[Q] Battery Usage Spikes? (mA) - T-Mobile LG G2x

It would seem that looking at my Battery Moniter I would get random spikes that send the (mA) into the 900's. Then slowly begin to drop after watching it for about 10 minutes where it starts off at 2(mA) for about an hour and a half. I'm not sure if its the 4g kicking in or not but Juice Defender should be stopping the 4g while the phone is off.
If I could get some input on what would cause such a spike then I would have an above average battery to last throughout the day.

I am kinda curious about this too. I don't personally have this problem but i read on one of the forums(outside of xda) that it was either a radio tower switch (back and forth between 2G and 3G/4G) or a loop in the actual programing.

Until the battery drivers are fixed none of the numbers reported will be very accurate.
Next time you think it is spiking to 900 or a high number try using a task killer and kill the battery monitor widget and then restart it...anytime I do that it then displays back down to 2mA.
...so to make a long story short dont trust anything it is telling you. The only accurate guage is physically how long the phone runs before it turns off.

Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?
I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.
Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.
This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.
I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU
This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though
when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.
Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.
Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....
Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.
i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.
If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).
W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....
What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.
At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

Love The Phone but...Battery Rant

Hey Guys,
I am usually just a silent observer on the boards and try and gain knowledge from all these amazing developers but my experience last night has pushed me to vent. I live Atlanta, and a Vendor had offered us some suite tickets to the Falcons Ravens game. Of course I would take those. Knowing this phone does not get the best battery life, I made sure to have the phone fully charged before I departed. I left the office at 5pm with a full charge. Throughout the night I would send a txt here and there and take a photo, nothing too strenuous I thought. As the game was coming to an end I looked down and saw that the phone was already in the yellow, not terrible since it should last me till I get to the car. I’m not thrilled because this means the phone charge has only lasted 6 hrs. I get off the mass transit station and go for my car key…..and it’s not there. I check all my pockets to find nothing. I am now screwed. No car, no phone, no charger. To cut the story short, I had to find a payphone (needle in a haystack) and call collect to my father, who has the only spare key. Needless to say he was not too please coming down at 2 am to get me out of the jam. I am just so furious that the phone died so quickly on me. It seems if I ever go out at night, if I’m not near a charger, that phone is dead within hours. Sorry for the rant, but its just the one major flaw about this phone. My old Tilt would last a couple days ( I know I know, small screen low processor) But a solid day out of these phones would be nice.
Do you manage the battery consumption by turning off unneeded features such as Bluetooth and Wi-Fi? Have you set the screen timeout to a few seconds of idle time? The display is the biggest consumer of battery power. Finally, when I know I'll be away from a power source for more than 6 hours, I put a fully charged spare battery in my pocket.
FYI the Galaxy S has one of the best batteries for a smart phone. With careful use and battery management, I routinely get 16 hours before a yellow warning.
I had much of your same problem in the first few weeks of having the captivate, prompting me to go buy two extra batteries and a charger off ebay ($10). I feel that upgrading to cognition 2.2 and using the task manager to stop facebook and such from always updating has saved a lot of life, and my phone will last a day to a day and a half on a single charge, so long as I put it into flight mode at night. then I just shut the phone down, switch out batteries, and turn it back on.
I have the screen set at the lowest possible brightness (11%). When i am out i never have bluetooth or wifi on. Perhpas there was a runaway app that was draining the battery. I have never gotten 16 hrs though. My max is about 12, and thats if i dont make any phone calls. You start making calls, it just kills the battery life on my phone. I did use to have a spare battery on my tilt, i might have to do the same with this phone.
It's most likely because your phone is not sleeping when the screen is off.
Download the "Spare Parts" app or just enter *#*#4696#*#* in your dialer and check out the "Battery History". If the Running % is almost full (around 80%-100%) during a day's use, your phone isn't sleeping when the screen is off which means battery is draining. Give it a reboot when that happens, but the known cause I've found was that WiFi causes this issue.
Are you sure you weren't losing signal when you were in the arena? When you lose signal the phone constantly searches for a signal causing your battery you drain.
I know in arenas you don't get a strong signal...
Just a thought
Turn on airplane mod when ur not really using your phone..
I have a great battery life. Especially when not using HSUPA. Try deleting your battery stats.
I typically see 12 to15% per hour drain with constant use.... meaning display is on all the time and I am on internet, phone laying idle overnight... 1%/hr tops. I do have a nice signal at home though... ranges from –70 to –85 so the modem is not working hard at all.

battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.
See my post here:
http://forum.xda-developers.com/showthread.php?goto=newpost&t=839935
Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.
I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.
Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.
Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.
Sent from my HTC Glacier using XDA App
I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.
I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.
I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.
My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.
I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.
I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.
heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life
Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.
It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

