[Q] 8 wifi tab battery drain - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hi, I have been wondering huge battery drain of the device. With wifi on, it lasts max 2 days from full to empty, with little usage.
If I turn wifi off, drain stops. Tried it last night, didnt use battery at all.
I have tested original rom, cm11 and omni, same behavior with all. With or without custom kernels. Always system wipe before flash.
Do you guys have same kind of drain with wifi?

[Q] high battery drain on all roms!

Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...
First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next
And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.
you might want to try a new radio too
same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

how many hours you are getting now....with regular usage ????
I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(
Yeah this is no fun...

Delete all htc account and calibrate the battery

[Q] Battery drained over night!

I have a problem with latest version of Android Revolution HD 6.1.0.
Yesterday afternoon I fully charged my phone and used it only a little bit until I went to bed and turned the phone off.
Today when I turned my phone on again (fastboot) I was shocked: Battery was at 25%.
How can the battery drain that fast over night while turned off?
I am using the correct Radio (12.62.60.27_26.13.04.19_M), Superwiped before flashing new version of ARHD and also cleaned battery stats when it was fully charged.
Can you please help me finding out what is causing this?
I´m not getting that much battery life out of my HTC Desire HD either when running ARHD 6.1.0 ... Is there any RADIO that could help?
Weird - I have similar problem with 6.1 Revolution.
Battery seems fine all day, put it on my bedside table last night at over 80% battery...woke up this morning with 2% battery left!!
really weird.

I'm gonna download Current Widget now and enable the log option and see what is happening in the log overnight.
Post the log up then and see if someone can take a look.
Any news about this? I feel that mine is dropping rather fast aswell..
Saturday i installed 6.1, installed applications and used the phone.. At a total screen was on for 4 hours... After a total of 5 hours, the phone was down to 15% battery...
Does application installation take that much or is something not quite right? I feel that i had more batterytime with 5.2.4..
Now i can basically see the battery values dropping while using the phone.. I have current widget and sometimes when i start the screen and go to home screen it says way above 500mA, is this right?
Well i don't have any issues, while using ARHD 6.1 with the recommended Radio

How have you managed to have Display use up so little battery?
Mine always has about 75% and up, at the least...
I use Autobrightness with no Mod for lower Autobrightness.
I have nothing changed.
Flashed recommended Radio.
Flashed ARHD 6.1.
Done.
As you can see some harder Battery drops, while i was playing some Games. All time WLAN on. But i used it als always and had a very nice Battery expand.
Hmm, How much time is your display turned on? as i said, this saturday after i had flashed i emptied the battery in about 5 hours with screen on 4 of those.. Feels like the screen is taking alot of battery but i guess.. I had full brightness, not auto..
I don't know exactly but i would say display was active vor 15h+.
Autosync runs every 3h.
If you freshly flashed, it will take some time to stabilize. So maybe drain it until its empty/almost empty(10%) then get a full charge. Try to reboot and watch again. If you still have problems you schould install current widget and let i generate log. where you can see how much it drain if display is off and/or phone is standby.
If I put on screen from standby and check current widget i have 3mA/5mA. So if display is off the drain is very low.

[Q] >:( phone shuts off every minute

okay so for the past weeks, i have been running the latest cyanogen rom nightly and i read about the script by puremotive that improves you battery life so i flashed it, everything was working wonderfully, noticed increased battery life but yesterday when i woke up my phone was off some how, so i turned it on and before i could even open an application it turns off. i mean like just turns off no bootloops whatsoever. When it turns off, if i have like full battery charge its drops down to 15%
so i was wondering is it my battery thats the problem or the phone?
and yes ive tried wiping everything and even flashed a different rom.

[Q] HTC DHD 4.2.2R8 drain battery so much

Hi everyone!
I'm using JellyTime 4.2.2R8 on my DHD.
It's working fast but battery drain so much.
Ex: I only view screen, scroll something. Everage 1 minute, battery degree 1-2%
Who can help optimize this problem?, thanks!

