Maybe my battery is not trained yet, but so far, on my 2-days old n1, battey lasts for 4 hours (mid. backlight, no wifi, very little use).
Still running stock rom and not planning on rooting.
What I noticed is that in my battery drain stats show Display contributing to 80% of total drain. That's with display being on mid setting... is that normal? What is yours (esepecially for people with stock roms)?
Are you playing with the phone a lot? Like is your display always on? 4hrs still seems extream to me, I am rooted and runninng a custom rom, but even when I wasnt I never managed to get through the battery that quickly, and I use the phone a lot
Here's what I do to get good battery... I only keep backlight on like the a ****as hair..lol barely unless outside...... widgets are cool n all, but if there constantly updating thats polling your battery, live wallpapers are cool, but a battery drainer, I also keep gps, locations and bluetooth off unless using them, wifi also.. also the background applications setting uses battery but if ya want updating widgets no way around that...
Also look in seetings about phone, battery use and see what's eating your battery, I use my phone hours at a time so my display is most my battery drain which is normal, everything else is like 7 percent or less, mostly 2 or 3 percent. ....
I think thats all I do, but you may keep stuff on like widgets and that unfortunately eats battery..
I am running everything in my Sig. I have had my N1 for about 2 months now right around that. After a 14 to 16hr day with some heavy to mild usage I am still over 50%, but then again I have 3g turned off and i am only on Edge all the time since i am always around WiFi. So i would tell you 4 hours is a bit extreme but hang in there it does get better. I remember being around 25% for the 1st few weeks until it got better. Other wise do what Temperbad said that is the best way to go. Only widget i am running that updates every hour is my Weather one. Turn the screen all the way down unless it other wise needs to be up. I am sure that is what is killing your battery. Mine is always on the lowest setting until i am outside.
Sadly I'm rooted, but I will state my percentage too.
Weirdly, my display usage is only 15% on Paul's Desire ROM. Honestly I dont see how this may be - but that is what it says. My brightness is quite high too..
Yeah, I'm well aware about widgets and battery drain regarding 3G and all that, I've had PDAs for quite a while.
For comparison, my old and ****ty TP2 would drain about 30-40% of its battery with same usage that would drain my N1 dry.
I do remember that LiIons get better in a week or so of usage, but I wanted to hear what you guys are getting. Would love to hear from someone who's just bought an N1 like me.
It's under full warranty, so I'm not worried too much. Just an inconvenience.

I have my display set to "Auto Brightness," have a display timeout of 1 minute, have my email get synced every hour, and also use a live wallpaper.
My display accounts for 63% of battery usage.
Auto brightness will use more battery than keeping it low. Cause its constantly checking light density through the sensor to give it the correct lighting...

I agree, but disabling that, disabling GPS, WiFi, turning off 3G, killing all widgets.. ok yeah my phone will last me 2 hours longer, but it's also boring as hell.
Might as well go pick up a simple nokia for $10 - battery will last for weeks, but what's the point..
Not saying your advise is bad, it's a good idea.. just that all these advices to turn everything off - what's the point of even having a PDA then..

I've read otherwise, though I don't think that Auto Brightness is the optimal battery saving setting.
Obviously it's a middle ground between max and low.
Here's a report of my usage today:
~Wifi and 3G both turned on the whole time
~30 mins of MP3s with head phones
~20 mins of 3G tethering over Bluetooth
~40 mins of apps usage (mostly the Browser and the Gallery)
~8 mins of talk time
one 1 min update through the bootloader
have gmail sync turned on, also twidroid syncs every 15 mins
The Battery use app shows:
54% Display (active 6% of the time)
16% Cell standby
14% Phone idle
4% Wifi (active 51.6% of the time)
4% Android System
Right now 14h26' since unplugged, still having 43% of the battery left. The battery meter says 12 more hours until 0%.
All things considered, the battery life is quite good on my N1.
Edit: forgot to mention, the display is set to the middle setting with the Power widget, no auto brightness

Wow... that's some serious battery life.
Ok, some questions..
1. screen brightness setting?
2. how long have u had that phone (battery) for? Did it improve over time?
3. Is it rooted/flashed or stock rom?
4. you got any syncing widgets running (RSS/twidroid)? Live wallpaper?
Thanks a bunch for your input!

