[Q] Fast battery drain after gingerbread, anybody else experiencing it?

Well after many many tries with topogigi's rom i had a lot of battery drain, after a while i thought its probably ok cause its a gb leak, probably its not that bad.
well after few days using it i decided to change back to froyo so i changed to FR19 from modaco but i have the same drainage really really big and really fast, i use the wifi for like 2 or 3 minutes and it goes down like 5 %.
My question is this normal? is my battery broken?
i did the calibration couple of times, i checked the usage of battery, just the "0" and "1023" proccesses using a lot of battery, i also checked if it was some app runing in the background but nothing seem wrong.
can you guys help me with these issues do you think i should change the battery or just keep calibrating it.
BTW i also read about how the battery Mv should be at 4200Mv when its at 100% but mine is just at 4170Mv and suddenly goes down to 4112 or less.
I hope you can help cause this is really annoying me a lot.
Greetings

Did you do a factory reset after updating to gingerbread, you need to do a factory reset, after your battery should be fine, make sure to take your SD card out.

Gingerbread is not battery friendly. With tweaked ROMs and tweaked kernels you can have correct results (see my config below), but Froyo 10d is stilll a reference hard to reach...

this could be many diff things, what i would do is 1 of 3 things:
1- try to calibrate it again
2- try a new kernel (maybe an sbc kernel, it might work better for you)
3- maybe try to flash a new rom for a bit and see if the rom you are running at the moment just doesn't like your phone.
at the moment i am running the decks rom for gingerbread and svz 2.2.1 kernel, however i just like to test new things but what has worked the best for me is the godmode (V9) kernel. i stopped using it because he is no longer updating his kernels but with godmode kernel and cm7 my phone lasted me a total of 1 day and 6 hours on 1 charge.

well thanks a lot for the help green arrow, what i did know was i charge full on and off after that delete battery stats manually calibrate it with battery monitor widget then turn off charge a little bit again turn on delete battery stats again and reboot this worked for me from 9:30 pm to 8 am just wasted 8% sleeping but anyways i thought it was too much so i checked better battery stats so there is a process called nvrm daemon the weird thing is that i dont have an overclocked kernel and im not using daemon so i wonder what it is.
if you want i can attach a screencap so you can help a little bit with this oddly changes with my battery.
Another thing is during night there was some changes it went from 2mh to 60mh then it start going down until 10mh at 7:30 am, if you want i can add the history report from battery monitor widget.
And finally im using gr4 Modaco's with stock kernel. Btw i changed my RIL to the v20j version the one that came with the rom and it seem pretty good after 10 minutes it sticked to 2mh.
well im gonna take some screens and upload them for you.

Some screens so i can get some more help

this may not be much help but, turn off your internet (3g/2g) and your wifi, and your 4g if you put it on, and your sync. let me know if you see some change. if you do then just turn on your internet when you need it but leave it off on a normal bases.

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

Galaxy tab P7300 battery drain in 20 min

Hi all. After installing custom rom official from p7500 my battery got crazy and drains out after 20-30 min even after i charge it all night long. I did a stock recovery i also tried another rom but same problem with ALL ROMS. stock or costums! Need help plz.

We are in the same boat, most of us is facing this issue, but there is not a known fix.
We have to wait an answer from dev, KK, for a real idea on how to fix it.
Inviato da Tapatalk

Yep, same here (7310). Getting bootloops sometimes too. Tab completely destroyed. Battery doesn't even last long enough to fool a pawn shop into buying it.

Someone report that an attempt to fix is to go in cwm and let drain battery until it shutdown by itself, then recharge. Just give it a try.

