ok, I'm in a great mood, I FINALLY got my EVO to last from when I leave home to when I get back home with normal usage (no point in only sending texts and short phone calls - if that's all I'm gonna do I coulda got a razr!) but here it is including settings and all with usage details included.
ROM: Damaged Goods 3.5
Running: Advance Task Killer, Battery Indicator, Voice Dialer, Call Filter, Handcent SMS, and google voice just WOULD NOT stay closed!!!
Settings: Auto-sync off, automatic brightness, haptic feedback is off, background data is off
Other: I charged with an external charger that I got off of ebay, so the battery had a good charge to it
Usage Details:
1:59 pm turned on wifi and unplugged the phone
1:18-1:19 short phone call, dropped to 98%
1:47-2:11pm web browsing. Battery dropped to 91%
2:25-2:26 quick facebook check, battery dropped to 90%
2:43pm - checked e-mail, battery dropped to 88%
2:54-2:56 - 2 min. phone call. no change in battery
3:04-3:33 - turned off wi-fi, played some pandora + web browsing. battery dropped to 77%
3:40-3:41pm - phone call. no change in battery
4:15 - battery at 75%
4:16pm - internet (checked e-mail and facebook status)
4:58pm - battery at 69%
5:00pm-5:03 - phone call. battery at 68%
5:04pm-5:09 started playing music and doing the transformers movie puzzle
5:09-5:11pm - phone call.
5:11pm-6:10pm - continued music and transformers puzzle, let a couple people that stopped me asking about the phone play with this and that feature, did a 4g speed test (over 7mbps btw) and other things.
6:10pm - 49%
6:11pm - 11:08pm - phone placed in airplane mode while I'm working
11:08-11:42pm - picked up phone at 39% battery, then continued playing music and transformers puzzle
11:42-12:27 - phone call. dropped battery down to 10%
1:02am - battery down to 8%
now - 1:25am, battery still on 8%
Froyo has definitely improved my battery life, I used to couldn't get this type of battery life out of my EVO. Oh and here's the screen shot at the end of it all to prove the phone was actually USED, and not just sitting around.

to those that dont' know, when you see screen shots with a high percentage of phone idle and cell standby it means the person isn't really using the phone, just letting it sit, or only sending a text or something like that. Think about it - how much use is someone getting out of a phone if 20+% of the battery was used on IDLING/STANDING BY?
I think I'll try it again tomorrow since I have a longer shift, and thursday since I'm off and see if there's any difference.
The point of this post?
I wanna get even more tips to see if I can get more life out of this battery.
where are the people talking about they get 2 days' battery life out of it?
give me some tips to get to that level!!!
You could use setcpu to underclock the phone. Also maybe you should stop using advanced task killer as many people have mentioned on the board it isn't off any use in froyo it may actually harm battery life. I think the battery indicator may also be a potential battery drainer. You should just install the battery percentage mod.

Get the 3500mah Seidio Battery. You will never have to worry about your battery again.
here you go two websites that have my phone lasting from 7am - 11pm with use

the overclock widget and the settings is highly important I can take my phone off charger and 20-30 minutes later after a few txt messages I still show at 100%. I do turn off my 3g but I do run wifi... Try it out
Some of these people might not agree with, but I’m now pulling over 20 hours (possibly even more, I recharge when I get to around 30% battery) with heavier usage than you, exchange set to “as items arrive”, beautiful widgets set to sync weather every 2 hours, data always on, and no airplane mode at all.
1 – lose the task killer. Let things sit in the background. If the background items aren’t set up to sync, then the amount of cpu and battery they’re using are negligible. You actually might be wasting more battery and cpu trying to keep them killed.
2 – uninstall all stock apps like news, stocks, peep, talk, etc
3 – try the BakedSnack ROM, or at least his Baked1 kernel on your current ROM – his built in underclocking helped me out enormously.
4 – if you’ve flashed a bunch of ROMs lately, you might want to go through the Cyanogen’s battery recalibration process
You might also want to try setting up some SetCPU profiles, I don't think it's needed with BakedSnack, but it works wonders on other roms.
Also, your note about "how much use is someone getting out of a phone if 20+% of the battery was used on IDLING/STANDING BY?" is a bit off - I think your percentages are so low there due to your 5 hours of airplane mode. Can you post your uptime and awake time? That will give you a much clearer picture of usage.
And this part is a personal pet peeve of mine - if almost half of your 12 hours uptime is in airplane mode, that's not something to be proud of. it might be better than what you had before, but people are getting 10+ hours without airplane mode - if you have to cripple your phone to get good battery, that shouldn't count.
I think basically getting your phone to be underclocked when its idle will be the biggest help. The Overclock widget lets you set your processor speed. I am also running stock rooted 2.2 with all the garbage apps removed. I ran mine both ways with wifi and 3g on all day and wifi and 3g on demand. I have gotten very good battery life since adding OC. I agree that you should use your phone as normal and make your decision from there... but underclocking seems to be the way to go

