Could too enlighten me further what exactly is the 1500 battery?
Pooped from my Samsung Vibrant using XDA app...
Dont mind the skidmarks...

^ the stock battery is 1500...

Indeed I've gone overnight without a charge and heavy usage the next day and still wasn't 1/2 way depleted. I think the Super AMOLED has a lot to do with the awesome battery life.

"HEAVY usage" is relevant. I've had my Vibrant for 3 days and the battery is unimpressive to say the least. Hopefully, it will improve.

I am not sure what you have to do to prolong the battery life besides not doing anyhting, i.e. I was in the woods this weekend with no service at all, kept the phone in flight mode, used it to snap 3 pictures and 3 vids no more than 1 min each - the result is impressive - unplugged the phone at 7:30AM and by 4PM I had 70% left. Woohoo, I guess, the phone did nothing for 8.5 hours and only drained 30%.

I unplug my phone everyday around 6am and as of now, which is 7hours later I'm sitting at 92%.
What have I done on it as of today? 4 phone calls, 3 emails, took some photos.
Things I don't do all day.
Watch avatar over and over, let it idle on 3G for no reason, let it idle on wifi for no reason, turn off auto brightness.
I do have a regular schedule of charging.
I plug it in around 11pm turned off
I turn on my phone around 540am and leave it on the charger. I'm always greeted with the Its full unplug message around 6am.

how come your display use is only 8 percent mine is like 74 percent even tho i have it set on the lowest possible......

Thats saying out of all that time his phone has been on, his screen has been on 8% of the time.
If you use your screen a lot the number will be higher and I'm sure the more battery that would be used.

Great results so long as you don't need any network access for email accounts to work. That's not really an option for a lot of people. I have to have either 3G or WiFi on at all times to receive emails. SMS messages will come in over GSM so if that is what you do rather than email than you can turn off WiFi and 3G and still do texting.

Email works just fine over 2G (EDGE). I've found that setting it to 2G-only while keeping WiFi enabled (setting to stay on during standby) if in one location for a long time works better than keeping 3G enabled.

What is your build date? Find manufacturer date on box or inside phone.

I get good battery life... only gone down 1% since I unplugged it from being fully charged in 30 minutes with the display usage at 84% with GPS on.

yeah, tomorrow, i'll try to leave wifi and 3g on all day and come back with the result.

Checked my standby draining today. Lost 10% in 7 hours and 10 min. Look good, no ?
This is with: Google account sync calendar and contacts, push exchange email, 3g, auto sync
Must add that Tasker is also running and set to check everything to 30 min intervals

I have owned this phone since day one and am convinced that wifi is the biggest battery killer for me. I unplug it at 730am in the morning listen to live stream podcasts on the way to work and back (35 min commute). Make a few calls and texts, check all my normal websites on my breaks and when I get home at 630, I still have about 60%. In the settings I leave gps off and wifi on so when I get home its automatically on. By 930 the phone is at 15% so I am convinced its the wifi.
Having a screen this nice is worth the mediocre battery life, its actually better than my g1's battery life, so I am happy.

2800 Mah batteries on the way...

I'm not sure, I think it means of all the battery that has been used, 8% of it went to the screen. I would also like to know how you got that fantastic number! I usually have my brightness on minimum since I mostly use it indoors, and the screen is by far the largest consumer of battery power, even on days where I mostly listened to music (local, not net streaming) with the screen off...

I'm definitely getting better battery life out of this than my previous smart phones. Currently at 55% 1d20h unplugged. Light use, but still.

MASSIVE battery drainage overnight with ZERO usage (with screenshots!)

My battery died overnight with NO usage.

Sorry that was a separate issue I made that reply about, where adb wasn't finding the phone. Resetting my computer fixed it.
I'm going back to Netarchy 4.1.8 and disabling SetCPU first, then if that doesn't work will do a full wipe, reflash Fresh and restore from my Titanium backup. If THAT doesn't work I'll flash Froyo Fusion and go back to stock HTC kernel.

To me, what's interesting isn't necessarily the drainage itself (as crazy as as that drainage is), but the fact that the drainage isn't tied to any device or cpu usage. How does that happen?
Normally, wouldn't you see matching peaks? At least between CPU and battery?

