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:

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
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
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
Hi everyone, I am new to this forum, having been made aware of it by a member of the Tom's Hardware forum.
I bought a T-Mobile LG Leon one month ago. For most of that time, I was getting 3-4 days of battery life with fairly light use, WIFI on, Bluetooth on some of the time. In the last few days the battery life has decreased significantly, so I decided to keep a log of the charge status. For this test, I turned off WIFI, Bluetooth, and Sync. Screen brightness is set to 48%, and screen timeout is 30 seconds. As you can see from the log below (sorry about the formatting, copied from an Excel spreadsheet), I am now getting just over a day's worth of battery life, with the phone being turned off overnight. During this test, I had no applications running. The only application that I recently downloaded from the Google Play store that I thought may be eating up the battery life is "Friend Locator", so I force stopped it for the duration of this test.

Please let me know if additional information is needed, or whether I posted this in the right place (I couldn't seem to determine how to post in a specific section). Since I am pretty new to this phone, is there an app or setting that will tell me what is using the battery?
Thank you in advance for any advice.
It seems that you need to clear the cache of the device.
Goto settings. Open storage and there clear the catch by clicking on it.
I am sure that this will help to restore not fulley but partial battery life.
And you may also try factory reseting the device.
That will help too.
The problem.can also be a system.update

OK, I did clear the cache, it contained about 73MB. At this point I do not want to do a factory restore, as I have downloaded and installed several apps which I will be using. Also, I turned off the "Location" service, having read on another thread here that Location can use a lot of battery power. It is on the charger now, I will monitor the battery status once 100% charged. Thank you for the response.
Ok then use es file explorer to make backup apk files of apps you downloaded from.play store and install the on any device when ever you want to.
Just for knowledge
Hello, I use Sony Xperia Z1 Compact and it's less than 2 years old. Phone battery "dies" few times a day, it can be around 60% (like it was today) and then it fastly goes to 0% and turns off. I put it on a charger, reboot it and the battery life goes back to 74% sometimes even 93% (while before turning off and instant drain it was around 60-70%). It wouldn't be so bad if I could do that without a charger, but this happened to me three times only today and it's really frustrating when you actually need the phone.
I always have STAMINA mode on and I always make sure to go to settings and turn off all the apps I don't currently use, also the thing that's draining the battery the most is Android system. I don't have a clue what to do and I couldn't find an answer anywhere online so I'm trying this way. Thank you in advance!
Below are screenshots were taken on the same day, one was taken at 07.50 pm when the battery was at 18% (after it went to 0% I put it on a charger for a bit) and 6 minutes after that I rebooted it and it went to 91%. At 08.20 pm while on the charger, it went to 97% and the data about battery usage was not available. As you can see, android system and screen are using the most battery (in "normal" occasions system is still on top while the screen is usually few percents below the usage of the system).
I do have some tips.
Do clean the cache of the device.
Uninstall any battery saver app.
Use any battery callibration apps when battery is 100% and after callibration uninstall the app.

Thanks for your reply but unfortunately it did not solve any problem.
If thats the Case then you have one way to follow.
1- backup all apps and data using es file explorer on the external sd card.
2- factory reset device.
3- set your device again.
If that works then great. But if it dosent then
1- root the device
2- download stock rom for your device.
3- factory reset device and flash stock rom as per their guide.
That will help for sure. But if by chance that also didnt worked. Then i am sorry to say the battery is out of its limits. And there can be other hardware damages too
