I think Wolfbreak's Gaming ROM is the best I've used so far, it balances battery life and performance well. The pRIMe X ROM had shocking battery life when I used it. The issue is that I use a lot of data, and the pRIMe X ROM didn't do well with battery life but the Gaming ROM seems to be doing way better :)
[XPERIA X10 Q&A, Help & Troubleshooting] laneyofdeath:
Ones to try: wolfbreak, T.E.A.M. Strikes back, fxp 111 cm7 (this is prob best cyanogenmod based Rom), feralab, ewjet and donut hd pretty decent too. If I forgot any then apologies. (not in order of preference just as I remembered them) best bet is try these n decide which suits ur needs best. They all stable though so should do ok woth any of them

Edit: should also point out these are my personal opinion other people may think different
[XPERIA X10 Q&A, Help & Troubleshooting] theunderling:
Ive tried several roms and several kernel combos.Im very happy using Feras v.10.3 rom with dkv.06 kernel.....I would say its provided the best battery life out of all the roms Ive tried,and its fast and smooth.

And in case youve not thought about this :- whatever rom/kernel you choose,you are better reading each ones thread to see what problems and solutions are on offer......and that can be a couple of thousand posts :D

(Feras v.11 the rock has only a couple of hundred posts to read through since he launched it ;))
[Windows Phone 7 Q&A, Help & Troubleshooting] psyco_r:
Hi, I've bought a LG Quantum (C900) from AT&T a few weeks ago, and since I bought it, it keeps rebooting.

When I say rebooting, I mean that it simply restarts, like if I had turned it off and then on again...

It happens a lot, and only when I use non-native apps, like "Ask Ziggy" or "Birthdays".

My phone is not unlocked, but it is SIM-unlocked and I'm using it with a non-AT&T SIM card (I'm from Brazil). I already tried to restore the phone to the default settings via "About" menu on "Settings". The WP7 version is: 7.10.7720.68

Any thoughts about this problem? I didn't find any topic presenting a problem like mine.
[Windows Phone 7 Q&A, Help & Troubleshooting] psyco_r:
Nobody had a problem like this?
[Windows Phone 7 Q&A, Help & Troubleshooting] GoodDayToDie:
It's almost certainly a hardware problem, although you could check and see if there's a stock ROM you can re-flash just in case it has a bad ROM for some reason. My guess is a problem with the storage chip, though.
[Windows Phone 7 Q&A, Help & Troubleshooting] psyco_r:
Can it, by any chance, be happening with apps that are not Mango supported?
[LG Optimus Black] Zaihanzainal:
Hello, I'm starting this thread to actually discuss general battery usage patterns/ concerns. I figure this might be helpful for some people if not then..... =P

currently im using stock gb battery monitor to roughly monitor my battery usage, there is a mod to make the reading more accurate but i havent applied it yet...

Also... lets put up screen of the best battery life we've managed to get our phones here heee, would be fun to see =P

--

question is,

1) is it normal for mobile standby and phone idle to be ard 50% ish?

2) is it normal for my phone to stay in awake mode when i turn on the alarm

On Zeus v3n

Nice idea..

I charge my OB every night, and reboot after alarm in the morning. I dunno if it is from alarm or charging but if I don´t reboot the juice is gone in about 8 h. also battery usage app is frozen. I have this issue on every ROM, ( stock 2.3,CM7 from kang to about 60, marvell, zeus test v2.1, nova v8).

If i do the reboot in the morning the phone uses about 50% of the battery during the day (17 h). i use it for a few sms´s and calls, about an hour of websurf (wifi) and some facebook/ Xda usage..
[LG Optimus Black] re4lsk:
deleted :P
[LG Optimus Black] Zaihanzainal:
I dunno, if in not mistaken, when you reboot it deletes your old battery stats bin but I'm still trying to understand how resetting a stat could make the battery last longer its what most battery calibration apps claim to do...

For me once a week I manually delete the stats thru cwm and yeah it does make the battery seem more resilient.....

