Hmm
Bionic has
bigger screen, thus need more power
dual core process, thus need more power
LTE 4G, thus need more power
Hard to compare it against fascinate. Why my Lexus GS drain more gas than my Camry XLE V6. they are both V6..heheeh

Try not doing that.

Looks like you have no 4G where you are... make sure you are set to CDMA only in the network settings.

My battery seems to suck a little bit, too. On the drive in to work this morning, a 1 hour commute, my bionic sat on the seat next to me without being used. It still managed to chomp through 20% of the battery. So, basically at that rate, I'll get 5 hours of standby. Wonder if something is wrong?
Bluetooth (which seems to be a battery hog) was off, wifi was off... not sure what to do other than swap the battery with a replacement.

install system panel, turn on monitoring for everything, use that to determine how much cpu useage apps are using.
if you have an app(s) that are using near 100% cpu useage 24x7 that would happen

I have had the phone since 9am yesterday and have not been impressed with the battery so far. Today was the first full charge and I am at 60% after 2.5hrs. Most of my power consumption has been "Cell Standby" and not the screen which I would normally see.

Thanks! Will give it a try and report back. I hope I can get this resolved.
UPDATE: Installed System Panel and ran it for a couple days. Nothing seemed out of the ordinary. I let the phone discharge completely and then charged it completely before turning it back on. I got about 26 hours of moderate use before it needed to be charged again. Slightly heavier use got me to about 15 hours. There doesn't appear to be anything wrong, and the battery is light-years better than that of my old Eris. So I'm happy!

I'm actually getting pretty good battery life.. I use wifi when im home and at the office. With moderate to heavy use I didn't need to charge my phone until at least 18 hours. I know most say its not necessary, but I have a habit of fully charging my phone prior to first use and allowing it to drain completely before recharging.. perhaps that helped..

My battery has been doing great so far. Been using it a lot today and I'm at 45 percent after 8 hours of use. In me experience, it takes a few full charges before a battery gets fully calibrated. I've read that elsewhere as well. I've been very satisfied so far with battery life. I keep it on wifi at home and work so that probably helps alot.

I would say do a few discharge/full charge cycles on the phone first. Give it a few days to calibrate properly.
Also custom ROM's should help to remove undoubtable bloat that this phone comes with.

No 4G here either, didn't think to change that. Thanks! One additional question about the battery. I have a battery widget that displays the % remaining. I noticed that it drops in 10% increments instead of 1% like it used to on my Eris. I also checked About Phone > Status > Battery level and it seemed to decrease in 10% increments there as well. Is this normal with the Bionic? Or is something wrong with mine?
Has anyone else noticed this?

mine seems to be dropping by 10% as well, but my usage has been fairly good. Much better yesterday than today. Should know better if a day or two.

Task killers are bad since Froyo (2.2). Android actively manages applications and shuts them down when space is needed. Your task killed just winds up arm-wrestling with the OS, making both work overtime and not accomplishing a thing. Let the OS do what it's designed to do.
For those of you just starting with 4G, if you live in a non-4G area or are on the border where 4G and 3G constantly swap out, this will play hell on your battery, so turn 4G off unless you're in a place to take advantage of it.
Pentile screens are power sippers, so don't be surprised if your screen % is lower than normal.
I may be wrong, but I don't believe dual-core processors consume too much more power than single cores under normal circumstances.
Turn off bluetooth, satellite and wifi when not in use, and especially when unavailable. Leaving wifi up when you're away from home can chew up a lot of power as the phone is constantly seeking a signal.
Putting the screen on auto brightness may save some power. Also setting the screen time-out to a reasonable time will help.
Make sure you don't have a dozen accounts like Facebook, Gmail, Yahoo and Twitter checking for updates constantly.
You don't have to train lithium ion batteries like we used to with nickle-cadium back in the day, but your battery has some simple logic in it that takes care of housekeeping. When you first get it, and about once a month after, you should drain your phone's battery completely and then charge it back up. This helps the battery, and therefore the phone, understand how much power is left with greater accuracy. If you'd like to research this subject, I suggest Battery University and Apple.

I am having horrible battery issues now, my battery is not lasting 6 hours with very light usage.
right now my usages shows
Battery 15%
4h 56m 21s on battery
media 46%
cell standby 24%
phone idle 21%
voice calls 5%
display 4%
social location2%
this is the first time i have seen media at the top of the list, usually it is cell standby that has been using the most
this has been going on since saturday, i have two batteries and it does this on both, i figure it must be an app i loaded. i dont think i have loaded anything that i didnt use on my OGDroid but one of them must be disagreeing with the Bionic. i am planning and doing a factory reset tonight (as much as i hate doing it)
any other ideas or suggestions would be greatly appreciated.

