Hi i need to somewhow calibrate my new battery
I have an app called "battery doctor" and it says that my fully charged stock battery has 350hours standby. sounds good.
The same app says that my 2400mah battery has 350hours standby. so it seems that the phone or at least the app has not realised the increase in capacity.
any apps that can support this new battery? I tried the battery calibration thing:
1: charge phone when on,
2: turn off phone and charge again (but after like a few seconds the led goes green)
3: turn of phone, then after 2 mins, turn off phone
4: charge off again (led is only on for a few seconds before turning green again)
where have i gone wrong?
anybody?
You can reset the phones battery knowledge by removing the batterystats file at /data/system/batterystats.bin
So do your calibration thing, and delete the file.
i have already deleted the app...
Can anyone confirm that if i delete the "Said File" /data/system/batterystats.bin ,
the phone will be recallibrated and boot up?
im afraid of boot loops
i can confirm this for the galaxy s on 2.2.1

Hi!
I installed samdroid kitchen mod, and I noticed, that the phone turns off, when battery level turns yellow (i'm not sure about percentage, but I think it's more than 5%), however, with stock 2.1-update1, battery could drop down to empty-red-crossed (about 2%?), and phone would still be turned on, and it still had about 15minutes of listening to music life.
With samdroid, phone turns off safely, when with stock it dies. I know it is safer the samdroid way, but I would really like to use my phone for few extra minutes...
Is there any way to change these values, when does phone display "low battery warning" and when does it turn off?
You should download a battery widget. The values given by the icon on top aren't accurate.
I use samdroidmod, but don't experience the same problems..
You can try flashing another kernel with a different battery driver, like qbanin's kernel.
Download coolS from market it will slow down CPU to half speed if not need performance and resumes it if needed, it lifes up your battery.
if not intall from recovery LK2.10.beta1, then convert your file systems from rfs to (EXT2 for system and cache then EXT4 for Data), reboot and apply samdroid turbo you'll have a circular battery with 1% and boost up performance.
test it, it's great.
Hi, I have rooted my Galaxy Chat B5330L, and afted that the battery drain quickly... as an example, yestarday at night I charged to a 100%, then I put in airplane mode and got to sleep, I wake up after 4.5 hours (6.30am) and it has 93% (in airplane mode). Then I turned on the signal as usually, and without using the phone I got 80% (9am) in one hour. Now its 11.46am it's in 65%.
By now in the menu Battery (settings - battery) I got SO android 43%, Screen 19%... etc.
One thing that I don't underestand is that in the same menu, my phone have "SO android" (43%) and "Sistema Android" 7% ¿?
I've also tried to do this ...//gs3.wonderhowto.com/how-to/reduce-battery-drain-your-samsung-galaxy-s3-by-fixing-android-system-usage-0142361/
that is rename a file with a root explorer, but I don't have "gsiff_daemon" file... I have "dbus-deamon", but I don't know if it has the same purpouse.
Soory for my English.
Thank you very much and have a good day.
Omar.
I have a Vodafone Smart 4 Power, and the phone is awesome, but this phone have a big issue.
The battery percentage and icont remains constant and after drain in 15 seconds.
For example battery percent is 35% and i use phone 2 hours. After battery it show 35%, but in 20-35 seconds drain to 0. (35,34,33,32...0 in 35 seconds, lose 1% every second)
I think is a software problem, because if i reboot phone (power off not restart), it show correct battery percentage.
Is an solution for this?
i search on google and xda and i found this:
http://forum.xda-developers.com/q1010i/help/help-battery-remains-constant-drains-to-t2841579
i try to remove batterystats.bin, but not working. also i have install betterbatterysts and gsma battery + root.
i dont try any modul in xposed, because i dont have xposed.
U have any ideea how i can solve this?
I recently noticed after the latest update excessive battery drain as seen in screenshots posted below. I have tried a factory reset and then unlocked bootloader to root and added greenify to try help save my battery. Does anyone have any tips on what else to try?
Have you tried to figure out what the Miscellaneous drain is? At least on my tablet I don't have that category in battery usage.

Miscellaneous is android figuring out the rest of the battery stats, it's normal for new devices.

If by "new" you mean recently flashed/factory restored, then I'm not sure what to say. Even after flashing a recovery image I've never noticed that category. The only reason why I asked was because I assumed that was what you were referencing as being excessive.
If you were referencing the 24+ hour battery life graph shown in your screenshots, then that seems about right. Unfortunately the tablet has never been known to have stellar battery life unless it's on battery saver 24/7.

Seems about right?! He had 7min 2sec screen on time. If thats "about right" to you... you need to RMA your tablet.
Clearly whatever "Miscellaneous" is, is his issue.

Ok, so I noticed the very same thing when I got my Shield, I haven't rooted (I had on KitKat to restore some backups, then didn't do it again in Lollipop yet). I contacted Nvidia's service via livechat and got this answer. It did some considerable difference, although I still think it's draining a little too fast, but my old tablet had a pretty strong battery so I was just spoiled by it it seems >.<
So here it goes:
Nvidia Shield Callibration: (this takes a while)
You will have to calibrate the battery for just one time and observe the device battery backup for 2-3days to see the changes.
1: Drain your Shield tablet battery by using it normally until it turns off by itself.
2: Power-on your Shield tablet, if it wakes up and if you see some power left, follow step 1.
3: If Shield tablet is now drained to the point it can't wake up, set the device to charge for 7-8 hours.
The device should remain off when you set it for charging here.
4: Unplug the charger after 7-8hours, power on and wait for the battery charge to drop down to 90-95%.
5: Once the device battery drops down to 90-95%, plug in the charger and charge for one complete hour.
6: Unplug the charger once the device is fully charged.
7: Go to Shield settings > Shield power control > Apps> select optimize all option.
8: Go to Shield settings > Shield power control > system>
• Set the brightness to auto.
• Change the sleep option to 2 minutes of inactivity instead of default 10 minutes inactivity.
• Change the processor mode to either optimized or Battery savings.
• Check the WiFi optimization on.
Observe the device performance and report to us if you are still facing issue with the battery backup..
And then they gave me some tips for better battery life in general, I follow them (mostly) and my battery seems to hold on decently:
1: Always use the Shield tablet charger and not the computer USB ports or any other charger as the power specifications vary from the device to device.
2: In case if the charger is missing, use the back port of the desktop computer to charge the device instead of front port.
3: Always remember to exit the application instead of tapping the home button which will continue to run the application in the background.
4: Restart your Shield tablet at least once in a week. This will refresh the device making it work faster and efficient.
5: Connect the charger only when the battery comes down to 15% and unplug the charger only when it reaches 90% or above. This will reduce the number of charge cycles which will make battery last longer.
6: Use a third party app manager like Clean Master and free the memory at-least once a day to keep the device running faster.
To notice if the battery is fully/optimally charged when the device is off, look for the led indicator next to the charging port. It should be green, indicating it is fully/optimally charged
Does your android phone battery instantly drop down to 10% or less in a span of 2 to 3mins?
I found that it is the batterystats.bin log file which gets corrupt due to intense usage sessions. You can reset that file using any battery calibration app. Its safe and works 100%
Search in google play store for battery calibration apps. They all do the same job.
Procedure:- 1) Plugin your android phone and full charge till 100%
2) Click the button in the app to start calibration.
3) Unplug your phone and let it discharge normally.
4) If it does not charge at all, try calibrating it first and then charging.
If this method works for you drop a comment below. :angel:
