[Q] battery callibration

I installed Batery Callibration in my Galaxy Note .. Love this app...... Increase so much my life battery
One question: How often I Calibrate My Battery??

1. After flash or update ROM.
2. When replace or pull out & put in battery for whatever reasons.
3. I do calibration about once a week.
I always drain battery till it is 1% before plug in charger after hit the calibration button.
Battery time is acceptable to me...15+ hrs with normal use (stock ICS rooted).

Thank you very much for the tips. I Have Rocket Room V07 and Speedmod kernel 3.3. With 3g and Wifi turn on all day, my battery last 24 hs.....Very good for me

which battery calibration app?

A question for both of you and anyone else who's using such a tool: which battery calibration app do you use? Any views on how good (or not) these apps are?
Cheers

I use battery monitor widget pro, very effective and good widget also.

Never. That app does NOTHING. You have fallen victim to the placebo effect.
Wiping battery stats does NOTHING on any Android device other than change the behavior of Settings->Battery. It does nothing with regards to fuel gauge calibration.
The fuel gauge chipset in our device does not require calibration and calibration techniques cannot be applied to it. (With one exception - resetting it after a reboot on low battery can have a temporary positive effect - but you can just wait a few hours for it to converge.)

As stated above - they are 100% useless and worthless on our device and any other Samsung Galaxy S1/S2 family device.

To enthropy512, thank you very much for your hardwork for us here in xda. How about a tread that says, after a battery full, you take out the battery for 3 mins then put it back again.

Battery Calibration, try following the procedure stated therein and verify by yourself if it works.
At least you have nothing to lose but very poor battery performance.
You guys should have ever heard of an alternative battery product named MUGEN that selling original and extra sized batteries world wide including range of Galaxy batteries. They also supply a battery calibration app on Play Store regardless phone models but it's for rooted phone only. If this app does nothing they wouldn't bother wasting their time developing it.
Another thing is to investigate what apps or services prevent your phone from going into deep sleep, also try freezing apps or services you aren't using.
Those are my tricks for having battery performance improved.

Hi can i have the link for the calibration app ???

Search battery calibration on google play...its free

Your phone had to be root to use battery calibration

i dont trust any battery callibration app or battery power saving app
i only used cpu spy and betterbatterystats
my point is check ur device, does it goes to deepsleep everytime screen turned off. if it doesnt check using bbs what apps making ur device turned on/wake ur device. im very satisfied with this method. 1x full charge for 24 hr for my daily use and only 24 % battery drained for 24 hr if u didnt use ur device at all(standby)

[Q] MT4G Battery problems

Hi all,
I have a MT4G running cm10.1. Prior to this, I was running toasted marshmallow's latest build.
Over the last week or so, I've been having some real problems with the phone. While in my pocket, it will discharge rapidly and switch itself off within a couple of hours of being off the charger. Other times, it will read a high battery percentage (80-90%) but will switch itself off randomly. When I go to switch it back on, the battery percentage reads 1%, and it switches off again soon after. If I try to switch it on again, it doesn't make it through the load process before switching off. It seems like the battery is completely discharged.
But (and here's the weird part): if I stick it on the charger, give it a few minutes, then switch it back on, the battery percentage will read 58% (both times I've checked this, it was 58%), and will then charge from there. It stayed on for the rest of the day when I took it off the charger (at 65% charge).
Edit: I though this might be a battery contact/connection problem, but shaking the phone / playing with the battery cover doesn't seem to bring it on. To be safe, I used a pencil eraser on the contacts and have a small piece of card in between the battery cover and the battery, to give more support to the battery. No reboots so far, but it's only been an hour or so.
So:
- is my battery dead, and can this be fixed by a replacement?
- is battery calibration needed (I know this is a controversial question; the consensus seems to be it does nothing)
- Is this more likely a hardware problem with the phone? I have noticed that the charger microusb cable does seem a looser fit compared with before, but since the battery was still charging I figured it wasn't a problem
Thanks for any help troubleshooting this!

Sounds like your battery is done...replacements are cheap...