That's my expectation as well, hence the kernel rollback and SetCPU disabling, as those are the only components I can identify that would have a passive influence resulting in the uncoupled usage/drainage.

Just to report back, did a full wipe and reflashed Fresh 3.2.0 and netarchy 1.8 and drainage seems to be back to normal. I'll stick with this for now, or maybe go to nerachy 1.9 beta to try the addtitional power savings of HAVS since it's an easy rollback.

I've paid attention to all of the threads about battery life. I've done my best to optimize my device for maximum battery life but I can't believe what I'm seeing. Last night, I left my house at 5:30 with a fully charged device for a block party. At 10:30 last night my battstat widget had my battery life at 83%. I am using setcpu for screen off profiles and a few others. I have wifi and 4g off, always on days unchecked, Google Talk auto sign in unchecked and only received about 15 emails (screen was off the rest of the time).
I am rooted with baked snack 1.7 with kernel #6. What gives? Just since typing this post it has dropped to 78%. Turned screen off overnight and woke up to 51%. This is crazy.

What about your roaming setting? I would assume it has something to do with trying to find a signal also. I would suggest turning off everything. No widgets, no nothing. Run the phone for only two days with nothing on. I would go as to even turning the airplane mode on and running basic phone for a day. If that doesn't work then its the ROM or you didn't fully stop a app or delete it.
If you want it fixed you are going to have to put in some serious testing time. I'm amazed that no one has made a diagnostic app yet.

That's not bad. The phone really only goes to about 90% charge at most unless you use the calibration method to charge all the cells. So after 18 hours it was down about half.
Check your Accounts/Sync settings and turn off Facebook, Twitter, Gmail, Google Calendar, etc. syncing.

Stay away from fancy kernels that claim to have BFS, HAVS, WTF, BBQ and simply stick with Netarchy's 4.1.8 CFS Kernel. Also, don't use SetCPU, contrary to popular belief, it does NOT help with the battery at all,in fact it makes it worse. Do that and then report back. I'm sure you will notice a major improvement

Try turning your data completely off. A lot of apps automatically have access to certain functions of your phone and will tend to run in the background even after you "kill" them. With your 3g off they will not be able to do this. I've found that 3g is the main source of battery depletion and if you're like me and have way too many apps either use your power widget and turn off 3g/data or roll with a charger everywhere you go.

That's crazy. Since there's no correlation between battery usage and any function do you think maybe you have a faulty battery? Please let me know as this is very disturbing.

I'm going to go out on a limb and just say your Time Without Signal is around... 40-70%.

Nah, I was sleeping and I charge my phone by my window in midtown Manhattan. Full bars all night.

Install Spare Parts. Look up battery usage and check partial wake usage. Something is keeping your phone awake when it should not be.

I've had similar battery drain issues when using profiles under setcpu. If I disable those my battery usage tapers off to a much more predictable state. Although Google Earth requires a reboot for some reason before it stops sucking down the juice.
CM6, snap 7.6 CFS

ditch setcpu, its not needed with the new 3.28 base. With juice defender on and light/medium usage i can get about 24 hours per charge

Battery question

Hi!!
I have one lg p500, with this mobile i need to charge the battery only at 3 days (one call per day of 30minutes (3g mode), wifi usage 30minutes per (80211b), no 3g data usage])
Is possible equal with milestone 2 downclockin the cpu and using other tips?
Thanks!!!

Downclocking just use SetCPU.

Ok, but it takes effect in battery usage?

Yeah. By underclocking your CPU it dramatically reduces the number of cycles per second. So the slower it performs the less power is used to do one cpu cycle. Something like that.

The normal (i guess) battery duration of mile 2 is 1 day, downclocking to 600mhz is possible take 2days without charging?

Yeah. It is possible. But your system will slow down a lot.
Also make sure u have profiles in SetCPU. Maybe like for "Screen Off" have 300MHz min and max.

Motorola announces the same talking time and usage time for Milestone 2 and Defy, its really true?
Milestone 2 have better hardware and lower battery (1400 vs 1500)
Its fake info from motorola or not much difference between mile and defy?

100mAh is not really much difference so you can say that they are nearly the same battery life (give or take 1 hour maximum).

Sure? The reviews says "nice lifetime battery" for defy and "poor battery" for mile2, using tips, customs roms, and all more what is the lifetime of your mile2 today?
Thanks.