This is a 4G pitfall. You're probably going in and out of 4G/3G coverage... it may seem like a lot, but when your phone is constantly looking for 4G the battery goes QUICK. Your best bet? Turn on 3G only (cdma only) when you drive. There are widgets in the market that will take you directly to the setting.

Right now im at 1 day 3 hours 46 minutes with 30% left. That's with an extended battery and mild use. Just testing, browsing xda app, and reading news in pulse. Few emails and some web browsing.

Not sure what my battery life was before i rooted and debloated since i ran stock for about 15 mins, but with very heavy use i get about 7 hrs, with normal use i get about 16 hrs

Battery life is incredible on this phone.
Sent from my DROID BIONIC using xda premium

so I did a hard reset and sent my phone back to factory default :-( and let it sit for a few hours with nothing on it except for juice plotter so i could monitor it and it was still pretty crappy I then removed everything i had copied from both SD cards (ie. photos, music and movies from my OGDroid) and let it sit for a few more hours and the batterylife improved dramatically, I am guessing there is an indexing service or a DRM service of some sort that is part of MOTOBLUR and it must have been continually hitting my cards.
today the battery life is back to normal. i have installed just a few things like friendcaster adwlauncher and a few others that i normally have and have used the phone moderately for the last 3 hours and it appears i might get another 10 - 12 hours outta of it..
does anyone know why i had issues when i put the media from my old phone onto my new one, do photos and videos have to be in a specific directory or on one of the two cards specifically??
any help would be appreciated.

[Q] Battery Problems - falling from 70 to 0 %

Hello,
i have a bad problem with my LG starting from day one when i bought it. I tried many things now, to no avail.
The problem is that sometimes my battery falls from high percent value to 0 just in one second. then the mobile goes out and i have to charge it, even it was nearly full some minutes ago.
Another problem is a warm mobile in standby mode when i have mobile inet active, and battery wont last longer than 4 hours. With WIFI it doesnt get warm but starts to decerase RAM until the mobile is unusable (timeouts, freezes, ect)
So there are 3 problems, i think related together somehow:
1. sudden Akku drainage, falling from high percent value to zero
2. fast akku drainage with mobile inet on, doesnt fall from #to zero, but get used up very fast
3. Unusable mobile due to RAM issues when WIFI activated.
Here are following some pics and a Log attached from Android Stats. Here you can see starting at 9.34 the bettery recalculations, in very short timeframes.
Can someone see any issues from the log what could be the problem?
The situation was like this: I recharged yesterday evening, and turned mobile inet on. Then i went to sleep. In the morning i saw that i had no connection to google servers (icons white instead on green) but i saw the battery was only drained 2% over night so i thought not bad.
I reactivated internet (mobile) in hope to get conn to google servers. Well, i got it but in same time the battery got drained from 98% to just 40% in one second. Since then the mobile stays warm. I have auto sync deactivated.

I forgot:
Android 2.3.4 original, rooted but nothing changed on firmware/rom/baseband/anything

So i inserted screens now.

you have some kind of background application that doesnt let your phone enter deep sleep mode to lower cpu frequency and conserve battery (phone is awake when screen is not on, you can see the activity in the pictures). you should check what app is using most of the CPU time, it might not be code optimized and might be sucking too much of the battery.
also, it might help resetting the battery stats, search a bit and find some info on that (short version, charge it to 100%, let it for another hour plugged in, go in CM, delete battery stats, restart).
worst case scenario, your battery is busted and a replacement might be needed. hope that helps.

andrei.je said:
just a hint : most battery consumption can be checked in the battery stats, on the activity graph : awake vs screen on - if awake and screen on are not synced in the activity graph (should have same lines) then you have a problem. meaning when your phone has its screen off it should go into deep sleep mode (lower cpu frequency) but if you the phone is awake while screen is off, you have an application installed that won't let your phone sleep and just keeps using the cpu and sucking the battery.
this is mostly applied to standby battery life, if you are playing a game/watching a movie, doesn't really matter screen is on, cpu/gpu is sucking the battery.
my worst battery life while i had the O2X was about 16h, but that's with normal phone use (no games - you can have a psp for that, no music - you can have an ipod for that), mostly emails, browsing, IMs, calls/texts all day long also best battery life was 2d 10h (mostly on standby)

