Battery Life / Recharge Time?

I recharged my phone in an hour when it had just powered off by itself for being too low... I used it for like 5 minutes and it was already down to 80%... Bad battery?

Sure sounds like a bad battery.
Just to make sure...
1) make sure you don't have some app that is running GPS
2) If not needed, try turning off BlueTooth
Those two items will drain battery faster than usual.

I sometimes find the battery is really inaccurate, depends on if the phone's running hot or whatnot...
Also you might want to get a task manager and periodically close all the apps (some apps have a one-click kill all widget), and turn off syncing, gps, and bluetooth

Battery indicator hasn't always been accurate or me - even with a brand new battery

There are several apps/widgets that are poorly coded which cause high battery drain as well.
Try only using stock widgets as well, I find that helps alot.

Yea, the only Widget I run thats not stock is Beautiful Widgets Home Small, set to update every 2 hours.
I have bluetooth and GPS off always unless I'm actively using them. I just seemed strange it was so fast to recharge mainly.
I've noticed the battery capacity jumps up and down depending on what you are doing. For example if I disable 3G, it jumps up, if I enable it, it might jump down 10% briefly then go back to where it was...
Very strange.

Also, I find the app Juice Defender (free version) is a life saver. My battery life has gone from around 12 hours to > 2 days since using it.
What it does is disable your 3G AP and only enables it every X minutes for Y minutes.. I think the default is 15/2. The result is you still get your notifications (a few mins behind), but your battery lasts WAAAYYYY longer.

Thanks for the tip!
Now going hunting for "Juice Defender".

yeah, juice defender is great. The free version has limited options but the default options really save battery life on my vogue.
I read a while ago that there was a problem with the stock text messaging app. Is that resolved? I use Handcent SMS, but i don't know if it is good or bad for battery life comparatively.

JuiceDefender is fantastic, it works. Except you can't be listening to anything and have it running (music, podcasts, etc...) because when it kills the 3G connection the audio stops. I've talked with dzo and looked at the code myself and I don't see a way to keep it from happening unless there's a way to kill the 3G connection without issuing an 'ATH' to the modem or somehow ignoring the 'No Carrier' message that follows it...

this happens no matter what music player you are using? I was hoping it was just Cube, but had not gotten a chance to try with other media players. Is there a way to create an ap that autodiables jucedefender when you play music?

Not that I'm away of... I just manually disable juicedefender before I start playing my music... and HOPE that I remember to turn it back on...

I am not endorsing this battery/seller/etc or that this is the battery to buy in any way. Just came across this opportunity and wanted to put it out there for anyone that wanted to check it out:

Samsung Galaxy S Battery Drain

Hi,
im having battery drain problems the phone wont last more than 5-6 hours send 20-30 texts listen to some music, i have turned off backgroud data and live wallpapers, im using something called advanced task killer free to kill the apps that are running, but i close them the re open the task bar and stuff like music player has reopened
ive also seen a post about which batterys are better is there a better one i can buy? my batterys a G7
any ideas ?
cheers

Stop using the task kiler and you'll probably see better battery life. Task killers have been proven more harmful than helpful on the newer versions of android so using it is pointless. Also pay attention to what you have synced and how often. tons of web apps synching will drain the battery faster, as will having the gps and wifi turned on--if you're not using them, disable them.

thanks for the reply i will remove the task manager,
auto sync is turned off and i only use email by refreshing the inbox

Come here: http://forum.xda-developers.com/showthread.php?t=884816
In short: Have you recently updated via Kies to JPY version? If so, stop using your wifi. There is a bug with wifi with this newest firmware.

hi,
i update to 2.2.1 through kies

Do you use wifi?
If yes, switch to data, battery life will be better. You should be able to get around 48h of light active usage (i mean browsing and calling and what not) with 3g data on.

i dont really use the wifi, signals really good around me, i only got the phone friday, brought it of a friend,
charged the phone fully before i went out last night about 7pm by 1.30am the phone had cut off, that was only using the facebook andriod app and sending text messages.