Please keep in mind that the Defy originally shipped with Eclair (2.1). That could be an explanation.
My Milestone 2's batterylife is about 36 hours. This is with data disabled during sleep and 2G instead of 3G when I'm at the office.
Downclocking the CPU might improve batterylife, but keep in mind that active data connections are draining the battery.

My atual mobile (lg p500) battery life is about 3days.
-Always in 3g network (24h per day)
-Calling about 30minutes per day (3g too)
-No 3g data
-Wifi usage 30minutes per day
With the same in your mile 2 your battery usage is about 1 day huh?
Thanks.

I think, If you don't use 3g/hspa data and no gaming (3D games), 1 charging per 2 days should be enough but no more...

When the 3G sign in the notification bar shows up, the device connected to a DATA network. When you disable data, you'll still be connected to 3G, but there's no data connection available.
The battery drainage is because of the data traffic. My MS2 uses data (keeps in sync) using 2G.
When I read about the way you used your LG, you simply didn't use any (a lot of) mobile data: no sync, no push etc. Disabling all of this will certainly give you your precious 3 days.
So conclusion: what you need to do is disable data traffic. Go to Settings, Data Management or something like that and disable Data traffic!

BTW. I did a comparison between 3G/HSPA and WiFi battery usage. Here's what I got:
3G/HSPA power usage:
-not used (just turned on): 0mW
-used (speedtest): 600mW
WiFi power usage
-not used (just turned on): around 25-50mW
-used (speddtest): around 750mW
So WiFi needs more power than HSPA!

Where did you get these tests from? I have the impression that Wi-Fi uses much LESS power than 3G on Milestone2. Keeping data sync on, my batterylife is about 3 days if using only wi-fi. Using 3G my batterylife halves.

You can use DCSwitch app from market to completely turn 2G/3G data off.
Sent from my Milestone 2 XDA App

my battery life can last for more than 48 hours without charging with: let's say about 10-15 calls (30 minutes), 20-25 sms, some angry bird, facebook, android market and email.
the configuration is something like this:
- use juice defender and set it to aggresive profile.
- use setcpu (for rooted phone) and create some profile (screen off min 300 max 300; temp > 40 min 300 max 600; battery < 30 min 300 max 600)
- always use 2G (use 3G only when download from market)
- turn off data transfer (only turn it on whenever I needed to)
- gps, wireless and bluetooth off.
a lot of guys in the forum say that you can use launcher pro to disable motoblur widget that drain all of our juice, but I think as long as we disable the data sync(facebook, email weather or whatever), we still can save our juice. I'm pretty sure about this even I haven't tried launcher pro yet (I kinda love motoblur theme).
How about you do launcher pro affect battery use if we already switch off all data sync??

Crazy Android OS CPU usage

I am getting crazy CPU usage from Android OS, which is currently sitting at 52% battery usage. The CPU time of Android OS is between 20 and 30 minutes per hour! I have tried freezing many apps, I have tried task killers, rebooting etc. I have WKE7 firmware.

android os does use more than the rest, unsure why, but somehow the battery ife is still pretty good
http://goo.gl/cyd1T
KE7 (stock kernel) , full sync on google stuff + 1 email on push + auto brightness + about 1H of display on time on this, 1d20min and 68% left.
sent 3-4 sms and did a bit of various stuff since yesterday.
Seen worse lol

I would be very happy with that kind of batterylife. Sadly, my phone loses about 35% battery while I'm sleeping. With medium usage, I would usually reach 12 hours of battery.

i rate my battery life to smth like "amazing" xD

Yes for me battery life on sgs2 is also very nice - I'm comparing to sgs and it is about 20% better. My heavy usage today was 5 hours of screen on with wifi, some gps, 2h of gaming, skype running for about 3h, and battery run for total 9h. Also I use 2 push email accounts and sync is on. I think thats really good. And typically when I sleep in 8h battery is drained for about 8% with all email and google syncs active. So this is also quite good. All that on KE7. Most of samsung bloatware frozen.
Sent from my GT-I9100 using XDA App

Been trying to keep away from these battery threads, but noticed today that I've gone from android system 12% to 30% and I've no idea why.
Still on KE2, and am probably a "light user" - black wallpaper, brightness 20%, screen timeout 2 minutes, some phonecalls, lots of SMS, music - lots of Poweramp - shown a few photos, occasional wifi, GPS ca. 30 minutes per day, don't sync, don't use my carrier's dataplan, no e-mail as yet, and no Facebook/Twitter/games/Social hub/accuweather etc ever - in fact they were uninstalled on day 1.
Got 36 hours from my last charge, am now on 79% after 16 hours. Still happy with it, but no idea what has caused this spike.... Will keep an eye on it.
My $0.02 worth.