I HAD TO put the phone on airplane mode for the simple fact that my job has a very low signal (I think Kroger INTENTIONALLY blocks cell phone reception because I get a full signal outside, almost no signal inside, and it's like that at EVERY kroger I ever go to!) and if I don't put it in airplane mode, my battery would have drained extremely fast.
I don't have the up time and awake time because I didn't think to do a screen shot of it.

the alternative is keep it off of airplane mode and have my battery die off in 2-2.5 hours. Yeah, I think I made the right choice in that instant lol, usually I don't use airplane mode except when I'm sleep

If you can flash an undervolted kernel, it makes a big difference. No task killer, and I wouldn't go with automatic brightness, it uses too much battery for my taste.
Anyway, I'm on CM6 with Snap kernel 5.01 and just got 22 hours 15 minutes with 30 minutes of phone calls, an hour 15 minutes of BT stereo streaming, approximately 1.4 GB of file downloads overs wi-fi, a good 30 or 40 text messages, and a bit of gaming, emails, web surfing, etc, where the display was on for 4 hours and 11 minutes... I was down to 4% when all done.

Setcpu is probably a little more complicated than Overclock widget, figuring your a noob thats why I suggested that but it has been working great for me. To remove apps you must be rooted and if you are you can use root explorer.

depends on the rom - but titanuim usually works. Just don't uninstall any of the stock weather apps - i've heard those can cause issues if you unistall. Makes sure that they're not set up to sync though.

sort of, it's a bit more advanced, and allows you to set up profiles. There are enough "SetCPU Settings" threads out there, that you shouldn't have too many issues setting up profiles. Again though, depending on the rom/kernel, you may not want to use either.

not quite - it's not just that your phone is doing nothing, those items also show that they're waiting to do something. In arplaine mode they're not even waiting, so the percetages will be much lower. I don't think I'm explaining this well, but by putting your phone in airplane mode, its telling standby and idle to stop being ready, and basically turn off, so of course the total percent will be lower.

That makes perfect sense - what I was really trying to say is that if you're putting the phone in airplane mode for that long, your battery time should be MUCH better.

not sure what you mean here - you can find uptime and awaketime under settings in about phone under battery. was really just curious about the numbers not necessarily a screenshot, although you should be able to a screenshot of any screen if you wanted - try shootme from the market. - edit: just reread what you wrote, I misunderstood what you were saying

so why would u buy an HTC phone (that's gonna come with sense btw) if u don't want it?
the facebook implementation is the greatest.
Im currently on Pinky Desire 1.8, it seems good and stable and everything, but im not sure about the battery life. Feeling hesitant to change to a separate ROM because it probably wont be as stable, and besides, ive practically tried em all.
So im just wondering, is there some kind of inner deper tweak that ROM cookers alter to improve battery life? Or is SETCPU just a magic worker?
well, I dont know what could determin the battery life in a custom ROM, bt SetCPU is really good! just go to profiles, selet screen off, and go right down to 245mHz, really did the trick for me! 3 days of battery with heavy use (3g off when not using the phone)
Hi, the main things that eat the battery are the screen on/off time, it's brightness, wifi, bluetooth, gps, 3g and heavy apps like satnav. You should be alright with most of the roms even if some of them are less battery friendly

sorry, have to correct you on that, The screen does not eat up the battery! 8 - 15% is tiny compared to the massive 80% by Android System! thats why its called Organic Light Emiting Diode.. if you have a SLCD then its even less!!

I am familiar that a 15 quid nokia lasts for a week, we are talking pdas, they all have OS of some sort.
What about this setCPU, I haven't used it, I tought the phone was scaling the cpu by itself. What does it do differently?

