Extended Battery Charge Reporting Sucks

I charged my Samsung extended battery to full then reset the battery stats but my battery reporting is still terrible after 3 days. As soon as I unplug it from the charger it is automatically at 98% and drops quite rapidly.(~3% every 5 minutes of active use)
Would allowing the battery discharge to automatic shutoff alleviate this problem? That hasn't happened naturally yet

That can be normal behaviour. Mine does it sometimes too. 95% and up on any phone will be that accurate. As for your drainage problems, your phine is doing something heavy duty in the background. And/or you are running full brightness. I am getting 4.5 screen time on average. I was able to get over 5 hours this weekend. For me to get 3% every five minutes i have to be playing a game or been downloading a large file over cellular data.

Seems like you either have a bad device or you have an app or two that is killing you. Something that gets push notifications for example, like a messenger or something similar

I have been experiencing this as well, my stock 1850mA battery seems to outlast my extended 2100mA battery by about 20%. Has anyone else seen this behavior? I have been thinking that maybe I got a bad battery.

I have just installed Battery Monitor Widget as recommended in a battery related thread in this forum, and it is showing my extended battery as having 1750mAH. I don't know why and I'm not sure what to do to fix it, and my battery life is pretty awful.

Battery Monitor Widget allows you to manually change the battery capacity.
Touch the gear symbol, select ""Monitoring", then "Battery capacity". Enter 2100 if you have the CDMA extended battery.

Yes, I saw this - but if it's getting the capacity from the phone, and the phone is reporting 1750, isn't something wrong? Doesn't that mean it will stop charging the phone prematurely because it thinks it is at max capacity?
In fact, I just remembered the stock battery is 1850 mAH so I have no idea where the 1750 is coming from...
Thanks for your reply.

its coming from the GSM version because it has a 1750 mAh battery.
battery monitor widget is not pulling from the chip inside the battery, it is just guessing your capacity because it knows its a galaxy nexus. hence you have to manually enter your correct capacity into battery monitor widget yourself.
also remember this fuel gauge is not capable of giving current readings. so battery monitor widget is guesstimating current based on extrapolating the drop in your percentage among other tricks the developer uses.

Thank you very much for your reply. It makes sense what you're saying, I took the setting in BMW literally as it states:
"Override capacity provided by phone"
Thanks to both of you for the help. Now I still need to find out why my battery life is sooooo bad...

[Q] Battery Life....I Just Don't Get It

Hello,
I know, I know, there are many threads on the battery issue. But I'm struggling just too hard with this. I've researched and read every thread on xda and other forums elsewhere to glean as many tips as possible which has certainly helped, but something just doesn't seem right.
Currently I'm using a battery saver app - Easy Battery - which does help considerably during idling and off-use periods - the DINC at least has some charge left to make a few calls and check voicemail when I'm finished on the job site and going home, but when actually using the device it seems like I can just watch the battery drain down - it's really disheartening.
My device details are below. I'm using the best performing kernel I've found after much trial and research. I've deleted about 10 - 14 resident system apps to improve performance - the DINC is as bareboned as it can get. Maybe I can delete a few others still.
I understand JB is more of a battery drain, but can it be this bad? After a full night's charge, I wake up and check my mail in bed, some quick online news browsing, looked at one or two video clips, 5-10 minutes each. I spent about 20 minutes on the phone. Looking at my screenshot, the battery's drained 40%, IN 37 MINUTES!!!
Also, some hours of the day the battery life seems better...? Sometimes I can perform general tasks on the phone, watch a few video clips, do some reading for an hour straight sitting over a pint and there seems to be comparatively little drain at all, certainly not 40% worth of battery drain in a half hour. I just don't get it.
Am I need of a new battery? Is there a super battery for the DINC? Should I be limiting the number of 'recent apps' in the Recent Apps switcher? Is there another Performance setting I'm overlooking? I/O scheduler setting?
Please, please, what can I do - any additional tips would be greatly appreciated. I love the DINC. For me, it's the perfect sized phone that I like, outside of any device functionality at all. Maybe I'm moving on though. Ugh.

