Let's see how long this puppy can go without charging.
I'll keep its usage only to phone calls and messaging (which is a lot). It'll be my main phone obviously (and I can't turn it off).
Settings:
a) devoid. rom (link)
b) wifi, gps, 3g, mobile data - off
c) brightness @ minimum
d) auto-sync - off
e) underclocked & undervolted @ 480Mhz (min: 122Mhz)
f) governor set to conservative (still thinking about it)
g) hardware acceleration - off
h) watchdog lite installed (to check for apps gone berserk)
i) load monitor installed (to check for kernel loops and wakelocks)
j) airplane mode when sleeping or at classes, exams or hospital
k) red colored wallpaper (red is in the lower spectrum of visible light EM: higher wavelength, lower frequency, lower energy, lower battery consumption?)
Did I forgot anything?
unplugged
03h30m GMT+0, 12/01/2011
99% battery left
How about the Screen Filter???

It's worth to use it also??

You really DO get bored!
You don't seem to have forgotten anything. I don't know if a red wallpaper really helps, since the big consumer is the backlight which you already minimized.
Good luck, I'll be checking this thread to see your record and I hope you are keeping track of how much talk time you get during this experiment.
What about ringtones? Are they on ?

i just did it to my phone.. but with the original stock lg rom. i set all settings to default , no wifi, no gps.... just calls and messages and a little use of mp3's about 1 hour.
the battery is 1%
and i have done 3 days and 2 hours.
1.31 hours of phone calls.
just when i need it..
i had unchecked all sychronization things, apps and i set it to gprs..
without turning off or airplane mode
the brightness was the default.
i thing it can be last longer..

Hmm, well the brightness is already so low :x
Anyway, I have to restart the test.
Underclock and undervolt seems to consume more battery...
I'll unplug @ midnight of 13/01/2011, GMT+0.
Keep us posted.
I've made a Test with Javali, using the LG P500 just for Calls and SMS, and after 48 Hours i still got 60% of Battery.
14 hours ~ 94% battery, without underclock/undervolt or using airplane mode.
i had cpu tuner and it respond so freaking slow...i wanted to save battery but instead ive managed to drain it more faster....

@Noejn: is the test still going on?
this is very interesting !!! all the best Optimus !!
Check my signature
it lasted me 4 days and I had 35% left. I had to do some testing then and had to connect to pc.

Intresting results, not bad for a smarphone! How would you rate your device responsivness do, was it realy sluggish since you undercloaked it?

I didn't underclock it.
I did at first but consumption was higher so I put it back to 600Mhz and restarted the test.
So, by extrapolation, we can assume around 6 days of battery life. Still, without knowing the talktime this is inconclusive.
@Noejn
What about undervolting keeping the same Mhz, is that possible?
@
I never tryed draining compleatly my battery because i keep on pluggin it in my computer to test stuff, but I would be happy if my phone could last aprox. 4days.
@noejn
I read in this forum that you don't have a lgp500. Then how come you are testing its battery and other things.

I'm a long time lurker, first time poster, so please...go easy on me as I'm still trying to figure out the lingo and what not!
Anyhow, I just recently installed V6 and everything is absolutely great - except my battery goes down faster than <insert whatever reference you want here..hockey goalie, boxing, sexual>
I initially tried flashing over V5 and that's when the issue started - V5 was fine the way it was, but was starting to eat up the battery a little quicker - maybe due to a couple of new apps installed? did a full wipe and reinstalled v6 and am experiencing the same issue
I don't know if it's a problem with my actual battery or what...anyone have any suggestions?
Fully charge the battery until the green charged light goes off then reboot into XRecovery and wipe your battery stats.

Alternatively, there's the battery calibration app.
Alternatively, build your own stock ROM. Wolfs ROM has IMHO too many uneccesary tweaks that drain the battery... although his performance ROM has awesome battery (I'm using it right now)... lol I dunno why..

Well its tough to explain u, but use set cpu and reduce the maximum processing speed to 384. The battery will be consumed to the lowest. I have done the same. And my x10 works for min 1.5 day.

um..I have no-frills cpu - figure it's the same, or is set cpu a better app?
max clock freq is at 998Mhz; min at 245; governor is at ondemand (gotta read up on this..) and i/o scheduler is on deadline..should I change any of the other stuff?
thanks!
I use juce defender plus and if needed I could go a couple of days without charging.