The difference is that is forces the phone to use from X to Y CPU, not more. It sets a cap.
Anyway, I don't really believe in SetCPU. My logic says that if for an calculation it needs to run the CPU at 1GHz for 1 second, forcing it to not pass the 250MHz mark will make that calculation run for 4 seconds. So the battery will be spent again for 4 seconds (instead of finishing the job for 1 second and that's it, job done).
Still, that is my logic, not my knowledge

3 days with the fallowing; 3g off, wifi off, bt off, screen brightness medium (auto), auto killer (about 260mb of RAM free), use Advanced task killer widget everytime I'm about to lock the phone, and someimes auto killer, Live wallpaper on (white circles, a clock, but mine is set on "Midnigh" theme), All apps on SD, Turn off internet (hold power button, till a menu comes up, and press the option that is at the bottom, or use a widget, +-> Widgets-> System (?)-> 3g I think, (sorry havn't used the phone in a while ;/)
3 days, gaming, listening to music (headphones), and I'm also running NeoPhyTe 5.3 if that helps (not the battery saver, the normal version
hope this helps! good Luck!
Alright but then why did you got a desire, you use it at 250mhz, no internet, screen dark, if you say you have a spare handset for calls . Point being why would you get a powerful phone and keep it on standby

I use it at 245mhz in screen off profile so its on 1 ghz when using the phone and 245mhz when the screen is off. The screen is normally set on automatic when not watching a movie i last charged the phone on 31st and today it is at 14%.

and it is a smarphone but why do I need internet on while my smarphone is in my pocket?! or when listening to music or playing a game?! I don't need my weather widget to update it self every 5 minutes, because I can just look out the window and see, and also weather does not change that quickly that the app has to change it self (once a day is enough). I do go alot on facebook, internet and sometimes on the XDA app.. I never use my WIFI cos thats why I've got a 1GB data plan, for which I pay extra..
I do play alot, abduction, robo defence etc also, some more demanding games.. asphalt 5 I also sometimes go on utube, and the usual sites you'd go and to check up on the world
So, yeah, not really offline all the time mate
This seems strange.Yesterday after upgrading to gingerbread ( with the RUU because the OTA didn't work for me) I got a huge battery drain.Over the night I got a loose of 40% and now only 3 hours after unplugged and lost 20%.
I only took a few pictures and a phone call.
Only few apps installed since i got this rom since only yesterday.
Anybody experienced this and is there a fix?
Hello,
I can confirm this.
I have also a high battery drain with ALL Android 2.3.* ROMs.
I use the recommend Radio for each ROM and I've checked the RIL to be sure the Radio is correct. But doesn't matter, current in StandBy is between 30 and 50mA.
Only if I turn off WLAN and Mobile Intenet, then I have normal values between 3 and 5mA.
With FroYo I can leave WLAN and Mobile Internet enabled and I had 3-5mA in StandBy
It could not be an application, because I've tried this with a fresh install without Google account to avoid the installation of external apps.

you'd have to edit the build.prop and change the rescan time from 15 seconds to 30, 60, 90 or 120 (or whatever you perfer the rescan intercal to be at)

Try resetting the battery stats by doing the whole charge, lead out, charge, turn off, charge etc. thing.
Also, whilst not a stock RUU I did find it took a few days for the battery drain to calm down a bit. First instal lowest was around 50mA but adfter a fe days it went down to 4-5mA.

Thank you for your help
What does that value do?
Is that the rescan value of WLAN?
The current stays high even if WLAN is off and mobile internet is on.
Only if both are disabled I get a low StandBy current.

Try resetting the battery stats by doing the whole charge, lead out, charge, turn off, charge etc. thing.

Yes I know this, and I've tried this every time I was flashing a ROM (I mean reset the battery stats)
After a few days? How many days do you mean? 2, 3, 4, 5 days?
@both
But why this problem does not exist on froyo?

Varies but on average I find it takes about 3 days to settle to a point where I see a consistent drain.

Unknown. It's not 100% due to GingerBread as I've only seen a handful of people complain of this issue (relatively speaking). I see more people saying how much better their battery life is after the update than saying it's poorer.
Doesn't help I know but makes me believe that this is maybe a Network / Radio issue in that the new Radio with GB does not play well with the Network. We had this a few times on the HTC Hero.
Ok...i have airplane mode on for about 2 days.in those 2 days i almost didn't use the phone and got only a 7% lose.As soon as i used the camera(recorded around 15 min) it got down to 50% .
I will test it tonight widought airplane mode on and see the resoults.Also wifi seems to a lot of battery in comparance to froyo.