Thanks for also answering my post on the other topic.
It may be that theres an app that keep our phone from sleep, but even with this app, when i dont turn on wifi or mobile internet, the mobile runs 6 days straight. This is no joke, offline it could hold 6 days, i have a screen of where it looses 8% in 28 hours. And as you can see on my screen, it happens from one second to the other.
I already changed the phone the third time now, even with very few installed apps, this remains. I had it first time on day one when bought th mobile. Since then in all 3 mobiles maybe 15 times.
Anyway, it bothered me, but not as much as that the phone went nearly unusable with internet active. Always at 50 mb ram. So it was basically an offline only phone. In my 2 tests, both 5 days without internet, the mobile neither went slow, nor went off, nor lost battry, nor anything. Very fast LG OS. Until internet...
Anyway, now i installed Chuck Norris CM /MIUI ROM, lets see what happens. Until now its so smooth and soft, it feels like a complete other mobile. Also with wifi active... but i cannot say anything until tomorrow.
I tested already a lot of System Analyzer apps but theres really not much to see. Nothing seem to use much battery in whole. At least nothing that explains a loss of 70% in 5 seconds.
I posted a log here, thats the best thing to see i guess, but i cannot really read it well :-(
Anyway, your help is appreciated

I think the problem is caused by the battery stat file. Avoiding the techinical causes you should only charge the phone untill 100% and using battery calibration (you can donwload it for free from market) calibrate the battery! Hope to be helpful ^_*

HTC Vivid Battery

Omg the battery life sucks so much, is there anything I could do to fix this, its terrible... Like I would fully charge it then use it for 5 minutes and it will drain to about 5-6%

Did you just get the phone? You shouldn't be draining to 5% after 5 minutes no matter what you are doing... that's unreal. Unless you are starting from 10%...

You've gotta be a bit more specific than that. Exaggeration prevents us from helping you.
A few basic questions:
What ROM are you on?
Describe your "us[ing] it for 5 minutes".
Take a screenshot of your battery use screen and post it here or something (both the expanded graph and the app list would be good enough).

which rom you are using？ Normally it should not like what you said.

O_O
Do you have GPS, Wifi, Bluetooth, Brightness maxed out, Downloading multiple things at once while playing multiple games or something?
Have you tried recalibrating your battery?
i have experienced amazing battery life on my Vivid, running Rum Float Beta 1, I can browse the web, play store, and download a few things over the course of two hours and my battery MIGHT drop down to 97% at the ,most.
Calibrated my battery stats though and let it fully cycle a few times.
just in case you don't know how.
Step 1: Let battery get VERY low.
Step 2: Boot into CWM Recovery.
Step 3: Clear battery stats (Advanced Settings > Clear Battery Stats)
Step 4: Reboot device.
Step 5: Let battery die fully.
Step 6: Plug in, do NOT turn on until FULLY charged.
Step 7: Before turning it on, boot into recovery and clear your battery stats once more.
Step 8: Use phone as normal, until battery gets critically low.
Step 9: Mercilessly kill your battery. Charge w/o turning it on again.
Step 10: When fully charged you may turn it on normally and resume regular usage.
That should help a bit with your battery issues. I know mine was dying pretty easily before I did the above.

I am using HoliRaider, Like a couple of days ago I was texting multiple people, without tuning of the screen and go use other apps and such.. It willl go from 100 to 96 in a few minutes.

Just some observations i took today using my vivid lightly to medium use i guess.Checked email several times,checked facebook several times,sent and received several text,3 short phone calls,checked and updated weather several times,Took 3 pictures and uploaded them to facebook,read a few pages of news on the web,and checked battery status throughout the day.I think that's about it lol.Anyways i took 3 screenshots of the battery level during the whole day today.To say the least im very impressed with the battery of this phone.Im running the new ICS 4.0 Sense 3.6 that was leaked.I have my sync setting to min needs.All vibration is off except for when typing in a message only because i haven't figured out how to disable it yet.Of course my battery has been cycled and is broke in well now.
Im still looking for ways to extend the battery even further.

Using this ICS it really don't say a percentage but looks like around 30%.Automatic is way to bright and really kills the battery.

Dang, that's some killer battery life. I'm not getting nearly as much as that on RumRaider (GB), and I keep my Wifi and Mobile Data off whenever I'm not using it.

Yes it is but i don't get near that with heavy use or if i get alot of email's etc.
At 14 hours today its down to 14% right now.Loading webpages and facebook really drains it quick.Plus watching videos.I wish there was a way to disable the led i think this would help greatly.I have all the notification flash settings off for everything but it still flashes when i get an email or missed call.