Not sure if my problem is the same but my phone WB v6 (even on v5) will turn off when used heavily i guess (less than 5min video games seem to be ok but other apps will do it randomly). but the battery will say like 65% whatever it should be from the use so far after a reboot most of the time i have then same % as before the umm crash but sometimes it shows 25% and turns off then if i leave it for a bet i get back to the higher % but will still crash with a little app use. Frustrating as i LOVE the ROM!
So far no crash during phone calls. But the crashes are no rhyme or reason. I have tried calibrating and full flash but it came back.
(would have posted in the ROM thread but i have too few postes and this seemed a better place)
Hung Wei Lo: which version are you using? Try lowering min frequency, adjust settings (like brightness). I'm on v6 with Freekernel and I get 2-3 days on a full charge. Maybe an app is preventing your phone from entering deep sleep.
Rabbit Stew: are you overclocking? Try a full wipe including battery stats, then installing v6s. The stock version should be the most stable.
Here's two methods that work for me.
To me the battery calibration app, is USELESS, no offence to the developer.
1. Wiping battery stats: http://forum.xda-developers.com/showthread.php?t=943626
or
2. Optimizing battery with just a charger and phone: http://forum.xda-developers.com/showthread.php?t=1071885
Don't go anymore then 5 tries.
I figured I'd give an update on this..
Things had magically sorted themselves out - battery life got better and better each day, though not to the point most of you are getting (I'm talking MAYBE 14 hours of minimal usage - the odd facebook check, random text message etc)
As suggested, I've set the min. frequency to the lowest possible, screen timeout is at like 30 seconds
As of the past couple of days, I've been getting half that...no new apps installed all the same settings...wifi is off, brightness is set to 25%, no gps usage all I have on is data. As an example, I charged her up and unplugged it with an hour to go before I was done at work. an hour ride on the subway doing nothing but listening to some tunes, and I'm down to 60%...in two hours
I'm at wits end here...according to cpu spy here are my most recent stats:
998 - 0:01:49 - 35%
576 - 0:00:-4 - 1%
384 - 0:00:03 - 3%
245 - 0:00:52 - 17%
deep sleep - 0:02:11 - 42%
thoughts (related to this issue)? suggestions? ideas?
is calibrating the battery will solve the phone randomly restart??
In my infinite wisdom, I'd have to seriously doubt it...did you do a fresh install?
Hey, so I've seen several people claiming fantastic battery life, etc. So, I am just wondering what's your experience in general. If you've got some free time and feel like typing, can you list several things like:
roms & kernel
stock/anker battery
battery life
screen time (and possibly voice call time or whatever else that seems to consume lots of the battery life)
highest battery temperature (I recently got pretty high so I was kind of worried)
and anything else you think might worth sharing (favorite actress? :silly
As for me, I recently installed Speed ROM 6.5 with stock kernel on stock battery
I only got 8 hours battery life to get to 14% with 3 hours of screen time (mostly used for game, browsing, and flipboard)
I got up to 100F (~40.5C) after playing a game for about 15-20 mins which made me leave it for a few mins to cool down. The next time I played the game again, it got up to 109F (~43.5C) after playing for 20-30 mins....
I am wondering whether that kind of high temperature is normal or not, and whether my battery life seems ok or bad; which is why I am hoping people can share their experience here. I haven't try using faux kernel though (might try it tomorrow in hope for a better batter life)....
So, again... if anyone got free time and feel like typing, please share it with me :angel:
From my g2 to this phone all I ever see is how bad the battery is. Never noticed a difference switching roms and battery across all smartphones I've used is allot what I expect.
Some people just can't be happy you know. Not to mention people never agree on anything (me included ).
Just my two cents