Hi,
I installed JellyTime R8 on Monday evening, and I haven't experienced such a battery drain so far, it goes down a bit faster than my stock Gingerbread+Sense ROM. I might have other stats issues (wrong "on battery" duration, charge stuck at 90%...), but no drain so far.
I am not well experienced in flashing ROMs and how to solve problems, but I have seen lots of people advising to flash the battery stats and recalibrate. But you need a few complete charge/discharge cycles to make it work properly. (But according to a few other people, it's a kind of religious belief too...)
You can also install a more precise battery stats app. I saw a more detailed message in Jellytime Dev thread (in one of the last pages). If I find it again, I let you know.
BetterBatteryStats

I cannot find again the thread/post where I saw this information, but the application some people advise to use is BetterBatteryStats.
To give you a counter example: since I flashed JellyTime R8 (Monday 20th Mai, 23h GMT+1), I fully charged my phone only twice.
The first discharge took almost a day (but I used it a lot, configuring and playing with the new features).
The second discharge started 33 hours ago and I still have 50% as we speak. Maybe the stats are wrong, but the phone is still ON after 33hours. I'll let you know how long it lasts.
I am on GSM roaming all day long, but my phone stays most of the time in standby mode.
A few things that I've done to optimize the battery life:
- remove the constant location-tracking, both GPS and 3G (especially as GPS is not working since I flashed JT R8);
- remove permanent/auto 3G connection, as I am spending all the day abroad, it is useless to keep 3G activated, without data roaming on.
Go in Settings/location and switch the toggle off.
Go in Settings, expand Wireless and Networks (Plus), then Mobile Networks and untick the first box (my ROM is in french so I am not 100% sure of the translation, it might be something like Activate Data)

Thanks Matth59 !
I toggled off some setting in phone (GPS, MobileData, effect screen, animation, turn off notification some app...)
But but it does not improve the problem of battery.
I charged full battery, after 24minutes
Saw status of battery on 24m19s, (95%)
Screen 70% (I set bright of screen about 20-30%)
Cell standby 6%
Android system 5%
Phone idle 5%
Wifi 3%
Facebook 3%
Android OS 2%
Media server 2%

And how long does it usually take for it to be discharged?
The second time I charged it, it said that charge was complete and stopped charging at 90%, and I got the impression that it reached that level quite fast. But the device is still on, after 38 hours.
I hope somebody with more experience in that field can give you a better advice or more information, than just flashing the battery stats and recalibrate it.
After one week of using R8, this is how battery is going for me.
On standby, it can last as long as it used to with the stock Sense + Gingerbread ROM (or even a bit more, but maybe because I haven't reinstalled all my apps).
When using the phone, battery life is going down quite fast, and I am not sure if it can last more than 1 day of normal use (3g, mails, messages, calls...).
The most battery consuming task is the screen. It makes me wonder if it could be related to the feature that was introduced by Google since JellyBean 4.1: Project Butter, which makes everything smooth in Android.

new battery and having the same problems before the old one died.

Hi all,
I got a new battery a week ago, because my phone didn't turn on or charged anymore.
But my battery keeps draining. I lose around 25% in idle at night time. And around 3% every 5 minutes when I use it.
I used gsam for a few days now to see iff there are any applications that are causing the drain. So far I can't discover any.
Also when I'm using my phone the side of the power button gets hotter then the rest of my phone. While the battery and cpu both are under 40 C.
I do have android 10 and 2.1 ui from devbase rom with soldier 6.0 clean installed, tried other roms aswell, so maybe I should get back to android pie?
I also started using ex kernel with the standerd underclock option you can choose while flashing this helps a bit.
Hopefully somebody can help me out.
Some gsam data
I have the same. I used different roms and kernels, all the same. I turn on airplane mode for the night. it helps a bit.

Thank you, this reassures me that It's just a coincidence that my battery died, and that the behavior of my phone at the moment doesn't mean it would happen again.

I do notice, that gsam says that that I am using wifi all the time. And it shows that battery usage is high when this happens.
The only thing is that I never use wifi anywhere..
I don't know if this is something to go on or just normal behavior?
