'Hey there,
I am running Minco V6 with Franco Kernel, and before that I was using rasbeanjelly with trinity. All of a sudden I noticed that The battery Icon was showing as if I was always charging the phone, same thing in the battery stats, it shows as if I was always charging the phone. So far this has not represented any major issues, but it is annoying when the battery goes below 15 % and it starts sending me low battery alerts. The battery icon switches from charging to discharging every 2 seconds son the alert is flashing all the time when battery is below 15%.
I try reseting the battery stats, flashing different ROMS and kernels, fixing permitions but no success so far.
Any Ideas??
Regards

Installed Leedroid froyo over stock rom.
Replaced the radio with recommended one.
Installed the kernel.
SET CPU= Smartass
Problem: 8-9 hours standby time. No wifi. Phone on 3g network.
New problem: Phone's screen is not getting off automatically since i updated the kernel.
Please help. It is driving me nuts. If I use gtalk for about 2 hours, battery is drained off in 5 hours.
Its a brand new phone and battery had a days back up on stock rom with conservative usage.
Was your battery at 100% when you flashed the radio? I had to recalibrate my battery after flashing a radio on my standard Desire when the battery was at about 50% as I was only getting about 6 hours standby.

Did that. The only problem am facing in this is when I achieve a green light and 100% with the phone switched on, the moment I shutdown/power off the phone to charge further, the CWM recovery console comes up with a backlight and the orange battery indicator never turns green (even after 1-2 hours).
So at orange indication only I wiped battery stats, and thereafter there was no improvement in battery life.
I would advice to wipe all (backup first of course), install the ROM again, monitor the drain with nothing installed (except battery monitor widget).
I usually do a test in flight mode (target=2mA)
then with phone ON (data ON/OFF doesn't change a lot for me) (target 3-4mA)
!!! disable all autosync !!!
If you have the same values I will say that it's ok.
Then add one by one your kernel, account sync, appli an monitor the drain (at each step).
You will find what is draining your phone.
Do not forget that the drain is subjectif. In GPS I have often more than 300mA drain!
Where do I download the battery monitor widget?
you can download it at HTC widgets for battery monitoring.
Current drain is at 250-300. That too in standby. Gps off. Wifi off. Don't know what is happening
Airplane mode it is 134
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.

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.
Hello,
I have a very annoying issue with my battery percentage. Typical scenario:
I unplug my phone at 100% after loading it overnight and perform some basic tasks, like for example reading news with Flipboard for a couple of minutes. My percentage already goes down to about 75% to 82% in about 10 minutes. Then I don't use it intensively, only to check the time or messages, so the percentage stays at almost the same amount for hours. When gaming, or performing other more intensive tasks, my percentage almost drops 1 to 2 percent/minute. I get "battery low" warnings at 14% and 4% and then it goes down all the way to 1%. Now I can just continue using my phone like before, for example for gaming, web browsing, for something between 40 minutes and 3 hours.
The issue is obvious: my battery percentage is not calibrated correctly. This has been occuring since more than half a year now. I had many different roms over the years, I can't blame it on one particular one.
Now, I read about a lot of ways to calibrate your phone, so the percentage is accurate again. I have tried a lot one of them. None had any effect. I tried the following:
- wiping battery stats (multiple times)
- completely unloading my phone (restarting it multiple times, boot into bootloader and waited until it just turned off by itself and won't turn on again) and then reloading it (via charger) without interruptions (everything multiple times)
- using the app "Battery Calibration" (deleting batterystats.bin)
- using the app "Battery Monitor Widget" (waited until it shows 0 mAh, then wiping battery stats
- some battery saver app
I also switched batteries with a phone that was purchased at almost the same date as mine (09/2011) and has not been modded in any way. My phone currently runs Jellytime 4.2 R11. I updated it this week, and also wiped battery stats during the installation process at 100% charge.
Any suggestions? Any help is appreciated! Thank you in advance

Easy!
Get a new QUALITY battery.
But maybe that was to obvious for others to respond.
Recently my N7(2013) will shut itself down when the battery is low (about 10%) without any warnings, not even the "Shutting Down" dialog that it should show whenever it shuts downs (except for the usual low batt warning when it reaches 15%). After the shutdown, I cant even turn it back on not even the screen, nor the low batt (waiting for charger) screen is showing up until I plug it into a power source the it will show the charging screen and then I can turn it on again.
Its been a few times now, not sure its a hardware or software problem though. It shouldnt shut down when it still has 10% in it right?
Attached is the screenshot of the Battery Usage that shows the battery level shots down to 0% immediately from 10%.

Are you using a battery monitoring program (battery doctor, better battery stats, etc)? If so, look in their settings, to see if they are set to shut down @ 10%...

Nah I don't trust these apps so I don't use them. Moreover I'm did not root it so even if I use them they shouldnt have the permission to shut it down
Simple fix
It is an issue I have suffered with a couple of times and it appears we are not alone. It seems that the battery calibration is out of whack. When you charge your nexus up does it stay at 100% for quite a while? I
tried factory data resets amongst other things and nothing worked. I stumbled across a thread with a really simple fix. Turn your tablet off for 2 hours. Then turn it on again. Mine miraculously lost 26% of battery in that time (from 100% where it had been for 8 hours down to 74%). Then it started to use the battery at a normal rate. Working fine now.
I've tried RE calibrating the battery but keeps showing two different battery percentage whenever I turn it off .plus I can't tell if my phone charging because It goes up & down anyway to fix this to