Well, first off, I am not trying to complain about the phone here. All I am asking/trying to find out is whether my experience is "normal" or not for Amaze.
I also come from G2 and obviously the battery life will be worse on the Amaze in general. This phone is 1.5ghz dual core and 4.3" display compared to 800mhz single core and 3.7" display on g2 with only extra ~300mah on the amaze.
I just want to know if my experience of getting only 8 hours battery life (with 3 hours of screen time consist of game and browsing) and getting a high temperature of 109F on the battery is considered "normal" or not for this particular phone. I only have one phone here; so, I don't know if my unit is bad unit or if it is normal for the Amaze.
So again, by all means, I am not trying to complain about this amazing phone here. I am just trying to find out if this is what normally happen with this phone.
And yeah I'm one of those guys that can never be happy :silly:. When I used G2, I want larger phone and faster performance. When I got Amaze, I want slightly larger screen and much better battery performance. So, yeah I can never be happy with my phone :laugh:
The temperature thing is definately normal, it can get pretty high. I've had it go above 109f while on video chats on Skype. As for thebattery, that's normal too its just dependent on the user. U may have something that's running continuously in the background that your not aware of that's causing drainage. Many things that could be effecting the battery really

@OP, most likely you either have a bad battery, or your phone isn't sleeping properly on idle, or your phone has some problems with the RUU
Code:
Battery is ~1900mAh. If you use it for 3 hours active at around 400mAh, that is 1200mAh
700mAh left for idling the rest of the 5 hours. My idle current usage is around 9-40mAh as reported by Battery Monitor Widget(go to settings, change monitoring mAh to HTC Sensation to get a better reading)
700/5 = 120mAh/hour.... this means your phone isn't sleeping properly
Get CPU Spy... install it, then put your phone down for an hour without using it.... after that, does the report show that it goes to deep sleep?
When I got my phone and flashed the ENERGY rom, I had ~8 hours of total uptime (1-2 hours of usage)... i reflashed the RUU (do it on 100% battery), then it is better now
Now, on the Energy STOCK ICS rom with FAUX latest(0.12?)
Anker battery
15 hours of uptime
1-2 hours of screen-on time(roughly 2-3 hours of phone "awake" time)
don't remember battery temps, but i don't ever remember ti being that high
interactive governor, max frequency 1.4 ghz(to maximize battery life)
data on, autosync on, 2 gmail accounts synced only
My 100%->80% battery drains in 90 minutes, but after that, it slows down
I added the following to build.prop to tweak more battery life
Code:
# Power Save Tweaks
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
If you really want to stretch out the battery, change the governor to powersave(forces processor to 192mhz always), but it definitely lags and I wouldn't recommend it unless you really really need to max battery life
EDIT: Go to Settings->power->see what is using my battery, post a screenshot (this one is 16 hours plus ~2 hours usage)
see the part that says "awake", and the part that says "screen on"? It should be correlate mostly -> when you use your phone's screen, the phone is awake.... when you turn off the screen, the device should be sleeping and not be awake

I guess this phone is just that "hot" eh....
So, you're saying that I should be able to get a better battery life than that?
By the way, did you use Juice Defender or anything like that? Or did you just let your mobile network and wifi on all the time?

Hmm... I would try to check the stuff that you said. I did see the battery use like you did and I have much more awake (since I used it for games and browsing continuosly). But, when I was not using it, it doesn't show that many "awake" status which is why I thought that Amaze battery performance is just that poor. I forgot to try third party app like battery current widget or cpu spy. I will check those out.
Did you use Juice defender or anything like that? Or, did you just set them manually when you need it?
And I did leave my WiFi and auto sync on.... From your usage, I'd assume you turn off your WiFi when you're not using it, right?
Thanks for the input
Edit: So, I am guessing there's a rogue app on my phone? I just reboot my phone, leave it for a minute, and battery current widget shows 200mA on my notification bar
From what I'm reading your a heavy user. Like me lol. The most I get is 6-8 hrs. With 1.5-2 hrs screen on time. Comparing that with others who get double digits It's nothing but I'm a heavy user. I stream Pandora daily surf the internet for 1 hr non stop, xda for most of the time. . And on weekends I'll have most 4 hrs. But 3.5 of those screen on with data streaming and screen on with out going off. Kinda like watching a netflix movie on mobile network. I use my phone like if it is my laptop now. I rarely use my laptop. I don't have internet nor WiFi to connect to. But if I tether I would run out of data faster so I avoid it. Besides battery draining faster.
I think there is a difference between:
1. leaving the screen on for a while, causing the phone and battery to get hot. Specially when gaming because CPU is constantly running.
2. And total screen on time accumulated of 2-4 hrs screen on. Which is achieved when sporadically checking phone for text, calls, email, quick surfing. Then shutting of screen through out the day.CPU goes to deep sleep phone stays cool.
Now that's what I call a heavy user.
Remember when phone is hot battery drains faster so you need to find a way to cool it down. Sometimes there are settings in cpu apps that when phone reaches certain temperature that app will force cpu clock down a lot as to use less power to start cooling down but causing lag.
I've got a 4 month old stock battery with latest faux kernel v.16 with battery saving tweaks on it. Energy rom stock 8-1. If there is anybody that reaches double digits with 6-7 hours 4g mobile streaming not wifi at all. 2 hrs without turning the screen off not 2 total hours. Please say I? I'd really like to know your secret.