And yeah I got the same again as my photo again, phone stays awake when I turn alarm on.... :/
[LG Optimus Black] bayaku:
I did all in my battery, but the maximum is a day and a half!

Depends on the intensity of use.

I'm using Android 2.2.2, v10a
[LG Optimus Black] jason600:
Deleting batterystats.bin does nothing to callibrate your battery. It just stores info, like a logger. BatteryUsage retrieves the info to display it.

Check this link for a more detailed post from a Dianne Hackborn, an Android system developer for Google: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
[LG Optimus Black] Zaihanzainal:
very good info for affirmation! thanks!

ok so calibrating battery after flashing a new rom is for??

and my questions in the op has anyone experienced the same things?..... =P
[LG Optimus Black] jason600:
Something is causing a wakelock, what happened to you is not normal. Usually a reboot solves things like that, if it doesnt, then it will either be a rom bug or an app holding the wakelock. Use Better Battery Stats to find whats causing it.
[LG Optimus Black] Zaihanzainal:
thanks for the app recommendation found that my dialer is causing a portion of my wake lock..... and system too.... hmmmm

ok lets just say my dialer keeping my phone in a wake lock is caused by malware... would a clean install of a rom and manually reinstalling of apps w/o data get rid of the malware?

meanwhile... googling wakelocks =D
[LG Optimus Black] KC Boutiette:
Hi, I have some experience with sudden huge battery drains and wakelocks etc. both on stock V20N and Zeus v3.2n. I did not figure out how/why it works but here are some things you can try. I did not have any huge battery drains anymore the last 24h! (on Zeus v3.2n, did not try on V20N stock)

- I have an IMAP email account installed with K9 mail and an ordinary hotmail account with the hotmail app. Both accounts are set on push and in this configuration the hotmail app causes my wifi to never go to sleep, causing increased battery drain. Removing the hotmail app solves the problem.

- automatic update of time and date settings can cause wakelock. Unchecking Settings > Date & time settings > Automatic might solve your problem. I read this somewhere on XDA.

- Use wireless networks to determine location might cause wakelocks as well. Unchecking Settings > Location & Security > Use wireless networks might solve your problem. Read this somewhere on XDA again.

As I said, I did all of this and my wakelock problem is gone for at least 24h! Now I already have 60h on one battery and still 43% left... I cannot remember the threads where I read about this but if needed I can search... Also I did not try yet whether any single thing actually caused my problem. I just killed all of it as I do not miss it I am happy. Keep me updated if you found out which one worked for you ;)

Tip: the BetterBatteryStats app is written by somebody on the XDA forum, you can download the apk for free from some thread in XDA (search is your friend)
[LG Optimus Black] schurgatzi:
I think a day and a half is a good battery lifetime for the OB, if there is no app or something that drains the battery in a hard way.

I can manage to get this with the marvel rom, and my personal user-settings. Also i think every smartphone u can actually get needs to be charged around every 24 hours.
[LG Optimus Black] yasirshafiq:
I also want to share my experience. I use the cm7 2.3 gb rom and the battery response is very bad. Battery completely dead in 18 hours. Then i switched to v20n german gb rom. It gives me better battery timing about 28 -30 hours on normal use. The i change the settings of account syncronization of gmail, hotmail, facebook etc to manual. Then there is a big difference in battery drainage. Now my battery consumed in 48 hours on normal use.
[LG Optimus Black] yasirshafiq:
On android phones, if yours phone gives u 24 hours backup then it has good battery timing. Further you can increase the timing through the steps and trick mentioned by different peoples in this thread
[LG Optimus Black] aveenhuysen:
Battery should last at least 18 hours on normal usage with 3G and sync with gmail , contacts and calendar. Sometimes you just turn off so many things to just make it home with some battery in it....
[LG Optimus Black] DiederikC:
battery is mainly kernel related...

we need good kernels that all..
[LG Optimus Black] gusthy:
Thank you for the wakelock tips.