[Q] 9hrs unplugged, 44min display, 3hrs run time, 40% battery left

I have been having problems with my battery life pretty much since I have had this phone. I downloaded spare parts app to give me some insight because I have also noticed several times phone seems warm even when screen has been off for some time.
As of right now today, to give an example, my phone has been unplugged for the last 10hours and I only have 44% battery left. Says display is responsible for 71% of battery use yet screen has only been on for 44min of that time (and I have the brightness turned all the way down). According to spare parts "other usage" my "running" time is cause for 35% of batter use at over 3hours.
With these things in consideration I feel that there is something that is stopping the phone from properly sleeping due to the phone being warm at times display has been off for a while and the contrast between screen on and running time. Partial wake usage doesn't show much running under it as most listed items have only a sliver of a bar showing.
Can someone please lend me some guidance on how to further troubleshoot this problem?
i mean that type of battery consumption doesnt seem irregular to me...im at close to 10 hours for the day and have 59% left.
Are you in a shaky signal area? Thats one reason my phone gets warm. especially if its a fringe area where it cant decide between a 3G signal or 4G signal.
In spare parts there is a option for partial wake lock. If something is stuck at 100%, then you know you yuo have a rogue app thats causing your phone not to sleep
But can you confirm it being normal to see 34% time running under other usage settings for spare parts? Partial wake usage as said doesn't show much keeping a wake lock going.
As for signal, not too sure, very rarely if ever see a 3g change over. Is usually at 4g and occassionally hitting edge.
WOW, you get that good of battery out of yours? that seems epic haha, i get 3-4 hours tops.. i mean i abuse it, but still..
I charge mine at night. Ran it from 7am to 12am and it was at 34%.
Yeah see...7am to 12am and 34% remaining? No way I get that.
If it werent for the results I'm posting regarding "running" percentage from spare parts other usage and the screen on time I would just accept it as a phone deemed to have bad battery life, but it seems to me like something is going on and I guess I'm looking for someone to confirm or dismiss my suspicions.
Maybe I'm also a little spoiled coming off my G2 that was rooted running CM Rom and CPU ramping/cut down which in combination gave me, under the same amount of use, a situation where I was getting home at night and still having 40-50% battery left in comparison to the 15% I commonly see now.

once some custom kernels come out that let you uv/uc/oc then i would say you can expect the same type of results..i just went on a trip with a friend who has a g2 and he was constantly crying about his battery dying, (stock), where as I only had to charge mine on average 1.5 times a day with moderate to heavy usage. I find this battery phenomenal compared to all the other android devices ive owned and tested
damn!
i charge mine every other day.. hehehe i dont abuse it or anything though.. just regular internet every few minutes or so.. i have the BETA juicedefender installed guess that helps a lot. data is off when the screen is off, set it to agressive..
here is the app hope it helps...
I noticed the same problem,i brought this phone on saturday and was very impressed with the battery until yesterday night I noticed the same thing, my phone was at 50% and I had it sleeping then I get the battery low notification 10 minutes later and the back of the phone was real hot. This can't be normal cuz I have the same apps installed from 2 days ago and I was using the phone heavily even using mobile ap and still didn't have this problem, if you guys find a solution please share it with me.

Anyone else having temperature issues?

After logging the temperature for a few days I've noticed a direct correlation between phone temperature and battery life. The phone drains 1% every 3-4 minutes when its at or above 35. when its around 27° or lower it only drains about 5% per hour... I'm having an issue however. Today my phone was extremely hot. Right under 40° all day... with the screen off 90% of the time. Tonight I'm doing a test I've removed the back cover and its nowhere close to as hot as it was.before. I'm starting to think the battery cover is too close to the battery and internals thus causing overheating issues. I love this phone but I may try to swap it out for another while I still can. Has anyone else noticed similar issues? I'm underclocked at 800mhz screen brightness 10%. Does at&t charge a restocking fee if I return it?

well there must be a big current draw for it too get hot. android has a bug that shows up occasionally where the radio consumes large amounts of power. also 2.3.3 has a similar bug where the system wont sleep, this should only effect gingerbread but it may just be more frequent in gingerbread.
check battery usage in settings>about phone. if anything other than the display is over 50% there is a problem. if it is android system then shut it down and pull the battery for a few minutes, start it back up. if it is the cell radio then put it in airplane mode for a minute and take it out of airplane mode.
removing the cover may help it stay cool but there isnt enough heat there to cause battery drain, instead the cause of the battery drain must also be the source of the heat.
was almost thinking bout buying this phone as its very hot in africa this could burn my hands
I am on my second Infuse.
My first one had battery charging issues, and compare to the current one it was also a battery hog. I did not put two and two together until the current one i have, but the first one would get hot around the camera area with just streaming slacker while browsing the web.
I exchanged it like 4 days after i got it due to it taking 6.5 hours to charge from 5% to 100%.
I just had the same issue... it was down to 10% so I put it on the charger... 3 hours later I looked back and its barley on 40%. It took 7 hours to fully charge last night. Something isn't right. Now my screen is completely set to off and I'm underclockong and its gone from 24° to 39° in 5 minutes.

please check the battery usage in about phone. if anything other than the screen is around 50% there is a problem, the solution may be as easy as starting airplane modeand turning it off