Battery Current Widget... go to the options (top right), change the current selection(should be first row, then middle row) to "HTC Sensation" (it'll be more accurate)
that program doesn't accurately report mA if you don't change it(before changing, it'll be screen-off deep sleep 100mAh, but after switching, 10-40mAh)
I don't have Juice Defender on... autosync and data is on all the time
try w/o wifi on... i think wifi should take less battery power than data, but it always depends
on my screenshot, if you go back one and click on the screen-on... what does it say?
what does CPU Spy say about your phone going to deep sleep?

if you are only getting 8 hours uptime with 1-2 hours of usage, then your phone's not going to sleep properly... I'd reflash the RUU, then flash Energy ROM and faux kernel... i had that problem before I reflashed RUU (but that was before I knew more about CPU states and mAh usage on this phone, so I don't know if it was a problem with the deep sleep, or the phone not properly updated to ICS when I got it from someone else)
you want to try to max battery life? I can give you hints to hit that mark... it's all about physics/electronics
your battery is 1900mAh.... Using Battery Monitor Widget(with the Settings changed to detect the phone as "HTC Sensation", see above)
With the tweaks in my first post of the build.prop, BMW shows my idle around 10-40mAh..... 10 hours of idle = 100-400mAh. Note, this is with sync and data on... if you use Juice Defender or data off, probably less
So, idle, you use up 400mAh... you have 1500mAh left
1500mAh / 6 hours = 250mAh each hour.... with BWM, it shows that the current usage goes between 100-500mAh depending on how much screen brightness, data used, processor speed... If i choose powersave, I think it goes between 50-300mAh, but its really laggy, noticeable
300mAh * 6 hours = 1800... close enough
to avoid the 100%->90% fast drain, employ bump charging:
either
1) charge your phone to 100%. remove plug, wait for it to drop to 90%. replug it, charge to 100%... repeat for 5-10 times
2) charge your phone to 100%. remove plug, shutdown. Replug it, wait till the light goes green, boot up, charge to 100%, remove plug and shutdown, replug it , wait till light goes green etc.... do the cycle for 5-10 times
I was trying to see how much I could get out of my phone. I used my phone as little as I could, putting it into airplane mode when I slept.
ROM and Kernel: I was using the latest build of Energy and Faux Kernel v.15 at the time of the picture
Using stock battery, unfortunately I do not know what the highest battery temperature is.

unfortunately, for this device, the screen brightness and dual-cpu takes up a lot of power... if you see the pic below, when you use your phone(screen-on/awake), the battery % left has a sharp drop
I know for my old phone, LG Optimus T, I didn't have a data plan... the phone had data off all the time, and I got days out of using it(phone calls, wifi/browsing, checking gmaps offline)... once I enabled a data plan, it got half (like 1.5 days instead of 4)
if you calculate your usage... its possible
24 hours * 50mAh during idle = 1200 mAh
2 hours * 300mAh/hour during screen-on usage = 600mAh
total = 1800mAh, the capacity of your battery

So if I use either of those 2 methods above, is my battery 'cured" of the 100% to 90% fast drain? Or do I have to keep doing it over a period of time?

