Battery Drain - Standby Mode

I'm on Darkyy's v8.0 ROM and without a SIM card. Since I'm without a SIM card the phones time without signal is 100%. My phones standy by time is also equal to the up time of the phone. Is this normal...? My battery is draining unusually fast. I've checked OSmonitor and I get LOTS of errors, but I'm not sure what causes them.

I found the same with that rom suggest use another rom as it fixed my battery drain .

Which rom are you using?

Why not put it in aeroplane mode?

Not sure about other non battery errors:
As for the Battery problem on v8.0
You can either upgrade to V9.1 and/or try the following which is found in their website
(Search for Darky ROM Calibrate Battery)
Calibrating Battery with Darky's ROM:
1. Use your phone until the phone switches itself off (battery empty)
2. Switch on once more to make sure battery really is 0% (it will then immediately switch off once more)
3. Now, keep switched off (!), plug in charger & leave in charging until 100%
4. When battery is full, switch the phone on, unplug & check if the batter immediately drops 1 or 2 %
5. If battery immediately drops, plug in charger once more (while running phone) & let it charge completely
6. Once charging to 100% is done, keep charger plugged in & Reboot into Recovery Mode
7. in Recovery Mode go to: advanced --> Wipe Battery Stats --> Yes-Wipe Battery Stats
8. When done: Go To --> reboot system now
9. Once system has rebooted, unplug charger

Try Simply Galaxy 2.4.1 with ROM JS5, i can run 1.5 day with moderate use of Wifi, browsing and email

Yeah I've had the same experience after upgrading to 9.x, I tried all the usual recalibration tricks and even bought a new battery. i'll give another rom a shot to see if battery life returns to normal.

I highly recommend Juwe's 1.5.5, fast, stable and great battery life.
Shouldn't this thread be in the Q&A section?

Use the app "Battery Mix" available in the Market too identify which apps/services consume an --unwanted-- x amount of power.

or the new Darky Rom 9.5

Q: Xoom wont recognize battery stats

Just yesterday my xoom stopped recognizing my battery stats. Reads 0%. It charges but won't give me an actual reading of my battery. Installed circle battery widget and still gave me a 0 reading...

if you are rooted and have clockworkmod installed you could try wiping battery stats within the clockworkmod settings?

Thanks for letting me know. Forgot to say in the OP that I'm not rooted. I've been shying away since due to the wiping of the device. Might have to do that anyway for a factory reset, to see if that might help.

i have had a look around and it seems you need to have root access - you could try this
1. Run down your device’s battery until it turns itself off
2. Turn it back on and wait for it to turn off again; this may be straight away of after a few minutes
3. Remove the battery for at least 20 seconds
4. Replace the battery and charge until full and then for at least another hour – while the device is off
5. Delete you batterystats.bin file using one of 3 methods (requires root): Terminal Emulator – type su then press enter, next type ‘rm /data/system/batterystats.bin’ (without quotes). Using a Battery Calibration App (from market) – there are many choices available, they just delete your batterystats.bin file. In market, search for battery calibration. Make sure to read review and provided info in case of device incompatibilities. Manually – if for any reason the previous two methods didn’t work you may want to try deleting the file manually. Using a file manager with root access (such as Root Explorer) navigate to ‘data/system/batterystats.bin’. Delete ‘batterystats.bin’
6. Your device will now creates itself a new batterystats.bin file with a correct 100% battery reading
7. Run down the battery until it turns itself off
8. Turn on the device and charge for at least 8 hours
9. Unplug the device, turn off and charge for another hour
10. Unplug the device, turn on and wait for 2 mins
11. Turn off and charge for another hour
12. Use the device as normal

or just root and install cwm and wipe battery stats - hope this helps

No Go Rooted this weekend and still 0% battery. Wiped stats with CWM and deleted the bin file, tried different calibration tools. Still same problem. Charges though, and the indicator light changes once fully charged, but still flying blind...

[Q] Battery Problem Or Cache Problem ??

My Nexus 5 is randomly shut down not rebooting even if the battery percentage over 90% , and if i try to start it immediately after that the system try to rebuild cache again by optimizing apps one by one "Take 10 minutes or more" and the phone always shutdown before completing the optimization plus the battery dropped to 0%, but if i connect the phone to power source then try to start it, it will start normally but the battery percentage drop by 25-50%
i try all this following methods without any result
Factory Reset
Clear Cache by default Recovery and CMW recovery
Re-flashing stock image throw adb-command
Downgrade to Android 4.4 and then switch between Dalvik and ART
Flashing CM-Based Roms
Flashing different kernels
Lock or relcok bootloader
Encrypt and Decrypt the system
Secured an unsecured lock screen
safe mode
all of the above tries failed to stop this issues, and because my Nexus 5 is out of warranty I need to know is this battery issue? and if i replace it this problem will be fixed or this is a deeper problem with cache partition and need professional to fix it
Note : he phone never shut down if it connected to any external power

The issue is well known and widely reported. There's a Google Product Forums thread about it here
https://productforums.google.com/fo...urce=footer#!topic/nexus/IJSOuc7gw0w[326-350]
I have it as well, exactly as you describe it. In my case battery replacement seems to have solved the problem. The phone runs perfectly now.

it's battery issue
I replace the battery and the phone till now run perfectly

Not charging past 70%?

Hi, I have a galaxy s6 Sm-g920X (live demo unit). It auto updated to version 5.1.1 and since that time it isn't charging past 70% help!
Furthermore, if I turn it off and plug it in, it will turn on automatically! I can't make it stay off when plugged in.
Side question: How can I disable annoying low battery power notification when it reaches 15%?

Hi, the battery not charging fully has happened with a few people online and the fix has been similar. Wipe the Cache through recovery mode options, then let the battery run to the point where the phone shuts off. Then try charging and see if it goes past 70%
Not sure about the other problems hopefully someone can help you with them

Will wiping cache affect my apps, like control settings for Modern Combat 5 etc?
Thanks!
I should also have noted that I am not using an original charger. Could that damage the phone/battery?

As far I know nope, wiping cache is different from clearing individual app caches, and it won't lead to any loss of personal data or settings (including app setting)
And nope all charger leads that fit and charge your phone should be efficient and not cause any damage, I've not always used an S6 lead for my Galaxy

Wiping cache did NOT solve the problem.
Any other solutions?

Help!!

Wiping cache and dalvik... then let de battery go to 0% and turn of the Fino alone, the charge and see what happens.

Hello, I have the same problem with galaxy s6 g920x. How do I wipe Dalvik?
what is Fino?
thank you

Download a program called "Battery Calibrator"
You may need root, this should fix your problem (Just run it, and drain your battery normally)

Did it work?

How to reset battery stats on phone with no root ? I have a few options Help Please

How to reset battery stats on phone with no root ? I have a few options Help Please
Hi , I have posted my query in the oneplus 2 forum twice , but sadly no reply , But I have a oneplus 2 phone , in general it is working great.........BUT my battery stats are not reporting correctly.
Okay I have tried the fully discharge , fully recharge method etc etc......
So I thought perhaps fully charge the phone to 100 percent , then do a full reset ( But Will this reset my battery stats ??)
Or I have two options when turning the phone on with power pressed and volume down.....
1) Wipe data
2) Wipe cache
Ideally I do not want to fully reset my phone it is set up just nice and how I like it.....BUT the battery thing is niggling me too much...
I know the battery is not faulty because if I follow this procedure the battery is great all day....fully charge , then let it run down say a few percent
