[Q] battery immediately drops down after.....

i've read about similar topics, but i think i did not found answers...
i've been aware that x2's battery drains fast. i had lots of bad experience with this problem so i decided to buy a new spare battery. to describe my problem, here is the scenario.
1. i fully charge my new battery
2. i remove my new battery to charge my old battery
3. after my old battery is full, i remove it to use my new battery (which was fully charged 4 hours ago)
4. after turning on the phone, it reports (immediately) BATTERY IS LOW.
5. i scratch my head why, replace it with the old battery instead, turn it on, and reports LOW BATTERY also.
i think this is a phone problem and not a battery problem. what do you think? why do i also encounter same problem with my brand new battery?
please help. thank you...
this is a new problem i encountered after reformatting my phone...

did u try flash to another firmware?
I had similiar problem as u when was using firmware Genenic_sg, flashed to Generic_en then its gone

by trial and error...
by trial and error, i found the solution... (once my main battery runs out of life, i do this steps...)
i let my spare battery stay on the phone for about 10 seconds before turning it on... (something like at least, the phone will recognize the life of the newly inserted battery)...
there are occasional times however, when the battery meter will still say low battery life even if i already had the battery stay before turning it on... so what i do is just turn it off again, remove the battery for few seconds, reinsert it immediatelt, and turn my phone again... and voila! it's finally recognized as 100%.

When you recalibrate your battery, it takes a few life cycles for the battery to stabilize and for Android to get an accurate reading. First life cycle is alway short. Of course, don't play with ROMs so much it may damage your phones read only memory.
I will post my battery life soon, I'm still waiting for the battery to deplete, I haven't recharged my phone in 4 days now after I calibrated my battery.

Wow 4days is huge,iam getting hardly 1day battery after calibrating yesterday....
Actually i removed my phone before getting the 100% notification....
So should i wait for battery to improve???
By the way,when did you calibrate???
Should i calibrate again????
If this wont work i will try terminal emulator method...
So in this method do we need to charge 100% or discharge completely??
Some precautions or just write those commands at any point of charge???
Iam wondering how to thank from the xda app
Thnx to both of u

Same problem here.
Battery drained from 100% to 60% in 3 hours, then to 15% after 5 hours. phone super hot! Widget showed temp 42°C !
Not even used the phone for more than 15 min! REALLY!
Then calibrated before 3 days, now a max of 1 day battery backup only.
Plz help.
And 1 life cycle means I must let the phone charge 100% then let it discharge till it's switched off.
And I should repeat the cycle.correct me if I am wrong.
And I have the habit of not charging to 100% in a single charge session, 2-3 breaks, should I change it?

clarkkov said:
If your phone is hot without you using it, something is running in the background, that shouldn't. Which ROM are you using and which tweaks/fixes have you applied?
One battery life cycle means battery drain from 100% (fully charged) to 1% (fully discharged). Your phone does not have to turn itself off, but make sure it is at 1% when you begin to charge it again. This is important only for a few cycles after calibration, afterwards you are free to charge it as you wish, but while calibrating it's highly recommended that you don't interrupt the charging process (4Hrs).

I am using rooted jpd from samfirmware, no fixes except sdcard speed fix, previously it used to give a good battery backup.
And apps do run in background.
Should I set autokill level to high in task killer?
And I will take care of charging.
Thanks for support.

on DDJP2.. getting a horrible backup since i have updated thru KIES. generally on jg6 used to get almost 1.5 days which has come down to 12-16 hours now. trying to calibrate my battery with app 'battery calibration'.. calibrated once.. but still no change. read somewhr that we get the same backup for first few times even after calibrating.. but to get sure i am writing down my process.. plz chk if m doing right or not ..
1. plug in phone with charger
2. wait till 100%.
3. press battery calibration or delete batterystat.bin with the help of root explorer.
4. unplug charger and use it till it discharges completely.
5. charge again to 100%.
plzzzz chk and tell.

plzz someone reply.

I have a question about batery drain. Apps on backgroung are drainning lot of batery? May i have to stop them always?

Yes.
You need to be aware that wireless services are draining the battery the most. If you are not using 3G - switch it off, same with BT and WIFI. Widgets that update frequently also drain the battery fast, background data, auto sync services/features are battery killers, too.

Thanx for the reply.. i have calibrated once more.. but already showing 80% after hardly 2 hrs.. no clue whats going on... ppl with JP2 shud come up with thr battery backup to get confirmed.

and last thing am waiting for is that someone said .. battery life is worse for first few cycles after the calibration... thats the last hope... :'(

Thx for the aswer, i thought that all the background data are drain lot of battery. I'll try to calibrate and switch off all the thing i can and see if my battery lives more time

Hey there,
scince I use BatteryLeftWidget, I can see that my battery voltage only reches 4171mVolt.
So, batterystat.bin delete doesnt help, so anyone an idea where to put the 4200mV ?

Battery drains very fast

Looking for some insight on battery drain.
Recently my phone updated and I lost WiFi .
My warranty just expired so I decided to root and go custom rom.
First I installed exodus 5.1.1 heavy battery drain very slow charge
Tried another now on blisspop 5.1.1 heavy battery drain better charging
Changed kernel to sgs5 ktoonsez kernel
Charges as fast as when I bought it maybe a little slower
Battery drain better but still fast
Added ktweaker and tried most conservative setting
Still drains way too fast
2 hours of web pages and it needs a charge.
I used to get a full day out of it.
Screen at minimum nothing running really.
Any ideas
Greatly appreciate any help.
Thanks
Andy

Try download greenify app and powernap. The two are fantastic apps to make you battery friendly

After a rom change and after this long time using your phone you have to calibrate your battery:
1. Install this app (you need root): https://play.google.com/store/apps/details?id=com.nema.batterycalibration
2. Charge to 100%, let the charge cable plugged in and wait 30 minutes.
3. Open the app, give root permissions if the app asks you and click the "Calibrate now" button
4. Remove the charging cable from your device and use your phone normally. During this time, don't plug in a charger cable or USB cable! You have to wait until the battery is empty (0%).
5. After your device shutted down because the battery is empty, plug in the charger cable, power on your phone and wait until it charges to 100%. Don't remove the cable until it's charged to 100%!!!
6. Repeat step 4 and 5 for a second time.
After that process your battery is calibrated. I hope that's your problem. It's worth a try.

Thank you both I will try all the things mentioned however...
I have flashed another ROM the cyanideL ver 5.1.1-RC-15.6-klte
Then I flashed ktoonsez kernel sgs5 profile balanced bull v4 again of course after wiping etc
And wow fast and smooth. I've never seen my phone this fast and battery life so far has been incredible.
Left the house 100% at 530 this morning its 4 pm now and I'm at 85%
after about 2 hours of usage.
I will also try what you two have mentioned.
Thank you for your help

No problem. And try the newest Version from google play services because that's a very battery friendly version: http://www.apkmirror.com/apk/google...ices-8-1-05-2218116-238-android-apk-download/

Delivery reports of SMS are not shown despite ticking in device & ok from net work operators

having tried cm12, blisspop, I found that battery life is better on "almost stock" touchwiz roms ... touchwiz roms are approximately 1.5X better

Battery Issue

So, I have been using the Moto G4 Plus ( Indian Variant -XT1643 ) for a quite few months. Then 1-2 months ago, I rooted it, first with superuser and then replaced it with Magisk. I am using ElementalX kernel. But then after some days , the battery started acting weirdly. It drains very quickly. Also if I charge the phone fully and then reboot in bootloader , it drops to 15-16 . Sometimes the phone switches off at 10% battery. Even in idle, the battery drains very fast. When charged to 100%, the battery page of settings shows something like 45-55 mins left and that too varies. Currently on 56% it's showing 51 mins left. It's just 1 hour ago when I charged my phone to 100%. Is it time to replace the battery or is it a software issue as it drops to 15% in bootloader even if fully charged. Any help is appreciated. Thanks in advance.

I have the same problem but only with magisk, wih SuperSU everything is ok ?

Alright, I will try with SuperSu and update you. Thanks for the help.

Its software issue, may be ex kernel, magisk, supersu or any other app is draining it. Use better battery stats or similar like it and see who is sucking your battery juice.
And as you have already rooted your phone then try any custom rom as they dont have its problem (some may have also). And if wanna stick to stock rom then reset your phone and root it and then use for a while you will get the difference from before and now.

Ok. Its good to know that it's a software issue. I already tried factory reset but it didn't help. Strangely, the battery is fine now. I drained it completely and charged to 100%. Maybe that might have reset the battery stats or something. Anyways , if the problem still persists I will try custom ROM. Thanks a lot.

Hmmm, I never had battery drain issues while using ElementalX kernel rooted with Magisk (14.0).
At least not while using Motorola stock Nougat with the above.
Maybe your battery just lost its calibration as you assumed.