Than there is something terribly wrong. Do a wipe and factory reset, if you didnt after getting a device from your friend.. It seems that some application misbehaves and drains battery.
You can check it by typing *#*#info#*#* in dialer
Several options there, if there is something strange you will see it. (suggest looking into Battery history, usage statistics)

i dont know how to type in dialer sorry sounds very stupid all i have are digits

From the above post:
TechnicR said:
About my battery life:
Previously I was on Darky's v5, with that the phone lasted 2-3 days with normal usage.
After flashing to v7 (with 100% battery) I also got the fast drainage problem. Here is what I did:
1) Turn OFF phone
2) Charge till it says it is FULL
3) Start in RECOVERY
4) WIPE battery stats
5) RESTART android (yes, it might already be on 98% or so)
6) USE phone heavily. Don't worry if it drops too fast. Use it till the Android system turns OFF automatically (it happens when your battery is below 1% - for me the phone was on 1% for about 40 mins. This is where it heavily myscalculated
7) PLUG IN your charger, TURN ON android and wait till it is FULLY charged again. (It is better if you don't use the phone at this charging up)
Now, after you disconnect the charger, you should still have 100% for some time (I've been using the phone for 32 mins - writing this post - and it is still on a hundred percent) and with this, I got back the 2-3 days battery life with normal usage.
Also, you should set WiFi to: "Never when plugged in" and by default I disable Data Network. But my phone is using WiFi all the time so it doesn't really matter
So to summerize this method, the key is to show the phone the battery's minimal capacity too, by using it till it is on null. Because with charging to 100% than wiping or flashing only introduces the maximum capacity to the system and the minimum is only guessed. THIS gives the faulty reportes and makes us think the phone drains too fast.
Try this method, than feel free to share your results

hi
I have the same problem. I bought it 2-3 days ago. today i charged it full while fone was off, switched on at around 8AM my usage detail was
3g was on
gmail on sync
skype on sync
5-10 min of skype calling
5 min of normal calling
5-10 min of facebook browsing through android app
30 min of chatting on skype
at 2PM the fone was at 20% battery. My wifi and gps were off all day.
is there anything i can do to get atleast 15 hours of battery with normal use

If you are having issues with your battery, before you try killing tasks, changing setting and what not and especially if you are running custom ROMs, then you need to recondition your battery. The same goes for anyone who is having high drain issues.
If you follow the steps I posted from someone else's post and then find that your battery is not having issues, then start looking at your modem (if using a custom ROM or you've upgraded to new firmware).

ive done a factory restore, ive found what my usage says idle 4% the display 80%
contrast is switched right down

i know im not using any custom roms im using the firmware that you download through kies

Maybe sounds silly, but do You have 3G / HSDPA full timeturned on and/or any data eating app(s) running in the background? Usually these drains my I9000 really fast. If I take care to turn stimes 3G off (only 2G allowed) and shutting down the app(s) which run in background make my phone usable for a day.

it's 100% normal to suck so much battery life if you are constantly using 3G or WiFi or long phone calls

I know how to disable HDSPA, but how to disable 3g? :S tnahks

You are using it or something in the background is using it.
Full-on use (gaming) burns about 20% per hour in my experience. Browsing might be a little less but not much because instead of using CPU/GPU power it uses data.
The screen is the major burn, how long does battery usage say the screen has been on?
My battery drain is always pretty much exactly 20%/hour screen time + 1%/hour on time. It will deviate from this if I've played alot of music (especially streaming) since it uses power but not the screen, this drain rate will depend on the player and type of music (built-in player playing from SD card is lean, Tune-in radio streaming over 3G is a hog that heats the phone up, Slacker is in between).

