used, display = live wallpapers and the amount of time the screen stays on plus other additions are a big battery drain but sync in itself isn't that bad even on 3G and I have a G1 with its crappy battery.
Check Settings...About Phone...Battery Use to see what is using the most power. This can help identify unexpected battery drain.
For example some people also forget about widgets that use data like the weather and news widget. To maximize battery turn off all "background data" apps that you don't really use.
Also get Advanced Task Killer and set it to auto kill apps that you don't want running long term (be sure to setup the exclude list for those you want running).
You can use the Power Control widget to enable and disable unused items like Wifi, bluetooth, GPS, and background data.
Set your screen brightness to as low comfortable. On my phone the screen uses the most battery so this is important. You can use the Power Control widget to increase brightness quickly if needed.
Use 2G to save battery. For most stuff it's really not that bad. Use Wifi when you can as uses less power than 2G and is faster than 3G.
I use my phone a lot and it lasts all day. I don't really care if it lasts longer than 16 hours or so if it does all the fun stuff I want between charges.
^Excellent tips! Welcome to XDA!
thiis thing dies on me really quick, at home not as bad when I'm on wifi, but i left this morning from my house, and by the time I got to work 45 minutes later i'm at like 90% and i've done nothing on the phone, not a thing, no text, no voice calls. time without signal is 0.
then of course I get to work and time without signal jumps to like 22%, but still, my blackberry didn't go dead in half a day. i'm running the mixup undervolted kernal and the epic experience rom.
I do run gps and normal phone settings but turning them off is really not an option, especially for my wife that just needs a phone that works and isn't dead before she is out of work, and she doesn't even use the phone.
am I doing something wrong or is the battery life really this crappy?
and it was worse before the new kernal on DI18, and way worse before that.
i use the same set up i got 10 hours under pretty use
try turning gps off at work
So what are you leaving on? 4g? Gps? WiFi? I found that using black wallpaper helps.
wifi and gps are always on, it seems its TWS that is killing it. at like 22% right now. battery is down to 83% right now 2 hours off charger. no voice calls or text calls.
If you are getting a tws of 50% then put your phone into airplane mode for about 10 seconds and then switch it back, you will see a dramatic decease in tws

Here's a few things you can do ...
1) If you have Sprint service in most places, turn off roaming (Settings, Call settings, System select, Sprint). This will disable roaming period so that all roaming services are disabled (i.e. you won't ever see the data roaming guard).
2) Download JuiceDefender beta (this turns off all data, i.e. Wifi / 3G, whenever your phone's screen is off, if you purchase UltimateJuice with it, you can schedule it however you want, and you can choose to allow some apps to always allow data to go through). This saves me a LOT of battery since my screen is usually off.
3) Try the TWS hack mentioned in the earlier post, it should be fixed in DI18, but some people are still seeing high numbers there.
4) If you're rooted, get an app like Autostarts and disable the DRM service from ever running. This was found to be a battery killer.
The biggest battery drainer of them all is the GPS, and then 3G. If you can minimize your uses with those, you will maximize battery life. Also, use Wifi in areas that have it because Wifi hardly drains battery at all compared to 3G. I haven't seen any kernel really that gets much more battery life than stock, so doing these things will help. I love the Epic, but the battery life is a real downer for me too. I've gotten a full day's use (medium use) at times, while some days it hardly lasts at all.
Yes do the airplane mode trick and turn off gps if you are not using it and DO NOT USE JUICE DEFENDER i get 45 hours battery life without it. that app runs constantly in the background and uses more battery. Juice defender is for lazy people that dont know how to find these data and sync settings that are already on the phone or you can download an app that will let you toggle whatever setting you need. Set emails to sync once an hour and if it is really a priority then go into the email account and push refresh.
If you are really getting 45 hours of battery while actually using your phone then will you please share all of the settings that you have that give you this kind of battery life

Use SetCPU, it will turn down the processor while the screen is off. Helped alot with battery life. =)

I wondered if that would do anything. Considering how AMOLED works, dark themes and wallpapers *should* help battery life similar to reducing brightness.
Auto-Sync does some mean damage if your settings are too frequent, too. Try not to use Facebook/Twitter/Myspace integration, if possible, or disable them from syncing automatically, and sync them yourself when you feel the need.
Okay I don't know exactly what I did/didn't do but my battery problem seems to be greatly improved. Lets start with my details. Before 2 days ago. No matter what my use my battery drain would be approx 6-8% an hour. If I took my phone off the charger at 11am by 4pm I would be around 60%. GPS/4g/wifi off. Screen brightness set to lowest. tws not too bad. Using both the tws trick and drm stopped. Usually 2 or 3 phone calls 5-10 texts 5-10 minutes of browsing. I had a task killer installed but never used it to kill tasks just as an app switcher. Even after the di18 update no major difference. So the other day I downloaded an app called system panel. Another task manager. I deleted the task killer widget on my home page but no the app. The first day I took my phone off the charger used it for about an hour then put it back on the charger for about 15 minutes. When I took it off the charger it was at 96%. I opened system panel and killed all apps (necessary services/apps restarted immediately) did tws trick and drm kill. Same use as always after 8 hours my battery was at 80% a 16% drop. That's 2% an hour. The next day I deleted my task killer and over the same period of time I went from 96% to 83% (13% lose over 8 hrs) Only a little over 1% lose an hour. The only difference that I am aware of was the deletion of the task killer widget and then the app completely.