It seems that V20o is way better than all the other ROMS concerning battery, without any tweak. Maybe it can be further optimizet with tweaks.

A short comment: it is true that theoretically battery is kernel related issue, but in a real world high battery drain is usually caused by bad apps and other non-kernel related things.
[LG Optimus Black] blackcurse:
using zeus v5.03 lite.

battery drains so much when the screen off. nearly 1 percent in every 2 minutes.

but it is ok when the screen off

[LG Optimus Black] gabwerkz:
800mhz?

10chars
[LG Optimus Black] Zaihanzainal:
yup in zeus script i set it to 1000mhz and in set cpu set it to 800mhz =P

the reason i stagger it as such is.......i dunno if its true but i do this cos when i set it at 800 in the script the definite max it will go up to is 800mhz (as according to info from set cpu app) but when i set it to 1000mhz in zeus script and 800mhz in set cpu it gives my cpu the ability to bump up to 1000mhz only when really needed, while most of the time it stays at max 800(as according to info from set cpu app)

and wth is 10chars???? lololol
[LG Optimus Black] gabwerkz:
10 characters/letters. Cause of the short message, cannot be posted. So we add that to fill it up. :)
[LG Optimus Black] Zaihanzainal:
ahhh okok im dumb.... =P
[LG Optimus Black] jes0411:
Setcpu doesn't work well with zeus overclock. I have it in 1180mhz and setcpu shows it's at 800mhz when at full speed, I installed temp+cpu and it shows the real frequency and it's up to 1180.
[LG Optimus Black] Felsar:
Didn't knew where to post this so... this is "general battery usage" right? :p

I'm now using zeusV6 w/smartass2&noop and last night I left phone with ~20%battery this morning I was surprised to see this:

I'm not complaining at all, I mean it gain like 7%~8% but I wonder what could cause this "charge" I doubt this phone is capable to collect ether from air and transform it to voltage :p

as you can see, when it starts to "charge" is blue bar for "awake" then there is a black space and then another "awake" when it stops "charge"... any thoughts? :D
[LG Optimus Black] re4lsk:
Midiclorians, the force is strong in this one...

[LG Optimus Black] Zaihanzainal:
You are using the 20o base? Cos I think someone else on the Zeus thread also has the same thing.... could it be Samsungs over the air charging going on? Hee
[LG Optimus Black] gabwerkz:
You can't review Zeus V6 with a theme installed. Lots of factors which determines the cause of anomalies. Better be safe... and you can't post that on main thread, otherwise GW02 will be mentioned again.

Read the Zeus V6 thread for the posts about the theme. The GW02 theme may work, but intended for old zeus. If problems arise, I don't wanna be blamed for it, nor read it's the theme's fault.
[LG Optimus Black] Felsar:
yes it's v20o, for all [or almost all] roms I've tried [v20x] there's always [or almost always] a peak that looks like gaining battery, I don't know why maybe is like "if you're using me like this there's xx% left" so when turns off screen is like "ok, now there is xx+%" difference between different readings from different statistics I guess... :confused:

I'm really sorry gabwerkz :( but I wasn't complaining nor blaming at all neither the rom nor your theme...

actually I state it clearly...

I think you should relax and read a bit more carefully dude :p
[LG Optimus Black] gabwerkz:
Nah, it wasn't you bro and I understood clearly about your post. All I'm saying is if you showed that to the main thread of the ROM, they will mention the theme.

SOD, wakelocks, etc, the theme is at at the blaming end.