bump charging only helps you for that one time... you have to do this every time if you want max battery capacity
the problem is 2 things
1) the hardware/software is configured to maximize battery lifespan, meaning to slowly charge it and not go to 100% (high voltage, damages battery)...
2) the hardware/software is poorly coded, can't read the battery voltage properly...
either way, doing this means you are forcing current into the battery every time... your battery will hold less charge in a few months if you force it to full everytime... so you have to get a new battery aftera couple of months or live with lower capacity
I will just try to observe it better tomorrow using all those apps. With much less usage (1.5 hrs of screen time), i only got 11hrs of battery life. The screenshot below is for those 1.5hrs f screen time... I dont use jd and got email sync every 1 or 2 hr though....
Sent from my HTC_Amaze_4G using xda app-developers app
I tested the idle-deep sleep capacity of the phone...
got 21 hours idle, 17 minutes screen-on (minimal use of phone) with 50% left
here is my phone with data and auto-sync ON, I got roughly 10 emails(all received during different times), had about 10 minutes of phone calls
NOTE: around the first part of the graph, you see the %-left spike up... I rebooted my phone then... and you can see that the battery-monitoring software/hardware part recalibrates itself to the real value
NOTE: cell standby-time of 21 hours used more battery than screen-on of 17 minutes.
When I used the phone for another 15 minutes, screen used 35% of battery while cellular standby dropped to 22%
tl;dr, using the phone, especially the screen, kills the battery a lot more... not using the phone = lasts a long time

I tested the idle-deep sleep capacity of the phone...
got 21 hours idle, 17 minutes screen-on (minimal use of phone) with 50% left

I guess after using all those apps that you mention, I can kind of see that Amaze battery is just way worse than my G2. I was pampered with my G2 battery life for a week and now I realized how bad Amaze battery is. lol
I got 11% left after 12h 15min. That's about 1550mA used (I use stock battery).
almost 3 hours of screen time (3*350) = about 1050mA
25 mins of phone call = ~120 mA
about 8h 45 mins of idle = 360mA
So, yeah, it summed up about right this time (more accurate compared to my first result where I think I got a rogue app)...
**I am eagerly patiently excitedly waiting for a fully working stable CM9 by sport :angel: **
On a side note, just wondering if anyone know if galaxy s2 have better, worse, or about same battery life? I am just curious since s2 is supposed to be amaze rival at t-mob....
Here's mine
Rom: Fourth Bar Jellybean Fusion
Kernel: Faux's Kernel, latest edition [August 15th]
Average Temp: high 90's
Average Battery Life: 5-6 hours.
Realize that what you do with screen on makes a significant difference- If I play organ trail(awesome zombie game styled after old school oregon trail game) I can play for a long time with little battery drain.. but it is a 2d game, and not going to be very processor intensive. If I play final fantasy 3, a 3d game, wow.. battery will drain much quicker, but then again, it IS a 3d game, and processor intensive. So HOW you use your phone is even more important than the screen on time.
With the latest faux(17) kernel, and 2-3 hours of screen on, the last few days I have 45% battery left after 15 hours since unplugged. Maybe 30-45 minutes was organ trail, but not much other gaming. The only changes I made, were made to the kernel, which I posted here(be aware that making all those changes will create some small lag changing screen orientation or opening app drawer, but haven't noticed anything else). http://forum.xda-developers.com/showpost.php?p=30298629&postcount=4
I also underclock to 1.2ghz- this doesn't create any lag, and no game or app I have used seems to work ANY better @1.5ghz than it does @1.2ghz. The main difference is the voltage it uses at max speed will be less @1.2ghz.
If you have weak 4g signal, there is an app i recently posted in some thread that puts it on 2g while screen off.. that has helped a lot too. If you have constantly good signal, then it won't make MUCH difference(tho 2g does drain less than 4g even with good signal), but it takes up to 2 seconds for it to switch to 4g after screen on. I can wait two seconds before opening an app, I don't care.
I assume you have used betterbatterystats to see what apps keep your phone from deep sleep, under partial wakelock?
And when I get obnoxious drain, but NOT because the phone isn't going into deep sleep.. I turn on the logging of an app called currentwidget- it can actually measure the MAH used while using specific apps.. the app itself can cause a bit of drain, but you'd only use it long enough to see what app is so battery inefficient. I have more about how to use that under battery savings part of the bible in my signature.
Edit: And I consistently get battery temperature of 77.7-77.9F, I always have, no matter the kernel or rom or settings.. perhaps it raises a TINY bit when I play some intensive game, but never noticeable. I am using an anker battery tho, so if you are using stock, perhaps that is a factor.