I am really starting to wonder why some people have amazing batterylife, while others are having terrible battery life. I would be very happy with 18 hours with 4 hours of screen usage, but instead I am barely scratching 12, today has been even worse. 10 hours with 3 hours screen usage...

So far mine is 2hr 15 mins screen on time, mostly browsing on 3G, 13 hours on battery, and have 29% remaining. Its OK, but I wouldn't describe it as amazing. Roll on 2.3.4

the thing is on android battery life largely depend on apps and setup anyway

Yeh, I know. But I feel like I have optimized my setup as much as I can. No autosynching, email check every 2 hours, facebook, twitter and RSS updates ever 4 hours. No GPS, automatic screen brightness, wifi sleep on. No widgets pulling real time info.

mine has the stock weather widget and animated background - also wifi always on (that prolly actually helps ..)
also i used some gps,played short videos, youtube, recorded some vids and took a few pics (you can see i used it more heavily today in the graph)
im supposing a lot of this goes as android system (bug?) cuz its certainly intensive and isnt in the list (not even lower)

Get rid of the auto screen brightness. I find brightness of 10% makes a huge difference. This samsung screen might look great but in fact it's practically useless as it drinks power

with ke7 as u can see auto brightness doesn't seem an issue for me anymore
i like it because i don't need to set the brightness in sunlight when it's auto hehe

What is your CPU time on Android OS vs. total battery time? Right now my phone has been on for 2 hours and 14 minutes, and CPU time in Android OS is 43 minutes!

If you've read through the majority of these threads, what's weird is that some of you that have uninstalled and/or frozen specific apps are getting worse battery times than those of us that are bone stock and have everything whirring in the background. As an example I use Wi-Fi a lot and also Kies Air and connect to a Blu-ray player using Wi-Fi Direct. The Wi-Fi Sharing app never appears in my running apps after I turn Wi-Fi off. Yet some of you with tweaks that don't use Wi-Fi have it randomly appearing and eating up CPU time.
I've kept up with this thread and other battery threads and for every "ah-ha!" moment there's a post following it showing worsening or no improvement. Somewhere in one of the three battery threads there were some tweets from Google acknowledging the problem in running 2.3.3. with dual-core processors. I think other than for the mad scientist fun factor we're just beating a dead horse and 2.3.4. is going to have to be our salvation. There's not even any assurance that a cooked ROM sans all the Samsung tweaks would work any better if the issue really is a core-OS problem.
Back to our ongoing debate...

Hello all

Hi everyone, I'm new to the forum. Recently got a Nexus S i9023, very happy with the phone. Messing around with custom ROMs, currently running latest NSCollab with latest matr1x kernel, 9.5.
Any suggestion from others who have the same setup? Curious about battery life, as I seem to not get the same average-use runtimes as others who post in the dev forum.
Thanks for feedback!

You're running the same setup that I am, and my phone easily runs 20+ hrs with the stock battery.
I run 100/1000 mhz, smartassv2, -35mV undervolt, deep idle enabled. I'm a bit more active in power management than others; leave 3G off unless I need it, use only wifi while at home, and decrease screen brightness to bare minimum.
Usually take advantage of power conserving tricks such as dark wallpaper, inverted browser colors, minimal widgets, etc.

I am lazier than you- won't probably start switching 3G on and off. I switch it to 2G when the battery is down and I can't get to a charger.
WiFi on only as needed of course. Will play with undervolting soon.
DeepIdle though- it should be the ONE thing that extends the battery by hours, although I can't seem to see the benefit. Idle drainage is still 4%-5% every hour. Does it seem normal to you?

No, that's not normal. Check to see if deep idle is enabled and check for any misbehaving apps. My battery usage flatlines when the screen is off.
You can also try Juice Defender for automatic power management. It turns off the 3G radio when the screen is off, but still lets apps and email sync when they need to.