I haven't noticed these problems with CM7. I got 2.5-3 hours per 1% of drain in standby using juice defender.
If you are finding that turning off data etc is fixing the problem use juice defender. Even the free version will help a lot as it will stop your phone using data willynilly and instead turn it to a periodic sync. With the paid version you can have it stop all together during certain periods or increase doing certain periods. Aka stoping at night and extra during busy hours at work.
Should be a good fix, though it is only covering up the underlying problem still.
Can't really recommend the app enough. With it my phone only uses data when I tell it to (like opening facebook app) or periodicaly to sync and check emails etc. I do use the paid version though for the extra features.
totally agree. i have been using juice defender for about a week. its been a big help. just bought the ultimate a few min ago. going to start customizing.
sorry that i dont have any data yet to back up my statement. maybe in a future post.

im using Leedroid 3.0.3 and i dont get any such battery drain..
tbh im getting a better battery life from GB than from froyo..
on standby currentwidget shows me between 4-7ma with wifi on... with a peak once in a while..and i lose abt 1 to 1.5% per hour
with wifi off i get about 3-5ma..
i dont use mobile data much so cant really comment on that..
try calibrating your battery and try changing the scan interval in the build.prop... i normally keep it at 90...
i never used any battery saving apps, so cant comment on their performance either...
go to wifi advanced settings and untick Best Wifi Performance... that also helps a lot!
hope you get your problem sorted
Thank you all for the help
The issue was not with gingerbread...I just left my phone one night with wifi turned on and lost 40%.But still when I was on Froyo wifi wouldn't loose so much battery.Now I loose almost 2-3% every 15 min if surfing the web with wifi.
And about changing the scan interval in the build.prop...How can I do that?Do I need root?
I'm also having battery problems, but mine are a little bit different, if I'm on wifi it uses between 3 to 5% with a peak now and then. if wifi is off and I'm on 3g, it's between 5 and 500 ma and you see only peaks if you check currentwidget. anyone a clue? working on ARHD 5.1.6 now, but problem was there since version 3
I have battery problems also, my battery dries after 1 day of use. For example this morning, I unplugged my phone full from the charger at 10 am. I went into town, listened to about 20 minutes of FM radio. When i stopped the radio, I still had 98% left of the battery. OK so far. After, I talked for about 5 minutes, sent 4 messages and played for about 15 minutes. I arrived home at 2 pm with 75% of battery left. That is 25% in 4 hours.
I was on 3G, but with Mobile network off. BT, WIFI, GPS off. A few days ago, I tried running the Battery Calibration app, but seen no improvements so far. My phone is routed, 2.3.3 and has Android Revolution HD 5.0 RC1 ROM .
I expected the battery not to last for long, but this is ridiculous.
Help me, please!
I don't know if that will help, but I sometimes switch to 2G networks as HSDPA is using quite a lot the battery.
I have a DHD running 2.3.3, and it's definitely the mobile standby bit which is first in the battery use screen (33%). It was true before 2.3xx but now it's a bit more - annoying in other words.
I have to admit, having to switch to 2G networks is a bit of a pain in the *ss, so I'll check if juice defender give me some good results tomorrow and will post a feedback there.
Maybe try AR 5.1.6. + he recommended radio. It works wonders. the battery life is improved a lot...
malik
Juice Defender works very well - with basic settings I still have 35-40% of battery by 7pm.
furstrated with the battery life...
hey guys,
so this is my first post and all i've done up until now was to read... i'm afraid not real solution has come up.
i have:
Leedroid 3.1.2 with the recommended radio and i ran the script for Full Wipe 1.5 and cleared the battery stats, i did a fresh install and then didnt restore from backup - just installed everything from scratch. i hoped it would be ok, but when i woke up to check the current widget log, i saw that in the middle of the night he climbed to 150mA and stayed there draining about a 1% of battery in 3-4 minutes (!!!)
what can i do? 'where is my droid power' shows only HTC Sense at about 3.8%
please please help... thanks!
Hi, how its your average batery life?
I have never really run any tests for it, but i've left the tablet alone for a few days, just sometimes checking for Firmware updates, and it barely lost 30% (maybe less, can't recall).
with no live wallpapers on mine lasts a few days with moderate use (checking email, rss, news, maybe playing a couple games)
Well i got the Archos 80 G9 250 gb version and mine lasted for 4.5 hours of continuous video playing , screen brightness on 50 % . The problem is that even in deep sleep it looses battery . How can it last for a couple of days i can't understand , any hint ?
I have the flash version, maybe that would make a difference. Check the wifi sleep policy, and make sure it turns off during sleep. Also, I keep bluetooth and gps off. perhaps try that?
I have the basic 80 g9 and for just using it the evenings it will be happy to last for 4/5 days with email, twitter simple games etc. When I've travelled with it in 3 hours of video playback I lose about 50% with no connections such as WiFi or 3g.