Ditto, I'd like to hear what you're doing too ... even when I do not TOUCH the phone, I cannot get 45 hours. I think you're being a bit optimistic here.
Lmao No. Since di18 it has been great. I use my phone for a lot of stuff too. I have a live wall paper and rss feeds that update. email is set to once an hour. Now dont get me wrong if i play a game then it will suck my battery pretty good like 5% for ten minutes. i have a widget for sync settings. im rooted with ALL SPRINT apps removed i think thats the biggest thing. dont leave gps or other on if you are not using it. i do not have drm removed. i use full brightness. i talk a few times a day and dozens of text and web surfing. no juice defender or task killers. The object for me was to not have any unneccessary stuff run when it doesnt need to. so the phone is set to come alive when the screen is on not off. Check ALL APP and WIDGET SETTINGS FOR HOW OFTEN THEY UPDATE. I DO MEAN ALL. GO THROUGH EVERY APP AND CHECK THEIR SETTINGS ALSO the biggest drain is make sure you sign out gtalk or it will just constantly run. I shoulda posted my screen shot of battery life earlier sorry i will as soon as it reads 1d21h again. prolly tomorrow afternoon.... Rooted,cwm,galaxy rom and kernel, blue minimalism theme

i do the airplane trick, problem is it seems,when im on wifi, the life is great, battery is perfect, as soon as you go to 3g, it goes to crap, plus the service where I work is spotty as well. I don't know what to do, seriously I can't go through 2 years of great cell service that I can't use because the battery is dead. I mean if I could get through 10 hours it wouldn't be bad, but as it is now, i'm lucky to squeak through about 8 hours. and I have the mixup kernal that is undervolted and supposedly already messing around with the cpu. usually on 3g, no matter where I am pretty much I"m at like 10-20% TWS.
tws is 50% for me. just stop the data with sync settings then it has no reason to draw more. my house and school have terrible service. you are only losing battery life due to data that is going really slow and it takes way more battery to accomplish. i keep wifi on all nite at my house but my sync settings are off. i do this so its not searching for 3g because i have an airrave and wifi. i used the di07 mixup and was not happy with it. galaxy roms have been the least buggy and very stable with the best battery life. That might be my opinion but also genius dog doesnt have an epic yet so i cant trust his stuff when he cant see the impacts with the kernels he is making. but he does know code i will tell you that.

Holy crap 8 hour battery life is really bad.
Do you have any apps syncing? A weak signal with an app syncing can have a devastating effect on the battery life.
In my school building I get 0-1 signal bars and once I use the stock email app to sync my email every hour with 3G on my battery life is probably a third as good.
How?

Inside my building where I get a weak signal I turn off 3G and use the wifi to sync my apps regularly. I get a good wifi signal there.
If I can't get a good 3G signal in the building than there's not much I can do to my phone to make the 3G signal better (I think that's the cause for the battery drain).
This isn't a thread for when your battery drain is excessive on standby, this is a thread dedicated to figuring out how to simply get more power to the phone for extended runtime.
I'm using a 5000 mah external battery pack for extra charge, and it seems to be good enough to last me at least an extra day or two of usage, which is great. It seems like the only other options are cutting up the battery door to fit an extended battery from the evo 3D or just carrying extra batteries...
Best easy change for me was always using wifi instead of the network when at home and work. Made a huge improvement

So....how to get the most time out of your battery in standby?
As you've allready said:
One of the biggest improvements is possible by using a Sensation or Evo3D battery. With that i get a nice 1% per hour in standby. (It's actually a bit lower than 1%).
While not using the phone it's unnessecary to have 3G activated. Recieving emails and texts via whatsapp, viber etc via 2G is good enough. For everything that is more datahungry you can allways activate 3G manually.
Keep background data turned off. I use K9 Mail which works independently and Whatsapp recieves messages too. But a lot of other stuff doesn't syncronize which means less wakelocks and thus less power consumption.
Same with locations. As long as you don't WANT to tell google your every step you can keep network based location turned off.
If you need a location fix quickly you can allways turn on gps for a moment. After using the FasterFix app (i guess you need root for that), i get a gps lock in 5 seconds, so i can determin my location really fast and share it with others (for intance via whatsapp) without having to keep it on all the time.
And last but not least:
You probably don't need to know the current outside temperature every 5 minutes. So set that to manual update too.
Doing these things doesn't turn my smartphone into an overweight dumbphone with a battery problem and i get a maximum of over 4 days of standby time out of it.
Normally my battery holds for roughly 35 hours (1 day and 11 hours), but it's usually awake for 1/4th of the time serving as my newspaper and video and mp3 player.
/edit:
Totally forgot:
Use llama!
You'll never have to worry about forgetting to set your phone on vibrate while at work and setting it to loud at home.
You can configure it so it only activates wifi at home and turns it off again if you didn't connect to any access point after a set amount of time. I haven't had to activate/deactivate wifi manually for ages without having to worry about it constantly searching for networks and sucking my battery dry!

Exactly what he said, but you can automate a lot of it by using an app called Tasker. I use it to sync all data on my phone for 3 minutes every 4 hours so it's always up to date. It can also automate the GPS on/off depending which app I use so it switches on when I open CoPilot and turns off again when I close it.
Tasker can also replace Llama if you can find 'profiles. to do it. Llama looks pretty good though.
I think the biggest drain is the display. With auto brightness on, the sensor will monitor the changes in your surrounding every second the moment you turn on the screen. Turn that off and manually control the brightness save a lot of battery.
Or just use lower autobrightness script.
I use Invisibright. Long hold on search softkey + slide enables me to set the brightness to whatever I want in a second no matter what apps are running.

It is still useless as your sensor is still working every time you turn on your screen. The sensor is draining your battery. Not the brightness value.
Autobrightness sensor drain
So you think that there is a greater drain from the light sensor than from an uncontrolled screen brightness?
Interesting thought. I'll manually set my brightness level a round20% for the next charge cycle and see what effect it has, though I suspect that as my display currently accounts for 20% of battery drain it won't make all that much difference.
I use juice defender and I think its actually working.