Just one comment. I keep Wi-fi and GPS on all day because Wi-fi sleeps when the screen is off and only polls when the screen is on if you're not using it. GPS is only used when your location is required in an application. i dont know why people are always like "you have to turn these off to get good battery life" (Notice wi-fi is 2%)
also i've been running 8 hours with moderate to heavy use (internet, music, phone calls etc) and I'm @ 40%. The drain from 70% - 40% seems to go so slow compared to 100% - 70%.

Your right... about the updating widgets and wallpaper, they do make the phone funner.. but why need gps on when not using, or bluetooth, or wifi? Just simply turn them on when using...
So much going on with this phone I can say its good pretty decent battery....
Anyone know how to make my gmail sync every hour instead of instantly?
When I got my Nexus my battery was just as poor, but after using it for a couple of weeks I'm getting about 10 hours usage with medium brightness, WiFi, and gps.
So just give it some time and it should fix it itself.

Your phone or battery is defective. Call HTC for a replacement.
I know battery issues have been discussed over and over in this forum, but I have a question that I couldn't find the answer to in this forum.
I have an unlocked rogers x10 that's updated to R2BA020 that I'm using on Fido network, the phone is always roaming because I'm on Fido.
I'm thinking this is why my battery life sucks. I tried everything, task killers, juice defender, dim screen, full discharge.
Does the phone use more juice if it's roaming?
Yes, but it doesn't make a very large difference. If you're worried about constantly roaming, take a look at android, which let's you turn off Amsterdam on 3G.

Have you tried spare parts or something similar to check your battery usage? It lets you see what component is using the most battery. Even the Battery Usage option under Settings->About Phone should tell you where your juice is draining.

I'm still having battery life issues as well on my Rogers x10a.
I was at 100% as of 12:00pm and it's now at 87% 5:00pm.
According to the battery info I've used:
Voice Calls - 30% (10m 35s)
Cell Standby - 28%
Phone Idle - 22%
Display - 11%
Android System - 4%
ADW.Launcher - 3%
3G on, WIFI off, BT off
No idea what is draining my battery so much
I'm on Fido as well, though I don't see a roaming icon anywhere.
Are you sure you're roaming?

2.6%/hr with actual use (not sleeping overnight) is not bad at all. a 4inch screen, 3g connected all the time smartphone will not get great battery life if you actually use it. many people talk about how they get a couple of days or more on a single charge but there is no possible way for this to happen unless you are barely touching your phone. the best i can hope for is a full days use as i use my phone all day and evening.
sometimes an app sits in the background and uses lots of juice, so if you want to make sure that is not happening you might want to do a hard reset and not install any apps for a day and see how battery life it. you can add back apps slowly so that you will be able to tell if one is causing your phone to use too much juice.
the other things you can try is not to use widgets that auto update all the time or try locking your phone to 2g for the day, turning screen brightness down to the lowest level when possible. stuff like that will help. since i updated to the r2 generic rom my battery life has been good enough. i could always use more, but i use my phone too much to expect more.
Thanks I use my phone a lot as well but hearing all these awesome battery life stories had me expecting more. Guess I'll live with what I have.