In the meantime you close the tablet or put it on deep sleep ?
I just hit the power button and leave it. Like I say don't think I've messed with the deep slept setting but can look for ya later if you want.
Sent from my R800i using XDA App
Well actually i didn't checked that but i have the impression that mine looses a lot of battery in suspend mode .... I always shut it down and even like this when i start it again its not the same as it was .... maybe the actual starting process uses a lot of power don't know
Could be a rogue app. My phone was like that for ages and it was getjar nit letting the phone sleep properly. Try better battery stats or something similar to see if a service is causing partial or kernel weaklocks too frequently

The 80G9 1.5 GHz turbo I just started using is to new for me to get an idea of run time, so far about 8 hours of mixed use, on my 8gb classic would go between 5.5 to 9 hours depending on use, in deep sleep non use, it would go for days at least
What works for me, on best battery management, I like to put into deep sleep every time I put tablet down and plan not to use for a few minutes or more (this turns of Wi-Fi, screen, and stops mosts things from running) it always wakes up with a quick power press and Wi-Fi connects within a few seconds
I use normal sleep (same as when it times out I think) for quick pauses in use.
normal sleep for when not using but charging if I want to hear notifications for email, Color Note, Evernote etc. (Wi-Fi on)
If I want the quickest charge, (not using, overnight etc.) and I don't care about notifications (Wi-Fi off) I use deep sleep. edit, to be clear on notifications, my Color Note notifications work while in deep sleep
Turn off for longer periods not being charged/ used
You can set when Wi-Fi disconnects by going to:
settings, Wi-Fi, Wi-Fi disconnect policy (I have mine on never for now)
*and of course, use the correct cable and charger!
I have a rooted G2/Desire Z. What are some ways that I could save battery? It seems it takes only a few hours for it to reach 50%. Granted the phone is now >2 years old and the battery is probably aging. I've done all the basics such as screen brightness set to auto, dim after 30 seconds, etc. etc. etc. What more could I do?
Alternatively, are there any apps that can control the phone/cpu to work a certain way to save battery life?
Thanks

Easiest way:
Uninstall fabebook app, flash a sense rom where you can access most fb functions without the app.
For real, my battery life went from about 10% an hour to 4% an hour on average.

Honestly, way number 1 is to get a new battery. Old batteries just start to drain much faster as they get older. Pick up an Evo Design 4G stock battery for a nice boost.
2. Turn brightness off auto and put it as low as you can handle. Keep a brightness slider on your notification bar for those situations you need to turn it up quickly.
3.Turn everything that "syncs" off of push and set it for 1hour+ intervals if possible.
I have had great standby time using the OC daemon that is packaged with the mimicry ROM as well.
There is this trick that helps. On a monthly bases drain the battery and re-charge with the phone on ie also a good Rom an a good radio version like .19 will keep your battery good don't use lots of ram manager apps and bettery saver apps the run backgroung processes that drain your battery fast

With 2 year-old battery there are only 2 options:
1. Replace the battery
2. Buy a new phone