Better be safe. Use the ROM without the theme for a week. Then tell us the difference.
[LG Optimus Black] Felsar:
I agree about that, we're always in a hurry to customize everything that we don't stop to think it could interfer with "original" stats, so in order to make a state about a rom we need to try it as original as possible such as launcher, theme, apps etc etc etc...

but! your theme looks so nice, I couldn't help myself :p
[LG Optimus Black] Nidakos:
I noticed that when I have WiFi on the battery loose its power very quickly. 1 % every two or three minutes.If I have WiFi off the drop is normal. When I was using Zeus v3 there was not so much power lose.
[LG Optimus Black] Felsar:
you mean you're now using zeusV6? maybe is due to wifi power [or something like that] you can drop it down with zeus scrip...

open terminal then type:

su [hit enter]

zeus [hit enter]

5 [hit enter]

1 [hit enter] after this will show stock or costum value

# [choose new tx power] [hit enter]

0>0>0 [don't remember if is two or three 0s to get out]

exit [hit enter] and you're done :D
[LG Optimus Black] mayank_kapoor:

[LG Optimus Black] Felsar:

[LG Optimus Black] mayank_kapoor:
yes you are right..

had i been using it for games ,media etc the battery would have been drained in a day .(most of us know this though)

1.rooted(gingerbread v20o

2. removed unwanted system apps .

3.2g use only not 3g

4.bare minimum use ,you can even say i barely used the phone .it was mostly just lying on my desk.
[LG Optimus Black] Nidakos:
I have done this but I cannot say that I see great change. I will inform you within the next days. Thanks a lot.
[LG Optimus Black] Zaihanzainal:
Just wondering does cold temperatures affect the phone or its batteries cos I've noticed but don't know if its true that my 3g tends to get stuck and I would have to reboot my phone also my phone reboots by itself more when I'm in my office and the air conditioning there is freezing cold.....
[LG Optimus Black] Felsar:
temperature does affect circuits, the standars for electric/electronic components are meassured at 21°c temp basis

normally at hot temps batt consumption is higher than at cold temps
[LG Optimus Black] Zaihanzainal:
But will cold temps cause it to act weird also?
[LG Optimus Black] Felsar:
how wierd?? I mean, even if tests are made at 21°c, there's a wide temp range for them to work... some places like Russia and Iceland or the kind are always cold wheather and some other places are always warm so they make devices to work on almost all wheathers...

but, a few months back it was winter here and I do noticed that when it was really cold my phone was a lil bit laggy
[LG Optimus Black] verszipo:
You have to remember that batteries (Li-Ion included) don't like cold too much, cold as in close to or under 0 degrees Celsius. They will discharge a lot faster and sometimes they will not give consistent voltage which will make the device (our phone in this case) go berserk.

I know from my DSLR camera that under 0 degrees Celsius the battery will only last half as much (or even less) than at 15-20 degrees.

Google maps causing wakelock & battery drain?

Yesterday I used Google Maps on Wifi with GPS and wireless location off and I think this caused my phone to stay awake (see first pic) with increased battery drain as a consequence. Rebooting solved the problem.

I've had this problem before after using OsmAnd (free offline map app). Back then the GPS was on ofcourse. Again rebooting solved the problem.

I think Google maps causes some wakelock in the LocationManagerService which in turn keeps my OB awake (see second pic).

Does anyone have any idea how to solve this or learn more about how this works? I don't like to not be able to use Google Maps anymore and I don't like to reboot every time after using Maps either. And finding out your phone run out of battery what you did not expect is no fun either ;)

By the way, I am on Zeus v6.11o
[LG Optimus Black] jason600:
There's a lot of info about that in the BetteryBatteyStats thread http://xdaforums.com/showthread.php?t=1179809

The problem is with Latitude, you need to log out of it.

Google maps has always been a resource hogger. I only use in occasionally, so I freeze it when I'm not using it, and unfreeze when I want to use it. As it only takes a couple of seconds to freeze/unfreeze, it's an ideal workaround for me.

BTW, I couldn't see your screenshots, they wouldn't load on my pc or my OB.
[LG Optimus Black] KC Boutiette:
Jason, thanks for the info!

I am going to look at the thread you mentioned.

About the screenshots, it is weird but I cannot see them either. I uploaded them though... Hmmm, have to try again.