I managed to get even more time on one charge.Used the phone on WIFI most of the time during this charge and it seemed to do even better.
One Day One Hour & Seven Minutes with 14% left

On stock battery I struggle to get 6 hours.
However, this weekend I was able to get 16 HOURS!
What was the difference? This weekend I was on vacation. I talked much less on it and I was out of 4G area.
All the tweaking with screen brightness, data connections, CPU speed all make a small difference in comparison to voice.
Look at battery screenshots of people with long battery life. They don't talk on the phone. If you want good battery life,
get a bigger battery. Motorola gets it.... they doubled the size of their Razr Maxx battery. You'll see more of these 3000mah+ battery phones in the future.

also i've found out if you turn off auto-sync it helps alot. i turned off auto-sync recently and expierienced at least a 2-3 hour increase in battery life

The issue is the battery size is absolutely ridiculous. Why in gods name they put such a small battery on an lte phone is beyond me. And alot of other htc phones at least have a name brand extended battery where you can still get a case. Me personally I have an aftermarket second battery and external charger as well as an external battery but it gets old. I'm not that bad but I probably if I'm lucky get 8 hours a charge. I really think ultimately its why I might look for something else when I get caught up financially, probably a nexus.
I just got better battery stats in hopes I can locate the source of the problem

anyways...i get 13-15 hours with 20% left
I leave my screen brightness on auto
WiFi and Data is always on (i live in an LTE area too...so im almost always connected to LTE)
I leave accounts and Sync on
i get anywhere between 3-4 and a half hours of screen on time
My bro has the same phone...he gets about 8 hours of battery life, with about 1-2 hours of screen on time...we both have the same exact setup...

get the wcx illuminati rom.. the battery life gets increased by a ton. :victory: the only problem is you have to sign up and have ten posts before being able to download

[Q] Weird "battery drain" when lightly using the phone

Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance

I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.

Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).

I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.

Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.

@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?

Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?

Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/

I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.

I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.

Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.

What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.

The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.

Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.

I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.

Question SOT is lesss really less

I've seen a maximum of 5 hours of SOT since I got the phone. My sot time is very short when I see other people's sot times. I always use the phone with the following features; +4G +always bluetooth +always location + no wifi +always sync +dolby atmos +dark mode +when i got notifications aod. Although I turned off the settings I used, I still could not do this for more than 5 hours.

Show us a screenshot of battery usage when you are at 10% - not at 80% - then we can see where all your battery fuel is going.

Sure its from 2 days ago

Battery is draining extremely fast on Android 12 (BULK) as well...
Is there a way to know if our phones haven't been manufactured by Samsung?
- There is Korea but also Vietnam etc... this might have an impact somehow?

What are you doing on whatsapp....that's a huge drain....

whatsapp is always a huge drain if you use to send and receive messages. My solution to this was enable multi-device login. I, now, use Whatsapp mainly on my computer when I'm at work and then revert to the phone when I'm off. The led to a huge difference. What used 25%+ for whatsapp..now stands at 4-5% over the day.

Morning 7 to 5pm I m using WhatsApp for work. I m using 2 WhatsApp. Work WhatsApp isn't stop every minute always receiving several message. I can't stop WhatsApp because of work. I think that's why WhatsApp percent is so much

Does your battery run out by the end of your typical workday? Do you have to charge it during the day everyday, or can you get to the charger comfortably when going to sleep at night? SOT by itself isn't a very good metric when seen in isolation.

Are you mainly on Wi-Fi or mobile network? OP is on a building site so most likely on mobile network most of the day

So your battery level goes to 20% or below by every noon? Sheesh, that is indeed potato battery life...
But your screenshot suggests a pretty good standby time, nearly 11 hours usage and 72% remaining...
Maybe post the battery usage screenshot once your battery dips below 20% so we can try to pinpoint the issue?

Actually my battery level around %50 in noon. For example this screen shot is today after noon. In noon was %100

I am 90% sure that your battery drain is caused by the mediocre 4G signal which is used for internet at all times. A lot of power is basically being allocated to get a better signal and thus while you use WS all the time, your batt drains FAST. If you happen to have Wi-Fi for a day or two and the signal is maxed out, the battery will surely last longer. Generally speaking though, you cannot compare other peoples SOT to yours as most people do not use WS as much as you, nor 4G at all times.
There might be some other extra settings that could be altered to improve battery, like:
adaptive battery ON
enhanced processing OFF
location OFF
background data OFF
resolution to FHD
background usage limit to put rarely used apps to sleep
NFC OFF
nearby device scanning OFF
And of course the last version of android 11, as it seems A12 is not yet worthy or ruling the S21U. Sadly I have a feeling that Samsung might not fix A12 for the S21U as they are now releasing the S22. Hope I'm wrong.

The Big Battery drainers:
Screen - If you have manually set it high - Try Auto
Mobile Signal - Nothing you can do if its poor - unless possibility of WIFI
Location - Always On is a no no if you can help it - try use when app open only.
Background Data - Turn off for apps which its not reqd .
Also Since Android 12 I also seem to get lower SOT although my phone battery has been same since android 11. Im not sure if they changed the way they show/measure SOT now.