What app should I use for detecting high unusual CPU usages? Any specific good one in mind? I find that everything seems normal in the built-in Android battery statistics info panel...

Also, how do you feel about the battery charge "fix" that allows the battery to reach 100%? Does your 9.0 kernel have the patch too? I read different opinions about that, I don't mind some extra juice but I wouldn't want to see the battery deteriorate, since I often leave it plugged overnight.
Or maybe it's a fix in the sense that it shows 100% but it still charges to less than that?

You can click "Usage" and/or "Statistics" in BMW to see what's been using power. SystemPanel is also a good monitoring app, but it's a paid app.
Matr1x 9.0 does have the 100% battery charge feature (I'm currently using 9.5) but I'm not sure if it truly fills the battery cells or if it's just a percentage display trick. My battery charges to 100%, 1440mAh, and 4,187mV so I think that's a true full charge.
I'm still new to the Nexus, so I've not yet learned all the quirks and minutiae of this phone. Coming from the Evo 4g and I just switched to nexus a few weeks ago.

At idle time, phone still consumes more or less 15-20 mA, as evident from the graph. Yours seems to absolutely not drain current at all (your charge stays at 100% and your mA graph is at 0 for a good two hours)!
You could post a screenshot of your detailed battery history readings (bottom left button "History") when you have a chance. Just out of curiosity.
Thanks for the info you gave me so far!

-15 or so mA is not unusual at idle. Mine actually runs around -5 at rest. My Evo wouldn't go any lower than -16mA.
Been using the phone nonstop tonight, so I scrolled back a bit to find an idle period in the history. Sorry for so many data points... it updates every two minutes.

Welcome!

Pleased to meet you!
Braneless, thanks for posting. Now are those idle battery drains with data on? On wifi, or 3G, or 2G, or what? All other connections off?

I use 3G only when I'm out and about, but wifi is on at all times when I'm home. WiFi radio draws a fraction of the power that 3G does, so I just leave it connected.
In other words, the battery history figures are with 3G off and wifi on (set to never sleep with screen off).
Setting wifi to never sleep prevented random reboots with certain roms for the Evo - I just carried that practice over... not even sure if it's necessary for the Nexus.

I use NexusMV with latest Matr1x kernel and I use 1% overnight with airplane mode on.
After 24h I still have 58% left right now

Bad news.

I was testing idle battery drain again tonight. Got a system hang of some sort, had to pull the battery. Phone didn't come off of sleep. I was testing with WiFi off and 2G only. As you can see the battery went down 35% during the system hang, in just little over an hour.
I also noticed I don't get anywhere close to only 5mA drain in idle, even with just WiFi on, like braneless. Again, running latest NSCollab ROM with latest Matr1x kernel, 9.5.

Have you tried checking if there is this file in "/sys/class/misc/deepidle/enabled", it should be 1 if enabled, 0 if disabled.
I think that in some versions of the kernel deep idle would be implemented but not enabled by default.

This system hang is the reason why I left NSCollab. Too many times I woke up with my device not waking up (note: the alarm wouldn't go off either)
There's more people reporting the same issue on NSCollab, no idea what causes it though.

Did you undervolt the kernel? I had the same issue when I was running an aggressive -75mV, but it completely disappeared when I reduced it to -25mV.

Checked it, value returned was 1, enabled.

Matr1x 9.5 is an undervolted kernel, if I remember correctly, -35 mV. I flashed franco.kernel this morning to give it a try, seems like it has more recent bug fixes for deepidle mod. And is not UVed by default. I'll see what happens, and how's battery life with no UV.
Still wondering how braneless got just 5mA drain in idle. Would like to have his exact ROM/kernel/settings/tweaks/OC-UV setup posted!

You can also increase voltages using Proton Control.
My setup is pretty simple;
NSCollab Sprint 1.0.51
Matr1x 9.5, -25mV, smartassv2, deep idle enabled
ADW Ex launcher
Screen brightness set to 10%
3G off nearly all the time
WiFi used whenever I'm home
Autosync off, sync mail/cal. manually
That's it! Keep in mind that all phones and their chips are not built entirely the same due to manufacturing tolerances. Some phones can handle varying degrees of undervolt, underclock, overclock, etc. Power drain will vary as well.