Could be a few reasons for that. If you've recently flashed a new firmware your battery stats may be messed up. Just run down your battery down a few times and it should sort itself out.
Maybe you turned your phone on while it was plugged in. This usually stuffs up the battery stats and can show as much as 30% extra battery when turned on that way. Always remove the charger before booting.
Also, to turn off 3g/hsdpa/data go to settings/wireless & network/network mode and select gsm only (2g). You can also download the widget '2g 3g' which will take you straight there. Also, you can uncheck 'use packet data'. This will kill all data which saves battery. I turn it back on with the widget whenever I need data again. The power button menu also has that option. I'm on 2.2.1 so it may differ if you are on 2.1.
Pretty sure you can still text with data off but may want to test it. If message fails then no. However mms send/receive won't work I think.

i can do 5 to 6 hours straight of 3G browsing with screen on auto before it runs dry
3G + Screen = high power eaters

there's no battery stats trick . its just a logfile that's stored. nothing else. the trick you're probably talking about is calibration of the battery.
drain fully, charge to full while powered off. one or two charges like this should sort it.

Hey I have a bell i9000 and I have to say that I'm extremely happy with my battery life, I've been unplugged since 9 am, its 7:30 now and my battery indicator is reading 37% with above average use (some phone calls, gaming, browsing...) I would advise you to do these things:
1) install darky's rom (9.2)
2) flash speedmod kernel 13b (very good on the battery)
3) use setcpu and set with these values, max:800mhz, min:100mhz (conservative), and add a profile for screen off with min/max @ 100 mhz and 100 priority level (don't worry, your phone will still feel snappy even @ 800mhz)
4) use a black wallpaper, since black is rendered by turning off pixels on an amoled display.
You should see some improvements, hope it helps!

Why are people getting amazing battrry life?

I've seen a lot of people reporting unreasonably(for me) great battery
life , like three days WITH usage. Even for CM7 based ROMs, they( most people seen reporting) also get a day and half or two.
But for my personal experience, I have used my phone six months, and the best I got is 1.5 days WITH usage.
How do those people have those huge battery life? Or am I missing something?

Do you use juice defender? If you tweak your phone right up, then don't use it you might get 3 days if you did correct first charge etc, but in reality most people charge their phone everyday as they use them, it is a smart phone...ie a computer, my laptop lasts 4 hours! T there is no point in having a smart phone if you don't hammer the pants of it!

i'm facing pretty low battery life problem also
back then i remember when my phone is on idle, every 5 min only consume about 5ma(according to battery monitor widget), but recently i have no idea why , idle will consume up to 80ma every 5 min, i have very little apps installed and most of it doesn't have push notification nor sync
Another main point, i'm on 3G instead of hsdpa, i expect much better battery life to be honest, i'm currently on Juwe's smart edition 5.3

check the processes
First of all check what processes are consuming more memory and CPU.
Try using "Usage Timeliness Free" app, which will show you which application is eating up your memory thus battery.
It has got option to terminate unwanted apps as well.

Mine lasts about 7/8 hours at most with wifi turned off and some bloatware apps frozen aswell.
I've had the phone a year so I dont no if my battery is ready for the bin or if its something to do with flashing cf-root.
It runs out so quick I've got to make sure its on charge every night in case it dies and my alarm doesn't go off for work in the morning ha

One major difference people overlook is how hard the radio works to get a signal. E.g. At home with WiFi and 3G on I lose about 10% battery overnight of the phone sitting idle. At work I lose closer to 45% for the for the same period. Naturally when I use the phone it'll be flat at the end of each day.

[Q]Battery Life on LG O2x, how to make it last long?

Hey guys, just got my O2x a week ago and its great. It was flashed with 2.3 and at some point I tested updating using LG Suite and I went to 2.2.2
Anyway, just asking if how long do your batteries (stock) last? Tested mine about 3 days ago and within a day it got drained. Just using browser and played some music and that's it, no Youtube or heavy games or whatsoever. Already rooted my phone and removed everything that LG has there except for the keyboard, Suite, Mobile Support, and Home Launcher. Still, same results. Please help!!