if you have the original Dinc 1400 mah battery, maybe your battery just doesn;t hold a charge anymore.
what I do is I don;t even charge my batteries in the phone really. i find that when I charge the battery in the phone, the battery drains quicker. I bought an universal external charger and rotate a couple of 3500 mah batteries after running them down completely. I carry a spare with me if I need but usually my phone lasts into the next day.
you can get 3500 mah batteries for about 5$ or so on eBay(last I checked). the universal charger goes for 9.99 on NewEgg or Amazon. good investment

What I've done on CM10 to try to extend battery life:
Keep my screen locked at 25% brightness but can toggle into 100% or auto when necessary. On CM9 (before I was crack-flashing CM10) I played with auto-brightness levels that were discussed in this thread and they did help. 'Auto' is normally too bright for me, anyways.
Turned off background location reporting in Maps. This will neuter some things in Google Now, tho. You can see how often your phone "checks in" here.
I used SmartAssV2 on CM9 but went to interactive on CM10. No quantitative data that it helped battery life, but it passed my eyeball test after a week+ on both. My phone is flaky on under/overclock so I keep it at 245/998.
I leave 3G on, WIFI on, GPS off, BT off 99% of the time.

Hmm, great suggestions. An external charger(though I'd prefer not to be regularly opening the casing, I'll look into it); 3G radio off; locking brightness at 25%, toggling when necessary; background reporting off. I'll also keep experimenting with a governor and try a week on interactive. A really great kernels guide: http://forum.xda-developers.com/showthread.php?t=1369817.
I have a spare original battery so I've got that in and giving it a powered-off charge. See how that does on top of other adjustments.
BTW Both batteries I own are model BTR6300B 3.7VDC -- 1300mAh 4.81Whr - tekweezle mentioned a 1400mAh battery and other available batteries that are at 3500 mAh now - I guess I'm looking into new batteries as well -
cheers for the responses -

I recommend just getting a new battery on ebay for 5$. Also get juicedefender it doubles my battery life. Also try tiny/pons cm10 rom that has great battery life.

Definitely getting a new battery; I'm already using tiny's rom which continues Pons' CM10 rom builds. Really great -
cheers

Obviously, if you are using your phone non stop, you'd be lucky to get 6-8 hrs of usage. But the true indicator of what a phone does is how often you don't have to be attached to a wall outlet or hunting for one.
I don't know if others get similar results as me but this is more or less typical of me with light to moderate usage-checking email, Facebook, some Web browsing, occasional phone call or text message plus leaving my phone on overnight in stand by.
By the way, how I am on pons/tiny 12-9-12 and working well.

btw, this is the external battery charger I am using. awesome thing is that it charges at 600 mah so my 3500 mah batteries charge up in 4-5 hrs or so. since it has moving pins, you will be able to use this to charge any flat battery for any cell phone or camera you might buy in the future.
the SEIDO HTC EVO modified one I got on ebay charges at 500 mah and for some reason it takes 8-11 hours to charge a battery and I am finding out now that it doesn;t even charge them completely even when it thinks they are completely charged. i take a battery that is charged in this and put it in my other charger and still needs charging of about 10 percent!

I get something similar, probably a little worse, in send/recv about 50-100 texts a day and checking 2 gmail and 1 exchange account constantly. My battery does tank when I'm actively using the phone and really all I can do there is manage the brightness of the screen. I've been doing my tweaking to try to increase battery life when I'm not using the phone. In 7 hours last night it only went down 3%. When I first started using JB it was 10-12% a night.