Hi. Had same problem. Even nandroid recovery has the bug.
But i have my solution found. Now i am on KoldKaffee rom (it is suberb) - an the BATTERY WAS WONDERFUL
The failure was - that we flashed the Custom Rom with a not fully charged battery.
Okay what i do.
1. Loaded the akku - how much it goes - that i have enough for return to go back to stock 3.2
2. 3 x Wipe + delete Battery Stats in Recovery
3. Go into Stock 3.2 and do FACTORY RESET in Settings
4. after Reboot - shut down the 8.9 (turn power off)
5. USE POWER KABEL WITH PC (loading will take time
6. after it is full - you can install KK rom again

Try it,it works!

Has anyone tried to install battery calibration from the market? If you install a custom rom, charge your battery to the max. Open battery calibration (needs root) reset your stats unplug the charger and use the tablet until it powers down by itself (do not turn it off with the off button, sleep is ok, complete off NOT).
That always is the fix when installing it on my Samsung phone. After that the battery acts normal again. No need to wipe 3 times, install stock or whatsoever.

A lot of sites say battery calibration does nothing and is a myth or something, but I tried it anyway.
I'll give the CMW battery drain method a go.

I did the cwm method. Before do it i installed with odin a stock rom. I let the battery drain with cwm opened and then i did a full charge. Now battery is better. No so good than before but much better from yesterday. 4 hours now and its at 60%. I am still at stock 3.2. Ill try again for second time full drain battery with cwm and ill do a full recharge again before use. Hope this works.

I just gotta get the battery to drain slow enough to be able to sell it to a pawn shop now really... Heh.

I did this!
I let my tab be on charge until it was completely full (tab on), then I unplugged the charger and rebooted in to recovery (ClockworkMod Recovery v5.5.0.4) and did a battery stats wipe. When i rebooted it first did that blank screen boot (same as when i installed the rom).
I did this 5am this morning and now after c:a 16hours standby and 1hour surf/games its down to 85%! :fingers-crossed:

I'm on KK 7510 ICS port.

I had massive battery after flashing the P7500XXLQ8 P7500OXALQ8 for P7300 v2 (I came from cm-10).
I didn't think to check my battery charge level before I flashed but I suspect it was around 30%.
The new from was great but the tab died under general use within 60 minutes.
The battery level indicator was erratic- moving up and down between restarts and charges.
Problem persisted after full wipe and stock 3.2 flash via Odin3.
After flashing back to 3.2 i took the advice from astuermer and drained my system power, then rebooted into recovery and drained my battery for a further 5 hours until my tab was completely dead (yellow triangle next to the RED battery symbol on lpm animation).
Then proceeded to fully charge tab (while powered off) for 5 hours until 100%. Wiped everything and reflashed ICS rom.
With music player going, 3g browsing and full screen brightness on I'm on 94% after 60 minutes use. So far so good...
Thanks astuermer for helping us and kk for an awesome port

10 hours later.......playing music and 3g browsing for most of the morning and my battery is at 81%....looking good

Well some may claim it's a myth, but when I use a custom rom on my phone. I lasts three hours before calibration and 2 days after. So I am a firm believer. The easy way to check is, when your device claims it's running on fumes. I turn it off and plug in the charger. Then the battery charge indicator comes in screen. Claiming it's 2 third full. So that's when I know to calibrate.

Some hints.
Discharged the battery till system shutdown. Then connected to charger & the start of charging [email protected]%. Upon removal of charger, it says low battery & shuts down.
In cwm recovery now for draining the balance juices to start charging afresh.

hey Guys,
I attempted the cwm battery drain and from personal expeirence can confirm it doesnt work
I rebooted into cwm throught out the entire day until it wouldnt even turn on anymore
i then charged for the enitre day and booted into android to no avail, the problem still persists ... if anything seems more erratic and random than before, 97 to 84 in a minute, then suddently reported 94, then dead.... put on the charger, only works, take it off its working, but draining FAST..
Plan B... cwm charge to 100%.... clear cache, dalvik, battery etc etc reflash rom.... problem still persists and now its beyond me to explain why this is happening
will revert to 3.2
dont get me wrong, the first few days it worked it felt like new life in my tab, was having so much fun, so smooth, accapteble battery. hope this is resolved

Even getting back to hc 3.2 will not solve this issue.