It drives me nuts too but the reality is that we all use our phones differently so while some people are happy getting two days of use by barely using their phone I just can't do that. I rely on my phone for too many different things, so if I can get through one day I am fine. It was a shock for me initially as I was using a blackberry 9700 and it had a very small screen and long battery life

I took my phone off charge 6 hours ago and I have 79% left as I type.
I did a 5 minute phone call, 10 minutes browsing, 2 minute YouTube video and I turned on WiFi for 30 minutes and Bluetooth for 45 minutes.
I checked the settings and it says:
Display 48%
Standby 18
Phone Idle 13%
Voice call 13%
I've been switching options on and off for the last few weeks that I have x10 and the conclusion is => turn of APN when you don't use it and the battery last for 3 days. Only problem I can think of is mail push but you can always check mail every 30min. There is this "APN on/off" widget that makes switching APN on and off pretty easy so there shouldn't be too much problems.
Doesnt make a difference here.. wifi and 3g cane my battery!!

Update:
I removed JuiceDefender, and I installed advanced task killer, and APN on/off widget and the battery life is much better now. I turn data off when I'm not using the phone and I kill tasks about 3-4 times a day. The screen is dimmed to 15%.
As per Android system info:
Up time: 1 days, 3 hours, 1 minutes, 59 seconds
Up time (without sleep): 0 days, 4 hours, 23 minutes, 8 seconds
17 % battery life left
I checked the settings and it says:

Standby 29%
Phone Idle 22%
Wifi 4%
Android System 3%
Broswer 2%
Quick question for advanced users, I noticed that Android sys info says up time without sleep is just over 4 huors while the phone settings says 2h 33m, any idea which one is more accurate? I'm assuming up time without sleep = time screen is on.
Switch off GPS. I read about it and how it improved batteries. Bloody true. Its great advice.

Time without sleep = time screen is on
IF nothing isn't keeping the phone awake.
The phone setting says 2h 33m because it counts the time that the phone was asleep AND the screen was off.
The real percentage is the one Android sys info gives you.
It is rather normal for the phone to have slightly more awake time that screen on time, as some applications work even when the screen is off (push Gmail, the clock, some widget etc...).
As long as your wake time is not 100%, you're just fine.

Another HD user here on a mission to maximise battery life!
I think you have to accept that whatever features you want to use will take a big chunk of battery when actually using the device especially with this screen, so looking at minimising the battery drain while the phone is in standby which it is for me the vast majority of the time.
So far I have turned off any wireless service except cell phone and use push email on a couple of email accounts that are not particularly busy. Other apps I use I have set to only sync when I choose it and there are only system processes left running.
By removing and disabling various apps and functions I have managed to get my CPU utilisation down to around 0.7% on average when in standby. Left alone my battery life drops by about 5% per hour meaning if I do nothing with the phone I get about 20 hours of standby max.
Has anyone else looked at this and managed to get a lower standby CPU utilisation?
I'm using Systempanel to monitor the process history.
Hello
If you root your phone either temp or perm then you can use Set Cpu. With this you can push the processor speed right down when screen off. Using this my battery only drains 1-2% per hour while on standby.
Great tip. Thanks very much. I shall give it a try
5% drained in standby, wifi off, mobile net off? That sounds like something else is eating it. Dont you have network signal quality problems? I used to have such drainage when the antenna was covered, poor signal. Then in battery usage, cell standby rocketed up. If i take care that antenna is not covered this goes away. This on htc z. I could run the phone in standby for about five or six days. (No wifi, no net, just voice).

I keep reading about this new improved battery life with Gingerbread, however I've found the opposite.
By the time I leave off work, my battery is typically at about 84%, that's with no usage all day. Today is the first time at work I've been running Gingerbread, I'm only half way through the day and my battery is already at 69%, if it keeps draining at this rate, it's going to be down to about 30-40% by the time I've left off!
Did you do a factory reset ? It helped me a lot, i'm at 4 days 6 hours with 16% battery remaining.
Also check if you aren't scanning for wifi 24/7.

Have you checked what application is draining the battery?
Google
I had dreadful battery life and discovered that Latitude was polling constantly and also Google Talk.
Make sure you sign out of both and see if it makes a difference.
... and disable "Tell HTC" service, it'll help as well.

