I am facing battery problems. I fully charge my phone and after a few short calls my battery level drops down to 90% remaining level. Am I the only one facing this problem ? I have made necessary changes to improve the life.
1) reduced the back light to auto shut after 15 seconds of inactivity
2) standby mode in 30 seconds of inactivity
3) backlight is set to the second bar.
3) GPRS is not connected bluetooth is off and wi-fi is off.
I just purchased this phone 2 weeks back so the battery is brand new
Battery info: model number is PM16A, 3.7 Volt DC @ 1200 mAh (DynaPack)
I need to recharge the battery every 24 hours. Is this NORMAL ?
I would appreciate any suggestions.
Thanks.
It's normal. Battery life in pocket pcs and pocket pc phones in general is like that.
I've always noticed that in my PPC and my Prophet, the battery drops down REALLY fast to 85-90%. Then it slowly goes down. Then around 60%, it again gets stuck. Then it goes down again, but very slowly. You'll get a good 2 days of usage with moderate use.
Though I usually charge my phone every night, when it is at about 55-60%.
In the morning when I take it off the charger, it drops down to 90-92% after I only read 1-2 SMS messages and maybe make a short 5 minute call. It's normal.
My battery performance has been pretty solid up until recently. Without reason the phone drains massive amounts. As of writing this, I've been on wifi for about 5 minutes and it has lost 4% already. In standby with wifi and sync off it loses about 1.5% per 10 minutes.
I have tried the following to mend it without success:
- Flash new sense rom / cm 6.1
- Reset battery stats after doing the charge cycle when u power it on, charge, power off, charge, etc.
- Replace the battery with a brand new one
I have been running juicy's OC rom for about 3 months without issue until this became prevalent. Does it sound like a hardware issue? Fried CPU perhaps?
Battery calibration is simply done by running it down completely until the phone shuts off by itself...
Then remove the battery, wait 10 seconds, insert again, repeat...
If the phone shuts off again in less than a few minutes you're done.
Now remove battery and hold power button for 1minute.then insert battery.dont switch on the phone. plug the charger and recharge the battery fully until the green light is on...
then remove battery,hold power button for few seconds,insert it and switch on the phone...
yes its done......
do this initially once in 3-4months when the phone is new.then ince a month after a year to gain maximum battery performance...
REMEMBER THIS WILL NOT DRAMATICALLY IMPROVE YOUR BATTERY LIFE....
BUT THIS WILL SAVES YOUR NEW ONE TO BE DEAD BEFORE AGE
DONT EXPECT MORE FOR ALREADY SWOLLEN OR DIED BATTERY...
There are programs that drain battery by endless vibration... will that do? Or we must use the phone normally until power dries?
I don't think that draining battery by endless vibration is a good idea.
You can drain it by using heavy programs like windows media player, wifi etc.
Thanks...
Thx. Calibration done!

You wouldn't want do it if on a regular basis but you can try turning phone off, pulling battery out, putting it back in after a minute and if that doesn't work, try my method.
I would wait until the battery is super low and then reset network settings under the reset menu. Power down, pull battery and sim wait 30 sec to a minute and replace everything. Then plug in the phone first and then reboot. Let it charge completely and for about 20 minutes more after it reaches 100. If you do a lot of rebooting I have found the phone has issues. I only reboot with the phone plugged in, otherwise it drops 2% every reboot..
Be careful, I did that with a ZTE Zmax 2 once (75% charged battery) and it sent a phone into a bootloop. The only means of fixing it was that I luckily had a 2nd Zmax2 laying around and used its battery on the bootlooped phone which remedied the problem. Both batteries work fine , I just swapped them between the two phones.

I used to worry about this too. This is my first LG product and it MAY be different but at the Sprint store the first thing they would normally do is pull the nattery to look at the ESN. They never bothered to power it doen forst so I asked a couple times and was told it will mot hurt anything. I had Samsung products for uears and have done battery pulls at all levels of charge and for many reasons, but I never had a problem as long as the battery had enough juice left to boot the phone. If not I had to charge it, LoL.
Just thought I would share, I personally wouldn't worry.
I know on my old Nexus 6 pulling the battery with phone on was only an issue with fsync disabled using a custom kernel. I think most phones have built in protection to stop this from damaging the file system.
so a battery pull is your fix? lol some ppl should be hard resetting every so often regardlessi reboot at least once a day
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
While I don't get extremely bad battery drain. The few times I've noticed it going down a bit faster than normal have had Android system at the top of the list or at least 2nd in place. A reboot usually fixes it for a while. This has happened in every ROM I've tried. Also I swear that stupid Wi-Fi scanning when WiFi is off option in locations settings turns itself on when it feels like it. I rarely turn my location on and I've checked a few times and that feature is on for whatever reason
Power down.
Pull battery.
Hold power button for one minute to discharge any juice that may be on the motherboard.
Let phone sit for 30 minutes.
Put battery back in.
Power up.
The motherboard and battery should now be re-calibrated. If you still have problems, try a new battery.
Hello, i have an SM-N9005 and have always thought it was some kind of software glitch.
Now upgraded and tested several Nougat and Oreo Mods and same error. Running on RR 8.1 Mod
Even when fully turned off the battery drains 6-8% per hour.
If I take it out OK
But then when installing another fully charged battery the phone will not restart until a power cable or power bank is connected for a few seconds so it lights up the charging meter. So I can't just take out the battery overnight or while travelling
I just very annoying. Have replaced the power connection socket but same after that
Also heats up badly with CPU up to 65-68 C or more but has now turned down clock speed to test
Test with a stock rom only .
But reads to me as a problem on the motherboard .
I have similar issues. Any resolution software related?