^This (regards to #1), and working batteries are rather cheap, the fat one I got (3500mAh) was 9$, but you can easily get a stock replacement of the 1300-1500 range to fit with the default battery cover.
Far as tips, rooted or not:
1) Screen to automatic, or avoid 'full brightness'. Your screen consumes the most of your battery, automatic or lower brightness can improve the life significantly. This is the big one as your screen will typically be 80-90% of your battery life.
2) If you are near wifi often, System Setting -> Wifi -> Advanced (via menu) -> Sleep profile to always on. This will set it so that the wifi connectivity is always on even with the screen off. A connected good wifi connection uses far less battery than your 2G/3G data constantly searching for a good or better data connectivity. Simply turn off wifi completely when not in an area with wifi (or if you're driving around).
3) Avoid unnecessary applications. Don't use twitter? Freeze/Disable the application under manage app or under Titanium Backup (generally it's not good to 'uninstall' an application completely if it came with the rom).
4) SetCPU with profiles is one way to do it, unless your rom comes with a CPU Daemon already (ie: mimicry with virtuous OC Daemon), When setting a "screen off" profile, try not to go below 768mhz for the maximum, as going with 384mhz for example may be too slow for the phone to effectively wake up when a call or notification comes in.
5) You can use an app such as Tasker (not to be confused with task killer). Where you can assign automatic tasks, such as automatically setting Radio to 2G when connected to wifi (some roms like AOKP do this automatically under power control), or other tasks depending on the circumstances.
6) The first time you get a new battery, make sure you leave it on the charger for a good 5-6 hours so that it accurately 'tops off', the phone won't know accurately what's 100% and what's 0% until it has been fully charged (least 6 hours minimum), and fully drained, after which it'll more accurately report your battery % as it's used and will have more accurate usage stats.
7) If you're a T-Mobile subscriber, consider the 26.13.04.19 radio as well as the T-Mobile Wifi calling app, wifi uses less power in the long run than your radio via cell towers. If you'll be in a location that has wifi often you will benefit from this over not using Wifi Calling. (The main downside is you cannot currently send/receive MMS over wifi calling, but Calls and SMS[txt] work fine). Even if you don't use the wifi calling app, the 26.13.04.19 radio provides better battery life over the older one.

Course it helps to clear battery stats before performing this task so that the OS/Battery-Stats records the new maximum and minimum values of the battery. Though you don't need to do it monthly, I would say closer to 6 months would be appropiate if you don't want to make a monthly habit of it.
You mainly only do this on account of battery aging (over time the battery will not hold as much charge as it once did), You normally know if you need to do this task again if it appears to be on 98% or 99% forever never reaching 100%, meaning that the battery is no longer able to hold the juice to provide the former-maximum mV value, re-doing the battery stats simply makes the new maximum marked as 100%.
PS: Strip419, on an off-topic note, I tend not to 'thank' people who ask/beg for it. If your post is worthy of thanks, they'll be clicked on their own accord.

Best rom I've ever used for battery life is EliteMod. That rom did something crazy, cause my phone lasted for days before it need charging, and I use facebook and all that good stuff. It's not as fast as other roms, but battery life is certainly the best on that rom.
Also yea, before with stock battery my phone would last a day at best, and now I have a 1800 battery that makes it last for 2 days easy. So if your phone is at least 2 years old, get a new battery. They're dirt cheap on Ebay or Amazon. The phone comes with a 1300 stock.
simply change for normal use 2G instead of 3G.
A couple of questions--I'm using EliteMod CM7

My Advanced settings don't look quite like yours, alas. (I'm using EliteMod cm7.) The section is entitled "Wi-Fi sleep policy, Specify when to switch from Wi-Fi to mobile data" and the only options are " When screen turns off," "Never when plugged in," and just plain "Never." I assume that the "Never" option, that is, never switch from Wi-Fi to mobile data, is what you mean...that is in any event the default (set by this particular ROM?)
But my problem goes beyond not quite understanding the semantics of "Never" (off?) vs. "Always on." What I continue to find odd is that my highest battery usages, at least according to Battery Monitor Widget, are never the screen at all; rather they are cell standby, Wi-Fi, phone idle and Android System...Display is down at 6% just now, for example (and I've been up for hours, have read the news on the phone, emailed, texted, etc. This is on EliteMod only, btw, I used Flinny's latest build (.94?) for a few days recently, and while battery usage was worse, at least the display was at the top of the list, where it (presumably?) belonged.
I have all the latest and greatest tweaks from the the forums (for cm7 roms, that is) the .19 radio and sd-ext and all ext4 partitions. Am running the generic 3500mah "fat boy" battery...drained and refilled several times, all according to instructions...mine only shows maybe, umm, 2300 or so mah, but that's not the issue for just now...it's why my usage looks so odd, and how to fix it, if need be.
thanks to all,
p-d
oh yeah. I have long used (pre-rooting) Lookout and Pouzerate's Green Power free apps...have now turned them off (well, uninstalled them, in fact) just to see if, indeed, battery helper apps make things worse, running in the background... any thoughts on that topic would be welcome as well.