Disable? with force close?
Right, I've disabled Tell HTC, signed out of Google Talk and made sure it doesn't sign in automatically. I've also signed out of Latitude.
The top four things listed on the battery usage are:
- Display = 34%
- Wi-Fi = 15%
- Android System = 13%
- Dialer = 13%
All others are pretty much under 10%.
I'd rather avoid doing a factory reset due to the amount of information and length of time it's taken me to get everything set up. However, I made the mistake of thinking that Wifi wouldn't be used if mobile network was on. My plan was that I would then connect straight away to Wifi when I was at home, and when it lost the signal it would switch to my mobile network. Well, this seems to work fine, however obviously as shown above, it's still using a fair bit of battery. I think I'll just start turned Wifi off completely until I'm going to use it.
For enabling/disabling wifi i use https://market.android.com/details?id=com.sas.inappwifitoggle . Long press search key and it gets enabled or disabled.
- Display = 44%
- Wi-Fi = 15%
- Android System = 23%

Check out this thread about the Dialer issue:

My battery life hasn't improved either.
With moderate to heavy use I get about 6-7 hours only. My brightness is usually set at 30%
Display - 69%
Dialer - 8%
Cell standby and others - 4% and less
Is this normal?
Could you give us some more information here ? I mean what type of system are you using, Stock, or some type of ROM ?
I'm running LeeDroid's latest ROM, 2.3.3 and have Green Power installed so data gets turned off when my screen is off.
Auto-sync is turned off too.
In regards to mail, twitter syncing I set mine to every 6 - 12 hours.
I have had gingerbread RUU for 1 week now. With Froyo I used to get 15-30 hours depnding on wether I used 3g or Wifi(Wifi more conservative of battery). Since GB update my maximum battery lasts for 12 hours. I have noticed severe battery drain uder WiFi. Previously with 2.2 with the phoned switched off at night with Wifi enabled, the battery would drain approx 7% in 7 hours. Well today I did the same test switched off phone,left wifi enabled and the battery dropped from 90% to 46% in 7 hours which equates to 7% an hour with the screen off!
This is unacceptable! I sent HTC an email to expalin this but all I got was list of ways to reduce battery life such as swich off wifi, move to 2g, switth off live wallpaper etc etc. But all of this is absolutely of no use if the battery is draining at 7% an hour with the screen off. As I mentioned before with 2.2 the wifi drainage was small approx 1% with screen off.
Can someone suggest a solution?
1)Should I contact HTC again?
2)Try a custom ROM?
I havent tried a custom rom yet as the phone has been runnning well minus poor battery but I may have to if a solution cannot be found.

I noticed the same drain as well when I updated, but after a few days of testing I found that the problem was with one of my apps widgets. My guess is that the app is not efficient on gingerbread.
After removing the widget, everything was fine again.
To sum it up, check your apps.

when you say check your apps what are you using to find out whats running what.
Also how do i know what i can stop without making other things crash on me
for example. i do not use my sense account so can I shut dwn all things to do with sense that are running without risk?
I had the issue with battery life too. Just get the wifi switch on your homepage and turn off if you're not using it. Otherwise it constantly scans and leaches your battery.

i just switched to 2.3.3 and its fine, try another rom.
I've noticed that when I attempt to power on my Transformer a couple days after powering down that the battery is completely drained as if the device was never shut down. The only way to power on is by plugging in to an outlet. I was under the impression the battery would last longer than a few days when powered down.
It definitley should, if I just put my tablet in sleep and leave it all day, it loses about 1% per day, so turned off I'd expect the same or better.

Wow, mine loses about 10-15% overnight. The same as the op... The batch number is B50*****
Mine too drains battery when in sleep mode. Also B5 build...hope an OTA update will fix it soon and that it is not a hardware problem.
Same here and I'm stock w/out root...