Great, great info - love these forums, and I love android!
tekweezle - could you tell me exactly which 3500 mah battery you're using with your DINC? Also - no issues whatsoever with the pons/tiny 12-9-12? I thought I saw a few things reported with the 11-28-12 and stayed away from it, staying with the 11-25-12.
cheers!

i have an expensive SEIDO battery that I bought from Amazon in the beginning for about 59$. Never thought the capacity was all that great till i found out that my battery wasn;t even being charged completely. not really worth the money but at the time, it was all that was available

The others, i just bought generic flavor of the day batteries off of eBay for 5$ each. basically throw away items. just search for HTC 3500 mah Incredible battery and you should get some hits.

no real operational issues yet with 12-09-12 Rom. minor annoyances with video playback. actually, the still camera works fine but video camera doesn't save files.

[Q] [q] Is this what a dying battery looks like?

I noticed when I was looking at battery stats (trying to figure out what's eating the battery; very little in the way of apps installed)
I bought the phone last week, but I bought it used on eBay. It came with the original box and the manufacture date is 6/30/12, so I figure this was someone's everyday device for 10 months.
The reason I ask is that sudden dip from 20 to 30%. And the other reason I ask is that I only get about 10 hours with 3 hours of screen-on time on a full charge. If the battery is just losing capacity, that's fine - I'll get a ZeroLemon 2300maH battery and I should get much better life. If the battery still has close to full capacity, then I'll get an extended-capacity battery. I just need some guidance as to whether or not it's crapping out so I have a better idea of what to buy.
Thanks!

Jump is weird. Could be the battery is flaky. But I would make effort to reseat it. I want to see what BetterBatteryStats says about that terrible wakelocking, though.
You can delete batterystats.bin from /data/system. Everyone says it does nothing. But I do it anyway. Because I can.

My stock battery usually gives me 7-8hrs of standby and 3hrs of screen time.
Zerolemon 2300mah gives me 20hrs of standby and usually 5hrs of screen time.
You can check in the accessories section in the zerolemon 2300mah that I've posted some of my results via screenshots.
About the dip, I'm not sure I've never noticed that on any of my batteries.

Jump has been there consistently. Had the phone 4 days, and every day when it hits 30% it drops to 20%.
Installed Betterbatterystats and I'll see what's keeping it awake. It does seem to be awake an awful lot compared to my old Atrix (switched to T-Mobile a month or so ago, and just got the phone after I was switched for a bit), which got way better battery life.

10 hours with 3 hours of on screen time is just about average for the stock battery.
I would recommended getting the zero lemon 2300 mAh slim batteries if you're lucky enough to place an order for them. They only restock in small amounts and they disappear quick.

Well that's good to know. They're in stock right now on Amazon so I'll pick up the 2-pack with the charger.

OK so far the phone has spent half its time unplugged staying awake, and about half of that is being caused by DeskSMS. I got a trial a long time back and decided not to bother because I didn't use it, and when my google account restored to the phone, it apparently got installed and I didn't notice. I've uninstalled that and we'll see what else happens. Very thankful for the BetterBatteryStats suggestion; I'd never heard of it.

Well the battery is lithium ion. With repeated charging the battery loses capacity. If the battery is the one that came with the phone, buy a new stock one for cheap off Amazon. That is if you use NFC and have a certain fitted case. If not, go for an extended battery by reviews on Amazon and XDA. My battery is from December and I haven't noticed any decrease yet. The temperature of which your phone runs and the temperature of the environment also effect battery life.

Great news, everyone. Desk Sms was the culprit all along. This is 3 hours of Netflix and then sleep over night. Just a couple wake locks that I can attribute to emails received overnight.
So out turns out the battery other than the weird drop, at least with the power saver on.
Thanks in particular for the Better Battery Stats suggestion. Without it I would have been majorly confused.

Glad you were able to get it all figured out. Wakelocks are VERY annoying. Search for kms.apk if Mediaserver is ever draining your battery in the future, it is a common battery draining problem as well.
If you're on TouchWiz using Power Saver, I'd recommend disabling it. It throttles your CPU in half. This may cause instability, or overheating problems or sometimes even battery drain ironically. I do however recommend, KT747 kernel with changing govs, and I/O scheduler and using Team Kernelizer tweaks. Try Eugene's CPUSleeper and it may help put DeskSMS to sleep for good. And how could I forget? Definitely try Greenify. It makes apps behave akin to iOS devices. Best of luck.