Whoa... I suppose there is someone out there with similar condition with mine... I almost thought I am the only one

Good to know that. I used a different app to check the current mah and it seems reasonable. I forgot to use better battery stat; but, based on cpu spy, the deep sleep time seems about right... I haven't updated my kernel to v17 (still on v15) and haven't done any edit that you mention since I was still switching roms to find the ROM that suits my need. I might try to do those stuffs today and hope for the best.
And btw, I am kinda jealous with your battery life... 45% left after 15 hours unplugged and 3 hours screen ON
I might get similar result; but my battery left will be 10% and those screen on are mostly on flipboard, xda, and browsing....
Like right now, 6h 10min unplugged, 40 mins of screen on (xda & flipboard), and I am down to 66% :crying:
**On a side note, I just get my hand on gs2 and I am just curious to try and see how good it is since gs2 seems to be such a hyped up device compared to amaze.... :laugh:

Just checked my usage. I'm sorta similar to yours in terms of screen on time. 11 h 43 m since unplugged, 39 min screen on (facebook, news, texts) and I'm down to 62%. My screen on time isnt that high, yet something else is draining my battery.
Awake time is 1 h 44m. Lots of Alarm Manager partial wakelocks. need to figure out what's causing those
Post your battery life here and say witch L9 you have. And give the most details if you can
(I will get this phone next week want to see what you guys get out of this phone)
And i didnt see any thread like this. So i start one.
PEOPLE plz post also screen on time!!
edit have the phone. and it has good battery life will post mine soon also.
Battery life is very good, this includes mainly internet browsing with wi-fi and 1-1.5 hours of gaming, brightness always at 50%.
My cpu is undervolted a lot, for example I give only 860mv for 1000mhz, hotplug governor. I have 25% battery left so I could have about 4:30 hours of screen on time using the full battery charge.

Thx undervolt and its stable? Because i have th lg o2x and if in undervolt -25mv its okay but 50 its hangs every hour.
Not bad at all heavy 3d gaming i see. Dark night rises and spider man.
Ow and with 3g on or not? Also interested to see the 3g battery life.

I made massive overclock but it's perfectly stable for 7 days, here more about my settings:
http://forum.xda-developers.com/showpost.php?p=37100010&postcount=16
Unfortunately I have not a 3g plan but I think it should also be good because L9 has a very efficient modem (talk time is one of the best, see gsmarena battery tests).

P769 battery life
I do not have a screenshot, but I have nearly gone 72 hours on one charge. I am using a rooted P769 v10g with most of the bloatware frozen. Wi-if, auto sync, and screen brightness at 50% during that time.

thats really great. 72 hours is amazing. Do you use phone for calling and other features it comes with?

Lol. Granted it was a very inactive time for my phone. I just thought that it was pretty amazing for the phone to make it that long before needing another charge. On average I only have to charge the phone every other day.
Re: Post your Battery Life. With screen shot if posible
This is about average for me. Sometimes as much as three days, but never less than 30 hours.
Sent from my LG-P769 using xda app-developers app
seldom use my phone
Without screen on time other stats are unuseful.
plz people
carter07 is right forgot to say, post screen on time (so we can see if you used your phone alot or not.)
thanksss

your guys battery sounds great;
mine only lasts bit more than one day
For some reason, my battery life has gotten worse than when the image was taken. I am insane, mental, and deranged about battery life so I will have more specific percentages soon. I have tried ending anything I suspected was using the battery to save battery life. When the phone is charging, I even take the back cover off my phone to disperse the heat from the battery. Welcome to the most useless and pathetic obsession in existence.
As you can see, the screen takes up the vast majority of battery life, due to being at 50% brightness. Any lower, and I would have to bring my own flashlight. I turn off wireless unless I use the Internet. One charge ranges from 3 to 5 days, depending on how bored I am in school and how much Fruit Ninja/Temple Run I play.
Here I am again with more battery life measurements. Playing Fruit Ninja causes the battery to drain 1% every 3 minutes or so. On the other hand, leaving the phone on sleep mode causes 1% to drain in about 5 hours. Also attached are app percentage power usages to give a sense of what is using up all the battery.

These are my results with above average use(wifi or 3g always on,sync every hour,a little bit of subway surf...)
5h ?? what brightness u were using ?? 30% ? this is cool
How can your battery last so long?? Mine has never lasted more than one day, never!
The screen is always on 50% brightness,except when battery goes under 20 then i set it to 25 %... The screen on is never under 4 h... With heavy use,battery holds through the day easy... I'm very satisfied with the battery life of my L9..