Mine was in standby with airplane mode on (wifi off) - B3OK
100% battery was down to 64% by the morning. In 10 hours lost 36% battery
With all the talk about keyboard dock drain - I think this is more a important issue.
I have a B50 tablet, and mine only looses 1-2% per day if left in standby. This is in Airplane mode. Dunno what you guys are doing to loose half your charge over 24 hours.
Probably background apps. Some apps force load themselves (Like Thumbs keyboard and TapaTalk which wants to prevent standby on installation according to someone else on this forum).
I am also experiencing this issue. When I put the tablet on standby the battery continues to drain. When I when to sleep last night the battery was at 30%. When I turned it on this morning, it showed 4%!
This is unacceptable. The battery saving option is turned on. Is ASUS aware of this issue?
if you look at the battery info chart, does it show it becoming awake shortly after using it and staying awake for quite some time with the screen off?

B50 here. 0% battery drain. woke up and used it to check XDA for a little bit and went down to 98% but that's to be expected since most tablet/phones don't like to stay at 100% battery level to preserve it longer.
airplane mode while sleeping.

it would also be helpful for you guys to say what ROM / kernel you're using.. and if you're stock, say stock. hence why people on XDA have this stuff on their signatures
I am on stock. Could it be because I have some apps running that are causing this battery drain? Or is it the microSD card?

microSD wouldn't drain your battery. I would say check your battery usage but that's disabled on stock.
- Check your Google Accounts in Accounts & Sync. Is Picasa Web Gallery checked for syncing? I heard there was a bug about that and it consistently drained the battery even when you're not on Wi Fi.
- Any syncing apps, make the interval longer or make it a manual refresh if it's not important.
- There is a bug where the tablet may be trying to interact with Mobile Data. I'm not sure why but people on other Honeycomb tablets have reported the same thing. You can bypass this by activating Airplane mode. You can still use WiFi when it's in Airplane mode.
- I personally don't use any SetCPU profiles. They tend to do more harm than good. Just my opinion, it's up to you but if something's going wrong with your battery. Try disabling them and see if you notice a difference or not.
- My WiFi sleep policy is set to "when screen turns off." Even though I select this, my tablet still gives my notifications on emails and stuff. Seems to be working well for me.
- Don't use any task killers.
- If you use a kernel that supports undervolting. Play with the settings and undervolt. My kernel that I use doesn't support it but I still get good amounts of battery life.
- I don't overclock. This could drain your battery as well (unsure, but it probably does to a certain extent). At 1.0GHz my Transformer is fast and responsive so I don't OC anyway. I only OC for benchmarking for fun.
Many people have said to disable GPS. But in fact, GPS is on demand! Even though when it's enabled, GPS is only used when a app or the browser requests your location from GPS. I personally have it on, but it's up to you really.
There. I just compiled some battery tips. Hope they help.
A true way to find out if something is severely wrong is to put your tablet into Airplane mode while sleeping. When you wake up, check how much % you lost. If it's over 5-7%, I'd probably say something is wrong with your setup.
^OK thanks . I will give it a try when it is fully charged.

At least check if Picasa was syncing. If it was then that could of been the source of it. Let me know?

OK I have unchecked the following syncs:
- picasa
- calendar
- Skpe sync
I have also turned on airplane mode. Lets see what happens.
So how do you tell ???
How can you tell which model ( B30, B40, B50, B60 ) you have ????

It's the serial number. Check the sticker on the dock for S/N or on the box that it came in.
After making the changes I described in my last post, I am now losing about 2% every 4 hrs. That is 0.5% every hour on standby. Much better than before but I believe others here have a much lower battery discharge rate.
I will continue to monitor the battery discharge rate under different scenarios.

Same problem, if left overnight looses around 30-40% of charge and looses 3-4% as soon as I disconnect charger. All sync is of, email check is manual. Juice defender is installed and on. So I have checked its logs and it says that almost every 10 minutes tablet uses WiFi connection. Went to Settings of WiFi connection and unchecked Notice about open Wifi spots and checked Always on when cgarger plugged in instead of "Always on". Will see how it works now.