The problem with Greenify, in this case, is you can't hibernate apps that send notifications, or you will never get them.

The power saver doesn't bother me. Being in the notification area makes it easy to toggle and performance has been fine. Better Battery Stats says it gets up to 1 GHz Mac and that is plenty on the web or Facebook or Netflix.
I had assumed the media server popping up was due to Netflix streaming. It hasn't been back today since recharging. If it comes back I'll look more at disabling. Today battery life has been great. 12 hours with 2 hours of on time and at 45 percent. I definitely over reacted to the drop and it must have been Desk SMS which never should have been installed.

If anyone has any issue with their battery sprint corp stores have a tester takes about ten min. They won't have a problem doing it if you're nice, sprint or not. It will either end up excellent marginal or poor... they don't charge for the test.

[Q] Zerolemon my ass!!!

I am posting screenshots from my Note 2 after using the Zerolemon 9300mah battery for 2 weeks.
Please excuse the clarity, I was using a filter at night time.
Now of course I have followed all the procedures of the 6 charge cycles and draining the battery to 2%. I keep only data and gps on, I don't use bluetooth, WIFI, NFC, or any other bloatware. Screen brightness is at max the majority of the time, and so is sync. I do some browsing and youtube, and make some short phone calls during the day. CPU and GPU levels are at normal stock levels and speaking of which, I'm running stock rom with perseus. Obviously the first...I should say 10-12% gets eaten up in a flash from 100%, and after it does slow down. On the whole though, as you can see its made it to around 16 hours.
Bottom line is, people do claim to reach at least 3 whole days, if not 2, with heavy usage. I was hoping zerolemon would do this for me but clearly not. Do I have defective phone, or am I just asking for too much? Any help is appreciated! :good:

I get that with stock battery and better...
That's not a good for 9300 mAh battery!
Maybe sync is taking a lot from battery..
Or maybe an app using do much power in background.. Or deepsleep is not working correctly.. Low signal also can affect the battery too..
9300 mAh should at least get you 15 screen hours.. While u only got 6..
Formating the phone completely maybe? That would solve too many issues..
Also if there is a warranty for the battery, maybe getting a replacement? Maybe it's damaged or simething..
Sent from my GT-N7100

after 9 hours of work, i usually used 20%.
which is much better than stock battery, with it, it went down under 50% everyday.
so i am quite happy with zerolemon

[Q] Mysterious Battery Issues

Hey all.
I have my LG Opt. G Pro E986 on Stock Firmware. It's rooted and has this Kernel http://forum.xda-developers.com/showthread.php?t=2363330.
Overall I'm ok with my battery life, around 2 days of usage with 6 hours screen-on time. Standby time is very good.
My problem is the following:
If my phone is around 30% battery it starts to drain a lot. I don't even have to use it and it's empty within 3-4 hours. The power consumption at this point is immense and i can't figure out why, there is nothing I am doing different than normal use. I even try to use it as less as possible at this battery level, but it just keeps going down.
I have Quad-Core management always on, power saving mode always off. I also do not have any other power saving applications or settings running.
Processor is on stock clockspeed, Voltage is on stock too, no Cores are disabled.
I searched for draining apps via Battery Stats Plus but did not found anything.
Useless Tasks/Processes etc. are disabled via App Quarantine.
I have this problem for a long time and now decided to ask for help.
Does anyone have the same problem? Can someone help my fix this issue?
Thanks a lot.

I see it too on stock battery but not on the zerolemon 3150 mah battery...it seems related to the way the phone measures battery %ge for the stock battery I guess

Well ok, if this is the case is there any way to fix it without buying a new battery?
I ordered one with 3800 mAh, but it was crap and didn't even last half as long as the original one, so i wasn't able to compare them regarding my problem.