As i wrote i did all these things. I did a secont full drain battery from cwm and a full charge with pad open till 100%. After that i went to cwm again with battery 99% i installed p7500 ics for my p7300 and same time(after the installation before reboot the device) i did a full wipe all things and also battery stats. My battery now afte 1 day 1 hour used time is at 59%. You can see it at the photo. I will do a third battery drain also with cwm after all that and then a full charge again. I HOPE I HELLPED...

[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.

[Guide] Calibrating your battery

Ok so I'm going to tell you how to calibrate your battery, this is advised every time you flash a new ROM, you're probably asking why yourself why you would do this...
Advantages: every time you flash a new ROM your system gets confused and can result in your battery stats being incorrect meaning your phone might believe it has 0% battery and shut down despite having power left, this will fix this and so will actually give you a longer battery life
What you need:
The ability to read, and either
Cwm or the app "Battery calibrator" from Google play (I recommend the app)
OK.. so first charge your phone to 100% battery then go to either cwm recovery mode or the app, on cwm go to advanced settings and delete battery stats, on "battery calibrator" simply click the calibrate button and this will reset your battery data...
After doing either of these methods you're done, its recommended to let your battery drain completely before charging again but not needed...
I have included a screenshot of the very easy to use battery callibrator app... (having a problem with upload ill try in next post)
---I've definitely noticed that my battery lasts longer especially at staying over 80% before it would drain from 100 to 80 in literally half an hour now each percentage is equal and drains alot slower---
IF THIS GUIDE HAS HELPED YOU DONT FORGET TO SAY THANKS

There's no way to specifically see if your device needs calibrating which is why it's recommended after each flash, however if you believe your battery is draining quickly even while doing nothing on your device it's probably because you need to calibrate
Just uploaded the screenshot of "Battery calibrator app"

Clearing battery life wont give you a longer battery life. It just corrects the battery reading. Thats about it.

And other simpler way to calibrate is to reboot recovery - Go to advanced - Wipe battery stats.

When I clicked on the calibration button once it said calibrated....when I again clicked it prompted your phone is not rooted...I am running jellyblast rom....so device is definatly rooted....after some time it prompted this....moreover the app is not showing in superuser list....

The recovery method is in the guide, also this does extend your battery if your phone is switching off early because it believes you have no battery left when you do
Also to the guy who's having problems: that's normal after you click calibrate once you're done if you click it again you get that message

It says batterystats.bin not found when i pressed the button second time means the device is calibrated as it got deleted when I first pressed the calibration button.....right?

Yes, once you clicked it it's done, and if you click it again that happens... It's all normal, the battery stats will be recreated when you run out of Battery which is why it's recommended to let it all run out

Used my ACE without calibration (on Simplicity v3.5 Rom) - Phone was fully loaded, after around 10 min it was from 100% to ~90-85%.
This morning i calibrated and after ~10 min it was from 100% to 93% ... guess it helps?!

Yes it means it has calibrated your battery,
its giving a more accurate reading now,
P.S The only way this can help "Extend" your battery is if your phone was reading 0% and shutting down despite still having power left,
alot of people pming me asking how it extends your battery... So yes it can extend your battery.... sort of

Yeah, but i have to add:
I'm using "One power guard" atm - this app is really awesome and helps alot against battery draining - i like this, plus Supercharge, DOMscript and battery calibration - its really nice

Yeah I've recently tested this, it even has an official review by XDA, but tbh it basically just changes your CPU parameters quickly (Several other apps can do this such as frills CPU meter app) and when certain conditions are met such as low battery, this app is by far the best of its kind (Fully customisable and autimated) but ... I don't really need it my phone lasts all day even when I'm gaming... I only lose 5-10% battery ovetnight
It does have a nice layout and good features graphs etc but... meh, my phones working good already