Edit:

Ok, just researched it a bit and I finally know what latitude is ;) But as I did not use that before, it is not my problem. At least now I know. Now lets explore the freeze/thawing of Google Maps.

i've bought a 3600mah battery from hong kong (about 8$, ship included) and antutu score is about 650 (with stock battery is 382, i'm using nova v8 rom, 1100hz)

[LG Optimus Black] TheGripper:
This is my battery life with zeus v6.11n. I had almost no time to use my phone, I only checked mail, some web browsing and xda ;). I was super busy with work. And it actually surprised me, didn't think it could last this long. I think it could last over a week with no use since now the screen was on for over 2 hours.

[LG Optimus Black] ronie_123:
Installed Zeus v6.22 after gingerbread v20b and now the general battery life has increased but standby time has decreased . Earlier when phone was 100% charged and left overnight , next day in the morning it would be around 97% remaining but now it says 94-95% .

Also after installing Zeus games have seemed to lag more eg fifa 12 , GTA 3 etc , did i do something wrong ?
[LG Optimus Black] xKyrex:
Is it normal to the battery only lasts one day?
[LG Optimus Black] Zaihanzainal:
If you have 3g always on and check web stuff every few mins like me I guess it is...... I get about 24-30 hours including 7hrs sleep.... also I rarely get full reception at the places where I'm dormant.....

Hi out there .. is there a good .. , i call it tutorial for now, for better battery stats?

I think it will take me weeks to figure out every option :(
[LG Optimus Black] :
I found the biggest battery drainer to be any type of sync whatsoever. It wakes up the phone for prolonged times when the screen is off.
[LG Optimus Black] aniym:
Using Zeus 6.20 with Battery Calibrator app. Currently still waiting for it to run down to zero after leaving it unplugged for the night while I slept, and after using it for 2.5 hours of 3g/wifi and music. Very pleased so far. Hope after the recharge, it maintains this kind of consistency. Though right now I have only Gmail and Whatsapp syncing...normally I would also have FB messenger.

Before was running stock 2.3.4, which had absolutely horrible battery life, literally 7-8 hours with maybe one hour of 3G usage and music, email sync and screen off the rest of the time. Also, the phone would get very hot on 3G surfing after about an hour. And these were not intensive sites, generally mobile version of sites (since I have a limited data plan).
[LG Optimus Black] Mr.Scrooby:
Hey there,

I did a little experiment with my optimus black to see how long would battery last with minimum use. About my config:

I'm on Zeus 6.22 with JuiceDefender Ultimate. I configured a lot with JuiceDefender e.g. nightmode which automatically switches to airplane mode, sync is handled by JuiceDefender every 2 hours, wlan only, only 2G, auto display brightness (power saving). I did some calls and wrote some messages (normal and whatsapp), didn't play any game.

So far so good. The result was amazing: I was on battery for 6 days and had about 16% battery left!!! Look at the screen capture.
[LG Optimus Black] Zaihanzainal:
Damn.... 6days!! :eek:

That has got to be a new record! Amazing!

search button..... just do it.....
[LG Optimus Black] vinziboy:
pretty good... how about gaming? how many hours will it get? :D
[LG Optimus Black] Mr.Scrooby:
It will be the same as on other roms. If phone cpu and gpu is used extensively and battery capacity remain the same and display is turned on you will not see any difference. The thing I did here was to optimize the standbytime.
[LG Optimus Black] vinziboy:
well as of now... i'm still using stock rom V20B... i was planning to root it and instaLL custom rom... i used to play everyday... 3-4 hours is the maximum batt. drainage on gaming... if i use custom rom, will it be the same? i mean the draining of battery? :confused:
[LG Optimus Black] NLDViane:
i think the battery consumption will decrease when you install a custom rom, because of the other kernels and programs which stay on at the stock rom while you lock your phone. With stock LG roms i used to have battery from 7:00 till 18:00, at school, using wifi for half of the time, 4 hours of twittering and facebooking, an hour of gaming, and half an hour of music.

Anyone can help?

Never found the real source that is causing my problem but ever since a few days I do not have wifi always on. This does not solve my problem completely, but makes it way more rare. Well I guess I am just going to be happy with that.