I have been using the free version of juice defender and that has help my battery a little so I now cab get a good couple of days out of it. The free version only really stops data when the phone is locked but it seems to work quite well. I also installed juice plotter to see when my battery gets eaten.

Thanks will do that. So basically battery drains more if mobile data is on? Haven't really experience that on my old phone (which is not Android OS).

I had to charge mine every night and sometimes 2 times a day.
Now, on a GB ROM, and with mobile data OFF, it last for at least a day (24h). This is with WiFi on (when awake of course).
Install a widget to quickly turn on/off mobile data, and only use it when you need. Then your battery will not drain that quickly.
Sorry for my bad english
My battery "record" is over 2 days Well, actually allmost 4 days, but then I didn't have WiFi on neither..

Mobile data is the killer only for badly done apps. Things like fb and twitter that sync every hour etc. Make sure when you install every app you check its sync status. Make them as infrequent as possible
Also try see how low you can get the brightness. Mine stays at 30% until out in the sun (have a widget to up it).
Remember even if not using your phone at home etc to switch tho wifi on as its much better
On good days can get 30/40 hours between charges when low use
Sent from my LG-P990 using XDA App

Worth to mention is that to get the less battery drain from turning on the wifi you have to turn of the data. Some people forget that and leave both on making it a double drain.
My only tip that I have that I know works is use it as little as possible. Turn off every thing that's not needed in the matter of syncing.

I'm no expert but is that right? All of the data goes through the wifi when on and connected so data connection is irrelevant surely?
Sent from my LG-P990 using XDA App

Thanks for the input and somehow, I can feel the effects now. Also put LBE Security and turned off most mobile data permission on my apps and even if my Wifi is on, not much of a battery drain but at least it has less loss.

i think that 1day is the real time of this battery with 1charge...intense use...

Yes when wifi is on data is automatically off.... You cannot have both on...
Wifi is no very power consuming when it's connected idle to a network, but think to turn it off if no hotspot is there because network scan drains a lot.

O_O My phone came with v20c 2.2.2 and had no issues, ran 3days per charge. Wish I had backups of original ril and BB for they were 100% on any I've tried since going through a bunch of custom roms.

I get 10 hours of *idle* time with 3g enabled. With Juicedefender things are okay, I almost always make it through the day and sometimes even 2 days when I'm not doing anything, but the battery just goes nuts if you use it. Sometimes I browse the web for a minute and bam 5% is gone, and I'm thinking to myself "what the hell just happened?".
You have to be very careful with apps that do not close properly. I discovered that Spotify was draining my phone like crazy and causing it to become very hot (draining it even faster, heat = dead battery in no-time) with no way to prevent this other than uninstalling the app. Then I installed a beta version of Spotify from their website and all is well. AccuWeather also goes nuts sometimes but that's resolved by deleting the widget on my home screen.
I run the latest nightly of CM7. Battery life seems to be about the same as the stock ROM for me. What's interesting is that active 3g data use drains the battery more than playing a game. I can play emulated PSX games for about 5 hours straight on a full battery with data controlled by JD.

Everyone should try the latest rom v20e (or the derivated version topogigi's rom). For me, it improves battery a lot! I don't even use Juice defender (and some people said it worsens battery).

v20e
yes Im on V20e and my battery is preety good !
Almost 2 days and I write almost 100 messanger/day and always wifi on checking emails,fb and more !

Hey guys, haven't posted since testing for about week, I guess...
Anyway, battery seems to be ok now. Juice Defender and Plotter works great, plus now on sleep, it just drain 1% per 2-3hrs or sometimes nothing at all, and its not SOD thats for sure.
Also tried Battery Calibration, it worked somehow also so with lots of messaging, wifi, FB, Tap Sonic, plus downloading torrents, lasted 24hrs in full charge with constant use.

2g + Wi-Fi drains the battery much faster than 3G + Wi-Fi for me. Both have a good signal strength.
Anyone know why this is?