What he^^ said.
Anker batteries are good and very inexpensive. Also, "calibration" does nothing. Just flash ROMs on a full charge and call it good.

Try to constantly check your what things are draining your battery, sometimes it could be the phone's data or it could be the sleep(idle) state of the phone, it could be many things. I tend to be always aware, check and read all the possible outcomes for the battery drain. For me is usually maintaining the data on my phone turn ON.

I have been having the same issue with my 10.1 ROM. It's not that old of a battery either so I don't think that it is dead; is there any other advice other than purchasing a new battery?

Switch ROMs and compare battery life? Also, check out Better Battery Stats. It can help you track down what causes drain.

This is the third ROM (starting from an ICS ROM) and the battery life is the same so I know it's not the ROM. Thanks for the app recommendation. I am afraid that I might have a defective battery.

As it turns out my battery has now started to leak and swell. I am going to purchase a new Anker battery. Thanks for all the assistance.

How long is a bit of string?
What is the meaning of life?
Your question is the same as the ones above - who knows
most likely you have an app that is draining the battery - for example kik messenger or bbm or some other app that is keeping the phone awake or just draining battery
use an app on the playstore that will tell you app battery usage

If you have a lot of running apps in the background dont expect your battery to last longer.. Uninstall apps you dont use and keep your phone clean

[Q] Galaxy S4 Battery (I-9500) drains out quickly while playing Candy Crush

Hi,
I saw many folks are facing similar problems, but my problem is little different. Now a days whenever I play Candy Crush my S4's battery drains out very quickly i.e. 60-70% in the span of 5 - 10 minutes, also it gets charged up with equally fast (about 80 % in 10 min). My phone is just 3 months old...earlier there was no such problem. I haven't installed any new apps in between. Is it the problem with the battery or with the handset?
Any help will be greatly appreciated!!
Thanks

The battery drain in almost time cause of software problems
But charging too fast Im saying it could problem with the battery it self
Try to charge your phone with original charger

switch off your phone. charge till 100% go into recovery and give a factory data reset! your problem solved.

I don't think this will work.
My guess is you have a faulty battery. That happens. Get a new one.

lennyz1988 I respect you but here i think there is a fault in battery caliberation. Your advice is also true but why not try a factory reset before purchasing a new one?

have you tried looking at your battery on settings ? see if what apps consumes most of your battery

It's because from what I remember, battery callibration is not regulated at rom level. It's a chip inside the battery.
For example:
With the old HTC Desire you could wipe battery stats in the recovery.
For the Samsung Galaxy S2 this didn't have any effect because the chip inside the battery regulated the calibration.
From what I remember it's the same for the S4. If the calibration does not work (eg charging to 100%, taking the battery out, putting it back in, recharge again till 100%) then his battery is faulty. So unless he messed his rom up seriously, no wipe or other rom will help. His OS just reads the data from the chip.

[Q] How to fix fake battery states on almost all roms?

When i switch another rom, every time my battery draining is terrible so i think this is the battery states fault.
Anyone tell me what is the better way to fix this issue?

What do you mean?
It's normal for a rom to use more battery the first time you use it. Besides that there is no such thing as a fake battery state.

Ok sir
I use amlify, freenify, and boot manager but...
After 3 days using this rom or every CM based rom i lost 25% of battery on 7 hour without using my device.
Sorry for my bad english.

battery life will decrease when not in use, this happens to ALL phones or electrical devices that use a battery

well obviously everything that is not plugged-in , on the electricity needs power to run, but i think you lost the point of his message,
i think he means that 25% is a lot, for a phone in no use.

I lose more with data on. I think it's normal result for 7 hours.

Custom ROMs need a "settling in" period where the software polls the hardware for its capabilities. The OP may simply be impatient and expecting instant benefits from the ROM without giving it a chance to adjust itself to the hardware. 25% in 7 hours is typical for someone not using Greenify, but it's arguably high for someone using that app. If the OP isn't being impatient, it makes me wonder how old the OP's battery is, since a new battery shouldn't be having this much drain.
The OP would greatly benefit from updating to an Android 6 ROM. In situations where the phone is simply sitting there, Doze kicks Greenify's a** all over the park.
